Rectifier and inverter are OFF.
The DC power supply is discharging the battery slowly.
Rectifier must be restarted or battery must be disconnected
in order to avoid damages.
Rectifier voltage hasn't reached the set value.
Probably fault on regulation loop.
The DC capacitors are not equally charged (more of 50 Vdc
of difference).
The rectifier is switched OFF.
Inverter output fuses blown.
Signalled by electronic detector.
Inverter can be started manually after replacement of
fuses.
K7 not closed despite a closing command being done.
Signalled by auxiliary contact.
The load will be supplied by mains.
K7 not open despite an opening command being done.
Signalled by auxiliary contact.
The load will be supplied by mains.
Inverter output voltage is out of the tolerances defined in
respective parameter (±10%).
Inverter is switched OFF.
Detection of inverter bridge (Is) current limitation cause
inverter OFF and automatic restart (message 320).
After 3 times inverter switches OFF for persistent Is max
detection in time.
Inverter switch OFF, and it can be restarted manually.
The slave oscillator is not synchronised with the master,
thus causing the shutdown of it's inverter.
Auto calibration of the Inverters freerun frequency was not
possible.
The oscillator frequency of this unit is out of tolerance.
The rectifier cannot be turned on because the DC link
voltage has not reached the requested value.
K6 not closed despite a closing command being done.
Signalled by auxiliary contact.
The load cannot be supplied by electronic bypass.
K6 not open despite an opening command being done.
Signalled by auxiliary contact.
The mains bypass voltage is out of the tolerances (±10%).
K6 opens, synchronisation with mains is inhibited and
transfer to mains is blocked.
The load supplied by utility is over 100%.
The load remains blocked on utility as long as alarm
overload is active.
Load is locked on mains because 3 transfers on mains have
been detected in a short time (default 30 seconds).
Transfer will be free again after a time defined by
respective parameter (default 30 seconds).
