Fault
Possible Cause
Suggestion/Solution
High System
Voltage
Module failure.
System voltage exceeds the set limit.
Replace the faulty module.
Check the High Voltage Alarm limit
setting.
Mains Error
AC supply OFF on one rectifier in the
system with one plugged in rectifier.
AC supply OFF on at least two
rectifiers in the system with minimum
two plugged in rectifiers.
Verify that the rectifier position 1 has
a rectifier installed.
Verify AC input connection.
AC Low Voltage
AC voltage drops below the set limit. Verify the Low AC voltage limit
setting.
Verify AC Input connection.
Verify AC Input voltage.
AC High
Voltage
AC voltage rises above the set limit.
Verify the High AC voltage limit.
Verify the AC Input voltage.
Module Failure
Faulty module.
AC OFF on a single rectifier (if more
than one rectifier is installed).
Rectifier current sharing fault.
Low DC output voltage, over-voltage
shutdown, module fan failure, module
is overheated.
Check if module sends alarm flag.
Verify the AC voltage to the failed
module.
Re-insert the faulty module, wait for
30 seconds
Replace the faulty module.
Urgent Module
Failure
More than one rectifier is reporting
Module failure.
See Module failure alarm.
High Load
Faulty module .
Rectifier load current exceeds the set
High load limit [%].
Compare the load current with
installed rectifier capacity.
Add a rectifier or reduce load.
Verify the High load limit setting.
Replace the faulty module.
Over-voltage
Shutdown
Faulty module
Re-insert the module, wait for 5
minutes.
Replace the faulty module.
