In this video I install and test the safety features. A lot of the original plan to have the safety relay in the show controller has changed and instead turned into a separate project, with building a soft start safety box that receives a special emergency signal from the controller.
A encoded signal (666 Hz) is sent over fiber optical link to a soft start safety box (bandpass filter from 400 to 1100 Hz) where a industrial grade safety class circuit is made to cut off mains supply to the Tesla coils in case of a malfunction in the monitored circuit or a pressed emergency stop.

I am building a Tesla coil show controller that can control up to 6 Tesla coils at once. It will feature individual interrupters, touch screen controlled MIDI interrupter, safety features to ensure a safe method of working with the Tesla coils before a show, under a show and after a show. It will all be housed in a transportable 19″ rack mount flight case for ease of transportation and to protect the electronics. The 6 channel MIDI interrupter is the feature rich Syntherrupter made by Max Zuidberg. He shares all the plans, documentation, code and schematics on: https://highvoltageforum.net/index.php?topic=1020.0
