Read this instruction manual carefully before using this product, particularly the section
describing safety.
Retain this instruction manual with the product for further consultation whenever necessary.
Precaution
● This product is designed for air / non-corrosive gas.
●
● Do not touch electric wiring connections (bare live parts): this will cause an electric shock.
During wiring, keep the power off. Also, do not touch these live parts with wet hands.
● A product intended for use in Japan conforms to the Japanese Measurement Act.
Do not use a product intended for use overseas in Japan.

Notes: 1) In the case of a model that is intended for use outside Japan, attach the unit switch plate corresponds to the set
pressure unit.
2) The product for use inside Japan can be set only to “MPa” or “kPa.”
2PIPING
● When connecting a commercial coupler to the pres-
sure port, attach a 12mm spanner (14mm for 6G
type) to the pressure port’s hexagon section to fix
the port, and then tighten with a tightening torque of
9.8N·m or less (M5 female: 1N·m or less). The com-
mercial coupler or pressure port section will be dam-
aged if the tightening torque is excessive.
Wrap sealing tape around the coupler when connect-
ing to prevent leaks.
12mm spanner
3MOUNTING
● The sensor mounting bracket PPX-KL is available as an option. When mounting the sensor
onto the sensor mounting bracket, etc., the tightening torque should be 0.5N·m or less.

closed with PPX-KHS.

Notes: 1) When the analogue current is output, the output load resistance should be 250Ω max.
2) Take care that when the analogue current is output, 5V or more voltage generates.
3) When using the analogue voltage output, be careful to the input impedance of the connected device.
Furthermore, note that if the cable is extended, the cable resistance will cause the voltage to drop.

10 SETTING COPY FUNCTION
● This can copy the settings of the master side sensor to the slave side sensor.
● Be sure to use the setting copy function between the identical models.
This function cannot be used between different models.
● Only one sensor can be connected on slave side with a master side sensor for the
setting copy function.
Setting procedure
1. Set the setting copy function of the master side sensor to “Copy sending ON” or
“Copy sending ON-L”, and then press the mode selection key so that the sensor is
in copy ready state. For details, refer to <Setting copy mode> in “ 9PRO MODE”.
2. Turn OFF the master side sensor.
3. Connect the master side sensor with the slave side sensor as shown below.

Notes: 1) For the high-function type, external input.
4. Turn ON the master side sensor and the slave side sensor at the same time.
(Note 2) (Note 3)
5. Set contents (16-bit coded) are shown in orange on the main display of the master
side sensor and the copying starts.
6. The same code explained above is shown in green on the the main display of the
slave side sensor, and “ ” is shown on the sub-display (When copying is com-
plete.)
7. Turn OFF the power of the master side sensor and the slave side sensor and dis-
connect the wire.
* If copying the setting to another sensor repeatedly, follow steps 3to 7.
Notes: 2) Take care that if the power is not turned on at the same time, the setting contents may not be copied.
3) Note that when the power is on, pulse output is output to comparative output 1.
To cancel the setting copy mode of master side sensor
1. Whilst the slave side sensor is disconnected, turn on the power of the master side
sensor.
2. Press the mode selection key for approx. 2 seconds.

11 AUTO-REFERENCE FUNCTION (ONLY HIGH-FUNCTION TYPE)
● The auto-reference function
corrects the set value using the
detected pressure value during
auto-reference input as the refer-
ence pressure.
● Using the detected pressure val-
ue at auto-reference input P(a)
as a reference, the set value 1’
is automatically corrected to “set
value 1+ P(a)”.

Set value 1’ after auto-reference is:

Settable range and set pressure range after correction
● The set pressure range is wider than the rating pressure range so that the auto-
reference function can be handled.
If the corrected set value exceeds the set pressure range when auto-reference input
is carried out, the set value will be automatically corrected to within the set pressure
range. Thus, take care not to exceed the set pressure range.

Note: The set values shift in the same manner during the EASY mode or the window comparator mode.
● The detected pressure value at auto-reference input becomes “zero” when the set-
ting of the external input selection function is changed or the power is turned ON
again.
● The auto-reference input value can be checked when setting the threshold value in
RUN mode. Refer to the threshold value setting in “ 7RUN MODE” for details.
12 REMOTE ZERO-ADJUSTMENT FUNCTION (HIGH-FUNCTION TYPE)
● The remote zero-adjustment function forcibly sets the pressure value to “zero” when
the external signal is inputted.
The set value is not corrected when remote zero-adjustment is input. Make sure that the
pressure and set value during remote zero-adjustment do not exceed the set pressure
range.

selection is changed or the power is turned ON again, and normal operation based
on the atmospheric pressure is resumed.
● The remote zero-adjustment value can be confirmed when setting the threshold
value in RUN mode. Refer to the threshold value setting in “ 7RUN MODE”.
13 ERROR INDICATION
Error message Cause Corrective action
The load is short-circuited causing Turn the power OFF and check the load.
Pressure is applied during zero-

atmospheric pressure and zero-point adjustment should be
done again.
External input is carried out outside
the rated pressure range.
Applied pressure range should be brought within the rated

● This product has been developed / produced for industrial use only.
● Use within the rated pressure range.
● Do not apply pressure exceeding the pressure withstandability value. The dia-
phragm will get damaged and correct operation shall not be maintained.
● Make sure that the power supply is off while wiring.
● Take care that wrong wiring will damage the sensor.
● Verify that the supply voltage variation is within the rating.
● If power is supplied from a commercial switching regulator, ensure that the frame
ground (F.G.) terminal of the power supply is connected to an actual ground.
● In case noise generating equipment (switching regulator, inverter motor, etc.) is
used in the vicinity of this sensor, connect the frame ground (F.G.) terminal of the
equipment to an actual ground.
● Do not use during the initial transient time (0.5 sec.) after the power supply is
switched on.
● Extension up to total 100m or less, is possible with more than 0.3mm2of electric
conductor cross-sectional area cable.
● In case of using this product as a CE Marking conformity product, the wire con-
nected to this product must be within 30m.
● Do not run the wires together with high-voltage lines or power lines or put them in
the same raceway. This can cause malfunction due to induction.
●
● Avoid dust, dirt, and steam.
● Take care that the sensor does not come in direct contact with water, oil, grease, or
organic solvents, such as, thinner, etc.
● Do not insert wires, etc, into the pressure port. The diaphragm will get damaged
and correct operation shall not be maintained.
● Do not operate the keys with pointed or sharp objects.
● Make sure that stress by forcible bend or pulling is not applied directly to the sensor
cable joint.
