Adjusting the rectifier and the dc distribution shelf 10-21
Action
Examine all rectifiers for the status of the RFA LEDs (see Figure 10-4 on page
10-10).
Perform the load sharing adjustment steps shown in Table 10-11.
Note: Table 10-11 lists the RFA LED indications and the associated steps to
coarsely adjust the load sharing of multiple rectifiers.
Then the indication
means
that the rectifier with
the GREEN RFA LED
is floating slightly too
high
that the rectifier with
the RED RFA LED is
floating slightly too low
that the rectifiers are
sharing the load
closely
Repeat from step 2 until all rectifiers RFA LED are illuminated GREEN.
—continued—
Then perform these steps
slowly and very slightly adjust the
FLT potentiometer of the rectifier
that has the RFA LED illuminated
GREEN counterclockwise until the
RFA LEDs of at least one of the
other rectifiers illuminate GREEN.
Go to step 3.
slowly and very slightly adjust the
FLT potentiometer of the rectifier
that has the RFA LED illuminated
RED clockwise until the RFA LED
illuminates GREEN.
Go to step 3.
go to step 4.
