21.3 Positioner adjustment for end position CLOSED (standard version)
Before beginning the setting of the positioner, it has to be
ensured that the limit and torque switching of the actuator as
well as the feedback have been set (clauses 16. and 17.).
.
Set selector switch (local controls) to position LOCAL.
.
Move multi-turn actuator by pressing push button to
end position CLOSED .
.
Supply nominal value E1 of 0 or 4 mA (see wiring diagram).
.
Turn potentiometer “t-off” (P10) counterclockwise to the stop
(figure AG).
Missing signals E1/ E2 or wrong polarity are indicated by LED
(V10) “E1/E2 < 4 mA" (figures AE or AG)
.
Connect voltmeter to measuring points MP3 and MP4 (figure AG) for measur-
ing the nominal value (0 – 5 V).
For a nominal value E1 of 0 mA, the voltmeter shows 0 V.
For a nominal value E1 of 4 mA, the voltmeter shows 1 V.
In case nominal value (0 V or 1 V) is not correct:
Correct nominal value signal from control room.
.
Connect voltmeter to measuring points MP2 and MP1 for measuring the
actual value signal.
For an actual value E2 of 0 V, the voltmeter shows 0 V.
For an actual value E2 of 5 V, the voltmeter shows 1 V.
If measured value is not correct:
Adjust position feedback according to clause 16. and 17. and repeat
“positioner adjustment”.
