Description
(2)
Current Transformer
Ratio
A
500
This is the rated value of the current transformer.
The secondary of the transformer will be 5 Amps.
(2)
Overcurrent Limit
A
0
If the current goes above this limit, during
Overload
Timeout
then a
Overcurrent Load Dump
alarm will be
generated. If this parameter is 0 then Overcurrent check
is disabled.
(2)
Power x 3
-
0
If this parameter is set to 1, then the power read from
the genset phase will be displayed as multiplied by 3.
(2)
Excess Power Limit
KW
0
If the active power goes above this limit, during
Overload Timeout then an
Excess Power Load Dump
alarm will be generated. If this parameter is 0 then
Excess Power check is disabled.
(2)
Overload Timeout
sec
5
This is the period between the current or active power go
over the limits and
OVERCURRENT
or
EXCESS
POWER
Load Dump alarms occur.
This is also the period between the frequency goes out
of the limits and
OVERSPEED
or
UNDERSPEED
alarms
occur.
This is also the period between the genset voltage goes
out of the limits and
HIGH VOLTAGE
or
LOW
VOLTAGE
alarms occur.
(1)
Mains Voltage Low Limit
V
170
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)
Mains Voltage High
Limit
V
270
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)
Mains Frequency Low
Limit
Hz
45
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)
Mains Frequency High
Limit
Hz
55
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.
(2)
Genset Low Voltage
Shutdown Limit
V
190
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)
Genset Low Voltage
Warning Limit
V
200
If one of the generator phase voltages goes under this
limit when feeding the load, this will generate a
GENSET
LOW VOLTAGE
warning.
(2)
Genset High Voltage
Warning Limit
V
250
If one of the generator phase voltages goes above this
limit when feeding the load, this will generate a
GENSET
HIGH VOLTAGE
warning.
(2)
Genset High Voltage
Shutdown Limit
V
260
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.
