Active TEACH Indicators• DYN = Dynamic TEACH selected (Amber)• WND = Symmetric window thresholds areactive (Amber)In Run mode, the 3-digit, 7-segment display provides real time information about signal strength for all models and targetposition for models with a fixed background suppression distance. The numeric value of 0 to 990 represent the amount ofthe received light divided by the threshold, and represents the excess gain of the sensing event expressed as a percentageof the switch point. This value is called normalized signal strength (NSS). A NSS display range of 999 indicates a saturatedreceived light signal, meaning that low contrast detection is not possible.In single threshold teach modes (Two-Point Static, Dynamic, Light Set, or Dark Set), the output switches at a displayedvalue of 100 (excess gain of 1.0).For models with a specified background suppression distance, indicates that a target is present at a distance beyondthe background suppression distance and is being suppressed. In Light Operate mode, the output switches off whendisplays. For the LD50 models, the sensor's output state when displaying can be controlled using the menu.By default, the sensor treats a target in the background as a dark signal and honors the LO/DO selection.A displayed value of indicates no light received or a loss of signal.In Window Set teach mode, the value 100 represents the taught signal strength. The displayed value is the percentage ofthe received light divided by the taught signal strength. The output switches at displayed values above and below 100 asdetermined by the user-selected window offset percentage.Output Indicator• On—Outputs conducting (closed)• Off—Outputs not conducting (open)Stability Indicator (STB)• On—Stable light signal received• Flashing—Light intensity is within the switching threshold hysteresis band• Off—No light signal receivedActive TEACH Indicators (DYN and WND)• DYN and WND off—Two-Point Static , Light Set, or Dark Set TEACH mode selected (Two-Point Static TEACH is thedefault).• DYN and/or WND flashing—The sensor is in TEACH mode.• DYN on—Dynamic TEACH mode selectedQ3X Laser Contrast Sensor4 www.bannerengineering.com - Tel: 763.544.3164
