With the CDS and Beckhoff work yesterday some large numbers got into the CHILLER_SET_POINT filters which requested a low setpoint for CO2X, the laser faulted and turned of when it got to 15degC at 22:06UTC yesterday. This morning I turned it back on and set H1:TCS-ITMY_CO2_CHILLER_SERVO_GAIN_GAIN from 1 to 0 (as in alog 75715) to stop any feedback form the laser being off gong to the chiller).
TJ and I plan to make sure the H1:TCS-ITMX_CO2_PZT_SERVO_GAIN_SW2R is correctly turned on and off in the Guardian code when the CO2 lasers are taken DOWN to avoid this in future.
This is correctly turned off in DOWN but the Beckhoff work on this day changed the settings (plot) and we did not rerun the DOWN state. TJ has added a detector to TCS_ITM{X,Y}_CO2 guardians to rerun DOWN state if H1:TCS-ITMX_CO2_PZT_SERVO_GAIN_OUTPUT goes >1000. Usually below 100 but has an intergrator that can act strangely on Beckhoff channel changes. Tested and loaded in both X and Y.
