Festo DFPI-ND2P-C1V-A Serie Manual De Instrucciones página 10

After the compressed air supply is switched on, the drive travels as follows:
– The drive moves to the safety position if the operating voltage supply or the
analogue setpoint are outside the permissible range.
– The drive moves to the specified analogue setpoint position if the operating
voltage supply is in the permissible range, depending on the end positions
taught during initialization.
Switching the DFPI off
• Switch the power supplies off in the following sequence to ensure safe venting
of the integrated valve manifold:
1. First switch off the operating voltage supply.
2. Only after that switch off the compressed air supply.
Only when the drive is vented can the piston rod be shifted manually, for example
to push the piston rod in for safe transport.
10 Maintenance and care
If used as intended in the operating instructions, the device will be free of mainten-
ance.
11 Disassembly and repair
Warning
Danger of crushing! Uncontrolled advance of piston rod.
When the power supplies are switched off, if the compressed air supply is
switched off first and only after that the operating voltage supply, in case of error
(e.g. defective valve manifold) there may be continuous excess pressure in a
cylinder chamber. During dismantling the linear drive can then advance unexpec-
tedly, thus crushing people's body parts.
• Switch the energy supplies off in the following sequence to allow the in-
tegrated valve manifold to vent the drive:
1. First switch off the operating voltage supply.
2. Only after that, switch off the compressed air supply.
Warning
Danger from parts flying through the air!
If there is still excess pressure in a cylinder chamber despite the compressed air
supply being switched off, when a cylinder end cap is loosened it can tear off, fly
through the air and injure people.
• Do Not dismantle cylinder end cap! The product may be overhauled only by
our repair service.
Disassembly
1. First switch the operating voltage supply off and then the compressed air supply
to allow the integrated valve manifold to vent the drive.
2. Remove the slide gate from the piston rod.
3. Remove the screws on the flange of the process valve or penstock valve.
4. Remove the drive (if necessary including mounting adapter and coupling exten-
sion).
Repair
• Make sure that the product is overhauled only by our repair service. This way
the fine tuning and tests that are required will be taken into particular con-
sideration.
