The following options for setting the Learn cycle to be used are available for selection:
Short

If a Product Registration Photo-eye is fitted, selecting this option means that when a Learn
process is started, the system requests that you pass 8 packs (product samples) through the
detector. The number of packs to be passed is displayed on the screen, reducing as each pack
is passed. Once all 8 packs have been passed the screen closes.
If a Product Registration Photo-eye is NOT fitted, selecting this option means that when a Learn
process is started, the system requests that you pass packs (product samples) through the
detector for a period of 20 seconds. The time remaining to pass packs is displayed on the screen.
Once the time available has reduced to zero the screen closes.

process is started, the system requests that you pass 20 packs (product samples) through the
detector. The number of packs to be passed is displayed on the screen, reducing as each pack

If a Product Registration Photo-eye is NOT fitted, selecting this option means that when a Learn
process is started, the system requests that you pass packs (product samples) through the
detector for a period of 60 seconds. The time remaining to pass packs is displayed on the screen.
Once the time available has reduced to zero the screen closes.
Tolerance
This option is used to add a percentage safety margin to the product signal threshold, captured
and set during the Learn process, to allow for any small variances in product signal values during
normal running conditions.
Tap the arrow to the right of the field to display a drop down list of options for setting the
Tolerance percentage to be used. Options of Min, Low, Med, High and Max are available, with
Med being the default, providing around 15% of tolerance.
IQ Saturation Learn Limit
This option is used to set the maximum saturation signal value to be used during a Full Learn
process. If the signal exceeds this limit then the gain or frequency is automatically reduced.
IQ Saturation Run Limit
This option is used to set the maximum saturation signal value to be used whilst the system is in run
mode. If this value is exceeded a SAT message is displayed.
IQ Limit Min
This option is used to set the lowest value the machine can select for the IQ span during the
Learn process.
IQ Span
Enabling this option displays the I span threshold and Q span threshold options in the Menus >
Learn > Set Up menu. This option requires a Product Registration Photo-eye to be fitted.
