Cause : Technology controller actual value limited comes when the actual value for the technology controller, interconnected via connector input p2264, has reached a limit.

Fault value (r0949, interpret decimal):
1: upper limit reached.
2: lower limit reached.

- adapt the limits to the signal level (p2267, p2268).
- Check the actual value normalization (p0595, p0596).
- Deactivate evaluation of the limits (p2252 bit 3)
