13.2 Troubleshooting
Error Error cause Troubleshooting
Programming error no stroke No compressed air supply during the pro-
gramming procedure
Ensure the compressed air supply avail-
ability, re-programme
Compressed air supply during the pro-
gramming procedure not sufficient
Ensure the compressed air supply avail-
ability, re-programme
No mounting kit available or faulty Check the mounting kit, re-programme
Programming error stroke < min. stroke Minimum stroke was not reached (e.g.
due to stroke limiter)
Ensure minimum stroke, re-programme
Shut off diaphragm compressed too
much (diaphragm size 8)
Ensure correct compression of the shut
off diaphragm, re-programme
Programming error after sensor error The sensor range was exceeded during
the programming procedure. Currently
the process valve is in the valid sensor
range.
Check the mounting kit, re-programme.
Note the maximum stroke (see "Tech-
nical data")
Sensor error CLOSED or OPEN position Sensor limit exceeded Check the mounting kit, re-programme.
Note the maximum stroke (see "Tech-
nical data")
Short-circuit - signal output OPEN or
CLOSED
Short-circuit Check the wiring and device version
Communication error Communication disturbed or interrupted Check the wiring
Supply voltage too low Supply voltage too low Ensure supply voltage in accordance with
chapter "Technical data"
