4.3 Electrical installation
For sensing the stop lever positions:
Use proximity switches with
longitudinal cable exit in accordance
with the our catalogue
(èwww.festo.com/catalogue).
Place the cylinder switches in the
slots 6of the intermediate-position
module.

Fasten the cylinder switches in the end positions to be sensed.
Make sure here that there is a gap of minimum 10 mm from ferromagnetic parts.
5 Commissioning
Warning
Fingers can be pinched when the stop lever retracts.
Make sure that nobody can place his/her hand in the positioning range of the
stop lever and that there are no objects in its path.
Note
Malfunctioning can occur if excessive loads are applied to the stop lever.
Make sure that the following points are always observed:
– the stop lever must be retracted/advanced at the correct time
– briefly switch off pressure to the linear drive for retracting the stop lever or
pressurize on both sides.
Complete the commissioning, observing the notes in the operating instructions
as follows:
1. Push the slide of the linear drive by hand into the end position from which move
ment is to be made to the intermediate position.
2. Pressurize the linear drive such that the end position approached under point 1
is maintained.
3. Pressurize the port 3on the intermediate position module to extend the stop
lever. The stop lever extends.
4. Start a test run in accordance with the operating instructions for the linear drive
at low cycle rate and at low impact speed.
5. Accelerate the payload at the drive in steps until the later operating speed is
reached.
The slide of the linear drive must not strike hard against the intermediate-posi
tion module.
6. If required, adjust the intermediate position by screwing the cushioning com
ponent in or out at the shock absorber retainer DADP-ES-G6 9.
Maintain the unscrewing length X and the permissible tightening torque of the
lock nut (A) (èFig. 9).
7. Terminate the test run.
