Mounting
The toothed gear pair of the position sensor is held in place by a tension spring (3), to ensure sufficient
free motion when the direction of rotation is reversed.
- fasten sensor cable plug on sensor pcb
- 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 03:00 o'clock position
(see Figure 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
