I got a problem with my recently bought Deckel DMU 50T -04 that use Millplus V520.

I ran the M67 from the MDI meny and opened the tool magazine. It worked fine but when closing the magazine again I had to little air pressure so it did not work. Now I only get the E523 message and can do nothing! The maginze is still open and I tried to restart the computer but that made things worse. Now I have to run the reference points again but can not due to the open magazine. What to do??
