[Dsg-rich] moisture transducer wiring in RICH cRIO chassis and LabVIEW changes

[Valery Kubarovsky]

Hi Tyler, 
You can turn OFF HV and LV using slow control GUI just in case.

>> Hello Valery and Marco Contalbrigo,

>> This afternoon, we are planning to install the moisture transducer on the RICH
>> N2 exhaust. N2 Flow to RICH will not be interrupted.

>> To read the transducer on the cRIO, we may need to power the cRIO chassis down
>> to wire the sensor to the 24 V supply.

>> We will also need to modify the hardware interlock LabVIEW program on the cRIO
>> to read out the sensor.

>> Are there any presently ongoing RICH tests? We would like to make the necessary
>> software and wiring changes tomorrow.

>> Best regards,
>> Tyler
