Test stand shut down for the weekend

We have a cooling problem with the H2 DTS building. Bubba came back in this evening to take a look at this, in the mean time we have powered down all DTS computers and DC power supplies for the weekend.

After an extensive search for the meaning of the error code displayed on both thermostats indicating a low pressure fault, which in and of itself is odd for both systems to have the exact same fault, I believe I have narrowed the problem down to faulty thermistors. This may have been caused by the recent power outage or may be simply coincidence.

Parts will need to be ordered next week.

I will follow up with a FRS.
