Testing the Charging Cycle
Before starting this procedure:
• Confirm that the battery voltage
is above 1.7 x Number of Cells
(36 volts = 18 cells = 1.7 x 18 =
30.6 volts). If the battery voltage
is low, the charger may have to be
started manually by pressing the
Low Voltage start switch.
• Confirm that the AC outlet used is
functioning properly.
Connect a volt meter to the batteries to monitor charging voltage
during procedure.
The charging cycle has multiple stages depending on the
battery profile selected.
Flooded Lead Acid battery profile (FLA, Wet):
Stage 1: Constant Current (start)
Stage 2: Voltage Slope
Stage 3: Constant Current (finish)
Sealed battery profile (AGM, SLA):
Stage 1: Constant Current
Stage 2: Constant Voltage
Note: Each stage has a maximum time interval. If the
maximum time interval is reached in any stage,
then the charge cycle is terminated and a fault is
registered.
1. Connect the charger to the AC power source.
2. The charger should automatically start as indicated by the
flashing Status LED.
• If the charger does not start, try pressing the Low
Voltage Start switch for 10 seconds.
• If the charger still does not start:
> Check the AC and DC wiring to the charger.
> Check the charger fuse. Note: A blown fuse
is typically due to faulty charger components
or reversed polarity charger DC wiring.
> Check the internal charger components.
3.
Constant Current Mode:
The starting current should be
close to the value in the table but may drop soon after
starting depending on the discharge level of the battery.
4. If the battery voltage does not reach the Minimum Voltage
in the Minimum Voltage Time, then the charge cycle is
terminated and a fault is registered.
5. The battery voltage will rise until the Knee #1 Plateau
voltage is achieved (see table) then switch to the next
stage.
The following stages will depend on the type of charging profile
selected:
AGM Profile
6.
Constant Voltage Mode:
The battery voltage is held at
Knee #2 Plateau voltage. Once in this stage, the charger
monitors the charging current and terminates the charge
cycle when the current remains constant for a preset time
period. This is called DI/DT which means the Change in
Current over the Change in Time.
FLA Profile
6.
Voltage Slope Mode:
The voltage is allowed to rise slowly
as the current is decreased until the Knee #2 Plateau
voltage is achieved. It holds this voltage until the current
has decreased to the Finish Current value then switches
to the next stage.
7.
Constant Current Mode (finish):
The current is held at
the Finish Current value. Once in this stage, the charger
monitors the charging current and terminates the charge
cycle when the battery voltage remains constant for a
preset time period. This is called DV/DT which means the
Change in Voltage over the Change in Time.
