Achieves high specs as a key valve for mid-sized actuators. SOLENOID VALVES The powerful and low current 280 series solenoid valves inherited the features of thin and square body concept. It demonstrates the potential for enabling to fast operation of middle-sized 50125 cylinders. Moreover, use of a low current solenoid ensures reliability. In addition, optional items offer assembly and maintenance effectiveness, with a 5- port and 2-, 3-position line-up products achieving easy to use. NEW DYNA cylinders SERIES Low Power Consumption and Highly Reliable Solenoids A built-in varistor for AC and flywheel diode for DC are standard equipment for surge suppression, as a feature of Koganei s highly reliable valve series designs. Achieves low current requirements of DC24V-65mA (1.6W), with advanced levels of reliability and easy to use. Optional System Emphasizes Function Two types of plug connectors, straight and L types, achieve easy wiring installation and Rodless cylinders removal. In addition, an Rc1/4 connection port size eases piping connections with actuators, to offer large piping space saving with the F type and A type manifolds, and to increase space efficiency. 664

Handling Instructions and Precautions 680 Solenoid Internal circuit DC12V, DC24V Standard solenoid (surge suppression) Lead wire DC12V: Brown DC24V: Red Lead wire: Black Solenoid with (surge suppression) Order code-psl, -PLL Lead wire DC12V: Brown DC24V: Red Lead wire: Black Solenoid with DIN connector (surge suppression) Order code-39 GND. AC0V, AC200V Standard solenoid (surge suppression) Lead wire AC0V: Yellow AC200V: White Varistor Solenoid with (surge suppression) Order code-psl, -PLL Lead wire AC0V: Yellow AC200V: White Solenoid with DIN connector (surge suppression) Order code-39 GND. Short circuit protection diode Flywheel diode Diode Solenoid : Red Solenoid Light emitting diode Light emitting diode Color of AC0V: Yellow AC200V: Green Frame Cautions: 1. Do not apply megger between the lead wires. 2. While there is no danger with a DC solenoid of a short circuit due to the wrong polarity, the valve will not operate. 3. Leakage current inside the circuit could result in failure of the solenoid valve to return or in other erratic operation. Always use within the range of the allowable leakage current. If circuit conditions, etc., cause the leakage current to exceed the maximum allowable leakage current, consult us. 4. For double energizing, avoid energizing both solenoids simultaneously. The valve could fall into a neutral state. Plug connector Attaching and removing plug connector Use fingers to insert the connector into the pin, push in until the lever claw catches on the convex section on the connector housing, and complete the connection. To remove the connector, squeeze the lever along with the connector, lift the lever claw up from the convex section on the connector housing, and pull out. Convex section Pin Connector housing DC Connector Contact Lever Illustration shows the 1 series. C Connector assembly Crimping of connecting lead wire and contact To crimp lead wires into contacts, strip off 4A of the insulation from the end of the lead wire, insert into the contact, and crimp it. Be sure at this time to avoid catching the insulation on the expose wire as crimping section. Contact Hook Insulation crimp tab Expose wire crimping section Expose wire 4mm Lead wire Equivalent to AWG2226 InsulationMaximum outer diameter1.7 Cautions: 1. Do not pull hard on the lead wire. 2. Always use the dedicated tool for crimping of connecting lead wire and contact. Contact: Model 702062-2M Manufactured by Sumiko Tech, Inc. Crimping tool: Model F1-702062 Manufactured by Sumiko Tech, Inc. Attaching and removing contact and connector Insert the contact with lead wire into a plug connector hole until the contact hook catches and is secured to the plug connector. Confirm that the lead wire cannot be easily pulled out. To remove, insert a tool with a fine tip (such as a small screwdriver) into the rectangular hole on the side of the plug connector to push up on the hook, and then pull out the lead wire. Cautions: 1. Do not pull hard on the lead wire.it could result in defective contacts, breaking wires, etc. 2. If the pin is bent, use a small screwdriver, etc., to gently straighten out the pin, and then complete the connection to the plug connector. Common terminal plug connector 1. Common terminal pre-wiring for DC plus side and AC. Order code With straight connector: -CPSL With L connector: -CPLL Polarity is for DC. COM. Crossover wire Connector Connector housing Color of COM, crossover wire DC12V Brown DC24V Red AC0VYellow AC200VWhite 2. Common terminal pre-wiring for DC minus side Order code With straight connector: -CMSL With L connector: -CMLL COM. Crossover wire Connector Connector housing Color of COM, crossover wire DC12VBlack DC24VBlack Cautions: 1. The diagram shows the straight connector configuration. While the connector s facing direction is different in the case of the L connector, in every case the COM. lead wire outlet comes from the last station s mounted valve. 2. Since the COM. terminal is connected to a crossover terminal inside the connector housing, the connector cannot be switched between a plus common and a minus common by changing the connectors.
Manual override Non-locking type To operate, press the manual override all the way down. In the single solenoid, the valve works the same as an energized state as long as the manual override is pushed down, and returns to the rest position upon release. In the double solenoid, pressing the manual override on the () side switches the state of the () to energized state, and the unit remains in the state even after the manual override is released. To return to the rest position, operate the manual override on the () side. PUSH Illustration shows the 1 series. Locking protruding type Use a small screwdriver to turn the adjusting knob several times in a clockwise direction, and lock the manual override in place. When locked, turning the adjusting knob several times in a counterclockwise direction releases a spring on the manual override, returns it to the original position, and releases the lock. For the locking protruding type, if the adjusting knob is never turned, this type acts just like the non-locking type, like the valve energizing status as long as the manual override is pushed down, and returning to the rest position upon release. PUSH Illustration shows the 040 series. Cautions: 1. The 280 series are internal pilot type solenoid valves. As a result, the manual override cannot switch the main valve without supplying air from the P port. 2. Always release the lock on the locking or locking protruding type manual override before commencing normal operation. DIN connector Wiring instructions Remove the cover mounting screws, and lift the terminal cover off from the solenoid. Insert a screwdriver, etc. (blade width of 4 4.5A), into the groove on the boundary between the terminal body and terminal cover, lightly pry up the terminal body and lift it from the terminal cover. Slip a cable ground, washer, and cable gasket over a cabtire cable (outer diameter 68A), insert the cable into the terminal cover's wiring outlet, and connect the core wire of the lead wire to the each terminal of a terminal block (screwdriver blade width of about 3A). 2 1 Solenoid terminal arrangement Screwdriver 44.5mm) Terminal body Outer diameter 68mm Cable ground Washer Cable gasket Terminal cover 3. Do not attempt to operate the manual override with a pin or other object having an extremely fine tip. It could damage the manual override button. 4. Do not turn the adjusting knob more than the amount needed. It could result in defective operation.
