Adjusting the rectifier and the dc distribution shelf 10-19
Action
Repeat Procedure 10-1 on page 10-4 through Procedure 10-4 on page 10-16
for each rectifier to be adjusted.
Ensure that all rectifiers have been adjusted for HVSD, EQL and FLT.
Turn the dc and ac circuit breakers for all rectifiers to the OFF position.
Turn the dc circuit breaker on the first rectifier to the ON position.
Turn the ac circuit breaker on the first rectifier to the ON position.
Turn the SENSE DIP switch for the first rectifier to the ON position.
Turn the battery string circuit breakers (A1-A4, B2-B4) on the BBP to the ON
position.
Verify the rectifier ac circuit breakers as shown in Table 10-9:
Then perform these steps
• Turn the battery string circuit breakers to the OFF position.
• Turn the FLT potentiometer on the rectifier slowly and
slightly (about 1/2 turn) counter-clock wise.
• Reset the circuit breaker on the rectifier.
• Go to step 7.
• Go to step 9.
Note: All BBP breakers must be in the ON position regardless of whether the
associated battery string is being used.
Allow the batteries to charge for approximately ten minutes.
Slowly adjust the FLT potentiometer on the rectifier clock wise to increase the
float voltage to the normal level (see Table 10-8 on page 10-18).
Repeat from step 3 for rectifiers 2 and 3 if installed.
Go to Procedure 10-6 on page 10-20.
