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.
SYMPTOMS
CAUSE
Overload LED is glowing The current demanded by the load has exceeded the maximum
output rating for too long of a time.
FIX:
Check that the connection to the load is intact and not
corroded. Reduce the number of devices connected to the
voltage converter.
The Overtemp LED is
glowing
The voltage converter is running too hot.
FIX:
Check that the load is suitable for the output. The converter
may heat up if it is running at its maximum output for too long
of a time. Remount the unit for better airflow and ventilation.
Input fuses blown when
unit is turned ON
The power source may be connected to the unit with the
wrong polarity.
FIX:
Reverse the polarity of the power source connection so it is
properly connected. If the polarity is already correct, then
the unit is damaged and must be returned for repair.
The Low Input LED is
glowing
The unit is not receiving enough power to operate normally.
FIX:
Check that the connection to the power source is intact
and not corroded. Check that the power source is properly
rated for use with the voltage converter. If there are no
power source issues, then the unit is damaged and must be
returned for repair.
The Low Output LED is
glowing. Overload LED may
be glowing
The unit’s output voltage has fallen below the range needed for
normal operation
FIX:
The current demanded by the load may be causing the output voltage
to drop to maintain the current at the maximum level.
