7 - 18 Troubleshooting and Adjustments
Issue 10 July 2000
2. If the rectifier voltage was NOT at the desired float voltage before
it was turned off, rotate the Float Adj potentiometer fully
counterclockwise.
3. At the ac service panel, install the ac fuses or turn the ac input
circuit breaker On.
4. To bring the rectifier into service:
a. Turn the rectifier Power switch On. The green Power LED
must light. Wait 10 seconds.
b. Hold the meter selector switch in the Rect V position, and use a
small screwdriver to turn the Float Adj potentiometer
clockwise until the digital meter reads approximately battery
voltage, typically 52 volts.
c. Turn the circuit breaker CB1 on.
d. Turn the Power switch Off.
5. At the rectifier, connect the control cable connector J5A.
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 per Section 6.
10. If the rectifier is installed in a microprocessor-controlled plant that
has an efficiency algorithm feature, enable this feature. (See the
controller manual for instructions).
Preventive
Maintenance
•
At 12-month intervals, check torque on various connections, such
as ac input and dc output connectors. OBSERVE SAFETY
PRECAUTIONS IF WORKING IN LIVE PLANT. See Tables 8-D
and 8-E.
•
Check calibration of the rectifier’s digital meter.
