1. Measure the battery voltage by holding the meter selector
switch in the BATT V position.
2. If the battery voltage is not the pre-determined float voltage
or the desired battery float voltage, perform the following:
a. If the voltage is too high, turn the OUTPUT VOLTS
ADJ potentiometer counterclockwise on the rectifier
with the highest output current.
b. If the voltage is too low, turn the OUTPUT VOLTS
ADJ potentiometer clockwise on the rectifier with the
lowest output current.
c. Check the battery voltage and repeat Steps a and b
above until the battery voltage is within the required
tolerance of the desired float voltage.
3. If all rectifiers are not carrying some load current (between
5 percent and 95 percent of rated load):
a. Turn Off all spare rectifiers, but leave enough rectifiers
On to handle the load current.
b. Turn up (clockwise) the OUTPUT VOLTS ADJ
potentiometer on rectifiers carrying less than 5 percent
rated load till they carry more than 5 percent rated load,
and
c. Turn down (counterclockwise) the OUTPUT VOLTS
ADJ potentiometer on rectifiers carrying more than 95
percent rated load until they carry less than 95 percent
rated load.
d. Repeat from Step 2 (battery voltage check and
adjustment) until all rectifiers are carrying between 5
and 95 percent rated load and the battery voltage is
within the required tolerance of the desired float
voltage.
e. Turn On one of the spare rectifiers, and turn Off one of
the previously loaded rectifiers (same number of
rectifiers On).
f.
Repeat Steps b through d.
Note
Rectifiers are not required to share load current equally.
