(8) Use the rotary actuator and auto switch in proper combination.
The auto switch is pre-adjusted to operate properly for an auto-switch-capable SMC rotary actuator.
If the auto switch is mounted improperly, used for another brand of rotary actuator or used after
changing the machine installation, the auto switch may not operate properly.
Mounting / Adjustment
Caution
(1) Do not drop or bump.
Do not drop, bump or apply excessive impacts (300m/s
1000m/s 2 or more for solid state auto switches) while handling. Although the body of the auto
switch may not be damaged, the inside of the auto switch could be damaged and cause
malfunction.
(2) Observe the proper tightening torque for mounting an auto switch.
When an auto switch is tightened beyond the range of tightening torque, auto switch mounting
screws, auto switch mounting brackets or auto switch may be damaged.
On the other hand, tightening below the range of tightening torque may allow the auto switch to
slip out of position.
(3) Do not carry a rotary actuator by the auto switch lead wires.
Never carry a rotary actuator by its lead wires. This may not only cause broken lead wires, but it
may cause internal elements of the auto switch to be damaged by the stress.
(4) Fix the auto switch using the appropriate screws on the switch body. If other screws are
used, the auto switch may be damaged.
Wiring
Caution
(1) Confirm proper insulation of wiring.
If there is any improper insulation (mixed contact with other circuits, grounding faults, improper
insulation between terminals, etc.) in the wiring, an over-current may flow in, causing the auto
switch to break.
(2) Wire separately from power lines or highvoltage lines, avoiding parallel wiring or wiring
in the same conduit with these lines.
If an inrush current is generated, the noise may cause the auto switch to malfunction.
(3) Avoid repeatedly bending or stretching lead wires.
Broken lead wires will result from repeatedly applying bending stress or stretching forces to the
lead wires.
Stress and tensile force applied to the connection between the lead wire and auto switch
increases the possibility of disconnection.
Keep the lead wire from moving, especially in the area where it connects with the auto switch.
