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.
