Commissioning
Before each commissioning and in operation:
WARNING!
Payloads can cause personal injury and material damage (risk of crushing).
•
Make sure that, in the travel range:
–
Nobody can place his/her hand in the path of moving components (e.g. by providing a pro-
tective guard).
–
There are no foreign objects in the path of the moving components.
It should not be possible to grasp the DGC-HD until the load has come to a complete rest.
With medium or large payloads and/or at high speeds:
–
Use the engineering software "DGC-QuickCalc" for pneumatic drives in the support portal
(
è
–
Use sufficiently large arrester fixtures.
Without external arrester fixtures, the DGC-HD will tolerate the maximum speeds and payloads set
out in the catalogue specifications or table (
è
The limit values may not be exceeded, even during malfunctions.
Commissioning – processing
–
Slowly pressurise the system as a whole.
In this way you will prevent sudden uncontrolled movements.
For slow start-up pressurisation, use on-off valve HEL.
1. Close the one-way flow control valves
–
for both sides initially, and
–
then open again one turn.
Fig. 10
2. Pressurise the DGC-HD as follows:
–
Initially simultaneously at both sides. This causes the slide to move slightly to a point of bal-
ance.
–
Then exhaust the DGC-HD on just one side. This prevents peak loads on the DGC-HD and in
the compressed air system.
3. Start a test run.
