6.2.2 Messages list
Are defined messages: all the recorded events which are referred to the operation status coherent
with the normal situation of the UPS.
Code Message Meaning
4111
RECTIFIER
MAINS OK
Rectifier input mains is again within the admitted tolerance
(voltage, frequency and phase).
4114
UPS SHUTDOWN
(LOW BATT VOLTAGE)
The UPS is in Load OFF status, resulting in Battery supply for the
power supply.
Should the Battery voltage decrease to a value below of the one
set in a parameter, then power supply will shutdown to avoid
damage to the Battery
4119
BATTERY TEST
STARTED
Start of manual or automatic battery test.
Rectifier output voltage is decreased to the value defined by
respective parameter.
4120
BATTERY TEST
STOPPED
End battery test.
End of manual or automatic battery test.
Rectifier output voltage is restored to floating voltage.
4141
ISMAX DETECTION
BOOSTER
Detection of persistent booster (Is) current limitation.
4161
RECTIFIER
ON
Rectifier received the command to switch ON.
4162
RECTIFIER
OFF
Rectifier received the command to switch OFF for:
input mains out of tolerance / EPO / UDC max.
4163
GENERATOR
ON
Customer Interface (X1 / 11, 22) received a Gen set ON signaling.
Operating mode dependent on setting of respective parameters.
4164
GENERATOR
OFF
Customer Interface (X1 / 11, 22) received a Gen set OFF
signaling.
Function bypass enabled dependent on setting of respective
parameter.
4302
INVERTER
CANNOT BE
TURNED ON
Inverter cannot be switched on because one of the following
conditions are still present:
• Overtemperature;
•
Low battery voltage;
• Inverter fuses;
•
Overload;
• K7 opening failure;
• High battery voltage;
• DC low;
• EPO (Emergency Power Off).
4303
INVERTER
CANNOT BE
TURNED OFF
Inverter cannot be switched OFF, because the load cannot be
transferred on mains (voltage out of tolerance, not
synchronizing, bypass blocked).
4361
INVERTER
ON
The command to start the inverter has been activated on the
control panel.
