Maintenance triggered by operating hours instead of by calendar
The maintenance order is created at 500 operating hours, not on the first Monday of the quarter. We get the counter reading from the controller, from an existing operating-hours counter or, if both are missing, from a brief reading that the shift supervisor logs once a week. Machines in continuous operation therefore get maintenance more often, rarely used ones less often, and both are cheaper than the rigid interval.
Effect Maintenance by load instead of by date
