Solid State Auto Switch When an amount of steel chips or steel dusts such as sputters of welding accumulate around an actuator equipped with Auto switch, or magnetic bodies (those attracted by magnet) are gathered closely to the actuator, they can weaken a magnet inside the actuator causing inoperativeness of the Auto switch. Do not use the product in an environment where heat cycle exists.
Install an air filter at the upstream side of valve. Select an air filter with a filtration degree of 5m or finer. 18 - 3. Install an aftercooler, air dryer or drain catch before the filter and take appropriate measures. Compressed air that contains excessive foreign material may cause malfunction of valves and other pneumatic equipment.
if an operator does not follow the specified procedures during the operation or maintenance of the product or does not follow the instructions necessary to avoid it.
Caution (1) Install an air filter. (4) When connecting the tubing, take pressure or possible changes to the tubing length into account, and allow a sufficient margin. Install an air filter at the upstream side of valve. Select an air filter with a filtration degree of 5m or finer. Failure to do so may result in fitting breakage or detachment of the tubing.
Install an air filter. Caution Install an air filter upstream near the valve. Select an air filter with a filtration size of 5 or smaller. 2. Take measures to ensure air quality, such as by installing an aftercooler, air dryer, or water separator. Compressed air that contains a large amount of drainage can cause malfunction of pneumatic equipment such as valves.
Low temperature operation 1) The valve can be used in an ambient temperature of not less than 5C.
Do not use the product in an environment where corrosive gases or fluids could be splashed. Otherwise damage to the product and malfunction can result. Do not use in an area where surges are generated.
Caution (1) Install an air filter. Install an air filter at the upstream side of valve. Select an air filter with a filtration degree of 5m or finer. (2) Install an aftercooler, air dryer or water separator, etc. Compressed air containing a large amount of drainage can cause the malfunction of pneumatic equipment.
Assembly,handling,repair and element replacement of pneumatic systems should be performed by a knowledgeable and experienced person. (1)Install an air filter. Install an air filter upstream near the valve.
Low temperature operation 1) The valve can be used in an ambient temperature of not less than 5C.
If the product is an external type pilot, it is not splash proof. Be careful not to expose it to any fluid when maintaining the valve. When replacing a valve, if an external pilot solenoid valve is mounted in the wrong direction, it may malfunction or leak air.
(control operation) LC3F2 Command an operation in the reverse direction only after a cylinder rod stopped completely. LC3F2 Do not operate a cylinder rod with an external force when the electric cylinder directional control driver is turned off or output is in the off state.
Resistance of equipment in the Use components and equipment of an appropriate size. It affects the piping diameter and length. Equipment at the exhaust side should also be of an appropriate size. Refer to the catalog and operation manual of the components and equipment for details. piping route is too large 3.
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.
If any of the examples below are applicable, there may be an internal problem with the valve.
It is recommended to use an automatic drain system for savings in labor. When using an SMC automatic drain system, Model AD402-03D-6-A (Model AD402-04D-6-A for the Model HAA37 units), a base as shown in the following sketch, is required.
If the compressed air supply includes chemicals, synthetic materials (including organic solvents), salinity, corrosive gas, etc., it can lead to damage or malfunction. 2) Install an air filter. Install an air filter at the up stream side to the valve. Filtration degree should be 5 m or less. 3) Install an air dryer, after cooler, etc.
Select a fitting with an I.D. greater than 8 for the VP344 and the VP342; more than 10 for the VP544 and VP542, and more than 12 for VP744 and VP742 when piping length is less than 3 meters. Use an external pilot when there is a small flow outlet of the valve.
