General Guidelines
What is in this manual?
This manual describes the InteliATSNT PWR (IA-NT-PWR) software, which is designed for automatic
transfer switch applications and provides general information on how to install and operate the
InteliATSNT controller.
This manual is dedicated for
Automatic transfer switch panel builders
Operators of remote gen-sets (started remotely from InteliATSNT)
For everybody who is concerned with installation, operation and maintenance of the gen-set
InteliATS controller SW and HW versions compatibility
Software InteliATSNT is compatible with the InteliATSNT hardware v. 1.3 and higher.
There are two modifications of the InteliATSNT HW - STD and PWR and two modifications of the
InteliATSNT SW – STD and HW which together with the appropriate archive file (IA-NT-STD-HW_1.3X.X.AIL for STD HW 1.3, IA-NT-STD-X.X.AIL for STD HW > 1.3 and IA-NT-PWR-X.X.AIL) form the
InteliATSNT PWR or STD controller.
Beside that the InteliATSNT software is compatible with IL-NT AMF HW 1.3 and higher too, which is
used when a low temperature ATS application is needed. In this case the InteliATSNT SW must be
combined (purchased) with the IL-NT AMF 25 LT HW to obtain the low temperature ATS controller.
NOTE:
Because of large variety of InteliATSNT parameters settings, it is not possible to describe all
combinations. Some of InteliATSNT functions are subject of changes depend on SW version.
The data in this manual only describes the product and are not warranty of performance or
characteristic.
CAUTION!
SW and HW must be compatible (e.g. IA-NT firmware and IA-NT HW) otherwise the function will be
disabled. If wrong software is downloaded, message HARDWARE INCOMPATIBLE appears on
controller screen. In this case use Boot load (jumper) programming – close Boot jumper and follow
instructions in LiteEdit, download correct software.
NOTE:
ComAp believes that all information provided herein is correct and reliable and reserves the right to
update at any time. ComAp does not assume any responsibility for its use unless otherwise expressly
undertaken.

Description
Description of the controller system
InteliATSNT is a comprehensive Automatic Transfer Switch controller designed to monitor the incoming
AC mains supply (1 or 3 phases) for under & over voltage, under & over frequency and voltage
unbalance. In the case of any mains supply disproportion it will send a remote start command to the
gen-set and make changeover for both generator and mains contactors. The gen-set requires a
remote start type control unit (e.g. the ComAp InteliLiteNT MRS 10 controller), at least a key-start box
with an external input for the start/stop signal.
The controller is capable of providing the following three different types of changeover (transition)
open delayed transition
open in-phase 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 passive
synchronization. The passive sync (sync check) offers possibility to “synchronize” mains and gen-set
without the need to use speed regulation or - better to say - it offers possibility to wait for the both
sources to get in phase.
System is evaluated as to be in sync according to the predefined parameters – voltage and frequency
difference – if the both sources will get in-phase before the synchronization timeout expires.
Parameters defining breaker delay are taken into the account when the system computes/predicts
exact moment when the both sources are “in phase”.
InteliATSNT controllers are equipped with a powerful graphic display showing icons, symbols and bargraphs for intuitive operation, which sets, together with high functionality, new standards in Gen-set
controls & ATS Breaker.
The key features are:
Easy-to-use operation and installation. Factory default configuration covers most of
applications
Different customer changes are possible thanks to the configurability
Excellent remote communication capabilities
High reliability

IA-NT- PWR-2.5-Reference Guide.pdf
Configurability
One of the key features of the controller is high level of adaptability of the system to the needs of
every particular application. The way, how to achieve this, is the configuration.
NOTE:
Use LiteEdit PC software to read configuration from the controller or disk, view it, modify it and write
the configuration to controller or disk.
The firmware contains a number of binary inputs and outputs needed for all necessary functions
available in the firmware. 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 tasks
of the configuration is mapping of "logical" firmware inputs and outputs to the "physical" hardware
inputs and outputs.
Configuration parts:
1. Mapping of logical binary inputs (functions) or assigning alarms to physical binary input
terminals
2. Mapping of logical binary outputs (functions) to physical binary output terminals
3. Changing language of the controller texts
The controller is delivered with a default configuration, which should fit to most standard
applications. This default configuration can be changed only using PC and LiteEdit software. See
LiteEdit documentation for details.
NOTE:
You need one of communication modules to connect the controller to a PC with LiteEdit. There is a
special easy removable service module for cases, where there is no communication module
permanently attached.
Once the configuration is modified, it can be stored in a file for later usage with another controller or
for backup purposes. The file is called archive and has file extension ".ail". An archive contains full
image of the controller at the moment of saving (if the controller is online to the PC) except firmware,
i.e. besides configuration there are also current adjustment of all setpoints, all measured values, a
copy of history log and a copy of alarm list.
The archive can be simply used for cloning of controllers, which means preparing controllers with
identical configuration and settings.

