Product Signal Cancellation
Phasing out a product effect signal whether
manually or automatically very often does not
eliminate the product signal entirely. The
remaining signal normally means that the
metal detectors sensitivity must be reduced to
eliminate the product signal entirely, and this in
turn leads to reduced performance.
Product Signal Cancellation (PSC or Product
cancellation) aims to eliminate any remaining
product effect signal without the need for
running at reduced sensitivity.
System /Product Requirements
- Fixed speed photogated conveyor
system. The pack sensor must be
mounted before and as close to the head
as possible.
- Minimum belt speed of approximately 10
m/min.
- Maximum pack length 1 m.
- The product effect must be consistent.
- There must be sufficient space between
consecutive packs for the pack sensor to
register them as discrete products.
- Presentation of the product must be
consistent, product guides may be
needed.
- Up to 5 correctly presented products may
be in the aperture at any one time.
If any one of the above requirements are not
met, consult with your supplier.
PSC Limitations
There are certain applications where PSC will
not work:
- loose or variable product
- pipe line systems
- gravity fall systems
- variable speed systems (unless PSC is
setup each time the speed is changed)
PSC Setup
1) Pack sensor calibration
If the reject timer used is a tm2(G), the
following setup is not required.

group.
ii) Select Window Time. When RUN is
displayed, pass the product. After a
Window Time value is displayed, press
Enter.
iii) Reselect the original timer group.
Note - this only needs to be done ONCE.
2) Cancellation Setup
i) Set the following display to YES
(Firmware Version 2.15 or greater).
ii) PSC is available in Prod. No. 1 to 5.
Select the appropriate Prod. No.
iii) Select PHASE and carry out
AUTOMATIC Product adjustment.
iv) At the end of Product adjustment, it
