- Check mechanics and pneumatics in the valve
- Compare the specifications in the Transducer Block, which describe the valve as well as
the actuator and the mechanical structure, with the actual valve.

8.3 Messages of the SELF_CALIB_STATUS parameter (Transducer Block)
Proportional band restricted too much
Even the smallest permissible pulses still cause excessive changes in travel. Initialization
aborted.
Possible sources of error:
– Supply pressure too high
– Signal pressure throttle missing in actuator with a small volume
– Mechanical failure, especially with attachment according to IEC 60534-6 (NAMUR)
– If a booster valve is mounted with an actuator with a large volume, the bypass should
be opened further.
