3. General Guidelines
3.1.Safety Instructions
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTION - This manual contains important instructions for IGS-NT
controllers family that shall be followed during installation and maintenance of the Inteli NT
genset controllers.
It is intended for use by Gen-set control panel builders and for everybody who is concerned
with installation, operation and maintenance of the gen-set.
WARNING
Remote control
The controller can be remotely controlled. In the event that maintenance needs to be done
to the gen-set, check the following to ensure that the engine cannot be started.
To be sure:
Disconnect remote control via RS232 or another communication line
Disconnect input REMOTE START/STOP
or
Disconnect output STARTER and outputs GCB CLOSE/OPEN and MCB CLOSE/OPEN.
Be aware the unqualified manipulation can disconnect the object from the power supply
source.
CAUTION!
The controller contains a large number of configurable setpoints, because of this it is
impossible to describe all applications. Controller functions are subject to change from SW
version to SW version. This manual only describes the product and is not guaranteed to be set
for your application on arrival.
!!! CAUTION !!!
Dangerous voltage
The terminals for voltage and current measurement should never be touched.
Properly connect the grounding terminals.
Do not disconnect the Controller CT terminals for any reason.
Adjust set points
All parameters are djusted to their typical values. But the set points in the “Basic settings”
settings group !!must!! be adjusted before the first startup of the gen-set.
!!! WRONG ADJUSTMENT OF BASIC PARAMETERS CAN DESTROY THE GEN-SET !!!
The following instructions are for qualified personnel only.
To avoid personal injury do not perform any action not specified in this User guide !!!

IGS-NT Installation Guide
13
WARNING –VERY IMPORTANT !!!
Be aware that the binary outputs can change state during and after software
reprogramming. Before the controller is used again ensure that the proper
configuration and setpoint settings are set in the controller.
Every time you want to disconnect following controller terminals:
Mains voltage measuring and / or
Binary output for MCB control and / or
MCB feedback
Be aware that the MCB can be switched off and gen-set can start !!!
Switch controller to MAN mode and disconnect the Binary outputs Starter and Fuel or press
EMERGENCY STOP button to avoid unexpected automatic start of gen-set and GCB closing
during any work or maintenance on the gen-set or switchboard.

4. Marine Application Notes
The IGS-NT system and components can be used as Control, Monitoring and Protection for
single and multiple generator applications according to Marine Type Approval Regulation
Controller is tested and approved:
For location in Machinery spaces and Control room –Location class B.
According the EMC rules for general power distribution zones.
4.1.Safety requirements
Additional, independent safety and protection devices are necessary to meet safety
requirements of Rules and Regulations of Marine Classification Societies. The sensors and
circuits utilized for the second stage alarm and automatic shutdown are to be independent of
those required for the first stage alarm (LR Rulefinder 2008 - V9.10).
NOTE:
The project designer is responsible to follow Marine regulations in project design wiring and
InteliGen-NT or InteliSys-NT controller configuration and setpoint setting.
Usually is necessary to use additional, independent equipment for Emergency stop,
Overspeed, Low oil pressure and Overcurrent protection.
Oil mist and engine bearing temperature monitoring are to be provided when arrangements
are fitted to override the automatic shutdown for excessive reduction of the lubrication oil
pressure (or for engines above 2250 kW). The Overriding of this protection is to be
independent.
Required alarms and safeguards for auxiliary engines.
Lubrication oil inlet temperature high
Lubrication oil inlet pressure low
Coolant outlet temperature high
Coolant pressure or flow low
Exhaust gas temperature high
The maximal wire length for Binary (Analog) inputs and outputs should be less than 10
meters, otherwise the separation relay or additional protection has to be used.

4.1.1. Power supply
To have full Surge protection ±2kV for controller power supply terminals the external
component (e.g. two VSSC4 MOV 48VAC/DC from Weidmueller for DIN rail) has to be connected.

The I-LBA (low battery adaptor) module is to be used when power supply voltage dip up to
200ms is required. The up to 100ms supply voltage dip is acceptable by IG-NT or IS-NT
controller itself.

4.2.Default configuration
CAUTION!
Use the default IG-MINT-Marine-2.3.ant (or higher) or IS-MINT-Marine-2.3.ant (or higher) to
avoid incorrect system setting and configuration.
Default configuration can be modified using the GenConfig-2.3 (or higher) PC tool. Please
take care of following items that are included in default configuration file:
The function "Virtual Peripheries" shall not be used for marine application.
An automatic start of the generator after acknowledgement of alarm shall be prevented
(Basic settings: FltResGoToMAN = ENABLED).
Common alarm contacts interfacing the machinery alarm system shall be re-triggered in
case of occurring new alarm" (BO5 = Alarm flashing).
4.2.1. Override function
The “Sd override” (Shut-down override) function is included in default configuration on Binary
input BI7. Active Override is indicated by a " !" mark on the display and on Binary output BO4
Common SdOvr.
The default Override function blocks all protections except the Overspeed, Emergency stop
and all Analog or Binary protections configured as SD Override.
HINT
It is strongly recommended to modify names of such values to begin or finish with letters
SDO –e.g. WaterTemp SDO.
Use internal PLC function when the independent override protection e.g. for Bearing
temperature is required.