IL-NT-GPRS GSM and GPRS plug-in modem
CAUTION!
Any manipulation with plug-in module shall be done with disconnected power supply to both controller
and module. Power supply shall be switched on also is same time to both module and controller. Fail
to follow these instructions (power supply active only in controller or only in module) can lead to
module or controller failure!
This plug-in module is a GSM/GPRS modem which can work in two modes of operation based on the
settings in the setpoint COM1 Mode.
Settings DIRECT = the module works in a GPRS network and enables connection via AirGate
to LiteEdit and WebSupervisor as well as sending SMS alarms.
Settings MODEM = the module works as a standard GSM modem enabling a CSD (Circuit
Switch Data) connection to the controller with LiteEdit or InteliMonitor and sending SMS
alarms.
The communication module IL-NT GPRS works with:
WebSupervisor – internet-based remote monitoring solution
AirGate – powerful connection technology to make internet access as simple as possible
Locate – localization technology
HINT:
Quick guide how to start using this module is in chapter Remote Communication - Short guide how to
start using IL-NT-GPRS module or on ComAp webpage http://www.comap.cz/products/detail/IL-NTGPRS.
GPRS and CSD services must be provided by your GSM/GPRS operator for successful operation.
The GPRS and CSD connection should not be used for the firmware update process. Use instead a
wired connection like RS232, USB, RS485 or Ethernet via IB-Lite!
IL-NT-GPRS module doesn’t support a sending of e-mails.
It is necessary to power the controller and individually the IL-NT GPRS module as well.

User Interface
There is an interchangeable User Interface on controller. It allows two different modes of displaying
controller menu.
The first mode called USER is dedicated for users who prefer easy function and need only monitor
actual values, see alarms or change language settings.
Second mode is called ENGINEER and it is dedicated for advanced users, who desire to change the
settings of controller, monitor all values and check the history of events.
Changing the mode of User Interface is possible from default measuring screen of controller by
simultaneous pressing the ENTER and PAGE button and then press again PAGE. On screen will be
displayed the choice of two different User Interfaces.

Applications
The most typical application for the ATS controllers is Auto Mains Failure (AMF) application, where the
controller watches for the mains power supply fault and then starts a load transfer process.
Next possible application is manually controlled load transfer between two power supply sources
(mains x generator).

Specification
It is possible to operate controller without a battery supplying the controller. For such operation the
following conditions have to be fulfilled:
Controller is supplied from 24V/2.5A AC/DC power supply whose source is switched between
Mains and Gen-set via relay (another contacts of the relay for GCB switching) according to
the Mains state (OK/Fault). See the schematic diagram for more details
Normally closed relay contacts have to be used for the gen-set start command. Setpoint
“GenStart Logic” has to be set to CLOSE-OFF
Switching of the 24V AC/DC power supply is blocked when GCB is closed, so the power
supply is not switched to Mains if voltage on the mains bus appears – protection against
“Flip-flopping” of the power supply when voltage changes arise on Mains.
It (power supply) will be switched to Mains when GCB is opened.
Then in the case of Mains failure:
24V AC/DC power supply source is switched to gen-set
Voltage supplying controller disappears
Gen Start relay is deenergized and contacts closed
Gen-set is started
Controller is supplied from running gen-set
Controller is initialized, waits for Gen OK conditions
MCB is opened, GCB closed and the 24V AC/DC power supply source is locked in gen-set
position.
If Mains returns:
GCB is opened, 24V AC/DC power supply source is unlocked and switched to Mains
MCB is closed
Gen-set is stopped

