F30899 (N, A)
Power module: Unknown fault
Reaction:
NONE (DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge:
IMMEDIATELY (power on)
Cause:
A fault occurred on the power module that cannot be interpreted by the control unit firmware. This can occur if the
firmware on the power module is more recent than the firmware on the control unit.
Fault value (r0949, decimal):
Fault number.
If required, the significance of this new fault can be referred to in a more recent description of the control unit.
Remedy:
- replace the firmware on the power module by an older firmware version (r0128).
- upgrade the firmware on the control unit (r0018).

NONE
Acknowledge:
NONE
Cause:
When evaluating the temperature sensor, an error occurred.
Alarm value (r2124, decimal):
1: Wire breakage or sensor not connected (KTY: R > 1630 Ohm).
2: Measured resistance too low (PTC: R < 30 Ohm, KTY: R < 340 Ohm).
Remedy:
- check that the sensor is connected correctly.
- replace sensor.
Reaction upon F:
NONE (DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge
upon F:
IMMEDIATELY
