1 INTRODUCTION
The TTC-1000, Transformer Temperature Controller is a mission specificprogrammable controller that measures up to two different probe temperatures,load and calculated winding temperature. The user can program four (4)independent outputs based on the state of pre-programmed temperature setpoints, time set points, load set points or the outputs themselves. The controllercan measure any two of top oil, winding, LTC tank, or ambient temperature toaccuracy of ± 1 ºC and does not require calibration. Calculated windingtemperature is based on the methods of ANSI C57.91 and uses measured top oiltemperature and load current.
The outputs can be used to:
Control cooling fans and pumps.
Provide high temperature, LTC condition, and cooling system performancealarms.
Provide a trip output.
The TTC-1000 is substation hardened and designed to operate over a widetemperature range of –50 to 85 ºC suitable for installation in outdoor cabinets.
The TTC-1000 contains many features including:
Measures temperature from -35 to 160 ºC.
Does not require calibration.
Optional 0-1 or 4 - 20 mA analog outputs.
Optional dual probe version for top oil and the heated well.
Optional aux CT input for calculated winding temperatures.
Patented Load Pickup Cooling™ set points for early activation of coolingbased on sudden increases in load.
Comprehensive Patented Dual Algorithm LTC Condition Monitoring™ for thedetection of both slowly and quickly evolving problems.
Universal probe kit includes thermo well fitting adapters and probe sleeves.
Optional magnetic mount temperature probe when a thermo well is notavailable.
Reports Min and Max Temperatures, time stamped with date and time.
Data logging.
Periodic exercise of cooling fans.
Automatic swapping of lead and lag fan banks.
V4.41x, May 22, 20082
Four independent temperature set points per probe.
Cooling system performance monitor to alarm when cooling is commandedbut the current draw of the cooling fans or pumps is outside a specifiedrange.
Six scheme logic programmable form C relay outputs, all trip duty rated.
Dedicated programmable for B alarm relay in small form panel units and formC alarm relay in large form panel units and NEMA units.
Remote/Local Communications through RS-232, no special softwarerequired.
Flash memory for convenient firmware upgrades.
Same unit operates from 38 to 160VDC or 120VAC and is immune toreversal of battery voltage polarity.
Available in either compact panel mount or a 304 Stainless Steel NEMA 4Xenclosure.
Optional MODBUS or DNP3.0 Level 1 communications for reading analogsplus status and remotely commanding cooling via RS-485 or Multi-ModeFiber Optics.
Two optional optically isolated inputs for remote cooling control by SCADA,reporting status from liquid level or sudden pressure alarms over DNP3.0, orfor selective blocking of outputs.

3.2 Power Hookup
The TTC-1000 can be powered from either DC substation battery betweenvoltages of 38 to 160 VDC or from AC voltage of 120 ±10% VAC. On small panelmount units (Figure 3.2a) power is connected to terminals 1 and 2 of barrier styleterminal block TB1 and on TB3, terminals 1 and 2 (Figure 3.2b) on the largepanel unit. On NEMA units (Figure 3.2c) power is connected to terminals 1 and 2on TB-3. The TTC-1000 is not sensitive to polarity because it uses a bridgerectifier on the power input. This feature eliminates the risk of damage due to thereversal of power applied to this input.
Figure 3.2: Power Connections
NOTE:
1. The chassis of the panel mount unit or NEMA 4 enclosure MUST bebonded to ground. Panel mount units must be bonded to the groundbus in the control cabinet and NEMA units must be bonded to the maintransformer grounding on the transformer tank. It is especiallyimportant to ground the unit when operating from 120 VAC.
2. For NEMA 4 units it is strongly recommended that the external ¼-20ground stud be utilized for proper grounding.
3. When powering from AC substation service, it is essential thatappropriate surge suppression for lightning protection is installed onthe AC mains feeding the unit. An application note, ANTC003.PDF, isavailable on our web site, www.advpowertech.com. This note hasdetailed information on addressing this problem.

3.3.3 Magnetic Mount Probe (TTC-PROBE-02) Installation
A magnetic mount probe (P/N: TTC-PROBE-02-xxx) is available for surfacemounting to the LTC or transformer tank when a thermo well is unavailable.
To mount the probe you will need:
RTV silicone sealant suitable for the outdoor applications and rated for themaximum operating temperature.
Thermal grease (supplied with probe).
To install the probe:
1. Coat center probe area with a liberal coating of thermal grease as shown inFigure 3.5.
Figure 3.5: Magnetic Mount, Application of Thermal Compound
2. Place probe on the wall of the transformer or LTC tank to be monitored. Thelocation should be as high as possible on the tank, but bellow the top level ofthe transformer’s or LTC tank’s oil level. It is recommended that the probe beinstalled on the LTC tank wall away from direct exposure to the sun. Directexposure of the tank to sunlight can cause the surface to be at a slightlyelevated temperature above normal, which may cause the differentialtemperature to be in error. See Figure 3.6.
Apply a liberal coating of
Thermal Grease
V4.41x, May 22, 200816
3. Place a bead of RTV silicone or other suitable sealing compound around theperimeter of the probe to seal the probe surface from moisture. See Figure3.6.

3.3.4 Probe Lead Connections
The probe leads are color-coded and are inserted into the terminal block in thefollowing sequence:
Probe Panel Marking Wire Color Terminal #
1 COM White 12
1 TMP Red 11
1 REF Black 10
2 COM White 9
2 TMP Red 8

V4.41x, May 22, 200817
Figure 3.7: Probe Connections
NOTE:
It is extremely important that the probe shields be bonded to the TTC-1000case. Failure to do this will allow surges to enter through these leads anddo internal damage to the TTC-1000
For dual probe units, you must use both temperature probes for properoperation. The unit will continuously alarm if you fail to use both probes.
If a second probe is unavailable, you can use two 1,000 ohm resistors. Oneend of one resistor to REF, the end of the second resistor to TMP. Tie theloose end of both resistors to COM.
It is noted that probes can be supplied from lengths of 10 foot to 250 feet. Whenusing existing substation wiring with probe lengths less than 250 feet, it isimportant to connect the probe’s shield drain wire to the shield the cable andobserve that the total wiring length does not exceed 250 feet. Also it is importantto ensure that the TTC-1000’s chassis is grounded to a point close to where theshield drain wire terminates as shown in Figure 3.8.

3.4 Auxiliary CT Input for Calculated Winding Temperature
Models TTC-1000-xx3x and TTC-1000-xx4x are equipped with an auxiliary CTinput. A split core CT is supplied with these models and is intended to be appliedover the secondary leads from the bushing CT. To apply the CT, first open thewindow by inserting a small screwdriver in the clasp holding the core halves
closed. Select a CT secondary tapensuring that it is either shorted oralready in use. It is recommendedthat B phase CT be used for thispurpose. Wrap the wire with severallayers of electrical tape and applythe split core CT over the wire and
snap it closed. It is highlyrecommended that a cable tie beapplied under the split core CT tokeep it from sliding down againstthe lug. Figure 3.9 illustrates theassembly of the split core CT ontothe bushing CT secondary.
Figure 3.9: Split Core CT Installation

Each relay iscapable of carrying 10 Amps at 230 VAC. Configure these contacts for coolingcontrol, high temperature alarms, or LTC condition alarm. Programming thesecontacts will be discussed in Section 4.9.
NOTE: The ability for these contacts to break its load is based on a numberof factors including voltage applied and the type of load. In general, there isa higher tendency for contacts to become welded shut at higher voltages.Therefore, protection devices, such as MOV’s are highly recommended ifthese contacts will be required to break more load current than that shownin the Specifications.

