Hint:
If the IDLE function not supported on the governor, set the Idle Time nevertheless to minimum 5s to
avoid Underspeed possibly caused by instability of the engine short after start.
Min Stab Time [s]
Minimum time after reaching of defined level of RPM to the closing GCB.
Step: 1s
Range: 1 – 300 (Max Stab Time) s
Max Stab Time [s]
Maximum time after start to get proper voltage level of the generator.
Step: 1s
Range: 1 (Min Stab Time) – 300 s
Hint
:
When generator voltage within Max Stab Time does not reach defined limits (Generator protection
group) , an alarm occurs and the gen-set will shut down
Cooling Time [s]
Runtime of the unloaded gen-set to cool the engine before stop.
Step: 1s
Range: 0 – 3600 s
Hint
:
Cooling is executed at nominal speed and generator protections are active.
Stop Time [s]
Under normal conditions the engine must certainly stop within this period. The period starts by issuing
stop command.
Step: 1s
Range: 0 – 240 s
Hint
:
Stop of engine is detected when all following conditions are met: RPM <2, Oil pressure < Starting Oil P
Generator voltage < 10 VAC and D+ input isn’t active.
Stop fail is detected when there is difference between those conditions, e.g RPM<2 and Generator
voltage > 10V.
Fuel Solenoid [ DIESEL / GAS ]
Determines behavior of the Binary output FUEL SOLENOID.
DIESEL: Output closes 1 sec before Binary output STARTER.
The output opens if Emergency Stop comes or Cooled gen-set is stopped and in pause
between repeated starts.
