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.
OPERATING PROCEDURE:
1.
Plug AC cord into outlet. Turn POWER switch ON. RED light will come on.
2.
Select mode of operation Flooded or Sealed/GEL. Most VRLA would be charged with flooded see battery manual for details, if in doubt charge with sealed.
3.
Connect the RED clamp to the positive (+) and the BLACK clamp to the negative (-). The GREEN light will come on for 4 seconds. See PREPARING TO
CHARGE portion under IMPORTANT SAFETY INSTRUCTIONS of this manual.
4.
The YELLOW light will come on when the GREEN light goes off and charging will begin.
5.
If the battery is deeply discharged, the YELLOW and GREEN lights will flash on and off for up to 30 minutes, in flooded setting.
6.
Charging will be discontinued if the battery will not accept charge after a reasonable amount of time and the RED light will flash.
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.
DEAD BATTERY OVERRIDE
If the battery voltage is below 4V the battery charger will not recognize that it has been connected to a battery. Most batteries even if completely discharged will
recover to a voltage greater than 4V, but if a battery is left in a discharged state for an extended period of time the voltage may fall below 4V. This charger has
been equipped with a Dead Battery Override switch; this can be used to start the charger if the battery voltage is below 4V.
OPERATION:
a.
Connect the deeply discharged battery to charger, battery should be placed as far away from the charger as the cables will allow. (See Section 18). Please
insure that the battery is connected with the correct polarity.
b.
Press and hold the override switch; green LED should light, if monitoring the battery voltage should see it rise.
CAUTION: Never press the override switch without a battery connected.
c.
After several seconds release the override switch, if the battery will accept a charge it should now start charging. For best results the Battery Type switch
should be set for flooded. If the battery is a sealed type; the Battery Type switch can be changed after the battery has reached the gassing point (Yellow Led
starts to flash).
d.
The battery may have to be connected to the charger several times before the charger will not fail the battery as a bad battery (Red Led Flashing). NOTE:
The operator should only need to press the override for the first attempt to recover the battery.
. OPERATING INSTRUCTIONS: ELECTRICAL STABILITY SYSTEM
22
General operation:
1.
With AC cord plugged into an outlet the RED light will be on continuously.
2.
For best results the battery should be fully charged before being used with the Electrical Stability System
3.
Set the selector switch to the ESS/FLASH setting (center).
4.
Connect the RED clamp to the battery positive (+), connect the black clamp to the grounded frame of the vehicle (see Sec-17 on charging batteries installed
in a vehicle), in the unusual case that the vehicle has a positive ground, connect the black clamp to the battery negative post (-) and the red clamp to the
chassis.
5.
When the charger detects the battery voltage is present the GREEN light will light for 4 seconds. The YELLOW light will then come on and the unit will
start to ramp up the DC current. When the charger reaches the safe operating level the YELLOW light will start to blink.
6.
The unit will not shut off, it will maintain the voltage within it's capabilities until the unit is turned off.
7.
If the voltage should fall below the specified level the YELLOW light will return to continuously on. If the unit can not maintain the voltage level for more
than 20 seconds then the RED light will start to flash. At this point the unit is supplying maximum output and the battery voltage should be monitored to
make sure it does not drop below minimum levels required for testing and/or programming.
