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 meet your requirements, please contact your sales partner who will
be able to recommend other suppliers of lighting for the VS 130-2C.
1c
With both arrangements, maintain a clearance between the end of the sensor head and the
code to be read that is suitable for the lens you are using.
Caution:
If you have a large code area and the sensor is inclined at a large angle to the code area and
there is only a short distance between the sensor and code area, this can lead to image
distortion and diminished recognition performance.
2 Install the processing unit so that it is easily accessible for the operator.
Install the external triggering unit, for example a light barrier.

Check the trigger signal. by selecting the "Trg. only" check box in the "Read settings"
group of the "Adjust" task. Check whether VS 130–2 can read the codes with the sensor
head and ring flash in the current position. 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.
Caution: If Exposure is set to Auto V1 or Auto, the code must remain fully in the image for at
least 100 ms.
As soon as after "Recognition" the message "Successfully finished" appears, the code has
been successfully decoded. You will see the result of the read in the "Result" box.
