2000 50A -48V 364A-3 SR Series Rectifier
Issue 6 January 1997
Maintenance 7 - 3
3. If the rectifier’s current does not increase when the RECT
TEST switch is in the FL position, turn the applicable
potentiometer (FL or EQ) fully CW. If the rectifier is still
producing no current, press and hold the RECT TEST
switch in the FL position. If the rectifier's current does not
increase, replace the rectifier according to procedures
outlined in Section 5, Installation. If the rectifier's current
does increase, readjust its output according to the
procedures outlined in Section 5, “Initial Start-up and
Check.”
Lamp Test
The following test may be used to determine if all front panel
LEDs and the display are functioning properly.
1. Place the rectifier in the STBY mode.
2. Press the NL/FL switch in either direction.
3. While the NL/FL switch is pressed, all front panel LEDs
should be illuminated and the meter should light and
display “-1888.”
Diagnostics
Introduction
This section diagnoses possible problems that may occur with
the rectifier subsystem. Use the flow chart in Figure 7-1 to
isolate the malfunction to the defective replaceable components
or assembly.
With the exception of fan replacement, the 364A3 rectifier is
designed to be repaired only at a Lucent Technologies factory.
The RSA for the 364A3 rectifier can be replaced in the field.
Diagnostics consist of determining whether or not the rectifier
Note
It is normal for rectifiers not in load share to share load very
unevenly; it is also possible that the rectifiers are misadjusted.
Rectifiers operating with load share disabled can be adjusted
with the circuit breaker closed. Rectifiers may also be
adjusted so that some carry the majority of the load with
remaining units functioning as “hot” spares.
