6 Commissioning

6.1 Preparing for commissioning

Note

• Make sure that the following conditions

are observed:

– The distance L of the cushioning com-

ponent must be maintained at a min-

imum (factory setting)

( Fig. 16 and Fig. 17).

Falling below the factory settings

destroys the guide.

– For all setting work, all threads of the

cushioning component are constantly

being manipulated.

For pre cision adjustment of the end positions:

1. Loosen clamping component aE.

2. Position th e slide by hand in the desired

end position.

Fig. 18

3. Turn the cushioning component 1 with a

hexagon wrench until the end position is

reached ( Fig. 20).

The max . torque must be observed thereby

( Fig. 21).

4. Retighten the clamping component with

the following tightening torque ( Fig. 21).

The rubber buffer touches the

slide.

The stop sleeve touches th e

slide (against the force of the

cushioning)

The shock absorber housing/

reducing sleeve

(for DGSL-…-Y11) touches the

slide (against the force of the

shock absorber)

1) If the max. torque for the internal hexagon socket at the DGSL-…-Y3 is fallen below, the hexagon in the

shock absorber spins. The max. torque is summarised in the following table ( Fig. 21).

Note

The exact slide position must be checked during a test run with compressed air

applied and, if necessary, c orrected.

6.2 Carrying out commissioning

Before each commissioning and in operation:

Warning

Make sure that in the travel range of the drive

– Nobody can reach into the path of the movable

components (e.g. by providing a protective

guard).

– There are no foreign objects (e.g. hexagon

wrench when setting the end position under pres-

sure).

Fig. 22

•

DGSL so that the break-down torque of the

dynamic force F and the lever arm a remains

small.

Fig. 23

• Turn both upstream one-way flow control valves

– at first completely closed

– then one rotation open again

Fig. 24

Note

• Make sure that the operating conditions lie within the permissible ranges.

1. Pressurize the drive as follows:

– Pressurize the drive by slowly pressurizing one side.

For slow start-up pre ssurisation, use start-up valve type HEL.

The slide moves into an end position.

2. Star t a test run with the moveable mass.

3. During the test run check whether the following points need to be modified:

– the speed and the ac c eleration of the moveable mass

– the end position

– the mass of the effective load

– the position of the proximity sensors.

If this is the case, the modifications must be carried out only when the slide is at

rest.

4. Open up the one-way flow control valves slowly

until the desired slide speed is reached.

The maximum permissible speed must not be

exceeded here ( 12 Technical data).

The slide should reach the end position safely, but

not strike hard against it.

Too hard of an impact will cause the slide to re-

bound out of the end position.

Fig. 25

If the slide can be heard to strike hard:

5. Interrupt the test run.

Causes of hard knocking may be:

– the moveable mass is too high

– the slide speed is too high

– no compressed air cushion on the exhaust side

– cushioning not sufficient (can be set for DGSL-…-P1).

6. Make sure you remedy the above-mentioned causes.

7. Repeat the test run.

When all necessary corrections have been undertaken:

8. End the test run.

9. Fasten the proximity switches in their final positions.
