Installation
Step Activity
1b If there is still too much reflection at an angle of 15 °, select an arrangement in which the
sensor head and the ring flash are not concentric.
Note: The mechanism for mounting the ring flash is not supplied with the product.
If the ring flash does not need your requirements, please contact your sales partner who will
be able to recommend other suppliers of lighting for the VS 130.
Ring flash
1c Regardless of the arrangement you select, make sure that you maintain the following
clearances (these clearances depend on the type of sensor head) between the end of the
sensor head and the data matrix code you are reading:
•
6GF2 002 8DA: 110 mm clearance
•
6GF2 002 8EA: 85 mm clearance
Caution:
If the code area is relatively large and the sensor is placed close to the code area at a large
angle, the image may be distorted and thus the clarity will be reduced.
2 Install the processing unit so that it is easily accessible for the operator.
3 Install the external triggering unit, for example a light barrier.
4 Start the setup software on the PG/PC, and switch the processing unit to the Adjust mode.
You then see an image as seen by the sensor head.
•
Check the trigger signal. Activate the "Triggered only" check box in the "Options" group.
Check whether VS 130 can read the codes with the sensor head in its current position
with the ring flash by activating the "Read" check box in the "Options" group (see Manual,
Section A.7). If necessary, correct the trigger point and/or position of the sensor head.
•
Select suitable values for the shutter speed and brightness. The image should not be too
bright.
