Max Phase
Difference
Deg.
0
20 This is the maximum phase difference between
the mains phase-R and the genset phase-U to
enable a
NO Break Transfer
. Note that the
DKG-705 adjusts the
GOV
output to bring the
genset to the same phase with the mains.

Governor Start
-
0
255 This is the rest value of the governor control
output. Always set this value to 128, which is
the mid-course. However, if needed, engine
frequency adjustment may be made through
this parameter.

A14
AVR Start
-
0
255 This is the rest value of the AVR control output.
Always set this value to 160. However, if
needed, genset voltage adjustment may be
made through this parameter.

Frequency Lock
Gain
-
0
255 This parameter defines the reaction speed of
the governor output to phase differences
between genset and mains phases during
synchronization. The standard value for this
parameter is 32. But it must be readjusted for
the engine during manufacturing. If this
parameter is too high, a phase oscillation may
occur. If it is too low, the phase locking will be
slower.

A16
AVR Gain
-
0
255 This parameter defines the reaction speed of
the AVR output to voltage differences between
genset and mains phases during
synchronization. The standard value for this
parameter is 64. But it must be readjusted for
the genset during manufacturing. If this
parameter is too high, a voltage oscillation may
occur. If it is too low, the voltage matching will
be slower.

0
255 This parameter defines the reaction speed of
the KW control during soft transfer. The
standard value for this parameter is 64. But it
must be readjusted for the genset during
manufacturing. If this parameter is too high, a
KW oscillation may occur. If it is too low, the
KW transfer will be slower.

0
255 This parameter defines the reaction speed of
the KVAr control during soft transfer. The
standard value for this parameter is 64. But it
must be readjusted for the genset during
manufacturing. If this parameter is too high, a
KVAr oscillation may occur. If it is too low, the
KVAr transfer will be slower.
