1 Function and application
The stop lever 1 of the intermediate position module
swivels in and out when the pneumatic connections are
pressurized. When swivelled out the shock absorber on
the slide of linear drive DGC(I) moves onto the stop lever.
The slide is therefore in an intermediate position.
The position of the stop lever (swivelled in or out) can be
scanned by means of proximity switches in the grooves 3
of the intermediate position module. The intermediate
position module DADM-DGC enables the slide to be
placed in an intermediate position within the stroke
range. After conversion the intermediate position module
can be used for both impact directions.
The intermediate position module DADM-DGC has been
designed for use on linear drives DGC(I)-...-KF 9. It may
only be used in conjunction with shock absorber support
DADP-DGC 8 and a stop KYC 7 behind the intermediate
position module.
2 Conditions of use
• Compare the maximum values specified in these oper-
ating instructions with your actual application (e.g.
forces, torques, temperatures).
The product can only be operated in accordance with
the relevant safety guidelines if the maximum loading
limits are observed.
• Take into consideration the ambient conditions at the
location of use.
Corrosive elements in the environment (eg. ozone) will
reduce the service life of the product.
• Please operate the DADM-DGC in a clean environment.
If dirt is not removed, the lever may only swivel with
difficulty.
• Please comply with national and local safety laws and
regulations.
• Use the product in its original state. Unauthorised
modification is not permitted.
• Remove all transport packing such as foils, caps,
cardboard.
It is intended that the packaging be recycled on the
basis of its constituent materials (exception: oiled
paper = other waste).

There is a danger of linear drive DGC(I) being damaged:
• Always operate the intermediate position module
DADM-DGC in conjunction with the shock absorber
support DADP-DGC with screwed-in original shock
absorbers, stop sleeves and spacing plates.
• Make sure that the slide of the DGC(I) with the shock
absorber in the support 8 moves cushioned into the
intermediate position and the end positions:
- against the intermediate position module or
- against the stop 7 KYC
• When fitting the linear drive, take into account the
fact that the intermediate position module DADM-
DGC projects over the contour of the DGC(I)
Reversing the direction of impact of the DADM-DGC (turn-
ing the support brackets 4):
1.First unscrew completely all threaded pins 2 and re-
move the pressure pins aJ thereunder (turn the DADM-
DGC and let the pressure pins fall into your hand).

pull them off.

3.Rotate the support brackets 180°.
4.Fit the support brackets again. In order to do this you
must press down the black cap aA.
5.Push the pressure pins aJ into the appropriate
threaded holes.
6.Screw all the threaded pins 2 into the holes until the
pressure pins touch the support brackets.

If the gap between the stop lever and the shock
absorber is too small, this may result in malfunctioning.
• Make sure that the minimum distance X 1 between
the impact surface and the shock absorber head is
observed in order that the stop lever can be
swivelled in (see following diagram).
• Swing the intermediate position module onto the dove
tail aB on the linear drive 9.
• Shift the intermediate position module into the desired
position.
• Tighten all threaded pins 2 at first by hand.
This will ensure equal clamping.
• Then tighten the threaded pins.
The tightening torque is M 1 .
• Lock the threaded pins with a screw locking medium.

Electrical installation
Interrogating the stop lever positions
• Use proximity switches with longitudinal cable exit in
accordance with the chapter ”Accessories.”
• Place the proximity switches in the grooves 3 of the
intermediate position module.
• Fasten the proximity switch in the end position to be
scanned.
Make sure here that there is a gap of minimum 10 mm
from ferromagnetic parts.

The stop lever can damage the head of the shock
absorber when it moves back.
• Make sure that the slide of the linear drive is outside
the swivel range when the stop lever moves in (e. g.
by means of a control delay circuit).
The swivel-in speed of the stop lever exceeds the
slide speed of the linear drive DGC(I).
4 Commissioning
Please note . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Malfunctioning can occur if excessive loads are applied
to the stop lever.
• Make sure that the following points are always
observed:
– the alignment of the stop in accordance with the
following diagram (the stop lever must not be
“overrun”)
– there must be sufficient room for the stop lever
to swivel in and out (permitted gap X 1 see chapter
“Fitting mechanical components”)
– the stop lever must be moved out at the correct
time
– the shock absorber of the linear drive must be
outside the stop lever swivel range.

Be careful not to squash your fingers when the stop
lever moves in.
• 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.
• Complete the commissioning as described in the oper-
ating instructions DGC(I) as follows:
1.Push the slide of the linear drive by hand into the end
position from which movement is to be made to the
intermediate position.
2.Slowly pressurize an end position of the stop lever on
the intermediate position module.
3.Pressurize the linear drive so that the end position
reached under point 2 is retained.
4.Start a test run in accordance with the operating
instructions for the linear drive at low frequency and at
low impact speed.
5.Accelerate the work load on the DGC(I) in stages, until
the final operating speed is reached (note the limits of
use in the m/v diagrams in the operating instructions
DGC(I)).
The slide of the linear drive must not strike hard against
the intermediate position module.
6.If necessary, adjust the end position as follows:
– Loosen the locking nut aD
– Turn the stop screw aE into the desired position
with the hexagon socket wrench.
The maximum adjustable end position range is L.
– Tighten the locking nut aD (counterhold with
hexagon socket wrench).
The tightening torque for the locking nut is M
3 .
7.Conclude the test run.
