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 precision adjustment of the end positions:
1. Loosen clamping component aE.
2. Position the slide by hand in the desired
end position.
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 (

shock absorber spins. The max. torque is summarised in the following table (

Note
The exact slide position must be checked during a test run with compressed air
applied and, if necessary, corrected.

6.2 Carrying out commissioning
DGSL-...-P
Before each commissioning and in operation:
Warning
DGSL-...-P1
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
DGSL-...-Y3
guard).
DGSL-...-Y11
– There are no foreign objects (e.g. hexagon
wrench when setting the end position under pres-
sure).

Place your effective load on the slide of the

• Turn both upstream one-way flow control valves

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 pressurisation, use start-up valve type HEL.
The slide moves into an end position.
1)
2. Start 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 acceleration 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 (
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.

If the slide can be heard to strike hard:
3.5
5. Interrupt the test run.
Causes of hard knocking may be:
– the moveable mass is too high
– the slide speed is too high
13
– 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:
