Page 3: Safety Instructions
Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) , and other safety regulations. - Page 4 Safety Instructions Caution We develop, design, and manufacture our products to be used for automatic control equipment, and provide them for peaceful use in manufacturing business. Use in non-manufacturing business is not covered. Products we manufacture and sell cannot be used for the purpose of transactions or certification specified in the Measurement Act.
- Page 5 Operator This operation manual is intended for those who have knowledge of machinery using pneumatic equipment, and have sufficient knowledge of assembly, operation and maintenance of such equipment. Only those persons are allowed to perform assembly, operation and maintenance. Read and understand this operation manual carefully before assembling, operating or providing maintenance to the product.
- Page 6 Caution ■Do not touch the terminals and connectors while the power is on. Otherwise electric shock, malfunction or damage to the product can result. ■Perform sufficient trial run. Otherwise, injury or damage to the system can result due to suction failure depending on the conditions of the suction of the workpiece or the pressure switch settings.
- Page 7 ●Product handling Installation •Tighten to the specified tightening torque. If the tightening torque is exceeded the mounting screws and brackets may be broken. If the tightening torque is insufficient, the product can be displaced and loosen the mounting screws. (Refer to page 16) •Be sure to ground terminal FG when using a commercially available switch-mode power supply.
- Page 8 Wiring •Do not pull the lead wires. In particular, never lift a Pressure switch equipped with fitting and piping by holding the lead wires. Otherwise damage to the internal parts can result, causing malfunction or to be off the connector. •Avoid repeatedly bending or stretching the lead wire, or placing heavy load on them.
- Page 9 •Prevent foreign matter such as remnant of wires from entering the Pressure switch. Take proper measures for the remnant not to enter the Pressure switch in order to prevent failure or malfunction. •Do not use the product in an environment that is exposed to temperature cycle. Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.

Page 33: Example Of Ejector Operation
Example of Ejector Operation ■Example ○Energy saving operation (Supply valve: N.C.) (1) The vacuum instruction turns on (0 to 1). (2) The supply valve is automatically OFF (not-energized) when the vacuum pressure reaches P2. (3) When the vacuum pressure drops by P2-H2, the supply valve is automatically ON (energized) again. (4) Repeat steps (2) and (3) unless the valve protection function is activated. - Page 34 ○Energy saving operation (Supply valve: N.O.) (1) The vacuum instruction turns off (1 to 0). (2) The supply valve is automatically ON (energized) when the vacuum pressure reaches P2. (3) When the vacuum pressure drops by P2-H2, the supply valve is automatically OFF (not-energized) again. (4) Repeat steps (2) and (3) unless the valve protection function is activated.
- Page 35 ○Valve protection operation When the valve has switched ON/OFF a set number of times during operation of energy saving function, the energy saving will turn off, and continuous absorption will resume. Diagnostic information is then issued. *The graph is supply valve: N.C. type. *The energy saving control can not be used for ZB series.
- Page 36 ○Automatic release valve operation The release pressure can be used without instructing release instruction bit. (1) The vacuum instruction turns on (0 to 1). (2) The workpiece is moved to the release position, and then the vacuum instruction turns off (1 to 0). (3) After delay time, the release valve is ON.
