Hi Marc,


I will fill the detectors Tuesday afternoon when it gets warmer.  We can test the H2O sensor then if you like.


Regards,

Bob

Hi Bob,

I have connected the H2O sensor to the Gas Controls, the initial readback value was ~2000 ppm and steadily dropping. In less than 20 minutes it has decreased to around 1100 ppm, and was still dropping.

If possible it would be helpful if we could run some gas from the supply tank directly through the transducer so we could have a baseline for reference. We also need to establish the return H2O set point, which will close the hall supply solenoid. Currently, the solenoid is unplugged from the AC relay.

This will be ready for use as soon as I can do some testing and update the FC cRIO software. I'll coordinate that with you and the RC.

Hi Marc and Brian,

The H2O sensor is installed and cabled.

The system is working fine now.  I will have to wait for warmer weather
tomorrow to fill up sector 3.

Thanks,
Bob
