Problem Possible Cause Required Action
Rectifier yellow LED on. Rectifier power limit or current
limit is active.
Power system is charging the batteries.
If required, activate the Battery Current
Limit control process.
Load current exceeds the total
rectifier capacity.
Install an additional rectifier if possible.
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 138.
EFX48 system controller has
shut down the rectifier.
(Depending on model, rectifier
may also click every 5-15
seconds.)
Normal operation. See Rectifier
Shutdown on page 107.
If required, restart the rectifier.
Rectifier red LED on. Very high or low ac voltage, or
ac supply failed.
Power system will return to normal
operation when the ac supply voltage is
within the specified range. See
Specifications on page 138.
DC overvoltage Remove and re-insert rectifier(s).
Internal rectifier fault. Replace the rectifier.
Low system output voltage
(rectifiers not in current
limit).
Rectifiers off. Restore the ac supply.
Temperature Compensation is
active and the battery
temperature is above the
reference temperature.
None. This is normal operation (if
batteries are connected). Disable
Temperature Compensation if no
batteries connected.
Battery Test is active. None. Output voltage will return to
normal when Battery Test is completed.
Incorrect float voltage setting in
EFX48.
Correct the float voltage setting of the
EFX48.
Record new setting.
Low system output voltage
and rectifier yellow LEDs
are on (rectifiers are in
current limit).
Load is too high for rectifier
capacity.
System has been sized incorrectly. Check
system sizing in comparison to maximum
load requirements.
Battery is recharging after ac
supply failure.
Check battery has recharged within
expected time.
