50A SMR
Rectifiers
Use the following procedure to generate an RFA in Lineage Power 50A
SMR Series rectifiers:
Step Action
1 Set the Output CB switch of the rectifier to the Off position.
2 Raise the rectifier voltage (measured via the rectifier voltage
test jacks on the front panel of the rectifier) above the
Backup HVSD level for the rectifier (set via SW100-6/7 on
the front of the rectifier).
3 Verify RFA in the controller.
4 Lower the rectifier voltage once again to plant float and
restart it to retire the RFA.
5 Close the Output CB switch and verify normal rectifier
operation.
Note: Load share should be disabled (BGB SW100-5) anytime that
rectifier voltage is adjusted in these rectifiers with the Output CBs
closed.
If an intelligent controller is being tested, History for all tested alarms
can be reviewed under the front panel path: MAIN
→ HISTORY.
