If the tightening torque is insufficient, the product can be displaced and loosen the mounting screws.
(Refer to "Mounting and Installation" on page 14.)

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 35 N 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 apply excessive pressure to the piping port.

The product detects very small pressure. Do not apply pressure in excess of the proof pressure.

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 Pressure switch 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.

Wiring has to be less than 10 m.
Wire the DC(-) line(blue) as close as possible to the power supply.

When analogue output is used, install a noise filter (line noise filter, ferrite element, etc.) between the

switch-mode power supply and this product.

Environment

Do not use the product in area that is exposed to corrosive gases, chemicals, sea water, water or steam.

Otherwise failure or malfunction can result.

No.PS※※-OMV1001

Do not use in a place where the product could be splashed by oil or chemicals.

If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent, 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 should be 0 to 50 °C. Operation under low temperature (5 °C 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.

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 analogue output of approximate 1% immediately after the power supply
is turned on, within 10 minutes.

Perform settings suitable for the operating conditions.

Incorrect setting can cause operation failure.
For details of each setting, refer to page 19 to 48 of this manual.

Do not touch the LCD during operation.

The display can vary due to static electricity.

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.

reaches the set value, to when the ON-OFF output actually begins working.
Delay time setting can prevent the output from chattering.

Digit (Minimum setting unit)

Shows how precisely the pressure can be displayed or set by the digital
Pressure switch. When 1 digit = 1 kPa, the pressure is given with an increment
of 1kPa, e.g., 1, 2, 3, …, 99, 100.

Digital filter

Function to add digital filtering to the fluctuation of pressure value. Smooth the fluctuation
of displayed value and analogue output for sharp start up or fall of the pressure.

■Wiring

○Connection

Connections should only be made with the power supply turned off.
Use a separate route for the Pressure switch wiring and any power or high voltage wiring. Otherwise,

malfunction may result due to noise.

Ensure that the FG terminal is connected to ground when using a commercially available switch-mode

power supply. When a switch-mode power supply is connected to the product, switching noise will be
superimposed and the 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
product, or by using a series power supply instead of a switch-mode power supply.

○Connector

Connecting/Disconnecting

When mounting the connector, insert it straight into the socket, holding the lever and connector body, and

push the connector until the lever hooks into the housing, and locks.

When removing the connector, press down the lever to release the hook from the housing and pull the

connector straight out.

Pressure Setting

■Measurement mode

The measurement mode is the condition where the pressure is detected and displayed, and the switch
function is operating.
This is the basic mode, and other modes should be selected for setting changes and other function settings.

Setting the ON and OFF points of the Pressure switch.
Operation
When the pressure exceeds a set point, the Pressure switch will be turned ON.
When the pressure falls below the set point by the amount of hysteresis or more, the Pressure switch will be
turned OFF.
The default setting of the output set value is the central value between the atmospheric pressure and the
upper limit of the rated pressure range.
If this condition, shown below, is acceptable, then keep these settings.
