–
THE AC VOLTAGE IS TOO LOW OR TOO HIGH. CORRECT.
(See the electrical specification table for the allowable AC voltage input ranges. This is an
unusual problem and would most likely occur with a very poorly regulated engine-generator set
providing the AC voltage to the charger)
▶
3 LEDS BLINK THREE TIMES SIMULTANEOUSLY : CHARGER IS OVERHEATED
.
-> NO ACTION REQUIRED. WHEN THE CHARGER COOLS, CHARGING WILL
RE-START AUTOMATICALLY. CHECK AND CORRECT FOR DIRT OR OTHER DEBRIS
ON CHARGER THAT MAY BE REDUCING COOLING.
▶
3 LEDS BLINK FOUR TIMES SIMULTANEOUSLY : INPUT OR OUTPUT
OVER CURRENT.
-> NO ACTION REQUIRED, CHARGER WILL CORRECT AND RE-START
AUTOMATICALLY.
3. 100% LED BLINKS WHILE 50% AND 75% LED'S ARE "OFF"
The 18
hour timer has elapsed or a bad cell in the battery has been detected. Causes:
-> BATTERIES ARE EXTREMELY DISCHARGED. UNPLUG, WAIT 20 SECONDS, AND
THEN PLUG-IN CHARGER TO RE-START CHARGE CYCLE TO COMPLETE
CHARGING.
-> BATTERIES ARE WEAK, OLD, OR HAVE ONE OR MORE BAD CELLS. BATTERIES
WILL STILL CHARGE BUT CAPACITY WILL BE REDUCED. REPLACE BATTERIES.
-> BATTERY PACK TOO LARGE FOR THE CHARGER. USE HIGHER OUTPUT CHARGER OR
UN-PLUG, WAIT 20 SECONDS, THEN PLUG-IN CHARGER TO RE-START CHARGE CYCLE TO
COMPLETE CHARGING.
4. BATTERIES DO NOT FULLY CHARGE
If the batteries are charged overnight, make sure the AC supply is not being switched-off at
night with other building circuits. Check battery condition following the battery supplier’s
instructions. Check for dead cells or reduced capacity. Replace charger only if other problems
are not found.
5. THE AC LINE CIRCUIT BREAKER OR FUSE IS BLOWN
An overloaded AC circuit, defective circuit breaker, defective fuse, or a charger problem can
cause this condition. First check to see what the total load is on the AC circuit to avoid overload.
If total AC load is OK connect the charger to a different AC outlet (on a different circuit) in the
building. If the charger operates properly on other AC outlets, a qualified person should correct
the AC circuit problem. If the AC supply checks good, the charger should be replaced.
Note: Over 1/2 of all battery chargers returned as "failed" are good. Please follow the
troubleshooting procedures carefully and check all other items before returning the
charger as failed.
