3.2 Pneumatic installation

Connecting the tubing for the clamping cartridge2/clamping unit5:
1. Remove the mounting screw9 on
the supply port 1 of the clamping
cartridge2.
2. Insert a push-in fitting
(M5 DIN 912 or GÁ) into the sup-
ply port 1 of the clamping cart-
ridge2.
The tightening torque is 0.5 Nm.
Connecting the tubing of the cylinder 8:
• Connect the tubing of the clamping cartridge2 and the cylinder8 with the direc-
tional control valves intended for this purpose.
The following shows two examples of control circuits.

pressure failure

Warning
Clamping rods can move out suddenly and
unexpectedly, thereby causing injury to
anybody who is in the positioning range.
• Make sure that:
– nobody reaches into the positioning
range of the moveable load
– no objects project into the danger
zone of the moving load
– the clamping cartridge2 is logically controlled in a correct manner
– no modifications may be made to the product.
Improper modifications impair the functioning and represent a safety risk.
Note
Clamping in movement sequences (braking) is not permitted. Increased wear
leading to complete failure is possible.
• Make sure that the dynamic holding force is always less than the static holding
force.
Apart from that, the clamping rod can break through.
• Make sure that the cylinder8 is only pressurised in the park position when the
clamp is released.
Movement against a non-pressurised chamber will create an acceleration
which can damage the cylinder8.
1. Slowly pressurise the complete system with at least 3 bar.
2. Exhaust the cylinder8.
3. Completely screw in the adjusting screws on the cylinder8 for the end-position
cushioning6.
4. Start a test run as described in table Fig. 15.
5. End the test run.

5 Operation
The clamping rod4 can only be moved if the clamping cartridge2 is pressurised
or if the mounting screw9 is screwed in.
Note
Transverse loadings due to non-aligned guides lead to increased wear.
• Make sure the clamping rod4 is only loaded in the direction of movement.
• Use a self-aligning rod coupler (
forces.
5.1 Clamping during operation
1. Pressurise the supply port of the park position on the cylinder8.
2. Exhaust the clamping cartridge2 and then the cylinder8.
5.2 Moving out of a clamped parking position

1. Pressurise the supply port1 on the
clamping cartridge2 with 3 to
max. 10 bar.
2. Move the clamping rod4 into the
desired position.

5.3 Checking the clamping function of a cylinder with clamping unit8:
• Check the clamping function on a regular basis and immediately after a sud-
den pressure failure. The piston rod should be located in a park position
when doing this.
Positioning the piston rod:
1. Pressurise the supply ports on the cylinder8 on both sides.
2. Release the clamping function of the clamping cartridge2 manually or pneu-
matically.
3. Exhaust one of the supply ports on the cylinder8 and, in doing so, move the
piston rod4 to a park position.
Checking to ensure a safe clamping function without an effective load:
1. Pressurise the cylinder8 on the stroke side chamber so that the piston rod4 is
held securely in the park position.
2. Exhaust the clamping cartridge2 to clamp the piston rod4.
3. Pressurise the cylinder8 in the stroke direction.
Note
• Make sure that the maximum holding force of the clamping cartridge2 is not
exceeded with the cylinder pressure.
The clamping function of the clamping cartridge2 is fine if the piston rod4 only
moves slightly ( axial play in the chapter "Technical data").
6 Maintenance and care
Cleaning:
1. Exhaust the cylinder8 and the clamping cartridge2.
2. Clean the clamping unit and the clamping rod4 with a soft cloth.
Avoiding unlubricated operation:
3. Lubricate the surface of the clamping rod4 with a thin layer of grease.
• Use lubricating grease LUB-KC1 SILIKONFREI. The lubricating grease should
only be recognisable by a slight darkening of the surface due to the colour of
the grease.
• Recommendation: Apply the grease with a cloth or soft brush.
Cylinder with clamping unit8
Pressurise both ports of the cylinder8 slowly in
order to prevent danger caused by the piston rod4
accelerating suddenly.
Adjust the pneumatic end-position cushioning by
means of the adjusting screws (not on cylinders with
elastomer cushioning).
Accessories) in order to avoid transverse
Cylinder with clamping unit8
1. Pressurise the piston of the cylin-
der8 on both sides.
2. Pressurise the supply port1 on the
clamping cartridge2 with 3 to
max. 10 bar.
3. Switch the directional control valve
for controlling the cylinder8.
