Table 6.2:
With three-beam receivers, SSD4 is switched off; with two-beam, SSD3 is also switched off.
Selection of the transmission channel
The optical transmission channel can be selected by reversing the polarity of Pin2 and Pin7.
If +24 V DC is applied at Pin2 and 0 V at Pin7, transmission channel 1 is selected. If 0 V is applied at Pin2
and +24 V DC at Pin7, transmission channel 2 is selected.
NOTE
Be sure to select the same transmission channel for both, transmitter and receiver.
For optimum shielding, connection cables where the shield is routed on the housing connector must be
used.
SSD and Dyn SSD safety outputs
ATTENTION!
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 moni-
tored by the downstream control. If the Dyn SSD signal remains static, the power-driven
machinery must be switched off. Correct connection must be checked with the machine's initial
commissioning!
