Photo-Registration
If the system is equipped with a photo eye it can be used to increase the accuracy of the reject device. This is recommended
where discrete packages are inspected. Especially those exceeding 6” in the direction of travel. Photo registered timing can allow
the reject device to accurately reject the product regardless of where the contaminant metal is located within the product.
Options:
Off Photo-registered reject timing is off.
Leading Photo reject timing will register from the leading edge of the product. Recommended for
drop-nose or retracting belt style reject systems.
Length This option of photo reject will register on the leading edge of the product and will
automatically extend the reject duration to compensate for the length of the package. Recommended
when gaps between products cannot be maintained.
Photo Eye Queue Size
The number of products between the photo eye and the reject device at any given time is displayed in this menu and serves as a
check that the photo eye is working properly. As a product passes the photo eye, the queue size increases. When the product
passes the reject device, queue size decreases.
Reject-Special
The following functions are not normally required but are available for special applications:
Time Source
Selects internal clock or external clock source. External clock would be used for variable speed belt applications and requires an
external pulse generator. Contact Goring Kerr for more information
Reject Mode
Normal
Normal is for normal reject applications.
Latching
This can be used to latch the reject relay output, for example with a reject alarm system. The reset will
be done by the alarm reset hard key.
Reverse
This feature is used for applications where it is required to reject products which do not contain
metal. A photo eye is required for this option.
Disable
This inhibits the reject output. WARNING: This will render the detector inoperable.
