Derating1 end
Derating2 end
Ending value for power limitation – at this value the gen-set power is limited to DeratedX pwr value and it
won't go lower for higher input values.
The setpoint actual physical dimension is given by the related analog input and the value assigned to it.
Step: 1 X
± 32000 X
Range:
Force value possibility: Yes
Hint:
To record the power derating activity into the History:
-Configure the binary output Derating X act to a virtual periphery input.
-Configure either "History record" or "Warning"-type alarm to this input to record power derating
activity in History and optionally to indicate it in Alarmlist.
Derated1 pwr
Derated2 pwr
The ratio of decreasing of the gen-set nominal power at DeratingX end level.
Step: 1 % of Nomin power
Range: 0 - 100 % of Nomin power
Force value possibility: Yes
Hints:
DeratedX pwr = 90% means the nominal power reduction to 90%, not by 90%.
Derating ratio is set to zero and functions are not active when Analog inputs PowerDeratingX are not
configured (e.g. in default configuration).
When Power derating function is active, the generator nominal power is decreased to DeratedX pwr and so
Overload protection (BOC Overload) is based on this Derated power!
The generator nominal power is reduced according to the bigger restriction – the more reduced channel out
of the two.

TempByPwr Treq
Requested temperature value for temperature control by generator power.
Before use, you have to configure the analog input LdCtrl:TbyPwr.
