 Display and Indicators The display is a 4-digit, 7-segment LED. The main screen is the Run mode screen. For 2-pt, BGS, FGS, and DYN TEACH modes, the display shows the current distance to the target in millimeters. For dual TEACH mode, the display shows the percentage matched to the taught reference surface. A display value of indicates the sensor has not been taught.
 
 Output Indicator
 • On—Outputs conducting (closed)
 • Off—Outputs not conducting (open)
 Stability Indicator (STB)
 • On—Stable signal within the specified sensing range
 • Flashing—Marginal signal, the target is outside the limits of the specified sensing range, or a multiple peak condition exists
 • Off—No target detected within the specified sensing range
