nd
Overcurrent Limit
A
0
When secondary volt/freq limits are active:
If the current goes above this limit, during the period
defined in
Overload Timeout
then a
Overcurrent
Load Dump
alarm will be generated.
If this parameter is 0 then Overcurrent check is
disabled.

2
nd
Mains Voltage Low
Limit
V
170
When secondary volt/freq limits are active:
If one of the mains phases goes under this limit, it
means that the mains are off and it starts the
transfer to the genset in
AUTO
mode.
(1)
2
nd
Mains Voltage High
Limit
V
270
When secondary volt/freq limits are active:
If one of the mains phases goes over this limit, it
means that the mains are off and it starts the
transfer to the genset in
AUTO
mode.

2
nd
Mains Frequency Low
Limit
Hz
45
When secondary volt/freq limits are active:
If the mains frequency goes under this limit, it
means that the mains are off and it starts the
transfer to the genset in
AUTO
mode.

2
nd
Mains Frequency
High Limit
Hz
55
When secondary volt/freq limits are active:
If the mains frequency goes above this limit, it
means that the mains are off and it starts the
transfer to the genset in
AUTO
mode.

nd
Genset Low Voltage
Shutdown Limit
V
190
When secondary volt/freq limits are active:
If one of the generator phase voltages goes under
this limit when feeding the load, this will generate a
GENSET LOW VOLTAGE
shutdown alarm
and the
engine will stop.
(2)
2
nd
Genset Low Voltage
Warning Limit
V
200
When secondary volt/freq limits are active:
If one of the generator phase voltages goes under
this limit when feeding the load, this will generate a
GENSET LOW VOLTAGE
warning.
(2)
2
nd
Genset High Voltage
Warning Limit
V
250
When secondary volt/freq limits are active:
If one of the generator phase voltages goes above
this limit when feeding the load, this will generate a
GENSET HIGH VOLTAGE
warning.
(2)
2
nd
Genset High Voltage
Shutdown Limit
V
260
When secondary volt/freq limits are active:
If one of the generator phase voltages goes over this
limit when feeding the load, this will generate a
GENSET HIGH VOLTAGE
alarm and the engine will
stop.
(1)
Voltage Unbalance
Warning Limit
%
0
If any of the phase voltages goes over (under) this
limit compared to the average voltage, then a
Voltage Unbalance Warning
will be generated.
If this limit is set to
0
, then the voltage unbalance
condition is not monitored.
(1)
Current Unbalance
Warning Limit
%
0
If any of the phase currents goes over (under) this
limit compared to the average current, then a
Current Unbalance Warning
will be generated.
If this limit is set to 0, then the current unbalance
condition is not monitored.
