2.2.1.
Direction of the motor during extension of the cylinder
Figure 10: Direction of the motor during extension of the cylinder
With parallel drive (please refer to Figure 10) the turning direction of the motor is
reversed in comparison to the direct drive configuration!
2.2.2.
Sensors
All electro cylinders feature a permanent magnet in the spindle nut. It activates the
sensors which are mounted in the special mounting grooves on one side of the
cylinder.
Sensors and limit switches: see ETH catalogue
(solutions.parker.com/ETH_support).
2.2.2.1
Sensor mounting
Sensors can be inserted into all grooves on the ETH electro cylinder.
If no sensors are mounted by the manufacturer (on customer request), please
remove the groove protection covers. Use a sharp screwdriver to lever the ends
of the covers off the grooves. Pull the entire covers out manually.
Install the sensors. The sensors can be inserted into the grooves from above.
The cable ends should lead into the motor direction. Push the sensors to their
approximate positions in the grooves of the cylinder body. Tighten the fixing
screws on the limit switches slightly and lead the cable along the profile groove.
If sensors are used as end limits (see page 22), do set them.
You can use the formerly removed protective covers in order to fix the sensor
cables. Please cut the covers to the desired length. A pair of scissors may be
used. Please cut off an additional 5 to 10 mm, where the cables are to be lead
out of the profile (please refer to Figure 12).
Insert the cables into the grooves of the plastic covers and push the cover into
the groove together with the cable.
Please observe the Operating Instructions of the manufacturer when
commissioning the sensors.
Connect the sensors to the controller.
Sensors and limit switches: see ETH catalogue
(solutions.parker.com/ETH_support).
