    Yep I think you have, although on my machines i always make the Estop ring as normaly closed ie you break the loop to Impose a condition, the reason for this is if a wire or connection breaks or the power fails or a component fails it will always break the circuit, showing an alarm condition. so all respective relays are energised giving closed condition for normal. this basicly gives me a circuit that is broken in the event of component failure or activation. the other way would not alarm in the event of a broken wire or failed component.

    Remember to check it with the Gurus though..
