Action
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.
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.
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.
