Assembly Sequence

(see Figure 3, page 50)

Mount clamping assembly (3) with socket cap screws (17) and lock washers (16) on the actuator spindle.

Insert the pick-up bracket (2) into the recesses of the clamping assembly. Set the required length and

screw only so tight that the pick-up bracket can still be shifted.

The center of the pin (4) is set to the value of the stroke range specified on the actuator or set to the

next large scale value. The same value can be set later for 3.YWAY during start-up, to display the travel

in mm after initialization.

Push the lever onto the positioner shaft as far as possible, and secure with the socket cap screw (17).

Fit the mounting bracket (1) with two hexagonal head screws (9), lock washer (10) and flat washer (11)

on the rear of the positioner.

Selection of the row of holes depends on the width of the actuator yoke. The roll (5) should engage in the

pick--up bracket (2) as close to the spindle as possible, but must not touch the clamping assembly.

Hold the positioner with the mounting bracket on the actuator such that the roll (5) is guided within the

pick-up bracket (2).

Tighten the pick-up bracket.

Position the mounting parts according to the type of actuator.

-- Actuator with ledge: hexagonal head screw (8), flat washer (11) and lock washer (10).

-- Actuator with plane surface: four hexagonal head screws (8) with flat washer (11) and lock washer (10).

-- Actuator with columns: two U-bolts (7), four hexagonal nuts (21) with flat washer (11) and lock

washer (10).

10. Secure positioner onto the yoke using the previously positioned mounting parts.

NOTE

Adjust the height of the positioner such that the horizontal lever position is reached as close as possible

to the center of the stroke. You can use the lever scale of the actuator for orientation. It must always

be guaranteed that the horizontal lever position is passed through within the stroke range.
