Description
If the percentage of paint left in the can exceeds the TPR by the Job Total Error Tolerance, then this alarm will post. If the paint usage exceeds the TPR by the Job Total Error Tolerance, then also this alarm will post. Most of the time, the can will run out of paint before the paint usage exceeds the TPR by this percentage. This indicates thatthe fluid flow has been restricted or the can has run out of paint.: The paint needs to be calibrated or the adaptive gain for that color valve is too high. The regulator may not be actuating properly from not running a clean out cycle beforethe end of the shift. Often other errorconditions will occur prior to this alarm. Check the alarm log to help detect other symptoms leading to this alarm.
