Original Document 134420 Rev. D 27 March 2017 134420 MINI-BEAM (Low Power Model) Efficient power management technology enables the FlexPower battery system to briefly step up the switched power voltage to activate the low-power MINI-BEAM[®] sensor, which is optimized for low duty cycle pulse operation. Once activated, the input reads the sensor then the switched power shuts off to prolong battery life, operating the MINI-BEAM in short pulses rather than continuously. ## **Sensor Mounting and Alignment** MINI-BEAM sensors perform most reliably when they are properly aligned and securely mounted. For maximum mechanical stability, mount MINI-BEAM sensors through 18 mm diameter holes by their threaded barrel where available or use a mounting bracket. Begin with line-of-sight positioning of the MINI-BEAM sensor to its target. When using a retroreflective sensor, the target is the retroreflector (retro target). For diffuse or convergent sensing modes, the target is the object to be detected. Apply power to the sensor. Advance the 15-turn gain control to maximum (clockwise end of rotation), using a small flat-bladed screwdriver. The gain control is clutched at both ends to avoid damage and “free-wheels” when either endpoint is reached. Because the low-power MINI-BEAM operates in pulses instead of continuously, sensor alignment is more complicated. To simplify alignment, force the sensor to mimic continuous operation by hooking up the sensor to a fixed 5.0 voltage supply or by configuring the warm-up time to its maximum allowable value. After establishing the optimum position, configure the warm-up time back to the value listed in the specifications table. When the MINI-BEAM sensor receives its light signal, the red LED alignment indictor turns ON and flashes at a rate proportional to the signal strength. Move the sensor to find the center of the movement zone within which the LED indicator remains ON. Reducing the gain setting reduces the size of the movement zone and permits more precise alignment. Repeat the alignment motions after each gain reduction. When optimum alignment is achieved, mount the sensor and any applicable target (retroreflective) in that position. Increase the gain to maximum. Test the sensor by placing the object to be detected in the sensing position, then removing it. The alignment indictor LED should come ON when the sensing beam is established (light condition), and go OFF when the beam is broken (dark condition). If the alignment indicator LED stays ON for both sensing conditions, consider the following tips for each sensing mode. ## **Diffuse-Mode Alignment** ## Light condition: object in beam Dark condition: no object in beam If the alignment LED does not go off when the object is removed from the beam, the sensor is probably detecting light reflected from a background object. To improve performance: - Reduce the reflectivity of the background by painting the surface flat black, scuffing any shiny surface, or drilling a large hole directly opposite the diffuse sensor. **==> picture [12 x 10] intentionally omitted <==** **----- Start of picture text -----**
Object
**----- End of picture text -----**
- Move the sensor closer to the object to be detected and reduce the gain adjustment. Rule of thumb for diffuse sensing: the distance to the nearest background object should be at least three times the sensing distance. ## **Retroreflective Mode Alignment** Light condition: no object in beam Dark condition: object in beam A highly reflective object may reflect enough light back to a retroreflective sensor to allow the object to cross the beam without being detected, a situation called proxing. Use the following methods to reduce this effect: - Position the sensor and retro target until the beam does not strike a shiny surface perpendicular to the sensor lens. **==> picture [11 x 14] intentionally omitted <==** **----- Start of picture text -----**

Sample and Report Rates
DX81 Battery Life (Years)
**----- End of picture text -----**
For each sensor characterized, a boost voltage and warmup time was specified. The sample and reports rates were varied to calculate the estimated battery life. For example, a Banner Optical sensor, model SM312DQD-78419, set to a boost voltage of 5 volts, a warm-up time of 4 milliseconds, and a sample and report rate of 16 seconds, should have a battery life of just over 6 years. The curves for discrete devices represent a “worst case” as far as battery use because we are assuming for each sample of the sensor’s output a change in state has occurred (e.g., target present to target absent or vice versa), sending a radio message from Node to Gateway. No messaging occurs unless there is a change to report. Actual battery life depends on how many state changes actually occur. All battery life calculations are approximations based on a strong radio signal. Weaker radio connections and missed packets will decrease the battery life. ## **Low-Power MINI-BEAM Specifications** |**Supply Voltage**|**Adjustments**| |---|---| |5 V dc
