2 WORLD BEAM QS0HO Series Water Sensor Overview he Banner QS0HO series water sensor was developed to detect the presence of water. Its electro-optical components are tuned to one absorption band of water in the long infrared spectrum. he emitted infrared light penetrates many types of plastic and glass containers, but will not pass through water-based fluids, nor through opaque substances such as wood, metal or cardboard. Accessory apertures are available to attenuate or shape the beam for low-gain applications, for example, clear water in a clear bottle. Low-gain models are recommended for sensing applications where the liquid container is transparent or when the thickness of liquid being detected is small. Some examples are clear glass test tubes and clear PE beverage bottles. High-gain models are recommended when the liquid container is light-blocking (translucent) and when the thickness of liquid being detected is large. Some examples are HDPE milk containers, colored PE beverage bottles, and etched glass containers. For all applications, the sensors must be installed to maximize the optical contrast between the clear and blocked states. he installer can use apertures and mechanical alignment of the sensors to achieve the best results (see page ). he QS0HO sensor enhances the available contrast by taking advantage of the absorption band of water. For advanced applications, a 00V analog output is available. he analog output allows the user to directly measure the amount of signal attenuation. he analog output value can be filtered and a switching threshold determined in a PLC or computer as required for the application. Please consult the factory for more information on using the analog output. Each discrete output model has two bipolar outputs that switch simultaneously: one each NPN (sinking) and PNP (sourcing). Light Operate and Dark Operate models are available. he versatile housing provides multiple mounting configurations in a minimum of space. hese sensors are extremely rugged, powerful and leakproof, with epoxy-encapsulated electronics for maximum resistance to mechanical shock and vibration. hey are powerful enough to burn through dust and many types of industrial and process contamination. he sensors innovative circuitry provides excellent EMI/RFI noise immunity. For applications where optical crosstalk between multiple sensor pairs may be a problem, either of two modulation frequencies may be selected. (Set each emitter to the same frequency as its receiver, via the sensor hookup; see configuration on page or hookups on page 6.) Indicators Each sensor has a green Power ON/OFF indicator, visible from 60 (see Figure ). Receivers also have a yellow AID indicator that flashes to show signal strength. (he higher the flash rate, the more light is received; a solid AID LED indicates excellent signal.) Discrete models also have a large yellow LED that lights when an output is conducting. Receiver Output Conducting (Yellow, Discrete Models Only) Figure. Features Power (Green) Emitter Power (Green) AID Indicator (Yellow) Sensor Configuration eaching Limits Discrete models require no configuration; simply align the emitter to the receiver to maximize contrast between the clear and blocked conditions (see procedure on page ). For analog models in high-contrast applications, alignment may be the only configuration needed. For more challenging applications using analog models, use the EACH procedure to maximize contrast. his procedure is accomplished by pulsing the receiver s white wire (see hookups on page 6 and procedure on page ). Analog output slope also can be inverted from positive to negative or back again. P/N 666 rev. A el: 76..6

3 WORLD BEAM QS0HO Series Water Sensor Sensor Alignment When Empty Container Can Be Presented. Position both the emitter and the receiver loosely in their mounting position. See Figure.. Present the clear condition for the application (an empty container).. Verify that both emitter and receiver are wired for the same modulation frequency (see below).. Adjust the emitter first, then the receiver. Adjust the emitter s position until the receiver AID indicator is ON steady, or is flashing at its fastest rate.. ighten the emitter mounting hardware, then repeat step for the receiver. 6. Block the sensor beam with the target and verify that the output changes state. Sensor Alignment When Empty Container Cannot Be Presented For this procedure, the clear condition is no container at all.. Mount loosely and mechanically align the emitter and the receiver such that their faces are parallel to one another. (he AID indicator should be ON steady.). Rotate the emitter in one direction until the receiver AID indicator begins to flash. Repeat in the other direction. Position the emitter midway between those two positions and tighten the emitter mounting hardware.. Repeat step for the receiver.. Block the sensor beam with the target and verify that the output changes state. ion he modulation frequency (A or B) is selected by the state of the gray wire (on cabled models; pin on QD models see hookups, page ). A voltage or no connection selects frequency A; connecting it to selects frequency B. Each emitter must be set to the same frequency as its receiver. Emitter Inhibit o disable (or inhibit) the emitter LED (useful for testing the receiver operation), connect the white wire to voltage. Figure. Sensor alignment procedure el: P/N 666 rev. A

Restore Factory EACH: Reverts the sensing limits to the factory default limits (max contrast); output slope is not affected. Analog Output Slope: oggles the analog output to send a high signal when object is absent (positive slope) or present (negative slope).
