Newly replaced PT110 Inficon Gauge BCG450 was found to have one set of faulty contacts. This is preventing the HV power supplies interlock from enabling and turning on the HAM6 HV power supplies. Faulty contacts were bypassed.

Also to note: I enabled and set the pressure/HV interlock CoE parameters for PT170 and PT110 to 1e-5. This had not been done when they were installed. Both are new BCG450 gauges.
