BSC8 PT-180 Gauge Removed and Replaced
(Travis, Gerardo)
We removed the old gauge a BCG-450 and installed a new one a BPG-552. Since the gauge at this location does not play role with relays and such, the old pigtail did just fine, provided the power to the new gauge. The new gauge is powered on and connected to the same EtherCAT cable as the one that that we removed. Dead volume of this assembly is getting pumped down with a small can turbo pump and an aux-cart, and a very long flex hose, and probably will continue to pump over the weekend.
No issues were encountered while replacing the gauge.

Aux-cart and all other accessories have been removed from this gauge.
We need to leak check the conflat on this new gauge.
