The LED indicators operate in Run mode, as follows: Indicator LED Color 1 Signal Strength (SIG) Red 2 Output Amber Follows the action of the output: • On when the output is energized • Off when the output is de-energized 3 Power ON Green Solid when power is applied. 4 Button n/a 1 Lights when the sensor sees its modulated light source and pulses at a rate proportional to the received light signal strength. Flashes at approximately 4 Hz to indicate the output is overloaded 2 3 Function Programming push button 4 The Signal Strength indicator is Banner’s exclusive AID™ (Alignment Indicating Device 3). This feature simplifies accurate alignment during TEACH mode and provides a means of signaling when maintenance is needed during Run mode. When the pulse rate is slow, clean the fiber sensing ends and check the alignment. Maximum Sensitivity/Factory Defaults The sensors are factory-programmed for maximum sensitivity. This default setting may be easily recalled by holding the push button for two or more seconds to enter TEACH mode, and then clicking the push button four times in a row. The default program also is set for light operate output and pulse stretcher OFF, push button enabled. 3 U.S. Patent #4356393 2 www.bannerengineering.com - Tel: +1-763-544-3164 P/N 44279 Rev. D D11 Expert Series Perform the procedures in this document to program your own settings. TEACH Mode Sensitivity is automatically set (and optimized) by teaching the sensor the light and dark conditions. This is accomplished in TEACH mode. TEACH mode requires that each of the two sensing conditions be presented to the fiber optics; when the push button is clicked, the sensor samples the sensing condition and registers it into memory. After the second sensing condition is registered, the D11 Expert automatically sets the sensitivity to the optimum value for the application, and then returns to Run mode. Note: There is a period of a few seconds at the end of TEACH mode, before Run mode begins. Light or Dark Operate Selection The two sensing conditions may be presented in either order: the light condition first, and then the dark condition, or vice versa. The condition presented first is the condition for which the output energizes. In other words, the output will be light operated if the light condition is TEACH condition #1, or the output will be dark operated if the dark condition is TEACH condition #1. Max. Light Signal Light Sensing Condition D11E sensors automatically set to a point just above the dark condition for the best performance in low contrast sensing applications; D11E2 sensors automatically set to a point midway between the dark and light conditions, to ignore subtle changes, such as web flutter. Threshold for D11E2 (e.g. = 1x) Dark Sensing Condition Threshold for D11E (e.g. = 1x) Min. Light Signal Contrast Indication When the push button is clicked to teach the second sensing condition, the three LED indicators flash simultaneously to indicate relative sensing contrast. Contrast is the difference in light level between the two sensing conditions. Higher contrast allows higher sensitivity level, and resulting higher excess gain. A high contrast level is directly related to sensing reliability, and is more forgiving of subtle changes in sensing conditions. The contrast display at the end of TEACH mode is shown, at right. Table 1: Contrast Indication Number of flashes at end of TEACH mode Relative Contrast 1 Unacceptable 2 Low 3 Moderate 4 High Note: If the relative contrast level is unacceptable (1 flash), the program returns to TEACH condition #1. TEACH Mode Programming 1. Action Result Green LED: Flashes at 1 Hz Press and hold the button for more than 2 seconds. Amber LED: Off Red LED: Pulses to indicate relative received signal strength 2. TEACH Condition #1 (output ON state). Action Result a. Present the first sensing condition to the sensor. Green: Flashes at 2 Hz b. Single-click the button. 4 Amber: OFF This condition corresponds to the sensor output ON state. Red: Pulses to indicate relative received signal strength 3. TEACH Condition #2 (output OFF state). 4 The sensor returns to RUN mode if the first TEACH condition is not registered within 20 seconds. TEACH mode may be cancelled before either condition #1 or #2 by pressing the push button for more than 2 seconds. P/N 44279 Rev. D www.bannerengineering.com - Tel: +1-763-544-3164 3 D11 Expert Series Action Result a. Present the second sensing condition to the sensor. b. Single-click the button. Green, amber, and red indicators flash simultaneously one to four times to indicate relative sensing contrast (see Table 1 on page 3) . This condition corresponds to the sensor output OFF state. After a few seconds, the sensor returns to RUN mode. Output Pulse Stretcher A 40 millisecond pulse stretcher (OFF-delay) may be enabled for applications where a very short sensing event might be missed because of the response of the load or input connected to the sensor output. Turn the pulse stretcher ON or OFF using the following procedure. 1. Action Result Green LED: Flashes at 1 Hz Amber LED: Off Press and hold the button for more than 2 seconds. 2. 3. Red LED: Pulses to indicate relative received signal strength Action Result a. Double-click the button to display status. Pulse Stretcher ON Green: Off Amber: Off Red: Solid on b. Single-click the button to toggle pulse stretcher ON or OFF. Pulse Stretcher OFF Green: Off Amber: Off Red: Double-flash Action Result Double-click the button to save the configuration and return to Run mode. See Run Mode on page 2 Remote Programming Connect the D11 Expert's white wire to a remote switch for three sensor programming functions: 1. Disable or enable the push button 2. TEACH mode programming of sensitivity 3. Enable or disable the 40-millisecond pulse stretcher. Connect a remote programming switch between the white wire and dc common (see Wiring Diagrams on page 2). The switch may be either a normally open contact, or an open-collector NPN transistor with its emitter connected to dc common. 0.04 sec T < 0.8 sec T Single-Pulse Input Wait > 0.8 seconds before next input T Program the sensor using a specified sequence of input pulses. The duration of each pulse is defined as: 0.04 seconds < T < 0.8 seconds. T Two-Pulse Input Wait > 0.8 seconds before next input T The required spacing between adjacent pulses in a sequence (for example, a double-pulse) is: 0.04 < T < 0.8 seconds. The timing diagrams illustrate the input requirements. T T T T Four-Pulse Input T T T Wait > 0.8 seconds before next input Figure 3. Timing Programs Disable or Enable the Push Button When remote programming is used exclusively, it may be beneficial to disable the push button on the D11E to increase the security of the settings. 1. To disable the push button: Pulse the remote input four times. 2. To enable the push button at a later date: Pulse the input four times (again). Note: The push button can be enabled and/or disabled via remote line only. 4 www.bannerengineering.com - Tel: +1-763-544-3164 P/N 44279 Rev. D D11 Expert Series Set Sensitivity Via TEACH Mode 1. Present the first (output ON) sensing condition to the sensor and pulse the remote input once. 2. Present the second (output OFF) sensing condition to the sensor and pulse the remote input once. The three LED indicators flash simultaneously one to four times to indicate relative sensing contrast. The sensor returns to RUN mode. Enable or Disable the 40-millisecond Pulse Stretcher 1. Pulse the remote input two times. The status of the pulse stretcher is indicated by the red LED: ON if the pulse stretcher is ON, and double-flash if the pulse stretcher is OFF. 2. Pulse the remote input once to toggle the pulse stretcher ON or OFF. 3. Pulse the remote input two times to save the setting and return to Run mode.
