Note that if the contactor is stuck in position, the motor will not stop when the pad is in position. Figure shows an example of an application connection diagram for two contactors and contactor monitoring dual channels and. Circuit status Power on Sensor pad does not have reset button operated If in manual reset mode machine start circuit is enabled. Note that 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.

Illustration shows an example connection diagram for two contactors and contactor monitoring dual channel applications. Circuit status Power on Sensor pad does not have reset button operated If in manual reset mode machine start circuit is enabled. Note that if any of the contactors is stuck in the ON position, the motor will stop when the pads are placed and a fault is detected. Power supply auxiliary output auxiliary input start instantaneous button stop instantaneous button fuse motor protection, for example. The thermal circuit breaker control unit guides forward the auxiliary contact of the contactor, white white black wind sensor pad, the internal sensor pad, the reset power supply, the standby power supply, the power supply, the auxiliary output, the auxiliary input, the auxiliary start instantaneous button, the stop instantaneous button, the fuse motor protection, for example. After the design of the safety related control system is completed, ensure that the response time assumed in remains valid. 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. Figure Manual reset mode Figure Relationship between automatic reset mode startup 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 it is reset after power on, and the master-slave reset circuit may be required in complex systems where 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.
