3.3.4 Assembly procedure (see figure 3-7, page 51)

1. Mount clamping assembly (3) with hexagon socket cap screws

(17) and lock washer (16) on the actuator spindle.

2. Insert the pick-up bracket (2) into the recesses of the clamping

assembly. Set the necessary length and tighten the screws so that

the pick-up bracket can still be shifted.

3. Insert the pin (4) in the lever (6) and assemble with nut (18), spring

washer (14) and washer (12).

4. The value of the stroke range specified on the actuator or if this

does not exist as a scaling value, the next greatest scaling value is

set. The center of the pin must be in line with the scaling value.

The same value can be set later under parameter 3.YWAY in

commissioning to display the way in mm after initialization.

5. Assemble the hexagon socket cap screw (17), spring washer (16),

washer (12) and square nut (19) on the lever.

6. Push the premounted lever onto the positioner axis up to the stop

and fix with the hexagon socket cap screw (17).

7. Fit the mounting bracket (1) with two hexagon head screws (9),

lock washer (10) and flat washer (11) on the rear of the positioner.

8. Selection of the row of holes depends on the width of the actuator

yoke. The pin (4) should engage in the pick-up bracket (2) as close

as possible to the spindle but may not touch the clamping

assembly.

9. Hold the positioner with the mounting bracket on the actuator so

that the pin (4) is guided within the pick-up bracket (2).

10. Tighten the pick-up bracket.
11. Position the mounting parts according to the type of actuator.

-- Actuator with ledge: Hexagon head screw (8), flat washer (11)

and lock washer (10).

-- Actuator with plane surface: Four hexagon head screws (8), flat

washer (11) and lock washer (10).

-- Actuator with columns: Two U bolts (7), four hexagon nuts (21)

with flat washer (11) and lock washer (10).

12. Secure positioner onto the yoke using the previously positioned

mounting parts.

.

NOTE
Set the height of the positioner so that the horizontal lever position is

reached as close to the stroke center as possible. You can use the

lever scale as orientation. It must be guaranteed that the horizontal

lever position is passed through within the stroke range.
