C D10 Expert Fiber-Optic Sensor Analog and Discrete Outputs D10 Expert Description Output 1 Indicator Output 2 Indicator The D10 Expert Sensor is a high-performance plastic fiber-optic sensor whose many configuration (TEACH-mode) options make it suitable for demanding applications. Even with all its features, it is extremely easy to use. Advanced 16-bit microcontroller technology makes this possible. 4-Digit Display The D10 Expert provides high-performance sensing in low-contrast applications, with its Expert TEACH setup with static, dynamic and single-point programming plus manual fine adjustment, remote programming and lockout. Its slender, stylized housing has a large digital display visible beneath a clear cover for easy programming and status monitoring during operation. The sensor mounts directly to standard 35 mm DIN rail or using the supplied mounting bracket. (Mount in a protected area free from excess vibration and wash-down.) The sensor features two outputs with independent set-points: one of two analog choices, depending on model, and one discrete (NPN or PNP, also depending on model). Built-in crosstalk avoidance protocol provides trouble-free operation for multiple sensors in one area.

For remote programming, connect a switch or digital input to the gray wire; length of the individual pulses is equal to the value T: 0.04 seconds T 0.8 seconds Returning to RUN Mode TEACH and SETUP modes each may be exited in one of two ways: by exercising the 60second time-out, or by cancelling out of the process. In TEACH mode, the sensor will return to RUN mode without saving any of the new settings; in SETUP mode, the sensor will return to RUN mode but save all of the settings. To cancel out of TEACH mode, press and hold the Static (-) button for 2 seconds; to cancel out of SETUP mode, press and hold both the Static (-) and Dynamic (+) buttons for 2 seconds. Output 2 The set-point(s) for each output can be set independently of one another. However, the functional range available for output 2 is dictated by the automatic power and gain settings established for output 1. Whenever output 1 is taught, output 2 also must be retaught. Applications hint: teach the weakest signal on output 1 first.

Analog output as a function of target position - single-point TEACH Banner Engineering Corp. * Minneapolis MN, U.S.A. www.bannerengineering.com * Tel: 763.544.3164 Output 1 is configured for either 4 to 20 mA or 0 to 10V dc analog output, depending on the model. The sensor may be programmed using the two-point TEACH (either static or dynamic) or single-point static teach. Teaching two set-points (static or dynamic): The sensor sets the first taught condition to the highest output level (either 20 mA or 10V), and the second taught condition to the lowest level (either 4 mA or 0V), and scales between these points. If the first condition taught has more returned light, the sensor will be in Light Operate mode (LO). If the first taught condition is darker, the sensor will be in Dark Operate mode (DO). To change the slope of the analog output (refer to Figure 2), toggle LO/DO in Setup (page 6). Single-point (static) Teach: The sensor sets the taught condition to the mid-point of its range (12 mA or 5V, depending on the model). For Light Operate mode, the sensor will automatically scale up to 20 mA (or 10V) for maximum light condition (the maximum possible received signal) and down to 4 mA (or 0V) for maximum dark condition (no signal), and vice-versa for Dark Operate mode. To change the slope of the analog output (refer to Figure 3), toggle LO/DO in Setup (page 6). An OFF-delay enabled for the analog output acts as an averaging function. During the OFF-delay period, the sensor will take multiple analog readings and average the result before changing the analog value. This acts to reduce the effects of major spikes in the analog system, in effect "smoothing" the output reading. NOTE: Depending on the application configuration and fibers used, the analog function may or may not behave linearly. The received light intensity will be dictated by the inverse square properties of light. page 9 D10 Expert Fiber-Optic Sensor Analog and Discrete Outputs Dynamic TEACH and Adaptive Thresholds Dynamic TEACH is used to program sensitivity during actual machine run conditions. During Dynamic TEACH, the D10 takes multiple samples of the light and dark conditions and automatically sets the sensitivity at the optimum level. For the discrete output, Dynamic TEACH activates the sensor's adaptive threshold system, which continuously tracks minimum and maximum signal levels, and automatically maintains centering of the switch point between the light and dark conditions. The adaptive threshold system remains in effect during RUN mode to automatically adjust for changes in the light or the dark conditions. The adaptive routine saves to nonvolatile memory at least once per hour. When Dynamic TEACH mode is used to program sensitivity, the output ON state (light or dark operate) will remain as it was last programmed. To change to either light or dark operate, use the SETUP mode (see page 6). Sensitivity may be adjusted at any time when the sensor is in RUN mode by clicking the "+" and "-" buttons. However, when a manual adjustment is made, the adaptive threshold system is disabled (cancelled). Self-Diagnostic Error Modes In the unlikely event that the setup parameters are lost or become corrupt, the display will continuously scroll: "E2 Error." Reteach the sensor to recover. If the problem persists, contact your Banner representative for further information. Gate Input The D10's pink wire is configured as a gate input. When this wire is pulled low (i.e., to the sensor ground), it inhibits the discrete output from switching, while all other D10 functions continue to be enabled. This feature is useful for controlling when the outputs are allowed to change states. Gate input function response time is 1 millisecond. While the gate is enabled, the analog output holds the last value. Repairs NOTE: Do not attempt any repairs to the D10. It contains no field-replaceable components. Return the sensor to the factory for warranty repair or replacement. If it ever becomes necessary to return a D10 to the factory, please do the following: 1) Contact the Banner Factory Application Engineering Group at the address or at the numbers listed at the bottom of the back page. They will attempt to troubleshoot the system from your description of the problem. If they conclude that a component is defective, they will issue an RMA (Return Merchandise Authorization) number for your paperwork, and give you the proper shipping address. 2) Pack the D10 carefully. Damage which occurs in return shipping is not covered by warranty. page 10 Banner Engineering Corp. * Minneapolis MN, U.S.A. www.bannerengineering.com * Tel: 763.544.3164 D10 Expert Fiber-Optic Sensor Analog and Discrete Outputs Dimensions Slide Up to Release Fibers 7.6 mm (0.30") 61.3 mm (2.42") 10.0 mm (0.39") Mounting Bracket (included) 35.9 mm (1.41") 68.1 mm (2.68") 8.6 mm (0.34") 10.0 mm (0.39") 9.8 mm (0.39") 5.0 mm (0.20") 5.0 mm (0.20") 2x 3.5 mm (0.14") 2.5 mm (0.10") 35.1 mm (1.38") Plastic Fiber Emitter Port 25.4 mm (1.00") 16.0 mm (0.63") 15.2 mm (0.60") Plastic Fiber Receiver Port 2 x o3.3 mm (0.13") 2x o3.2 mm (0.13") 10.0 mm (0.39") 2x C'sink o8.0 mm (0.31") 3.2 mm (0.13") deep o4.4 mm (0.18") thru Hookups D10INFP(Q) bu bu - 12-24V dc + bn bk wh D10UNFP(Q) - 15-24V dc + bn Load 2 bk 4-20 mA 1 wh gy pk Teach gy Gate pk D10IPFP(Q) bn wh bk Gate bn 1 wh Load 2 bk pk + 15-24V dc - bu 4-20 mA gy 1 Teach D10UPFP(Q) + 12-24V dc - bu 2 Load 0-10V dc Teach gy Gate pk 0-10V dc 1 Load 2 Teach Gate NOTE: QD Hookups are identical.
