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 panelmount units (Figure 3.4a) power is connected to terminals 1 and 2 of barrier styleterminal block TB1. On NEMA units (Figure 3.4b) power is connected toterminals 1 and 2 on TB-3. The TTC-1000 is not sensitive to polarity because ituses a bridge rectifier on the power input. This feature eliminates the risk ofdamage due to the reversal of power applied to this input.

Figure 3.4: Power Connections

NOTE:

1. It is strongly recommended that the chassis of the panel mount unit orNEMA 4 enclosure be bonded to ground. It is especially important toground 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 is installed on the AC mains feeding theunit.

WARNING:

NEVER CONNECT POWER TO TERMINALS DESIGNATED FOR THE AUXCT. SERIOUS DAMAGE WILL OCCUR.

3.3 Temperature Probes

The TTC-1000 can be equipped with up to three probes. Universal thermowellprobe types TTC-PROBE-01 and TTC-PROBE-11 are each provided with three

thermometer well adapter fittings: 7/8-UNF (ANSI/IEEE C57 thermometer well),½-NPT and ¾-NPT and three probe sleeves: 0.481, 0.625 and 0.675 OD.

Temperature probes are interchangeable and do not require calibration. Thetemperature probes and measurement circuitry are intrinsically accurate to thestated accuracy specification. The probe leads are connected to a plug gablecompression style terminal block. A terminal block is supplied with each unit andplugs into TB2.

3.3.1 TTC-PROBE-01 Installation

Probe type TTC-PROBE-01 is provided with a strain relief that seals thethermometer well and holds the probe from pulling out of the well. Figure 3.5shows the outline drawing for this probe type.

Figure 3.5: PROBE-01 Installation

To install the probe into the thermo well:

1. Select the appropriate thermo well adapter fitting and either wrap the malethreads with Teflon tape or coat with suitable pipe dope compound. Oncethe male threads are prepared, thread the adapter fittings into the thermowell.

2. If the probe well’s ID is greater than 0.390 select the appropriate probesleeve and slide over the probe. Tighten the set screw with theaccompanying Allen Key.

3. Slide the probe into the thermo well.

4. Ensure that the snap elbow fitting is fully open. Apply Teflon tape to themale threads of the snap elbow fitting. Thread the snap elbow into thefemale threads of the thermo well adapter fitting.

• 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 3.7.

Figure 3.7: 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 3.8.

The resistance from the white to black probe leads is 1000 ohms and from whiteto red leads is 1000 ohms at 23° C and increases as a function of temperature.Figure 3.10 shows the probe connections for NEMA units.

Figure 3.10: Probe Connections

NOTE:

For dual or three probe units, you must use all temperature probes forproper operation. The unit will continuously alarm if you fail to use bothprobes.

If an addtional probe is unavailable, you can use two 1,000 ohm resistors.One end of one resistor to REF, the end of the second resistor to TMP. Tiethe loose 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 3.11.

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 halvesclosed. Select a CT secondary tap ensuring that it is either shorted or already inuse. It is recommended that B phase CT be used for this purpose. Wrap the wirewith several layers of electrical tape and apply the split core CT over the wire andsnap it closed. It is highly recommended that a cable tie be applied under thesplit core CT to keep it from sliding down against the lug. Figure 3.12 illustratesthe assembly of the split core CT onto the bushing CT secondary.

Configure these contactsfor cooling control, high temperature alarms, or LTC condition alarm.Programming these contacts 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.

the 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 3.16a illustrates the connections to panel mount models and Figure 3.16billustrates connections to NEMA 4 models. Three probe units bring the NOcontact out of the Alarm relay on TB2-3.

Figure 3.16: 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.

3.7.1 RS-232 Terminal Connections

Connection to this interface is through the front panel mounted DB-9 connector.When connecting to a standard RS-232 port in a PC, either desktop or laptop,use a 9 pin female to 9 pin male null modem cable. The following table lists thepin connections to the DB-9 connector.

3.7.2 Analog Outputs

The three probe version of the TTC-1000 is not available with analog outputs atthis time.

