●Product handling
∗Installation
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws and brackets may be broken.
If the tightening torque is insufficient, the product can be displaced and loosen the mounting screws.
(Refer to "Mounting and Installation" on page 15.)
•Do not apply excessive stress to the product when it is mounted with a panel mount.
Otherwise damage to the product and disconnection from the panel mount can result.
•Be sure to ground terminal FG when using a commercially available switch-mode power supply.
•Do not drop, hit or apply shock to the Pressure switch.
Otherwise damage to the internal parts can result, causing malfunction.
•Do not pull the lead wire forcefully, not lift the product by pulling the lead wire. (Tensile force 49N or less)
Hold the body when handling to avoid the damage of the Pressure switch which lead to cause the failure and
malfunction.
•For piping of the Pressure switch, hold the piping with a spanner on the metal part of the piping (Piping
attachment).
Holding other part with spanner leads to damage the Pressure switch.
•Eliminate any dust left in the piping by air blow before connecting the piping to the product.
Otherwise it can cause damage or malfunction.
•Do not insert metal wires or other foreign matter into the pressure measurement port.
It can damage the pressure sensor causing failure or malfunction.
•Never mount a product in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
•If the entering of foreign material to the fluid is possible, install and pipe the filter or the mist separator to
the inlet to avoid failure and malfunction.
∗Wiring
•Do not pull the lead wires.
In particular, never lift a Pressure switch equipped with fitting and piping by holding the lead wires.
Otherwise damage to the internal parts can result, causing malfunction or to be off the connector.
•Avoid repeatedly bending or stretching the lead wire, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause the sheath of the wire to peel off, or breakage of the wire.
If the lead wire can move, fix it near the body of the product.
The recommended bend radius of the lead wire is 6 times the outside diameter of the sheath, or 33 times the
outside diameter of the insulation material, whichever is larger.
Replace the damaged lead wire with a new one.
•Wire correctly.
Incorrect wiring can break the Pressure switch.
•Do not perform wiring while the power is on.
Otherwise damage to the internal parts can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the product can malfunction due to interference of noise and surge voltage from power and high voltage
cables to the signal line. Route the wires (piping) of the product separately from power or high voltage cables.
•Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
•Design the system to prevent reverse current when the product is forced to operate for operational
check.
Depending on the circuit used, insulation may not be maintained when operation is forced, allowing reverse current
to flow, which can cause malfunction and damage the product.
•Keep wiring as short as possible to prevent interference from electromagnetic noise and surge voltage.
Do not use a cable longer than 10m.
Wire the DC (-) line (blue) as close as possible to the power supply.
•When analog output is used, install a noise filter (line noise filter, ferrite element, etc.) between the
switch-mode power supply and this product.

even for a short time, it may be adversely affected (damage, malfunction, or hardening of the lead wires)
•Do not use in an area where surges are generated.
If there is equipment which generates a large amount of surge (solenoid type lifter, high frequency induction
furnace, motor, etc.) close to the Pressure switch, this may cause deterioration or breakage of the internal circuit of
the Pressure switch. Avoid sources of surge generation and crossed lines.
•Do not use a load which generates surge voltage.
When a surge-generating load such as a relay or solenoid is driven directly, use a Pressure switch with a built-in
surge absorbing element.
•The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes
in the system.
•Mount the product in a place that is not exposed to vibration or impact.
Otherwise failure or malfunction can result.
•Prevent foreign matter such as remnant of wires from entering the Pressure switch.
Take proper measures for the remnant not to enter the Pressure switch in order to prevent failure or malfunction.
•Do not use the product in an environment that is exposed to temperature cycle.
Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.
•Do not expose the product to direct sunlight.
If using in a location directly exposed to sunlight, shade the product from the sunlight.
Otherwise failure or malfunction can result.
•Keep within the specified fluid and ambient temperatures range.
The fluid and ambient temperatures is 5 to 50 oC. Operation under low temperature (5 oC or less) leads to cause
damage or operation failure due to frozen moist in the fluid or air.
Protection against freezing is necessary. Air dryer is recommended for elimination of drain and water.
Avoid sudden temperature change even within specified temperature.
•Do not operate close to a heat source, or in a location exposed to radiant heat.
Otherwise malfunction can result.
•Use operating fluid which does not corrode the part in contact with fluid which is made of SUS630 (for
sensing part) or SUS304 (for fitting part).
(Compatibility between fluid and material can be checked by contact to fluid supplier.)
∗Adjustment and Operation
•Turn the power on after connecting a load.
Otherwise it can cause excess current causing instantaneous breakage of the Pressure switch.
•Do not short-circuit the load.
Although error is displayed when the Pressure switch load is short circuit, generated excess current lead to cause
the damage of the Pressure switch.
•Do not press the setting buttons with a sharp pointed object.
It may damage the setting buttons.
•If using the product to detect very small pressure rates, warm up the product for 10 to 15 minutes first.
There will be a drift on the display and the analog output of approximate 1% immediately after the power supply is
turned on.
•Perform settings suitable for the operating conditions.
Incorrect setting can cause operation failure.
For details of each setting, refer to page 21 to 43 of this manual.
•The Pressure switch is compulsory turned off for 4 seconds after power supplied.

PS##-OMM0003-A
∗Maintenance
•Turn off the power supply, stop the supplied air, exhaust the residual pressure and verify the release of
air before performing maintenance.
There is a risk of unexpected malfunction.
•Perform regular maintenance and inspections.
There is a risk of unexpected malfunction.
•Perform drainage regularly.
If condensate enters the secondary side, it can cause operating failure of pneumatic equipment.
•Do not use solvents such as benzene, thinner etc. to clean the Pressure switch.
They could damage the surface of the body and erase the markings on the body.
Use a soft cloth to remove stains. For heavy stains, use a cloth soaked with diluted neutral detergent and fully
squeezed, then wipe up the stains again with a dry cloth.
∗Other
•If there is a possibility of water or drainage getting in, narrow the diameter of the piping to the Pressure
switch, or make an orifice in the middle of the piping.
Although this Pressure switch uses stainless diaphragm pressure sensor which is not damaged by water, the drain
contained in the air or water during vacuum release after confirming vacuuming collides with the pressure sensor
and the inertia force of water or air containing the drain can damage the pressure sensor, and correct display of the
pressure may not be available.
Extra attention is needed when the rear surface piping type is used.
•The use of a resin piping can cause static electricity depending on the fluid.
Therefore, when connecting the Pressure switch, take appropriate measures against static electricity
and separate the grounding for the Pressure switch from the grounding for other equipment which may
generate a strong electromagnetic noise or high frequency.
Otherwise, static electricity may damage the Pressure switch.
