Page 3: Safety Instructions
Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions are categorized into three groups, "Caution", "Warning" and "Danger" depending on the level of hazard and damage, and the degree of emergency. They are all important notes for safety and must be followed in addition to International Standards (ISO/ IEC), Japan Industrial Standards (JIS) and other safety regulations... - Page 4 Safety Instructions Caution The product is provided for use in manufacturing industries. The product herein described is basically provided for use in manufacturing industries. If the product is being considered for use in other industries, consult SMC beforehand and exchange specifications or a contract if necessary.

- Page 6 Caution ■Do not touch the terminals and connectors while the power is on. Otherwise electric shock, malfunction or damage to the switch can result. Do not touch ■Do not touch the piping joint or piping when hot fluid is used. It may lead to burn.
- Page 7 ● Product handling Installation - Tighten to the specified tightening torque. If the tightening torque is exceeded, the mounting screws and brackets may be damaged. 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 16 to 21).) - Be sure to ground terminal FG when using a switch-mode power supply that is commercially obtained.
- Page 8 - Design and install the product so that fluid always fills the detection passage. 1, If the product is used when the detection passage is not filled, correct detection signal is not output from the electrodes, making correct measurement impossible. For vertical mounting, apply fluid from the bottom to the top.
- Page 9 * Wiring (Including connecting/disconnecting of the connectors) Do not pull hard on the lead wire, or lift the product by holding the lead wires (Tensile strength 49 N or less). Especially never lift the product equipped with fitting and piping by holding the lead wires. Damage to the connector, circuit board, cover or internal components may result, causing failure or malfunction.
- Page 10 Operating environment - Do not use the product in an environment where the product is constantly exposed to water splashes. Otherwise failure or malfunction can result. Take measures such as using a cover. - Do not use in an environment where the product could be exposed to corrosive gas or liquids. Otherwise damage to the internal parts can result, causing malfunction.
- Page 11 * Adjustment and Operation - Connect a load before turning the power supply on. If the power supply is turned on with no load, over current may flow, causing the product to break instantly. - Do not short-circuit the load. Although error is displayed when the product load has a short circuit, generated over current may lead to the damage of the product.

Page 15: Definitions And Terminology
■ Definition and terminology Term Meaning Ambient temperature Ambient temperature range in which the product can operate. range Outputs a value proportional to the flow rate. When the analog output is in the range 1 to Analogue output 5V, it will vary between 1 to 5V according to the rate of flow. The same for analogue output of 4 to -20 mA. -
Page 16: Mounting And Installation
Mounting and Installation Installation - Use the product within the specified operating pressure and temperature range. Withstand pressure is 2.0MPa. Withstand pressure depends on fluid temperature. Refer to the chart of the operating pressure range. Mounting - Never mount the switch in a place that will be used as a scaffold. Mount the product so that the fluid flows in the direction indicated by the arrow on the side of the body. -

Page 18: Piping Method
■ Piping method For piping of the product, hold the piping with a tool on the metal part of the piping (piping attachment). Fixing the product, please turn the pipe. Using a tool on other parts may damage the product. Specifically, make sure that the tool does not damage the M12 connector. -
Page 19: Wiring
■ Wiring Wiring of connector Attaching/detaching of the connector should be done while the power supply is turned off. Use a separate route 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 20 Internal Circuit and Wiring examples Analog output type Analog output type LFE□J□□□ LFE□K□□□ Brown DC(+) Brown DC(+) Black NC Black NC Analog output Analog output White OUT2 White OUT2 DC24V DC24V Load Load Blue DC(-) Blue DC(-) Analog output 4 to 20mA Analog output 1 to 5 V Max.

Page 21: Maintenance
Maintenance and Inspection How to reset the product after a power cut or when the power has been unexpectedly removed The settings of the product are retained from before the power cut or de-energizing. The output condition also recovers to that before power cut or de-energizing, but may change depending on the operating environment. -
Page 22: Troubleshooting
Troubleshooting Troubleshooting Applicable Flow switch: LFE series If an operation failure of the flow switch occurs, please confirm the cause of failure from the flow chart below. If a cause applicable to the failure cannot be identified and normal operation can be recovered by replacement with a new flow switch, this indicates that the flow switch itself was faulty. -
