- Page 2 Ｆｏｒ Ｓａｆｅｔｙ Ｕｓｅ To use this product safety, basic knowledge of pneumatic equipment, including materials, piping, electrical system and mechanism, is required (ISO 4414 *1 JIS B 8370 *2). We do not bear any responsibility for accidents caused by any person without such knowledge or arising from im- proper operation.
- Page 3 CAUTION Points to caution when handling the product (1) Inferior quality air will deteriorate the product characteristics and affect its durability badly. Use an air dryer, filter and Oil mist filter to eliminate solid material, moisture and tar and thus provide clean air from the pressure source.
- Page 4 (８) Avoid operating the product in places where it may be affected by direct sunlight, water or oil. (９) If the product remains connected to its supply pressure for a long time while leaving the power turned off, the output pressure may increase to the level of the supply pressure.

Page 6: Design And Selection
１ DESIGN AND SELECTION 1. DESIGN AND SELECTION (1) With a thorough understanding of compressed air ! WARNING : characteristics, design a pneumatic circuit. Where instantaneous stop holding at emergency stop is required, the same function as in the mechanical or hy- draulic or electrical units cannot be expected. There arise pop-up, jet-out and leaking phenomena caused by compressibility and expansibility, which are air characteristics. (2) Prior to use, always ensure that the product with- stands the operating environment. - Page 7 １ DESIGN AND SELECTION (1) Note the maintenance conditions clearly in the ! CAUTION : equipment instruction manual. The product functions may significantly lower, depending on the operating condition, operating environment and maintenance situation, thereby safety might not be se- cured. If this maintenance work is conducted accurately and correctly, it is possible to exhibit the product func- tion and performance sufficiently. (2) Use be a constant voltage power supply. (3) Check the leak current to avoid a malfunction caused ...

(2) Do not wash and coat the MEVT, using water and solvent . Some plastics parts may be damaged. The coating agent may block the exhaust port, causing malfunctions. -
Page 10: When Installing
２ INSTALLATION When installing: ! CAUTION : (1) Keep a sufficient space for removal & re-installation, wiring and piping work around the EVT. (2) Provide a pneumatic filter just in the pre-stage of the circuit in which the pneumatic equipment is used. (3) The response time is af- fected by operating pressure and load ca- pacity. When stable reproduci- bility is required for this responsibility, set up a Air filter ... - Page 11 ２ INSTALLATION When piping work ! CAUTION : (1) Do not detach the MEVT packing bag until piping work is started. If the packing bag is removed before piping work, foreign substance may intrude into the interior EVT from the piping port, thus causing trouble and malfunctions, etc. (2) In piping work, flushing is required just before connecting to the pneumatic equipment. Foreign substance intruding inside during piping work must not incorporate into the ...

Soft nylon (F-1500 Series) Polyurethane (U-9500 Series) When a commercially available tube is used, give care to outside diameter accuracy, wall thickness and hardness. The hardness of the polyurethane tube used should be 93 deg. min. (Rubber hardness tester) If a tube that does not satisfy outside diameter accuracy and hardness as specified is used, the chucking force may lower, thereby causing the tube to come off and ...

Page 13: Operation
３ OPERATION 3. OPERATION Operating Conditions: The pressure supplied to the electro-pneumatic regulator should be used in the pressure range from the minimum operating pressure to maximum oper- ating pressure that is specified in “5.1 Specifications”. For supply power, use a stabilized power supply with the ripple rate 1% max. at supply voltage 24 V DC+/-10%. - Page 14 ３ OPERATION The pneumatic equipment should be disassembled and ! CAUTION : re-assembled by the worker who got technical knowledge thereon: this work requires the level of pneumatic skill qualification class 2 or higher. When the pneumatic equipment is disassembled and re- assembled, read the instruction manual for the corre- sponding ...

- Page 21 ６ WIRING 6. WIRING How to wiring of electric equipment, supply and exhaust block . There are three types of electric equipment, supply and exhaust block; Common terminal stand type (T11R), D-sub connector type (T30R). Cautions common to all models Check the operating voltage.
- Page 22 ６ WIRING In the wiring of the common terminal stand type and D-Sub connector type, the power grounding line and the signal common line are used commonly. There- fore, when multiple EVT-series products are driven by one PLC and D/A unit, the correct signals may not be output due to wiring depending on the circuit method of the D/A unit.
