PME120-AI / PME120-AN (Contrac)
ELECTRICAL ROTARY ACTUATOR | SEI/PME120-EN REV. A
… 7 Exchange of position sensor
Mounting
Figure 34: Position sensor / Mounting position (example shows PME120-AN)
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.
1. Set the stop pin to the center position, as seen in
Figure 34
.
2. Connect the plug of the cable
2
to the sensor pcb.
3. Align the sensor and its gears with the actuator; set the first
toothed gear in 11:00 o’clock position (see
Figure 34
) onto
the drive shaft gear
4
.
4. Slightly move the sensor back and forth to pre-tension the
toothed gears until the second toothed gear snaps in.
5. Fasten the screws
1
tightly.
6. Fasten the rear cover (or cover with electronic unit for
PME120-AI if applies).
7. Finally readjust the actuator range as described in the setup
section of the actuator and / or electronic unit instruction
manual.
