Checking the System for Leaks
8.11
The area gripper must be ready for operation in order to check the system for leaks. Close the separat-
ing cylinder and switch on the vacuum generator. The vacuum level can now be read at the gauge. The
measured value should be up to 10% lower than the maximum reachable vacuum of the vacuum gen-
erator used.
Example: The vacuum generator reaches a maximum of
–0.5 bar
A vacuum of at least
–0.45 bar
must be displayed on the gauge.
If the vacuum is not achieved, the system must be checked for leakage as follows.
1. Check the hose, hose connections, tubing and the cable screw union on the multi-pole plug for
damage and leaks, and replace them as necessary.
2. Check that all the sections and all other functional components are properly assembled.
3. Check that the spacer sleeves are still in place between the valve plate and base section.
4. Check whether the vacuum filter is blocked or dirty; if necessary, clean the filter cartridge or re-
place it.
5. Check the seals on the covers and separating cylinder and replace if necessary.
6. Check that the vacuum generator is fully functional.
