Alarm messages
DC Bus voltage error
(1)
Description The voltage of the internal DC bus has exceeded the limit.
Corrective
action
This is a condition that can be destructive for the device. Check that the AC voltage quality and levels
meet the requirements specified in this manual and disconnect the device if they do not.
DC+ Bus overvoltage
(1)
Description The voltage of the internal DC+ bus has exceeded the limit.
Corrective
action
This is a condition that can be destructive for the device. Check that the AC voltage quality and levels
meet the requirements specified in this manual and disconnect the device if they do not.
DC- Bus overvoltage
(1)
Description The voltage of the internal DC- bus has exceeded the limit.
Corrective
action
This is a condition that can be destructive for the device. Check that the AC voltage quality and levels
meet the requirements specified in this manual and disconnect the device if they do not.
Overcurrent L1/L2/L3
Description The SVGm current is too high.
Corrective
action
This alarm may be associated with transients and noise in the power supply voltage. Check the quality
of the power supply voltage. If it continues, contact the Technical Service.
Mains overvoltage L1/L2/L3
Description The mains voltage is too high.
Corrective
action
This alarm may be associated with transients and noise in the power supply voltage, or with incorrect
mains voltage values. This is a condition that can be destructive for the device. Check the configura-
tion. Check the quality of the power supply voltage and disconnect the device if the requirements in
the manual are not met. If it continues, contact the TAS.
IGBT failure
Description IGBT overcurrent.
Corrective
action
Condition that can be destructive for the device. Contact the TAS.
High temp IGBT
Description The temperature of the power module is very high.
Corrective
action
Check that the fans are working. Clean or replace them if necessary. If it continues, contact the Tech-
nical Service.
High temp Inductor
Description The temperature of the inductors is very high.
Corrective
action
Check that the fans are working. Clean or replace the fans if necessary. If it continues, contact the
Technical Service.
DC Bus charge failure
(1)
Description The DC bus has not been pre-charged.
Corrective
action
Check AC connection and voltages. If it persists, contact TAS.
Initial Conditions
Description The start-up conditions have not been met 10 times during the past 5 minutes.
Corrective
action
Check the configuration and the ambient temperature. Check the quality of the power supply voltage.
If it persists, contact the Technical Service.