3.7.3 RS-485 for DNP3.0 Communications

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 standard module used in panel mount and NEMA 4 modelscontains a half duplex RS-485 asynchronous communications interface capableof supporting multi-drop topologies with a single shielded twisted pair cable.NEMA 4 models can be optionally equipped with a four wire isolated RS-485interface. RS-485 interfaces differ from RS-232 in that RS-485 uses a differentialreceiver and transmitter pair. This permits RS-485 links to send and receive dataover much greater distances as long as some simple rules are followed.

A jumper, J2, can be selectively installed if the TTC-1000 is either the first or lastdevice on the two wire communications bus. Figure 3.18 illustrates the location ofJ2 on the Communications Processor Module. Jumper J2 must be installed if theTTC-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.

V1.00, August 30, 200423

Figure 3.18: Location of J2 RS-485 Bus Termination Jumper

NOTE: For panel mount versions, the unit contains the jumper but it is notinstalled. To install jumper J2, the unit must be disassembled. The RelayBoard must be removed to gain access to the Communications ProcessorModule. J2 is located on the Communications Processor Module. It is notedthat an 120 ohm resistor (a carbon or metal film resistor recommended)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 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 connectedin 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 3.19a and 3.19b illustrates connectionsto panel mount and NEMA 4 models. Figure 3.20 illustrates connection to thefour wire interface on NEMA 4 models.

3.8 Optically Isolated Inputs

Models equipped with inputs contain two optically isolated inputs, IN1 and IN2.These inputs must be wetted from an external power supply between 38 and 160VDC. Connections are made through plug-in terminal block TB1. These opticallyisolated inputs may be used by the programmable logic to control or superviseany output. These inputs can also be used to communicate status informationfrom devices such as the liquid level alarm or sudden pressure over DNP3.0. IN1

3.9 Heater Connections

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 FOA or FOW.

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

m Constant 0.8 or 1

The steady state winding temperature is calculated based on the followingequation1:

Where:

TWindingU = Ultimate calculated winding temperature

TTopOil = Measured Top Oil temperature

It is noted that the Hot Spot Rise over Top Oil at rated load is not alwaysavailable. In this case we recommend subtracting the Top Oil Rise from theaverage conductor rise at rated load and add between 18 to 22 ºC to thedifference to obtain the hot spot rise over top oil at rated load.

To accommodate the transient affect of changing load current, the windingtemperature can be estimated at any point in time by entering the winding timeconstant. Therefore, the displayed winding temperature is calculated as follows:

Where:

TWinding(t) = Winding temperature at time t

TWindingU = Ultimate winding temperature using equation [1] above

TWindingI = Initial winding temperature using equation [1] above

τW = Winding time constant in minutes

TTopOil = Measured Top Oil temperature

Because data to calculate τ W may not be available, the recommended setting forthe winding time constant is between 5 to 10 minutes.

4.3.1 CT RATIO

The CT RATIO is the CT ratio of the bushing CT which the split core CT isapplied to. The CT ratio must be relative to 1. Therefore, if the CT ratio is 240:5the CT ratio to enter is 48.

Programming from the front panel, press the %%%% arrow button until the setting 025is displayed:

Press the YES button. The first digit will flash. Use the %%%% or &&&&arrow buttons toscroll through the digits 0 – 9. Use the '''' or ((((buttons to scroll between thedigits. Each digit moved to will flash. Press YES after you have entered all fourdigits.

Enter:92/48)

PRGM SETTING 025CT RATIO=0000

V1.00, August 30, 200431

4.3.2 Rated Load

The Rated Load setting is the top name plate rating in Amps. If the nameplateindicates ratings of 1000/1200/1400, use 1400 as the rated load. On sometransformers the nameplate might only list the rating in MVA. In this case you willneed to divide the top MVA rating by the voltage of winding monitored with theCT. The rated load is calculated as follows:

Rated Load = MVA / (Voltage x 1.732)


Press the YES button. The first digit will flash. Use the %%%% or &&&&arrow buttons toscroll through the digits 0 – 9. Use the '''' or ((((buttons to scroll between thedigits. Each digit moved to will flash. Press YES after you have entered all digits.

