Note: If the contactor is stuck in the ON position, the motor will not stop when the pad is in the ON position. Figure 16 shows the application connection diagram example of two contactors and contactor monitoring (dual channel) 440F-4000P and 440F-C4000S. Circuit status - power on - not present on sensor pad - reset button operated (if in manual reset mode) - machine start circuit enabled. Note: If any contactor is stuck in the ON position, the motor will stop and a fault will be detected when the pad is placed on it.

If the value changes, the safety distance calculation needs to be repeated. Next consider the reset option. Under normal and fault conditions, the consequences of the selected reset scheme should be carefully considered to prevent the danger caused by accidental startup, etc. The time sequence diagrams of the two modes of the cushion subsystem are given below. Fig. 19 Manual reset mode Fig. 20 Relationship between automatic reset mode drive, reset and output. The relationship between the start and output manual reset modes can be reset via a button or remote button on the control unit or a voltage free contact in the machine safety related control system. The output of the system will remain closed until reset after power on, and the master/slave reset circuit may be required in complex systems with other power on interlocks (start interlocks). Automatic reset mode When used in the automatic reset mode, the control system of the machine will need a separate reset function to prevent the machine from starting after leaving the mat or after a temporary power failure or drop.
