Top Panel Interface
Opening the dust cover provides access to the top panel interface. The top panel interface consists of the RUN/PRG/ADJ mode
switch, LO/DO switch, +/SET/- rocker button, dual red/green digital displays, and output LED.
RUN/PRG/ADJ Mode Switch
The RUN/PRG/ADJ mode switch puts the sensor in RUN, PRG (Program), or ADJ (Adjust) mode. RUN mode allows
the sensor to operate normally and prevents unintentional programming changes via the +/SET/- button. PRG mode
allows the sensor to be programmed through the display driven programming menu (see Program Mode below).
ADJ mode allows the user to perform Expert TEACH/SET methods and Manual Adjust (see Adjust Mode below).
LO/DO Switch
The LO/DO switch is used to select Light Operate or Dark Operate mode. In Light Operate mode, the output is ON
when the sensing condition is above the threshold (for Window SET, the output is ON when the sensing condition is
inside the window). In Dark Operate mode, the output is ON when the sensing condition is below the threshold (for
Window SET, the output is ON when the sensing condition is outside the window).

+/SET/- Rocker Button
The +/SET/- rocker button is a 3-way button. The +/- positions are engaged by rocking the button left/right. The SET
position is engaged by clicking down the button while the rocker is in the middle position. All three button positions
are used during PRG mode to navigate the display driven programming menu. During ADJ mode, SET is used to
perform TEACH/SET methods and +/- are used to manually adjust the threshold(s). The rocker button is disabled
during RUN mode, except when using Window SET, see Window SET on p. 6.
Red/Green Digital Displays
During RUN and ADJ mode, the Red display shows the signal level and the Green display shows the threshold.
During PRG mode, both displays are used to navigate the display driven programming menu.
Output LED
The output LED provides a visible indication when the output is activated.

Run Mode
Run mode allows the sensor to operate normally and prevents unintentional programming changes. The +/SET/- rocker button is
disabled during RUN mode, except when using Window SET.

TEACH Procedures
The instruction manual has detailed instructions for these TEACH modes:
• Two-Point TEACH
• Dynamic TEACH
• Window SET
• Light SET
• Dark SET
• Calibration SET
Two-Point TEACH
• Establishes a single switching threshold
• Threshold can be adjusted by using the "+" and "-" rocker button (Manual Adjust)
Two-Point TEACH is used when two conditions can be presented statically to the sensor. The sensor locates a single sensing
threshold (the switch point) midway between the two taught conditions, with the Output ON condition on one side, and the Output
OFF condition on the other.

Dynamic TEACH
•
•
•
Teaches on-the-fly
Establishes a single switching threshold
Threshold can be adjusted using "+" and "-" rocker button (Manual Adjust)
Dynamic TEACH is best used when a machine or process may not be stopped for teaching. The sensor learns during actual sensing
conditions, taking multiple samples of the light and dark conditions and automatically setting the threshold at the optimum level.

• See Program Mode for programming the Offset Percent setting
A single sensing condition is presented, and the sensor positions window thresholds a programmable % offset above and below the
presented condition. In LO mode, Window SET designates a sensing window with the Output ON condition inside the window, and
the Output OFF conditions outside the window.

condition. When a condition darker than the threshold is sensed, the output either turns ON or OFF, depending on the LO/DO
setting.