3.6 Unit Alarm Connections
The single form B relay is utilized to provide a dry contact closure for alarmconditions. While the unit is energized, the alarm relay is energized. This allowsthe unit to provide an alarm should the device lose DC power or becomes de-energized.
The TTC-1000 monitors five conditions: Processor (DEVICE), Temperature(TPROBE), Winding (WNDG), Communications Processor (CPROC) and ManualMode (MANUAL). The TTC-1000 allows the user to enable or disable any or allof the alarm conditions, except the Communications Processor alarm, throughprogramming. The user can also program how each output reacts when analarm occurs.
Figure 3.12a illustrates the connections to small panel mount models, Figure3.12b illustrates connections to large panel mount models, and Figure 3.12c theNEMA 4 models. Note: NEMA 4 models with board serial numbers ending in Awith DNP3.0 and analog outputs will only have a normally closed alarm relaycontact.
Figure 3.12: Connections to Unit Alarm
The user can program each output in how it reacts when either a Processor orTemperature alarm occurs. The user can set an output to pick up, drop out, orstay in its current state when either alarm occurs.
3.7 Telemetry Connections
TTC-1000 provides a 9 pin female subminiature D connector on all models.Panel mount models can either have analog outputs or an RS-485 interface forDNP3.0 communications. NEMA 4 models can be equipped with both analoginterfaces and an RS-485 interface for DNP3.0 communications.

3.7.2 Analog Outputs
The TTC-1000 is available with up to two analog outputs configured as currentloops. The source for each analog output can be selected from probe 1 (P1),probe 2 (P2), or calculated winding temperature. The analog output is designedto operate with a series resistance of 9,500 Ohms when set to 0 to 1 mA or 450Ohms when set to 4 to 20 mA.
The analog outputs are connected to either terminal block TB2 on both panelmount and NEMA 4 models with serial letter suffix ‘A’. For these models Figure3.13a illustrates the connections to both panel and NEMA, Figure 3.13billustrates the large panel, and Figure 3.13c NEMA 4 models with a plug-indaughter board. NEMA 4 models equipped with a plug-in analog output moduleutilize TB4 for connections to the analog outputs.. The terminal marked + is thecurrent source output. The connection marked – is the current transmitter’s returnand is tied directly to the chassis ground on non-isolated outputs and isolated
from chassis ground when the isolated output is used.

The analog outputs A1 and A2 can be programmed for 0 to 1 mA or 4 to 20 mA.Both analog outputs are identically programmed. Consult Section 5.1 forprogramming the scaling of the analog outputs.
3.7.3 RS-485 for DNP3.0 Communications
Units equipped with the optional DNP3.0 communications interface contain aseparate microprocessor to handle all overhead functions associated with theDNP3.0 protocol without affecting operation of the transformer cooling controland monitoring. The small panel unit and the NEMA units use a plug-in module
that contains a half duplex RS-485 asynchronous communications interfacecapable of supporting multi-drop topologies with a single shielded twisted paircable. This circuit is part of the main board in the large panel unit but still uses aseparate processor. On the Small panel and the NEMA units, A jumper, J2, canbe selectively installed if the TTC-1000 is either the first or last device on the twowire communications bus. Figure 3.19c illustrates the location of J2 on theCommunications Processor Module. Jumper J2 must be installed if the TTC-1000 is either the first or last device on the multi-drop communications bus.Installation of the jumper connects a 120 ohm termination resistor. Termination isvital to reduce reflections which affect proper operation when the length of thecommunications bus is long and/or there are many devices connected. The twowire module uses a fail-safe RS-485 transceiver that insures that incorrectoperation does not occur due to an open or short circuit on the communicationsbus. While the TTC-1000 is immune from shorted or open communications link,other devices may require the use of bias resistors. On the large panel unit, an
external resistor can be placed between the A & B terminals as there is nointernal jumper.
NOTE: For small panel mount versions, the unit contains the jumper but itis not installed. To install jumper J2, the unit must be disassembled. TheRelay Board must be removed to gain access to the CommunicationsProcessor Module. J2 is located on the Communications ProcessorModule. It is noted that an 120 ohm resistor (a carbon or metal film resistorrecommended) may be installed externally between rear panel terminals A& B on the plug-in terminal block TB2.
The use of shielded twisted pair wire or cable is essential between nodes of thecommunications bus. Connection of devices on the bus should be carefullyconsidered. Every device on the bus must be connected in a daisy chain fashionlike a string of Holiday lights. The devices on the bus should never be connected
V4.41x, May 22, 200823
in a star configuration. Polarity of the connections are also critical and should becarefully observed and followed. For example, the “A” connection also known asthe TD/RD should be connected to every other node’s “A” connection. Likewisefor the “B” or the not TD/RD line. Figures 3.14a, b, & c illustrate connections topanel mount and NEMA 4 models.
If using a wired RS-484 connection, it is essential that the termination be in thevicinity of the TTC-1000. As this is al low voltage communication circuit, groundpotential rise or other surge phenomenon will damage the unit. It is preferred touse a fiber connection directly from the TTC-1000. The RS485 output is intendedfor connection to a LOCAL wired to fiber conversion or other device located onthe transformer or in the control cabinet. .
Figure 3.14: Panel Mount and NEMA 4 RS-485 Connections
There are many good references on implementing multi-drop RS-485communication links from the semiconductor divisions of Texas Instruments,National Semiconductor, and MAXIM Integrated Products.
3.7.4 Fiber Optic Interface for DNP3.0 Communications
Both panel and NEMA units can be equipped with the optional DNP3.0communications interface with a multi-mode fiber optic interface. NEMA modelsuse a plug-in Communications Processor module. The interface utilizes aseparate microprocessor to handle all overhead functions associated with theDNP3.0 protocol without affecting operation of the transformer cooling controland monitoring. Fiber optics are recommended for substation installations as itavoids the problems of ground potential rise issues commonly associated withdirect metallic connection.
The optical interface operates at a wavelength of 850nm with 50 or 62.5 micronmulti-mode fiber terminated with ST style connectors. As with all fiber opticcommunication links, the optical budget is an important number in determiningthe maximum distance that can be spanned with a specific manufacturer’s fiber.All optical fiber, whether it is glass or plastic core, has a specific loss in dB per

kilometer. It is important to remember that optical losses can vary frommanufacturer to manufacturer for the same core diameter and material. Themaximum distance which can be spanned is defined by the following equation:
DISTANCE in kM = (Optical Budget – 3dB) / Optical Loss in dB/kM
The optical budget for the TTC-1000’s optical interface is 9.1dB. Therefore, using62.5 micron glass core fiber, with a loss of 4.0 dB / kM the maximum distancespanned is approximately 1.5 kM or 4,900 feet.
The fiber optic interface has the ability to operate either point to point or can bedaisy chained with other intelligent electronic devices. A switch, S1, is providedto allow the user to select either point-to-point or repeat. Setting S1 to REPEATpasses the signal received on the fiber to the Tx fiber port without any delay.Panel mount models can be set to Repeat Mode via a setting provided. Pleaserefer to Section 3.7.5 for Repeat Mode setting.
In addition, three diagnostic indicators are provided for troubleshooting: Txindicates that the fiber interface is transmitting data to the DNP master, Rxindicates that the fiber interface is receiving data from the DNP master, and Re-Tx if S1 is in the REPEAT position and received data is being re-transmittedthrough the Tx port to the next IED in the chain.
Figure 3.15 is an outline drawing showing the fiber interface and the location ofswitch S1 and diagnostic indicators Tx, Rx, and Re-Tx.

