21.7 Positioner adjustment end position CLOSED (inverse operation)
.
Run actuator with push button
(local controls) to
end position
CLOSED.
.
Connect voltmeter to measuring points MP2 and MP1 for measuring the
actual value E2:
When position feedback is set correctly, the voltmeter shows 5 V.
If measured value is not correct:
Adjust position feedback according to clauses 16. and 17. and repeat
“positioner adjustment”.
.
Connect max. command signal (nominal value E1) = 20 mA.
.
Connect voltmeter to measuring points MP4 and MP3 for measuring the
nominal value E1:
For a nominal value of 20 mA, the voltmeter shows 5 V.
If measured value is not 5 V:
Check the externally supplied command signal E1.