Getting Started
How to install
General
To ensure proper function:
Wiring for binary inputs and analog inputs must not be run with power cables.
Binary inputs should use shielded cables, especially when length >3m.
CAUTION!
This device is dedicated for enviroment conditions type A. Usage of this device in enviroment
conditions type B can cause electromagnetic disturbance. In this case it can be demand to make
adequate steps to reduce this electromagnetic disturbance.
Power supply
To ensure proper function use min. power supply cable of 1.5mm2
Maximum continuous DC power supply voltage is 36VDC. The InteliATS
NT
’s power supply terminals
are protected against large pulse power disturbances. When there is a potential risk of the controller
being subjected to conditions outside its capabilities, an outside protection devise should be used.
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 on
binary output load).
For the connections with 12VDC power supply, the InteliATSNT includes internal capacitors that allow
the controller to continue operation if the battery voltages 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 the
controller 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 separating
diode 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 following
conditions:
Voltage before dip is 12V, after 150ms the voltage recovers to min. allowed voltage, i.e. 8V
NOTE:
Before the battery is discharged the message "Low BackupBatt" appears.
Or by connecting special I-LBA Low Battery Adaptor module:
Page 36
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 36
IA-NT- PWR-2.5-Reference Guide.pdf
The I-LBA module ensures min. 350ms voltage dip under following conditions:
RS232 and other plug-in module are connected.
Voltage before dip is 12V and after 350ms the voltage recovers to min. allowed voltage 5V.
The I-LBA enables controller operation from 5VDC (for 10 to 30 sec).
The wiring resistance from battery should be up to 0.1 Ohm for I-LBA proper function.
NOTE:
I-LBA may not eliminate voltage drop when used with low temperature (-40°C) version of controller
and display heating element is on (below 5°C). Current drain of heating element exhausts LBA
capacitors very fast
Power supply fusing
A one-amp fuse should be connected in-line with the battery positive terminal to the controller and
modules.
Fuse value and type depends on number of connected devices and wire length.
Recommended fuse (not fast) type - T1A. Not fast due to internal capacitors charging during
power up.
Binary output protections
NOTE:
Do not connect binary outputs directly to DC relays without protection diodes, even if they are not
connected directly to controller outputs.
Grounding
To ensure proper function:
Use as short as possible cable to the grounding point on the switchboard
Use cable min. 2,5mm2
The “-“ terminal of the battery has to be properly grounded
Page 37
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 37
IA-NT- PWR-2.5-Reference Guide.pdf
Current measurement
The number of CT’s is automatically selected based on selected value of setpoint ConnectionType
[3Ph4Wire / 3Ph3Wire / Split Ph / Mono Ph].
HINT:
Further information about measurement limits are at setpoint CT Ratio [/5A] description in chapter
Setpoints - Basic Settings.
Generator currents and power measurement is suppressed if current level is bellow <1% of CT
range.
To ensure proper function:
Use cables of 2,5mm
2
Use transformers to 5A
Connect CT according to following drawings:
Three phase application:
It is necessary to ensure that potential difference between generator current COM terminal and
battery “-” terminal is maximally ± 2V. Therefore is strongly recommended to interconnect
these two terminals together.
Single phase application:
Connect CT according to following drawings. Terminals L2l and L3l are opened.
Page 38
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 38
IA-NT- PWR-2.5-Reference Guide.pdf
CT location
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. Use 1A fuse on voltage measurement inputs. Every type
matches to corresponding generator connection type:
1. ConnectionType: 3 Phase 4 Wires
Three phase “wye” measurement – 3PY

Transition [OPEN/INPHASE/CLOSED/INPH-OPEN/CLOS-OPEN]
Ability to perform passive synchronization dramatically enhances controller function and brings
possibility to provide Open In-phase Transition and Closed Transition (short time parallel). Controller
provides below described types of changeover between Mains and Gen-set power sources depending
on following setpoint value:
OPEN Open Delayed Transition
IN-PHASE Open In-phase Transition
CLOSED Closed Transition
INPH-OPEN Open In-phase Transition or Open Delayed Transition
CLOS-OPEN Closed Transition or Open Delayed Transition
1. Open Delayed Transition
Open Delayed Transition is standard type of changeover provided by most common AMF or ATS
controllers supplied by other vendors. Controllers perform load transfer between both power
sources with break (blackout). Delayed Transition means there is delay between source breaker
opening and target breaker closing.
Two or three position ATS switch or two independent breakers/contactors can be used as
switching mechanism.
Bellow you can see how is Open Delay Transition implemented by IA-NT controllers. Our
controllers offer possibility to setup load transfer delay via Transfer Del setpoint.
Page 58
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 58
IA-NT- PWR-2.5-Reference Guide.pdf
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 a
few seconds so they can initialize properly).
HINT:
To avoid issues with contactor mechanical interlocks use delay 0.75s or longer (mech. interlock on
contactors takes some time to clear). If you try to close one contactor before interlock has cleared
it can jam and you end up without supply to load).
2. Open In-phase Transition
Open In-phase Transition represents special kind of Open Delayed Transition where delay during
changeover is reduced to minimal possible value and transition initiates only when both power
sources are in sync. Transfer Del setpoint value is ignored (equals to zero). See description of
passive synchronization for more info.
This kind of transition is suitable for such systems where fast changeover (very short blackout) is
required, huge inductive load (e.g. large electric motor) is involved and it is not possible to use
Closed Transition due to some reason.
Two or three position ATS switch or two independent breakers/contactors can be used as
switching element. Reaction time of whole switching mechanism (including control relays) affects
overall changeover time and in-phase transfer accuracy.
Page 59
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 59
IA-NT- PWR-2.5-Reference Guide.pdf
It is recommended to use as fast switches as possible (overall switching time <<
200 ms). The faster the better to ensure real in-phase transition –> once sync
moment is calculated and source is disconnected from load, electrical parameters
of load are changing dynamically and could fall out of sync rapidly. Real phase
difference depends on that switching time.
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 between
both 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-phase
Transition takes place. Breaker switching time is used as parameter (MCB Delay, GCB Delay) for
calculation/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 open
delayed, not as in-phase.
HINT:
During system tests two separate breakers/contactors with switching time below 50ms were used
along 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!
Page 60
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 60
IA-NT- PWR-2.5-Reference Guide.pdf
HINT:
Breaker delay default value for both breakers (MCB Delay, GCB Delay) is set to 50ms. ATS switch
delay consists of both delays.
3. Closed Transition
Closed Transition presents transition type where both breakers/contactors overlap for 100 ms and
transition initiates only when both power sources are in sync. This kind of transition is suitable for
such systems where no break (no blackout) changeover is required. Transfer Del setpoint value
is ignored (equals to zero).
See description of passive synchronization for more info.
Two independent breakers/contactors are required as switching elements. Reaction time of whole
switching mechanism (including control relays) affects overall changeover time.
It is required to use as fast switches as possible (breaker opening time < 100 ms
including control relay). If parallel run exceeds 200 ms both breakers are opened
and alarm is activated. If parallel run still continues (breakers are closed for at
least 100 additional milliseconds), binary output Shunt Trip is activated (if
configured).
HINT:
It is necessary to use fast breakers with known closing/opening time when Closed Transition takes
place. Breaker switching time is used as parameter (MCB Delay / GCB Delay) for
calculation/prediction of exact in-sync moment.
HINT:
In case of source (e.g. mains) failure changeover from source is always performed as open
delayed, not as closed.
HINT:
Page 61
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 61
IA-NT- PWR-2.5-Reference Guide.pdf
During system tests two separate breakers/contactors with switching time below 50ms were used.
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.
4. In-phase + Open Delayed Transition, Closed + Open Delayed Transition
If Setpoint Transition equals to [INPH-OPEN] or [CLOS-OPEN], system continues with Open
Delayed Transition after requested synchronized transition failed (sync timeout expired sooner
than both sources reached synchronized state)