3.7.5 Setting Repeat Mode on Fiber Optic Channel
On units equipped with a fiber optic communications channel you can configurethe fiber interface for repeat mode. This passes incoming data to the transmitchannel transparently.
To change this setting, access the PROGRAM menu from the front panel asdiscussed in Section 4.1. To set the repeat mode from the front panel, press the
or arrow button until the following menu item is displayed:
Once the setting is accepted, the repeat mode will be enabled.
3.8 Optically Isolated Inputs
These inputs are not available on the small panel unit, but are available on boththe large panel unit and the NEMA units. Models equipped with inputs containtwo optically isolated inputs, IN1 and IN2. These inputs must be wetted from anexternal power supply between 38 and 160 VDC. Connections are made throughplug-in terminal block TB1. These optically isolated inputs may be used by theprogrammable logic to control or supervise any output. These inputs can also beused to communicate status information from devices such as the liquid levelalarm or sudden pressure over DNP3.0. IN1 and IN2 can be programmed to beLEVEL or PULSE active. Figure 3.16 illustrates these connections. The use ofshielded cable is recommended.

NEMA 4X Models, TTC-1000-4XX, are equipped with a 13 Watt thermostaticallycontrolled heater and a specially designed vent that allows moisture to escapeand does not allow moisture to re-enter. The heater can be operated from DCvoltages of 38 to 160 or at 120 VAC. For convenience, the heater circuit isconnected to TB3 terminals 1 and 2. However, the user can connect the heaterto a separate power source.
The thermostat turns off the heater circuit when the internal ambient temperaturerises above 86 F (30 C) +/-10 F. The thermostat turns the heater back on at aninternal ambient temperature between 80 to 75 F.

4.3 Settings for Calculated Winding Temperature
Models equipped with the Aux CT input are supplied with a split core CT which issnapped over the secondary leads from the bushing CT. You may skip thissection if your model does not contain this feature. The winding hot spottemperature is calculated using the measured load current and top oiltemperature along with certain settings including the primary CT’s ratio, hot spotrise over top oil temperature at rated load, rated load current, winding rise timeconstant and if the transformer cooling is directed ODAF.
The ranges for these settings are:
Setting Setting Range Comments
CT Ratio 1:1 to 9999:1 Can be set to 0
Hot Spot Rise over Top Oil 0 to 99 C 18 to 22 C
Rated Load Current 0 to 65,535 A Enter top rating
Winding Rise Time Constant 0 to 999 minutes Minimum 32msec

4.5 Temperature Set Points
The TTC-1000 has four independent temperature set points per temperatureprobe and four calculated winding set points. Dual probe units with calculatedwinding temperature have a total of 12 temperature set points. Each set pointhas its own pick up and drop out temperatures. The pick up and drop outtemperature can be set at different temperatures and allows the controller to
operate as either an under or over temperature controller. The following twoequations describe how the controller reacts depending on the setting of the pickup and drop out temperature for liquid temperature probes:
If SPpn Pick UP > = SPpn Drop Out then operate as over temperature
If SPpn Pick UP < SPpn Drop Out then operate as under temperature
Where: p = Probe # (1 or 2) & n = Set point # (1, 2, 3, 4)
The equations for winding temperature pickup and drop temperatures are:
If WSPn Pick UP > = WSPn Drop Out then operate as over temperature
If WSPn Pick UP < WSPn Drop Out then operate as under temperature
Where: n = Set point # (1, 2, 3, 4)
The over temperature set point is ideal for handling the pickup of fans or pumpsas well as generating over temperature alarms and trip signals. The under
temperature feature is useful to block the operation of pumps at lowtemperatures.
Figure 4.1 and 4.2 show when the SP picks up and drops out for when thecontroller is configured to operate in the over and under temperature modesrespectively.

Once a set point has picked up, it will not drop out until the pre-programmedconditions are met. This feature is especially useful to allow the fans to continueto run until the top oil temperature drops to some lower temperature.
Each output can be controlled directly by a temperature set point. The flexibleprogrammable logic allows simple configuration to handle more complicatedtasks.
You will need to set pickup and drop out temperatures for each set point youwish to use. Once set, temperature set points take up to 16 seconds to takeaffect. Once you have established the pickup and drop out settings you are readyto assign the set points to a specific output. A set point will not pickup an outputuntil you assign it to OUT1, OUT2, OUT3, or OUT4.
When changing pickup or drop out temperature set points, the new value takeseffect the next time temperature data is updated which occurs every 16 seconds.However, once a SP is picked up, changing the pickup temperature to a higher (ifover temperature) or lower (if under temperature) value will not cause the SP todrop out. Once a temperature set point is picked up, the only way it can drop outis if the drop out condition is met.

4.5.1 Setting Liquid Pickup and Drop Out Temperatures
These settings are used to start a stage of cooling or indicate a high temperaturealarm for either probe 1 or probe 2 liquid temperatures. Models with a singleprobe channel measuring either Top Oil temperature or Winding temperaturethrough a heated well will use SP11, SP12, SP13 & SP14. Models with twoprobe channels where one probe measures Top Oil and the second probemeasures the winding temperature using a heated well may use SP11, SP12,SP13, SP14, SP21, SP22, SP23, SP24.

4.6 LTC Condition Monitoring
The TTC-1000 uses two mechanisms to detect tap changer problems. The first isbased on measuring the arithmetic difference between the LTC tank temperatureand top oil temperature and therefore is only available in dual temperature probeunits. The range of the LTCDIFF temperature is from –20 to +20 ºC. A timer canbe employed to supervise the pickup of the LTCDIFF set point to allow settingwith greater sensitivity and security. This method is particularly well suited todetect slowly evolving problems in the tap changer compartment from coking,polymerization of contacts, or loose connections.
PRGM SETTING 017WSP1PICKUP= 85C
PRGM SETTING 018WSP1DRPOUT= 80C
V4.41x, May 22, 200842
The second method uses a rate of rise algorithm that subtracts an initialLTCDIFF temperature from the LTCDIFF temperature at the end of a time perioddefined as LTCDIFF RATE. The difference between the initial temperature andfinal temperature is programmable from 0 to 40 ºC and is defined as LTCDIFFRISE. This method is particularly well suited to detected rapid increases intemperature possibly associated with an evolving arc in the tap changercompartment.
Both the LTCDIFF comparison against the LTCDIFF pickup temperature setpoint and the LTCDIFF rate of rise operate a single LTC point which is mappedinto the programmable logic of the TTC-1000.
NOTE: When using LTC condition monitoring, it is important to rememberto name one of the probes LTCDIFF. Evaluation of the LTC set point is notdone unless one of the probes is named LTCDIFF.

The TTC-1000 uses an LTC pickup timer settable from zero to 999 minutes tosupervise the LTC set point. The above example shows that the LTCDIFF setpoint does not pickup until after the timer is complete. If the differentialtemperature drops down below the pick up temperature while the timer is inprogress, the timer will reset. This timer allows the LTCDIFF set point to “ride”through daylight heating and hence permits a more sensitive setting. The aboveexample shows that the LTC set point does not drop out because the differencebetween the LTC Tank temperature and the Top Oil temperature does not dropdown to the LTCDIFF drop out temperature set point.
NOTE: The LTCDIFF temperature displayed is the calculated differential.The corresponding analog output tracks this differential temperature.
The LTCDIFF temperature is designed to read negative, because sometimes theLTC tank runs cooler than the top oil temperature. It is recommended that you
monitor the LTCDIFF temperature for a period of time to determine the normaloperating differential for the transformer. A good rule of thumb is to set theLTCDIFF pickup temperature from 3 to 7 degrees higher than the observedoperating differential. The sensitivity of this setting can be improved through theuse of the LTC pickup timer (LTCPUTMR) setting. The recommended setting forthe LTCPUTMR is between 360 to 480 minutes ( 6 to 8 hours ) to ignore theaffects of daylight heating on a lightly loaded transformer. The LTCPUTMR canbe set up to 999 minutes (16 hours 39 minutes).
To use this feature you must first make sure one of the two probes has beennamed LTCDIFF. Next, program the LTCDIFF PU (pickup) and LTCDIFF DO(drop out) temperatures. As mentioned earlier, it is a recommended that theLTCDIFF temperature be monitored to determine the transformer’s normaloperating point. Finally, the LTCPUTMR can be set once the transformers normaloperating condition is determined. Setting the LTCPUTMR to zero permits theLTCDIFF set point to pickup as soon as the LTCDIFF PU temperature is
reached. Setting the LTCPUTMR to some time other than zero will delay thepickup of the LTCDIFF set point as long as the LTCDIFF temperature is equal toor above the LTCDIFF PU temperature.
NOTE: The LTCPUTMR will not change while in progress. New settings willtake effect after the set point drops out or if the LTCDIFF temperature wereto drop below the LTCDIFF PU temperature while the timer is in progress.
Once you have established the pickup and drop out settings you are ready toassign the LTC set point to a specific output. This set point will not pickup anoutput until you assign it to OUT1, OUT2, OUT3, or OUT4.
V4.41x, May 22, 200844
NOTE:
1. In single probe versions, the LTCDIFF pickup and dropout settingsdisplay “N/A”.
2. Be careful to check that the LTCDIFF pickup and dropout set points arenever set to greater than 20 or less than –20. Erroneous operation of theLTCDIFF pickup or dropout will result if these set points are set beyondthe stated range.

