Wiring of Output
■ S14, S24, S34, S44, S54 : P channel safety outputs
The instantaneous or off-delay safety outputs go to ON or OFF based on the safety
inputs, feedback start input, logic input, and input signals of non-contact door switch.
• Leave unused safety outputs in the OPEN state.
• Configure a protection circuit against the counter electromotive force when
connecting inductive loads.
• To expand the number of safety outputs in the form of contacts, connect the
expansion cable of the expansion relay unit to advanced unit or the expansion
connector of non-contact door switch unit, and connect the loop connector to the
expansion relay unit located at the end of position.
• Operation of safety output and safety off-delay output based on the safety input signal

■ 13/14, 23/24, 33/34 (37/38), 43/44 (47/48)
: Safety outputs of relay unit
The instantaneous or off-delay safety outputs go to ON or OFF based on the safety
inputs, feedback start input.
• Leave unused safety outputs in the OPEN state.
■ X1: Auxiliary output 1
When the instantaneous safety outputs are ON, the X1 auxiliary output goes to ON.
When the instantaneous safety outputs are OFF, the X1 also goes to OFF.
• Leave unused auxiliary output in the OPEN state.
■ X2: Auxiliary output 2
X2 auxiliary output goes to ON when the ERR indicator turns on or flashes.
• Leave unused auxiliary output in the OPEN state.
Error Indication
When an error occurs, the ERR indicator and other indicators turn on or flash to notice
the cause of error.
Be sure to check and take measures according to the table below, and turn the power
on again. If the measures are not valid, please contact the Autonics.

Check and measures
Check the supplied power voltage.
Check the wiring to M11, M12
terminal.
Please contact the Autonics.
Check the wiring to M21, M22
terminal.
Please contact the Autonics.
Check the wiring to M51, M52 and
M53 terminal.
Please contact the Autonics.
Check the supplied power voltage
to the expansion relay unit.
Check the cable of expansion
relay unit and loop connector
connection.
Please contact the Autonics.
Check the wiring to the D1 and
D2 terminal of non-contact door
switch.
Check the wiring to between the
non-contact door switches.
Replace the non-contact door
switch (SFN series).
Check the wiring to M61 and M62
terminal.
Check the setting values of SW1
and SW2 at switch for logic (AND)
input.
Please contact the Autonics.
Check the wiring to instantaneous
safety output terminal.
Please contact the Autonics.
Check the wiring to the off-delay
safety output terminal.
Please contact the Autonics.
Check the setting value of the
switch for off-delay time.
Please contact the Autonics.
Check the wiring to the safety
input devices. Check the input
sequence of safety inputs.
Check and Maintenance
■ Check installation conditions
Checklist
The distance from hazardous zone or source of the machine to the product,
safety sensors connected to the product, installed location is equal to or
1
greater than calculated safety distance.
Safety distance: ()mm / Actual distance: ()mm
Installed in the environment without the material causing deformation such as
2
corrosion or ignition.
When installing the DIN rail or panel, the product is firmly fixed to prevent
3
separation.
4
There is no product damage or appearance problem.
■ Check wiring connection
Checklist
The power supply used for devices related to the product and safety-related
1
functions is 24VDC, and a dedicated power supply meets the specified rated
specifications and is not connected to other devices or equipment.
2
When connecting power supply, the polarity is not connected in reverse.
The appearance of the wiring connected to the product is not damaged, such
3
as cracking, breakage, etc. of the outer shell, and there is no cause for damage
around the wiring.
In case of connecting more than two products, it is configured for the
4
dedicated series connection or mutual interference.
5
The wiring connected to the product is correctly connected to each purpose.
The wiring connected to the product is firmly fixed to prevent separation
6
during use.
In case of auxiliary output (AUX1,AUX2), it is configured to prevent the
7
connection to safety-related part of the control system.
■ Safety system-check in operation
Checklist
1
Inspect without operator in hazardous zone or near the source of hazard.
The safety input signal is off while the machine is operating, then the safety
2
system immediately stops.
In case of the power shut down, the safety system stops and maintains the
3
status.
