I had left the CTB heater on for an overnight etch. Unfortunately, the water level reduced too much and the red warning light saying 'SAFETY CONTROL ACTIVATED' is now on. I don't know how to reset this alarm and the procedures involved. I have rinsed the bath, aspirated it and disabled the wet bench for now.
