• Check the product regularly for proper operation
Otherwise malfunction can result, causing an accident.

The following instructions must be followed during maintenance:

• Turn off the power supply

• Stop the air supply, exhaust the residual pressure and verify that the air is released before performing
maintenance.

Otherwise an injury can result.

After maintenance is complete, perform appropriate functional inspections and leak tests.

Stop operation if the equipment does not function properly or there is a leakage of fluid.
When leakage occurs from parts other than the piping, the product might be faulty.
Disconnect the power supply and stop the fluid supply.
Do not apply fluid under leaking conditions.

Installation

M

ounting

Mount the optional bracket and panel mount adapter to the pressure switch.
When the pressure switch is to be mounted in a place where water and dust
splashes occur, insert a tube into the air-relieving port of the pressure switch.
(Refer to "Tube attachment")

Mounting with bracket

Fix the bracket to the pressure switch with the set screws M3x5L (2 pcs.) or
M4x5L (2 pcs.) supplied.
Apply a tightening torque of 0.5 to 0.7 Nm for the M3 set screws or 1.4 to

1.6 Nm for the M4 set screws .

Piping

Connection using screw type piping

Connect suitable piping to the mating port.
Hold the hexagon part of the pressure port
and fix. Apply a tightening torque of 7 to 9 Nm.
When using an M5 female fitting
confirm the fitting specification.

Connection using One-touch fitting

1. Cut the tube perpendicularly.

2. Hold the tube and insert it into the
One-touch ftting slowly until it
bottoms out.

Allow sufficient tube length to prevent twist,
tensile and moment load from being applied
to the fitting and tube.
When using a tube manufactured by a
company other than SMC, check its outside
diameter accuracy satisfies the following values.

1) Nylon tube: ±0.1 mm at maximum

2) Soft nylon tube:

±0.1 mm at maximum

3) Polyurethane tube: +0.15 mm/-0.2 mm at maximum

Tube attachment

When this pressure switch is used
in a place where water and dust
splashes may occur, insert a tube in the
air-relieving port, and bring piping
of the opposite side up to the safe
position to keep it from water and
dust. (See the right figure.)

∗: The tube should be inserted to the end of the air-relieving port.
∗: SMC TU0425 (polyurethane, O.D ø4, I.D ø2.5) is a suitable tubing.

Wiring

Connection

Make connection after turning the power off.
Use a separate route when connecting the wire of
the Pressure switch.
Malfunction stemming from noise may occur if the
wire is installed in the same route as that of power
or high-voltage cable.
Be sure to ground terminal FG when using a

commerically available switch-mode power supply.
When the switch-mode power supply is connected to the Pressure switch,
switching noise wil be superimposed and product specification can no
longer be met. This can be prevented by inserting a noise filter, such as a
line noise filter and ferrite core, between the switch-mode power supply and
the Pressure switch, or by using a series power supply instead of the
switch-mode power supply.

Maintenance

How to reset the product after power cut or forcible de-energizing

The setting of the product will be retained as it was before a power cut or
de-energizing.
The output condition is also basically recovered to that before a power cut or
de-energizing, but may change depending on the operating environment.
Therefore, check the safety of the whole facility before operating the product. If the
facility is using accurate control, wait until the pressure switch has warmed up.
(About 10 to 15 minutes)

∗: Some functions are not available depending on part number. All functions are displayed with

[F ] and followed with function description. If a function is not available for specified type, the
function is displayed as [---].
