Setpoint: Cooling time
This setpoint is used to adjust the length of the Cooling phase, which takes place
after the gen-set has been unloaded (GCB opened) and before it is stopped. The
cooling phase can be performed either at nominal or at idle speed. See the
setpoint Cooling speed.
If the cooling phase length optimalization is enabled, the actual length depend on
the actual genset load in the moment the stop sequence was started. See the
setpoint Cooldown optim.
Setpoint: CoolDnAfterBOC
The setpoint selects the controller behavior in cooling phase after a BOC alarm:
The controller behaves as usually, e.g. the cooling phase lasts
for period adjusted by the setpoint Cooling time and then the
gen-set is stopped.
The cooling phase is not finished automatically when the
Cooling time elapses. The gen-set remains in cooling until
another event changes the it's state, e.g. it is 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.
Setpoint: Cooldown optim
This setpoint enables optimalization of the cooling phase length based on the
previous gen-set load.
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