zero. This method operates by comparing the measured rise between a start andstop period defined by parameter LTCDIFF RATE with the programmedparameter LTCDIFF RISE. If the measured rise is greater than or equal to theLTCDIFF RISE for a duration equal to or greater than the LTCDIFF RATE timer,an internal set point LTCDIFF R-R is picked up. If the LTCDIFF temperaturedecreases while the LTCDIFF RATE timer is in progress, the timer will reset andthe logic will wait for another LTCDIFF temperature increase before starting thetimer again. The recommended range for setting LTCDIFF Rise is 5 to 20 C.The LTCDIFF Rate can be set from 1 to 255 minutes.
NOTE: If the Rate of Rise setpoint has picked up, there is an extremely serious
problem in the tap changer and immediate attention is required. The rate of risefeature will remain picked up unless the unit is either powered down or it ismanually reset through the front panel.

4.7 Load Pickup Set Points
Load current is measured with an external split core Aux CT supplied withmodels equipped with this feature. The Aux CT is not intended for directexposure to the elements and should be installed within a NEMA 4 enclosure.
Units equipped with this feature have two load set points. Apply these set pointsto activate cooling earlier based on a sudden increase in load current due tonormal switching operations. Each set point has a load pickup timer settable from0 to 255 seconds. The timer operates to block inadvertent load set point pickupdue to fault conditions or inrush.
Each load set point has its own pickup and drop out current setting. Each settingis adjustable from 0 to 9.9 Amps in 0.1 Amp increments. These settings arebased on the primary current measured by the split core CT. Figure 4.4 illustratesthe operation of the Load Pickup Set Points.
V4.41x, May 22, 200848
Figure 4.5: Load Pickup Set Point Operation
The first case shows that the load current remains above the pickup set point forthe full duration of the load pickup timer. In this case the load pickup set point willbe picked up. The second case shows a transient load or external fault whereinthe load current drops below the pickup point soon after the timer starts. Thiscauses the timer to reset and the load pickup set point remains dropped out.
NOTE: When load current is present, it is important to set the load dropoutset point before the load pickup set point. If load pickup set point is setfirst, the load set point may be already picked up when this setting is madeand will not drop out.
The load set points can also be used to generate an alarm should the controllercommand cooling and the cooling system is drawing too little or too muchcurrent. For example, if the pickup current is set lower than the drop outtemperature, the set point operates as an under load detector. Conversely,setting the pickup point higher than the dropout point allows the set point tooperate as an overload detector. Setting one set point for under load and theother as overload permits detection of the cooling system’s load current “sweetspot”.

4.8 Optically Isolated Input Settings
The TTC-1000 may be optionally equipped with two optically isolated inputs.Each input contains a limiting resistor that allows these inputs to recognize awide range of input voltage of 38 to 160 VDC as being picked up. Inputs arescanned every 32 milliseconds. Contact chatter is debounced by requiring theinput be stable for two scans before the new state is recognized. Inputs may beassigned to any output using the programmable logic.
Each of the digital inputs can be set either as level active, LEVEL MODE orpositive edge active, PULSE MODE. For LEVEL MODE, the recognized state ofIN1 or IN2 follows the voltage applied to the input. There is a built-in 64millisecond debounce time on all low to high voltage transitions. There is no
debounce delay on high to low transitions. For PULSE, the recognized state ofthe input toggles every low to high voltage transition. High to Low transitions willnot change the recognized state of IN1 or IN2 in PULSE mode. There areseparate settings of LEVEL or PULSE for IN1 and IN2. Figure 4.5 illustrates theoperation of inputs set to LEVEL and Figure 4.6 illustrates the operation inputsset to PULSE.

4.9 Programmable Logic Settings
The TTC-1000 utilizes a simple scheme to control the four relay outputs. Eachoutput can be configured to be picked up or dropped out by assigning any of theavailable operands to a specific output. Table 4.1 illustrates the availableoperands.

4 Outputs can be assigned to either itself orany other output.
TIME (TIME1, TIME2, TIME3) 3 Settable pickup and dropout times. Eachsettable from 00:00 to 23:59
INPUT (IN1, IN2) 2 From optically isolated inputs, if equipped.
Table 4.1: Operands
An operand can only be assigned to a specific output and cannot be assigned toanother output as long as it is assigned. For example, SP11 cannot be assignedto OUT2 and OUT3; it can only be assigned to either OUT2 or OUT3. IN1 or IN2may be assigned like any other operand.
Any of the temperature set points or outputs can be inverted when assigned. Forexample inverting SP11 will cause SP11 to be recognized as true whenever it isde-asserted. Also, these specific operands can be either AND’ed () or OR’ed(+) to a specific output. In evaluating a specific output, the TTC-1000 groups allof the OR’ed terms together and all of the AND’ed terms together. As anexample by assigning SP11 + and SP21 + to OUT3 will result in the followingBoolean expression for OUT3:
OUT3 = SP11 + SP21
Assigning SP11 to OUT3 and SP21 and SP12 + to OUT3 will result in thefollowing Boolean expression:
OUT3 = SP12 SP11SP21
V4.41x, May 22, 200854
Note, the OR operator plays no roll in the evaluation of the above expression.
The TIME operands cannot be inverted and can only be OR’ed to the other termsassigned to the same output. As an example, if TIME2 is assigned to OUT3 inaddition to the operands SP1, SP2 and OUT1 as shown above, the Booleanexpression will be evaluated as:
OUT3 = (TIME2 + SP12) SP11SP21
TIME set points are evaluated as true at any time the real time clock date iswithin the specified pickup or drop out range of these set points.
NOTE: Do not use the inversion operator on individual set points whenremote control through DNP3.0 and fail-safe cooling control is desired. TheINVERT setting must be used on each output requiring fail-safe coolingcontrol when remote cooling control through DNP3.0 is required. The use
of the inversion operator on a set point will not be recognized by theremote control functions resulting in the cooling to be de-energized.
There are additional settings available that enhance the flexibility of theprogrammable logic. These functions include:
Output Timers for delaying pickup of the output relays.
Output Inversion that permits overall inversion of logic equations controllingoutputs. This is particularly useful for fail safe operation.
NOTE: Fail safe operation is strongly recommended. Fail safe operationensures that the cooling system picks up whenever the TTC-1000 becomesde-energized or encounters a failure.
Fail safe requires the output relay controlling the cooling stage to drop outinstead of picking up. This requires that each of the individual termsoperating an output to drop out and be AND’ed to every term or each termis OR’ed and the overall output invert used to drop out the relay. Pleaseremember to connect the contactor coil to the normally closed contact ofthe TTC-1000’s output relay.
4.9.1 Assigning Liquid Temperature Set Points
Liquid temperature set points must be assigned to a specific output to start astage of cooling, generate high temperature alarms, and generate hightemperature trips. For more complicated applications, these set points can beassigned to block a stage of cooling.
NOTE: DO NOT ASSIGN SP21, SP22, SP23, and SP24 IF ASSIGNING THELTCDIFF SET POINT.

