Q3X Laser Contrast Sensor
1.3.1 Display and Indicators
Figure 2. Display in Run Mode
In Run mode, the 3-digit, 7-segment display provides real time information about signal strength for all models and target position for
models with a fixed background suppression distance. The numeric value of 0 to 990 represent the amount of the received light divided
by the threshold, and represents the excess gain of the sensing event expressed as a percentage of the switch point. This value is called
normalized signal strength (NSS). A NSS display range of 999 indicates a saturated received 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 displayed value of 100
(excess gain of 1.0).
For models with a specified background suppression distance,
background suppression distance and is being suppressed. In Light Operate mode, the output switches off when
background suppression models, the sensor's output state when displaying
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 of the received
light divided by the taught signal strength. The output switches at displayed values above and below 100 as determined 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 received
Active 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 the default).
•
DYN and/or WND flashing—The sensor is in TEACH mode.
•
DYN on—Dynamic TEACH mode selected
•
WND on—Symmetric Window thresholds are active. The switch points are above and below 100 by the offset percentage
