Green Instec Cold Head Temperature | kpfgreen.currtemp | warmer than | -145 | Celcius | Aux Rack PDU TBC, Aux Rack Network Switch | idea was to choose a value warmer than Chris' potential trial set-points | Thermal control of detector has been lost. | email Chris, Kodi, Steve, Will and Brad |
Green LN2 Dewar Weight | kpflab.greenweight | < | 54 | lbs | in practice should likely be < 52 lbs (the current threshold on the grafana plot). However, setting it higher at 54 allows us to easily test the email alert system as we should get one around 10:45am. | The autofill system has not automatically refilled the dewar holding LN2 used to cool detector. | email Chris, Kodi, Steve, Will and Brad | |

Vacuum Pump Bearing Temperature | kpfvac.pump_temp | > | 55 | C | Vac Cart PDU, Vac Cart Network Switch | gives some margin before the pump's internal alarm at 60 C | Vacuum pump temperature is high. | email Chris, Kodi, Steve, Will and Brad |
Vacuum Pump Frequency | kpfvac.pump_freq | < | 990 | Hz | Vac Cart PDU, Vac Cart Network Switch | nominal value is 1000 Hz. Catches a pump slow-down but gives a 10 Hz buffer for minor fluctuations | The vacuum pump is slowing down, acting erratic, or turning off. Pressure in the main vacuum chamber is not being actively maintained. | email Chris, Kodi, Steve, Will and Brad |
Vacuum Chamber Pressure | kpfvac.vch_hivac | > | 3.00E-05 | Torr | Vac Cart PDU, Vac Cart Network Switch | this is our operational pressure | The main vacuum chamber pressure is rising. | email Chris, Kodi, Steve, Will and Brad |
