Sensor Programming
Programming Procedures: Two push buttons, Dynamic (+) and Static (-), may be used to access and set programming parameters. For
remote programming, connect a switch or digital input to the gray wire; length of the individual pulses is equal to the value T:
0.04 seconds ≤ T ≤ 0.8 seconds
Returning to RUN mode: TEACH and SETUP modes each may be exited in one of two ways: by exercising the 60-second time-out, or
by cancelling out of the process. In TEACH mode, the sensor will return to RUN mode without saving any of the new settings; in SETUP
mode, the sensor will return to RUN mode but save all of the settings. To cancel out of TEACH mode, press and hold the Static (-) button
for 2 seconds; to cancel out of SETUP mode, press and hold both the Static (-) and Dynamic (+) buttons for 2 seconds.
Output 2: The setpoint(s) for each output can be set independently of one another. However, the functional range available for output 2
is dictated by the automatic power and gain settings established for output 1. Whenever output 1 is taught, output 2 also must be re-
taught. Applications hint: teach the weakest signal on output 1 first. Output 1 sets the emitter power. If only output 2 will be used, output 1
must be taught first. Or, enable tracking and teach only output 1, and then output 2 will be the same as output 1.
Dynamic TEACH and Adaptive Thresholds: Dynamic TEACH is used to program sensitivity during actual machine run conditions. Dur-
ing Dynamic TEACH, the sensor takes multiple samples of the light and dark conditions and automatically sets the sensitivity at the
optimum level. For the discrete output, Dynamic TEACH activates the sensor’s adaptive threshold system, which continuously tracks
minimum and maximum signal levels, and automatically maintains centering of the switch point between the light and dark conditions.
The adaptive threshold system remains in effect during RUN mode to automatically adjust for changes in the light or the dark conditions.
When Dynamic TEACH mode is used to program sensitivity, the output ON state (light or dark operate) will remain as it was last pro-
grammed. To change to either light or dark operate, use the SETUP mode (see
Sensitivity may be adjusted at any time when the sensor is in RUN mode by clicking the “+” and “-” buttons. However, when a manual
adjustment is made, the adaptive threshold system is disabled (cancelled).
Analog Outputs
Output 1 is configured for either 4 to 20 mA or 0 to 10V dc analog output, depending on the model. The sensor may be programmed
using the two-point TEACH (either static or dynamic) or single-point window SET.
Two-point static or dynamic TEACH: The sensor sets the first taught condition to the highest output level (either 20 mA or 10V), and
the second taught condition to the lowest level (either 4 mA or 0V), and scales between these points. If the first condition taught has more
returned light, the sensor will be in Light Operate mode (LO). If the first taught condition is darker, the sensor will be in Dark Operate
mode (DO). To change the slope of the analog output (refer to
Figure 2. Analog output as a function of target position – two-point static or
on page 4), toggle LO/DO in
Single-point window SET: The sensor sets the taught condition to the mid-point of its range (12 mA or 5V, depending on the model).
For Light Operate mode, the sensor will automatically scale up to 20 mA (or 10V) for maximum light condition (the maximum possible
received signal) and down to 4 mA (or 0V) for maximum dark condition (no signal), and vice-versa for Dark Operate mode. To change the
slope of the analog output (refer to
Figure 3. Analog output as a function of target position – window SET
on page 4), toggle LO/DO in
on page 12.
An OFF-delay enabled for the analog output acts as an averaging function. During the OFF-delay period, the sensor will take multiple
analog readings and average the result before changing the analog value. This acts to reduce the effects of major spikes in the analog
system, in effect “smoothing” the output reading.
