Reason Trees are used to select the available downtime reasons for each piece of equipment. When an operator records downtime in Data Collect they must select one of the pre specified reasons.
Downtime reasons are placed under two levels of categorisation. For example:
| Top Level | 2nd Level | Downtime Reason |
|
Electrical |
Power supply |
Power outage |
|
Spike |
||
|
Mechanical |
Motor |
Split bearings |
|
Overheating |
||
|
Rollers |
Broken |
|
|
Sticking |
||
|
Misaligned |
1. Select the Equipment & Downtime tab.
2. Click Reason Tree.
A list of the existing Reason Trees is displayed.
3. Click the add icon (
) below the left Reason Trees panel.
4. Enter a name for the Reason Tree.
5. Click OK.
The new reason tree is added.
6. Drag and drop a Top Level Category from the Add Items panel on the right into the middle panel.
The following screen is shown:
7. Enter a name and description for the category.
8. Select a Time Category (the list is taken from the Time Model).
9. If required, you can enable automated data collection. This is the described in another section (see here).
10. Click OK.
The item is added to the Reason Tree.
11. You can now build the rest of the Reason Tree by dragging items from the right panel into the center panel, remembering that 2nd Level Categories must be added to Top Level Categories whereas Downtime Reasons must be added to 2nd Level Categories.
When you add a 2nd Level Category or Downtime Reason it will automatically be assigned the time category of the level above, unless it is modified.
It is also possible to use the add icon () below the right Reason Trees panel to add items.
12. Assign the reason tree to equipment in the Downtime tab for that equipment in the equipment hierarchy. For information on how to do this see here.
