Wavetronix SmartSensor Advance Manual page 10

The CTAD shall be capable of continuous operation over an ambient temperature range of -40°F to 165°F (-40°C to 74°C).
The CTAD shall be capable of continuous operation over a relative humidity range of 5% to 95% (non-condensing).
Dry snow and moist snow are terms defined by the International Hydrological Program of the United Nations in the publication "The Internation-
al Classification For Seasonal Snow on the Ground." Dry snow has a water volume content of 0% and moist snow has water content of less than
3%. Wet snow has higher fractional volumes of water and varying fractional volumes of air. Depending on the precipitation rate and the fraction-
al volumes of ice, air, and water, the CTAD shall be capable of continuous operation in wet snowfall. For example, with typical fractional volumes
of ice, air, and water the CTAD shall be capable of continuous operation in wet snowfall with a precipitation rate less than 1 in. per hour (2.5 cm)
per hour. Furthermore, as instructed in the user documentation, the sensor should be installed with a down tilt for accurate detection. A down tilt
alignment will also help shield the sensor front and minimize the possibility of dry, moist, and wet snow buildup in extreme weather conditions.
12.0 Testing.
12.1 FCC. Each CTAD shall be Federal Communications Commission (FCC) certified under CFR 47, part 15, section 15.245 or 15.249 as
an intentional radiator.
The FCC certification shall be displayed on an external label on each CTAD according to the rules set forth by the FCC.
The CTAD shall comply with FCC regulations under all specified operating conditions and over the expected life of the CTAD.
The CTAD shall be tested under IEC 61000-4-5 class 4 (lightning surge protection).
12.2 NEMA TS 2-1998 testing. The CTAD shall comply with the applicable standards stated in the NEMA TS 2-1998 Standard. Third
party test results shall be made available for each of the following tests:
• Shock pulses of 10 g, 11 ms half sine wave
• Vibration of 0.5 g up to 30 Hz
• 300 V positive/negative pulses applied at one pulse per second at minimum and maximum DC supply voltage
• Cold temperature storage at -49°F (-45°C) for 24 hours
• High temperature storage at 185°F (85°C) for 24 hours
• Low temp, low DC supply voltage at -29.2°F (-34°C) and 10.8 VDC
• Low temp, high DC supply voltage at -29.2°F (-34°C) and 26.5 VDC
• High temp, high DC supply voltage at 165.2°F (74°C) and 26.5 VDC
• High temp, low DC supply voltage at 165.2°F (74°C) and 10.8 VDC
13.0 Manufacturing. The CTAD shall be manufactured and assembled in the USA.
The internal electronics of the CTAD shall utilize automation for surface mount and wave solder assembly, and shall comply with the re-
quirements set forth in IPC-A-610C Class 2, Acceptability of Electronic Assemblies.
The CTAD shall undergo a rigorous sequence of operational testing to ensure product functionality and reliability. Testing shall include the
following:
• Functionality testing of all internal sub-assemblies
• Unit level burn-in testing of 48 hours' duration or greater
• Final unit functionality testing prior to shipment
Test results and all associated data for the above testing shall be provided for each purchased CTAD by serial number, upon request.
14.0 Support. The CTAD manufacturer shall provide both training and technical support services.
14.1 Training. The manufacturer-provided training shall be sufficient to fully train installers and operators in the installation, auto-config-
uration, and use of the CTAD to ensure accurate CTAD performance.
The manufacturer-provided training shall consist of comprehensive classroom labs and hands-on, in-the-field, installation and configu-
ration training.