4.9.7 Time Set Points
The time set points allow the user additional flexibility to activate events betweenspecific times. There are three time set points available.
Time set points are useful to exercise a bank of fans periodically. For example,the user can set the device to pick up an output at 03:00 hours and drop out at
PRGM SETTING 063! OUT1 TO OUT0
PRGM SETTING 063! OUT1 * TO OUT2
PRGM SETTING 063OUT1 + TO OUT0
V4.41x, May 22, 200863
04:00 hours. Time set points can be used in conjunction with the temperature setpoints to control an output. Therefore, when controlling a bank of fans for thepurpose of exercising them daily, it is necessary to OR (+) the temperature setpoint to the same output as the time set point. Time set points are by default,OR’ed to any other operand assigned to the same output.
A counter is provided to set the frequency at which the time set points willoperate. For example, setting the counter to 7 will operate the time set pointsevery 7th day.
Time set points use a 24 hour clock.
When using time set points in conjunction with temperature set points for thepurpose of picking up a cooling bank in fail-safe mode, both set points should beassigned as usual. To operate in fail-safe, apply the OUT INVERT to the specificoutput.
4.9.7.1 Time Set Point Settings

This will set the delay to pickup output 1 by 15 seconds. Consult the settingsheets to program the pickup timers for OUT2, OUT3, and OUT4.
4.9.9 Setting Output Invert
The output invert enhances the flexibility of the programmable logic by providingan overall output inversion for an entire logic equation. This is particularly usefulfor fail safe operation of the controller. Fail safe operation is highly recommendedas it allows your cooling system to be activated should the TTC-1000 becomede-energized or a device or temperature probe alarm is detected. Fail safeoperation is achieved by ensuring the output relay drops out when the necessaryset points are satisfied to command a stage of cooling. In fail safe it is vital toremember to wire the contactor controlling the fan bank between the commonand normally closed contact.
Programming from the front panel, press the or arrow button until the setting072 is displayed:

Press the YES button. The first character will flash. Use the or arrow buttonsto scroll between OFF and ON. Selecting ON will invoke the overall invertfunction. Press YES when you have made the correct selection.
INVERT OUT2, INVERT OUT3, and INVERT OUT4 can be selected by pressingthe arrow button and following the above procedure.
For programming from a PC just type the setting for output invert on the “Enter:”line as follows:
Enter:72/1
This will set OUT1 to INVERT. Type 0 for OUT1 not INVERT.
Consult the setting sheets to change INVERT OUT2, INVERT OUT3 or INVERTOUT4.
4.9.10 Application Examples
Any of the operands (temperature set points, load set points, inputs, time setpoints, LTCDIFF set points or the outputs themselves) can be assigned to OUT1,OUT2, OUT3, or OUT4. When assigning the temperature, LTCDIFF, and outputoperands you have the option of inversion (!) and either logically AND’ing (*) orOR’ing (+) the operand with other assigned operands to control a specific output.For example, you can assign two temperature set points with the AND (*)operator to OUT2. When both operands are picked up at the same time, theOUT2 picks up, after a settable pickup timer has timed out. If the OUT2 pickuptimer is set to zero, OUT2 will pickup in 32 milliseconds once both temperatureset points are picked up. OUT2 will remain picked up until either of the twotemperature set points drop out.
Using the inversion operator with a temperature set point programmed for overtemperature, is particularly useful when it is desirable to run the fans if the
controller becomes de-energized. When using the inversion operator for thispurpose, it is necessary to use the B contact of the output relay.
Time set points are also operands that can be assigned to OUT1, OUT2, OUT3or OUT4. However, time set points do not use the inversion (!) operator and arealways assigned with the OR (+) operator.
An INVERT setting is available for each output to allow the entire equation to beinverted. This is especially useful when using temperature and time set pointstogether in fail-safe.
V4.41x, May 22, 200867
NOTE: Do not use the inversion operator on individual set points whenremote control through DNP3.0 and fail-safe cooling control is desired. TheINVERT setting must be used on each output requiring fail-safe coolingcontrol when remote cooling control through DNP3.0 is required. The useof the inversion operator on a set point will not be recognized by theremote control functions resulting in the cooling to be de-energized.
The following are some application examples:
Commanding the cooling fans:
The simplest application is using an output to control a cooling bank. First,program the Pickup and Dropout temperature set point. Second, assign the setpoint to an output as follows:
Using the LCD: SPkl OUTn where kl= 11,12,13,14,21,22,23,24 and n=1,2,3,4
Using RS232: kk/0/0/n where k=Parameter # and n=1,2,3,4
The Boolean equation to control the same bank from two different set points isexpressed as follows:
OUTn = Temperature Set Pointkp1 + Temperature Set Pointk2l2
Using the LCD: SPkp1+ OUTn where kp1=11,12,13,14,21,22,23,24 and n=1,2,3,4
SPkp2+ OUTn where kp2=11,12,13,14,21,22,23,24 and n=1,2,3,4
Using RS232: kk1/0/1/n where kk1=Parameter # and n=1,2,3,4
Kk2/0/1/n where kk2=Parameter # and n=1,2,3,4
To control a bank in fail-safe, simply invert each setting as follows:
Using the LCD: !SPkl OUTn where kl= 11,12,13,14,21,22,23,24 and n=1,2,3,4
Using RS232: kk/1/0/n where k=Parameter # and n=1,2,3,4
NOTE: Do not use the inversion operator on individual set points whenremote control through DNP3.0 and fail-safe cooling control is desired. TheINVERT setting must be used on each output requiring fail-safe coolingcontrol when remote cooling control through DNP3.0 is required. The useof the inversion operator on a set point will not be recognized by theremote control functions resulting in the cooling becoming de-energized.
To control a bank using two set points in fail-safe:
Using the LCD: SPkp1+ OUTn where kp1=11,12,13,14,21,22,23,24 and n=1,2,3,4
SPkp2+ OUTn where kp2=11,12,13,14,21,22,23,24 and n=1,2,3,4
Using RS232: kk1/0/1/n where kk1=Parameter # and n=1,2,3,4
Kk2/0/1/n where kk2=Parameter # and n=1,2,3,4
V4.41x, May 22, 200868
Use the INVERT OUTn setting to cause the output relay to drop out when eithertemperature set point is achieved. The resulting Boolean equation is:
OUTn = !(Temperature Set Pointkp1 + Temperature Set Pointkp2)
Periodic exercise of cooling fans:
Use a time set point with the temperature set point, controlling the cooling fans,to exercise the fans on a daily basis. This is especially useful in areas where youmight be running the fans continuously during the cooler months of the year. TheBoolean equation to accomplish this task is:
OUTn = Time Set Pointm + Temperature Set Pointkl
Therefore, the cooling fans will come on when either the over temperaturecondition is achieved or the time of day is in between 02:00 to 03:00 hours.
To program the controller simply assign the time and temperature set points as
follows:
Using the LCD: 02:00 to 03:00 > OUTn
SPk + OUTn
Using RS232: mm/02:00/03:00/n where mm=parameter # and n=1,2,3,4
Kk/0/1/n where k=parameter # and n=1,2,3, 4
To operate the output in fail-safe, just invert the expression using the outputINVERT setting. Remember to use the B contact of the output relay.
Cooling Fan Alarm:
This example shows how to generate an alarm when cooling is commanded butthe measured current as sensed by the Aux CT is not within a specified range.The Boolean equation for this function is expressed as:
OUTn1 = (Load Set Pointm1 + Load Set Pointm2) OUTn2
First you must program Load Set Pointm1 for an underload condition, that is thepickup current less than dropout, and Load Set Pointm2 for overload. Once theseare programmed the two load set points must be assigned as OR to OUTn1 asfollows:
Using the LCD: LSPm1+ OUTn1 where m1=1,2 and n1=1,2,3,4
LSPm2+ OUTn1 where m2=1,2 and n1=1,2,3,4
Using RS232: mm1/0/1/n1 where mm1=Parameter # and n1=1,2,3,4
mm2/0/1/n1 where mm2=Parameter # and n1=1,2,3,4
Then assign the output, OUTn2, commanding cooling to OUTn1 as follows:
Using the LCD: OUTn2 OUTn1 where n1=1,2,3,4 and n2=1,2,3,4
Using RS232: n1/0/0/n2 where n1=Parameter # and n2=1,2,3,4

