TROUBLESHOOTING -GENERAL
PROBLEM : Power ON/OFF switch does not illuminate when turned on.
PROBABLE CAUSE SUGGESTED REMEDY
No power in the AC outle t Check there is power in the outlet.
AC side fuse inside the power Replace the fuse inside the unit.
supply is blown See fuse ratings at page 8
PROBLEM : AC side fuse blows as soon as power is turned on.
PROBABLE CAUSE SUGGESTED REMEDY
Unit is defectiv e Please contact your dealer
PROBLEM : The output voltage is 0 V or very low
PROBABLE CAUSE SUGGESTED REMEDY
Input voltage is very lo w Check that the input voltage is V
The unit is in current limit condition Check the output terminals are not
due to overload caused by large reactive shorted. Remove the load. If the output
loading or by the output being voltage gets restored, the load is shorted
short circuited or is offering large reactive impedance.
Unit is shut down due to over Check that the fan has not failed or
temp. (SEC-1225G/1235 /2412G) the vent openings are not blocked
PROBLEM : Output voltage drops as soon as the load is switched on
PROBABLE CAUSE SUGGESTED REMEDY
The unit is going into curren t Reduce the load current to less than
limit protection mod e the current limit value. Motors,
pumps, compressors,zrelays, incan-
descent and halogen lamps and large
capacitors in the input section of the
DC devices draw very high inrush or
starting currents of up to 10 times
their normal operating currents.
Ensure that these inrush/starting
currents are below the current limit
value of the power supply.
