Code Message Meaning
4111 RECTIFIER UTILITY OK
Rectifier input utility is again within the acceptable
tolerance (voltage, frequency and phase).
4114
UPS SHUTDOWN
(LOW BATTERY 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 RECTIFIER 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 utility out of tolerance / EPO / DC-Voltage 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:
-
Over temperature
-
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 utility (voltage out of tolerance, not
synchronizing, bypass blocked).
4361 INVERTER ON
The command to start the inverter has been activated on
the control panel.
4362 INVERTER OFF
The command to switch OFF the inverter has been done by
the control panel or automatically for alarm detection.
4411 BYPASS UTILITY OK
Bypass input utility is again within the admitted tolerance
(Voltage, frequency and phase).
4500 COMMAND TOTAL OFF
Disconnection of the load by opening K4, K6 and K7 for:
EPO / Total Off / Overload / Stop operation.
4521 NO BYPASS POWER
With the load supplied by electronic bypass, a utility failure
or K6 opening occurred.
4534 MULTIPLE LOAD TRANSFER
2 transfers inverter-utility have been detected in a short
time, defined by respective parameter (default 30 seconds).
