Adjusting the camera shutter time and camera gain
Select the
Configuration > Configure OIT system
menu item from the main bar
and open the tab
Image/Testing
.
1. Set the camera shutter time to 2000 and the camera gain to 1.
2. Pass the code carrier in front of the OIT system. The speed should be the
same as it will be in normal operation.
3. Now check the captured image. The holes in the code sheet should appear
sharp. If the holes are not precisely round, reduce the camera shutter time
and repeat the procedure.
If the holes in the code sheet appear sharp, then changes to the camera
shutter time are complete.
4. Check the illumination of the code carrier. If the camera image is too dark,
increase the camera gain.
Also check the LED display on the illumination unit (Stability) or the LED
indicator in the OITControl software (OIT warnings) (both have the same
functions). If the LED lights up, then the gain is set too high.
The settings made can be applied to all other OIT systems in the same
environment. The OIT system uses infrared illumination and is therefore not
susceptible to interference from other types of illumination. Direct sunlight or very
high temperatures (> 800
°
C) only can cause disturbances to the code sheet. The
settings can be used when there are slight deviations from the preset distance (
±
50 mm).
