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.
• 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.
CHARGING Indicates that the battery charger is charging the batteries:
• If the LED is not on, the batteries may be fully charged and the charger is supplying a
oat voltage to the batteries to keep them fully charged.
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.
Dry Contact Relay
To use your dry contact output fail relay you must connect a 9-pin D connector to the unit.
You must use pins one and six as is indicated on page 9 in the remote connector diagram.
The relay is factory preset to fail in the closed position when the low output LED and buzzer
come on. If you wish to have the relay fail in the open position when the low output LED and
buzzer come on, you must take the cover off the unit and move the jumper to the other posi-
tion on J22. J22 is located next to the relay.
