Troubleshooting
This unit provides LED indicators and a buzzer to help diagnose any problems. The unit should
sound the buzzer to alert you prior to shutting itself down. You should immediately check the
indicators to determine the cause of the shutdown.
LOW OUTPUT Indicates that the output voltage is below normal because:
• The current demanded by the devices connected to the unit exceeds the maximum
output current rating, causing the output voltage to drop to maintain the current at
the maximum level,
• The input voltage is not high enough for unit to operate,
LOW INPUT Indicates that the input voltage is below normal because:
• The input voltage is not in the correct range for proper operation of the unit.
OVERTEMP Indicates that the Battery Charger is running too hot because:
• Too much power is being drawn, turn off or unplug some devices.
• The Battery Charger is located in a poorly ventilated area.
OVERLOAD Indicates that the load it trying to draw to much current because:
• Too much power is being drawn, turn off or unplug some devices.
If the load exceeds the continuous rating for too long a period, the temperature sensor inside
the unit will turn off the outputs. After the unit cools sufciently, it will automatically come
back on. If this happens frequently, remount the unit for increased airow so it cools better.
