Fault codes

CodeMeaning
Battle short modeSome shutdown faults are bypassed
DerateOutput power of the genset is reduced in response to a fault condition
Emergency stopAnnunciated whenever either emergency stop signal is received from external switch

Symptoms & remedies

SymptomRemedy
Battle short modeIf a bypassed shutdown fault occurs, the fault code and description will still be annunciated, but the genset will not shutdown. This will be followed by a fail to shutdown fault.
DerateThe Derate function reduces output power of the genset in response to a fault condition. If a Derate command occurs while operating on an isolated bus, the control will issue commands to reduce the load on the genset via contact closures or Modbus. If a Derate command occurs while in utility parallel mode, the control will actively reduce power by lowering the base load kW to the derated target kW.
Emergency stopAnnunciated whenever either emergency stop signal is received from external switch.
