Depending on the external switch output type, wire the switch to the communication connector for contact input / output (which is included as an accessory) as shown below. Mount the ferrite core (3 turns), which is included as an accessory. This is an example of wiringRefer to the Communications Operation Manual for more details.

Combination Symbol: K2 Combination Symbol: K7 An N.C. solenoid valve is used as the supply valve. Also, an external 2 port valve (vacuum valve) must be provided to serve as the vacuum release valve. An air operated N.O. valve is used as the supply valve. An N.C. solenoid valve is used for the vacuum release valve.
As a result, the inside of the bowl q is shut off from the outside air. Therefore, even if there is an accumulation of condensate in the bowl q, it will not drain out.
Note 2) 4 to 20 mA DC is not possible with the 2-wire type. Power supply voltage (24 VDC or 12 to 15 VDC) is required. Note 3) Value for the state with no over current circuit included. If an allowance is provided for an over current circuit, the input impedance varies depending on the input power supply. This is 350 or less for an input current of 20 mA DC.
This system should not be applied with an undue force such as caused by piping installation.
This product cannot be used as a check regulator by installing it between solenoid valve and actuator. 3. Port with a pressure gauge or a plug can be used as an OUT port.
Use caution, as operating above the prescribed values may lead to dropping of the load. The cushion effect (smooth start-up, soft stop) exists only before the stroke end in the stroke ranges indicated in the table below. The cushion effect (smooth start-up, soft stop) cannot be obtained in an intermediate stop or return from an intermediate stop using an external stopper, etc.
Manual Override Caution Light/Surge Voltage Suppressor Caution Without an electric signal for the solenoid valve the manual override is used for switching the main valve. Push type is standard. Locking type (Tool required) is available as an option. 1.
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 moisture can cause malfunction of pneumatic equipment such as rotary tables. Therefore, take appropriate measures to ensure air quality, such as by providing an aftercooler, air dryer, or water separator. 4.
