General Guidelines
What is in this manual?
This manual describes the InteliATS
NT
PWR (IA-NT-PWR) software, which is designed for automatic
transfer switch applications and provides general information on how to install and operate the
InteliATS
NT
controller.
This manual is dedicated for
• Automatic transfer switch panel builders
• Operators of remote gen-sets (started remotely from InteliATS
NT
)
• For everybody who is concerned with installation, operation and maintenance of the gen-set
InteliATS controller SW and HW versions compatibility
Software InteliATS
NT
v. 1.0 is compatible with the InteliATSNT hardware v. 1.3.
There are two modifications of the InteliATS
NT
HW - STD and PWR and two modifications of the
InteliATS
NT
SW – STD and HW which together with the appropriate archive file (IA-NT-STD-X.X.AIL or
IA-NT-PWR-X.X.AIL) form the InteliATS
NT
PWR or STD controller.
Beside that the InteliATS
NT
1.0 software is compatible with IL-NT AMF HW 1.3 too, which is used
when a low temperature ATS application is needed. In this case the InteliATS
NT
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 any
combination. 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.
WARNING!

Description
Description of the controller system
InteliATS
NT
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 change over for both generator and mains contactors. The gen-set requires a
remote start type control unit (e.g. the ComAp InteliLite
NT
MRS 10 controller), at least a key-start box
with an external input for the start/stop signal.
InteliATS
NT
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.
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
Example application
InteliATSNT PWR, SW version 1.0, ©ComAp – March 2009 8
IA-NT- PWR-1.0-Reference Guide R1.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 standart
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.

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).
