Status messages
Cause
Elimination
Cross reference
Bad - Out of Service
Mode of block is "Out of
Service"
Specify target mode "AUTO".
See section 6.5.5 and
"Diagnosis messages".
Bad - Device Failure
Hardware error
Send device to
Fuchs for repair.
Bad - Sensor Failure,
Low limited
Lead interruption sensor Determine the affected sen-
sor in the device from the
"Sensor Lead Fault" parame-
ter.
See " lead error sen-
sor".
Bad - Sensor Failure,
High limited
Lead short circuit sen-
sor
Determine the affected sen-
sor in the device from the
"Sensor Lead Fault" parame-
ter.
See " lead error sen-
sor".
Bad - Sensor Failure
"Position detection fail-
ure"; the signal combi-
nation of the PFCs is
not assigned to a valve
position
• Check parameterisation of
"Sensor Usage".
• Check PFCs for proper
functioning.
See "diagnosis mes-
sages" and section
6.5.4.
Bad - Non Specific
This value is not used
due to the current
parameterisation
Check parameterisation of
"Sensor Usage".

Cross
reference
The transducer
block does not
leave the "Out of
Service" mode
There is a block configuration
error which is signalled in
"BLOCK_ERR"
Parameterise the "Actuator Fail
Action", by entering the drive mode
"self-closing" or "self-opening".
See section
6.5.3 and 7.3
„BLOCK_ERR“.
The resource block is in "Out of
Service" mode
Set resource block into "AUTO"
mode.
Auxiliary valve
not controlled
The reference value specified
by the DO function block has
the status "bad" or "uncertain"
Check reference value, correct, if
necessary.
See section
6.6.1.
Transducer block is in "Out of
Service" mode
Set transducer block into "AUTO"
mode.
Hardware or lead error
Check diagnosis messages.
Simulation is switched ON in
function block
Switch OFF simulation.
See section
5.4.2 and
Appendix B.
