Introduction
This menu allows all of the parameters that affect the
operation of the Automatic tracking to be set-up
The automatic tracking feature measures the signals
from packs passing through the detector aperture and
attempts to adjust the phase and sensitivity of the
detector to give the optimum performance for the
current product.
The adjusted values of sensitivity and phase may vary
from the pre-set values due to temperature effects on
the product or due to differences in composition of
successive product batches.
NOTE
When automatic tracking is enabled the current
values for sensitivity and phase (known as the
'tracked values') will be flashed up on to the 'Sens and
Phase' display in the Engineer Mode every few
seconds. The text 'Track...' is also shown on the
display at the same time to indicate that the values
are the 'tracked' values.
In the Running mode the bottom line of the first
display will also flash alternatively between the
'Safeline ltd' and ''Auto. Tracking...' message to
indicate that tracking has been enabled.
Automatic tracking maximum rate
This display is used to set the maximum amount that
the phase is allowed to change between two
succesive pack measurements.
Press the soft key adjacent to Maximum rate to
change the maximum allowable rate of phase change
per pack.
Press the ENTER key when the correct maximum rate
is showing.

Notes for correct operation
The Automatic tracking feature requires that a pack
sensor is fitted and selected in the pack sensor menu.
For correct operation of the Automatic Tracking
feature the 'Sensor Distance' value in the pack sensor
menu must be set as accurately as possible.
Automatic tracking can NOT operate when the 'Speed
range' is set to VARIABLE.
The Product Signal Cancellation feature will be
automatically DISABLED for a product if automatic
tracking is enabled for the same product (and vice
versa)
NOTE
The set-up performed here will apply equally to all
product numbers that are operating in the Automatic
Tracking feature.
NOTE
Remember to record all settings on the Settings
Sheets at the rear of the manual.
