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 industries. Use in non-manufacturing industries 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. ■Do not touch the piping or its connected parts when the fluid is at high temperature. It may lead to burnt.
Page 7 ●Product handling ∗Installation •Tighten to the specified tightening torque. If the tightening torque is exceeded the mounting screws, brackets and the product can be broken. Insufficient torque can cause displacement of the product from its proper position and the looseness of the mounting screws. (Refer to "Mounting and Installation"...
Page 8 ∗Wiring •Do not pull the lead wires. In particular, never lift a product equipped with fitting and piping by holding the lead wires. Otherwise damage to the internal parts can result, causing malfunction or disconnection from the connector. •Avoid repeatedly bending, stretching or applying a heavy object or force to the lead wire. Repetitive bending or tensile stress can cause the sheath of the wire to peel off, or break the wire.
Page 9 ∗Environment •Do not use the product in an environment that is constantly exposed to the splash of water. Otherwise failure or malfunction can result. Take measures such as using a cover. •Do not use the product in an environment where corrosive gases or fluids could be splashed. Otherwise damage to the product and malfunction can result.
Page 10 ∗Adjustment and Operation •Connect a load before turning the power supply on. •Do not short-circuit the load. Although error is displayed when the product load has a short circuit, generated over current lead to cause the damage of the product. •Do not press the setting buttons with a sharp pointed object.
Page 11 ∗Handling of flow adjustment valve •When flow is adjusted with the flow adjustment valve, do not apply excessive force to rotate it. This can damage the valve mechanism. •When fixing the valve of the flow adjustment valve, do not apply excessive force to rotate the fixing knurl.

Page 18: Mounting And Installation
Mounting and Installation Installation •Use the product within the specified operating pressure and temperature range. •Proof pressure could vary according to the fluid temperature. Check the characteristics data for operating pressure and proof pressure. Mounting •Never mount the product in a location where it will be used as a support. •Mount the product so that the fluid flows in the direction indicated by the arrow on the side of the body.
Page 19: Installation
■Installation Bracket mounting (PF3W704/720/740) Mount the product (with bracket) using the mounting screws supplied (M4 x 4 pcs.). For models with flow adjustment valve attached, fix using 8 mounting screws. Bracket thickness is approx. 1.5 mm. Refer to the outline dimension drawing (page 86) for mounting hole sizes.
Page 20 Direct mounting (PF3W704/720/740) Mount using the self tapping screws (nominal size: 3.0 x 4 pcs.) for installation. For models with flow adjustment valve attached, mount using 8 self tapping screws. The tightening torque must be 0.5 to 0.7 N•m. Refer to the outline dimension drawing (page 86) for mounting hole dimensions.
Page 21: Piping
■Piping When connecting piping to the product, a spanner should be used on the metal piping attachment only. Using a spanner on other parts may damage the product. In particular, do not let the spanner come into contact with the M8 connector. The connector can be easily damaged.
Page 22 Caution The product body is made of resin. The installation and piping of the product must satisfy the following requirements. This may cause damage, breakage and/or water leakage of the product. •No load should be directly applied to the product. •Do not install piping to the product with a misalignment.
Page 23 How to adjust the flow rate (when a flow adjustment valve is mounted) (1) Rotate the knob of the valve to adjust the flow rate to the target value. (2) Be sure to confirm that there is no fluid leakage generated after adjustment. (When fluid leakage is generated, open and close the valve several times for re-adjustment, and confirm that there is no fluid leakage.) (3) Tighten the lock ring to fix the valve as necessary.
Page 24: Wiring
■Wiring Wiring of connector Connections should only be made with the power supply turned off. Use separate routes for the flow switch wiring and any power or high voltage wiring. Otherwise, malfunction may result due to noise. Ensure that the FG terminal is connected to ground when using a commercially available switch-mode power supply.

Page 27: Flow Setting
Flow Setting Measurement mode The mode in which the flow is detected and displayed, and the switch function is operating. This is the basic operating mode; other modes should be selected for set-point and other function setting changes. ∗: The outputs will continue to operate during setting. ∗: If a button operation is not performed for 30 seconds during the setting, the display will flash (This is to prevent the setting from remaining incomplete if, for instance, an operator were to leave during setting).
Page 28 Default settings When the flow exceeds the set value, the switch will be turned ON. When the flow falls below the set value by the amount of hysteresis or more, the switch will be turned OFF. If the operation shown the below is acceptable, please keep this setting. Refer to the following pages for how to change the settings.
