3.6.1 Preparations for linear actuators

1. Assemble the positioner with the appropriate mounting kit (see

chapter 3.3.3, page 39).

.

NOTE
Particularly important is the position of the gear transmission switch (8,

figure 2-1, page 16) in the positioner:

Stroke

Lever

Position of the gear transmission

switch

5 to 20 mm

short

33° (i.e. down)

25 to 35 mm

short

90° (i.e. up)

40 to 130 mm

long

90° (i.e. up)

2. Push the carrier pin (4, figure 3-6 (page 41) 2) onto the lever (6,

figure 3-6, 2) to the scale position corresponding to the rated

stroke or next highest position and screw the carrier pin tight with

the nut (18, figure 3-6, 2).

3. Connect the actuator and the positioner with the pneumatic lines

and supply pneumatic power to the positioner (figure 2-3 and 2-4,

page 18 ).

4. Connect a suitable current or voltage source (see figure 3-12,

page 49 and figure 3-13, page 50).

5. The positioner is now in the operating mode ”P-manual opera-

tion” The current potentiometer voltage (P) is displayed in percent

in the top line of the display, e.g.: ”P12.3”, and ”NOINI” flashes in

the bottom line:

6. Check the free running of the mechanics in the whole actuating

range by moving the actuator with the keys

and

and driving

to the respective end position.

.

NOTE
You can move the actuator quickly by pressing the other direction key

additionally whilst keeping the direction key selected first pressed.

7. Now move the actuator to the horizontal position of the lever. A

value between P48.0 and P52.0 should be visible in the display. If

this is not the case, adjust the slip clutch (8, figure 2-10, page 27)

until ”P50.0” is displayed with a horizontal lever. The more

accurately you hit this value, the more exactly the positioner can

determine the path.
