BATTERY SYSTEM
See the following chart as to what the light mean.
IMPORTANT NOTE! DO NOT unplug any charger’s DC plug from the machine while the
charger is running. This can cause an electrical arc that can ignite any flammable gasses
that are in the area from either the batteries being charged or other environmental sources.
There is also the possibility of damaging the charger should it be unplugged from the DC
current side while charging.
FAULT CODES
FLASHING RED LED: Corrupt program memory in micro controller detected, charger mi-
croprocessor has become corrupted. Charger must be returned to the factory.
FLASHING YELLOW LED: Timer has expired. The 253-2441 uses a timer to independent-
ly monitor each mode of the charge cycle: bulk, absorption and finish. If the timer expires
during any of these modes of the charge cycle, there could be a problem with the battery
set. The timer may expire if there is a damaged battery cell in the battery set, an abnor-
mally high ambient temperature at the charger or some other external fault, which prevents
completion of charge cycle. These problems need to be addressed by user intervention.
Charger must be AC powered down and disconnected from the battery in order to reset
fault condition. Before resetting the charger investigate potential problems with battery or
other external faults. Once external problem is resolved, reconnect charger output cable
and reconnect AC power
MAINTENANCE
Periodically clean both battery terminals with baking soda and tighten all connections. No
other maintenance on the charger is required.
