Symptom
Likely Causes
Action
interference where possible.
“EEPROM Fail” alarm for the
Controller is activated.
Corrupted data found on the backplane
EEPROM that is outside the allowable
data range. (similar to RECTIFIER
corruption above)
Replace the faulty backplane if the
memory cell is confirmed to have failed.
“Range RECTIFIER” alarm for the
rectifier is activated.
Corrupted data found on the EEPROM
inside the rectifier that is inside the
allowable data range but does not match
the value programmed.
Try adjusting the RECTIFIER
parameters to see if the EEPROM cells
can be updated. If not, replace the faulty
rectifier.
6.8 TO REMOVE A RECTIFIER MODULE
Lift the securing latch in the center divider adjacent to the module and pull the module out of the Power plant.
When removing modules, especially if the ambient temperature is high and the unit has been operating at maximum load, avoid skin
contact with the metal casing as it may be too hot to touch. Pull the unit halfway out of the magazine and let cool for 2-3 minutes
before handling.
6.9 TO INSERT A RECTIFIER MODULE
Insert the module into the slot. Push the module all the way in so the rear connector fully mates and the securing latch spring clicks
back down into place.
