It must allow machine actuation as soon as the operator touches the handle, relying on warning sirens to alert nearby personnel. It must remain locked in the closed position until the hazardous machine movement has completely ceased, preventing hazardous startup while open. It must automatically deactivate all emergency stop circuits whenever maintenance personnel bypass the optical sensors. It must operate exclusively on single-channel unmonitored electromechanical relays without positive opening contacts.
