EY - New Vacuum Control Sytem Installed WP 5822 
Richard, Patrick, Filiberto

Beckhoff based vacuum control chassis and computer were installed at EY. Sorted out some issues with internal wiring for the 4-20ma inputs (LN2 gauges) inside the beckhoff chassis. Installed shorting plugs for the LN2 control valve watchdog. PT425, PT426, and PT427 guages were connected to the end Y vacuum chassis. We are still trying to sort out some issues with the readback signal for ion pump II411.

I have updated the control room alarm handler. I have also put the CP7 LLCV on PID control. It appears to be recovering well.
