Fine-Detection Programming
Fine-Detection programming teaches the QL50 Sensor to respond to a more precise
specific luminescence intensity and ignore surfaces with either less intense or more
intense luminescence. Fine-Detection programming compares target luminescence to
background luminescence and automatically selects light operate or dark operate.
Light Operate: detects a target that is more luminescent than the background.
Sensing the more luminescent target will close the normally-open output, turn on the
yellow LED, and cause the output to conduct current (see Figure 3).
Dark Operate: detects a target that is less luminescent than the background.
Sensing the less luminescent target will close the normally-open output, turn on the
yellow LED, and cause the output to conduct current (see Figure 3).

*Sensor has a 35-second time-out. If a 35-second interval elapses between steps, the sensor returns to RUN mode without saving new values.
**Green LED brightness may diminish during poor signal conditions (near transition areas).
