Problem 
Possible Cause/s 
Required Action 
Rectifier power limit is active.  Check if the power system is 
recovering from a recent AC 
power outage. The power system 
may still be charging the 
batteries after the power outage.  
No further action is required. 
Check that the rectifier capacity 
of the power system is not 
exceeded. Additional rectifiers 
may be required. 
Rectifier yellow LED 
on 
Rectifier temperature 
turndown is active, due to 
low AC supply voltage or 
excessive ambient 
temperature. 
None.  The power system will 
return to normal operation when 
the AC supply has returned to 
within its rated AC input voltage 
or operating temperature range, 
as specified in Appendix C. 
Equalize, Fast Charge and/or 
Temperature Compensation 
process is active 
Disable active processes if not 
required. 
Incorrect float voltage setting 
at supervisory module 
Check the float voltage setting of 
the supervisory module. 
Record new setting. 
High system output 
voltage 
Faulty rectifier 
Remove rectifier modules one at 
a time.  (The output voltage 
returns to normal when faulty 
rectifier is removed.) 
Replace faulty rectifier. 
Rectifiers not on 
Restore AC power. 
Battery Test and/or 
Temperature Compensation 
process is active. 
Disable active processes if not 
required. 
Low system output 
voltage (rectifiers not 
in current limit) 
Incorrect float voltage setting 
at supervisory module. 
Check the float voltage setting of 
the supervisory module. 
Record new setting. 
Load is too high for rectifier 
capacity. 
Reduce load or add rectifier 
modules. 
Low system output 
voltage and rectifier 
yellow LEDs are on 
(rectifiers are in 
current limit). 
Battery is recharging after AC 
power outage. 
Check battery has recharged 
within expected time.
