Mounting / Adjustment
1. Do not drop or bump.
Do not drop, bump or apply excessive impacts (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.
This may cause disconnection of the lead wire or the internal element to break.
4. Do not use screws other than the set screws installed on the auto switch body to secure the
auto switch.
If using other screws, auto switch may be damaged.
5. Mount an auto switch at the center of the operating range.
In the case of 2-color display auto switch, mount it at the center of the green LED illuminating range.
Adjust the mounting position of the auto switch so that the piston stops at the center of the operating
range. (The mounting position shown in the catalog indicates the optimum position at stroke end.)
If mounted at the end of the operating range (around the borderline of ON and OFF), operation will be
unstable depending of the operating environment. Also there are some rotary tables with individual
setting methods for auto switches. If so, mount it in accordance with the indicated method.
6. Check the actual actuation status and adjust the auto switch mounting position.
According to the installation environment, the rotary actuator may not operate even at its proper
mounting position. Even when setting at a midpoint of the stroke, check the actuation status and make
the adjustment in the same manner.
7. Be very careful when handling the auto switch mounting band, as it has a thin structure.
Wiring
1. Confirm proper insulation of wiring.
If there is any improper insulation (mixed contact with other circuit, grounding fault, or improper
insulation between terminals, etc.) in the wiring, an over-current flows in, causing the auto switch to
break.
-13-
Even if 2-color indication solid state auto switches are fixed at a proper operating
range (the green light lights up), the operation may become unstable depending
on the installation environment or magnetic field disturbance.
Magnetic body, external magnetic field, proximal installation of rotary actuator
with built-in magnet and actuators, temperature change, other factors for
magnetic force fluctuation during operation, etc.
