Process quality
The process quality indicates the quality of the light level currently being received. The
MLG-2 analyzes the light level received when the light path is unblocked and compares
this to the values after the last teach-in process.
If the received values are getting worse, the process quality drops.
Possible causes of a drop in process quality include:
•
Contamination or fogging of the front screen of the sender and/or receiver
•
Misalignment
•
Continuous partial blocking of a light beam or several light beams
