Electric installation
2.2.1.
Sensors
All electro cylinders feature a permanent magnet in the spindle nut. It activates the limit
switches which are mounted in the special mounting grooves on one side of the cylinder.
Sensors and limit switches: see from page 28 in the catalog section (following the mounting
instructions).
2.2.2.
Sensor mounting
◆
Sensors can be inserted in 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 pointed screwdriver to lever the ends of the covers off
the grooves. Pull the entire cover out manually.
◆
Install the magnetic cylinder sensors. The sensors can be inserted into the grooves from
above. The cable ends should lead into the drive 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 on page 18), 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 with the aid
of a pair of scissors. Please cut off an additional
5 to 10 mm, where the cables are to be lead out
of the profile.
◆
Insert the cables into the grooves of the plastic covers and push the cover into the groove
together with the cable.
◆
Connect the sensors to the controller.
Sensors and limit switches: see from page 28 in the catalog section (following the
mounting instructions).
Sensor mounting example: 2 end limits with machine zero
