During battery test the DC voltage falls under the critical
level.
If the boost voltage has not been reached within 24 hours,
then the charge voltage returns to floating voltage.
Battery test is stopped.
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.
Signaled by electronic detector.
Inverter can be started manually after replacement of fuses.
K7 not closed despite a closing command being done.
Signaled by auxiliary contact.
Load will be supplied by mains.
K7 not open despite an opening command being done.
Signaled by auxiliary contact.
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 synchronized with the master, thus
causing the shutdown of it's inverter.
Auto calibration of the Inverters free-run 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.
Signaled by auxiliary contact.
The load cannot be supplied by electronic bypass.
K6 not open despite an opening command being done.
Signaled by auxiliary contact.
The mains bypass voltage is out of the tolerances (±10%).
K6 opens, synchronization with mains is inhibited and
transfer to mains is blocked.