4.10 Setting Output Control With Alarm
The TTC-1000 monitors two critical conditions: processor (DEVICE) andtemperature (TPROBE) and allows the user to control how each output reactswhen an alarm occurs. A DEVICE alarm occurs anytime the microprocessordetects a failure in any of the peripheral hardware including the non-volatile E2
memory, the real time clock, analog outputs, corruption of stored data and powersupply brown out.
The TPROBE alarm is generated anytime the processor is unable to obtainreliable temperature information. This failure can be due to a discontinuity in theleads connected to the temperature probe or with any of the internal circuitryassociated with the analog to digital conversion process. All temperature setpoint evaluations are suspended until the alarm condition is cleared.
The TTC-1000 allows you to program how an output will react whenever there is
a DEVICE or TPROBE alarm. There are three (3) ways an output can reactwhenever there is a DEVICE or TPROBE alarm:
1. Unchanged (UNCHG): the output remains as it was prior to thealarm.
2. Picked Up (PCKUP): the output picks up when alarm occurs.
3. Supervised (SUPVS): the output drops out when alarm occurs.
The TTC-1000 output control default is UNCHG for each output.
The user should decide how they wish each output to operate whenever there iseither a DEVICE or TPROBE alarm. For example if OUT1 and OUT2 control twoseparate banks of fans, it might be desirable to have OUT1 and OUT2 pickup assoon as a DEVICE or TPROBE alarm occur. This insures that the fans arerunning even though there might be a device or temperature probe failure.
NOTE: It is strongly recommended to set output control to supervised(SUPVS) for all outputs controlling cooling fans in fail-safe mode.
However, if OUT3 is used for a trip signal, it may be desirable to use the DEVICEor TPROBE alarm to supervise OUT3. This will insure that a trip signal is blockedwhenever a DEVICE or TPROBE alarms occur.
Also, if OUT4 is used for a high temperature alarm, it may be desirable for OUT4to remain unchanged if a DEVICE or TPROBE alarm occurs. This will insure thata high temperature alarm continues to be reported.
Programming from the front panel, press the or arrow button until the setting038 is displayed:
PRGM SETTING 038OUT1UNCHGw/ALRM
V4.41x, May 22, 200870
Press the YES button. The first character will flash. Use the or arrow buttonsto scroll between PCKUP, SUPVS or UNCHG.
Press YES when you have made the correct selection.
For programming from a PC just type the setting for Output Control with Alarm onthe “Enter:” line as follows:
Enter:38/2
This will set OUT1 supervised with a Device or Temperature Probe Alarm. Type1 to pickup OUT1 with a Device or Temperature Probe Alarm, or 0 to leave theoutput unchanged with a Device or Temperature Probe Alarm.
Consult the setting sheets to change output control for OUT2, OUT3, and OUT4.
4.11 Alternate Fan Banks
The TTC-1000 can be programmed to alternate the energization between twooutputs. This feature is particularly useful when it is desirable to insure a fanbank is regularly exercised.
You can choose between seven (7) alternate options:
1. Disabled (DSABL)
2. Alternate between OUT1 and OUT2 (1 – 2)
3. Alternate between OUT1 and OUT3 (1 – 3)
4. Alternate between OUT1 and OUT4 (1 – 4)
5. Alternate between OUT2 and OUT3 (2 – 3)
6. Alternate between OUT2 and OUT4 (2 – 4)
7. Alternate between OUT3 and OUT4 (3 – 4)
As an example, if Alternate between OUT1 and OUT4 is selected, the first timeOUT1 picks up, the output relay associated with OUT1 will pick up. If OUT4 picksup while OUT1 is picked up, the relay associated with OUT4 will pick up.
Once both OUT1 and OUT4 drop out, the next time OUT1 picks up the relayassociated with OUT4 will pick up. If at sometime in the future OUT4 picks upwhen OUT1 is already picked up, the relay associated with OUT1 will pick up.The cycle repeats when both OUT1 and OUT4 have dropped out.

For programming from a PC just type the setting for ALTERNATE on the “Enter:”line as follows:
Enter:83/1
This will set ALTERNATE=1-2. Type 2 to ALTERNATE=1-3, 3 toALTERNATE=1-4, 4 to ALTERNATE=2-3, 5 to ALTERNATE=2-4, or 6 toALTERNATE=3-4. Type 0 to disable alternate.
4.12 Auto and Manual Control
The TTC-1000 supports direct manual control of any output relay directly fromthe front panel. When commanded ON, the relay picks up and commanded OFFthe relay drops out. Manual control is important for two reasons. First, it gives theuser a simple method to test the connections to the output relays whencommissioning the unit. Second, it gives the user the ability to manually overrideboth automatic or remote control should the operator desires to commandcooling on a continuous basis. It can also be used to prevent an output frompicking up.
Manual mode can be exerted by communicating through the RS-232 interface,but it is impossible to control the output relay using this method. This settingshould only be used when it is desired to block remote control of a specific outputrelay. Also, the TTC-1000 will leave the output relay whatever state it happenedto be at the time manual control is exerted through the RS-232 interface.
The TTC-1000 will cause the Device Alarm contacts to pick up when an output isput into the manual mode. In addition the ALARM LED on the front panel willilluminate. The user can block this alarm by using the manual mode alarmdisable setting shown in Section 4.13.3.

Enter:37/1
This will set OUT1 to MANUAL OFF. Type 0 to return OUT1 to AUTO.
Consult the setting sheets to change AUTO to MANUAL for OUT2, OUT3, andOUT4.
4.13 Setting Control of Unit Alarm
The single form B relay is utilized to provide a dry contact closure for alarmconditions. While the unit is energized, the alarm relay is energized. This allowsthe unit to provide an alarm should the device lose DC power or becomes de-energized.
The TTC-1000 monitors five conditions: Processor (DEVICE), Temperature(TPROBE), Manual Mode (MANUAL), Winding (WNDCKT), DNP3.0Communications (CPROC). The TTC-1000 allows the user to enable or disableall of the alarm conditions, except the DNP3.0 Communications (CPROC),through programming.

