Possible Problem(s) Possible Solution(s)
MAJ Multiple Rectifier
Fail,
MAJ Battery on
Discharge
Fail
red
(multiple
Rect)
green
Multiple rectifier outputs have
dropped below 18V (36V); rectifiers
have shut down 31 .
1. Reset the rectifiers by removing the rectifiers, waiting
approximately 30 seconds, and replacing the rectifiers.
2. If problem not corrected, replace rectifiers.
• Excessive ambient temperature;
multiple rectifiers have shut
down 31 .
• Multiple rectifiers have failed.
1. Verify that there is no obstruction of the vertical airflow path
and fans are turning.
2. Reset rectifies by removing them, waiting approximately 30
seconds, and replacing them.
3. If problem persists, replace the rectifiers.
4. If problem still persists, call your local field representative.
Fail
red
(all Rect)
green
• All rectifier outputs have dropped
below 18V (36V); all rectifiers
have shut down 31 .
• Defective controller.
1. Remove controller and reset the rectifiers by removing the
rectifiers, waiting approximately 30 seconds, and replacing
the rectifiers.
2. If output voltage does not go to set-point previously set by
user, call your local field representative.
MAJ High Voltage
Fail
red
(multiple
Rect)
green
• High output voltage from
rectifier(s).
• Rectifier(s) high voltage shut
down 31 .
• Internal rectifier(s) failure.
• VHV threshold set below float set
point.
1. Check and adjust VLV threshold to above float set point.
2. Reset the rectifier(s) by removing the rectifier(s), waiting
approximately 30 seconds, and replacing the rectifier(s).
3. If problem persists, replace rectifier(s).
4. If problem still persists, call your local field representative.
31 When a power unit senses an over- or under-voltage condition it will shutdown, wait 10 seconds, and then attempt to restart. If the over- or under-voltage condition
remains it will cycle again. If the over- or under-voltage condition remains after 3 restart attempts the power unit will lock out, and user intervention is required to restart.