generator voltages disappeared). If the engine is still running after the stop time expires the Wrn Stop
Fail alarm is announced. Stop Fail starts counting always when the controller sends Stop command to
the engine (Start/Stop output is deactivated).
Step: 1 s
Range: 0 – 3601 sec Value 3601 means the controller doesn’t care for the engine is
stopped (Wrn Stop Fail is never announced).
Power switch function
This switch is assigned to the gen-set active power. Typical usage for this binary output can be
switching of dummy load. The output behaves based on the setpoint adjustment as described on
picture below:

Programmable delay on alarms
Possibility to set programmable delay on alarms configured for binary input 6 and 7 has been added. If
set, it blocks alarms of the respective binary input for the whole time the delay is active. If the reason
for the alarm persists after the delay time expired, the alarm is activated. If not, the alarm does not
appear. This feature allows the user to perform “filtering” of alarms within a specified period of time.
The delay length can be set via the following setpoints:
BI6 Delay [s]
Delay for alarm on binary input nr. 6
Step: 0.1 s
Range: 0 – 360.0 s

HINT:
Over- and undervoltage protection is evaluated according to Basic Settings: ConnectionType setting.
3Ph4Wire and 3Ph3Wire connections are evaluated according to Ph-Ph nominal voltage (NomVolts
Ph-Ph) and Split Phase and Mono Phase connections are evaluated according to Ph-N nominal
voltage (NomVolts Ph-N).
HINT:
To evaluate Mains > V and Mains < V the controller has implemented additional hysteresis.
If “Mains <V” <= 90% then hysteresis for “Mains <V” = ±4%
If “Mains >V” >= 110% then hysteresis for “Mains >V” = ±4%
If “Mains <V” >90% then hysteresis for Mains <V is calculated as 40% from (100 – “Mains <V”)
If “Mains >V” <110% then hysteresis for “Mains >V” is calculated as 40% from (100 – “Mains >V”)

SMS/E-Mail
Remote alarm messaging
If a GSM modem and/or InternetBridge-NT is connected to the controller, the controller can send SMS
messages and/or emails in the moment when a new alarm appears in the Alarm list. The message will
contain a copy of the Alarm list.
To enable this function, you should select with setpoints Yel Alarm Msg and Red Alarm Msg, which
levels of alarms shall be announced (red/yellow/both) and also enter valid GSM phone number and/or
e-mail address to the setpoints TelNo/Addr Ch1 and TelNo/Addr Ch2. It is possible to put either a
GSM number or e-mail to both setpoints.
The list of all supported terminals shows the table below:

