Mechanical Installation - Festo DFPI- ND2P-E-P-G2 Serie Manual De Instrucciones

The product is tailored to the requirements of the process industry (
www.festo.com/catalogue).
5 Transport and storage
Warning
Danger of crushing! Danger of shearing!
The DFPI can weigh up to about 86 kg, depending on the product version.
Body parts can be crushed or cut off if the product falls.
• For product versions weighing more than 12 kg, always use suitable
load-carrying equipment in order to handle the product safely during
transport and assembly.
Ensure storage conditions as follows:
– Short storage times and cool, dry, shady corrosion-resistant storage locations.
6 Requirements for product use
Installation and commissioning are to be carried out only by qualified personnel in
accordance with the operating instructions.
Note
Improper handling can result in malfunctions.
• Make sure that all the instructions in this chapter are always observed. The
product will then function correctly and safely.
Note
Lateral forces on the piston rod can damage the piston rod bearing of the DFPI.
• Make sure that there are no lateral forces acting on the piston rods, e.g.
through external guiding of the useful load (only guided process valves are
permissible).
Note
Continuous operation at the limits of the specified ambient temperature and
work frequency can reduce the service life of the drive.
• Use lubricated compressed air for continuous operation under extreme
conditions. The oil must be chemically inert (chemically stable) and must not
carbonize.
• Compare the maximum values specified in these operating instructions with
your actual application (e.g. pressures, forces, torques, masses, speeds, tem-
peratures). The product can only be used in compliance with the relevant safety
guidelines if the maximum load limits are observed.
• Ensure that all applicable regulations for your location are adhered to, e.g. of
the trade association or national institutions.
• Remove the packaging except for existing self-adhesive labels on the com-
pressed air supply ports (danger of contamination). The material used in the
packaging has been specifically chosen for its recyclability (exception: oil paper
= residual waste).
• Take into consideration the ambient conditions at the location of use. Corrosive
environments reduce the service life of the product.
• Use the product in its original status, without any unauthorised product modific-
ations.
• Protect the device from fluctuations in pressure and excess operating
temperature. Use control valves for regulating pressure and excess pressure.
• Ensure that the compressed air is properly prepared (
chapter 13).
• Use only unlubricated compressed air under normal conditions. The product has
an initial lubrication which suffices for the complete service life. Using
lubricated compressed air flushes out the initial lubrication. The product may
then only be operated with lubricated compressed air.
• Make sure that cut-off tube ends are cut off square and are free of burrs. This
way you prevent damage to internal O-rings of the DFPI when the compressed
air tubes are inserted.
• Please select the corresponding accessories, e.g. connecting lines and proximity
sensors, from our catalogue (
• Use only proximity sensors approved for the product from our catalogue
( www.festo.com/catalogue).

catalogue 7 Installation
Note
When proximity sensors are used: Ferrous materials (e.g. steel parts and metal
sheets) in the immediate vicinity of proximity sensors can result in accidental
switching signals. When linear drives are installed too close to each other, a
cylinder magnet can trigger switching of the proximity sensor on the neighbour-
ing linear drive.
• During assembly, maintain the required minimum distances from ferrous ma-
terials. The required distances must be determined during mounting for each
specific case!
• When installing more than one linear drive, make sure that the area of effect
of each cylinder magnet does not affect any proximity sensors of neighbouring
linear drives.
If there are high media temperatures in the tubing and in processing valve:
• Use a heat-insulated coupling extension.

7.1 Mechanical installation

For attachment, the linear drive has a mounting hole pattern in accordance with
DIN 3358. Through this, the linear drive is screwed to the process valve or
penstock valve. The mounting orientation is any desired.
• Mount the DFPI with 4 screws.
• Tighten the mounting screws evenly. Tightening torques: with M8 thread 25 Nm
± 5 %; with M10 thread 46 Nm ± 5 %.
The piston rod has a male thread for mounting the slide gate.
The spanner flat at the piston rod is used as a counter holder to avoid impermiss-
ible torques at the piston rod when mounting – spanner size
chapter 13.
• If necessary, use the corresponding adapters for attachment (
www.festo.com/catalogue).

(
during installation:
• Mount the DFPI in such a way that
there are no lateral forces acting on
the piston rod bearings.
• Install the DFPI in such a way that
the required mode of operation for
opening and closing the processing
valve or penstock valve is implemen-
ted.
