Photocell and circuitry which monitors upstream accumulation area or a long conveyor. Toggles the machine to higher speed to clear upstream accumulation, then when the accumulation is reduced and the eye is cleared, speed reduces to normal rate. Benefit: provides for automatic monitoring and clearing of upstream accumulation areas.

AC – standard motor and controller type for most machine models. Benefit: cost effective motion control for moderate speed applications.

Monitors product flow after machine and detects back up on conveyor downstream of the machine, such as from a paused case packer. When the photocell is blocked, the PDC machine is paused. Once the jam is cleared the PDC machine will sound a tone to alert operators and the machine will automatically restart. Benefit: prevents product back ups into the machine; allows the controlled starting and stopping of the line without jamming the machinery, reducing product damage and downtime and increasing productivity.

Numerical dial readouts that note position; used to provide guidance for changeover. Benefit: Reduces Changeover time by indicating positioning of movable assemblies, increasing productivity.
