Symptom Likely
Causes Action
set too low.
If this alarm comes up during equalize,
the maximum output voltage from the
rectifier may not be high enough to
overcome the system drops to the sense
point and allow the system to regulate at
the desired high equalize voltage.
RECTIFIERs than declared can generate
this problem).
Revise the requirements for high equalize
voltage level.
RECTIFIER “EEPROM Fail” alarm is
activated as indicated at the RECTIFIER
Menu for a particular RECTIFIER.
Corrupted data found on the EEPROM
inside the rectifier that is outside the
allowable data range. The rectifier
software has attempted to over-write and
has failed due to the memory cell being
damaged.
Note: excessive electrical noise can
corrupt the read data transfer, which can
lead to the same alarm being generated.
Replace the faulty rectifier if the memory
cell is confirmed to have failed. This can
be done by, modifying each of the
RECTIFIER parameters on the Controller
and checking to see if the alarm clears.
(EEPROM corrects the data).
Check for EMC problems and
remove/reduce the source of electrical
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 se if the EEPROM cells can be
updated. If not, replace the faulty
rectifier.
6.1
TO REMOVE A RECTIFIER MODULE OR A CONTROLLER
Lift the securing latch in the centre divider adjacent to the module and pull the module out of the Power Module.
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.
6.2
TO INSERT A RECTIFIER MODULE OR A CONTROLLER
Insert the module into the slot and ensure alignment with the fold-out rails in the magazine. Push the module all the way in
so the rear connector fully mates and the securing latch spring clicks back down into place.
