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 less than 30 m.

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.
When the Pressure switch is used in a place which is exposed to the splash of oil and solvent all the
time, protect the Pressure switch from direct splash.
It can corrode and swell the seal (FKM, HNBR) which causes the malfunction of the Pressure switch.
Adjustment and Operation
Turn the power on after connecting a load.
Otherwise it can cause excess current causing instantaneous breakage of the Pressure switch.

Outline of Settings [Measurement mode]
Power is supplied
The product code is displayed for approximately 3 seconds after power is supplied.
Then, measurement mode will be displayed.
: Within approximately 0.2 seconds after power-on, the switch starts.
[Measurement mode]
Detects the pressure after power is supplied, and indicates the display and switch operating status.
This is the basic mode; other modes should be selected for set-point changes and other function
settings.

Pressure Setting
Default settings
When the pressure exceeds the set value, the switch will be turned on. When the pressure falls below the set
value by the amount of hysteresis or more, the switch will be turned off. The default setting is to turn on the
pressure switch when the pressure reaches the center of the atmospheric pressure and upper limit of the
rated pressure range. If this condition, shown to the below, is acceptable, then keep these settings.

3-Step Setting Mode
3 step setting mode
In this mode, the set values can be input in just 3 steps.
Use this mode if the product is to be used straight away, after changing only the set values.
(The current pressure value is displayed on the main display.)
<Operation>
[3 step setting mode (hysteresis mode)]
In the 3 step setting mode, the set value (P_1 or n_1) and hysteresis (H_1) can be changed. Set the items
on the sub display (set value or hysteresis) with the UP or DOWN button. When changing the set value,
follow the operation below. The hysteresis setting can be changed in the same way.
(1) Press the SET button once when the item to be changed is displayed on the sub display.
The set value on the sub display (right) will start flashing.
(2) Press the UP or DOWN button to change the set value.
The set value can be increased with the UP button and can be reduced with the DOWN button.
●Press the UP button once to increase the value by one digit, press and hold to continuously increase.
●Press the DOWN button once to reduce the value by one digit, press and hold to continuously
reduce.
●When the UP and DOWN buttons are pressed and held simultaneously for 1 second or longer, the
set value is displayed as [- - -], and the set value will be the same as the current pressure value
automatically (snap shot function (Refer to page 55.)). Afterwards, it is possible to adjust the value by
pressing the UP or DOWN button.
(3) Press the SET button to complete the setting.

The Pressure switch turns on within a set pressure range (from P1L to P1H) during window comparator
mode. Set P1L, the lower limit of the switch operation, and P1H, the upper limit of the switch operation and
WH1 (hysteresis) following the instructions given on page 21.
(When reversed output is selected, the sub display (left) shows [n1L] and [n1H].)
Please refer to the "List of output modes" on page 31 for the relationship between the set values and
operation.
: Set OUT2 in the same way.
Setting of the normal/reverse output switching and hysteresis/window comparator mode switching are performed with the function
selection mode [F 1] OUT1 setting and [F 2] OUT2 setting.

Simple Setting Mode
<Operation>
[Simple setting mode (hysteresis mode)
In the simple setting mode, the set value, hysteresis and delay time can be changed while checking the
current pressure value (main display).
(1) Press and hold the SET button between 1 and 3 seconds in measurement mode. [SEt] is displayed on
the main display. When the button is released while in the [SEt] display, the current pressure value is
displayed on the main display, [P_1] or [n_1] is displayed on the sub display (left), and the set value is
displayed on the sub display (right) (Flashing).
(2) Change the set value with the UP or DOWN button, and press the SET button to set the value. Then,
the setting moves to hysteresis setting. (The snap shot function can be used. (Refer to page 55.))
(3) Change the set value with the UP or DOWN button, and press the SET button to set the value. Then,
the setting moves to the delay time of the switch output.
(The snap shot function can be used. (Refer to page 55.))
(4) The delay time of the switch output can be selected by pressing the UP or DOWN button at the ON and
OFF point of the switch output.
Delay time setting can prevent the output from chattering.
The delay time can be set in the range 0.00 to 60.00 sec. in 0.01 sec. increments.
(5) Press the SET button for less than 2 seconds to complete the OUT1 setting.
[P_2] or [n_2] is displayed on the sub screen (left). Continue with setting the OUT2.
Press and hold the SET
button for 2 seconds or longer to complete the setting. The product will return
to measurement mode.
1: Selected items (1) to (4) become valid after pressing the SER button.
2: After enabling the setting by pressing the SET button, it is possible to return to measurement mode by pressing the SET
button for 2 seconds or longer.
3: When the output mode (refer to page 29) is set to error output or output OFF, the simple setting mode cannot be used.
(The setting changes to measurement mode by releasing the button when [SEt] is displayed.)
