Mode and function description
There are four gen-set operation modes: OFF - MAN – AUT – TEST in SPtM
application. There are three 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 possible. Outputs STARTER, GCB CLOSE/OPEN and
FUEL SOLENOID are not energized.
• 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 gen-
set 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.