Controller is capable to detect which communication terminal is connected to the network and send
the email/SMS via the active one. InternetBridge-NT is preferred terminal if more possibilities are
detected.
NOTE:
An internet module must be available for sending of e-mails. Similarly, a GSM modem is necessary for
sending of SMS.
NOTE:
There are 5 attempts for any active call (SMS/E-Mail). Timeout for connection is 90 sec and after 120
sec controller starts the next attempt. During the time the IA-NT is trying to send an active call type,
incoming calls are blocked.
Yel Alarm Msg [DISABLED, ENABLED]
Set this setpoint to YES if you want to get messages when a yellow (warning) alarm occurs.
NOTE:
The target address (GSM phone number or e-mail address) must be set correctly to the setpoint(s)
TelNo/Addr Ch1 resp. TelNo/Addr Ch2.
Red Alarm Msg [DISABLED, ENABLED]
Set this setpoint to YES if you want to get messages when a red (Trip) alarm occurs.
NOTE:
The target address (GSM phone number or e-mail address) must be set correctly to the setpoint(s)
TelNo/Addr Ch1 resp. TelNo/Addr Ch2.
TelNo/Addr Ch1, 2
Enter either a valid GSM phone number or e-mail address to this setpoint, where the alarm messages
shall be sent. Type of active call is considered from the value of this parameter. If it consist „@“ it is
Page 76
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 76
IA-NT- PWR-2.5-Reference Guide.pdf
supposed to be e-mail address and active e-mail is sent. If the value is number, without „@“, it is
supposed to be the telephone number and active SMS is sent.
NOTE:
For GSM numbers use either national format (i.e. like number you will dial if you want to make a local
call) or full international format with "+" character followed by international prefix in the beginning.
This setpoint can be modified from PC only!
SMS Language [1/2]
Select 1 to receive a message in primary controller language or 2 for secondary one.

Function Description
Operating modes
Selection of the operating mode is done through Mode buttons on the front panel or by changing of the
Controller mode setpoint (from the front panel or remotely).
NOTE:
If this setpoint is configured as password-protected, correct password must be entered prior
attempting to change the mode.
NOTE:
Mode can not be changed, if Access Lock input is active.
There are following binary inputs that can be used to force one respective operating mode
independently on the mode setpoint selection:
Remote OFF
Remote MAN
Remote AUT
Remote TEST
Rem TEST OnLd
If the respective input is active the controller will change mode to the respective position according to
the active input. If more inputs are active the mode will be changed according to priorities of the
inputs. The priorities match the order in the list above. If all inputs are deactivated the mode will return
to the original position given by the setpoint.
OFF
The behavior of the controller in OFF mode depends mainly on setting of the ActivityAtOff setpoint.
No activity
Setpoint ActivityAtOff = DISABLED.
The controller opens all binary outputs and Fault reset is active all the time. Output controlling MCB
remains unchanged!
Standard activity
Setpoint ActivityAtOff = ENABLED.
The GCB will be opened and the engine will be immediately stopped without unloading and cooling.
The MCB is closed permanently (MCB Opens On = GENRUN) or is closed or open according to the
mains is present or not (MCB Opens On = MAINSFAIL). No AMF (Auto Mains Failure - evaluates
Mains failure / return) function will be performed. Buttons MCB, GCB, START, STOP including the
appropriate binary inputs for external buttons are not active. Output GenStart/Stop is not energized.
MAN
The engine can be started and stopped manually using START and STOP buttons (or external buttons
wired to appropriate binary inputs) in MAN mode. This will activate/deactivate GenStart/Stop binary
output which polarity depends on GenStart Logic setpoint. When the engine is running, GCB can be
closed to a dead bus. Also MCB can be closed and opened manually using the MCB button,
regardless the mains is present or not. No autostart is performed. No reaction to the input Rem
Start/Stop.
NOTE:
The engine can run without load unlimited time. The controller does not automatically stop the running
gen-set in MAN Mode and does not start the gen-set when power cut comes.
Page 78
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 78
IA-NT- PWR-2.5-Reference Guide.pdf
NOTE:
The breakers are internally locked to close two voltages against each. The controller will automatically
recognize if the breaker can be closed, it means it is never possible to close both breakers together
NOTE:
If some voltage arises on generator bus (e.g. gen-set was started externally - not via IA-NT), generator
LED blinks and [Stop], [MCB], [GCB] buttons are inactive. To bring them into operation [Start] button
has to be pressed - it will synchronize IA-NT with gen-set state.
CAUTION!
The MCB can be opened manually in MAN mode. Accidental opening the MCB will cause the object
(load) will remain without power!!!
AUT
The engine is started and stopped either by the binary input Rem Start/Stop or by the AMF
mechanism or by the manual transfer request via Rem Transfer binary input. Buttons MCB, GCB,
START, STOP including the appropriate binary inputs for external buttons are not active. The full start
sequence up to the moment when the engine is loaded is automatic as well as unloading and stop
sequence.
The controller behavior when gen-set is stopped and restarted again whilst the mains failure
constantly persists:
If the problem on the gen-set side appears, all faults messages are auto-quit and no next
operation is blocked
Gen-set Start/Stop signal stays active
Controller waits for gen-set parameters are OK (means GenReadyToLoad signal is activated or
generator voltages are in allowed limits) and then GCB is reclosed
For ensuring GCB Open/Close output remains off whilst Gen Voltage is OK long enough to
rewind the Circuit breaker to the off position use the Transfer Del setpoint

