Maintenance regime is predictive-based
A predictive-based maintenance regime is using consumption thresholds as a criterion for scheduling maintenance.
You selected a predictive-based maintenance regime. The Predictive-based schedule dialog box appears:
Procedure
1. In the Counter field, select the counter that is linked to the asset of the activity definition.
2. In the Consumption threshold field, enter the threshold value at which maintenance activity scheduling must start.
Example:
In Meters , the Planon-estimated consumption for the linked asset is 70 for a period of 365 days.
Let us assume you want to start scheduling maintenance activities for the linked asset at a Consumption threshold of 35.
Planon ProCenter calculates the period (in seconds) needed to reach a consumption of 35. One year = 365 days = 31536000 sec. The following calculation is executed, to establish how many seconds are needed to reach the Consumption threshold of 35:
(31536000 / 70) * 35 = 15768000 sec (this is 182.5 days, which is a half a year)
* 
If there are insufficient readings in Meters to calculate a Planon-estimated consumption, the value specified in the User-estimated consumption field is used in the above calculation.
In the graphical planner, the maintenance activities will recur every 182.5 days.
3. Click OK.
Depending on the entered values, one or more maintenance activities are now scheduled for the selected activity definition.
