(single channel), 440F-C4000D. Circuit status - Supply power ON - No presence on sensor mat - Reset button operated (if in manual reset mode) - Machine start circuit enabled. NOTE: If the contactor sticks ON - the motor will not stop when the mat is stood on. Fig. 18 Example connection diagram showing application with two contactors and contactor monitoring (dual channel), 440F-C4000D. Circuit status - Supply power ON - No presence on sensor mat - Reset button operated (if in manual reset mode) - Machine start circuit enabled. NOTE: If either of the contactors stick ON - the motor will stop when the mat is stood on and the fault will be detected.

If the value changes, it will be necessary to repeat the safety distance calculations. Next consider the options for reset. The consequences of the reset scheme selected should be carefully considered for hazards caused by unexpected start up etc., both under normal conditions and under fault conditions. Timing diagrams are given below for both modes of the mat system. Fig 19 Manual reset mode Fig 20 Auto reset mode Relationship between actuation, reset and output. Relationship between actuation and output MANUAL RESET MODE The reset can be accomplished by the button on the control unit or by a remote push button or by voltage free contacts within the machine safety related control system. The outputs of system will remain off until reset after power up and may require master/slave reset circuits in complex systems where other power up interlocks (start interlocks) are present.
