InteliATSNT is a comprehensive Automatic Transfer Switch controller designed to mon AC mains supply (1 or 3 phases) for under & over voltage, under & over frequency anunbalance. In the case of any mains supply disproportion it will send a remote start cogen-set and make changeover for both

The controller is capable of providing the following three dif • open delayed transition• open in-pase transition with synch check• closed short-time (100ms) parallel transition with synch check

In order to provide “synch check” the controller has been enhanced by the feature called pasynchronization. The passive sync (sync check) offers possibility to “synchroniwithout the need to use speed regulation or - better to say - it offers possibility to wasources to get in phase.System is evaluated as to be in sync according to the predefined parameters – vdifference – if the both sources will get in-phase before the synchronization timeoutParameters defining breaker delay are taken into the account when the system compexact moment when the both sources are “in phase”.

Configurability

One of the key features of the controller is high level of adaptability of the system to the needs ofy particular application. The way, how to achieve this, is the configuration.ever

NOTE: Use LiteEdit PC software to read configuration from the controller or disk, view it, modify it and writethe configuration to controller or disk.

The firmware contains a number of binary inputs and outputs needed for all necessaryavailable in the

functionsfirmware. But not all functions are required at the same time on different gen-sets and

also the controller hardware does not have so many input and output terminals. One of the main tasksion is mapping of "logical" firmware inputs and outputs to the "physical" hardware

NOTE: The InteliATSNT controller should be grounded properly in order to protect against lighting strikes!!The maximum allowable current through the controller’s negative terminal is 4A (this is dependent onbinary output load).

For the connection NTs with 12VDC power supply, the InteliATS includes internal capacitors that allowthe controller to continue operation if the battery voltage dip occurs. If the voltage before dip is 10V,after 100ms the voltage recovers to 7 V, the controller continues operating. During this voltage dip thecontroller screen backlight can turn off and on but the controller keeps operating.It is possible to further support the controller by connecting the external capacitor and separatingdiode or I-LBA module:

The capacitor size depends on required time. It shall be approximately thousands of microFarads.The capacitor size should be 5 000 microFarad to withstand 150ms voltage dip under followingconditions:Voltage before dip is 12V, after 150ms the voltage recovers to min. allowed voltage, i.e. 8V

Three phase application:

It is necessary to ensure that potencial difference between generator current COM terminal andbattery “ -” terminal is maximally ± 2V. Therefore is s trongly recommended to interconnect

these two terminals together.

It is possible to set the location of CT s.

There are two options of CT location.• Load• Gen-Set

According to the connection you have to set the setpoint CT location value to Load or Gen-Set

Voltage measurement and generator connection types

There are 4 voltage measurement ConnectionTypes (setpoint ConnectionType [3Ph4Wire /

3Ph3Wire / Split Ph / Mono Ph] ) options. Every type matches to corresponding generator connectiontype:

1. ConnectionType: 3 Phase 4 Wires




Three phase “wye” measurement – 3PY

2. ConnectionType: 3 Phase 3 Wires

Three phase “ delta” measurement – 3PD

3 Phase 3 Wires

– DELTA Connection – HI-LEG (wild-leg, red-leg) DELTA Connection




NOTE: Only L1, L2 and L3 wires should be connected. In case of HI-LEG DELTA connection the N (neutral)wire (in the diagram connected between T6 and T9) has to be disconnected.No separation transformers for three wires voltage connection (without N) are needed.

3. ConnectionType: Split Phase

4. ConnectionType: Mono Phase

Mono Phase – MONOPHASE Connection

NOTE: Switchboard lighting strike protection according standard regulation is expected for all 4 connectiontypes!!!

NOTE: Phase sequence check is not possible to evaluate under voltage 50V what causes that if measuredvoltage 50V is within the allowed range, controller will not allow to close the GCB, even if relevant LEDdiod on front panel of IL-NT lits.

Bellow you can see how is Open Delay Transition implemented by I

HINT:This transition can perform fastest possible changeover if Transfer Del is set to zero value.Overall blackout time then equals to 20 ms + breaker reaction time.

HINT: Use longer delay time to avoid problems with motor starters. (Motor starts prefer to see break of afew seconds so they can initialize properly).

HINT: To avoid issues with contactor mechanical interlocks use delay 0.75s or longer (mech. interlock oncontactors takes some time to clear). If you try to close one contactor before interlock has clearedit can jam and you end up with out supply to load).

Picture above shows how is Open In-phase Transition implemented by IA-NT controllers.

In case of system using two separate breakers/contactors controller ensures no overlap betweenboth switches during changeover however mechanical interlock can still be useful.Two or three position ATS switches ensure this by its nature.

HINT:




It is necessary to use fast breakers with known closing/opening time when Open In-phaseTransition takes place. Breaker switching time is used as parameter (MCB Delay, GCB Delay) forcalculation/prediction of exact in-sync moment.Overall blackout time equals to 100 ms + one breaker reaction time (incl. control relay delay).

HINT:

In case of source (e.g. mains) failure changeover from source is always performed as opendelayed, not as in-phase.

HINT:During system tests two separate breakers/contactors with switching time below 50ms were usedalong with fast ATS switches (e.g. SOCOMEC ATyS M 3s, switching time 180 ms). We do not recommend usage of switching elements their reaction time exceeds these values!

HINT:Breaker delay default value for both breakers (MCB Delay, GCB Delay) is set to 50ms. ATS switchdelay consists of both delays.

3. Closed Transition

Closed Transition presents transition type where both breakers/contactors overlap for 100 ms andis suitable for

on time of wholeswitching mechanism (including control relays) affects overall changeover time.

It is required to use as fast switches as possible (breaker opening time < 100 ms including controlrelay). If parallel run exceeds 200 ms both breakers are opened and alarm is activated. If parallelrun still continues (breakers are closed for at least 100 additional milliseconds), binary output

Shunt Trip is activated (if configured).

transition initiates only when both power sources are in sync. This kind of transitionsuch systems where no break (no blackout) changeover is required. Transfer Del setpoint valuis ignored (equals to zero).

See description of passive synchronization for more info.

Two independent breakers/contactors are required as switching elements. Reacti




HINT:It is necessary to use fast breakers with known closing/opening time when Closed Transition takesplace. Breaker switching time is used as parameter (MCB Delay / GCB Delay) forcalculation/prediction of exact in-sync moment.

Direct connection to the PC

InteliATSNT can be connected directly with PC via optional IL-NT RS232 interface.NTUse the standard serial cable to connect PC with InteliATS .

NOTE: Make sure the grounding system on controller and PC – COM port (negative of the PC DC supply) areidentical – before the first direct connection. There must not be any voltage between these two pointsotherwise the internal reversible fuse in controller burns out. The simple solution is to assure, that thePC supply 240/20V is ground free (GND terminal is not connected).

Communication object vs. Register All the data intended for communication has its representation as communication objecontroller. The communication object is represented by the n-byte array in the controllidentified by the unique 16-bit communication object number. The register, according tcommunication protocol, represents a two-byte data and in communication functions i16-bit register address. Further in the description of communication functions the com
