ISO 10218-1: Robots and robotic devices - Safety requirements for industrial robots - Part 1:Robots
etc.
Danger Danger indicates a hazard with a high level of risk which, if not avoided, will result
in death or serious injury.
Warning
Warning indicates a hazard with a medium level of risk which, if not avoided, could
result in death or serious injury.
Caution
Caution indicates a hazard with a low level of risk which, if not avoided, could result
in minor or moderate injury.
Warning
1. The
compatibility of the product is the responsibility of the
person who designs the equipment

Since the product specified here is used under various operating conditions, its compatibility with specific
equipment must be decided by the person who designs the equipment or decides its specifications based on
necessary analysis and test results. The expected performance and safety assurance of the equipment will
be the responsibility of the person who has determined its compatibility with the product. This person should
also continuously review all specifications of the product referring to its latest catalog information, with a view
to giving due consideration to any possibility of equipment failure when configuring the equipment.
2. Only personnel with appropriate training should operate machinery and equipment.
The product specified here may become unsafe if handled incorrectly. The assembly, operation and
maintenance of machines or equipment including our products must be performed by an operator who is
appropriately trained and experienced.
3. Do not service or attempt to remove product and machinery/equipment until safety is confirmed.
1. The inspection and maintenance of machinery/equipment should only be performed after measures to
prevent falling or runaway of the driven objects have been confirmed.
2. When the product is to be removed, confirm that the safety measures as mentioned above are
implemented and the power from any appropriate source is cut, and read and understand the specific
product precautions of all relevant products carefully.
3. Before machinery/equipment is restarted, take measures to prevent unexpected operation and malfunction.
4. Our products cannot be used beyond their specifications. Our products are not developed,
designed, and manufactured to be used under the following conditions or environments. Use
under such conditions or environments is not covered.
1. Conditions and environments outside of the given specifications, or use outdoors or in a place exposed to
direct sunlight.
2. Use for nuclear power, railways, aviation, space equipment, ships, vehicles, military application, equipment
affecting human life, body, and property, fuel equipment, entertainment equipment, emergency shut-off
circuits, press clutches, brake circuits, safety equipment, etc., and use for applications that do not conform
to standard specifications such as catalogs and operation manuals.

Safety Instructions
Caution
We develop, design, and manufacture our products to be used for automatic control equipment, and
provide them for peaceful use in manufacturing business.
Use in non-manufacturing business is not covered.
Products we manufacture and sell cannot be used for the purpose of transactions or certification specified in the

Handling precautions
△
！ Caution
If power to this product is cut off due to a power failure,
etc. when it is in a controlled state, residual pressure will
be retained temporarily.
Handle carefully when operating with output pressure
released to the atmosphere, as air will continue to flow
out.
If supply pressure to this product is interrupted shut off,
while the power is still on, the internal solenoid valve will
continue to operate and a humming noise may be
generated.
Since the life of the product may be shortened, shut off
the power supply also when supply pressure is
interrupted shut off.
The optional cable connector is a 4 wire type.
When the monitor output (analogue output or switch
output) is not being used, prevent it from touching the
other wires as a malfunction could occur.
This product is adjusted for each specification at the
time of shipment from the factory. Avoid careless
disassembly or removal of parts, as this can lead to
malfunction.
Take the following steps to avoid malfunction due to
noise.
1. Install a line filter etc. to the AC power line to reduce
/ eliminate power supply noise.
2. Avoid malfunction due to noise by installing this
product and its wiring away from strong electric fields,
such as those of motors and power line, etc.
3. Be sure to implement protective measures against
load surge for induction loads (solenoid valves, relays
etc.).
4. Turn off the power supply before installing or removing
the connector.
Please note that the right angled cable connector does
not rotate and is limited to only one entry direction.

Wiring method [Power supply and input signal]

! Caution
1. Proceed carefully, as incorrect wiring can cause damage.
2. Use DC power supply with sufficient capacity and a low ripple (1% or less).
3. Turn off the power supply to remove and insert the connector.
4. Never turn the right angled type connector as it is not designed to turn.
Note) The wire color is for when
optional cable is used.

Setting method

! Caution
(1) If the incorrect key is pressed or incorrect information is displayed during setting, power
must be shut off and the procedure started again.
(2) It is recommended that the settings are changed without supply pressure.
The product operates immediately maximum and minimum pressures are set and the S-
key is pressed.
(3) Even if no input signal is input, when air is supplied to the inlet, the pressure set to "Min.
pressure" will be output to the secondary side, so be careful.
(4) Output pressure from this product and state of operation are changed by changing of
each setting and function.
Each setting and function should be operated by trained and experienced operator.

Gain setting
The response time can be changed by tuning the gain.
If the over-shoot is large, decreasing the gain tends to improve it, but the responsiveness
becomes slower.
Conversely, when the gain is increased, the response time tends to be faster, but stability will
be lost, which may cause hunting (unstable pressure).
In normal use, use the product in the condition when shipped, it is not always necessary to
adjust the gain.

Sensitivity setting
Adjusting the sensitivity changes the pressure correction operation near the set pressure point.
When the load capacity on the secondary side is large and hunting (unstable pressure) occurs,
decreasing the sensitivity tends to improve the hunting. However, as the pressure correction is
reduced, moderate pressure instability may occur.
