Well I am working on an air cooled mani. It is really slow harvesting. Sometimes it trips the HPC during harvest. I know that there is a 3.5 min limit set by the board, but I have never had one trip the HPC. Is this strictly a harvest issue or is there something lying under the cover? This is a new machine to our company and it was/is in rough shape. We started by cleaning the machine and grid, no good, sometimes it drops others it wont. I have adjusted the bridge sensor to the point that it is making a heavy sheet. The grid is in fine shape, and so are all of the slats. The top of the grid seperates fast. the lower portion of the grid hangs up. Specificly in the lower left corner. Exactly where the hot gas enters the evap during defrost. Not sure what is happening here and thought I would try you guys. Soooo lets here what u think. Is the HPS tripping normal? And I am open to any suggestions.
