7 - 12 Troubleshooting and Adjustments
Issue 4 May 1998
b.
Hold the meter selector switch in the RECT V
position, and use a small screwdriver to turn the
OUTPUT VOLTS ADJ potentiometer clockwise
until the digital meter reads approximately battery
voltage, typically 26 volts for 24-volt plants or 52
volts for 48-volt plants.
c.
Turn the DC OUTPUT circuit breaker On (up).
d.
Turn the POWER switch Off.
5. At the rectifier, connect the control cable connector J2A.
6. At the plant controller, install the REG fuse associated
with the rectifier that is being restored to service.
7. Turn the rectifier POWER switch On.
8. Close the rectifier front door and secure the locking
screws.
9. Adjust the rectifier to float voltage. (See Section 6,
“Adjusting Rectifiers to Float Voltage.”)
10. If the rectifier is installed in a microprocessor-controlled
plant that has an efficiency algorithm feature, enable this
feature. (See the controller product manual for
instructions).
Notes
If the rectifier continues to operate, proceed to Step b.
If the rectifier shuts down due to initial high voltage, monitor
the RECT V voltage. When this reading reaches 26 volts for
24-volt plants, or 52 volts for 48-volt plants, turn On the
circuit breaker.
If the rectifier shuts down for any other reason, such as
component failure, see Table 7-A.
