Lucent Technologies 415B Battery Plant for 4ESS
7 - 28 Retrofit of 415A Battery Plant
Issue 6 September 1999
7. Repeat Steps 4 through 6 for other rectifier.
8. Verify that the rectifiers are off before proceeding.
Current Limit
Adjustment
1. Turn on a rectifier.
2. Set load to 160 amperes and on line. Adjust dummy load if
the 415A plant is less than 160 amperes.
3. Operate the Rect NL/FL switch to FL (full load). The
rectifier should assume a 140A ±2A load. If it does not,
adjust R488 (counter-clockwise to lower, clockwise to
raise) on the 208G circuit pack until it does assume a 140A
±2A load.
4. Operate the Rect NL/FL switch to NL (no load). The
rectifier sheds most of the load and the other rectifiers pick
up most of the load. Adjust the rectifier to 151.9V to match
the 415A System.
5. For a dual module replacement, repeat Steps 1 through 4
for the second rectifier.
VI and VP Test
Leads
Refer to Section 7, Glossary, for the definitions of VI and VP.
1. Before adjusting the VI signal, locate the BJB board inside
the Galaxy controller.
2. Verify that SW202 position #8 is at the “1” or “closed”
position.
3. Configure the controller for rectifiers. You can configure
the rectifiers from the front panel of the Galaxy by doing
the following:
