Hello folks, I’ve been working DMG machine many years.
So far as the control keys please see the 2nd chapter of your Operator Manual for complete description, also to explain the I, II, III, IIII mode buttons under key slot. The two should not be confused on operation.
Nevertheless, the key I is new operator, III for trained operator. “Master” Key IIII is for clearing all but 2000 time compliance inspections and on CELOS for setting up Ethernet connection to your company network.
There is an “Inspection” key available issued only after attending DMG MORI Inspection course. The coveted “SERVICE” key is DMG MORI engineers ONLY.
To those that always want the highest level access, read up on latest safety reports where people are seriously injured or killed by bypassing safety or access locks.
Feel free to contact me for any DMG related service issue.
