基恩士 ES-M1型长距离放大器、分离型接近传感器 说明书

96M1093 FEATURES ■ One-line connection system See “MOUNTING SEVERAL AMPLIFIERS” on page 2. Separate-amplifier Proximity Sensor A wire-saving sensor system can be established by combining other one-line connection amplifiers such as the FS-V10 Series or LV Series. ES-M1(P)/M2(P) ■ Easy connection with the European terminal Instruction Manual The sensor head is connected to the amplifier through the European terminal, allowing easy and quick connection. See “SENSOR HEAD CONNECTION” on page 1. ■ Disconnection alarm indicator & output See “PART NAMES AND FUNCTIONS” on page 1. The alarm indicator and output turn on when the sensor head is disconnected, enabling quick discovery of abnormal condition. (The ES-M2 features the indicator only.) ■ Mutual interference suppression function See “MUTUAL INTERFERENCE SUPPRESSION” on page 2. Mutual interference among several sensors that are used in close proximity can be suppressed by a simple operation. ACCESSORIES Instruction Manual: 1 Metal screwdriver: 1 Mounting bracket: 1 (ES-M1 only) Read this manual before using the product in order to achieve maximum performance. Keep this manual in a safe place after reading it so that it can be used at any time. SENSOR HEAD CONNECTION 1. Modify the end of the sensor cable as illustrated on the right. Be sure to tightly twist the shield wire and core wire separately. WARNING • The ES-M1/M2 are intended for target detection. Do not use these products in a safety circuit for protecting the human body. • The ES-M1/M2 are not explosion-proof. Do not use these products in an environment where inflammable gas, liquid or powder is present.

Turn the terminal block tightening screws counterclockwise to loosen them. 3. Insert the sensor cable straight into the insertion port of the amplifier. Make sure that the core wire and shield wire are inserted into the correct ports and that the cable does not twist. 4. Turn the terminal block tightening screws clockwise to tighten them. Be sure to limit the tightening torque to 0.15 N•m. 5. Turn ON the amplifier and check that the disconnection alarm indicator remains OFF. If the indicator is ON, go back to step 1 and repeat the procedure again.

With the target removed, again turn the trimmer clockwise and find point B at which the output indicator lights. 3. Set the trimmer midway between points A and B. The output circuit will now actuate when the output indicator lights. The values in parentheses are the values when the mutual interference suppression function is used. HINTS ON CORRECT USE • To extend the sensor head cable, be sure to use a high-frequency coaxial cable and limit the length between the amplifier and sensor head to 10 m or less (5 m when the EH-302/402 is used). Be sure to use an BNC connector (see the table below). Plug Jack BNC-P-1.5 (or equivalent products) BNC-J-1.5 (or equivalent products) MUTUAL INTERFERENCE SUPPRESSION 2 • To extend the amplifier cable, use a cable with at least a 0.3 mm nominal cross-section area. Limit the length of cable extension to no more than 100 m. (To connect several amplifiers, contact KEYENCE for further information.) • If the amplifier cable is placed together with power lines or highvoltage lines in the same conduit, detection error may occur due to noise interference, or the sensor may be damaged. Isolate the amplifier cable from these lines. • When using a commercially available switching regulator, ground the F.G. terminal and ground terminal. • During maximum sensitivity setting, the detecting distance may vary due to the difference in characteristics of each unit. • If the wiring is incorrect, the unit may heat up, or the sensitivity may fluctuate. (See “I/O CIRCUIT DIAGRAM”.) • The EH-422, 430, 440, and 290 sensor heads cannot be connected to the ES-M1/M2. Contact KEYENCE for information on connectable amplifiers. • When installing two or more sensors of the same model face-to-face or in parallel, separate by the distance specified in the following table to prevent interference. The values in parentheses are for when the mutual interference suppression function is used. Distance • Cylindrical type M3 screw (Flat point or cup point) 5 mm min. Secure the sensor head with a screw at a position 5 mm or more from the tip of the head. (Tightening torque: 0.2 N•m max.) • For the EH-402, secure the sensor head to the metal part 15 mm or more from the tip. • Threaded type When mounting the threaded-type sensor head, do not tighten beyond the torque specified in the following table. MOUNTING SEVERAL AMPLIFIERS ■ Mounting several units 1. Remove the protective cover. 2. Mount the amplifiers to the DIN rail one by one. 3. Slide one expansion unit toward another. Align the front claws of the amplifiers and push the amplifiers together until they click. 4. Fix the amplifiers together by pushing the end units toward each end (End units are included with the ES-M2). SURROUNDING METAL Shielded-type sensors can be flush-mounted in a metal base. Sensors of the non-shielded type, however, should be mounted according to the guidelines given below in order to minimize interference from the surrounding metal. Model ■ Detaching amplifiers from DIN rail 1. Remove the end units. 2. Slide the expansion units apart and detach them individually. (Do not detach multiple amplifiers connected together with end units.) øA B 20 30 15 10 B EH-402 EH-416 [Notes] • To connect several units, be sure to use a DIN rail and end units. • To mount or detach several units, be sure to turn the power off. • Do not remove the protective cover of the expansion connector on the outermost unit.
