d) After 30 ± 3 minutes of topping time the green READY LED will light and the
yellow CHARGING light will extinguish. Note the elapsed time. The indicated
voltage will drop towards 25.2 Volts over a few seconds (time set by the
capacitor and resistor choice).
e) As the indicated voltage drops below 25.2 Volts, the yellow CHARGING LED will
again light and the green READY LED will extinguish. Immediately begin timing
the second topping duration.
f) After 15 ± 1.5 minutes the second topping charge will complete, the green
READY light will illuminate, and the yellow CHARGING LED will extinguish.
Note the elapsed time. Again, the indicated voltage will drop towards 25.2 Volts.
g) As the indicated voltage drops below 25.2 Volts, the yellow CHARGING LED will
again light and the green READY LED will extinguish. Immediately begin timing
the third topping duration.
h) After 2 minutes ± 15 seconds the third topping charge will time out, the green
READY light will light and the yellow CHARGING light will extinguish. Note the
elapsed time.
i) The Activator 282 will repeat this cycle with two minute topping charges
indefinitely, until AC power is removed.
7.0 ROUTINE MAINTENANCE
There are only three items that require routine maintenance:
a) Fan – Keep clean and free of dust or debris. Use low pressure air or vacuum
cleaner. Check air vent holes. Vacuum clean if necessary.
b) Connections – Check that the quick disconnect contacts are tight and free of
corrosion. Use approved contact cleaner. Check movement of the quick –
disconnect knob – clean and lubricate if necessary. Do not get lubricate on
the contacts or inside the unit.
