| Step | Operation | Description | Controls/Sensors |
|------|-----------|-------------|-----------------|
| 1 | Pallet Placement | Forklift deposits the pallet to be undressed | Photocell B2-BF41620 engaged |
| 2a | Turntable Position - Empty | If turntable is in unload position without pallet, pressing Turntable Rotation button moves it to load position | - Turntable Rotation button<br>- Position sensors |
| 2b | Turntable Position - With Pallet | If turntable has pallet and undressing chain is empty, pressing Turntable Rotation button advances pallet to undressing zone, moving both turntable chain and undressing chain | - Turntable Rotation button<br>- Pallet presence sensors<br>- Chain sensors |
| 2c | Turntable Position - Reset | If turntable is in unload position without pallet, pressing Turntable Rotation button rotates it to load position | - Turntable Rotation button<br>- Position sensors |
| 3 | Pallet Loading | With turntable in load position and empty, pressing Turntable Rotation button moves pallet from loading roller to turntable | - Turntable Rotation button<br>- Loading roller pallet sensor |
| 4 | Pallet Transfer | If turntable has pallet and undressing zone roller is free, pressing Turntable Rotation button stops loading roller and rotates turntable to unload position | - Turntable Rotation button<br>- Pallet presence sensors<br>- Roller status sensors |
| 5 | Pallet Ready | With pallet on undressing chain, pressing Pallet Ready button advances pallet into machine while keeping turntable stationary | - Pallet Ready button<br>- Undressing chain pallet sensor |

**Important Notes:**
- All movement operations must be performed with one of the two buttons pressed
- The first button pressed inhibits movements of the other
- Both buttons are wired to safety inputs

**Special Notes:**
1. Input E7.1 is shown as free in electrical diagram but is actually used in software (Undressing Push-button (X24) - Input Start (Turntable Rotation))
2. R3212 SAFETY is used but the diagram is not updated
3. When adding safety variables, there is a need to update safety-rtg1 DB 1010
