DATAKOMDKG-705 User’s Manual11. LOAD SHEDDING / DUMMY LOADThe load shedding feature consists on the disconnection of the least crucial loads when the gensetpower approaches to its limits. These loads will be supplied again when the genset power falls below theprogrammed limit. The internal Load Shedding function is always active. Any of the auxiliary relays may beused as the load shedding output.The dummy load function consists on the connection of a dummy load if the total genset load isbelow a limit and to disconnection of the dummy load when the total power exceeds another limit.The dummy load function is the inverse of the load shedding function, thus the same output maybe used for both purposes.The parameters used in Load Shedding feature are:P_631 Load Shedding Low Limit: If the genset active power output goes below this limit, then the LoadShedding relay will be deactivated.P_632 Load Shedding High Limit: If the genset active power output goes above this limit, then the LoadShedding relay will be activated.705-UE.doc - 30 -

DATAKOMDKG-705 User’s Manual12. WEEKLY OPERATION SCHEDULEIn AUTO mode, the unit offers the capability of defining a weekly schedule of operation.The unit has 8 programmable turn-on/turn-off time pairs. These programmable parameters allowthe genset to operate automatically only in allowed time limits.In most applications, the genset is requested to operate only in working hours. Thanks to theweekly program feature unwanted operation may be prohibited.The weekly operation schedule is only active in AUTO mode. In other modes it will not affect thegenset operation.In AUTO mode, if the operation of the genset is disabled by the weekly schedule, then the AUTOled will flash (instead of a steady on state).Each turn-on/turn-off time is defined in 15 minute steps. These parameters are defined in theprogram group_4, parameters 400 to 415. An example setup may be as follows:P_400: Turn on: MO 07:00P_401: Turn off: MO 18:00P_402: Turn on: TU 07:00P_403: Turn off: TU 18:00P_404: Turn on: WE 07:00P_405: Turn off: WE 18:00P_406: Turn on: TH 07:00P_407: Turn off: TH 18:00P_408: Turn on: FR 07:00P_409: Turn off: FR 18:00P_410: Turn on: SA 07:00P_411: Turn off: SA 13:00P_412: Turn on: SA 13:00P_413: Turn off: SA 13:00P_414: Turn on: SA 13:00P_415: Turn off: SA 13:00If the same time is used in more than one parameter, only the first encountered one is considered.In the above example, SATURDAY 13:00 will be a turn-off time.705-UE.doc - 31 -
