Matching Your Photo-Registration Parameters to Your Reject Device
It is important to match your photo-registration parameters to the type of reject device
you are using. Rejects can be triggered in three different ways, as follows.
• By the leading-edge of the product.
• By the middle of the product.
• By the entire length of the product.
Use the following information to select the best photo-registration setting for your
particular application.
Leading-Edge Rejects
This setting is recommended for drop-nose and retracting-belt reject devices.
Middle-of-the-Product Rejects
This setting is recommended for air-pusher and air-jet reject devices.
Entire-Length Rejects
This setting is recommended for applications where the gaps between the units of
product are variable. When gaps vary, the photo eye registers the reject using the
leading edge of the product, but automatically extends the reject duration to
compensate for the length of the product.
