6 Commissioning
Before each commissioning and in operation:
Warning
Moving masses can cause personal injury and
material damage (risk of crushing).
• Make sure that, in the path of the moving
components
– nobody can place his/her hand
(e.g. through a protective guard),
– there are no foreign objects.
It should not be possible to touch the DGC-HD
until the load has come to complete rest.

At medium or large useful loads or high speeds:
• Use the sizing software “DGC-QuickCalc” for pneumatic drives in the support portal
( www.festo.com/sp).
• Make sure that cushioning devices are of sufficient size.
Without external cushioning devices the DGC-HD will withstand maximum speeds and useful loads
in accordance with catalogue specifications or table ( 11 Technical data).
Even in the event of malfunctions, the limit values must not be exceeded.
Carrying out commissioning
• Slowly pressurise the system as a whole.
In this way you will prevent sudden uncontrolled movements.
For slow start-up pressurisation, use start-up valve type HEL.
1. Close the one-way flow control valves
– for both sides at first completely
– then one turn open again.
2. Pressurize the DGC-HD as follows:
– At first on both sides simultaneously. The slide will then
move slightly to a centre of equilibrium.
– Then exhaust the DGC-HD on one side. In this way you can
avoid peak loadings on the DGC-HD and in the compressed
air network.

3. Start a test run.
4. Check whether the speed of the slide has to be modified.
5. Open up the one-way flow control valves slowly until the desired slide speed is reached.
As intended, the slide should reach the end position without striking hard against it or bouncing
back.
