Description
(2) Reverse power warning
limit
KW 0
If the genset power is negative and goes above this
limit then a REVERSE POWER warning will be
generated.
( 2 ) Reverse power
loaddumpg limit
KW 0 If the genset power is negative and goes above this
limit then a REVERSE POWER loaddump will be
generated.
(2) Load Shedding Low
Limit KW 0
If the genset power goes below this limit then the load
shedding relay will be deactivated.
(2) Load Shedding High
Limit KW 0
If the genset power goes above this limit then the load
shedding relay will be activated.
(2) 2
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.
(1) 2
nd
Mains Voltage Low
Limit
V 84
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 136
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) 2
nd
Mains Frequency
Low Limit
Hz 55
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) 2
nd
Mains Frequency
High Limit
Hz 65
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.
(2) 2
nd
Genset Low Voltage
Shutdown Limit
V 90
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 94
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 130
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 136
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.
