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 49).
Missing signals E1/E2 or wrong polarity are indicated by
LED (V10) “E1/E2 < 4 mA" (figures 47 or 49)
.
Connect voltmeter to measuring points MP3 and MP4 (figure 49) for mea-
suring 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 mA, the voltmeter shows 0 V.
For an actual value E2 of 4 mA, the voltmeter shows 1 V.
If measured value is not correct:
Adjust position feedback according to clause 16. and 17. and repeat
“positioner adjustment”.
