7.9 System load control modes
HINT
If you need more information on how to choose suitable load control mode, please refer to the chapter
6.8.7 Managing system load control modes.
System load control modes are determined by setpoints ProcessControl:Mload ctrl PtM and
SysLdCtrl PtM.
If ProcessControl:#SysLdCtrl PtM is set to BASELOAD, then Gen-set group requested load is not
determined by InteliMains but it is given by setpoint ProcessControl:#SysBaseLoad regardless of
ProcessControl:Mload ctrl PtM setting.
