Enter Maintenance Plan
Explanation
This activity is used to create a maintenance plan for valid
combinations of serial parts and maintenance groups of a maintenance
program. The maintenance plan indicates, using operation intervals and calendar
intervals, when the equipment is due for maintenance.
Based on the maintenance plan and the operational frequency, a due
calculation that generates maintenance actions for the event plan is executed
each night. For every maintenance code in the plan, an appropriate calculation
rule is indicated. Normally, one of the maintenance codes will have the Overhaul
calculation rule. If the maintenance plan does not entirely consist of recurring
maintenance codes, one of the maintenance codes with the calculation rule
Overhaul must Cycle the maintenance program for the due calculation to work
correctly. To perform a Cycle means that all values after overhaul will be
reset to zero. If this is disregarded, the due calculation for maintenance
intervals will not work correctly. You cannot delete a maintenance code if it is connected to maintenance actions for
the serial objects. For more
information about the rules when registering maintenance plans, follow this
link: Interval Based Maintenance Program.
Prerequisites
- A maintenance program to create a maintenance plan
for must exist.
- Serial parts must be defined for the maintenance
program.
- Maintenance groups must be defined for the
maintenance program.
- Maintenance codes (valid to enter for a serial part,
a maintenance group and a maintenance program on a maintenance plan) must be defined as basic data in
the Maintenance Program Basic
Data/Maint Code tab.
System Effects
A maintenance plan is defined for a given maintenance
program, serial part and maintenance group. A task calculation for serials
connected to the maintenance program with the defined maintenance plan can be
executed from the
Serial Maintenance window. It will be possible to
enter the start value information in the
Component Life/Interval Maint
tab.
The maintenance codes entered in the
maintenance plan are automatically created as
valid maintenance codes for all revisions of the serial part and can be
connected to instructions. For more information, follow this link:

Procedure
Select from the following options to create a maintenance plan for a
maintenance program:
Option 01:
- Open the
Maintenance Plan window and query (F3) for the
necessary maintenance program, part revision and maintenance group for which
you want to create a maintenance plan.
- To create an interval for a primary releasing operational parameter for
the maintenance plan, create a new record (F5) in the upper table of the
Intervals tab.
- Enter the preferred maintenance code for the maintenance plan in the
Maint Code field. Use the List of Values to select a value.
- Enter the preferred maintenance interval for the maintenance plan in the
Maint Interval field.
- Select the Recurring Calculation check box if the maintenance
code is to be calculated at recurring intervals. Specify the Recurring
Interval and/or the Recurring Cal. Interval. Note that the
Recurring Cal. Unit is required when a recurring calendar interval is
specified.
- Select the Use Tolerance check box if tolerances are to be used
for the given maintenance code. Specify the Lower Tolerance and the
Upper Tolerance limits. If necessary, select the Adjust Above +
Tolerance check box as well.
- To enable adjustment of calendar based intervals, select the Cal. Int. - Adjust if done Early
check box and the Cal.
Int. - Adjust if done Late check box.
- When the Cal. Int. - Adjust if done
Early check box is selected, the next due date will always follow the due date of the
previous execution whenever the maintenance has been performed too early.
- When the Cal. Int. - Adjust if done Late check box is selected, the
next due date will always follow the due date of the previous execution
whenever the maintenance has been performed too late.
- Note that the settings for Cal. Int.
- Adjust if done Early and Cal. Int. - Adjust if done Late does
not have any effect if the Based on Performed Date has been specified.
- In the Days Forewarning field, specify the number of dates before
the maintenance code's due date that the maintenance action is to become
available for planning.
- In the Duration Workshop field, specify the number of days the
equipment is expected to be in the workshop.
- In the Duration Unit field, specify the unit of
measurement for the duration in the workshop.
- In the Calculation Rule field, specify the calculation rule for
the given maintenance code. The calculation rule Inspection is
selected by default.
- In the Cycle field, indicate whether the execution of maintenance
actions for the maintenance code will trigger a zero setting of accumulators
in the operational record. Note: For parts that are not overhauled
the value must always be No Cycle.
- In the Task Remark field, enter any additional
information on the interval maintenance. Entering a value in this field is
optional. Double-clicking on the field will open
a text editor where you can enter text in a more convenient fashion. When a task is created for the
interval maintenance, this information will be transferred to the Task Remark
field of the corresponding task record on the maintenance order.
- Save the record (F12).
- To create an interval for a secondary releasing operational parameter
for the maintenance plan, create a new record (F5) in the lower table of the
Intervals tab.
- In the Operational Parameter field, enter the secondary releasing
operational parameter. Use the List of Values to select a valid value.
- In the Maint Interval field, enter the required maintenance
interval.
- Save the record (F12).
Option 02:
- Open the
Define Maintenance Program window and query (F3)
for the necessary maintenance program.
- Right-click and click Maintenance Plan. The
Maintenance Plan window is opened with all serial parts and maintenance groups
that are connected to the maintenance program and for which you want to
create maintenance plans.
- To create an interval for a primary and/or secondary releasing
operational parameter for the maintenance plan, continue with steps 2 - 18
detailed in Option 01.
Option 03:
- Open the
Define Maintenance Program
window and query (F3)
for the necessary maintenance program.
- Click the
Maintenance Groups tab.
- Select the row containing the part number you want, right-click and then
click Maintenance Plan. The
Maintenance Plan window is
opened with the serial part, maintenance group and maintenance program for
which you want to create a maintenance plan.
- To create an interval for a primary and/or secondary releasing
operational parameter for the maintenance plan, continue with steps 2 - 18
detailed in Option 01.
