Mutual Interference Prevention The E4PA-N provides a sync input to prevent mutual interference. When the fifth pin of the Sensor I/O Connector’s M12 Connector is interconnected, mutual interference can be prevented for up to five Units. The Sensors will mutually oscillate, however, causing a delay in measurement time by the mutual interference cycle time per Sensor × number of Units + response time. When the sync inputs are not connected, the mutual interference prevention function is disabled. (For example, if three E4PA-LS200-M1-N are connected, the response time for one Sensor is 34 ms × 3 Sensors + 195 ms = 297 ms. 4 E4PA-N Ultrasonic Displacement Sensor Operation Setup and Operating Procedure The E4PA-N is factory-set for the decrease mode for analog output characteristics and for the maximum sensing range. These settings enable scaling with the connected device (e.g., the K3NX). In this case, only step 4 is required. To change the analog output range, follow steps 1 to 4 below. 1. Preparation for Setup Step 1 3. Setting Analog Output Characteristics Mode Setting/Operation Remove the Setting Plug. Step 1 2 Turn ON the power. (See note.) 3 Proceed to Step 2 Setting Sensing Range. Note: Do not insert the Setting Plug yet. It must be inserted within five minutes after the power is turned ON, however, or the setup will not be possible. If that happens, power up again and start over. A2 RUN indicator (yellow) flashing: ● Analog output characteristics: Decrease mode In this mode, the analog output decreases (20 to 4 mA/10 to 0 V) as the E2 sensing object nears the E4PA within the sensing range. A1 A2 2. Setting Sensing Range Step 1 A1 RUN indicator (yellow) flashing: ● Analog output characteristics: Increase mode In this mode, the analog output increases (4 to 20 mA/0 to 10 V) E3 E2 as the sensing object nears the E4PA within the sensing range. A1 A2 Insert the Setting Plug at the A1 position. (Align the notch on the Sensor with the A1 triangular mark on the Setting Plug.) The power indicator (green) and the A1 RUN indicator (yellow) with flash, showing that the near distance has been correctly set. The mode changes when the Setting Plug is reinserted at the E2/E3 position. A1 position A1 and A2 RUN indicators (yellow) flashing at the same time: ● Analog output characteristics: Output from 0 mm In this mode, the analog output decreases (20 to 4 mA/10 to 0 V) as the sensing object nears the E3 E2 E4PA between the farthest sensing point and 0 mm. A1 A2 E3 E2 A1 A2 3 Remove the Setting Plug. (In this state, the setting is confirmed and recorded.) 4 Place the sensing object at the farthest point within the sensing range. Sensing object Note: Check the input impedance of connected devices and the analog output in Ratings/Characteristics (see page 2). 500 mm (for E4PA-LS50-M1-N) Insert the Setting Plug at the A2 position. (Align the notch on the Sensor with the A2 triangular mark on the Setting Plug.) The power indicator (green) and the A2 RUN indicator (yellow) will flash, showing that the far distance has been correctly set. 6 7 E3 The mode changes when the Setting Plug is reinserted at the E2/E3 position. 50 mm (for E4PA-LS50-M1-N) 5 E2/E3 position Setting/Operation Place the sensing object at the nearest point within the sensing range. Sensing object 2 Setting/Operation Insert the Setting Plug at the E2/E3 position. (Align the notch on the Sensor with the E2/E3 triangular mark on the Setting Plug.) 2 After the analog output characteristics have been set, remove the Setting Plug. 3 Proceed to Step 4 Setting Temperature Compensation Mode. A2 position E3 E2 A1 A2 Remove the Setting Plug. (In this state, the setting is confirmed and recorded.) 4. Setting Temperature Compensation Mode Step 1 Proceed to Step 3 Setting Analog Output Characteristics Mode. 2 Setting/Operation Insert the Setting Plug at the T position. (Align the notch on the Sensor with the T triangular mark on the Setting Plug.) T position Leave the Setting Plug inserted where it is. (This completes the setup.) Note: To maintain the temperature compensation, leave the Setting Plug inserted during operation. If it is removed from the E4PA, the temperature compensation will be disabled. Note: If the reflection from the Sensor is extremely weak, or if the sensing object is set outside of the sensing range, the error indicator (red) will flash to show that the sensing range is not accurately set. If the Setting Plug is left removed for five minutes or longer, temperature compensation will be disabled (status before setting). If it becomes necessary to change the settings for step 2 (Sensing Range) or step 3 (Analog Output Characteristics Mode) after steps 1 through 4 have been completed, the contents of all the previous settings will be