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.

RUN Mode

Normal operation of the D11 Expert is called RUN mode. The LED indicators operate

in RUN mode, as follows:

Function

Power

"ON"

Green

1) On steadily whenever power is applied

2) Flashes at approximately 4Hz to indicate that the

output is overloaded

Yellow

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
