I mounted the particle counter over the BS chamber attached to the cable tray as seen in Attachment 1. The signal cable runs through an active 30ft cable to the 1x2 rack. the wire is labeled and runs properly through the cable tray. The particle counter is plugged in at the power strip attached near the cable tray. The power cord is also labeled.
I restarted the particle counter service in the c1psl computer in the /etc/systemd/system/ folder using the commands
sudo systemctl restart particleCounter
sudo systemctl status particleCounter
I cannged the usb hub assigned in the service file to ttyUSB0 which is what we saw the computer had named it.
Checking the channels from this elog show the same particle count as when testing with the buttons and checking the screen. It seems that the channels had been down but are now restarted. |
