I also include a IR camera scan on the running press and a Profibus analyzation on the circuit.
The primary goal of maintenance is to avoid or mitigate the consequences of failure of equipment. This may be by preventing the failure before it actually occurs which Planned Maintenance and Condition Based Maintenance help to achieve. It is designed to preserve and restore equipment reliability by replacing worn components before they actually fail. Preventive maintenance activities include partial or complete overhauls at specified periods, oil changes, lubrication, minor adjustments, and so on. In addition, workers can record equipment deterioration so they know to replace or repair worn parts before they cause system failure. The ideal preventive maintenance program would prevent all equipment failure before it occurs.
I have been performing PM on printing presses since 1989. The first press that I preformed PM on was a C700. I was sole electrician in the plant. My call ins went from 3-4 a week to 3-4 a month. This prevented unwanted downtime. Then the company elected to go away from the PM program and the call ins went right back up. I preform hands on PM checking every electrical connection on the entire press. I am surprised at what I find on these PM checks! Once this program is in effect then it would be done on a yearly basic.
