Group Parameter Definition
Unit Min Max Description
6
610
High Bat Voltage
Shutdown
V 12.0 33.0 If the battery voltage goes over this limit,
this will generate a
High Battery Voltage
Alarm
and shut down the engine
immediately.
6
611
High Bat Voltage
Warning
V 12.0 33.0 If the battery voltage goes over this limit,
this will generate a
High Battery Voltage
Warning
.
6
612
Low Bat Voltage
Warning
V
0
28.0 If the battery voltage falls below this limit,
this will generate a
Low Battery Voltage
Warning
.
6
613
Low rpm Shutdown
Rpm 0 6000 If engine speed measured from the
magnetic pickup input falls below this limit,
this will generate a
Low rpm Alarm
and
shut down the engine immediately.
6
614
Low rpm Warning
Rpm 0 6000 If engine speed measured from the
magnetic pickup input falls below this limit,
this will generate a
Low rpm Warning
.
6
615
High rpm Shutdown Rpm 0 6000 If engine speed measured from the
magnetic pickup input goes over this limit,
this will generate a
High rpm Alarm
and
shut down the engine immediately.
6
616
High rpm Warning
Rpm 0 6000 If engine speed measured from the
magnetic pickup input goes over this limit,
this will generate a
High rpm Warning
.
6
617
Excess Power Load
dump
KW
0 2500 If the genset load goes over this limit, this
will generate a
Excess Power Load Dump
Alarm
and shut down the engine after
cooling period.
6
618
Reverse Power Load
dump
KW
0 2500 If the genset is consuming more power
from the mains than this limit, this will
generate a
Reverse Power Load Dump
Alarm
and shut down the engine after
cooling period.
6
619
Crank Teeth Count /
Multiplier Coefficient
-
0
250
P_626=0 :
This is the number of pulses
received from the magnetic pickup input for
one turn of engine crank. This parameter is
used for the calculation of the engine rpm.
If this parameter is set to ‘0’ then the
magnetic pickup input is not used.
P_626=1 :
This is the
multiplier
coefficient
of the alternator when the
engine RPM is computed from the genset
frequency.
6
620
Hysteresis Voltage
V
0
30 This parameter provides the mains and
genset voltage limits with a hysteresis
feature in order to prevent faulty decisions.
For example, when the mains are present,
the mains voltage low limit will be used as
the programmed low limit
P_512
. When the
mains fails, the low limit will be used as
P_512+P_620
. It is advised to set this
value to 10 volts.
