Two Hand Control Valve This may cause the output to malfunction even when operated at the same time.
There may be the case it will vary substantially depending on an ambient environment.

They may vary significantly with the surrounding environment.
If the tightening torque is exceeded the mounting screws and brackets may damaged. If the tightening torque is insufficient, the product may be displaced and the mounting screws may come loose (Refer to page 13 "Mounting and Installation".)
Therefore, it should be noted that the described characteristic values may vary depending on the loop conditions. Main circuit switch 5: (ANR) shows standard air in accordance with JIS B0120. 6: The visibility of LCD display may be reduced at lower OUT(-) temperature.
Command pulses may be input in any of three different forms, for which positive or negative logic can be chosen. Arrow or in the table indicates the timing of importing a pulse train. Aand B-phase pulse trains are imported after being multiplied by 4. Parameter No.
Improper voltage may cause malfunction or coil damage. Warnings or specifications printed on or affixed to the product should not be erased, removed, or covered up. Please consult with SMC before applying paint to resinous parts, as this may have an adverse effect due to the solvent in the paint. 3. Check the connections.
In such cases, human injury may occur; e.g., by catching hands or feet in the machinery, or damage to the machinery itself may occur. Therefore, the machine should be designed to avoid such dangers. (4) A protective cover is recommended to minimize the risk of personal injury. If a stationary object and moving parts of a cylinder are in close proximity, personal injury may occur.
Double-acting cylinders may be ordered with a common rod that protrudes from both cylinder end caps. A nut may be placed on one rod end to retain spacers that will limit the stroke distance. Be sure to guard the spacer end because pinch points will be present. DM1, DM2 and HD1 Cylinders are double acting.

If the facility water in a cooling tower is used, the water quality standard will be satisfied at the initial stage, however, if it is used in an air contaminated environment, sulfurous acid gas in the air may dissolve into the facility water, forming sulfuric acid which may corrode the electro-thermal surface.

With non-polar type valves, at times of sudden interruption of the loading power supply, such as emergency shutdown, surge voltage intrusion may be generated from loading equipment with a large capacity (power consumption), and a valve in a de-energized state may switch over (see Figure 1).
This may cause switch output malfunction. 9. Malfunctions stemming from noise may occur if the wire is installed in the same route as that of power or high-voltage cable. Wire the pressure switch independently. 10. Confirm proper insulation of wiring.
The product may not operate correctly if the pilot valve orifice diameter is inadequate. (port size: 3/4, 1) Depending on the pilot piping port size1 or length, the valve may not operate correctly. 1 The I.D. of the pilot piping must be larger than the pilot valve orifice diameter to use. The maximum pilot piping I.D. is 10 mm.
If the operation is restarted within five minutes, the protection circuit may activate and the operation may not start properly.
It may not be possible to connect them, or they may cause other trouble, such as air leakage or the tubing coming out after connection.
Insufficient tightening torque may result in loosening or sealing failure. Excessive tightening torque may damage the thread, etc.
