2 Function and application
When the compressed air ports are pressurized alternately, the piston moves back-
wards and forwards in the tubing. By means of a rigid connection, the outer slide
also moves. The slot in the cylinder barrel required for this is covered by a band
system.
This product has been designed for transporting mass loads.
Pressureless movement of the slide is only approved when eliminating faults and
at a low speed. If excessive speed is used, the vacuum which results can pull the
sealing band into the piston chamber. This can lead to:
– high leakage and
– non-permitted acceleration (e. g. when installed vertically).
The following distinctions are made:
– as cylinder:
In normal operation the slide traverses the complete stroke from one end
position to the other.
– as servopneumatic positioning axis:
When controlled by a controller, the slide can move to any intermediate position
in normal operation.
Using the DGP(L) as a servopneumatic positioning axis:
Note
• Omit the sections which are marked "Only cylinder". Otherwise positioning
problems will occur.
• Observe the instructions in the manuals for the positioning controller used
English
(e.g. SPC11/SPC200).
3 Transport and storage
• Consider the weight of the DGP(L).
Depending on the design, the DGP(L) can weigh over 80 kg.
4 Requirements for product use
6
Note
Malfunctions will occur if the device is incorrectly used.
• Be sure to always comply with the specifications in this chapter.
• Note the warnings and instructions on the product and in the relevant operat-
ing instructions.
• Compare the maximum values specified in these operating instructions with
your actual application (e.g. forces, torques, temperatures, masses).
Only compliance with the load limits allows operation of the product in
compliance with the relevant safety regulations.

• Take into consideration the ambient conditions at the location of use.
Corrosive elements in the environment (e.g. ozone) will reduce the service life of
the product.
• Please comply with national and local safety laws and regulations.
• Use the product in its original condition without any unauthorised modifica-
tions.
• Remove all transport packing such as foils, caps, cardboard.
Exception: adhesive labels on compressed air ports (danger of dirt entering the
tubing)
The packing is intended for recycling (except for: oiled paper = other waste).
• Leave the blue plastic cover caps fitted on the end caps. These protect the
clamping device of the band system from external influences.
• Ensure that the compressed air is properly prepared
• Take the tolerance of the tightening torques into account. Unless otherwise
specified, the tolerance is ±20 %.
5 Installation

5.1 Mechanical installation

• Avoid damaging the band system.
Damage to the band system can cause leakage and reduce the efficiency of the
DGP(L).
• Avoid the sealing band being pressed and/or sucked in.
Damage to the sealing band reduces operational reliability. Sudden movement
of the unpressurised slide can create a vacuum which sucks the sealing band
into the piston chamber.
• Leave all screws and threaded bolts in their original states, unless you are
requested to modify them in these instructions.
• Make sure that the device is fitted free of mechanical stress and distortion.
• Use the central support (profile mounting) MUP with the following gaps
between supports (l) (
