2 Function and application

By applying compressed air to the connec

tions alternately, the inner slide moves back

wards and forwards in the cylinder barrel.

By means of a fixed connection, the outer

slide also moves. A band system seals the

required slot in the cylinder barrel.

The component is designed for space-saving

mass transport only in slide mode.

The pressureless movement of the slide is

only permitted for rectifying faults and at low

speed.

If the speed is too high, the resulting low

pressure can pull the sealing band into the

piston chamber. This can lead to:

– excessive leakage and

– non-permitted accelerations (e.g. if fitted in a vertical position).

3 Conditions of use

Please note

Incorrect handling can lead to malfunctioning.

SMake sure that the points mentioned in this chapter are always observed.

The product will then function correctly and reliably.

SCompare the limits in these operating instructions with your current applica

tion (e.g. pressures, forces, torques, masses, temperatures, speeds).

Only when the load limits are observed can the component function in accord

ance with the relevant safety guidelines.

SConsider the ambient conditions at the location.

SPlease observe the regulations applicable to your location (e.g. local or

national authorities).

SRemove all packaging.

The packing material can be recycled (except for oiled paper = waste).

SEnsure that there is a supply of compressed air which is:

– correctly prepared,

– dried,

– non-lubricated.

Only if non-lubricated air is maintained, will lubrication be guaranteed for the

complete service life of the product.

SSlowly pressurize the complete system.

Movements of the actuators will then be under control, even in unintentional

situations.

SUse the product in its original condition without undertaking any modifica

tions.

4 Transport and storage

SAlways store the component in a lying or

vertical standing position.

Otherwise the component will become

distorted especially with long strokes.

5 Fitting

Mechanical fitting

SPrevent the sealing band from being

pressed or sucked in.

Damage to the sealing band reduces the

operating reliability.

A sudden jerk movement of the pressure

less slide can create a low pressure which sucks the sealing band into the

piston chamber.

SPlace the component in position with re

gard to the following points:

– You must be able to gain access to the

operating parts and connections later

when the component is installed.

– The fitting position takes into account

the minimum distances required for

reliable operation of the proximity

switches used.

SPlace the work load on the slide as fol

lows:

– The tilting torque of force F parallel to

the cylinder axis and distance a should

remain as small as possible.

– Mass moments of interia occurring in a

dynamic application should be calcu

lated, especially with changing loads.

SSelect the screw for fastening the work

load with maximum screwing depth as in

Pneumatic fitting

To set the slide speed:

SUse one-way flow control valves of type GRLA-...

These valves control the exhaust directly

in the compressed air connections.

For screwing in directly without one-way flow

control valves:

SUse barbed fittings or screw connections

with small width across flats.

Fittings with large width across flats re

quire too much space for rubing.

SCheck whether non-return valves with

triggering type HGL-... are required.

If there is a loss of pressure in cases

where the cylinder is fitted in a vertical

position, non-return valves ensure that

the mass remains in the position reached.

SSelect the compressed air connections for

your application:

There are alternative compressed air con

nections (B) to the connections intended

for use (A) when supplied from the fac

tory.

These are sealed with threaded pins.

On the alternative connections, the

threaded pins will only seal when new

sealing medium is applied.

SConnect the SLG-... to the compressed air

connections 2.

The assignment of the connecting holes to

the direction of travel of the slide is shown

in Fig. 16.

Electrical fitting

When using proximity switches:

Please note

SMake sure that the minimum distances from other proximity switches corre

spond to the values specified in the diagram.

In this way you will avoid incorrect switching. If the minimum distances are

not observed, an individual functional check may be necessary.

In this way the proximity switches are

6 Commissioning

Complete system

SSlowly pressurize the complete system.

Movements of the actuators will then be

under control, even in unintentional situ

ations.

Use the start-up valve type HEL-... for this

purpose.

Individual unit

Please note

As a result of possible faults in the struc

ture or in the controller, the component will

not react as expected under certain circum

stances.

SMake sure that:

– nobody can reach into the positioning

range of the moving mass (e.g. by

means of a protective screen)

– foreign objects do not enter the

positioning range of the moving

mass.

Warning

Uncushioned movements in the end posi

tions impede the functional reliability of

the component.

SMake sure that the fixed stops do not

project above the housing contour of the

component.

Otherwise the stops will not have suffi

cient cushioning effect. The inner slide

will strike against the cover.
