Mounting the Read Head
Mount the PGV... read head on the automated guided vehicle using the four screws on the
mounting adapter on the read head. Mount the read head in such a way that the lens with the
ring light and camera module are directed toward the colored tape.
The mounting must be stable enough so that the read head does not leave its depth of focus
range during operation.
The distance between the read head and the floor should be the same as the read distance of
the read head.
Optimum Read Distance
Hysteresis
If the read head has detected a colored tape, this colored tape can move in the Y direction from
the zero point within the viewing window. The maximum Y value at which the read head can still
capture this distance is designated as
Y Value Out
in the following table.
If the read head swivels onto a colored tape, the read head can capture the distance of the
colored tape from the zero point only if the tape is less than a certain distance away from the
zero point. This distance is designated as
Y value In
in the following table. The difference
between Y Value Out and Y Value In is the hysteresis. See "Distance Output" on page 19.
