2 Function and application
The stop lever 1of the intermediate-position module aJ swivels in and out when
the pneumatic connections are pressurized. In the swiveled-out status, the cush
ioning component in the shock absorber retainer 9advances to the stop lever.
The slide of the linear drive 8is therefore in an intermediate position. The posi
tion of the stop lever 1can be sensed through cylinder switches in the slots 6.
The intermediate position module DADM-EP-G6 aJ is intended to be used as an
external stop for a linear drive and enables the slide to be placed in an
intermediate position within the stroke range. The DADM-EP-G6 may only be used
in combination with sufficient cushioning. When combined with linear drive DGSL,
the shock absorber retainer DADP-ES-G6 9with cushioning component is suitable
(èwww.festo.com/catalogue).
3 Requirements for product use
 Take into consideration the legal regulations applicable for the destination as
well as:
– regulations and standards,
– regulations of the testing organisations and insurers,
– national specifications.
 Take into account the material specifications (èTechnical data).
 Use the product in its original status, without any unauthorised product modific
ations.
 Take into consideration the ambient conditions at the location of use.
Corrosive environments (e.g. ozone) will reduce the service life of the product.
 Use the product in a clean environment.
In case of contamination, the lever may swivel sluggishly.
 Take the tolerance of the tightening torques into account. Unless otherwise
specified, the tolerance is ± 20 %.
 Make sure the compressed air is properly prepared (èTechnical data).
4 Installation
4.1 Mechanical installation
Note
Danger of damage to the linear drive.
 Always operate the intermediate-position module aJ in combination with the
shock absorber retainer 9with a screwed-in cushioning component
(èwww.festo.com/catalogue).
 Make sure that the slide of the linear drive moves cushioned into the interme
diate position and end positions. In combination with linear drive DGSL, the
intermediate-position module must be fastened directly next to the linear
drive.
 Observe that the intermediate-position module aJ projects over the contour
of the linear drive DGSL 8.
To mount the intermediate-position module aJ:
 Fasten the intermediate-position module with two screws and the accompany
ing centring sleeves to the mounting surface (flatness: Min. 0.1 mm). This
roughly establishes the position of the intermediate position. Precision adjust
ment of the intermediate position takes place during commissioning by screwing
the cushioning component in or out.
The following mounting options are possible:
– lateral mounting to the drill holes 4
– mounting to the base 7.
Observe the tightening torque (èFig. 3).
 Fasten the shock absorber retainer 9with two screws to the slide of the linear
drive.
Comply with the tightening torque (èFig. 4).

Seal unused connections with
blanking plugs.

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.
