Note: the procedure varies slightly between the PSC1 and PSC2 interlock boards. Rather than make two procedures that are 95% the same, this procedure covers both boards; When we come to a choice, we give a little 2-line table with the PSC1 instruction on line 1, and the PSC2 instruction on line 2. The main source of difference is that PSC1 has a single CPLD; PSC2 has 2 CPLDs.

Requirements:

Initial state: all PDS front panel switches off, PCON computer off.
