Procedure 12-6 (continued)
Adjusting the load sharing for replacement rectifiers
Step Action
5 Adjust the FLOAT voltage of the rectifier that has the lowest current reading
on the rectifier ammeter display by:
• slowly and very slightly adjusting the FLT potentiometer clockwise until
the ammeter reading is no longer the lowest of the installed rectifiers.
Note:
The FLT potentiometer load sharing adjustment is very sensitive. Small
adjustments can reflect large changes in the ammeter readings.
6 Adjust the FLOAT voltage of the rectifier that has the highest current reading
on the rectifier ammeter display by:
• slowly and very slightly adjusting the FLT potentiometer counterclockwise
until the ammeter reading is no longer the highest of the installed
rectifiers.
Note:
The FLT potentiometer load sharing adjustment is very sensitive. Small
adjustments can reflect large changes in the ammeter readings.
7 Repeat from step 4 until all rectifiers have RFA LED illuminated GREEN and
the ammeter displays all read within 0.1 A of each other.
