Here's the internal connections of the controller blocks.
In this simulation I'm using a shift register to implement the fail-safe counter. However I think in a real circuit a 555 timer could be used instead. Falling edge on "Enable" clocks the output D-flip flops and transfers the 4017 count value to the outputs.
