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.
