Add Additional Meter to Service Revision

Use this document to add different types of additional meters to a service revision.

These are the available types of meters:

  • Competing meters
  • Time-phased meters
  • Fixed date meters
  • Absolute meters

Outcome

Different types of meters are connected to the service revision and you have defined how the service is scheduled. See the descriptions under each heading in the Step Action list for further information.

Together with operation plans and calendar time, the defined settings are used to calculate when different services are performed.

Information about the additional meters is stored in the AOMPGL table for maintenance limits.

Information about service dates is stored in the MOSEDT table.

Before you start

  • Define a service revision in 'Service Revision. Open' (ECS300).
  • Define the meter in 'Meter. Open' (MMS051).
  • Linked the meters to be used against the service to the product or equipment on 'Item. Open' (MMS001/J) and 'Item. Connect Meter' (MMS004).
  • If an absolute meter is to be connected to a service revision, define this meter as an absolute meter in 'Meter. Open' (MMS051).
  • If an absolute meter is to be connected to a service revision, define the revision as an unscheduled service.

Follow these steps

Add or maintain a maintenance limit

  1. Start 'Service Revision. Open' (ECS300/B).
  2. Highlight the service revision to add or maintain, and select option 18='Maintenance Limits' to show 'Service Revision. Connect Maint Limits' (ECS311/B).
  3. Set panel sequence E and sorting order 1.

  4. Select a meter to link to the service revision and a threshold (optional). Select New or Change to show the E panel.

    The threshold value indicates the first occurrence of the service. The interval is different once the threshold is reached.

  5. Specify whether inventory time affects the limits, and whether the threshold value represents the lifetime limit for the maintenance object.

    Set inventory maintenance to 2 to ensure correct calculation of maintenance intervals at all times.

  6. Specify a repeat interval to indicate the frequency of the service.

  7. Specify operational and economical tolerances. These fields are optional.

    The operational tolerance indicates how much the service is exceeded.

    Economical tolerance 2 indicates how much earlier the service is performed before it becomes uneconomical.

    In combination with the field 'Reset next due date', the economical tolerance 2 is also used to control how early a service is performed without resetting the next due calculation.

  8. Select the 'Reset next due date' check box to reset the start date for the next due calculation when the service is performed earlier than the economical tolerance date. The field is used only if Adjust code=0 on the service header and service history is approved.
  9. Specify a sampling percentage and whether simulation is performed. This information is optional and normally not used.
  10. Press Enter to save.

Add Competing Meter to Service Revision

Add competing meters to trigger the service when either the first or the second meter reaches the limit. For example, a regular car service is performed at 15,000 kilometers or every 12 months, whichever comes first.

  1. Start (ECS300/B).

  2. Highlight the service revision to add meters, and select option 18='Maintenance Limits' to show (ECS311/B).

  3. Set panel sequence E and sorting order 1.

  4. Select a meter to link to the service revision and a threshold (optional). Select New to show the E panel.

    The threshold value indicates the first occurrence of the service. The interval is different once the threshold is reached.

  5. Specify whether inventory time affects the limits, and whether the threshold value represents the lifetime limit for the maintenance object.

    Set inventory maintenance to 2 to ensure correct calculation of maintenance intervals at all times.

  6. Specify a repeat interval to indicate the frequency of the service.

  7. Specify operational and economical tolerances. These fields are optional.

    The operational tolerance indicates how much the service is exceeded.

    Economical tolerance 2 indicates how much earlier the service is performed before it becomes uneconomical.

  8. Specify a sampling percentage and whether simulation is performed. This information is optional and normally not used.

  9. Press Enter to save.

Add Time-Phased Meter

Use a time-phased meter when the frequency of a service changes over time. For example, a service has a frequency of 50,000 kilometers for the first 200,000 kilometers, and a frequency of 25,000 kilometers thereafter.

  1. Start (ECS300/B).

  2. Highlight the service revision to add meters, and select option 18='Maintenance Limits' to show (ECS311/B).

  3. Set panel sequence E and sorting order 1.

  4. Select a meter to define the time-phased interval and a threshold. Select New to show the E panel.

    One limit must already exist for this meter.

    The threshold equals the meter value at which the interval should change.

  5. Specify whether inventory time affects the limits.

    Set inventory time to 2 to ensure correct calculation of maintenance intervals at all times.

  6. Specify the new interval.

  7. Specify operational and economical tolerances. These fields are optional.

    The operational tolerance indicates how much the service is exceeded.

    Economical tolerance 2 indicates how much earlier the service is performed before it becomes uneconomical.

  8. Specify a sampling percentage and whether simulation is performed. This information is optional and normally not used.

  9. Press Enter to save.

Add Fixed Date Meter

Use a fixed date meter to schedule the service for particular dates or days of the week. If you define a fixed date meter, this overrides all other meter options.

Service dates are defined manually or through automatic entry. Manual entry is described in steps 2 to 4. Automatic entry is described in steps 6 to 12.

  1. Start (ECS300/B).

  2. Highlight the service revision to add meters, and select option 29='Service Dates' to show (ECS311/B).

  3. Select panel sequence E and sorting order 1.

  4. Specify the start date and select New to show the E panel.

  5. Press Enter to add the service date and save.

  6. Press F13 to show the P panel.

  7. For weekly services, select the days that the service is allowed to be scheduled on. Select 1 in 'Day type' field.

  8. For monthly services, select 1 in 'Day type' field and specify a value in 'On day' field to define the day of the month on which the service is scheduled.

  9. For daily services, select 2 in 'Day type' field if only working days are considered. A working day is a day in the 'System Calendar. Open' (CRS900), with general capacity. If day type is 2, the fixed service days are not considered.

  10. Press Enter to return to the B panel.
  11. Specify a start date for the meter generation and select F14='Create calendar'.
  12. Specify the date to which the service dates continue.
  13. Press Enter to save.

    The system calculates all service dates until the end date. The repeat interval is taken into account so that, for example, a service with an interval of four weeks receives service dates every four weeks on the selected day.

    For daily services with day type 1, only days marked as fixed service days are considered if the maintenance limit is matched. Otherwise, the service is created on the next fixed day selected. For daily services with day type 2, only working days are considered. This avoids service dates on weekends and public holidays, and the maintenance limit does not count non‑working days. For example, a service with a two days limit and day type 2 is scheduled on Monday, Wednesday, and Friday one week, and Tuesday and Thursday the next week.

Add Absolute Meter

Use an absolute meter to trigger a service based on the condition of the equipment or product rather than on time. A service with an absolute meter is triggered when reported values are outside specified limits. For example, a service for checking the tires on a bus with a meter that is defined as a thickness meter linked to the service.

When a meter value outside the limits is reported, the service is triggered. In this example, the service includes an operation for changing the tires.

  1. Start (ECS300/B).

  2. Highlight the service revision to add meters, and select option 18='Maintenance Limits' to show (ECS311/B).

    Note: This service revision is not scheduled. Rather, this service revision describes the action performed when inspection results are outside the limits. In this example, the service includes an operation for changing the worn tires.

  3. Select an absolute meter that is connected to the equipment or product. Specify a minimum meter value in the 'Threshold' field. Select New to show the E panel.

    The 'Threshold'd field acts as the minimum value field for absolute meters. The field heading changes to 'Min value' on the E panel.

  4. Specify the maximum value that is permitted. Specify a trend value, if applicable. Press Enter to save.

    If a trend value is specified, the service is triggered if the reported value in (MOS160) is greater than this value.
