TROUBLESHOOTING
SYMPTOMS WHEN THE CHARGER IS POWERED AND CONNECTED TO
THE BATTERY
THE RED LED IS OFF
The DC side fuse may have blown due to wrong polarity of battery connection. Ensure
positive of the battery is connected to the positive of the charger and the negative of the
battery is connected to the negative of the charger. Check the fuses inside the charger and
replace, if blown.
The battery may be shorted. In this condition, the unit is shut down by the short circuit
protection circuit. Remove the battery connection. If the red LED now comes on, the battery
is shorted. If the red LED still does not come on, check if there is AC power in the receptacle.
If there is power, check the AC side fuse inside the unit. If the fuse is not blown, call
Technical Support.
THE RED LED IS ON BUT THE AMMETER SHOWS NO READING
The battery is fully charged. If the battery is not fully charged, the connection to the battery
may be loose or open. Check tightness and continuity of the battery connection.
THE BATTERY IS GETTING OVER CHARGED OR BOILS
The charger is also feeding other DC load(s) in parallel with the battery. The Dip Switch is not
selected for “Battery with Load“. Change Dip Switch setting to “Battery under Load“
(see under “Powering other DC loads“ on page 10.
SYMPTOMS WHEN THE CHARGER IS POWERED AND DIS-CONNECTED FROM
THE BATTERY
THE RED LED IS OFF
Check there is AC power in the receptacle. If there is power, check the AC side fuse inside
the unit. If the fuse is not blown, check the DC side fuse. If the DC side fuse is not blown,
the output may be shorted. In this condition, the charger is shut down by the short circuit
protection circuit. Check that the output terminals are not shorted. If the terminals are not
shorted , call Technical Support.
AC SIDE FUSE BLOWS AS SOON AS POWER IS TURNED ON
The AC input of charger is 230VAC but the unit is plugged into 115 VAC. Please check
that when operation. If the AC input voltage is correct, the charger is defective.
DC SIDE FUSE BLOWS AS SOON AS THE BATTERY IS CONNECTED
Wrong polarity of the battery connection. Ensure positive of the battery is connected to the
positive of the charger and the negative of the battery is connected to the negative of
the charger.
