OPERATING INSTRUCTIONS: CHARGING
21.
●
SLOW BLINKING RED LIGHT - Indicates possible weak battery.
●
FAST BLINKING RED LIGHT – Before charge this indicates first battery is connected backwards, check connection.
●
CONTINUOUS RED LIGHT - Indicates AC power is on.
●
CONTINUOUS GREEN LIGHT - Indicates correct connection. After battery is connected, if the green light does not light, check for
proper polarity or poor connections. If the battery voltage is below 4 volts the green light will not come on.
●
BLINKING GREEN LIGHT - Indicates charge is complete, charger in the float mode.
●
CONTINUOUS YELLOW LIGHT - Indicates charging, bulk charge, less than 80% charged.
●
BLINKING YELLOW LIGHT -
●
FLASHING GREEN AND YELLOW LIGHTS - Indicates deep discharge recovery process.
NOTES:
FOUR SECOND DELAY
To avoid sparking, the charger tests for correct polarity before applying current to the battery. When connected properly, the green light will
come on for 4 seconds before the yellow light comes on.
DEEP DISCHARGE RECOVERY
If the charger determines a battery is deeply discharged, it will attempt to recover the battery with a program designed to enhance charge
acceptance. Because of the high voltage levels required for recovery, this program is not included for sealed batteries. If charger does not
recover battery then charger will shut off.
OPERATING PROCEDURE
1.
Plug AC cord into outlet. Turn POWER switch OFF.
2.
Select mode of operation Flooded, AGM, or Manual. Most VRLA would be charged with flooded see battery manual for details, if in
doubt charge with sealed.
3.
On the charging rack connect the RED clamps to the positive (+) of the batteries and the BLACK clamp to the negatives (-).
4.
Turn charger to the desired charge rate. General rule 3 batteries or less set to 30A, 4 batteries or more set to 60A. The GREEN light will
come on for 4 seconds. See PREPARING TO CHARGE portion under IMPORTANT SAFETY INSTRUCTIONS of this manual.
5.
The YELLOW light will come on when the GREEN light goes off and charging will begin.
6.
If the battery is deeply discharged, the YELLOW and GREEN lights will flash on and off for up to 30 minutes. In General if the batteries
are below 11V for best results charge battery by itself or on a single charger first. Charging will be discontinued if the battery will not
accept charge after a reasonable amount of time and the RED light will flash. Can also charge on manual mode until the OCV is greater
than 11V, then switch over to automatic charge.
7.
Charging time will depend on the size and state of charge of the battery.
8.
When charging is complete, charger will go into a float mode and the GREEN light will blink.
NOTES ON RECOVERY OF DEEPLY DISCHARGED BATTERIES:
a.
Not all deeply discharged batteries can be recovered.
b.
Most weak batteries will be detected while charging. However, some batteries which have been recovered from a deep discharge will
maintain an acceptable open circuit voltage but have a reduced capacity under load. Always load test or otherwise test a recovered
battery to determine if the CCA capacity is within 80% of the rated value.
PARALLEL CHARGING
22.
Connecting batteries in parallel (see illustration) allows a person to charge a number of batteries at one time using only one 12-volt charger.
The amount of charge being put in the batteries should not exceed the rating of the charger. The amount of charge each battery received will
depend on the state of charge of the batteries on the rack, condition of the batteries, temperature of the batteries, and other factors.
Connecting discharged batteries to a rack of fully charged will not cause the charged batteries to become discharged. With a rack of batteries
in various states of charge, the most discharged battery will receive the largest amount of charge. As it is charged up and becomes equal to
another battery, the two will charge equally and come up together. (See illustration).
