TROUBLESHOOTING - GENERAL 
 
PROBLEM : Power ON/OFF switch does not illuminate when turned on. 
 
PROBABLE CAUSE 
SUGGESTED
REMEDY
 
 
No power in the AC outlet 
Check there is power in the outlet.
AC side fuse inside the power
Replace the fuse inside the unit. See
supply is blown
fuse ratings at page 8
PROBLEM : AC side fuse blows as soon as power is turned on.
PROBABLE CAUSE
SUGGESTED
REMEDY
 
 
Unit is defective 
Call technical support.
 
PROBLEM : The output voltage is 0 V or very low 
 
PROBABLE CAUSE 
SUGGESTED
REMEDY
 
Input voltage is very low 
Check that the input voltage is 230 VAC
 
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-1223CE)
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 current 
limit protection mode

Reduce the load current to less than 
the current limit value. Motors, 
pumps, compressors, relays, 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. En-
sure that these inrush/starting cur-
rents are below the current limit value 
of the power supply.
