Active Power Ramp
(kW/sec)
%
0
100.0
1.0
In case of a soft transfer, the load’s active
power (KW) will be transferred to the
mains with this rate vice versa.
Reactive Power Ramp
(kVAr/sec)
%
0
100.0
1.0
In case of a soft transfer, the load’s
reactive power (kVAr) will be transferred
to the mains with this rate vice versa.
Ramp On High Limit
%
0
100.0
80.0
If multi genset system total active power
goes over this limit while soft transferring
to mains load contactor will be de-
energized.
Ramp Off Low Limit
%
0
100.0
10.0
If multi genset system total active power
goes under this limit while soft
transferring to mains load contactor will
be de-energized.
Active Power Share G
Gain

200
20
This parameter defines the reaction
speed of the kW control during soft
loading. The standard value for this
parameter is %20. 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.
Reactive Power Share G
Gain
%
0
200
20
This parameter defines the reaction
speed of the kVAr control during soft
loading. The standard value for this
parameter is %20. 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.
Nominal Frequency G
Gain
%
0
200
8
This parameter governs the nominal
frequency catching of the master unit.
If this parameter is increased, the
operation will be faster but unstable. If it
is decreased, the operation will be slower
but more stable. The best setting is the
fastest stable operation.
Nominal Voltage G Gain
%
0
200
8
This parameter governs the nominal
voltage catching of the master unit.
If this parameter is increased, the
operation will be faster but unstable. If it
is decreased, the operation will be slower
but more stable. The best setting is the
fastest stable operation.
Multi Genset Delayed
Start
%
0
120
80
If the total active load is above this level
for the period defined in Multi Genset
Run/Stop Delay, the slave genset will
start, synchronize and share the load.
This parameter is defined as a
percentage of the Genset Power Rating
parameter.
Multi Genset Quick Start
%
0
120
90
If the total active load is above this level,
the slave genset will start, synchronize
and share the load without delay. This
parameter is defined as a percentage of
the Genset Power Rating parameter.
