The controller behaves as usually, e.g. the cooling phase
lasts for period adjusted by the setpoint
then the gen-set is stopped.
The cooling phase is not finished automatically when the
Cooling time

manually stopped. If the gen-set is in AUT mode and the
alarm is not active and has been reset the gen-set
returns to loaded state automatically.
The length of the cooling phase is given by the setpoint
Cooling time regardless of the previous gen-set load.
The length of the cooling phase is linearly reduced according
to the gen-set load in the moment the stop sequence started
(i.e. prior to the gen-set begun to ramp down or opened the
GCB). If the load was 100% of the
