6.6.9 Fan priority update
In parameter 6562, the priority update rate (the hours between priority changes) is selected:
If the fan priority update is set to 0 hours, the priority order is: Fan A, Fan B, Fan C, Fan D.
6.7 Derate genset
The derate function reduces the maximum output power of the genset when specific conditions require this. For example, if the
ambient temperature increases so much that the cooling water coolers do not have enough cooling capacity. If the genset is not
derated, there can be alarms and/or a shutdown. Three, independent derate functions are available.
The derating is based on the nominal power.
