Description of the contr oller system
NT family controllers are comprehensive AMF-controllers for single and multiple generating sets
operating in stand-by or parallel modes. Synchronizer, isochronous load sharer, Mains and Generator
protections allow for a total integrated solution for gen-sets in stand-by and parallel modes with
multiple engine support.
NT family controllers (IG-NT, IG-NTC, IG-NT-BB, IG-NTC-BB, IS-NT-BB, IS-NTC-BB, IM-NT, IM-NTBB and IM-NTC-BB) could be equipped with a powerful colour display showing icons, symbols and
bar-graphs for intuitive operatio n, w hich sets , tog ether with high functionality, new standar ds in gen-set
controls.
The controller automatically starts the gen-set, closes the gen-set C.B. when all conditions are met,
then stops the engine on external signal or by pressing push buttons.
Parallel to Mains operation can be achieved without additional HW. Forward and reverse
synchronizing, Mains protection including vector shift, load and power factor control, earth fault
protection are the major functions provided. Interfacing to foreign synchronizers and load sharers is
supported.
The key feature of NT family controllers is their easy-to-use installat ion and operation. Predefined
configurations for typical applications are available as well as user-defined configurations for special
applications.
Conformity declaration
Following described machine complies with the appropriate basic
safety and health requirement of the EC Low Voltage Directive
2006/95/EC and EC Electromagnetic Compatibility Directive
2004/108/EEC based on its design and type, as brought into circulation
by us.

When to use GCB ON/OFF button?
The button is disabled in AUT mode.
In MAN and TEST modes it is enabled, but before closing of the circuit beaker,
generator voltage and frequency must be within limits. The controller has internal
protection to avoid the breaker closure without synchronizing.
The controller recognizes automatically:
• if there is mains / bus voltage and the gen-set shall be synchronized before
closing the GCB
• or if there is no voltage on the bus and the GCB can be closed without
synchronizing.
When to use MCB ON/OFF button?
The button is disabled in AUT mode.
Use this button in MAN or TEST mode to close or open the MCB. Be careful while
doing this, because you can disconnect the load from the mains!!!

To enter or change password
of selected user press Enter.
Users and Passwords
Up to 8 users can be defined in the system. Every user has it’s own defined level of
access rights. There are seven levels of password protection.
User O – Administrator has alw ays level 7.
Hint:
The lock mark appears before a set point name (on controller screen) if the
setpoint is password protected.
The lock mark is removed only when the password is set from controller’s front panel.
The lock mark is still visible on controller screen even if the password is set from
different terminal.
Even though one level may have been set from the front panel, the affected set
points are not accessible from InteliMonitor (direct or Modem) until this level is set in
InteliMonitor (direct or Modem). Set point screen ope ne d fro m fro nt pan el is
automatically closed 15 minutes after the last key has been pressed.
It is possible to protect remote Start, Stop, GCB and MCB commands from
InteliMonitor. This seven level command protection can be c on fig ured in GenConfig.
EnterPassword
Password is a five-digit number (0 - 65535). Only setpoints associated with the
entered password level can be modified.
Use ↑ or ↓ to select the desired password and then press ENTER.
Use ← or → to move the value by 5% of the range.
There are four gen-set operation modes: OFF - MAN – AUT – TEST in SPtM
application. There are t hr ee gen-set operation modes: OFF - MAN – AUT in SPI,
COX and MINT application.
To select the mode use MODE→ or ←MODE.
OFF mode
• No start of the gen-set is possi bl e. Outputs STARTER, GCB CLOSE/O PEN and
FUEL SOLENOID are not energ i z ed.
• No reaction if buttons START,STOP,GCB ON/OFF are pressed.
• MCB behavior depends on AMF settings: MCB opens on setpoint:
MAINSFAIL: When power-cut comes, MCB opens. After Mains returns, MCB
closes with MCB close del.
GEN RUNNING:When power-cut comes, MCB stays closed until the gen-set
starts and produces voltage within limits.
MAN mode
1) To start the gen-set press START.
2) When the generator voltage is within limits (adjusted in the setpoints group
Generator protections) GCB green LED on the front panel lights.
3) Press GCB ON/OFF to close the GCB. If the generator voltage is out of the limits,
controller does not respond to the GCB ON/OFF .
a) If controller detects dead bus, immediately closes GCB OPEN/CLOSE output.
b) If controller detects voltage on the bus, starts synchronizing.
4) To stop the engine press STOP
a) controller unloads the gen-set, opens GCB CLOSE/OPEN. Unloading is active
only when binary input MCB feedback is closed or other gen-set is connected to
bus. In other case GCB CLOSE/OPEN opens immediately.
b) Gen-set is cooled down and stopped.
Hint:
Controller does not respond to external signals and/or conditions. The gen-set is fully
in manual control; there is no automatic way to stop it (except protections). The genset stays running until STOP button is pressed.
Controller does not take place in Power management in MINT application
AUT mode
Gen-set is controlled based on external signals (Rem start/stop, Sys start/stop) or
conditions (AMF, Peak shaving, Power management system, …).
Hint:
Engine does not stop, if other condition for automatic starts is active.
Example: If peak stop condition occurs, but REMOTE START/STOP is active, engine
stays running.
Controller does not respond to GCB ON/OFF , MCB ON/OFF, STOP, START
buttons and corresponding remote InteliMonitor or Modbus commands.
Set Basic setting: FltRes GoToMAN = ENABLED to avoid automatic engine start
when pressing FAULT RESET after Shut down or Slow stop alarm.
Engine can start automatically without warning when pressing FAULT RESET after
shut down alarm.
TEST mode (SPtM only)
Use TEST mode for Gen-set start test if the Mains is OK or to transfer the load to the
gen-set when Mains fail is announced in advance.
Hint:
The controller does not respond to GCB ON/OFF , STOP, START in Ret from test =
AUTO.
Engine automatically starts, when TEST mode is selected.
Engine can start automatically without warning when pressing FAULT RESET after
shut down alarm.
SEM mode
START – starts the gen-set.
• The controller closes GCB to dead bus.
• If the Mains is within limits and MCB is closed, the controller starts
synchronizing and closes GCB when synchronizing conditions are met. Genset remains running in parallel.
• If Mains failure is recognized during parallel operation the controller opens
MCB.
• After Mains recovers the controller synchronizes MCB and returns to parallel
operation
STOP – unloads the gen-set, opens GCB, cools down the engine and stops.
AMF function – If the Mai ns fails whi l e the gen-set is not running, the controller
automatically starts and closes GCB.
Other automatic starts/stops (e.g. due to peak shaving, BI Rem start/stop activation)
are not performed in SEM mode.
Baseload
Process control: Load ctrl PtM = BASELOAD
Gen-set power is kept at value given by Process control:Base load setpoint.
Gen-set power is controlled to keep the import load at the level given by setpoint
Process control:Import load value.
Controller measures Import/Export value via current transformers connected to
In/Im3 terminal. The value of L3 is then multiplied by 3 to give an estimation of the
actual Imp/Exp.
