The air-bake oven in the LSB optics lab has had a new controller installed. The controller is capable of handling ramp and soak functions. Large changes to the oven (opening or closing the flue, etc.) will now need the autotune process after the change has been made if an accurate temperature ramping is desired. More info can be found here: Omega Manual. The controller can run a program with 30 setpoints to ramp and soak at different rates and hold times.

Attached is a graph of a ramp up from 40 to 70 degrees in 30 minutes that was run as a test. I will attach a more detailed report to this when it is finished, but if anyone would like to use that oven I will be more than happy to give a run down on how to set it up. This controller really suffers from a Blinking 12 problem.

Also attached is the modified wiring schematic that represents what is now in use for the oven. As you can see the controller will stay on even with the power switch off. This is how I intended it to be, the fan and heater will be de-energized by the switch still.
