Description
(2)
Current Transformer
Ratio
A
500
This is the rated value of current transformers.
All transformers must have the same rating.
The secondary of the transformer will be 5 Amps.
(2)
Overcurrent Limit
A
0
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)
Excess Power Limit
KW
0
If the active power goes above this limit, during the
period defined in 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.
(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.
(2)
Low Battery Voltage
Warning
V
9.0
If the battery voltage falls below this limit, this will
generate a
LOW BATTERY
warning.
(2)
High Battery Voltage
Warning
V
31.0
If the battery voltage goes over this limit, this will
generate a
HIGH BATTERY
warning.
(2)
High Battery Voltage
Shutdown
V
33.0
If the battery voltage goes over this limit, this will
generate a
HIGH BATTERY
shutdown
alarm and
the engine will stop.
(1)
Mains Waiting Timer
min
0.5
This is the time between the mains voltages
entered within the limits and the generator contactor
is deactivated.
(2)
Genset Contactor Timer
sec
1
This is the period after the mains contactor has been
deactivated and before the generator contactor has
been activated.
(2)
Mains Contactor Timer
sec
1
This is the period after the generator contactor has
been deactivated and before the mains contactor has
been activated.
(2)
Mains Phase Order
Enable
-
0
0:
mains phase order checking disabled
1:
if mains phase order is faulty, then a warning is
given and mains contactor deenergized.
