HB600-24B CHARGER MANUAL 06JAN2009
- 10 –
▶
3 LEDS BLINK TWICE SIMULTANEOUSLY : AC VOLTAGE PROBLEM.
-> CHECK THE AC INPUT VOLTAGE. THE CHARGER IS INDICATING
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 : 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 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.
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 items.
- If batteries are new they sometimes need 20 to 30 charge/discharge cycles before they
charge normally. With new batteries the charger LEDs may only show 50% on, 75% on, and
100% flashing after overnight charging. The batteries and charger are fine – the machine
should be used and charged overnight. Within a few weeks all three LEDs will go steady on at
the end of charge.
- If batteries are old check the battery condition following the battery supplier’s instructions.
Check for dead cells or reduced capacity. Replace charger only if other problems are not
found. If the charger LEDs are showing charging progress and charger case gets warm after
several hours the charger is probably good and the batteries bad.
- If the 50% and 75% LEDs are “off” and the 100% LED is blinking after a long charge time, the
batteries have not fully charged after 18 hours of charging time. If this occurs with new
batteries the machine should be used normally and the problem should go away after several
weeks of use. If the batteries are old they may be bad and should be checked.
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 the total load 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