If during start-up sequence mains returns, then MCB is reclosed with delay MCB Close Del (if
opened, depending on MCB Opens On setpoint) and start-up sequence is interrupted.
3
If mains fails during stop procedure (cooling) again, stop sequence is interrupted, MCB opened and
GCB reclosed with delay Transfer Del.
See also chapters: Circuit breakers timing and AMF time chart.
WARNING!
If an red alarm is present and the gen-set is in AUT mode, it can start by self after all red alarms
becomes inactive and are acknowledged!!!
TEST
The behavior of the controller in TEST mode depends mainly on setting of the ReturnFromTEST
setpoint.
Automatic return
Setpoint ReturnFromTEST = AUTO.
The gen-set will be started when the controller is put to TEST mode and will remain running unloaded.
If a mains failure occurs, the MCB will be opened and after Transfer Del the GCB will be closed and
the gen-set will supply the load. After mains is recovered, the delay MainsReturnDel will count
down and if elapses and the mains is still ok, the controller will transfer the load back to the
mains and the gen-set will remain running unloaded again until the mode is changed.
Manual return
Setpoint ReturnFromTEST = MANUAL.
The gen-set will be started when the controller is put to TEST mode and will remain running unloaded.
If a mains failure occurs, the gen-set will take the load.
The load can be transferred to the gen-set also manually:
If the MCB button is pressed, the controller will open the MCB, then wait for Transfer Del and
finally close the GCB.
Once the load is supplied by the gen-set, the gen-set remains supplying it until the controller is
switched to other mode.
Test with load
If the binary input Rem TEST OnLd is activated, the controller is switched to TEST mode (i.e. the genset will be started as described above), but once started the controller will automatically make a
switchover, i.e. open MCB, wait for Transfer Del and close GCB.
After the binary input Rem TEST OnLd has been deactivated, the controller goes back to previous
operation mode and it's behavior depends on it. In most cases it will be AUT mode and the controller
will either stay supplying the load if the mains is failed, or will transfer the load back to the mains.
Periodic exercises
The output from the Exerc timer 1 is internally connected to the Remote TEST binary input to enable
periodic testing of the gen-set.
The controller must have AUT mode selected by mode buttons and other "mode forcing" binary inputs
must not be active to ensure proper function of the exercise.
NOTE:
If a Trip or other red alarm comes while the load is supplied from the gen-set and the mains is healthy,
the load is switched back to the mains.
CAUTION!
The gen-set starts automatically and is always running in TEST mode!

Source evaluation
Source evaluation is same for generator and mains. Setpoints and binary inputs connected with
source evaluation are:
GenProtect setpoint (for generator)
MainsProtect setpoint (for generator)
GenReadyToLoad binary input (for mains)
MainsHealthy binary input (for mains)
State of source can be evaluated in these ways:
Binary input only
Measured values only
Binary input and measured values
Binary input only
In this case the binary input GenReadyToLoad or MainsHealthy has to be configured. After
configuration of binary input, related setpoint GenProtect or MainsProtect should be adjust to
DISABLED. After that the source will be evaluated only from binary inputs.
Measured values only
In this case the binary input GenReadyToLoad or MainsHealthy can´t be configured. Related setpoint
GenProtect or MainsProtect is adjust to valeu ENABLED and its value can´t be changed. Source is
evaluated only from measured values (voltage and frequency).
Binary input and measured values
In this case the binary input GenReadyToLoad or MainsHealthy has to be configured After
configuration of binary input, related setpoint GenProtect or MainsProtect should be adjust to
ENABLED. After that the source will be evaluated from both sources. To evaluate that source is health
the values of voltage and frequency have to be in limits and also related binary input has to be in
logical one.

Voltage phase sequence detection
InteliATSNT controller detects phase sequence on both generator and mains/bus voltage terminals.
These protections are important after controller installation to avoid wrong voltage phases connection.
Following alarms can be detected:
Wrong phase sequence
There is fix defined phase sequence in InteliATSNT controller L1, L2, L3. When the phases are
connected in different order (e.g. L1, L3, L2 or L2, L1, L3) following alarms are detected:
Gen CCW Rot = wrong generator phase sequence
Mains CCW Rot = wrong mains phase sequence
GCB, MCB fail detection
MCB or GCB fail detection is based on binary output CB close/open comparing with binary input CB
feedback.
There are three different time delays for CB fail detection – see following diagrams.
When is BO GCB close/open (MCB Close/Open) in steady state and GCB feedback (MCB feedback)
is changed the GCB fail is detected immediately (no delay).

Direct cable connection
An external communication module is necessary to enable direct cable connection to a PC. The
module is plugged into the slot located on the rear side of the controller. Find more information about
installation of the modules in a separate chapter.
A RS232, USB or RS485 interface can be used for direct cable connection to a PC. The setpoint
COM1 Mode or COM2 Mode (according to the interface used) must be set to DIRECT position for this
kind of connection.

