The green LED is illuminated whenever the charge cycle is complete and the internal circuitry has determined the batteries to
be fully charged. After the completion of the charge cycle, the green LED will remain on.
Your system provides an auto reset stage every 30 days if left plugged in to AC. In addition, for Li Only setting, unit
will reset every 48 hours in to replace any battery capacity lost due to internal cell balancing. Note: During this
process the LEDs will go through their normal routine (Red LEDs counting up for % of charge along with the
illuminated Amber LED Battery Type) until the unit returns to the maintenance mode and a steady Green LED and
steady Amber Battery Type LED.
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 (
615.471.5300
).
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 (
615.471.5300
).
PROBLEM: A green LED was illuminated before disconnecting the power from the charger, but upon reconnection,
red LEDs appear and remain on.
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.
When first connected to DC (AC not connected), the LEDs will display one or more of the following:
1.
The LEDs will flash the charger’s ID code (this is for PCS internal use only). Once the LEDs flash the ID, they will only display one
yellow LED. This configuration will remain until AC is detected and a charge cycle is in progress.
2.
There is also a possibility the LEDs will not flash their ID code and only show a yellow LED.
3.
Lastly, the LEDs may not flash their ID code and may not show any LEDs until AC is detected.
If the AC line and neutral wires are reversed, the unit will wait 2 minutes before starting a charge. NOTE: The 2 minute wait period will also be a
factor if the charger is being powered by anything other than normal grid AC such as a conventional generator, inverter, etc.
If AC is disconnected while charging, the unit will turn off as expected. The user may hear some clicking noise, but should not be alarmed. This is
the Powered by Battery/DOE functionality checking for AC connection.
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.
