Description
Nominal Boost Voltage
V
6.0
60.0
28.8
This is the max charging voltage
allowed during the boost cycle.
Stop Current Percent
%
0
90
0
If this value is different from zero, when
the charge current falls below this
percentage of the max charge current,
then the charge cycle will be supposed
to be terminated.
If this parameter is set to zero, the
controller will monitor the charge current
automatically. When the charge current
is stabilized in a 5 minute interval, it will
conclude that the charge cycle is
terminated.
Idle Speed RPM
rpm
0
4000
900
This is the engine speed in IDLE
SPEED mode. This speed is maintained
with PID control.
RPM High Limit
rpm
750
8000
2000
This is the maximum allowed rpm of the
engine during charge cycle. If the
engine speed approaches this limit, the
controller will stop increasing the
current.
Battery Bank Over
Current
A
1
2000
63
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.
Battery Bank Over Load
kw
0.1
200.0
1.6
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.
Alarm Warning Timer
sec
0
10
1
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
engine rpm goes out of the limits and
OVERSPEED or UNDERSPEED alarms
occur.
This is also the period between the
alternator voltage goes out of the limits
and HIGH VOLTAGE or LOW
VOLTAGE alarms occur.
Genset Low Voltage
Shutdown Limit
V
0.0
460.0
9.0
If the battery bank DC voltage goes
under this limit, this will generate a
GENSET LOW VOLTAGE shutdown.
Genset High Voltage
Warning Limit
V
0.0
460.0
63.0
If the battery bank DC voltage goes
above this limit, this will generate a
GENSET HIGH VOLTAGE warning.
Genset High Voltage
Shutdown Limit
V
0.0
460.0
66.0
If the battery bank DC voltage goes
under this limit, this will generate a
GENSET HIGH VOLTAGE alarm and
the engine will stop.
