Counter-Based Maintenance 

Purpose

In the case of counter-based maintenance, maintenance activities are performed when the counter of the technical object has reached a particular counter reading, for example, every 100 operating hours. Counter-based maintenance can be employed for technical systems within the process, energy supply, or aviation industries.

Process Flow

The following example describes a process scenario.

You want to check the washers of a pump every time 50,000 liters of water have flowed through it. The pump is represented in the R/3 System as a piece of equipment. The equipment has a counter that measures the volume of water that flows though it. The maintenance of the equipment is based on a performance-based maintenance plan. This maintenance plan is linked to a task list in which all necessary operations for checking the washers are recorded.

In this example, the system creates a maintenance order with the operations from the task list. However, a maintenance notification, service order, or a service notification can also be created.

  1. You create a measuring point for the piece of equipment "Pump". For more information, see Creating Measuring Points and Counters.
  2. You create a measurement document for this measuring point. This document serves as an initial document, meaning that all further counter readings or counter reading differences are calculated on the basis of this measurement document.
  3. The system calculates the planned date by which 50,000 liters must have flowed through the pump. Your technician should check the washers on this planned date.
  4. The system then calculates the call date on which the maintenance order is created. You have defined the call date before the planned date, so that you will have enough time to schedule and dispatch a technician.
  5. You create further measurement documents over the course of time. The volume of water flowing through the pump increases.
  6. Each time you create a new measurement document, the system recalculates the planned date.
  7. The call date is reached when 48,500 liters have flowed through the pump and the system generates a maintenance order with the data from the task list.
  8. Because the system created the maintenance order in good time, your technician can check the pump when the volume has reached 50,000 liters.
