I turned the HWS chassis back on and the SLEDs power came back up. 1.8 for IX and 0.4 for IY we could think about replacing them but at these power levels before the vent we still had clear data.

To get the code to start taking data I had to press the output button the the HWS camera power supply (under optical table), this probably hadn't been reset since the April power outage.

Then followed TCS wiki  to initialize cameras, set frequency to 1Hz each and restart code (old references).