NOTE:
Use a cross-wired serial communication cable with DB9 female connectors and signals Rx, Tx, GND
for a RS232 connection.
HINT:
Make sure the grounding system on controller and PC – COM port (negative of the PC DC supply) are
identical – before the first direct connection. There must not be any voltage between these two points
otherwise the internal reversible fuse in controller burns out. The simple solution is to assure, that the
PC supply 240/20V is ground free (GND terminal is not connected).

The following modules can be used for a modem connection to a PC:
1. IL-NT RS232
2. IL-NT RS232-485
The RS232 interface uses COM1 port of the controller.
If you have trouble with modem communication, an additional initialization string may be required. This
may be due to, for example, a national telephone network-specific feature. Use the setpoint
ModemIniString to add the necessary AT commands which will be sent to the modem during the
initialization. See the documentation of the modem for details.
NOTE:
Use the same kind of modem (e.g. analog, GSM or ISDN) as used on the controller also on the PC
side.
Recommended GSM modems
Siemens/Cinterion M20, TC35, TC35i, ES75, MC39 (baud rate 9600 bps)
Wavecom M1200/WMOD2 (baud rate 9600 bps)
Wavecom Maestro 20
Wavecom Fastrack M1306B (Fastrack M1206B is not recommended)
Falcom A2D
Modem setup procedure
Analog modems obviously do not require any setup. The only case in which setup could be necessary
is if the modem has been bought in a country with a telephony system different than the target country
where the modem will be used.
GSM modems need to be set up prior to using them with the controller. Use the gm_setup program
(installed together with LiteEdit) to perform initial setup of the modem. See the latest Inteli
Communication Guide (available on the ComAp web site) for details. The setup must be done while a
SIM card is inserted.
NOTE:
It is always recommended to use modems bought in and approved for the target country.
Internet connection
A PC can be connected to the controller also remotely via Ethernet (internet, intranet). An appropriate
Ethernet communication module must be used.
Use a plug-in communication module IB-Lite or IL-NT-GPRS to connect to the IA-NT controller via the
internet. The setpoint COM1 Mode must be set to the DIRECT position.

Using a web browser
The IB-Lite module with firmware version 1.1 and above makes it possible to use any web browser for
basic monitoring and adjustment of the controller. Direct your web browser to the IP address of the
module, e.g. http://192.168.1.254 and then enter the access code.
IB-Lite
HINT:
Setting the module up requires a certain familiarity with network administration. Ask your IT specialist
for assistance.
The default settings of the module are IP = 192.168.1.254, Netmask = 255.255.255.0 and
Gateway = 192.168.1.1. The default password for service webpages is “comap” (or “0”).
To restore the default settings, close the “restore default setting” jumper located on the module before
switching the controller on and remove it few seconds after the controller has been switched on.
HINT:
The default settings can be changed directly from the controller panel by pressing the “Page” button
and using ▼, ▲ and “Enter” to get to the “Comms Settings” menu (THIS APPLIES TO FIRMWARE VERSIONS
1.3 AND HIGHER).
Page 93
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 93
IA-NT- PWR-2.5-Reference Guide.pdf
Configuration
1. Plug the module into the controller and power the controller on.
2. Connect the module into your Ethernet network. If the default address does not match local
network parameters (i.e. the network segment does not use the IP range 192.168.1.xxx or the
IP 192.168.1.254 is occupied), connect the module directly to your PC using a cross-wired
cable. See details in the Installation chapter.
3. If you are connected directly, you have to change temporarily the IP address and subnet mask
of your PC Ethernet connection. Use the following settings: DHCP disabled, IP from the range
192.168.1.1 – 192.168.1.253 and subnet mask 255.255.255.0. After the IB-Lite setup is
finished, restore your PC setting back to the original values.
4. Start a web browser and direct it to http://192.168.1.254/sp_config.htm.
5. After a successful login the configuration page will be displayed.
6. It is recommended to change the user name and password and keep the new values
confidential.
7. Consult your IT specialist for proper IP settings.
8. Consult your e-mail provider for proper e-mail settings. Note that also most public SMTP
servers require authentication and e-mails must be sent from an existing address.
9. If you want to enable access only for clients with a specified IP address, tick the checkbox
“Trusted clients” and fill-in the allowed IP addresses.
HINT:
See also the latest LiteEdit Reference Guide (available on the ComAp web site) for more information
about IB-Lite setup.
Firmware upgrade
1. Follow steps 1–3 of the configuration procedure above.
2. Start a web browser and direct it to http://192.168.1.254/sp_fw_upld.htm.
3. After a successful login the configuration page will be displayed.
4. Press the button “Browse” and select the appropriate firmware file.
5. Press “Upload new firmware” button. After the firmware upload is finished, the module will
restart.
HINT:
Interrupting the upload will NOT cause any damage. Just repeat the upload again.
IL-NT-GPRS
CAUTION!
Any manipulation with plug-in module shall be done with disconnected power supply to both controller
and module. Power supply shall be switched on also is same time to both module and controller. Fail
to follow these instructions (power supply active only in controller or only in module) can lead to
module or controller failure!
Page 94
InteliATSNT PWR, SW version 2.5, ©ComAp – May 2015 94
IA-NT- PWR-2.5-Reference Guide.pdf
1. You will need one of supported ComAp controllers (IL-NT/IC-NT/ID-Lite/IA-NT), IL-NT-GPRS,
antenna, SIM card with GPRS service and optionally IL-NT-RS232 or IL-NT-S-USB module.
2. Contact SIM card operator for getting GPRS APN (APN = Access Point Name) name,
username and password. Example: APN Name = internet.t-mobile.cz, UserName = [blank],
Password = [blank].
3. Make sure SIM card does not require PIN code. If it does, it is possible to disable it in any
common network unlocked mobile telephone.
4. Power up the ComAp controller.
5. Enter correct APN Name, APN UserName and APN UserPass in controller’s setpoint group
Comms Settings. Set COM1 Mode = DIRECT. Comms settings as every setpoint group are
accessible by PAGE button from any measurement screen on controller. Setpoints can be set
on controller’s front panel keyboard or by LiteEdit 4.5 and higher.
6. Switch off ComAp controller.
7. Place the SIM card into slot on IL-NT-GPRS card, plug in the IL-NT-GPRS card into
communication slot on back side of ComAp controller.
8. Connect the antenna to designated SMA connector.
9. Connect power supply to IL-NT-GPRS module. It supports 8-36V DC voltage.
10. Power up the system.
11. Wait for approx 2 - 4 minutes for first connection of the system to AirGate. AirGate will
generate automatically the AirGate ID value. Then navigate to last of measurement screens
where you will find signal strength bar and AirGate ID identifier.
Once this AirGate ID is displayed, connection via AirGate was successful. This value will be
needed for LiteEdit or WebSupervisor connection. Kindly make a note for future reference.

