Problem
Rectifier yellow LED on and
rectifier clicks every 6
seconds.
Rectifier red LED on.
Low system output voltage
(rectifiers not in current
limit.)
Low system output voltage
and rectifier yellow LEDs
are on (rectifiers are in
current limit.)
High system output voltage.

Possible Cause
Rectifier has been shut down.
Very high or low AC voltage, or
AC supply failed.
DC overvoltage
Rectifier failed
Rectifiers off.
Battery Test and/or
Temperature Compensation is
active.
Incorrect float voltage setting at
system controller.
Load is too high for rectifier
capacity.
Battery is recharging after AC
power outage.
Equalize, Fast Charge and/or
Temperature Compensation is
active.
Incorrect float voltage setting at
system controller.
Faulty rectifier.

Maintenance
Required Action
Normal operation. See details.
If required, restart the rectifier.
Power system will return to normal
operation when the AC supply
voltage is within the specified range.
See Specifications on page 59.
Remove and re-insert rectifier(s) or
shut down and restart using DCTools.
Replace the rectifier.
Restore AC power.
Disable active function(s) if not
required.
Check the float voltage setting of the
system controller.
Record new setting.
Install additional rectifiers.
Check battery has recharged within
expected time.
Disable active function(s) if not
required.
Check the float voltage setting of the
system controller.
Record new setting.
Locate the rectifier with the highest
output current and remove this one
first.
If the first rectifier removed is not
faulty, remove each of the remaining
rectifier modules one at a time, until
the faulty rectifier is found. (The
output voltage returns to normal
when faulty rectifier is removed.)
Replace faulty rectifier with one that
is working.
Return the faulty rectifier for service.
