When the “PLEASE WAIT” screen goes off, place the product on the conveyor belt and allow it to pass through
the detector aperture. If the product has enough signal, the “PLEASE WAIT” screen will appear again. When
the detector has enough samples, the “LEARN SUCCESSFUL” screen will appear. The detector will usually
require 2-3 passes of the product. Some products with large signals may require more passes. Some products
have almost no signal and it is more difficult for the detector to “learn”. If, when passing the product through
the detector, the “PLEASE WAIT” screen does NOT appear, then allow the learn timer to reach zero. The
detector will then resort to default settings for the best sensitivity.
If, during the learn process, the detector head was bumped or someone’s watch, ring, or hands get too close to
the detector opening, then press the “ABORT LEARN” button to discontinue the learn session and begin again.
LEARN MARGIN:
There is an additional button on the learn screen named “LEARN MARGIN”. This
has to do with the consistency of the product. When the detector learns the product signal it sets the detect point
at some level above the product signal. When metal comes through the detector it makes a large enough signal
to go above the detect point and the detector “sees” metal. If the product is very consistent, the learn margin
can be set close to the product signal. If the product is not consistent at all, the learn margin must be set farther
from the product signal to allow for varying product signals. The learn margin is variable from 1-250. The
default margin is set at the factory to 25. This will handle most products and would not normally need to be
changed. If, after successfully learning a product, the detector occasionally triggers on good product, it may be
necessary to increase the margin. A setting of 1 setting is very “tight” and a setting of 100 is very “loose”. In
general, if the setting is too “tight” it will result in false triggers, and if the setting is too “loose”, it will result in
reduced sensitivity.
AUTOMATIC FEED LEARN/RELEARN:
After selecting “HAND FEED” the following screen
will appear:
When the “Keep Running Product” screen appears, be sure the conveyor belt is running and allow product to
pass through the detector aperture. When the detector has enough samples, the “LEARN SUCCESSFUL”
screen will appear.
If, during the learn process, someone’s watch, ring, or hands get too close to the detector opening, then press the
“ABORT LEARN” button to discontinue the learn session and begin again.
