Description

4 Installation

4.1 Installation

Warning

• Do not install the product unless the safety instructions have been read
and understood.

• Use the product within the specified operating pressure and
temperature range.

• When mounting an actuator position sensor, use a mounting bracket
appropriate for the cylinder/actuator.

• The mounting method differs according to the type of actuator and the
inner diameter of the tube.

• When mounting a sensor for the first time, check that the
cylinder/actuator has a built-in magnet and use an appropriate bracket
for the cylinder/actuator. There are also cases when a bracket is not
needed.

• Use the correct tightening torque
When tightening mounting screws, use a suitable hexagon wrench
(size 1.5). Recommended torque should be 0.2 to 0.4 Nm.
Over-tightening can damage the cylinder/actuator and sensor.
Loose screws can cause misalignment or a reduction in accuracy
during operation. Tightening below the specified tightening torque will
allow the position sensor to move out of position.

• Do not carry an actuator by the position sensor lead wire.

• This may cause a broken lead wires or damage to the auto switch

internal elements.

• Use only the screws installed in the position sensor body for mounting
the position sensor.

If other screws are used, the position sensor may be damaged.

• Check and adjust the actual product operation during installation.
The auto switch may not operate in the correct actuator mounting
position due to the installation environment. Also check and adjust the
auto switch operation when used in intermediate stroke positions,
according to the operating environment.

• Press the switch down into the cylinder/actuator switch mounting
groove as shown.

• Tighten the mounting screws evenly.

4.2 Environment

Warning

• Do not use in an environment where corrosive gases, condensation,
chemicals, salt water or steam are present.

• Do not use in an explosive atmosphere.

• Do not expose to direct sunlight. Use a suitable protective cover.

• Do not install in a location subject to vibration or impact in excess of

the product’s specifications.

• Do not mount in a location exposed to radiant heat that would result in
temperatures in excess of the product’s specifications.

• Do not use in a location where magnetic fields are generated.

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.