remembered, so only the items to be changed need to be reset. Go through the steps in order, from 1 to 4, and reset only the items to be changed. E4PA-N Ultrasonic Displacement Sensor 5 Safety Precautions ■ Precautions for Safe Use Facing Arrangement E4PA-N Design E4PA-N Power Supply X If possible, use a power supply without overcurrent detection. This Sensor uses a DC-DC converter in the power supply circuit. If the power supply has overcurrent detection, the protective circuit may be activated by the inrush current. Recommended power supply: OMRON S82-series Power Supply (Capacity: 15 W min.) Wiring Model E4PA-LS50-M1-N Y 2 m min. E4PA-LS200-M1-N 8 m min. E4PA-LS400-M1-N 16 m min. E4PA-LS600-M1-N 25 m min. Sensing Object Power Supply Voltage Do not exceed the operating voltage range. Using a higher voltage or using an AC power supply (100 VAC or more) for a DC Sensor can cause explosion or burning. Faulty Wiring Be careful not to make wiring mistakes such as reversing the power supply polarity. Faulty wiring can cause explosion or burning. Operating Environment Do not use the Sensor in an environment where inflammable or explosive gas is present. Others • Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock. • Dispose of Sensors as industrial waste. ■ Precautions for Correct Use • The sensing object may be solid, liquid, or powder, and the detection capability of the Sensor will vary depending on the surface conditions of the object. If the surface irregularities are no more than 0.2 mm, then the specified sensing distance will apply. Materials such as fine powder, felt, cotton, and other materials that absorb sound should be tested before using the Sensor. • If the surface temperature of the sensing object is over 100°C, there will be very little ultrasonic reflection. Conduct tests before using the Sensor. Influence of Sensing Angle Ultrasonic Displacement Sensors can detect solid, liquid, or powder sensing objects, but the surface of the sensing object will affect the measurement. Dented surfaces or sensing objects with an angled surface require a tilt angle within 3° max. to achieve accurate sensing. E4PA-N Sensing object Design 3° Sensor Ambient Temperature and Humidity The acoustic velocity generally fluctuates approximately 0.17% with each 1°C of temperature change. For example, if the ambient temperature increases from 20 to 40°C, then the acoustic velocity will increase by 3.5%. Moreover, the acoustic velocity will increase by 2% in dry air compared with air with 100% humidity. Test the environmental conditions where the Sensor will actually be used. Mutual Interference 3° Installation Mounting the Sensor The Sensor must be mounted using the nuts provided, and tightened to a torque of 15 N·m max. If the Sensor malfunctions due to noise, insert insulation between the Sensor and the mounting base (metal). The mutual interference prevention function can be used with up to five Sensors in close proximity. Separate the Sensors as specified in the following table when using two or more Sensors in close proximity without using the mutual interference prevention function. Atmosphere Parallel Arrangement • Ultrasonic sensors use air as the transmission medium, so if there are local temperature differences there may be malfunctioning due to reflection and refraction at the boundaries, and the detection distances change where wind blows. Therefore, the Sensor should not be used near equipment such as forced-air ventilators. Sensing object E4PA-N E4PA-N Y Sensing object • To ensure reliability and long service life, do not use the Sensor outdoors or in places that exceed the rated temperature. • Jets from air nozzles include various frequencies, so they can affect the Sensor and should not be used nearby. • Water drops on the Sensor surface shorten the sensing distance. Note: The values shown in the following table are examples for reference only. The actual values will vary depending on the surface conditions of the sensing object, and on the ultrasonic waves that are reflected. Moreover, if the sensing object is inclined, the Y value in the table will be increased further. Model Y E4PA-LS50-M1-N 0.3 m min. E4PA-LS200-M1-N 1 m min. E4PA-LS400-M1-N 2 m min. E4PA-LS600-M1-N 2.5 m min. 6 E4PA-N Ultrasonic Displacement Sensor Wiring Considerations Cable Length The cable must be no longer than 10 m. High-voltage Lines Do not lay power supply cable for the E4PA-N Ultrasonic Displacement Sensor together with high-voltage lines or power lines. Placing them in the same conduit or duct may result in interference, damage, or malfunction. Dimensions Note: All units are in millimeters unless otherwise indicated. ■ Sensors E4PA-LS50-M1-N M30 × 1.5 Two clamping nuts 5 Setting Plug Indicator (See note.)
