Code Alarms Meaning
4115
LOW BATTERY
VOLTAGE
The Battery has been discharged and reached “stop operation”
time-out (default 3 minutes), and the Inverter will be shut down.
It will restart automatically only when the Battery has recharged
enough for a minimum runtime.
4116
HIGH BATTERY
VOLTAGE
Dangerous high DC Voltage caused Inverter shutdown.
Inverter restarts automatically after Battery returns to floating
voltage.
4117
BATTERY
EARTH FAULT
A leakage current to earth has been detected on the DC circuit.
4118 BATTERY FAULT
During battery test the voltage falls under the critical level
(depending setting parameters).
Battery test is stopped.
4130
TURN ON RECT.
OR SHUTDOWN UPS
Rectifier and Inverter are OFF.
The DC power supply is discharging the Battery.
Rectifier must be restarted or Battery must be disconnected in
order to avoid damage.
4140
RECTIFIER
CONTROL FAILURE
Rectifier Voltage hasn’t reached the set value (probably fault on
regulation loop).
LED Rectifier on control panel is blinking.
4301
INVERTER
FUSES FAILURE
Inverter Output Fuses blown (F5, F6 and F7).
Inverter can be started manually after replacement of the fuses.
4304
K7 CLOSING
FAILURE
K7 not closed despite a closing command being issued.
Signalled by auxiliary contact.
Load will be supplied by Utility.
4305
K7 OPENING
FAILURE
K7 not open despite an opening command being issued.
Signalled by auxiliary contact.
Load will be supplied by Utility.
4307
INVERTER
TRANSFORMER
OVERTEMPERATURE
The temperature sensor of the Inverter Transformer indicates
over temperature.
Elapsed “stop operation” time, Inverter shutdown.
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 over current).
Inverter shutdown and cannot be started as long as the alarm is
present.
4312
INV. 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.
4340
INVERTER
CONTROL FAILURE
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.
4404
K6 CLOSING
FAILURE
K6 open despite a closing command being issued.
Signalled by auxiliary contact.
The Load cannot be supplied by Automatic Bypass.
