Positioning pressure 1 for single-action and double-action actuators
Y2
Positioning pressure 2 for double-action actuators

Commissioning (see Leaflet "Operation – a concise overview")
Because of the numerous applications it can have, the positioner must be adapted to the actuator after assembly
(initialized). This initialization is largely automatic. The positioner calculates the direction of action, the travel and
the angle or rotation and the travel times of the actuator one after the other.
Before initialization, you only have to set a few parameters for the positioner. The remaining parameters are set
with default values that you do not normally have to alter. If you observe the following points, you will not have
any problem with commissioning.
Tip: You can return to the previous parameter by pressing the

Preparation for linear actuators
1.
Mount the positioner with the appropriate mounting kit (see Section 3.2).
Note
The position of the leverage ratio switch in the positioner is especially important (7, Leaflet "Opera-
tion – a concise overview"):

5 to 20 mm
25 to 35 mm
40 to 130 mm
2.
Push the driver pin (4, Fig. 1, 2) on the lever (6, Fig. 1, 2) to the scale position corresponding to the nominal
stroke or the next highest scale position and screw the driver pin tight with the nut (18, Fig. 1, 2).
3.
Connect the actuator and positioner with the pneumatic cables and supply pneumatic power to the positioner
(see Fig. 16).
4.
Connect a suitable current or voltage source (see Figs. 5 and 6 or Fig. 9 of PROFIBUS PA).
5.
The positioner is now in "P manual" mode. On the upper line of the display, the current potentiometer voltage
(P) is displayed as a percentage, e.g. "P12.3", and on the lower line "NOINIT" is blinking:
6.
Check that the mechanism is able to move freely over the entire setting range by moving the actuator into
each final position with the
Tip: You can move the actuator quickly by pressing the other direction key while you hold the first direction
key down.
