User manual OMRON E3X-MDA

[. . . ] Digital Fiber Sensor E3X-MDA Series Instruction Sheet Thank you for selecting an OMRON product. This sheet primarily describes precautions required in installing and operating the product. · The specialist who has the knowledge of electricity must treat. · Please often read this manual, and use it correctly after it understands enough. · Please keep this manual importantly to refer at any time. Lit when the output for channel 1 is ON. [. . . ] Press the MODE key for at least 3 seconds. The threshold value that was set will flash twice. Switch to RUN mode. Press the MODE key for at least 3 seconds. . SET mode SET RUN Switch to RUN mode. Press the UP or DOWN key. Press the UP or DOWN key. SET RUN It does not matter whether or not there is a workpiece. The value that is set will depend on the detection method and power adjustment settings. If the output setting is set to 1-2 (differential operation), no threshold setting is possible for channel 2. Switch to RUN mode. · Teaching Error After performing teaching, when the following is displayed on sub digital display, the error has occurred. However, the threshold might not be able to be detected correctly though is set within the possible range. 1. Ratings and Specifications Connection method NPN Model number PNP Light emitting element Supply voltage Power consumption Control output Timer Timer time Power tuning Mutual interference prevention The output will turn ON when the incident light level is below the threshold. Prewired E3X-MDA11 E3X-MDA41 Separate connector*1 E3X-MDA6 E3X-MDA8 Display TECH The sub-display will flash twice. 2PNT Threshold value flash twice. Over error Light level is too large. Do one of the following and then repeat the operation. · Adjust the Head to decrease the incident light level. · Execute power tuning. Red LED 12 to 24 VDC 10%, ripple (p-p) 10% max. at 24 V) Open collector (26. 4 VDC max. ); load current: 50 mA max. ; residual voltage: 1 V max. OFF, OFF-delay, ON-delay, or one-shot 1 ms to 5 s Supported Supported (optical communications sync method)*2 9 Sensors (18 channels)*3 2. Adjusting the Power (as Required) Power tuning can be used to adjust the incident light level that is currently being received to the power tuning target value (default: 2, 000). Before tuning ON the power, always secure the detection object and Head and be sure that the incident light level is stable. The threshold value that was set will flash twice. flash twice. If the output setting is set to 1-2 (differential operation), the value between the two differential values when teaching is performed is used as the threshold setting. Low error Setting Method Confirm that the MODE key setting is PTUN (power tuning) in advance. Refer to Select the channel for power tuning with the channel selector. Switch to RUN mode. SET RUN Light level is too small. Do one of the following and then repeat the operation. · Adjust the Head to increase the incident light level. The difference of incident light level is too small. Do one of the following and then repeat the operation. · Adjust the Head to increase the difference between the two incidentlight levels . Automatic-teaching(It sets up at move work. ) While continuing pushing a key, the middle of the detected maximum and the minimum value can be set up as a threshold. Actual displays may vary. Switch to SET mode. SET RUN A B 6. Convenient Functions Zeroing the Main Display The incident light level displayed on the main display can be zeroed. The threshold displayed in the sub-display is shifted by an amount corresponding to the amount the incident light level was changed. [. . . ] % light level Threshold ---OFF D ON-D Not 1SHT Timer disabled. OFF-delay timer PEAK ON-delay timer One-shot timer Peak level BOTM Alternates at a fixed interval 7. Installing the Amplifier Unit Mounting Units Catch the hook on the Fiber Unit connector end of the Unit on the DIN Track and then press down on the other end of the Unit until it locks into place. Always attach the Fiber Unit connector end first. [. . . ]
