Maximum Range (Diffuse mode performance based on 90% reflectance white test card)
Range varies by sensing mode and fiber optics used:
• PIT46U fibers, opposed mode: 180 mm (7.1")
• PIT26U fibers, opposed mode: 50 mm (2.0")
• PBT46U fiber, diffuse mode: 50 mm (2.0")
• PBT26U fiber, diffuse mode: 10 mm (0.4")
Standard 2 m (6.5 ft) cable models are listed. To order the 9 m (30 ft) cable model, add suffix "W/30" to the cabled model number. For example, D11EN6FP W/30. Models with a QD connector require a mating cable. (See Accessories).
WARNING: Not To Be Used for Personnel Protection Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or death. This device does not include the self-checking redundant circuitry necessary to allow its
use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de­energized sensor output condition.

Indicators
Three LEDs: Green, Yellow and Red Green LED lights for dc power ON and flashes when
ready to register sensing condition during TEACH mode: 1 Hz when waiting to learn first sensing condi­tion; 2 Hz when waiting to learn second sensing condi­tion; 4 Hz when output is overloaded.
Yellow LED lights for output ON (conducting). Red LED is Banner’s patented Alignment Indicating
Device (AID, U.S. patent #4356393) which lights whenever the sensor “sees” a light condition and su­perimposes a pulse rate which is proportional to the strength of the received light signal (the stronger the signal, the faster the pulse rate).

The Signal Strength indicator is Banner’s exclusive AID (Alignment Indicating Device
). 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.
Perform the following procedures 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.) 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.
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.

NOTE: If the relative contrast level is unacceptable (1 flash), the program will return to TEACH condition #1.
