Electrical Installation; Pneumatic Installation - Festo DFPI-ND2P-C1V-A Serie Manual De Instrucciones

The adjacent illustration shows an
example of the mechanical connec-
Fig. 5 1 ) to a
tion of a DFPI (
Fig. 5 2 ). Ob-
process valve (
serve the following during installa-
tion:
• Mount the DFPI in such a way
that there are no lateral forces
acting on the piston rod bear-
ings.
• Mount the DFPI in such a way
that the required mode of opera-
tion for opening and closing the
process valve or penstock valve
is implemented.
When using additional proximity
sensors:
• Place the proximity sensors in
the corresponding grooves. Cov-
er rails over the grooves fasten
the cables and protect them
against dirt.
• During assembly, maintain the
required minimum distances
from ferrous materials.

7.2 Electrical installation

Warning
• Use only power sources which guarantee reliable electrical isolation of
the operating voltage in accordance with IEC/DIN EN 60204-1. Observe also
the general requirements for PELV power circuits in accordance with IEC/DIN
EN 60204-1.
Note
Installation errors can damage the electronics or cause malfunctions.
• Make sure that the length of the signal line does not exceed the maximum
permissible length of 30 m.
• Connect the earth terminal (Fig. 1 9) to the earth potential with low impe-
dance (short cable with large cross-section) – tightening torque 5 Nm ± 10%.
• Dimension pneumatic lines and electric cables sufficiently.
• Use an electric cable with the following outside diameter:

1. Loosen the mounting screws of the flange receptacle (
and carefully remove the flange receptacle.
2. For DFPI-C1V-A: If necessary, loosen the cable conduit fitting (
For DFPI-C1V-P-A:
3. Route the electric cable through the flange receptacle.
4. If necessary, loosen the socket strip of the electrical connection, which is
fastened with two screws.
5. Use the wire end sleeves suitable for the connection and wire the socket strip
according to the pin allocation (
The integrated positioner is supplied with operating voltage and the setpoint sig-
nal via the following 5-pin plug connector.
Pin Allocation
1 Power supply DC 24 V
2 Input analogue setpoint value 4 ... 20 mA
3 GND Power supply/Input/Output
4 Output analogue actual value 4 ... 20 mA
5 Input initialisation DC 24 V
1) Permissible operating voltage range
2) Reference between position and analogue value is dependent on the initialization (

6. Carefully plug the wired-up socket strip onto the plug connector.
7. Fasten the socket strip with the two screws – tightening torque 0.5 Nm ± 10%.
8. Mount the flange receptacle. When doing so, make sure that the seals are cor-
rectly seated – tightening torque
9. For DFPI-...-...-ND2P-C1V-A:Retighten the cable conduit fitting – tightening
torque see Fig. 8.
For DFPI-...-...-ND2P-C1V-P-A before tightening the cable conduit fitting (accessor-
ies) you first have to perform the pneumatic installation (see section 7.3).

7.3 Pneumatic installation

• Check the necessity of an emergency compressed air supply and of non-return
valves. You will then avoid sudden compensating movements of the piston rod if
there is a drop in pressure and a sudden sliding down of the moving load in a
vertical or inclined mounting position.
• Connect the tubing of the DFPI as follows:
For DFPI-...-...-ND2P-C1V-A
1. If necessary, remove the adhesive labels from the supply ports.
2. Use only suitable threaded connectors – pneumatic connection G¼.
3. Connect the tubing of the DFPI to the compressed air connections (
– Connection P: compressed air supply port for operating pressure
– Connection R: exhaust port
For DFPI-...-...-ND2P-C1V-P-A (protected pneumatic connections)
• Use the connecting cable from the accessories (
Fig. 1). To per-
or standard O.D. tubing pneumatic connecting lines with the following outside
diameter: connection P: 8 mm; connection R: 10 mm
The flange receptacle has two threaded holes (
pre-assembled in the factory (included in scope of delivery).
1. If necessary, loosen the cable conduit fitting (
