Contact SMC beforehand and take special consideration of safety measures if the product is to be used in any of the following conditions.
1. Conditions and environments outside of the given specifications, or use outdoors or in a place exposed to direct sunlight.
2. Installation on equipment in conjunction with atomic energy, railways, air navigation, space, shipping, vehicles, military, medical treatment, combustion and recreation, or equipment in contact with food and beverages, emergency stop circuits, clutch and brake circuits in press applications, safety equipment or other applications unsuitable for the standard specifications described in the product catalog.
3. An application which could have negative effects on people, property, or animals requiring special safety analysis.
4. Use in an interlock circuit, which requires the provision of double interlock for possible failure by using a mechanical protective function, and periodical checks to confirm proper operation.
Caution
- The product is provided for use in manufacturing industries.
The product herein described is basically provided for peaceful use in manufacturing industries.
If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary.
If anything is unclear, contact your nearest sales branch.
Limited warranty and Disclaimer/Compliance Requirements
The product used is subject to the following “Limited warranty and Disclaimer”
and “Compliance Requirements”.
Read and accept them before using the product.
Limited warranty and Disclaimer
-
The warranty period of the product is 1 year in service or 1.5 years after the product is delivered,whichever is first.2)
Also, the product may have specified durability, running distance or replacement parts.
Please consult your nearest sales branch. -
For any failure or damage reported within the warranty period which is clearly our responsibility, a replacement product or necessary parts will be provided.
This limited warranty applies only to our product independently, and not to any other damage incurred due to the failure of the product. -
Prior to using SMC products, please read and understand the warranty terms and disclaimers noted in the specified catalog for the particular products.
- Vacuum pads are excluded from this 1 year warranty.
A vacuum pad is a consumable part, so it is warranted for a year after it is delivered.
Also, even within the warranty period, the wear of a product due to the use of the vacuum pad or failure due to the deterioration of rubber material are not covered by the limited warranty.
Compliance Requirements
- The use of SMC products with production equipment for the manufacture of weapons of mass destruction (WMD) or any other weapon is strictly prohibited.
- The exports of SMC products or technology from one country to another are governed by the relevant security laws and regulation of the countries involved in the transaction. Prior to the shipment of a SMC product to another country, assure that all local rules governing that export are known and followed.
Caution
SMC products are not intended for use as instruments for legal metrology.
Products that SMC manufactures or sells are not measurement instruments that
are qualified by pattern approval tests relating to the measurement laws of
each country.
Therefore, SMC products cannot be used for business or certification ordained
by the measurement laws of each country.
Operator
- This operation manual is intended for those who have knowledge of machinery using pneumatic equipment, and have sufficient knowledge of assembly, operation and maintenance of such equipment. Only those persons are allowed to perform assembly, operation and maintenance.
- Read and understand this operation manual carefully before assembling, operating or providing maintenance to the product.
Safety Instructions
Warning
-
Do not disassemble, modify (including changing the printed circuit board) or repair.
An injury or failure can result. -
Do not operate the product outside of the specifications.
Do not use for flammable or harmful fluids.
Fire, malfunction, or damage to the product can result.
Verify the specifications before use. -
Do not operate in an atmosphere containing flammable or explosive gases.
Fire or an explosion can result.
This product is not designed to be explosion proof. -
Do not use the product in a place where static electricity is a problem.
Otherwise it can cause failure or malfunction of the system. -
If using the product in an interlocking circuit:
Provide a double interlocking system, for example a mechanical system
Check the product regularly for proper operation
Otherwise malfunction can result, causing an accident. -
The following instructions must be followed during maintenance:
Turn off the power supply
Stop the air supply, exhaust the residual pressure and verify that the air is released before performing
maintenance
Otherwise an injury can result.
Caution
-
After maintenance is complete, perform appropriate functional inspections and leak tests.
Stop operation if the equipment does not function properly or there is a leakage of fluid.
When leakage occurs from parts other than the piping, the product might be faulty.
Disconnect the power supply and stop the fluid supply.
Do not apply fluid under leaking conditions.
Safety cannot be assured in the case of unexpected malfunction. -
Use within the specified operating pressure.
Otherwise it can cause damage to the Pressure Sensor or inability to measure correctly.
If fluid is supplied at a pressure exceeding the proof pressure, the ceramic diaphragm will be damaged. A significantly damaged diaphragm will result in external leakage. In addition, the power supply is short circuited depending on the applied fluid. Please use a power supply which includes short circuit protection.
NOTE
-
Follow the instructions given below when designing, selecting and handling the product.
-
The instructions on design and selection (installation, wiring, environment, adjustment, operation, maintenance, etc.) described below must also be followed.
Product specifications
Use the specified voltage.
Otherwise failure or malfunction can result.
Applicable fluid is a fluid that does not corrode C3604 + electroless nickel plated, AI203 (aluminum oxide) and FKM. -
Do not use a fluid containing chemicals, synthetic oils including organic solvent, salt and corrosive gases.
Otherwise, damage to the product and malfunction can result.
Check the details of the specifications before using.
Reserve a space for maintenance. -
Allow sufficient space for maintenance when designing the system.
A ceramic diaphragm type pressure sensor is used in this product. The ceramic diaphragm can be damaged by overpressure from hydraulic shock, which can be generated when condensate in the fluid collides with the sensor during pressure fluctuation. This is also known as “water hammer”.
To mitigate hydraulic shock, it is recommended to insert an orifice between the fluid and the sensor. A gas pocket also needs to be between the orifice and the sensor to cushion the shock pulse. The sensor would then need to be located above the orifice with the orifice mounted vertically so that no fluid gets between the orifice and sensor. -
Some recommended and NOT recommended examples are shown in the following figure. Part numbersZS-31-X175 or X188 are applicable orifices (called throttles in product literature).
Names of Parts of Product and Handling Precautions
Only fluids which are non-corrosive to C3604 + electroless nickel plated, AI203 (aluminum oxide) and FKM should be used.
