NOTE:
Verify proper limit switch setting prior to positioner calibration.
Calibration Procedure
Positioner adjustment end position CLOSED (standard version)

Prior to the positioner setting it has to be ensured that the limit and torque switching of the
actuator as well as the position feedback have been set.
•
Set selector switch (local controls) to position LOCAL.
•
Run actuator by pressing push-button
to
end position CLOSED
.
•
Supply nominal value E1 of 0 or 4 mA (see wiring diagram).
•
Turn potentiometer P10 (t
off
) counter-clockwise to the stop (Figure 3).
NOTE:
Missing signals E1/E2 or wrong polarity are indicated by LED V10 ”E1/E2 < 4 mA” (Figure 3)
Possible LED indication:
(refer to Figure 3)
Required setting in end position CLOSED
(refer to Figure 3)
LEDs are not illuminated
Turn potentiometer ”0” (P3) slightly clockwise until
LED
(V27 yellow) lights up.
LED
(V28 green) is
illuminated
Turn potentiometer ”0” (P3) slightly clockwise until LED
(V28
green) goes out and LED
(V27 yellow) lights up.
If
LED
(V27 yellow) is
illuminated
Then
Turn potentiometer ”0” (P3) counter-clockwise until LED
(V27yellow) goes out.
Then turn potentiometer ”0” (P3) slightly clockwise until LED
(V27 yellow) lights up again.
Positioner adjustment end position OPEN (standard version)
•

Possible LED indication:
(refer to Figure 3)
Required setting in end position OPEN
(refer to Figure 3)
LEDs are not illuminated
Turn potentiometer ”max” (P4) slightly counter-clockwise until
LED
(V28 green) lights up.
LED
(V28 green) is
illuminated
Turn potentiometer ”max” (P4) clockwise until LED
(V28
green) goes out.
Then turn potentiometer ”max” (P4) slightly counter-clockwise
until LED
(V28 green) lights up again.
If
LED
(V27 yellow) is
illuminated
Then
Turn potentiometer ”max” (P4) slightly counter-clockwise until
LED
(V27 yellow) goes out and LED
