Mounting and Adjustment
Caution
(1) Do not drop or apply impact.
The auto switch may be damaged or malfunction if it is dropped, bumped or applied with excessive impact (1000 m/s
2
or more).
(2) Observe the required tightening torque for mounting an auto switch.
If an auto switch is tightened beyond the specified tightening torque, the auto switch, mounting screws, or
mounting
bracket may be damaged.
Tightening below the specified tightening torque will allow the auto switch to move out of position.
(3) Do not carry an actuator by the auto switch lead wire.
This may cause a broken lead wire or damage to the auto switch internal elements.
(4) Use only the screws installed in the auto switch body for mounting the auto switch.
If other screws are used, the auto switch may be damaged.
(5) Mount the auto switch at the centre of its operating range.
Auto switches should be mounted so that the most sensitive position is at the centre of the operating range.
Mounting the auto switch close to the edge of its operating range (close to the border of ON/OFF operation) may
cause unstable operation.
(The auto switch mounting positions shown in the actuator catalogue indicate the optimum position at the end of stroke).
Some actuator and cylinder series have their own setting methods. In such cases, follow the instructions given.
(6) Check and adjust the actual auto switch 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.
Wiring
Caution
(1) Check the insulation of the 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.
(2) 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.
(3) 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 auto switch increases the possibility of
disconnection.
Secure the lead wire to reduce any movement in the area where the lead wire connects with the auto switch.
The recommended bending radius is 40 to 80 mm.
(4) Be sure to confirm the load condition (e.g. connection and current value) before power is supplied.
