Metal Detector Auto-Learn Procedure - Advanced Detection Systems 1200E Series Installation Manual And Owner's Manual

Vegetables, bakery, and pasta produce a smaller signal but are still
considered wet. Dry products, such as paper, plastic, rice, frozen items,
and nuts, produce a small signal or no signal.
Metal detectors are designed to "tune out" or compensate for the signals
created by the product. The following section describes how to set up the
metal detector and compensate for product effect.
METAL DETECTOR AUTO-LEARN PROCEDURE (MENUS 31 THRU 41)
It is a good idea to read the following section "Tips for Successful Auto-
Learn" before beginning the auto-learn process. For the following
procedure, please refer to the menu flow chart.
Navigate to menu 31, select "Learn new product", and press "enter". At
this point you must decide whether your "Product Type" is wet or dry and
if the "Field Strength" should be high or low. An explanation of these
screens is shown earlier in this manual. With pipeline type detectors the
settings should almost always be High and Dry. The display will then
progress to menu 34. Make sure the product pump is stopped and stand away
from the detector while it learns the environment. During this time menu
35 will be shown on the display. After the environment has been learned
the screen will automatically switch to menu 36. Now turn on the product
pump. Press # and again stand clear while the metal detector gets a good
idea of what type of product you will be inspecting. During this time menu
37 will be shown on the display. The detector will automatically progress
through menu 38 and will stop on menu 39. At menu 39 press # and allow
about a second's worth of product to pass through the detector. During
this time menu 40 will be shown on the display. It is very important not
to interfere with the metal detector during this period of time because it
will adversely affect the learn function of the detector. After a second's
worth of product has passed through the detector opening press the # key
again. This completes one "pass" and menu 39 will reappear on the display.
Because of the variety of different products it is not possible to
determine the number of "passes" required for the detector to fully learn
the product. It may require as few as three "passes" or as many as 12.
When the detector has enough passes it will progress to menu 42 and then
to menu 43. At menu 43 select the product number you wish to use for this
product and press enter. This will return you to the "RUN MENU" and the
detector will be ready to inspect the product. If for some reason the
detector was unable to learn the product it will progress to menu 41 and
then back to menu 31. A typical reason for failure would be that the
"Product Type" or "Field Strength" was set incorrectly.
