Interlocks

Note

Please be very careful when touching the interlocks, both hardware and software. A wrong setting of the interlocks might cause the hardware to go in ERROR state and require a Power Cycle causing bigger problems. Be very attentive about the limits and the conditions before activating the interlocks.


AS OF October 2021 ALL SOFTWARE INTERLOCK ARE DISABLED. DO NOT ACTIVATE THEM
IN PARTICULAR VACUUM SOFTWARE INTERLOCK ***MUST*** BE KEPT IN BYPASS BECAUSE THE GAUGE IS NOT PROVIDING RELIABLE READINGS


In the case of a failure of the Cooling system (or vacuum or other hardware failures) interlocks might need to be re-enabled. On the night of 2nd October 2021, we experienced a failure of the SVT Chiller and we had to reset the interlocks. Below there is a screenshot of the Hardware (PLC) and Software interlocks for HPS.
