The corresponding control unit is BG 5925/920. Block diagram Function Mounting différence y- The safety switch NE 5020 includes a magnetic coded transmitter and a receiver as decoder. The semiconductor outputs close, when the receiver recognises the right code from the transmitter. The control unit detects cross faults on the lines 14 and 24. The control unit is switched off when a fault is detected and inhibits a new start. The switch is protected against short circuits and peak voltages. Connections The NE 5020 is connected to the control unit BG 5925/920 according to the application example below. Indication green LED: switch is active, outputs switched on Notes The code of transmitter and receiver are identically on delivery. This can be verified by a mark on the test sticker.
