Mounting

The toothed gear pair of the position sensor is held in place by a tension spring (3),

to ensure backlash-free motion when the direction of rotation is reversed.

- set the stop pin to the center position, as shown in Figure 14.

- align the sensor and its gears with the actuator; set the first toothed gear in

09:00 o'clock position (fig. 15) onto the drive shaft gear (4).

- slightly move the sensor back and forth to pre-tension the toothed gears with the

difference "z" until the second toothed gear snaps in.

- fasten the screws (1) tightly.

- fasten sensor cable plug on sensor pcb
