OverldStrtEval
Min Power PtM [ % ] (FV)
Minimum Power in Parallel to the Mains is the minimal value of the gen-set power in parallel to the mains.
Gen-set is never loaded below this level (even if the active load control loop requests a lower level). There is
no indication or alarm when Min Power PtM level is reached.
Step: 1 % of Nomin power
Range: 0 – 100 % of Nomin power
Force value possibility: Yes
Hint:
If the setpoint Base load is lower than setpoint Gener protect: Min power PtM, the gen-set requested load is
set to Gener protect: Min power PtM.
