7.4 Safety-sensors with serial diagnostic function
Safety sensors with serial diagnostic cable have a serial input and output instead of the conventional diagnostic
output. If RSS / CSS safety sensors are wired in series, the safety channels as well as the inputs and outputs of the

the presence
of an actuator
within range.

The sensor
must be
adjusted
before the
distance to the
actuator
increases and
before the
safety outputs
are disabled,
thus stopping
the machine.
