(i.e. prior to the gen-set begun to ramp down or opened the 
GCB). If the load was 100% of the nominal power the length 
will be 100% of the setpoint Cooling time, if the load was 50% 
the length will be reduced to 50% etc...  
 
Setpoint: AfterCool time 
The setpoint is used to adjust the length of the aftercooling period, i.e. how long 
the cooling pump remains running after the gen-set has been stopped. 
 
Setpoint: Stop time 
This setpoint is used to adjust the time period the gen-set needs to stop 
completely. If the gen-set does not stop within this period the alarm Stop fail is 
issued. The setpoint also adjusts the minimal length of stop solenoid activation. 
See the output Stop Solenoid for more information. 
 
Setpoint: SDVentil time 
This setpoint is used to adjust the length of the preventilation phase at gas 
engines, i.e. if the setpoint Fuel solenoid is switched to GAS ENGINE. The 
preventilation phase is a period of cranking without opened gas valve which takes 
place prior to the first start attempt after a shutdown or after switching on the 
controller. 
The purpose of the preventilation phase is to clean the engine and exaust system 
from possible unburned gas.
