6) (Optional, for use with power resistor) Wire, #22AWG (0.65mm), 6 ft (2 meters)
7) (Optional, for use with power resistor) Wire, #18 AWG (1mm), 6 ft (2 meters)
Procedure:
1) (Optional) Into each tip plug connect 3 feet of #18AWG and #22AWG wire. The
#22 will go to a voltmeter and the #18 will sometimes be connected to the power
resistor.
2) Connect the Activator 282 to a Lead Acid battery and set the front panel switch to
“Lead Acid”.
3) Connect a voltmeter to the red and black tip jacks on the Activator 282, either
directly or through the added #22 wires.
4) Turn on the Activator 282 to charge the battery. Leave the Activator 282
charging the battery for at least three charge cycles, so that the Activator 282
“topping charge” is only two minutes.
5) Observe the voltmeter as the battery approaches 28 Volts with the Activator 282
yellow CHARGING LED lit. When the green READY LED comes on, note the
highest voltmeter voltage. That must be 28.2V within ± 0.3 Volts. If not, the
Activator 282 must be returned to the factory for repair and calibration.
NOTE – the topping charge will slowly raise the battery voltage above the
internal charge voltage threshold. Using a two minute topping charge
minimizes this error. Using a good battery minimizes this error.
6) (Optional, for use with power resistor) With the voltmeter still connected and the
Activator 282 showing the green READY light, apply the power resistor across
the two tip jacks through the #18 wire harness constructed above. This will
discharge the battery, since the Activator 282 has cut off charging when the
READY light is illuminated.
7) Observe the voltmeter as the battery voltage approaches 25.2 Volts with the
Activator 282 green READY light illuminated. When the yellow CHARGING light
comes on, note the lowest voltmeter reading. That must be 25.2W within ± 0.3
Volts. If not, return the Activator 282 to the factory for repair and calibration.
