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.

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.
No. of flashes at end of
TEACH mode

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

of the response of the load or input connected to the sensor output. Turn the pulse stretcher ON or OFF using the following procedure.

3. Enable or disable the 40- millisecond pulse stretcher.
Connect a remote programming switch between the
white wire and dc common (see Hookup Diagrams
on page 4). The switch may be either a normally
open contact, or an open-collector NPN transistor
with its emitter connected to dc common.
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.
The required spacing between adjacent pulses in a
sequence (e.g., a “double-pulse”) is: 0.04 < T < 0.8
seconds. The timing diagrams illustrate the input
requirements.
Figure 9. 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.
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.
