DKG-705 AUTOMATIC MAINS FAILURE AND REMOTE START ...

DATAKOMDKG-705 User’s ManualThe DKG-705 has a set of programmable parameters to define the No Break Transfer operation.These parameters are:P_512 Mains Low Limit: Each of the mains phase voltages must be over this limit.P_513 Mains High Limit: Each of the mains phase voltages must be below this limit.P_514 Gen Low Limit: Each of the genset phase voltages must be over this limit.P_515 Gen High Limit: Each of the genset phase voltages must be below this limit.P_516 Low Frequency Shutdown: The genset frequency must be over this limit.P_517 Low Frequency Warning: The genset frequency must be over this limit.P_518 High Frequency Shutdown: The genset frequency must be below this limit.P_519 High Frequency Warning: The genset frequency must be below this limit.P_522 Mains Frequency Low Limit: The mains frequency must be over this limit.P_523 Mains Frequency High Limit: The mains frequency must be below this limit.P_A00 No Break Transfer: This parameter enables/disables the No Break Transfer feature.P_A06 Ignore Phase Order: If set, this parameter will disable the phase order check. The phase ordercheck should be disabled only in single phase gensets.P_A07 Synchronization Fail Timeout: If the phase and voltage synchronization is not successful beforethe expiration of this timer, then the DKG-705 renounces the No Break Transfer and makes a Transferwith Interruption.P_A09 Contactor Timeout: This is the maximum time duration in which both contactors are active in caseof No Break Transfer.P_A10 Max Frequency Difference: This is the maximum difference between mains and gensetfrequencies to enable a NO Break Transfer.P_A11 Max Voltage Difference: This is the maximum difference between the mains phase-R and thegenset phase-U voltages to enable a NO Break Transfer.P_A12 Max Phase Difference: This is the maximum phase difference between the mains phase-R andthe genset phase-U to enable a No Break Transfer.P-760 to P_766: These parameters define the function of digital input_6.P-770 to P_776: These parameters define the function of digital input_7.705-UE.doc - 24 -
