No water in small cup under the slow leak
TCSX is reading HIGH PRESSURE FAULT. See attached picture.
Betsy and I locked and tagged out the CO2X chiller, it will remain off until all needed repairs and safety documents have been completed next week.
At 15:44UTC the chiller tripped off with a HIGH PRESSURE fault, as found by Ibrahim. The CR verbal machine also alerted Ryan with a "low flow" warning.
I went out to the LVEA inspecting the pipes and found that the outgoing CO2X line was disconnected at the quick-connect, image. There was no water on the floor, so the quick-connect did it's job. Maybe this was already loose and we need to add the the pipe inspection FAMIS to inspect these connections, but. there was also lot of work in that area today. I inspected and reconnected the quick-connect, it did not seem damaged.
At out weak point in the chiller lines at the flexible baffle in the pipe bridge, the plastic sheeting that had been attached to catch any spilled water had a small amount of water in it photo, but none leaking out. Expect this water would have been pushed out a small break in the rubber while the chiller was trying to push water around the incomplete lines before the high pressure sensor in the chiller tripped it off. We will inspect and probably repair this part next week. In the meantime with water dripping out of the pipe bridge connection, we are fine to leave the chiller locked out with water in the lines.
TJ, Camilla. Trending the pressure values doesn't tell us much. The chiller appears to go to the high pressure fault and trip off before the pressure channels register a high pressure, see attached. ANALOG1 PSI starts at 65 PSI and ANOLOG2 started at 26 PSI, after the chiller trips off, these increase to 6500 PSI (unphysicial) and 44 PSI. The chiller must have an additional pressure sensor it uses to trip off. Current settings are to trip off at 80 PSI, see FRS 30283.
