Warnings and Alarms
ALARM 243, Brake IGBT
This alarm is only for enclosure size F frequency converters.
It is equivalent to WARNING/ALARM 27, Brake chopper fault.
The report number does not describe the module which
has the failed brake IGBT. The open Klixon can be
identified in the report number.
The report value in the alarm log indicates which power
module generated the alarm:
1 = Left most inverter module.
2 = Middle inverter module in enclosure sizes F12
or F13.
2 = Right inverter module in enclosure sizes F10
or F11.
2 = Second frequency converter from the left
inverter module in enclosure size F14.
3 = Right inverter module in enclosure sizes F12
or F13.
3 = Third from the left inverter module in
enclosure size F14 or F15.
4 = Far right inverter module in enclosure size
F14.
5 = Rectifier module.
6 = Right rectifier module in enclosure size F14 or
F15.
ALARM 244, Heat Sink temperature
This alarm is only for enclosure type F frequency
converters. It is equivalent to ALARM 29, Heat Sink temp.
The report value in the alarm log indicates which power
module generated the alarm:
1 = Left most inverter module.
2 = Middle inverter module in enclosure size F12
or F13.
2 = Right inverter module in enclosure size F10 or
F11.
2 = Second frequency converter from the left
inverter module in enclosure size F14 or F15.
3 = Right inverter module in enclosure sizes F12
or F13.
3 = Third from the left inverter module in
enclosure size F14 or F15.
4 = Far right inverter module in enclosure sizes
F14 or F15.
5 = Rectifier module.
6 = Right rectifier module in enclosure sizes F14
or F15.

Operating Instructions
ALARM 245, Heat Sink sensor
This alarm is only for enclosure size F frequency converters.
It is equivalent to ALARM 39, Heat sink sensor.
The report value in the alarm log indicates which power
module generated the alarm:
The 12-pulse frequency converter may generate this
warning/alarm when 1 of the disconnects or circuit
breakers is opened while the unit is on.
ALARM 246, Power card supply
This alarm is only for enclosure size F frequency converters.
It is equivalent to ALARM 46, Power card supply.
The report value in the alarm log indicates which power
module generated the alarm:
