The following description provides information on the automatic teaching of the E2C-T for sensitivity adjustment. Teaching Proximity Sensor with Separate Amplifier Teaching with no sensing target (Used for normal object detection) 2 1 Set the mode selector to T. Set the mode selector to RUN. (See Note 5.) T ON point T Without sensing target TEACH RUN The ON point is automatically adjusted in the vicinity of the maximum stable sensing range. RUN Press the TEACH button once. 2 1 Teaching with and without sensing target (See Note 3.) (Used for level difference detection and plate overlapping detection) 3 Set the mode selector to T. (See Note 5.) T With lower-side level detected T With upper-side level detected TEACH The ON point is set in the middle of the levels. TEACH RUN RUN Press the TEACH button once. Positioning teaching (See Note 4.) (Used for detection of objects too close to the Sensor with ON point specified) ON point Set the mode selector to RUN. Press the TEACH button once. (2nd time) 2 1 Be sure to take steps 1 and 2 in numerical order. 3 Set the mode selector to RUN. Set the mode selector to T. (See Note 5.) T Without target object With target object located in ON position TEACH RUN With target object located in the same position. TEACH Press the TEACH button once. Press the TEACH button once. (2nd time) TEACH T RUN Press the TEACH button once. (3rd time) 4 The ON point is set to the teaching position. ℓ ON point Be sure to take steps 1 and 2 and 3 in numerical order. Note: 1. Refer to details in the Sensitivity Setting (Automatic Teaching) section of this data sheet. 2. Before use, be sure to perform the teaching of the E2C-T. 3. If a fine-difference teaching is performed, reset failures may result when the E2C-T is in operation even if the teaching is successful. Make sure that the E2C-T resets smoothly after the teaching. 4. Be sure to perform positioning teaching within the stable sensing distance range, or reset failures may result -- even if teaching is successful. Be sure to check that the E2C-T can be reset after teaching. Refer to Ratings for the stability sensing range. 5. No transistor output will be ON if the mode selector is set to T, and a wrong signal may be output. The utmost attention is required for positioning teaching. 9 E2C-T E2C-T Sensitivity Setting (Automatic Teaching) in Detail Type of teaching Teaching without a target object Procedure 1.

Once the teaching of the E2C-T is performed, the teaching data set in the E2C-T will be retained even after turning OFF the E2C-T. 10 E2C-T E2C-T Precautions J POWER SUPPLY VOLTAGE J INCORRECT WIRING Do not impose voltage exceeding the rated voltage range or 100 VAC on the E2C-T, to avoid damaging the E2C-T. To avoid damaging the E2C-T, observe the correct polarity when connecting the power supply and the load to the E2C-T. Load Brown Sensor Brown Load Black Sensor Blue Black Blue J LOAD SHORT-CIRCUITING Do not short-circuit the load, or the E2C-T may be damaged. The load short-circuit protection function is triggered provided that power within the rated voltage range is supplied to the E2C-T without a mistake in polarity. Brown Sensor Black Load Brown Sensor Load Blue Black If a set screw is used for mounting a screwless, column model, make sure that the tightening torque does not exceed 0.2 N S m (2 kgf S cm).

The mutual interference of the Sensors can be prevented by cable length selector settings. However, the result is a change in the coil characteristics of the Sensors, and the specified ratings may not be satisfied in all permissible temperature or sensing distance ranges. Test the operation of the Sensors before using them in an actual application. See Note 1. Sensor cable 5 (0.20) If more than one Sensor is located face-to-face or in parallel, be sure to maintain enough space, (as provided in the following diagram), between adjacent Sensors, to suppress mutual interference. See Note 2. 2.5 4 to 5 Note: The cable length of E2C-CR5B2 cannot be adjusted, so mutual interference cannot be manipulated for this sensor using cable length selector settings. 7 to 8 14 max. Note: 1. Be sure to turn over the braided shield, so that none of its thin wires are left. 2. Make sure that the insulation distance of at least 2.5 mm is maintained. 20 (0.79) 15 (0.59) J INFLUENCE OF SURROUNDING METAL If the Sensor is embedded, be sure to separate the Sensor from surrounding metal objects, as shown in the following illustration. d dia.
