The 12-Inch Cyclotrn PLC-based Macine Safety/Protection System Built by Jimbo.

A Programmable Logic Controller (PLC) based machine-protection system was implemented to allow safe, un-attended operation of the 12-Inch magnet. In the event of high-temperature condition or a coil cooling-water flow loss for more than 10 seconds, the PLC will slowly ramp the magnet down and latch it off, requiring an operator to reset. The PLC safety system became necessary when our 2-D magnet scans took an excess of 24 hours to complete.
