Code Alarms Meaning
4106
RECTIFIER TRANSFORMER
OVERTEMPERATURE
The temperature sensor inside the input transformer
winding indicates over temperature.
Only the alarm is given.
The Rectifier, when in Off state, cannot start as long as this
condition persists.
4110
RECTIFIER UTILITY OUT
OF TOLERANCE
Rectifier Input Utility is out of tolerance (voltage, frequency
or phase).
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.
4121 HIGH DC RIPPLE
There is a high voltage ripple on the DC Bus.
Rectifier might be working in current limiting mode.
Decrease the load to stabilize DC Bus.
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.
4165 INPUT FILTER FAILURE
An unbalancing on the three-phase current absorbed by
the input harmonic filters 5th or 11th is detected causing
the opening of the contactors C50 or C110.
The reset alarm can be done only from Service Center.
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.
Signaled by auxiliary contact.
Load will be supplied by Utility.
4305 K7 OPENING FAILURE
K7 not open despite an opening command being issued.
Signaled 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.
