The 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 order
check should be disabled only in single phase gensets.
P_A07 Synchronization Fail Timeout: If the phase and voltage synchronization is not successful before
the expiration of this timer, then the DKG-705 renounces the No Break Transfer and makes a Transfer
with Interruption.
P_A09 Contactor Timeout: This is the maximum time duration in which both contactors are active in case
of No Break Transfer.
P_A10 Max Frequency Difference: This is the maximum difference between mains and genset
frequencies to enable a NO Break Transfer.
P_A11 Max Voltage Difference: This is the maximum difference between the mains phase-R and the
genset 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 and
the 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.
