diffuse sensor with bipolar (1 PNP & 1 NPN) output. Patent pending.

This guide is designed to help you set up and install the Q3X Sensor. For complete information on programming,

performance, troubleshooting, dimensions, and accessories, please refer to the Instruction Manual at

www.bannerengineering.com. Search for p/n 181485 to view the manual. Use of this document assumes familiarity with

pertinent industry standards and practices.

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.
