Set points related to the stop sequence
Stop failure
4580 Stop failure
A stop failure alarm will appear if the primary running feedback or the generator voltage and frequency are
still present after the delay in this menu has expired.
Stop
6210 Stop
Cooling down: The length of the cooling down period.
Extended stop: The delay after the running feedback has disappeared until a new start sequence is allowed.
The extended stop sequence is activated any time the Stop button is pressed.
Cool down controlled by engine temperature: The engine temperature-controlled cool down is to ensure that
the engine is cooled down below the set point in menu 6214 "Cool down temperature" before the engine is
stopped. This is particularly beneficial if the engine has been running for a short period of time and therefore
not reached normal cooling water temperature, as the cool down period will be very short or none at all. If
the engine has been running for a long period, it will have reached normal running temperature, and the cool
down period will be the exact time it takes to get the temperature below the temperature set point in menu
6214.
If, for some reason, the engine cannot get the temperature below the temperature set point in 6214 within the time limit in parameter
6211, the engine will be shut down by this timer. The reason for this could be high ambient temperature.
INFO
If the cooling down timer is set to 0.0 s, the cooling down sequence will be infinite.
INFO
If the cooling down temperature is set to 0 deg., the cooling down sequence will be entirely controlled by the timer.
INFO
If the engine stops unexpectedly, please refer to the chapter "Running feedback".