For programming from a PC just type the Rated Load on the “Enter:” line asfollows:

Enter:93/1473)

This will program the Rated Load to 1473 Amps.

4.3.3 Hot Spot Rise over Top Oil

The Hot Spot Rise over Top Oil setting is either a number that can be obtainedfrom the transformer manufacturer, deduced from heat run data or estimated inthe range of 18 to 22 º C.



For programming from a PC just type the Winding Rise @ Rated Load on the“Enter:” line as follows:

PRGM SETTING 027WINDINGRISE=00 ºC

PRGM SETTING 026RATED LOAD=00000

V1.00, August 30, 200432

Enter:94/20)

This will program the hot spot rise to 20 degrees Celsius.

4.3.4 Winding Rise Time Constant

The Winding Rise Time Constant is the amount of time, in minutes, for thewinding hot spot temperature to reach 67 percent of its final value. A number offactors including the volume and type of oil used and the mass of the transformerare factors that influence this setting. Because calculating this value iscumbersome, we recommend a setting from 5 to 10 minutes.



For programming from a PC just type the Winding TC on the “Enter:” line asfollows:

Enter:95/7)

This will program the winding rise time constant to 7 minutes.

4.3.5 Calculated Winding Exponent Setting

The m exponent used to calculate winding temperature can be modified. The twochoices are 0.8 for non-directed FOA type transformers and 1.0 for directed FOAor FOW types.


Press the YES button. The first character will flash. Use the %%%% or &&&&arrow buttonsto scroll between NO and YES. Press YES when you have made the correctselection.

4.3.6 Checking Winding Temperature

A built in WNDGCAL test function is provided to verify proper operation of thecalculated winding temperature function. All settings described in Sections 4.3.1through 4.3.5 must be made before performing this check. To verify correctoperation of calculated winding temperature:

• Connect the split core CT to the unit as described in Section 3.3.

• Loop a conductor from a suitable test set capable of generating 5.0 AmpsRMS through the window of the split core CT.

• Press the %%%% arrow button until the display reads:

Record this number.

• Press the &&&&arrow button once. The display will read:

• Wait until the display scrolls to winding temperature:

• Check the measured winding temperature against the WNDGCAL value. Ifthe winding temperature is not within three degrees, re-check the connectionsto the split core CT and the current passing through the CT’s primary.

4.5 Temperature Set Points

The TTC-1000 has four independent temperature set points per temperatureprobe and four calculated winding set points. Three probe units with calculatedwinding temperature have a total of 16 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 tooperate 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, 2 or 3) & n = Set point # (1, 2, 3, 4)

The equation 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 undertemperature 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.

Figure 4.2: Under Temp Operation

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.

1. When changing pickup or drop out temperature set points, the newvalue takes effect the next time temperature data is updated whichoccurs every 16 seconds. However, once a SP is picked up, changingthe pickup temperature to a higher (if over temperature) or lower (ifunder temperature) value will not cause the SP to drop out. Once atemperature set point is picked up, the only way it can drop out is if thedrop out condition is met.

3. WSP1, WSP2, WSP3, WSP4 drop out and pick up are settable in modelswithout the calculated winding feature, but do not have any function.

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, SP31, SP32, SP33, SP34.

This will program WSP1 pickup to 85°C.

4.6 LTC Condition Monitoring

The TTC-1000 has up to two set points that the user can employ for LTCconditioning monitoring. The LTC differential, or LTCDIFF, is the mathematicaldifference between the LTC tank and top oil temperatures and therefore is onlyavailable in dual temperature probe units. The range of the LTCDIFF is from –20to +20 ºC. A timer can be employed to supervise the pickup of the LTCDIFF setpoint to allow setting with greater sensitivity and security.

NOTE: When using LTC condition monitoring, it is important to rememberto name one of the probes LTCDIFF, LTCDIF1 or LTCDIF2. Evaluation of theLTC set point is not done unless one of the probes is named LTCDIFF.

Figure 4.3 illustrates how the LTC differential set point operates for LTC conditionmonitoring.

