K43D01-EN - 37 -
The unit decides with precision the moment to run the genset and performs a high efficiency charging cycle.
The complete charging cycle will always include a float charge cycle. Following programming, a boost charging
cycle may be added.
The maximum charge duration is limited with parameter “
Max Charge Time
”. Following the value of the
parameter “
Stop Current percent
”, the controller will detect precisely the end-of-charge condition and will
stop the engine before the expiration of the Max Charge Time parameter, providing fuel economy and longer
service life.
(1)
Start to Charge Voltage
V
24.0
When the battery bank voltage falls below this level,
then the controller will initiate an automatic charging
cycle. The default value is set for a 24V battery
bank.
(1)
Max Charge Current
A
50
This is the maximum allowed charge current flowing
from the alternator to the battery bank.
(1)
Max Charge Time
min
120
This is the maximum duration of a charge cycle.
Even if the charge cycle is not completed at the
expiration of this timer, the engine will stop.
(1)
Nominal Charge Volt
V
27.4
This is the float charge voltage of the battery bank.
The default value is set for a 24V battery bank.
(1)
Max Battery Temperature
°C
90
This is the maximum allowed temperature of the
battery bank. If the temperature approaches this
limit, then the charging current will be reduced.
(1)
Boost Enable
-
0
0
: No boost charge cycle
1
: Boost charge cycle is performed. The charge
voltage will be set to the nominal boost voltage
during boost execution time.
(3)
Boost Start Current
%
30
If the boost charge is enabled, when the charge
current goes below this percentage of the max
charge current, then the boost charge cycle will be
initiated.
(1)
Boost Execution Time
min
3
If enabled, the boost charge is performed during
this timer.
(1)
Nominal Boost Voltage
V
28.8
This is the max charging voltage allowed during the
boost cycle.
11.1. RELATED PARAMETERS
It is strongly recommended to wire speed detection
through MPU, charge alternator pulses or J1939-
CANBUS and enter correct low and high rpm limit
values in order to preserve engine speed protection.
