User manual OMRON E3U-GL DATASHEET

[. . . ] The label length and the label interspace must be >2 mm Suitable for label thickness <0. 9 mm. 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). [. . . ] 2s The auto-teach procedure is now active indicated by a fast flashing Status LED. 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. The sensor automatically switches into run mode. · 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 not connected the sensor operates in run mode. 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. Excess voltage may result in malfunction or fire. Never use the product with an AC power supply. 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. (4) Do not pull on the cable with excessive force. [. . . ] 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. [. . . ]
