Alarm
Description
4143
BOOSTER/BATTERY CHARGER
CURRENT MAX
Detection of maximum current in the
booster/battery charger.
The Booster/Battery charger and Inverter will switch
off for protection purposes.
4146
4TH LEG DRIVER FAILURE
The Booster’s driver indicates the presence of a
defect which switches the power off.
4147
BATTERY CHARGER DRIVER FAILURE The Battery charger driver indicates a defect,
switching it off.
4150
BOOSTER OVERTEMPERATURE
The temperature of the booster bridge exceeds the
machine’s set limit or the coil’s sensor is on.
4151
4TH LEG OVERTEMPERATURE
The temperature of the 4
th
leg’s bridge exceeds the
machine’s set limit.
4301
INVERTER FUSES
The alarm signals an Inverter outlet fuses fault,
causing it to switch off immediately.
It may only be manually switched on after the alarm
has ceased.
4304
K7 CLOSING FAILURE
K7 not closed despite a closing command.
Signaled by auxiliary contact.
Load will be supplied by Utility.
4305
K7 OPENING FAILURE
K7 not open despite an opening command.
Signaled by auxiliary contact.
Load will be supplied by Utility.
4307
INVERTER TRANSFORMER
OVERTEMPERATURE
The temperature sensor of the Inverter Transformer
indicates overtemperature.
Elapsed “stop operation” time, Inverter shut-down.
With Utility OK, Load is transferred on Utility.
4308
DC FUSES FAILURE
Blown input DC fuse(s) F1 of the Inverter.
Inverter cannot be started as long as present.
4309
DRIVER FAILURE
An abnormal condition has been detected on one or
more power modules of the Inverter (temperature or
overcurrent).
Inverter shut-down and cannot be started as long as
the alarm is present.
4310
IGBT RECTIFIER DRIVER FAILURE
Indicates a failure on the driver board or the Rectifier
IGBT bridge.
The Rectifier is shut-down.
4311
BOOSTER DRIVER FAILURE
Driver Booster error signal.
4312
INVERTER VOLTAGE OUT
OF TOLERANCE
Inverter Output Voltage is out of the tolerances (
±
10%).
Inverter is switched OFF.
4320
ISMAX DETECTION
Detection of Inverter Bridge (Is) current limit causing
the Inverter OFF and automatic re-start.
After 3 times the Inverter switches-Off, and it can be
restarted manually.
4321
HIGH CURRENT SHARING
A high exchange current value is detected between
the UPS of the Parallel System.
4340
INVERTER CONTROL FAILURE
The “Slave” oscillator is not in synchronized with the
Master; thus causing the shut-down of its 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.
