Operating conditions:
The Tracking limits menu is only available if Tracker has been set to ON in the User
options menu. For this option to be available, a photo-eye must be fitted for product
registration purposes.
Tracking is product relative, i.e. the function can be turned on or off for each of the 100
product memories each memory can contain unique settings.
Tracker initialisation will occur whenever:
The detector is powered on:
The running product is changed.
The Tracking limits parameters are changed.
Upon completion of the product calibration routine the derived working threshold will be
used unless the product signal initiates a change.
The following table describes the Tracking menu:

Configuration and Set up Information
Advice
Can be set on a per product basis.
Commences at the calibrated working
threshold.
The value cannot be set less than the
calibrated working threshold but may be
increased up to the value of the Max limit.
Commences at twice
working threshold. The value cannot be
set less than the calibrated working
threshold but may be increased up to the
value of your choice. However it is
strongly advised to set this value to just
greater than the typical amount by which
the product signal is expected to change.
All signals that exceed this value will be
rejected.
Once the highest tracking limit value has
been entered the value can be locked to
prevent a change should a re-calibration
occur.
The factor range is 0 - 9 where 9 is the
largest. The default value is 1.
The rolling pack number included within
the tracker calculations. The range is 1 -
100 where 100 is the finest control. The
default value is 10.
