4.3 Wiring
Caution
• Do not perform wiring while the power is on.
• Confirm proper insulation of wiring.
Check that there is no faulty wiring insulation (short circuits, faulty
ground connections, improper insulation between terminals, etc.), as
this may damage the auto switch due to over current.
• Do not route the auto switch wiring in the same place as power cables
or high voltage cables.
Otherwise auto switch malfunction may result due to noise and inrush
current.
• Avoid repeatedly bending or stretching the lead wire.
Broken lead wires will result if bending stresses or tensile forces are
applied to the lead wires.
Stress and tensile forces applied to the connection between the lead
wire and the product increases the possibility of disconnection.
Secure the lead wire to reduce any movement in the area where the
lead wire connects with the position sensor.
• Do not allow short-circuit of loads.
There is a risk of damage of position sensor.
• Keep wiring as short as possible to prevent interference from
electromagnetic noise and surge voltage. Do not use a cable longer
than 20 m.

• Teach pad setting procedure
NOTE: For teaching the measurement range, make sure that the piston
position is at the start point of the range.
Click the teach pad, and then click and hold down the teach pad.
• Teach Level 1 starts when the indicator LED flashes slowly.
NOTE: If the indicator LED does not flash and setting is not available,
wait for 3 seconds and double-click the teach pad again.

• IODD file
IODD (I/O Device Description) is a definition file which provides all
properties and parameters required for establishing functions and
communication of the device.
IODD includes the main IODD file and a set of image files such as vendor
logo, device picture and device icon.
The IODD file is shown below.
