Installation & Maintenance Manual
Auto Switch (Solid State)
Series D-F6N/D-F6P/D-F6B
Read this manual before using this product.
For future reference, please keep this manual in a safe place.
This manual should be read in conjunction with the current catalogue.
1.1 General recommendation
These safety instructions are intended to prevent a hazardous
situation and/or equipment damage.
These instructions indicate the level of potential hazard by label of
"Caution", "Warning" or "Danger".
To ensure safety of personnel and equipment the safety instructions in
this manual and the product catalogue must be observed, along with
other relevant safety practices.
Operator error could result in injury or
equipment damage.
Operator error could result in serious injury
or loss of life.
In extreme conditions, there is a possible
result of serious injury or loss of life.
Design and selection
Confirm the specifications.
Read the specifications carefully and use this product appropriately. The
product may be damaged or malfunction if it is used outside the range of
specifications for load current, voltage, temperature or impact.
Take precautions when multiple actuators are used close together.
When multiple auto switch actuators are used in close proximity,
magnetic field interference may cause the switches to malfunction.
Maintain a minimum actuator separation of 40mm.
Pay attention to the length of time that a switch is ON at an
intermediate stroke position.
When an auto switch is placed at an intermediate position of the stroke and
a load is driven at the time the piston passes, the auto switch will operate,
but if the speed is too great the operating time will be shortened and the
load may not operate properly. The maximum detectable piston speed is:
Keep wiring as short as possible
Although longer wiring does not affect the function, please keep it to
100m or shorter
Do not use a load that generates surge voltage.
Although a zener diode for surge protection is connected at the output side of
a solid state auto switch, damage may still occur if the surge is applied
repeatedly. When a load such as a relay or solenoid which generates surge is
directly driven, use a type of switch with a built-in surge absorbing element.
Cautions for use in an interlock circuit
When an auto switch is used for an interlock signal requiring high reliability,
devise a double interlock system to avoid trouble by providing a mechanical
protection function, or by also using another switch (sensor) together with
the auto switch.
Also perform periodic maintenance and confirm proper operation.
Ensure sufficient clearance for maintenance activities.
When designing an application, be sure to allow sufficient clearance for
maintenance and inspections.
Mount / adjustment
Do not drop or bump.
Do not drop, bump or apply excessive impacts (1000m/s2or more for solid state
switches) while handling. Although the body of the switch may not be damaged,
the inside of the switch could be damaged and cause a malfunction.
Do not carry an actuator by the auto switch lead wires.
Never carry an actuator by its lead wires. This may not only cause broken
lead wires, but it may cause internal elements of the switch to be damaged
by the stress.
Mount switches using the proper tightening torque.
If a switch is tightened beyond the range of tightening torque, the mounting
screws, mounting brackets or switch may be damaged.
On the other hand, tightening below the range of tightening torque may
allow the switch to slip out of position.
Mount a switch at the center of the operating range.
Adjust the mounting position of an auto switch so that the piston stops at
the center of the operating range (the range in which a switch is ON).
(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 may be unstable.
Wiring
Avoid repeatedly bending or stretching lead wires.
Broken lead wires can result from wiring patterns which repeatedly apply
bending stress or stretching force to the lead wires.
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 a switch.
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.
Do not allow short circuit of loads.
All models of switches do not have built-in short circuit protection circuits.
Note that if a load is short circuited, the switch will be instantly damaged
because of excess current flow into the switch.
Avoid incorrect wiring
I f wiring is incorrect, the switches will be damaged.
When stripping the cable envelope, please pay attention to the
stripping direction.
Insulator might be split or hurt depending on the directions.
Operating environment
Do not use in an area where a magnetic field is generated.
Auto switches can malfunction or magnets inside actuators can become
demagnetized.
Do not use in an environment where the auto switch will be
continually exposed to water.
Although switches satisfy IEC standard IP67 construction ( IS C 0920:
watertight construction), avoid using switches in applications with continual
exposure to water splash or spray. Poor insulation or swelling of the potting
resin inside switches may cause malfunction.
Do not use in an environment with oil or chemicals.
Consult SMC if auto switches are to be used in an environment with coolant,
cleaning solvent, various oils or chemicals. If auto switches are used under
these conditions for even a short time, they may be adversely affected by
improper insulation, malfunction due to swelling of the potting resin, or
hardening of the lead wires.
Do not use in an environment with temperature cycles.
Consult SMC if switches are used where there are temperature cycles
other than normal air temperature changes, as there may be adverse
effects inside the switches.
Do not use in an area where surges are generated.
When there are units (solenoid type lifter, high frequency induction furnace,
motor, etc.) which generate a large amount of surge in the area around
actuators with solid state auto switches, this may cause deterioration or
damage to the switches. Avoid sources of surge generation and crossed lines.

Avoid accumulation of iron waste or close contact with magnetic
substances.
When a large amount of iron waste such as machining chips or spatter has
accumulated, or a magnetic substance (something attracted by a magnet) is
brought into close proximity with an auto switch actuator, it may cause auto
switches to malfunction due to a loss of the magnetic force inside the
actuator.
Maintenance
Perform the following maintenance periodically in order to prevent
possible danger due to unexpected auto switch malfunction.
1) Securely tighten switch mounting screws.
If screws become loose or the mounting position is dislocated,
retighten them after readjusting the mounting position.
2) Confirm that there is no damage to lead wires.
To prevent faulty insulation, replace switches or repair lead wires,
etc., if damage is discovered.
