Battery Charger (Moran
®
)
DESCRIPTION
Some early model lift trucks are equipped with a
Moran
®
battery charger which can be identified by its
LED configuration. See Figure 22. This charger is a
self contained 120 volt AC powered charger. The
charger comes equipped with a short lead plug to al-
low connection to the 120 volt AC outlet using a 20
amp rated extension cord. The charger will operate
from any wall outlet capable of supplying 108 to 126
volts AC protected by a 20 amp circuit breaker.

OPERATION
Charging
Pressing the ON button at the top of the charger
starts the charging cycle. A yellow LED will illuminate
to indicate that charging has begun. Battery charging
is automatic once the charging cycle has started. The
green LED will illuminate once the charging cycle has
been completed. Refer to Figure 22.
Equalize
The charger will automatically begin a equalizing cy-
cle to equalize the charge of the batteries immediately
after the batteries have been fully charged. The
charger is equalizing when the yellow LED is flashing.
Signals
The battery charger comes with a red LED that will il-
luminate or flash if a malfunction of the charger or bat-
tery occurs.
One of the following may be the cause in the event of
charger failure and the red LED is blinking:
• AC mains failure
• DC fuse blown
• Power circuit break down
One of the following may be the cause in the event of
battery failure and the red LED is ON:
• The total security time, 14 or 15 hours, has ex-
pired.
• The security time before the battery gassing
voltage, 10 hours, has expired.
• The battery voltage is lower than 2.05V per cell
after one hour of charge.
Protections
The following describes the protections of the battery
charger:
• A fuse protects the DC circuit in the event of
prolonged over-current or possible polarity in-
version.
• An automatic device allows the charge to begin
only after five minutes from the connection to
the battery.
• In case of mains failure, the charge is cut off
temporarily, the red LED blinks. The charge
continues when the mains is restored.
TROUBLESHOOTING
NOTE: If all the below steps have been taken and
the charger still does not function properly, the
charger should be replaced.
If the charger will not power up, proceed with the fol-
lowing:
• Check AC wall outlet for power. Acceptable
power range at the outlet should be between
108 and 126 volts on a 20 amp circuit.
• Check for blown AC input fuse, that is located
on the charger bottom. See Figure 23.
