Code Alarm Meaning
4301 INVERTER FUSES FAILURE
Inverter output fuses blown.
Signaled by electronic detector.
Inverter can be started manually after replacement of
fuses.
4304 K7 CLOSING FAILURE
K7 not closed despite a closing command being done.
Signaled by auxiliary contact.
The load will be supplied by utility.
4305 K7 OPENING FAILURE
K7 not open despite an opening command being done.
Signaled by auxiliary contact.
The load will be supplied by utility.
4312
INV. VOLTAGE OUT
OF TOLERANCE
Inverter output voltage is out of the tolerances defined in
respective parameter (±10%).
Inverter is switched OFF.
4320 ISMAX DETECTION
Detection of inverter bridge (Is) current limitation cause
inverter OFF and possible automatic restart.
After 3 times inverter switches OFF for persistent Is max
detection in time.
Inverter switch OFF, and it can be restarted manually.
4340 INVERTER CONTROL FAILURE
The slave oscillator is not synchronized with the master,
thus causing the shutdown of it’s inverter.
4347 OSCILLATOR FAILURE
Auto calibration of the Inverters free run frequency was not
possible.
The oscillator frequency of this unit is out of tolerance.
4402
RECTIFIER CANNOT BE
TURNED ON
The rectifier cannot be turned on because the DC link
voltage has not reached the requested value.
4404 K6 CLOSING FAILURE
K6 not closed despite a closing command being done.
Signaled by auxiliary contact.
The load cannot be supplied by electronic bypass.
4405 K6 OPENING FAILURE
K6 not open despite an opening command being done.
Signaled by auxiliary contact.
4410
BYPASS UTILITY OUT
OF TOLERANCE
The utility bypass voltage is out of the tolerances (±10%).
K6 opens, synchronization with utility is inhibited and
transfer to utility is blocked.
4520 NO INVERTER POWER
The load supplied by utility is over 100%.
The load remains blocked on utility as long as alarm
overload is active.
4530 LOAD LOCKED ON UTILITY
Load is locked on utility because 3 transfers on utility 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).
4531
LOAD ON UTILITY
BY ERROR DETECTOR
Load is transferred to utility because the error detector
detected a disturbance on the output voltage.
4563 EMERGENCY OFF ACTIVATED
Alarm after detection of an Emergency OFF from an
external safety device connected on Customer Interface.
Consequently K4, K6 and K7 open and shut down inverter,
booster and rectifier.
4570 OVERLOAD
The UPS-System is in an overload condition >125% on
inverter, or >150% on utility.
A sequence of “stop operation” starts.
Time out depending on load quantity.
