Forced X1 PT140 Cold Cathode on in Beckhoff
The X1 PT140 Pirani gauge is reading above the software interlock threshold to turn on the Cold Cathode gauge. Per Chandra's request I have bypassed the software interlock by forcing the variables in Beckhoff on h0velx (see attached screenshot).

We may use the intermittent "bad" behavior of the pirani/cable/connection or whatever as an excuse to install the aLIGO wide range gauge sooner rather than later.
