If, for some reason, the engine cannot get the temperature below the temperature
setpoint in parameter 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.
NOTE: If the cooling-down timer is set to 0.0 s, the cooling-down
sequence will be infinite.
NOTE: If the cooling-down temperature is set to 0 deg., the
cooling-down sequence will be entirely controlled by the timer.
Breaker Sequences
The breaker sequences will be activated depending on the selected mode:
Mode Genset mode Breaker control
Auto All Controlled by the unit
Manual All Push-button, M-Logic, Modbus, Digital input
Block All Controlled by the unit
Before closing the breakers, it must be checked that the voltage and frequency are OK.