5 TELEMETRY OPTIONS
This section will discuss the various telemetry options available, their use andany relevant settings. The TTC-1000 can be optionally equipped with currentloop outputs and a RS-485 DNP3.0 communications interface. All TTC-1000’scome equipped with a 9 pin DB-9 connector for RS-232 ASCII communications.Temperature information can be retrieved through the RS-232 interface.
5.1 Analog Outputs
The TTC-1000 is available with two analog outputs configured as current loops.The source for each analog output can be selected from probe 1 (P1), probe 2(P2), or calculated winding temperature. The analog output is designed tooperate with a series resistance of 9,500 Ohms when set to 0 to 1 mA or 450Ohms when set to 4 to 20 mA. The third analog output is configured to supply 0to 1 mA and cannot be switched to operate in the range of 4-20 mA.
The analog outputs are connected to terminal block TB2 on all panel mount units.NEMA units with serial letter suffix ‘B’ contain TB4 for connections to the analogoutputs. All other NEMA units utilize TB2. The terminal marked + is the currentsource output. The connection marked – is the current transmitter’s return and istied directly to the chassis ground.
NOTE: Connect to the analog outputs through shielded cable. Connect thedrain wire of the shield to one of the ground stud on the rear of the TTC-1000 or inside the NEMA 4 enclosure. Twisted pair cable is recommended.
The analog outputs A1 and A2 can be programmed for 0 to 1 mA or 4 to 20 mA.Both analog outputs are identically programmed.
The scaling of the analog output varies depending on what is being measured.The following table illustrates the scaling dependent on range and the quantitymeasured and whether negative temperature scaling is enabled:
Probe Min @ -35 Min @ 0 Max
0 to 1 mA Range:
P1 or P2 0 mA @ -35 ºC 0 mA @ 0 ºC 1 mA @ 160 ºC
CALC. WINDING 0 mA @ -35 ºC 0 mA @ 0 ºC 1 mA @ 180 ºC
LTCDIFF Not Applicable 0 mA @ -20 ºC 1 mA @ +20 ºC
4 to 20 mA Range:
P1 or P2 4 mA @ -35 ºC 4 mA @ 0 ºC 20 mA @ 160 ºC
CALC. WINDING 4 mA @ -35 ºC 4 mA @ 0 ºC 20 mA @ 180 ºC
LTCDIFF Not Applicable 4 mA @ -20 ºC 20 mA @ +20 ºC
V4.41x, May 22, 200880
Upon initialization, the DAC is set to zero, if 0 to 1 mA or offset to drive 4 mA, ifset for 4 to 20 mA. During the initialization process, the processor looks to see ifthe DAC is installed. If installed, the DAC will be updated every 16 seconds whennew temperature data is available.
Should the user select a new range, the output will not change range until newtemperature data is available.
The relationship of the analog output differs depending on what the probe ismeasuring. For top oil, winding, and ambient temperatures the relationshipbetween output current and temperature is as follows:
Range 0 to 1mA with normal scaling:
For measurements from P1 or P2: Current = Temperature/160
For calculated winding temperature:Current = Temperature/180
Range 4 to 20mA with normal scaling:
For measurements from P1 or P2: Current = 0.1 x Temperature +4
For calculated winding temperature:Current = 0.089 x Temperature + 4
Range 0 to 1mA with negative scaling:
For measurements from P1 or P2: Current = Temperature/195
For calculated winding temperature:Current = Temperature/215
Range 4 to 20mA with negative scaling:
For measurements from P1 or P2: Current = 0.08205 x Temperature +6.872
For calculated winding temperature: Current = 0.07442 x Temperature + 6.605
For LTCDIFF the relationship is as follows:
Range 0 to 1mA:
0.540eTemperaturCurrent
Range 4 to 20mA:
12eTemperatur0.4Current
5.1.1 Setting the Analog Output Range
The analog output range for both A1 and A2 can be switched from 0 – 1 mA to 4– 20 mA. The range of the third analog output is fixed at 0 – 1 mA and cannot bechanged. To change this setting, enter PROGRAM mode from the front panel asdiscussed in Section 4.1.

The default scaling of analog outputs for all but LTCDIFF is from zero degrees.However, if operating in cold climates, it may be necessary to scale the analogoutputs from –35 ºC for all temperatures except LTCDIFF.
To change this setting, enter PROGRAM mode from the front panel as discussedin Section 4.1. To set the analog source from the front panel, press the orarrow button until the setting 103 is displayed:
Press the YES button. The first character will flash. Use the or arrow buttonsto scroll between YES and NO.
Press YES when you have made the correct selection.
For programming from a PC, enter PROGRAM through the main menu asdiscussed in Section 4.2. Once in PROGRAM, type the setting for the NEGANALGOUT SCALING on the “Enter:” line as follows:
Enter:103/1
This will change the scaling from normal to negative. Type 0 to change back tonormal scaling.
5.2 DNP3.0
Units equipped with the optional DNP3.0 communications interface contain aplug-in Communications Processor module. The module contains a separatemicroprocessor to handle all overhead functions associated with the DNP3.0protocol without affecting operation of the transformer cooling control andmonitoring. The module contains either a half duplex, full duplex isolated RS-485,multi-mode fiber optic asynchronous communications interface capable of
PRGM SETTING 103NEG ANALGOUT=NO
V4.41x, May 22, 200883
supporting multi-drop topologies. RS-485 interfaces differ from RS-232 in thatRS-485 uses a differential receiver and transmitter pair. This permits RS-485links to send and receive data over much greater distances as long as somesimple rules are followed. See Sections 3.7.3 and 3.7.4 for connections andjumper settings.
After making the proper connections to the TTC-1000, there are only two settingsthat need to be made: Node Address and Baud Rate. Node Addresses can beany number from 0 to 65535. Please consult the DNP3.0 reference materials assome higher order addresses are reserved for broadcast messages.
Baud Rates can be set to either 1200, 2400, 9600 or 19200. It is recommendedthat both Node Address and Baud Rate settings be made before attempting tocommunicate, however these settings can be changed “on-the-fly” withoutpowering down the TTC-1000.
The TTC-1000 implements DNP3.0 Level 1 communications. This includes Class0 polls (Object 60 Variation 1) of analog and binary output points. The TTC-1000supports Object 1 Variation 2 binary outputs. Binary outputs include alltemperature and load set points along with the state of each output relay.Because Variation 2 is supported, the TTC-1000 communicates whether or notan output relay is under manual control by exerting the “forced” status bit forthese points only. The “forced” status bit is located in bit 4 of each binary outputoctet transmitted to the Master. For Analog Outputs, the TTC-1000 supportsObject 30 Variation 4. These are 16 bit signed analog quantities without status.Included in the Analog Output points are all temperatures equipped plus loaddata if available. Also, the TTC-1000 uses two points to identify whether or notthe probe is measuring Top Oil, Heated Well, LTC Differential or Ambienttemperature. This is particularly useful for dual probe units. It is noted that Object1 Variation 2 and Object 30 Variation 4 points cannot be read individually andcan only be read by a Class 0 poll.
In addition, the TTC-1000 supports the remote control of the four output relays.The TTC-1000 supports both direct control (Object 10 Variation 0) and SelectBefore Operate control (Object 12 Variation 1). The TTC-1000 permits the userto command an output relay to pickup. It cannot be used to dropout an outputrelay. If the Binary Input point is turned off, it merely returns the device to localautomatic control. Once the unit accepts the remote control command, the“remote forced” bit will become a logic “1”. The “remote forced” bit will remain alogic “1” until that point is dropped out by the DNP Master.
Remote control can be blocked through the use of the REMOTE BLK setting.Enabling this setting will prevent all output points from picking up through remotecontrol. Also, enabling the REMOTE BLK setting after an output has beencommanded to remotely pickup but before remote control is returned to localcontrol, will cause all output points to revert back to local automatic control. The“remote forced” bit will remain logic “1” until the point is returned back to local
V4.41x, May 22, 200884
automatic control. Remote control will be immediately re-enabled once theREMOTE BLK setting is disabled.
In addition, local manual control overrides remote control. The user shouldobserve the status of the “local forced” bit in the appropriate Binary Output point,as noted above, before attempting to exert control as the TTC-1000 willremember that the bit has been exerted even though the TTC-1000 is in ManualMode. Once an output is released from Manual Mode, the output will eitherreturn to automatic or remote control. If the point had been commandedremotely, the output will pickup as soon as the field personnel remove localmanual control. This could result in an undesired operation of the specific outputrelay. Users of remote control should always remember to turn off a Binary Inputonce they have turned it on to insure a return to local automatic control. This iswhy Users should observe the “local forced” and “remote forced” bits.
To maintain compatibility with Fail-Safe operation of the cooling system, remote
commanding of cooling operates in conjunction with the INVERT setting for eachoutput. For example, if the INVERT bit is set for OUT1, then the OUT1 relay willdrop out. This is an important point to remember when setting the programmablelogic as Fail-Safe cooling will not be observed under remote control if the userimplements Fail-Safe cooling by assigning a set point using the inversionoperator.
Finally, the user should not expect instantaneous report of updated temperatureand status from the TTC-1000. The use of a separate CommunicationsProcessor does not guarantee instantaneous reporting of data. The philosophy ofimplementation is that the top priority of the Main microprocessor is for controland monitoring and the Communications Processor is to receive potentially high-speed request messages from the DNP Master and to respond to these requestswithout delay. While higher polling rates are possible, it is highly recommendedthat the polling rate be between 1,000 to 10,000 milliseconds, but should be nofaster than 500 milliseconds.
Please refer to the DNP3.0 Profile Document in Section 14 for additional detailsand specific definitions of all points supported.

