The first few weeks of SAD-24, they need to be on for the warm up of the HMS dipole magnet in a controlled manner.</div>

After the HMS dipole has stabilized then the PLCS could be brought down, one at a time. The patch should be installed into one plc, off line, tested and verified before the other PLC is patched.</div>

It is not just having the magnets turned off that matters, as the PLCs also control Hall C cryogenics and spectrometer rotation.<br>
