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 - 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 - Pallet presence sensors - 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 - 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 - 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 - Pallet presence sensors - 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 - 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:

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