Specific Warnings
When mounting connector parts, comply with the
instructions issued by each connector manufacturer.
Loose connections may result in disconnection or
chemical leakage. The use of dangerous chemicals,
solvents, and gases may cause physical impairment.
Do not use the product in areas where corrosive gases are
being ejected. Corrosion in the pressure sensor and
connector may result in liquid leakage. The use of
dangerous chemicals, solvents, and gases may cause
physical impairment.
Obey these instructions.
- Refrain from excessive tightening of the connector parts.
- Do not install the product in areas of excessive vibration
or shock.
- Use the product only within the specified operating
environment. Otherwise, damage to the pressure sensor
and connector may occur and result in liquid leakage.
The use of dangerous chemicals, solvents, and gases
may cause physical impairment.
Protect all wiring used by providing support along the
wiring at appropriate distances.
For shielded cables, peel the sheath at the very end of the
cable and connect the shield to the chassis or mounting
plate, etc., using the proper tool (recommended tool: Nitto
Supply AL-2).
WARNING
This product is not explosion-proof. Never use it with
flammable fluids such as solvents. Doing so may cause
fire and or explosion and is highly dangerous.
Never disassemble or alter the product.
Doing so will cause breakage of the product and possible
liquid leakage. The use of dangerous chemicals, solvents,
and gases may cause physical impairment.
Do not apply more pressure than the allowed maximum
output. Doing so will cause product failure and possible
liquid leakage. The use of dangerous chemicals, solvents,
and gases may cause physical impairment.
Do not insert screwdrivers, wires, or other objects into the
connector parts. Doing so will cause product failure and
possible liquid leakage. The use of dangerous chemicals,
solvents, and gases may cause physical impairment.
Refrain from excessive pulling or bending of the cables.
Doing so may cause wiring disconnections, which may
cause electrical shock and fire hazards.
Install the pressure sensor in an area that is dry and
clean. Supply power to the pressure sensor from an
isolation transformer (switching power supply) rated for 24
VDC or less. Make sure the rated power output is 150 VA
and does not exceed 2A. (Use exclusively for class 2
circuits)

Mounting and Connecting the Connector Parts
When connecting the connector parts, clamp the sides of the body (WAF: 32 mm) with the dedicated tool
for the connector, and tighten the connector while preventing the body from turning.
In order to install connector parts correctly, always refer to the relevant catalog or operation manual issued
by the connector manufacturer.
Points to Observe When Installing
To prevent erroneous operation or premature wear, do not install in:
When mounting connector parts, comply with the instructions issued by each
connector manufacturer. Loose connections may result in disconnection or
chemical leakage. The use of dangerous chemicals, solvents, and gases
may cause physical impairment.
Refrain from excessive tightening of the connector parts. Otherwise, damage
to the pressure sensor and connector may occur and result in liquid leakage.
The use of dangerous chemicals, solvents, and gases may cause physical
im
p
airment.

Wiring
Observe these precautions to connect the leads correctly.
<Pressure sensor wiring diagram>
How to Use
Check the following items before using your Pressure Sensor.
(1) Make the Pressure Sensor open to the atmosphere (0kPa) and apply the power.
(2) Warm up your equipment by running “on empty” for approximately 20 minutes after power-on.
(3) Check to see that the externally displayed pressure and analog output values are as shown below.
(4) If the externally displayed pressure or analog output values are not as shown below, you will need to
do zero adjust following the instructions in “How to Do Zero Adjust”.
Never do wiring work when power supply is on. Doing so may cause electrical shock.
Do not pull or bend the cable forcibly. It may cause breakage of the cable, electrical shock, or fire. In
addition, pulling the cable forcibly rotates the case, which may result in the damage to the product.
Make sure to connect all leads correctly. Failure to do so may cause the product to fail.
If you are using a commercially available switching regulator as a power supply, always ground it to an
F.G. terminal. If electricity leaks to earth, it may cause electrical shock.
Connect the shield on shielded cables to the frame ground as necessary.

How to Do Zero Adjust
(1) Make sure that your Pressure Sensor is opened to the atmospheric state.
(2) Short circuit the Zero Adjust input signal for at least three seconds.
- When zero adjust starts, the zero adjust output alternates ON/OFF every 0.2 seconds.
- Zero adjust begins when the Zero Adjust input is opened.
(3) When zero adjustments is complete, the zero adjustment output transistor activate (short the output
signal to 0V) and resume measurement mode.
[Zero adjust error]
If the zero adjust output keeps alternating ON/OFF after at least three seconds from the time zero adjust
started, it is the indication of a zero adjust error.
- When zero adjust is in progress, an error will occur if the pressure in your piping system fluctuates
by ±1% F.S. or more.
- To reset the error, short circuit the zero adjust input for at least one second.
After the error resets, redo the zero adjust procedure from Step (1).
Zero adjust conditions:
- Open to the atmospheric state
- Pressure fluctuation must be within ±1% F.S.
Periodically provide the ZERO point adjustment.
Before doing the zero adjust procedure, Pressure Sensor is
opened to the atmospheric state.

Maintenance and Inspection
The Pressure Sensor should be inspected regularly, about twice a year depending on the usage.
During the regular inspection, check the
- appearance
- corrosion, clogging, leakage, etc., from the connector parts.
The Pressure Sensor should be flushed periodically if using liquids that crystallize easily.
<Safety Notes on Maintenance and Inspection>
In Case of Breakdown
Symptom Cause Countermeasure
Does not power up
(LED lamp does not light
up.)
Incorrect wiring. Check the wiring diagram and correct the
wiring.
Incompatible power, voltage. Check the power supply and voltage.
The externally displayed
pressure value does not
reach 0 kPa.
The equipment has not been
warmed up. Warm up the equipment for at least 20 minutes.
Zero point is off. Adjust the zero point.
Zero adjust fails. The pressure inside your
piping system is fluctuating. Vent the piping system to atmospheric state.
Incorrect wiring. Check the wiring diagram and correct the
wiring.
The LED does not change
from flashing to lit condition.
During the zero adjust
process, the pressure in your
piping system fluctuated by
±1% F.S. or more.
Short circuit the zero tracking input for 1 or
more second to reset the error. Adjust the
pressure in your piping so that it fluctuates less
than ±1% F.S. Then repeat zero adjust.
No analog output. Incorrect wiring.Check the wiring diagram and correct the
wiring.
The analog output value is
unstable. There is noise-generating equipment nearby. Move the noise-generating equipment from the vicinity.
The shield wire is not
grounded. Ground the shield wire.
The pressure inside your
piping system is fluctuating. Stop the pressure inside your piping system from fluctuating.
Notify your nearest sales office for problems not listed above.
If using dangerous chemicals, solvents, gases, etc., make sure to wear protective, chemical
resistant gear (protective gloves, mask, and clothing) to protect your entire body. Ejected liquids
may result in physical impairment.
Before disconnecting this product from the piping system, make sure the line is depressurized.
Otherwise, the fluid inside will eject and may result in physical impairment.
When replacing parts, or when performing maintenance or inspection, turn off the switch, and
release the fluid inside the piping to depressurize the line. Otherwise, the fluid inside will eject and
may result in physical impairment.
DANGER unless these precautions are not obeyed!
