NOTE
The autofocus feature of DS6400 and DX6400 scanners makes Auto
PackTrack Calibration difficult, therefore to assure that the procedure can
correctly calibrate these scanners, it is necessary to set a fixed focus value
which allows the scanner to read all the label positions useful for its
calibration.
2.7.2 Auto PackTrack Parameter Descriptions
The following descriptions refer to the
PackTrack
menu in par. 2.6.3.
Version
: the version of the PCT-8000 being used for calibration. This value can be read from
the barcode labels on the PCT-8000. Each label has the value
vnnn
where
v
is the version
number.
Cal Type
: the XYZ calibration is forced. The coordinates for the three axes are calibrated.
NOTE
For Oscillating Mirror scanner models the scan line must be parallel to the
conveyor direction and only the Y calibration will be performed, (the X and Z
axes will automatically be set to zero).
X Cal
: the Absolute X position is forced. The X coordinate for all scanners is relative to the
precise point (PackTrack Reference Point X, Y, Z = 0).
X Offset
: The X Offset moves the Absolute X coordinate (X, Y, Z= 0) for all the scanners to
the desired point along the X axis which will be measured in step 7 in par. 2.7.3.
Sensor
: calibration will be performed either using the system Presence Sensor and Encoder
(most cases), or the PPA-8000 Photocell Array, for systems where the Presence Sensor or
Encoder are not present (typically Tilt-Tray or Cross-Belt applications).
NOTE
The Auto PackTrack procedure
requires
using the PPA-8000 Photocell
Array for all systems where either the Presence Sensor or the Encoder are
absent (including Continuous Operating Mode and Cargoscan applications).
If using the Presence Sensor and Encoder, the presence sensor must be connected
to the SC6000 PS input and in this menu the parameter is set to
0
. The Encoder Step
parameter must also be set correctly.
If using the PPA-8000 you must set the Photocell distance (
165 mm
). The Photocell
Array must be connected to the SC6000 PS and PSAUX inputs (see the relative
installation manual),
and the Encoder, if present, must be disconnected
.
Z Offset
(if necessary): for packs that are elevated above the conveyor surface (for example
on tilt trays), this parameter sets an offset for the height of a pack so that Z=0 corresponds to
the bottom of the pack.
