What was the problem?
Line 30 sensor was faulting during production.

How did we fixed the issue?
First of all we tryied to reset the line, but it wodidn't wor k, so we called Nova tec Mike. He looked at it and he said that water wengot inside the sensor. He called maintenance to replace the sensor.

How we can prevent this from reoccurring?
Every time when the line is goinges down for cleaning, we need to cover the sensors with a plastic bags, sto it keep the sensors from getting wet.
