Green, Yellow, and Red indicators flash
simultaneously one to four times to indicate relative
sensing contrast (see chart, above).
After a few seconds, the sensor returns to the
RUN mode
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 forgivingness to subtle changes in sensing
conditions. The display of contrast at the end of the TEACH mode is as follows:
Note: If the relative contrast level is unacceptable (1 flash), the program will return to
TEACH Condition #1.

TEACH MODE Programming
Maximum Sensitivity Setting
D11E 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 the TEACH mode, and then clicking the push button four times in a row.
NOTE: the default program includes light operate output and pulse stretcher "off".
†
NOTE: The sensor will return 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 holding the push button depressed for 2 seconds.
