An abnormal condition has been detected on one or more
power modules of the Inverter (temperature or over
current).
Inverter shutdown and cannot be started as long as the
alarm is present.
Inverter Output Voltage is out of the tolerances (± 10%).
Inverter is switched OFF.
Detection of Inverter Bridge (Is) current limit causing the
Inverter OFF and possible automatic restart.
After 3 times the Inverter switches-Off, and it can be
restarted manually.
A high exchange current value is detected between the
UPS of the parallel system.
The "Slave" oscillator is not in synchronized with the
Master; thus causing the shutdown of it's Inverter.
If after a restart the condition remains, the LED inside the
Inverter symbol on the panel will not light up, indicating
that this Inverter cannot supply the Load anymore.
Either one or all the fuses in bypass line have blown.
K6 open despite a closing command being issued.
Signaled by auxiliary contact.
The Load cannot be supplied by Automatic Bypass.
K6 closed despite an opening command being issued.
Signaled by auxiliary contact.
A faulty current has been detected in the static-switch
causing the opening of the contactor K6 for 10 seconds.
After 3 times K6 remains definitively open.
The alarm reset can be done only from Service Center.
Temperature sensor indicates an over temperature on the
Static-Switch.
The Utility Bypass Voltage is out of the tolerances (± 10%).
K6 opens, synchronization with Utility is inhibited and
transfer to Utility is blocked.
The Load supplied by Utility exceeds the Inverter power.
The Load remains supplied by Utility until the alarm stays
ON.
A malfunction on the UPS ventilation system was detected.
No change for UPS operation.
Call immediately Service Center for intervention.
Load is locked on Utility because 3 transfers on Utility have
been detected in a short time (default 30 seconds).
The transfer will be free after a time defined in parameter
(default 30 seconds).
Load is transferred to Utility because the error detector
detected a disturbance on the output voltage.
Alarm after detection of an EPO from an external safety
device connected on Customer Interface Board.
Consequently K4, K6, K7 open, Rectifier, Inverter and SSM
are switched Off.
