The program in the Octagon controller stopped running. The software controller was trying to correct the output current, but the Octagon was not responding to the commands. In the attached picture we can see the output current drifting upwards as the software is trying to set the current lower and lower. Resetting the controller will zero stuff and change the state of a switch or two. The only controlled way to reload the program, that I could think of, is to dump the magnet and cycle power on the Dynapower when the current is 0 amps. Howard hit the emergency stop button on the front of the power supply and cycled power after he came back from lunch.
