If no echo is received by the sensor, the target is assumed to be beyond the far window limit.

Sensor Programming
Window limits may be taught to the sensor using the push buttons on the back of the sensor or using remote programming.
NOTE: When the sensor changes state between Program and Run modes, all of the LED indicators turn OFF momentarily, before the
appropriate LEDs turn ON. The sensing window limits expand temporarily to full scale (max range) during Program mode.
Program the outputs independently to define separate sensing windows (both their size and placement) or program the outputs simultaneously for complementary opera-
tion. Sensing windows may be as large as 0.85 m for 1 m range models, and 1.7 m for 2 m range models. Note: Output 1 = White wire (Pump-Out), Output 2 = Black wire
(Pump-In).
General Notes on Programming:
1. The sensor returns to Run mode if the first TEACH condition is not registered within 120 seconds.
2. After the first limit is taught, the sensor remains in Program mode until the TEACH sequence is finished.
3. Press and hold the programming push button > 2 seconds (before teaching the second limit) to exit Program mode without saving any changes. The sensor will
revert to the last saved program.
Remote Programming
Use the Remote Programming function to program the sensor remotely or to disable the keypad, Disabling the keypad prevents anyone from adjusting any of the program-
ming settings directly from the sensor. Connect the gray wire of the sensor to +12 to 24V dc, with a remote programming switch connected between them.
NOTE: The impedance of the remote teach input is 55 kΩ.
Follow the sequence of input pulses to program the sensor. The duration of each pulse (corresponding to a push button “click”), and the period between multiple pulses, is
defined as: 0.04 seconds < T < 0.8 seconds.
NOTE: Hold the Remote line high > 2 seconds (before teaching the second limit) to exit Program mode without saving any changes. The
sensor will revert to the last saved program.
