Table 6.2:
Receiver, connection assignment
With three-beam receivers SSD4 is switched off; with two-beam SSD3 is also switched off.
Selection of the transmission channel
The polarity of the power supply from Pin2 and Pin7 determines the selected optical
transmission channel.
If +24V DC is present on Pin2 and 0V on Pin7, transmission channel 1 is selected. If 0V is
present on Pin2 and +24V DC on Pin7, transmission channel 2 is selected.
Note!
Be sure to select the same transmission channel for both, for Transmitter and Receiver.
For optimum shielding, cables where the shield is routed on the knurled nut of the
connecting cable socket must be used.
SSD and Dyn SSD switching outputs
Caution!
The safety output consists of the 1-channel SSDs, which provide the status of the
corresponding beams, and the Dyn SSD output shared for all beams. When no errors are
present, this delivers a symmetrical square-wave signal with 300 ms pulse width. This
dynamic signal must be monitored by the downstream control unit. If the Dyn SSD signal
remains static, the power-driven machinery must be switched off. Correct connection must
be checked with the machine's first startup!
