Three sensors and two contactors with manual reset and EDM (External Device Monitoring). Machine will start
when all guards are closed, reset button is pressed and then start button is pressed. NOTE: The use of multiple
sensors connected to a single control unit is only suitable in applications where each guard door is always
opened and then shut individually. Otherwise some single faults may not be detected and unintentional lockout
reset may occur if two or more guard doors are open at the same time.
