TROUBLESHOOTING
PROBLEM: No LED indicators illuminated on battery status indicator.
Solution Sequence:
1. Confirm that current is being delivered to the charger. Use a meter or test light to check the AC power supply from its source
through all connecting points up to the charger.
2. Check that the AC circuit breaker (on front of the unit) is depressed.
3. Call technical support for further assistance (800.742.2740).
PROBLEM: The charge status indicator changes rapidly back and forth from red to green or the green LED will not
illuminate after excessive charging time (24 hours or more).
Solution Sequence:
1. Disconnect AC power from the charging system. This indication may signify a possible battery problem.
2. Call technical support for further assistance (800.742.2740).
PROBLEM: A green LED was illuminated before disconnecting the power from the charger, but upon reconnection,
red LEDs appear and remain on.
This is the normal operating procedure for the system. It indicates that a reanalysis of the battery status was initiated and after a
series of steps the green LED will illuminate.
LIGHT EMITTING DIODES (LED) FAULT CODE INDICATIONS
The microprocessor is constantly monitoring the charger circuitry and will both detect and display blinking LED indications if a
fault is detected. The battery type LED will be
OFF
during a fault code condition.
30 & 60% RED LEDS BLINKING ………………..…..…FORMING STAGE TIMEOUT SHUTDOWN
This indication occurs if the battery voltage has not risen above 1.75 volts per cell within the first 3 hours of charging. This indicates that a possible battery
problem exists and that the charge cycle has been terminated at this point.
30, 60 & 90% RED LEDS BLINKING............................................OVERALL TIMER SHUTDOWN
This indication occurs if the charger has not completed the charge cycle within the allowable factory set time period. This indicates that a possible battery
problem exists and that the charge cycle has been terminated at this point.
30 & 90% RED LEDS BLINKING …..…..............................INTERNAL OVERTEMP SHUTDOWN
This indication occurs if the charger circuitry has detected operating temperatures inside the charger enclosure that are above factory specified levels. This
could indicate that a possible charger problem exists and that the charge cycle has been terminated.
30% RED & 100% GREEN LEDS BLINKING …..….......................... BULK DV/DT STAGE SHUTDOWN
This indication occurs if the battery voltage does not rise properly during the Bulk Stage. This indicates that a possible battery problem exists and that the charge
cycle has been terminated at this point. Please call technical support for further assistance (800.742.2740).
30% RED & 100% GREEN LEDS ALTERNATE BLINKING ON OFF…..….................. NO BATTERY DETECTED
This will be the NORMAL indication when the charger is plugged into A/C but not connected to a battery pack. Please call technical support for further assistance
(800.742.2740).
Note: Disconnecting and reconnecting the AC power supply cord will reset the charger.
