Hello, 

Today, we connected five humidity and temperature sensors in the RICH nitrogen body for use during the nitrogen tests. 

The keyed override switch was also installed so the cRIO can be restarted without disabling HV or LV. The position of the key is set to " override off ". Restarting the cRIO will result in HV/LV being disabled. 

The cRIO is now running the latest interlock program and can be used during any tests over the weekend. The enable/disable status for sensors and the limits will need to be verified before starting cosmic runs. 

Best regards, 
Tyler
