PRINCIPIAL SCHEME OF A SITE IF NEUTRAL CONT = COMMON
NOTE:
As there is always a connection between the N and PE wires at the mains side the
generator neutral contactors are always open when the mains breaker is closed.
Setpoint: WatchedContr
This setpoint is used at redundant controller to specify the address of the related
main controller in CAN-based rendundant systems. Adjust this setpoint to 0 if the
controller is not used as redundant or if wired rendundancy system is used.
Group: Basic settings
Setpoint: Nomin Power
This setpoint is used for adjusting the gen-set nominal (rated) power, i.e. the
maximum allowed gen-set power level.
IS-NT controllers provide two independent power derating functions, which can be
used for derating of the gen-set according to an analog value (e.g. temperature).
See the setpoints Derating1 strt and Derating2 strt.
The nominal power or derated nominal power is used as the basis (100%) for gen-
set power protections, as the upper limit of the requested power in the parallel-to-
