3. Turn the rectifier off and repeat this procedure for each
rectifier in the group.
4. Turn all rectifiers on after the last rectifier is adjusted.
Adjust Rectifiers
as a Group
If the load requirement is always greater than the capacity of
the smallest rectifier, adjust the rectifiers to float voltage using
the following procedure. Rectifiers must be on line with plant
cables connected and REG fuses installed in the plant controller
or a remote bay.
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.
c. Turn down (counterclockwise) the Output Volts Adj
potentiometer on rectifiers carrying more than 95
Note
Rectifiers are not required to share load current equally.
