While Torus was ramping to zero A this morning, the controlled ramp down interlock for LHe Liquid Level for sensor LL8120DP tripped.

The interlock trip level was verified on the PLC to be 65% with a delay time of 1 second.

The archiver shows that LL8120DP dropped below 65% for ~1.4 seconds before returning to ~70%.

Since the liquid level reading is back within limits, the interlock was reset using the EPICS button.
