21.6 Positioner adjustment for end position OPEN (inverse operation)
In standard version the maximum input signal (E1 = 20 mA) results in operation
to end position OPEN.
.
By switching the code switch S3-7 (figure AJ) to position “1”, an inversion of
this signal definition (inverse operation) can be achieved.
.
In case an RWG (option) is installed, the connections 7 (red) and 5 (black) on
the positioner board (figure W) of the actuator have to be exchanged.
.
In case a potentiometer is installed, (option) the connections 21 (red) and 22
(black) at XA (connection for actuator) must be interchanged.
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.
.
Run actuator with push button to end position OPEN .
.
Supply nominal value E1 of 0 or 4 mA (see wiring diagram).
.
Turn potentiometer “t-off” (P10) counterclockwise to the stop
(figure AJ).
Missing signals E1/ E2 or wrong polarity are indicated by LED
(V10) “E1/E2 < 4 mA" (figures AH or AJ)
.
Connect voltmeter to measuring points MP3 and MP4 (figure AJ) 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 in 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.
Adjust position feedback according to clause 16. and 17. and repeat
“positioner adjustment”.
