4. Set the BATTERY TYPE SELECTOR switch to position “0” or “1”. To start
the equalization charging process, cycle the AC power (i.e., disconnect and
then reconnect the AC source). A solid orange BATTERY CHARGER LED
indicates equalize charge.
a) Position “0” equalizes the batteries at the rate of the battery bank capacity
divided by 40 (C/40) at a voltage of 15 volts for 12-volt systems or
30 volts for 24-volt systems. This is set with the BATTERY CAPACITY
potentiometer.
b) Position “1” equalizes the batteries at the rate set with the BATTERY
CHARGER RATE CONTROL at a voltage of 15.5 volts for 12-volt
systems or 31 volts for 24-volt systems.
When the voltage condition is met and 6 hours have elapsed, the charger will
switch to the float mode. If the condition is not met (i.e., the current draw is
above the rate set with the BATTERY CAPACITY potentiometer (position
“0”) or BATTERY CHARGER RATE potentiometer (position “1”)), the
charger will continue until the condition is met, or for a maximum of
12 hours. At this point the charger switches to float at the equalize 1 or 2
voltage setting (see Figure 3-1, “Battery Type Selector Switch Settings” on
page 3–5).
5. Reset the BATTERY TYPE SELECTOR potentiometer to the appropriate
setting for the system’s batteries when the Equalize charge has completed.
Important:
Recheck the water the level after equalize charging and refill if necessary.
