AC Power Query Test (#78)
1. For a nominal holdover system, if there is no AC power at the
wall outlet, have a qualified electrician restore power to the
outlet. Power should range from 170 to 264 VAC.
2. If there is AC power at the wall outlet, there could be a problem
with the RM0850 rectifiers, BU3200A BIU (battery interface
unit), or battery. Resolve every alarm logged against POWER,
and rerun the test.
3. If the test still fails, the BIU may be defective. Check the BIU. If
the BOD alarm LED is on, replace the BIU. If the BOD LED is
off and the BOK LED is on, a PN’s Maintenance circuit pack
may be incorrectly reporting the problem. Resolve every alarm
against these MOs, and rerun the test.