AirGate Connection dialog in LiteEdit:
Add new gen-set dialog in WebSupervisor:
Should you encounter any troubles with connection, check the faultcodes on the same screen
and find detailed description in Diagnostic codes listed lower.
12. Open LiteEdit PC software or enter your WebSupervisor account at
http://websupervisor.comap.cz.
HINT:
For opening a new WebSupervisor account kindly send e-mail to admin.websupervisor@comap.cz
your Name, Login name, E-mail address and Timezone. We will create free account for you. Details
at: http://www.comap.cz/products/detail/WebSupervisor .
Communication is now ready for use.
HINT:
To reduce the data traffic over GPRS network you can set in setpoint group „Comms Settings“
the parameter „AirGate IP“ = 80.95.108.26. This will save significant data amount needed for
translation of Airgate server IP address. In case of changing the server IP address this settings has to
be updated or returned to default „airgate.comap.cz“.
HINT:
From its nature the GPRS connection can from time to time drop for a short time due to a number of
reasons affecting the cellular network. However the system is designed in the way that controller will
automatically reconnect back.

AirGate
technology for easy plug-and-play wireless communication is incorporated into the product. An
ordinary SIM card with GPRS service is suitable for this system. This overcomes problems with the
necessity for a special SIM card (fixed and public IP), firewalls and difficult communication settings.

Locate
The controller supports the technology for GSM localization using an IL-NT-GPRS
communication module. It is possible to view the localization in WebSupervisor.

Modbus protocol
The selection of the function of serial port is done via the setpoint COMx Mode in Basic settings
57600 bps, 8 data bits, 1 stop bit, no parity
Transfer mode RTU
Function 3 (Read Multiply Registers)
Function 6 (Write Single Register)
Function 16 (Write Multiply Registers)
The response to an incoming message is sent with minimum 4.096 ms delay after message
reception
The complete description of Modbus communication protocol can be found in Modbus Protocol
Reference Guide PI-MBUS-300 and Open Modbus Specification Release 1.0. Both documents are
available on the web.
Communication object vs. Register
All the data intended for communication has its representation as communication objects in the
controller. The communication object is represented by the n-byte array in the controller memory and
identified by the unique 16-bit communication object number. The register, according to Modbus
communication protocol, represents a two-byte data and in communication functions is referenced by
16-bit register address. Further in the description of communication functions the communication
object number will always be used as a register address and length of the communication object
will be expressed by number of registers. Just one communication object can be read or written
by one communication function.
NOTE:
To obtain communication object numbers it is possible to download the actual controller description
on-line from controller or from (ail) archive and use “export data” function from LiteEdit software.
HINT:
Do not write setpoints repeatedly (e.g. power control from a PLC by repeated writing of baseload
setpoint via Modbus) The setpoints are stored in EEPROM memory, which can be overwritten up to
105 times without risk of damage or data loss, but it may become damaged, when the allowed number
of writing cycles is exceeded!
