Y1, Y2
0 V Voltage on, no
evaluation of
the voltage
quality
24 V The yellow
LED always
signals the
presence of an
actuator
within range.
24 V The sensor
must be
adjusted
before the
distance to the
actuator
increases and
before the
safety outputs
are disabled,
thus stopping
the machine.
24 V After 30
minutes if the
error is not
rectified
0 V Refer to table
with flash
codes
0 V Sensor in
teaching mode
0 V 10 minutes
pause after re-
teaching
0 V Example: door
open; a door
in the safety
circuit
upstream is
also open.
0 V Example: door
closed, a door
in the safety
circuit
upstream is
open.
