VNA Series Extended periods of continuous energization If a valve is continuously energized for long periods, heat generation of the coil may result in reduced performance and shorter service life. This may also have an adverse effect on the peripheral equipment in proximity.
If the SI unit is not assembled properly, inside PCBs may be damaged or liquid and/or dust may enter into the unit.
The element guide may not necessarily be taken out. It is not a must to take out the element guide. After removal of the element mounting bracket, the elements and joints can be taken out as a unit by taking out the element guide in accordance with instructions shown in Fig. 1. Note) Joint may not be necessary.
If the effective area is smaller, it may encounter an unexpected sudden slide table movement. Install a solenoid valve for braking as close to the cylinder as possible. If there is a long distance between the cylinder and valve, it may cause fluctuations in the stop accuracy or unexpected sudden slide table movements.
If workpieces collide in the locked condition, the lock may disengage due to the shock, or the lock mechanism and piston rod may be damaged, causing a dramatic decrease of the product life and/ or further damage. 2. Model MLGPL (Ball bushing bearing) cannot be used as a stopper.

Note: Over-tightening of fittings may cause fracturing of the thread sections or deformation of the gaskets, leading to air leaks. If the fittings are under-tightened, the loosening of thread and air leaks may occur. Refer to the Best Pneumatics vol.4 catalog for details on compressed air quality. Operating Environment Lubrication Caution Warning 1. Lubrication 1.

If screwed in too far, this may cause air leakage due to breaking of threads or distortion of the gasket, etc. If not screwed in far enough, this may cause a loose fitting or air leakage, etc.

Switch output may malfunction. 3. Wire separately from power lines and high voltage lines, avoiding wiring in the same conduit with these lines. Malfunctions may occur due to noise from these other lines. 4. If a commercial switching regulator is used, make sure that the F.G. terminal is grounded.
The period may vary depending on the temperature and other conditions. In some cases the absorber may need to be replaced before the allowable operating cycle above. 1. Use caution not to be exposed to cutting oil, water, or dust, etc.
The grease used on internal sliding parts and seals may come in contact with outlet side components. Please consult with SMC if this is not desirable. 4. Do not disassemble the product or make any modifications, including additional machining. It may cause human injury and/or an accident. 1.
Doing so may cause human injury and/or an accident. (4)The flow rate characteristics for each product are representative values. The flow rate characteristics are characteristics of each individual product. Actual values may differ depending on the piping, circuitry, pressure conditions, etc.

Therefore, if an air compressor has a small air delivery, the pressure may not be sufficient. Auto Drain Caution M Refrigerant with GWP Reference Global Warming Potential (GWP) Refrigerant The auto drain may not function properly, depending on the quality of the compressed air. Check the operation once a day.
When the handle is rotated with a tool, it may apply excessive torque to the handle or inside the valve body and it may cause damage. Rotate the handle by hand. 9. When locking the valve with LOTO feature in the closed position, use safety lockout hasp. (AP3657, AP4657, AP3157, AP3900) The valve with LOTO feature has a built in LOTO capability.
Rotating the knob excessively may damage internal parts. 2. Rotate the pressure adjustment knob only after unlocking. If rotated while locked, the connecting part between the body and the bonnet may be damaged. 3. For pressure adjustment knob operation, a hexagon wrench can be used in the direction of the pressure increase.
Air leakage may be happened, depending on the position in which a rod seal is fitted.
