Changing the Conveyor Rail Width
Sensors and Flags
Mounted on the conveyor are three sensors used to control the
Auto Width Adjust (AWA). These sensors are used to detect the
minimum width, maximum width, and rail alignment. The
sensors are identified as follows:
• Left minimum width (Left Min) sensor
• Right minimum width (Right Min) sensor
• Left maximum width (Left Max) sensor
Each of the three sensors has a corresponding flag mounted on
the moving rail of the conveyor.
The sensors are installed so that each sensor is triggered when
the rails reach a maximum or minimum distance apart (this can
vary between single and dual lane conveyors).
• Minimum width
The default sj5000 minimum rail distance is 50 mm.
However, if a user adjusts the edge clearance, this may vary.
• Maximum width
The maximum width for all conveyors is 510 mm (single
lane). The Left Max is installed so that it triggers when the
rails are 510 mm apart (approximately 2 mm less than the
maximum travel distance).
