9.29.10 Sean

Mp#5- They had a problem with the cores not working at all.
I went through replacing hoses and checking with the test cylinder and still was not working. Put gages on and had pressure at valve, but not at cylinders.
They would work when i probed valve m,anually.
Then I checked voltages at coils and had none on the set side.
At this point neither core 1 or core 2 were working but I was focusing on #1 for now.
Then I noticed that the output menu 41 slot 6 would energize 2 outputs when trying core 1, but the card was only lighting up the led for pressure and not the set output.
I tried swapping the card and then both sets of cores started working.
I suspected that there was a problem with the output card that I had moved to slot 8 so I left it down until we could find another one.
Ronnie mentioned that they had worked on it today but was not real sure what was done to get it going again.
I would like to know what you found?

Also had the problem with the Chilled water supply being dirty, in which I discovered, after speaking with Ronnie colson, that there is no filtration on the Chilled water system.? I temporarily bypassed the pressure switches on the Thermolators pumping chilled water until the problem is resolved and we have taken the corrective actions.

Call if there are any questions. Enjoy your evening!

Sean.
