Push Button

Indicator Status

Push and hold 2 seconds or longer -
Current output settings are displayed

Change from Run mode to
Output Configuration (Display)
mode

Two steady red LEDs indicate the output settings: light or dark operate and
output timing (0 or 40ms).
The sensor continues to operate normally during the display period. The dis-
play automatically returns to Run mode if the button is not pushed within 10
seconds.

Double-click - ON indicator (green
LED) single-flashes at 1 Hz.

Change to TEACH mode

Green ON LED single-flashes at 1Hz and the 7-segment display indicates
relative received signal strength.
There is no timeout for the TEACH mode sequence. To escape from TEACH
mode and return to Run mode with the previous setting, press and hold the
button for 2 seconds or longer.

TEACH Condition #1 - Present the
first condition to the sensor and sin-
gle-click the push button

When the push button is single-clicked, the 7-segment display turns each of
its LEDs ON in sequence from #7 to #1, as the sensor samples and registers
the first condition. The green ON LED double-flashes at 1 Hz to indicate the
sensor is ready to learn the second condition.
There is no timeout for the TEACH mode sequence. To escape from TEACH
mode and return to Run mode with the previous setting, press and hold the
button for 2 seconds or longer.

TEACH Condition #2 - Present the
second condition to the sensor and
single-click the push button

When the push button is clicked, the 7-segment display will turn each of its
LEDs ON in sequence from #7 to #1, as the sensor samples and registers
the second condition. The 7-segment display will then flash 1 to 7 of its LEDs
three times to indicate relative sensing contrast. (See Figure 4, above right.)
If the contrast is acceptable, the sensor returns (after a few seconds) to RUN
mode with the new, optimized sensitivity setting. If the contrast is unaccepta-
ble (indicated by only #1 LED of the 7-segment display flashing three times),
the sensor returns to TEACH mode condition 1.
If the contrast is unacceptable, the ALARM output also pulses three times.

Remote Programming

To remotely program the TEACH and Output Configuration modes, connect the sensor’s gray wire to a remote programming switch. (This
input parallels the push button on the sensor, so the push button sequences explained in

Output Configuration Programming

on page 6

and

Contrast Indication

on page 6 also apply for a remote switch.)

Connect a remote programming switch between the gray wire and dc common (see

Wiring Diagrams

on page 3). The switch may be

either a normally open contact, or an open-collector NPN transistor.
The timing diagrams define single-, double-, and triple-click, simulating the D12 Expert’s programming push button. The ON time of each
click must be at least 40 milliseconds. The minimum space between clicks must be at least 40 milliseconds. The total time of two adja-
cent clicks of a double- or triple-click must be less than 800 milliseconds. Conversely, there must be at least 800 milliseconds between
the start of a single- or double-click and the next input.