V1.00, August 30, 200441

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 drop 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 youmonitor 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 load transformer. The LTCPUTMR can beset 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 isreached. 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.

42 V1.00, August 30, 2004

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.

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 it’s 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.

PRGM SETTING 042LTCPUTMR1=480MIN

V1.00, August 30, 200444

Figure 4.4: 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”.

NOTE: The calculated winding temperature feature will not functioncorrectly when monitoring the cooling system’s load current.

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 nodebounce 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 4.7 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 4.7: 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

V1.00, August 30, 200449

Assigning SP11 ! to OUT3 and SP21 ! and SP12 + to OUT3 will result in thefollowing Boolean expression:

OUT3 = SP12 ! SP11!SP21

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) ! SP11!SP21

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 useof 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.

4.9.5 Assigning IN1 and IN2

The IN1 and IN2 can be incorporated into the programmable logic by assigningthese points to a specific output. IN1 and IN2 are useful if you wish to start astage of cooling through a switch on the control panel or even from your RTU. Itcan also be used to block an output relay should the need arise.

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 at04:00 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

4.9.8 Setting Output Timers

Setting the output timers delays the pickup of the output by the number ofseconds set. Each output has its own timer capable of being set from 0 to 255seconds. A setting of 0 will permit the output to pickup as soon as all of theprogrammable logic criteria are met. The output timer is only used in conjunctionwith the programmable logic and has no effect in manual, remote or alarmcontrol.

Programming the time set point counter from the front panel, press the %%%% or&&&&arrow buttons until the setting 052 is displayed:


For programming from a PC just type the output timer value on the “Enter:” lineas follows:

Enter:47/15)

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 setting085 is displayed:

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:88/1)

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 thecontroller 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.

V1.00, August 30, 200462


The following are some applications 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


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

V1.00, August 30, 200463

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 asfollows:

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

V1.00, August 30, 200464

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 isa 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.

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)






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.

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.

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 eithercurrent loop outputs and a RS-485 DNP3.0 communications interface. All TTC-1000’s come equipped with a 9 pin DB-9 connector for RS-232 ASCIIcommunications. Temperature information can be retrieved through the RS-232interface.

5.1 Analog Outputs

The 3 Probe Version of the TTC-1000 is currently unavailable with analogoutputs. This option will be a plug-in that will be available shortly.

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 or full duplex isolated RS-485 asynchronous communications interface capable of supporting multi-droptopologies. RS-485 interfaces differ from RS-232 in that RS-485 uses adifferential receiver and transmitter pair. This permits RS-485 links to send andreceive data over much greater distances as long as some simple rules arefollowed. See Section 3.7.3 for connections and jumper 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 load

V1.00, August 30, 200475

data 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 localautomatic 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. User’s 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, remotecommanding 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 of

implementation 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 13 for additional detailsand specific definitions of all points supported.

5.3 Telemetry Via RS232

Asynchronous data communications is implemented through the front panelmounted DB-9 connector at a fixed data rate of 9600 bits per second, 8 bits ofdata, 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, theexact format of the reply for a single probe unit is:

/T68

For dual probe versions, the display will read:

/T68/93

Where the first temperature is probe #1 and the second is probe #2.

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.

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, P3’stemperature, calculated winding temperature, and load. Once the log is full, theoldest records are over written with the newest records. Since the records arestored in non-volatile memory, records are never lost even in the event of apower 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 includeprobe 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.

V1.00, August 30, 2004106

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 anon-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, P2, or P3 the data recordedtakes the name chosen for the specific temperature probe. If P1, P2 or P3 ischosen as LTCDIFF, the data recorded is the differential between the LTC tanktemperature and the Top Oil probe. All other temperature points are recorded asthe absolute value 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 099 is displayed:


For programming from a PC, enter PROGRAM through the main menu asdiscussed in Section 4.2. Once in PROGRAM, type the setting for the time baseon the “Enter:” line as follows:

V1.00, August 30, 2004107

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 thelog: P1, P2, Calculated Winding, and Load. The heading names for probes P1and P2.in the data log will be as displayed on the front panel.
