4.2 TRADITIONAL PHOTOCELLS
If the FAIL-SAFE safety device is not
used, connect the power supply of the
transmitters to terminals 6 and 8 of J13.
If the FAIL-SAFE safety device is used, connect
the power supply of the transmitters to OUT
after setting it as appropriate (see 2nd
level programming and Fig. 6).
If the FAIL-SAFE safety device is used, even the
unused safety inputs must be connected via a
shunt lead to the negative of OUT (see Fig. 6).
