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% RED LED BLINKING ..................................................................NO BATTERY DETECTED
This indication occurs whenever the charger circuitry cannot detect a battery. The charger circuitry will not allow charge
current to flow under this condition. With the AC power supply cord unplugged, check the connection to the batteries for
proper polarity (black wire to negative or -). Also check for corrosion free secure connections to the battery.
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 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
