Mounting / Adjustment
(1)
Do not drop or bump.
Do not drop, bump or apply excessive impacts (300m/s
2
or more for reed auto switches and 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
(1)
Confirm proper insulation of wiring.
Be certain that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation
between terminals, etc.). Damage may occur due to excess current flow into the auto switch.
(2)
Do not wire with power lines or high voltage lines.
Wire separately from power lines or high voltage lines, avoiding parallel wiring or wiring in the same conduit
with these lines. Control circuits containing auto switches may malfunction due to noise from these other lines.
(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 cable and auto switch increases the possibility
of disconnection.
Fix the cable in the middle so that it is not movable in the area where it connects with the auto switch.
(4)
Be certain to connect the load before power is applied.
<2-wire type>
If the power is turned ON when an auto switch is not connected to a load, the auto switch will be instantly
damaged because of excess current (Short circuit).
It is the same as when the 2-wire brown lead wire (+, output) is directly connected to the (+) power supply
terminal.
(5)
Do not allow short-circuit of loads.
<Reed>
If the power is turned ON with a load in a short circuit condition, the switch will be instantly damaged because
of excess current flow into the switch.
<Solid state>
PNP output type auto switches do not have built-in short circuit prevention circuits.
If a load is short circuited, the auto switch will be instantly damaged as in the case of reed auto switches.
Take special care to avoid reverse wiring with the brown power supply line and the black output line on 3-wire
type auto switches.
