Samlex America PSE-24275A - Manual (Page 33)

SYMPTOM
The AC output shuts down sometimes
and resumes automatically. Overload
LED is not lighted ( might happen
during starting of certain loads)
The AC output shuts down completely.
The red overload LED is lighted.
Buzzer alarm is sounded. Red Over
Temp LED is on. There is no AC
output
POSSIBLE CAUSE
Temporary shut-down of the AC output
due to instantaneous overload beyond
the surge power rating of the inverter
Permanent shut-down of the AC output
due to continuous overload beyond the
continuous power rating of the inverter.
Note: The unit will be latched in this
shut-down condition. To reset, switch
the power on / off switch to off and then
on again. Before switching on again,
remove the cause of the shut-down
Shut-down due to over temperature
because of fan failure or inadequate
cooling as a result of high ambient
temperature or insufficient air exchange
REMEDY
1. Reduce the load
2. The load is not suitable as it requires
higher power to operate. Use an
inverter with higher power rating
1. Reduce the load
2. The load is not suitable as it requires
higher power to operate. Use an
inverter with higher power rating.
4. If the unit goes into permanent
overload again after resetting and
removing the load completely, the unit
has become defective. Call Technical
support.
1. Check that the fan is working. If not,
the fan / fan control circuit may be
defective. Call Technical Support.
2. If the fan is working, check that the
ventilation slots on the suction side and
the openings on the discharge side of
the fan are not obstructed.
3. If the fan is working and the
openings are not obstructed, check that
enough cool replacement air is
available. Also check that the ambient
air temperature is less than 40º C
4. Reduce the load to reduce the
heating effect.
5. After the cause of over heating is
removed and the unit cools down, it
will reset automatically
