Maintain the support clearance of 300 mm when attaching transportation£

equipment.

Assembly

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.

–

Mount the product on a mounting surface with a flatness of 0.05% of the stroke

length, but max. 0.1 mm.

–If necessary: select the mounting components or the accessories. The centring

sleeves are not included in the scope of delivery.

To prevent collisions: mount the mounting components outside the positioning

range.

7.2 Mounting mini slide

7.4

Mounting the proximity switches

For position sensing with proximity switches:

Fig. 3:

Position sensing

Slide the proximity switches into the slots

Fig. 3.

Avoid external influence caused by magnetic or ferritic parts in the vicinity of

the proximity switches. Check the required clearance for the specific applica-

tion.

To prevent contamination: use slot covers on all unused slots

www.festo.com/catalogue.

7.5 Mounting one-way flow control valves

To set the velocity:

• Use one-way flow control valves in the supply ports. They are screwed directly

into the supply ports.

To secure the payload from dropping if the pressure fails:

• Use check valves.

8 Commissioning

8.1 Preparation

NOTICE

Unexpected movement of components.

• Keep foreign objects out of the positioning range.

• Initiate start-up at low speed.

• Slowly pressurise the complete system. Use the on-off valve HEL for slow

start-up pressurisation.

With medium or large payloads or at high speeds:

•

Use the sufficiently dimensioned arrester fixtures.

Without the use of external arrester fixtures, the product will withstand the

maximum speeds and payloads defined in the catalogue or the technical

data.

8.2

Adjustment of slide end positions

In the factory settings for the mini slide DGST-...-P/-Y12 the minimum distance L

of the shock absorbers specified below for the slide end positions must be

observed.

Fig. 4:

Adjustment of the slide end positions

1. Loosen the threaded sleeves.

Position the slides one after the other at the retracted and advanced end

positions.

3. At the end position: screw in the shock absorber to the end position. Do not

exceed the maximum torque when screwing the internal hexagon socket/slot.

Maintain the minimum distance L. If the minimum distance L is not long

enough, the shock absorbers will not be completely effective and the product

will impact internally. This can lead to the destruction of the product.
