Object Monitoring Template Setup

Object Monitoring and Recording Performance Characteristics

Object monitoring in MAIN-TOOL refers to the monitoring of technical objects with regard to defined performance data for condition-based maintenance. For this purpose, performance characteristics are recorded by posting counter readings, measured values and condition values.

With the interaction of object monitoring functions and performance characteristics, the setup of corresponding activities can be realized, e.g. maintenance intervals can be proposed depending on counter readings. The recording of performance characteristics can also be done by means of a checklist during the execution of maintenance work.

Performance characteristics can be recorded at Component Addresses, Technical Components and Vehicles, but not at Mounting Positions.

Object Monitoring Template Setup

Before performance characteristics can be recorded, the type of performance characteristics must be defined.

Counter Readings examples are:

• A technical component has an operating hours meter.
• A vehicle has a milage indicator.
• A Technical Component has a Switching Counter.

Limit Value-based examples are:

• A technical component has a humidity sensor.
• A vehicle has an oil pressure sensor.
• A component Address has a measuring device for monitoring the room air quality.

Attrition or Consumption-based examples are:

• A technical component has a level indicator.
• A vehicle has a fuel tank.
• At a testbench the attrition of a brake pad is measured.

At the data acquisition based on consumption or wear values, it must be noted that these measured values are understood as absolute values. The current ACTUAL value of the consumption/attrition display is therefore recorded and indicated with a positive sign.

The definition of the performance characteristics type is made by setting up an object monitoring template, as described in the following.

By searching for „Object Monitoring Templates“ the list of same name can be opened:

By clicking on „New” an additional Data Set is created and the card page is opened:

• The code of the Object Monitoring Template is entered in the "Code" field (max. 10 characters). As an example, a counter is to be created, the code could be "Z4711".
• The description of the Object Monitoring Template is entered in the “Description” field (max. 50 characters), e.g. „Counter 4711“.
• In the "Type of Monitoring" field, the type of Performance Characteristics to be used for monitoring is defined. In the example, the "Counter Reading" option is applicable:
  • Counter Reading                e.g. hours of operation counter, Milage, Switching Cycles
  • Threshold/Range               e.g. Temperature range, Condition (0 / 1)
  • Attrition/Consumption     e.g. Oil Consumption

Other optional fields are:

The setup, as shown below, is sufficient and complete for the example:

Note:

• The „Time Schedule No.“ field enables the assignment of a standard time schedule, e.g. reaction to value overrun. For counter readings, the preassignment of a standard time schedule is usually not useful.
• Monitoring cannot be setup via the time schedule but must always take place at the respective technical object.
