Overhead Electrical Services
The Electrical Services Box may be mounted overhead instead of at the front of the conveyor as is
standard.
Product Guides
Product guides are useful for centring products
through the detector aperture and controlling
product presentation to prevent skewing.
Three types are available. One type is situated
at the infeed to the conveyor only, the second is
fitted through the search head, and the third is
fitted along the full length of the conveyor. The
guides can easily be adjusted to suit the width of
a specific product.
Product Registration Photo-eye
Conveyors that are supplied with a pusher reject are fitted with a product registration photo-eye which
allows the system to count the total number of packs that have been presented for inspection. It also
provides the system with a timing reference for activating reject devices and works in conjunction with
other optionally fitted photo-eyes to confirm that good packs have been passed and bad packs
rejected..
As standard, the photo-eye is mounted on the side of the conveyor. It is used to register the position
of the products on the conveyor. As an option, the photo-eye may be mounted directly above the belt.
This is particularly suitable for the registration of products that have very little depth.
PVS Indicator Lamp
Illuminates when a pre-programmed Performance Validation System test is required. The normal
colour is blue but it can be white if the system uses two search heads.
Reject Actuation Confirmation
Stops the conveyor when a contaminated product is detected and the reject solenoid fails to trigger.
Reject Confirmation with Photo-eye
A photo-eye is fitted across the entrance to the reject collection device to confirm that a pack has
been rejected.
Lockable Reject Bin and Status Monitor
The reject bin door is locked and unlocked through the user interface rather than with a standard key.
Permission to open and lock the door is provided in the software to users with a Level 2 Supervisor
access account. The status of the door lock is monitored by the software.
Pack Check Photo-eye
A photo-eye fitted onto the outfeed section of the conveyor after the reject mechanism works in
conjunction with the Product Registration photo-eye to confirm that a good pack exits the system but
a bad pack does not.
