Sensor Configuration
Sensor configuration is accomplished through TEACH or Set options, plus Setup mode. After TEACH or Set have defined the sensing
parameters, Setup mode may be used to enable the delay, to change the Light Operate/Dark Operate status, or to select the high-speed
response option (HS). Manual Adjust may be used to fine-tune the thresholds (see
Bar Graph Indicator Functions on page 8). Two
push buttons, Dynamic (+) and Static (-), or the remote wire, may be used to access and set the parameters.
Sensor configuration options include:
• Two-Point Static TEACH: a single switching threshold, determined by two taught conditions.
• Dynamic (on-the-fly) TEACH: a single switching threshold, determined by multiple sampled conditions.
• Window Set: a sensing window, centered on a single sensing condition.
• Light Set and Dark Set: a single switching threshold, offset from a single sensing condition.
Remote Configuration
The remote function may be used to configure the sensor remotely or to disable the push button for security. Connect the gray wire of the
sensor to ground (0V dc), with a remote programming switch connected between them. Pulse the remote line according to the diagrams
in the configuration procedures. The length of the individual programming pulses is equal to the value T where: 0.04 seconds ≤ “T” ≤ 0.8
seconds
Returning to Run Mode
Configuration modes each may be exited either after the 60-second time-out or by exiting the process in one of the two following ways:
• In static TEACH or SET modes, press and hold the Static (-) button (or hold the remote line) for 2 seconds. The sensor returns to Run
mode without saving any new settings.
• In SETUP mode, press and hold both the Static (-) and Dynamic (+) buttons (or hold the remote line) for 2 seconds. The sensor
returns to Run mode and saves the current setting.
Two-Point Static TEACH (Threshold)
• Sets a single switching threshold (switching point)
• Threshold position is adjustable using “+” and “-” buttons (Manual Adjust).
• Recommended for applications where two conditions can be presented by the
user.
Two-Point TEACH is the traditional configuration method. The sensor locates a sin-
gle switchpoint at the optimal location between the two taught conditions, with the
Output ON condition on one side, and the Output OFF condition on the other.
The first condition taught is the ON condition. The Output ON and OFF conditions
can be reversed by changing Light/Dark Operate status in Setup Mode.

Two-Point TEACH and Manual Adjust
Using Manual Adjust with Two-Point TEACH moves the switching threshold position. The lighted LED on the bar graph moves to exhibit
the received signal, relative to the threshold.
Bargraph LED (Following TEACH) Relative Signal Difference/Recommendation
6 to 8 Excellent: Very stable operation.
4 to 5 Good: Minor variables will not affect sensing reliability.
2 to 3 Low: Minor sensing variables may affect sensing reliability.
1 Unreliable: Consider an alternate sensing scheme.
