Parameter Definition Unit Min Max Factory
Set
Description
Instant Mains Dropout % 0 50 0
If the mains phase voltages are outside
limits, but not more than this parameter
(with reference to nominal voltage),
then the genset will run without
releasing the mains contactor. When
the genset is ready to take the load, the
load will be transferred.
If this parameter is set to zero then the
mains contactor is immediately released
at mains failure.
Mains Frequency Low
Limit
% F-100 F+100 F-10%
If the mains frequency goes under this
limit, it means that the mains are off and
starts the transfer to the genset in
AUTO mode. The value is defined with
reference to Nominal Frequency.
Mains Frequency High
Limit
% F-100 F+100 F+10%
If the mains frequency goes over this
limit, it means that the mains are off and
starts the transfer to the genset in
AUTO mode. The value is defined with
reference to Nominal Frequency.
Mains Frequency Fail
Timer
sec 0 10 1
If the mains frequency goes outside of
the limits during this timer, it means that
the mains are off and starts the transfer
to the genset in
AUTO mode.
Genset Low Voltage
Warning Limit
% V-100 V+100 V-15%
If one of the genset phase voltages goes
under this limit when feeding the load,
this will generate a
GENSET LOW
VOLTAGE warning.
Genset Low Voltage
Shutdown Limit
% V-100 V+100 V-20%
If one of the genset phase voltages goes
under this limit when feeding the load,
this will generate a
GENSET LOW
VOLTAGE shutdown alarm and the
engine will stop.
Genset High Voltage
Warning Limit
% V-100 V+100 V+15%
If one of the genset phase voltages goes
over this limit when feeding the load, this
will generate a
GENSET HIGH
VOLTAGE warning.
Genset High Voltage
Shutdown Limit
% V-100 V+100 V+20%
If one of the genset phase voltages goes
over this limit when feeding the load, this
will generate a
GENSET HIGH
VOLTAGE shutdown alarm and the
engine will stop.
Genset Voltage Fail
Timer
sec 0 10 1
If at least one of the genset phase
voltages goes outside of the limits
during this timer, a genset voltage fault
will occur.
