Alarm Description
4105
RECTIFIER OVERTEMPERATURE
Temperature sensor indicates a situation of
overtemperature on the Rectifier bridge.
Only the alarm is given.
The Rectifier
, when in an Off state, cannot start as long as
this condition persists.
4106
RECTIFIER TRANSFORMER
OVERTEMPERATURE
The temperature sensor inside the input transformer
winding indicates overtemperature.
Only the alarm is given.
The Rectifier
, when in an 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 sequence).
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 shut-down.
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
A high ripple is present in the Battery voltage.
4125
HIGH DC-LINK VOLTAGE
Detection of high voltage on the DC-link.
The Rectifier, Booster
and Inverter will switch off for
protection purposes.
The Rectifier may only be switched on again if the DC-
link’s
voltage value falls below 430Vdc.
4126
4
th
LEG CONTROL SATURATION (Imax)
The current in the fourth leg has reached its highest value.
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 the 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.
4141
ISMAX DETECTION RECTIFIER
After 3 IS-Max condition within the time frame specified in
respective parameter, the Rectifier remains shut-down.
4142
RECTIFIER CURRENT MAX
Will cause immediate shut-down of the Rectifier.
Based on the value inserted in the respective parameter.
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, switchi
ng 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.
