SMC CORPORATION OF JAPAN This value can be set to a one time offset value. DirectSet Enter a value using the + and keys. Analog In An Analog input value from a System Input (A01, A02, A03, ... A08) FB Value An analog value contained in a Function Block (T, t, N, n, Direct set, etc.)
The Card Motor uses an optical sensor to detect the position, so if it is exposed to a strong light source such as direct sunlight, a malfunction could result. In such a case, install a light shielding plate such as a cover to shield the sensor from light. 4. Do not use the products in an environment where flammable, explosive or corrosive gases, liquids or other substances are present.
The VQ7-□-FPG perfect valve is a valve in which a perfect spacer (VV71-FPG/VV72-FPG) with a pilot check valve function is inserted between the exhaust center and the base. Although it can hold the cylinder at an intermediate position for longer than the type with a closed center (metal seal), with the perfect valve, it cannot be guaranteed that the position will not deviate.
Do not install the product in an environment under the effect of vibrations and impacts. It will cause failure or malfunction. 17. When a surge-generating load, such as a relay or solenoid valve, is driven directly, use a product that incorporates a surge absorption element. -21- 18.
Caution Caution indicates a hazard with a low level of risk which, if not avoided, could result in minor or moderate injury. Warning Warning indicates a hazard with a medium level of risk which, if not avoided, could result in death or serious injury. Danger Danger indicates a hazard with a high level of risk which, if not avoided, will result in death or serious injury. Warning 1.
reference value for correcting an error in reciprocal operation. *5 Impact resistance: No malfunction occurred when the actuator was tested with a drop tester in both an axial direction and a perpendicuar direction to the lead screw.
Ion Balance Sensor IZF21 and IZF31 have a built-in sensor to maintain the offset voltage (ion balance) performance in an appropriate condition.
The wire connected to an output pin which is On (Signal or Function Block) will change to a red color.
Actuator drive When an actuator, such as a cylinder, is to be driven Provide ventilation when using a valve in a confined area, such as in a closed control panel.
If many iron particles, such as cutting chips or spatters accumulate around a cylinder with the auto switches or an actuator or if a magnetic substance (attracted by a magnet) is put close to a cylinder with the auto switch or an actuator, the magnetic force inside the cylinder or actuator loses, causing the auto switch to malfunction. 6.
(The switch will stay ON all the time.) 1) For an auto switch without a contact protection circuit, use a contact protection box when the wire length is 5m or longer. 2) Even if an auto switch has a built-in contact protection circuit, when the wiring is more than 30m long, it is not able to adequately absorb the rush current and its life may be reduced.
Cautions for use in an interlock circuit When an auto switch is used for an interlock signal requiring high reliability, devise a double interlock system to avoid trouble by providing a mechanical protection function, or by also using another switch (sensor) together with the auto switch. Also perform periodic maintenance and confirm proper operation. 9.
Fig.1 Equivalent circuit of a NPN type switch with the output off Fig.2 shows an equivalent circuit of a NPN switch with the output on. In this circuit the load is powered. When using a PLC, the input section sees a low level. Another type of a switch output is a PNP switch. Refer to Difference between NPN and PNP Output on the next page.
Therefore, a method of connection which can absorb the displacement (i.e. floating mechanism) should be considered. A cylinder (Basic series MY3A/MY3B) that is suitable to be used as a driving source and a floating joint as an option are available. Please refer to the catalog for details.
Install an air filter. Install an air filter upstream near the valve. Select an air filter with a filtration size of 5 m or smaller. 3. 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 the malfunction of pneumatic equipment, such as valves.

For installation and removal, use an appropriate pair of pliers (tool for installing a type C snap ring). 2. Even if a proper plier (tool for installing type C snap ring) is used, it is likely to inflict damage to a human body or peripheral equipment, as a snap ring may be flown out of the tip of a plier (tool for installing a type C snap ring).
