Single-channel assignment of safe relay outputs
For single-channel assignment, the safety relays operate independently of one another.
This means that they are controlled individually by the safe controller. It is possible to
monitor external loads and the wiring for errors. In this case, use a clock output (UT1 or
UT2) with the associated alarm input. Activate this function in the parameterization (IN1 or
IN2, see Section "Parameterization of the safe relay outputs" on page 5-2).
