4 Function

The product is a non-rotating single-piston drive with bearing guide.

The slide is moved back and forth by alternate pressurisation of the supply ports.

The slide is braked at the end position by shock absorbers.

-For DGSL-...-E/-P/-P1: by external elastic shock absorbers.
- For DGSL-...-Y3/-Y11: with external hydraulic shock absorbers.

9.2 Test run

F a a F

Fig. 9: Positioning payload

1. Position the payload on the slide. Position the centre of gravity of the payload as low as possible.
2. Close the one-way flow control valves.

Technical line drawing of a mechanical assembly with gears and a screw (no text or symbols)

1. Open the one-way flow control valves by one revolution.
2. Pressurise the drive. Slowly pressurise with an on-off valve.

The slide moves to an end position.

1. Start a test run with a moveable mass.

2. Take the following into account in the test run:

3. The speed and the acceleration of the moveable mass

4. The end position
5. The mass of the payload

- The position of the proximity switches

1. Only make changes when the slide is stationary.
2. Unscrew the one-way flow control valves until the required speed of the slide is reached.

i

An increased speed when approaching the end position can result in the slide rebounding from the end position.

1. Fix the proximity switches in the final positioning position.

10 Maintenance

10.1 Replacement of cushioning components

Fig. 10: Cushioning distance s

1. Check the cushioning elements every 2 million cycles.
2. Check the cushioning length s → 12 Technical data
3. Replace the cushioning components if there are signs of wear.
4. Replace the cushioning components after max. 5 million cycles.

10.2 Cleaning

Clean the product with a clean, soft cloth and non-abrasive cleaning agents. For use with reduced particle emission:

- Remove abraded particles and soil from the product:

- Prior to initial commissioning

- Regularly during operation

10.3 Lubrication

i

Note

Check the need for shorter lubrication intervals:

• At high temperatures.
• With excessive dirt accumulation.

• In the vicinity of grease-dissolving liquids or grease-dissolving vapours.

• Lubricate the product as required.

• Lubricate the piston rod and the guide rail.

Use the following lubricant:

Festo LUB-KC1

1. Move the slide by hand for even lubrication.

11 Fault clearance

Fault description Cause Remedy
The slide moves unevenly. The one-way flow control valves are not installed correctly.		Control the exhaust air flow.
The slide is in initial position despite pressurisation.	The tubing is faulty. Check the tubing.
The slide speed is too low. The air volume is insufficient. -Increase the connection cross-sections.-Check the flow control valve setting.-Connect a volume upstream.
The slide stops in the end position without cushioning.	The speed is too high. Reduce the speed.
	The cushioning is too low. -Re-adjust the shock absorber and the (fixed) stop → 9 Commissioning.-Reduce the speed.-Check the shock absorbers and replace if necessary.
	The air cushion is not present. Pressurise both supply ports simultaneously, then exhaust one side.
	The shock absorbers are faulty. Replace the shock absorbers.
	The payload is too large Reduce the payload.
The proximity switches have no function.	The slide has been magnetised. Contact Festo → www.festo.com.
