D11E Series Sensors – Visible Green, Blue or White LED Light Source
RUN Mode
Normal operation of the D11 Expert is called RUN mode. The LED indicators operate
in RUN mode, as follows:
Indicator LED Color
Function
SIG
Power
"ON"
Green
1) On steadily whenever power is applied
2) Flashes at approximately 4Hz to indicate that the

output is overloaded

Follows the action of the output:
On when the output is energized
Off when the output is de-energized

Strength
Red
Lights whenever the sensor "sees" its modulated
light source and pulses at a rate which is
proportional to the received light signal strength
The Signal Strength indicator is Banner’s exclusive AID™ (Alignment Indicating
Device, U.S. Patent #4356393). This feature makes alignment during the TEACH mode
easy and accurate and provides a means of signaling when maintenance is needed
when the sensor is in RUN mode. Whenever the pulse rate is slow, the fiber sensing
ends should be cleaned and/or the alignment checked.

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 simply 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 D11E 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 will energize. 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.
