Shutdown dust monitor #2 at End-Y. This dust monitor is used to monitor the BSC10 cleanroom during chamber opening. As the chamber is currently closed this monitor is not needed. Dust monitor #1 is running monitoring the general room air of the VEA. Alarms on this monitor should be investigated as per normal procedures. With DM #2 powered down, the network connection with DM #1 would drop. DM #1 would continually flip between "Sampling" and "Count Interrupted". After swapping cables and recycling the comptroller, the dust monitor, weather station, and restarting the various bits of software, still had no communications with DM #1. Patrick pointed out there is pin swap between the comptroller and the dust monitor. After installing the correct cable, the monitor is up and running correctly. I will adjust the alarm levels to reflect general monitoring levels.
