WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to
serious injury or death. This device does not include the self-checking redundant circuitry necessary
to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.

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,
indicates that a target is present at a distance beyond
the background suppression distance and is being suppressed. In Light Operate mode, the output switches off when
displays. 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.
