Leaving the Main Course
In case a vehicle has to leave the main course, the ancillary track has to start as shown
in Figure 3. In addition to the main course, only one ancillary track may be within the
view of the camera. It is therefore essential to locate the branch-offs on the right and
left side with an offset at places where two courses cross.
The instruction to leave the main course in order to get to one of the ancillary tracks
can be given either by the track selection input serial or by using the CAN bus.
This instruction is to be set just before the branch-off gets in sight - and to be reset just
after the branch-off has disappeared from sight.

Additional Commissioning Steps
Use the built-in parameter menu for setting the parameters (refer to chapter 4 on page
19). Offset and deviation of the analog output voltage are adjustable in steps of 20 mV
using the menu
(O)utput-Input Settings
. For the exact setting, it is necessary
to check the output voltage with a voltameter.
Place the camera at the final installation height above a section of the guidance line
with bad quality and set straight forward travel.
-
Enter the reading height and track width in millimeters in the menu Image Set-
tings. In case the camera G 73841ZB is used, the calibration factor is already fac-
tory-set. For other cameras, it is necessary to re-determine the calibration factor
within the submenu
Adjust width of track
(refer to Figure 11 on page 25).
-
Also select the track structure in this menu: black on white or white on black.
-
If different sets of parameters are to be used, those sets have to be entered here
or in the corresponding SDOs of the CANopen® protocol. For each set of param-
eters different inputs are possible when using the following variables:
Branch 1
“Sight window“ of
the sensor
Feed in
Branch 2
