Settings for performance based maintenance plan

Question

Hi experts,
Incase of hour or Km dependent performance base plan, how we can fix the reading (In hours or Km) limit or period of order generation? what is the impact of annual estimate? Please give me an example with all readings.
Regards,

Answer 1

When you create a plan with a counter (Associate a measurement point of counter type to the same), then you would be able to specify at what intervals (Counter readings for this measurement point), the call object associated to the Maintenance plan should be generated.
The actual call date for this maintenance plan however depends on the "Annual estimate " for the measurement point counter and also the actual counter readings captured for the measurement point
For ex: Annual estimate maintained for the Point : 12,000 Miles .Maintenance for this equipment should be triggered for every 1000 Miles (This should be the counter interval maintained for the Maintenance plan). Based on the above the maintenance plan would generated a call every one month (Annual estimate / period).As an example,  when this Maintenance plan is scheduled for 1 yr, then 12 maintenance calls will be generated one each for every month. The actual and scheduled dates for the call depends on the various other scheduling parameters maintained for the Plan.
Its critical for any counter based maintenance plan that the counter reading is Captured , Through measurement documents regularly, EVEN IF THERE IS NO CHANGE TO THE COUNTER READING, Otherwise, the system generates call objects (for example, maintenance orders) based on the estimated annual performance entered for the counter, even though the counter reading has not in reality been reached.
for ex: owing to a vehicle breakdown/ repair if the vehicle has been in repair shop for a month,To avoid a maintenance order being created before it is needed, you maintain the new total counter reading in the system regularly over the period of the month. You then reschedule the maintenance plan using IP30, and the call date is recalculated based on the updated counter reading. In this case, the call date would be later.
