Festo Линейный привод с датчиком перемещения DFPI - Manual (Page 4)

8 Commissioning
The product is ready for operation as soon as it is installed and connected.
• Make sure that the operating conditions lie within the permitted ranges (tech-
nical data chapter 13).
• Make sure that a slide gate (process valve) attached to the linear drive can be
positioned without hindrance.
• If necessary, adjust the linear drive adapter attached to the piston rod. This
setting serves to optimise the opening or closing reaction of the connected
process valve or penstock valve.
• Slowly pressurise the linear drive.
For slow start-up pressurisation use soft-start valve type HEL.
• At first, select a slow travel speed.
9 Operation
Warning
Fast moving parts can cause injury to people in the vicinity of the DFPI.
• Make sure that, in the positioning range:
– Nobody can place his/her hand in the path of moving components (e.g. by
providing a protective guard).
– There are no foreign objects in the path of the moving components.
It should not be possible to touch the DFPI until the mass has come to a com-
plete rest.
10 Maintenance and care
If used as intended in the operating instructions, the device will be maintenance-
free.
11 Disassembly and repair
Make sure that the following energy sources are switched off:
– electrical power supply
– compressed air supply.
1. Remove the slide gate from the piston rod.
2. Remove the screws on the flange of the processing valve or penstock valve.
3. Remove the drive (if necessary including mounting adapter and coupling exten-
sion).
Recommendation: Send the product to our repair service. This way, the required
fine tuning and tests will be taken into special consideration.

12 Troubleshooting
Malfunction Possible cause Remedy
Piston rod does not move in
the desired direction Compressed air tubes inter-
changed Correct the tubing connection
Displacement encoder cable
incorrectly connected at posi-
tioning controller or DFPI (e.g.
connections at pin 1 and pin 3
interchanged). Correct the connection
