Path: Administration > Planning > Planned Shutdowns
Overview
Planned shutdowns are the periods during which a piece of equipment is deliberately stopped — for preventive maintenance, a plant closure, breaks or scheduled non-production periods, for instance. In PerfTrak, these stoppages belong to the Loading category of the loss tree.
The "Loading" category in the loss tree
The PerfTrak loss tree follows the main principles of the AFNOR standard to categorise loss types. The Loading category is specifically dedicated to planned shutdowns. It is one of the non-editable categories in the left-hand column of the loss tree — together with Availability, Performance, Quality and Custom — which serve as the reference for calculating the indicators.
The level 1 and level 2 stoppage causes you create in your loss tree under the "Loading" category correspond to the different types of planned shutdown specific to your organisation.
Automated plant shutdown
PerfTrak has an automated plant shutdown mechanism, identified by the PS dot in the loss tree. This plant shutdown typically corresponds to a factory closure and is an automated cause that does not have to be informed by the operator.
To configure it:
- First create the corresponding cause in your loss tree — for example "Plant closure" or "Plant shutdown".
- Then go to the Configuration sub-tab of the loss tree.
- Assign that cause to Plant Shutdown (PS).
Once configured, the PS dot appears to the right of the selected level 2 loss.
Manual stoppage from the tablet
The operator can also trigger a production stoppage manually from the tablet — during the weekend, for instance. To do so:
- The operator clicks Sign out in the tablet menu.
- They press the Stop Production button — this option must have been enabled beforehand in the tablet Settings.
- The loss is automatically informed as a plant shutdown.
The system restarts automatically as soon as a signal from the module indicates that the machine is running again, which avoids any loss of information.
