Sensor Programming
Three TEACH methods may be used to program the sensor:
• Teach individual minimum and maximum limits,
• Use the Auto-Window feature to center a sensing window around the taught position, or
• Simultaneously use Auto-Window and position a threshold for background suppression at the taught position.
The sensor may be programmed either via its two push buttons, or via a remote switch. Remote programming also may be
used to disable the push buttons, preventing unauthorized personnel from adjusting the programming settings. To access
this feature, connect the gray wire of the sensor to 0–2 V dc, with a remote programming switch between the sensor and
the voltage.
NOTE: The impedance of the Remote Teach input is 12 kΩ.
Programming is accomplished by following the sequence of input pulses. The duration of each pulse (corresponding to a
push button “click”), and the period between multiple pulses, are defined as 0.04 seconds < T < 0.8 seconds

Figure 4. Teaching independent minimum and maximum limits
The outputs are independent. To readjust minimum or
maximum limits for either output, follow the teach
procedure for that output only.
Repeat the teach procedure for the other output, if used.
Push Button Method
1. Enter Programming Mode
Action Result
Push and hold the Output 1 button for output 1 or the Output 2
button for output 2 The corresponding output LED turns solid Red and the sensor waits
for first limit.
2. Teaching the First Limit
Action Result
Position the target for the first limit
Click the same button (Output 1 button for output 1; Output 2
button for output 2) Sensor learns the first limit position and the LED for the selected
output changes to flashing red
3. Teaching the Second Limit
