Checking the System for Leaks
The vacuum area gripper must be ready for operation in order to check the system for leaks. Close the
separating 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 vacuum level of the vacuum generator
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.
