Understanding the Photo-Queue Pack Count

This display function is used only in conveyor applications. The photo-eye queue-pack
function displays the number of packs between the photo-eye and the reject device. This
function is used when your reject device is located a long way downstream of your photo
eye.
This menu is useful because it shows the number of individual units of product between
the photo eye and your reject device. This allows you to verify that the photo eye is
working properly. For example, when product passes the photo eye, the queue-size
increases and, as product passes the reject device, the queue-size decreases.
