User manual OMRON E3U-GL DATASHEET

[. . . ] The label length and the label interspace must be >2 mm Note: The actual minimum values depend on the combination of material, interspace between labels and label thickness and length. 2 Label Sensors Operation 1. E3U-GL1 / E3U-GL2 Installation: Connect the sensor to the operating voltage (+). Place the label material in the correct position (the detection beam spot is indicated by marks in the housing). During the teach process do not remove the label material from the detection area. Remote auto-teach (E3U-GL1 only): For remote auto-teach connect pin 2 (white wire) to the operating voltage (+). [. . . ] The auto-teaching takes 2-10 seconds depending on the complexity of the labels. For higher stability the number of labels that are pulled through should be as high as possible. The result of the auto-teach procedure is indicated by the Status LED and Power LED: · Status LED and power LED flashing 2x: auto-teach procedure successful. · Status LED and power LED flashing 4x: Auto-teach procedure not successful. Repeat the auto-teach procedure. Remote auto-teach: For remote auto-teach connect pin 2 (white wire) to the operating voltage (+). The result of the remote auto-teach procedure is indicated by the Status LED and Power LED as described before. If pin2/white wire is connected to ground the sensor is locked (no manual auto-teach possible) 4 Label Sensors Output Circuit Diagram E3U-GL1-M3 1 Brown 10 to 35VDC NPN Teach 2 Lock PNP 0V M8 Connector Pin Arrangement 2 1 4 3 E3U-GL2-M3 1 Brown 10 to 35VDC NPN 2 4 3 White Black Blue White Black Blue 4 3 PNP 0V E3U-GLK31-M1 E3U-GLK32-M1 1 Brown 10 to 35VDC NPN Teach 4 2 3 Black White Blue PNP 0V Lock M12 Connector Pin Arrangement 1 2 3 4 E3U-GL 5 Dimensions E3U-GL1-M3 M8 x 1 Status LED yellow Teach 29, 5 35 E3U-GL2-M3 Teach 5 19 11 100 NO/NC Status LED 14 5 Status LED M5 102, 5 M8x1 120 Power LED green E3U-GLK31-M1 Teach E3U-GLK32-M1 Teach M3 x 10 max. 0, 8 Nm Power LED Status LED Power LED Status LED 6 Label Sensors 12 28 5 Safety precautions !Warning This product is not designed or rated for directly or indirectly ensuring safety of persons. Do not use it for such a purpose. Precautions for Correct Use Do not use the Sensor in any atmosphere or environment that exceeds the ratings. Do not install the Sensor in the following locations. (1) Locations subject to direct sunlight (2) Locations subject to condensation due to high humidity (3) Locations subject to corrosive gas (4) Locations where the Sensor may receive direct vibration or shock !Caution Do not use the product with voltage in excess of the rated voltage. Otherwise, explosion may result. Connecting and Mounting (1) The maximum power supply voltage is 35 VDC. Before turning the power ON, make sure that the power supply voltage does not exceed the maximum voltage. (2) Laying Sensor wiring in the same conduit or duct as high-voltage wires or power lines may result in malfunction or damage due to induction. As a general rule, wire the Sensor in a separate conduit or use shielded cable. (3) Use an extension cable with a minimum thickness of 1 mm2 and less than 100 m long. (5) Pounding the Sensor with a hammer or other tool during mounting will impair water resistance. (6) Be sure to turn OFF the power supply before inserting or removing the connector. When cleaning the product, do not apply a high-pressure spray of water to one part of the product. Otherwise, parts may become damaged and the degree of protection may be degraded. High-temperature environments may result in burn injury. Power Supply Precautions for Safe Use The following precautions must be observed to ensure safe operation of the Sensor. If a commercial switching regulator is used, ground the FG (frame ground) terminal. Turning OFF the Power Supply Output pulses may be generated even when the power supply is OFF. Therefore, it is recommended to first turn OFF the power supply for the load or the load line. Operating Environment Do not use the Sensor in an environment where explosive or flammable gas is present. Load Short-circuit Protection This Sensor is equipped with load short-circuit protection, but be sure to not short circuit the load. Be sure to not use an output current flow that exceeds the rated current. Connecting Connectors Be sure to hold the connector cover when inserting or removing the connector. [. . . ] CHANGE IN SPECIFICATIONS Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made. However, some specifications of the product may be changed without any notice. When in doubt, special model numbers may be assigned to fix or establish key specifications for your application on your request. [. . . ]
