switch body and the
actuator is longer than the
specified operating distance
Sao (OFF→ON).
When using a high-code
- model, an actuator not
paired is detected.
1 Switch body is faulty.
The number of connectable
2 switch bodies (sub) is
exceeded.
The check input / check
output wiring is short
circuited or disconnected.
3 The check input / check
output wiring is not correct.
Two or more switch bodies
(standard) are connected.

Make sure that the distance
between the switch body and
the actuator within the
specification range.
Make the switch body detect the
paired actuator.
Replace the switch body.

to the maximum of 29 units.
Correctly wire the check input
(pink) and check output (gray)
lines according to the wiring
diagram.
