Configuration of the device self-test

Fig. 5-6: Connection of the OSSD outputs in the device self-test
S = Sender
The device self-test is active when the test input (Test) of the sender is
connected to 24 V. The receiver permanently checks the switching
outputs OSSD 1 and OSSD 2 for signal identity.
Connect OSSD 1 and OSSD 2 separately!
In the device self-test both OSSD outputs must be connected! To ensure
signal safety, OSSD 1 and OSSD 2 must be connected separately to the
machine controller and the machine controller must process the two
signals separately.
OSSD 1 and OSSD 2 must not be interconnected.
Fig. 5-7: Never interconnect OSSD relays (= single channel)!
The two outputs are short-circuit-proof against 24 V DC and 0 V. When
the light path is free the signal level of the outputs is high; when the
light path is broken and in case of device error, low.
