I have a CME506RS-1F with "eye issues". Currently the customer is resetting the unit before I get there and they do not know which red light is blinking. I cleaned the eyes and monitored 2 batches. I noticed during harvest that the bin full light flashes only occasionally (if at all) during the ice drop. I am very familiar with this brand of machines and know this is not normal and is responsible for the lock out issues. It seems that the eyes are slow to respond (maybe 2 seconds or more) even when manually blocking the eyes with my hand. The history on this machine is new controller and transformer 12/09 and new eyes 11/09 and 8/09 and 7/09 and 12/08 all per Scotsman tech service. The history goes back even farther than this.
Any constructive ideas? I will monitor this unit again tomorrow to see what is happening.
Thanks in advance for any input.
