4Function
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.
The shock absorbers can also adjust the stroke.

7Assembly
7.1 Preparation
–Position the product to ensure that the operating elements are accessible,
e.g. the clamping components for the shock absorbers.
–Mount the product without torsional stresses.
–If necessary: select the mounting components or the accessories.
To prevent collisions: mount the mounting components outside the positioning
range.
7.2 Mounting
1. Select a suitable adapter plate.
2. To make the through-holes accessible, move the slide to the retracted end
position.
3. Use the included centring sleeves.
4. Mount the product according to the type of mounting according to stroke.

Slots for proximity switches
1. Position the proximity switches in the slots [1].
Use the lower slot for the DGSL-...-4 and DGSL-...-8 products.
2. Temporarily lock the proximity switch.
3. After the test run, mount the proximity switch in the suitable position.
8.2 Rough setting of end positions
1. Position the slide at the desired end position by hand. Leave the slide in the
retracted end position during the setting procedure.
2. Unscrew the retaining screws of the (fixed) stop 1 and the orifice 2.
–Certain product variants allow coarse adjustment of the front-end position
è www.festo.com/catalogue.
–A stroke reduction of max. 2 standard strokes is possible in combination
with the precision adjustment.
3. Replace the (fixed) stop 1 with the orifice 2.

1. Use one-way flow control valves to set the speed of the slide.
L-shaped flow control valves on the front air port permit unhindered access
for adjusting the cushioning with sizes DGSL-...-4 and DGSL-...-6.
2. Remove the transport covers on the supply ports.
3. Connect tubing to supply ports:
–retract movement 1
–advance movement 2

4. The connecting threads must be sealed. The 3 and 4 alternative connec-
tions are pre-assembled on the DGSL. The alternative connections are sealed
with blanking plugs.

9.2 Test run
Fig. 10: 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.
3. Open the one-way flow control valves by one revolution.
4. Pressurise the drive. Slowly pressurise with an on-off valve.
ÄThe slide moves to an end position.
5. Start a test run with a moveable mass.
Take the following into account in the test run:
–The speed and the acceleration of the moveable mass
–The end position
–The mass of the payload
–The position of the proximity switches
7. Only make changes when the slide is stationary.
8. Unscrew the one-way flow control valves until the required speed of the slide
is reached.
An increased speed when approaching the end position can result in the slide
rebounding from the end position.
9. Fix the proximity switches in the final positioning position.
10 Maintenance
10.1 Replacement of cushioning components
Fig. 11: Cushioning distance s
1. Check the cushioning elements every 2 million cycles.
2. Check the cushioning length s è 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 soft cloth. Do not use aggressive 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
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.
1. Lubricate the product as required.
2. Lubricate the piston rod and the guide rail.
Use the following lubricant:
–Festo LUB-KC1
3. Move the slide by hand for even lubrication.
11 Malfunctions
11.1 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 posi-
tion without cushioning.
The speed is too high. Reduce the speed.
The cushioning is too low. –Re-adjust the shock absorber
and the (fixed) stop è 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.
