OPERATING INSTRUCTIONS: CHARGING
●
SLOW BLINKING RED LIGHT
- Indicates possible weak battery.
●
FAST BLINKING RED LIGHT
– Before charge this indicates battery is connected backwards, check connection.
●
CONTINUOUS RED LIGHT
- Indicates AC power is on.
●
RED FLASH OFF EVERY 5 SEC
– Charger believes connected to 24V battery.
●
CONTINUOUS GREEN LIGHT
- Indicates correct connection. If when battery is connected, 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 -
Indicates finish charge, greater than 80% charged.
●
FLASHING GREEN AND YELLOW LIGHTS
- Flooded batteries only. 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.
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. Select Battery size 12V or 24V.
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 section 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). If 24V charge on 12V first and then switch to 24V.
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
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). Select Battery size 12 or 24V.
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.
