Serial Interface Rectifiers
1. Turn the rectifier Off. Wait for the rectifier to power down.
2. Insert a plastic stick between the front panel grills to block the fan
rotation.
3. Turn the rectifier On. After several seconds, the rectifier will issue
an RFA alarm and the plant will generate a PMN.
4. Remove the fan obstruction and toggle the power switch off and
back on to restart the rectifier and retire the alarm.
Parallel Interface Rectifiers
Generate a RFA (Rectifier Fail Alarm) in each of the plant rectifiers
individually and verify that the RECT and MINOR LEDs become active
along with the Power Minor and RFA alarm relays.
For Tyco Electronics J855-series or J874-series rectifiers an RFA is
easily accomplished by operating the “+V” or “-V” fuse alarm circuit by
inserting a paper clip into the alarm indicating hole of the fuse holder.
For Tyco Electronics J85702E-series (150A SMR) rectifiers an RFA
may be generated by setting the rectifier to t he Single PMA Fail option
(by placing BGB1 SW100-8 to OPEN), setting the Output CB switch of
all three PMAs inside the rectifier to the OFF position and then raising
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 SW 100-6/7 on the BGB1 display/control card of the
rectifier). After the RFA has been verified in Galaxy SC, lower the
rectifier voltage once again to plant float and restart it to retire the RFA.
Close the PMA Output CB switch of all three PMAs and verify normal
rectifier operation. Note: Load share should be disabled (BGB1
SW100-5) anytime that rectifier voltage is adjusted in these rectifiers
with the PMA Output CBs closed.
In a similar manner, for Tyco Electronics 50A SMR-series rectifiers, a
RFA may be generated by setting the Output CB switch of the rectifier
to the OFF position and then raising 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). After the RFA has been verified in Galaxy SC, lower the
rectifier voltage once again to plant float and restart it to retire the RFA.
Close the Output CB switch and verify normal rectifier operation. Note:
