DATAKOMDKG-705 User’s ManualGroup Parameter DefinitionUnit Min Max Description5 509 Gen. Contactor Timer Sec 0.5 120 This is the period after the mainscontactor has been deactivated andbefore the generator contactor has beenactivated.5 510 Overcurrent Limit Amp 20 2500 If the current is over this limit, anAlternator Overcurrent alarm will begenerated after the Overcurrent Timer(P511) period.5 511 Overcurrent Timer /Excess Power TimerSec 1 20 This is the period between the currentgoes over the Overcurrent Limit (P510)and the Alternator Overcurrent alarmoccurs.This is also the period between the gensetpower goes over the Excess PowerLoad Dump Limit (P617) and the GenExcess Power Load Dump occurs.5 512 Mains Low Limit Volt 0 240 If one of the mains phases goes underthis limit, it means that the mains areoff and it starts the transfer to thegenset in AUTO and TEST modes.5 513 Mains High Limit Volt 100 300 If one of the mains phases goes overthis limit, it means that the mains areoff and it starts the transfer to thegenset in AUTO and TEST modes.5 514 Gen Low Limit Volt 60 240 If one of the generator phase voltagesgoes under this limit when feeding theload, this will generate a Genset LowVoltage Alarm and the engine will stop.5 515 Gen High Limit Volt 100 300 If one of the generator phase voltagesgoes over this limit when feeding the load,this will generate a Genset High VoltageAlarm and the engine will stop.5 516 Low Freq. Shutdown Hz 10 60 If the genset frequency goes under thislimit for Frequency Timer (P520) period,this will generate a Genset Under-Frequency Alarm and the engine willstop.5 517 Low Freq. Warning Hz 10 60 If the genset frequency goes under thislimit for Frequency Timer (P520) period,this will generate a Genset Under-Frequency Warning.5 518 High Freq. Shutdown Hz 40 150 If the genset frequency goes over this limitfor Frequency Timer (P520) period, thiswill generate a Genset Over-Frequency Alarm and the engine willstop.5 519 High Freq. Warning Hz 40 150 If the genset frequency goes over this limitfor Frequency Timer (P520) period, thiswill generate a Genset Over-FrequencyWarning.5 520 Frequency Timer /Engine rpm TimerSec 1 20 This is the period between the gensetfrequency or engine rpm goes out of thelimits and an alarm occurs.5 521 Horn Timer Sec 0 240 This is the maximum period during whichthe alarm relay output may stay active.If the period is set to 0, this will meanthat the delay is unlimited.705-UE.doc - 37 -