data, no parity, and one stop bit. We have verified operation of the interface withProcomm Plus, HyperTerminal and Windows Terminal 3.1. It is recommendedthat the terminal emulation be set for either ANSI or TTY. The pin out of this portis designed to use a 9 pin female to 9 pin male null modem cable.
The TTC-1000 permits remote reporting of temperature or resetting of the time ofday by sending a forward slash ‘/’ followed by either the characters T(temperature) or R (reset) followed by an ASCII carriage return character (13Hex).
Sending the string: /T causes the TTC-1000 to reply with the ambienttemperature. The temperature reported will be in the units (Celsius or Fahrenheit)that the TTC-1000 was programmed to display temperature. Units are nottransmitted. It is noted that the command /T is echoed back to the host computeralong with the measured temperature without a carriage return character. Forexample, if the TTC-1000 is measuring an ambient temperature of 68 ºF, the
exact format of the reply for a single probe unit is:
68
For dual probe versions, the reply is:
68/93
Where the first temperature is probe #1 and the second is probe #2.
Sending the string /S causes the TTC-1000 to report the status of the outputrelays (OUT1, OUT2, OUT3 and OUT4) and alarm type (DEVICE, TPROBE, andWDGCKT) as a series of ASCII character ‘0’ for off and ASCII character ‘1’ foron. The string reported is as follows:
OUT1/OUT2/OUT3/OUT4/ALRM_DEVICE/ALRM_TPROBE/ALRM_WNDCKT
A typical response to the /S command is:
1/0/0/0/0/0/0
This string indicates that OUT1 is picked up and OUT2, OUT3, OUT4,ALRM_TPROBE, ALRM_TPROBE, and ALRM_WNDCKT are dropped out.
Sending the string /R causes the TTC-1000 to reset the real time clock to00:00:00 hours. The date is not changed. It is noted that the characters /R areechoed back to the host computer.

9.2 Download Setting Files
Download settings transfers the binary setting file or *.csv file on your PC to theTTC-1000 connected through the RS232 communications port. The TTC-1000uses the XMODEM protocol which is supported by HyperTerminal andHyperAccess as well as other terminal emulation programs. Checksum errorchecking is employed.
NOTE: Be careful that the file sent is NOT a text file and is a valid settingsfile. Transferring a text version of a settings file into the TTC-1000 willcause the settings to be overwritten by text characters causingunpredictable behavior. To recover from this situation, download a knowngood settings file to overwrite the text. The master password 0905 will needto be used to regain access. Should this not work, please contact us forassistance.
NOTE: Download may be terminated prior to the transfer by pressing anykey on the keyboard
NOTE: The TTC-1000 will suspend all measurements and calculations oncedownloading is selected. The outputs will also be blocked during this time.The TTC-1000 transfers the new settings to a buffer register and willtransfer the settings to E2 memory only after the checksum test is passed.

10 DATA LOGGING
Data logging permits storage of time stamped temperature and load data. Theuser has the ability to change the time base used for time stamping from 1 to9999 seconds. Setting the time base to zero erases the log and prevents recordsfrom being recorded. The user can select which points to record. Points whichcan be recorded include probe P1’s temperature, P2’s temperature, calculatedwinding temperature, and load. Once the log is full, the oldest records are overwritten with the newest records. Since the records are stored in non-volatilememory, records are never lost even in the event of a power interruption.
10.1 Data Storage
There are 32,512 bytes available for storage of data records. A byte is defined asan 8 bit quantity. Each record is time stamped at an interval defined as the TimeBase. A data record is defined as a set of data points. Data points can include
probe P1’s temperature, P2’s temperature, calculated winding temperature, andload. All temperatures are stored as a single byte. Load is stored as a two bytequantity. There are two additional bytes per record to assist the firmware instoring and retrieving the data log. A record can be anywhere from 3 bytes to 7bytes in length. The following table summarizes the available data points and themaximum number of records that can be stored:
Points Recorded Bytes/Record Max Records
P1, or P2, or Calculated Winding 3 10,837
Any two temperatures 4 8,128
Any one temperature and Load 5 6,502
P1 and P2 and Calculated Winding 6 5,418
Any two temperatures and Load 6 5,418
All three temperatures and Load 7 4,644
Table 10. 1: Maximum Records
After selecting the data points to log, it is simple to figure out the length of timedata can be recorded. For example if 30 minutes time stamping is required, TimeBase=1800, and all four points (P1, P2, Winding & Load) are required, themaximum time that data can be recorded in days is equal to 4,644 divided by 48records per day or 96 days. This can be extended to up to 1254 days if only onetemperature is recorded every 9999 seconds or ~2.75 hours. Practicallyspeaking, a temperature and load will be logged every hour or 3600 seconds. Inthis case the log will hold 270 days of data.
There is one limitation, in the event that power is interrupted, the time stamp isstored as a data record. Time stamp records consume a total of 8 bytes. This is a
V4.41x, May 22, 2008104
non-factor if power is never interrupted, but if the device is AC powered, it couldreduce the number of records by a small amount.
10.2 Data Points
Data recorded can be selected for logging. For P1 or P2, the data recorded takesthe name chosen for the specific temperature probe. If P1 or P2 is chosen asLTCDIFF, the data recorded is the differential between the LTC tank temperatureand the Top Oil probe. All other temperature points are recorded as the absolutevalue of the measured temperature.
The load current reported is the average or demand logged for the periodbetween samples. If a Time Base of 15 minutes is selected, the load current isthe average value over 15 minutes. For Time Base settings less than 16seconds, the load current reported will be the actual load current.
10.3 Setting the Time Base
Time Base can be entered from 0 to 9999 seconds. Setting the Time Base tozero will reset the log and no records will be logged. Changing the Time Base willerase the log and commence recording with the new Time Base.
To change this setting, enter PROGRAM mode from the front panel as discussedin Section 4.1. To set the time base from the front panel, press the or arrowbutton until the setting 090 is displayed:
Press the YES button. The first digit will flash. Use the or arrow buttons toscroll through the digits 0 – 9. Use the orbuttons to scroll between thedigits. The currently active digit will flash. Press YES after you have entered allfour digits.

Enter:90/3600
This will set the Time Base to 3600 seconds.
10.4 Selecting Data Points
Any or all of the data points can be selected for logging. Change the number ofpoints or the points recorded will erase the log. If no points are selected the logwill be erased and no data logged. There are four points that can be added to the
