Problem
Possible Cause
Required Action
Rectifier power limit or current
limit is active.
Power system is charging the
batteries.
Load current exceeds the total
rectifier capacity.
Install additional rectifiers.
Rectifier yellow LED on.
Rectifier temperature turndown
is active due to low ac supply
voltage or high ambient
temperature.
Power system will return to normal
operation when the ac supply voltage
and/or ambient temperature are
within the specified ranges. See
Specifications on page
.
Rectifier yellow LED on and
rectifier clicks every 5-15
seconds.
Rectifier has been shut down.
Normal operation. See details in the
System Controller Operation
Handbook.
If required, restart the rectifier.
Very high or low ac voltage, or
ac supply failed.
Rectifier will return to normal
operation when the ac supply voltage
is within the specified range. See
Specifications on page
.
DC overvoltage
Remove and re-insert rectifier(s) or
shut down and restart using
DCTools/Web
.
Rectifier red LED on.
Rectifier failed
Replace the rectifier.
Rectifiers off.
Restore the ac supply.
Temperature Compensation is
active.
This is normal if batteries are
connected and the battery
temperature is above the reference
temperature.
Disable Temperature Compensation
if no batteries are connected.
Battery Test is active.
Disable Battery Test if not required.
Low system output voltage
(rectifiers not in current
limit).
Incorrect float voltage setting at
system controller.
Correct the float voltage setting of the
system controller.
Record new setting.
Load is too high for rectifier
capacity.
Install additional rectifiers. See
System and Rectifier Selection on
page
.
Low system output voltage
and rectifier yellow LEDs
are on (rectifiers are in
current limit).
Battery is recharging after ac
supply failure.
Check battery has recharged within
expected time.
