TROUBLESHOOTING

The symptoms of abnormal operation and the possible cause(s) and remedies are 

given in the succeeding paragraphs

There is no output. The AC power on / off switch (9) does not illuminate when

switched on. The charging indicator LED (4) is off (On the Remote Panel (15), 

the Green LED under “Power” is off).

a) There is no AC input voltage in the outlet: Check that AC power is available in

the AC outlet receptacle and that it is switched on.

b) The AC input side fuse is blown due to:

• High input voltage - Check that the input voltage is 230 VAC nominal (normal

range is 207 to 253 VAC).

• High voltage transients / surges in the AC input line – Ensure that the AC input

voltage is clean and does not have high voltage transients / surges. Input voltage

surges / transients > 340 VAC (for 230 VAC input) will blow the AC side fuse.

Use a suitable AC line conditioner / surgesuppressor, if necessary.

• The unit has become defective – If fuse is not blowing due to the above two causes,

the unit has become defective.

There is no output voltage and the Charging Indicator LED (4) is red (On the Remote

Panel (15), the Red LED under “I Phase” is lighted, the Green LED under “Power” 

is lighted).

a) The DC side output fuse is blown. The DC side fuse will blow if the battery is connected

in wrong polarity. Ensure that the Positive battery post is connected to the Positive

connector of the charger (either Bank 1 or Bank 2) and the Negative battery

post is connected to the Negative connector (common) of the charger. Replace the fuse

with the fuse with the properrating.

b) The battery / DC load is shorted. Check and remove the short circuit. The charger will

latch in the off condition if it was shut down due to short circuit and will 

NOT re-set

automatically

. To re-set, switch off the AC power input on / off switch (9) and switch

on again.

c) Shut down due to high temperature. Check that the cooling fan is working, the air vents 

are not clogged and the ambient temperature is not very high. The charger will be latched 

in this shut down condition and will 

NOT reset automatically

  even after the unit has

cooled  down. To reset, the AC input power on / off (9) switch has to be switched off and 

on again.
