Dynamic TEACH Programming Using the Remote TEACH Line
To pulse the TEACH line, momentarily connect the Remote (gray) wire to dc common; no
press-and-hold procedure is required to enter TEACH mode. (This is the equivalent of a
“click” when using the sensor TEACH push button.)
1. Using the Static TEACH procedure, set up the application’s Output ON and OFF
conditions. (This step is not necessary if the Output ON and OFF conditions already
are configured properly for your application.)
2. Double-pulse the Remote TEACH line (see Figure 3). The sensor is now ready for
Dynamic TEACH. The bi-color (green/red) indicator will be ON solid red and the
yellow indicator will flash.
3. Hold the Remote line low. Sample sensing events while continuing to hold the
Remote line low.
4. Release the Remote line when event sampling is complete. The green indicator will
turn ON and the sensor will return to RUN mode with the new settings, if the
contrast is adequate.
If the contrast is not adequate, the red indicator will flash at a rate proportional to the
received light signal strength and the yellow indicator will be ON solid, indicating that the
sensor needs to be retaught. In this case, return to step 2.
NOTE: To exit Dynamic TEACH without updating, wait 90 seconds or cycle sensor power.
Troubleshooting
The SLE10 Expert’s Power LED may begin to alternate flashing red/green; this
indicates a microprocessor memory error. If it occurs, try reteaching the sensor, or
try cycling power ON and OFF, then reteaching the sensor. If this does not solve the
problem, or if it occurs frequently, replace the sensor.
