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)*1), and other safety regulations . - Page 4 Safety Instructions Caution 1.The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary. If anything is unclear, contact your nearest sales branch.
- 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. ■After maintenance is complete, perform appropriate functional inspections and leak tests. Stop operation if the equipment does not function properly or there is a leakage of fluid. When leakage occurs from parts other than the piping, the product might be faulty.

- 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 of the connector. Avoid repeatedly bending or stretching the lead wire, or placing heavy loads on it. Repeated bending stress or tensile stress can cause damage to the sheath, or breakage of the wires.
- 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 load before turning on the power. Supply the power when there is no flow. If using the product to detect very small flow rates, warm up the product for 10 to 15 minutes first. There will be a drift on the analogue output of approximate 2 to 3% immediately after the power supply is turn on, within 10 minutes.

Page 17: Wiring
■Wiring Connections should only be made with the power supply turned off. Use separate routes for the product 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 18 Attaching the sensor connector to the lead wire (When the product connects to the PF2A2 Refer to the PF2A2 operation manual for details of the sensor connector pin numbers. Strip the lead wire as shown. Do not cut the insulator. Insert the corresponding wire colour into the pin number printed on the sensor connector, to the bottom, then part A shown should be pressed in by hand to make temporary connection.
