Detection of Contamination of Press Belt Main Motor

This reduces the man hours required for periodic belt aging and contamination checks. Issues caused by belt breaks that suddenly occur between periodic checks can be prevented. Press belts are consumable parts, and need to be periodically checked and replaced before breaking. Periodic maintenance is carried out, but this requires man hours and there can be issues such as breaking or slipping between maintenance periods. It is possible to perform maintenance on an as-needed basis rather than a regular basis.
