6 - EN Wireless Sensor RT2eEL6107EGeneral application and safety information2. General application and safety information2.1 Antenna positionRange approx. 1000mThe range (always dependent upon the structural conditions of the building such as cement ceilings, water pipes etc.) is approx. 100m in a typical office environment  5.1 Radio settings.In which direction shouldthe antenna point?With this type of antenna, the signal is emitted at right angles from the antenna. The direction can be visualized as being like a CD that is skewered on the antenna. This makes it clear that it is best for the antenna to be placed vertically, pointing upward, so that it transmits to all rooms on the same floor. If the antenna is placed horizontally, reception is best on the floors above and below.Metal objects such as shelves, reinforced concrete walls, ventilation and energy shafts, but also the opening of a refrigerator door can lead to the weakening of the signal. This kind of effect is usually very much limited to the location.Moving the wireless sensor within an area of 2.5 meters (sometimes just a few centimeters) is usually adequate to completely change the reception (  3.1.1 Transmitted frequency & radio channel). Move the wireless sensor forward, backward, up and down within this area. The wireless sensor should always be mounted at least 1.5m above the ground.If no direct line of sight to the wireless sensor is available, the angular position (angle in relation to the horizontal axis and rotation of direction) can improve reception.Placing the wireless sensors in an open stairwell is an additional possibility to avoid one or more reinforced steel ceilings that are an obstacle.For additional details regarding the antennas  5.1 Radio settings2.2 Temperature effect- For the range of application,5. Technical data.- It can't be guaranteed that the loggers will function properly if the datalogger is exposed to temperatures which exceed the specified threshold range. Experience shows that at storage temperatures below -50°C, the battery freezes, measurements are no longer taken and setpoint tracking may be temporarily interrupted. Once it has been returned to room temperature, the logger must be reprogrammed before it can be used again.- At temperatures below - 20°C, the display is not easily readable; however, longterm use is not affected.- For longterm use above 40°C, lithium battery passivation can lead to temporary reading problems (self-discharge protection), which can be resolved with repeated utilization.- At temperatures above 45°C, battery self-discharging increases. With long term use above 45°C, the battery lifetime can be reduced by about 1/3. - Exposure to temperatures above 55°C can result in permanent discoloration of the display.- There is danger of a gas explosion if the lithium battery is heated to temperatures exceeding 100°C.2.3 Exceptional environmental conditionsPay attention to the following when using the wireless sensor in exceptional environmental conditions:- IR radiation (heat) and superheated steam can damage the surface coating of the casing- There is a risk that the battery may explode if the logger is used under microwave radiationInitial startupTHE WIRELESS SENSOR MUST BE AT ROOM TEMPERATURE BEFORE INITIAL STARTUP!

This is a type of frequency shift keying modulation that uses a Gaussian filter to smooth positive/negative frequency deviations:- FCC compatible- Address match for detection of incoming package - Automatic retransmission of data packages - Automatic CRC and preamble generation- Build in test function for the radio signal- Use of frequency hopping in the 915MHz band- Limited number of sensors and transmitters used- Installation requirementsRisk assessment for Receivers and TransmittersThe Elpro wireless system is made up of a receiver and a transmitter function in the wireless datalogger and in each radio sensor. The receivers are divided into three classes, each having its own set of minimum performance criteria. The classification is based upon the impact the equipment has on persons in case of a failure.The Elpro radio sensor system complies to a class 2 system:A failure causes loss of function but not physical risk of a person
EN - 17Wireless Sensor RT2eEL6107EApprovalsITESENENFRITES6.3 FCCIn the USA, the FCC (Federal Communications Commission) regulates the use of frequencies for RFequipment. CFR 47 part 15 (Code of Federal Regulations) covers the unlicensed ISM bands. This is usually referred to as FCC part 15. All equipment must be certified with the FCC with the issuance of a Grant of Authorization by the FCC. When the product is approved, the FCC issues an identification number which the product must be marked with.The part 15 sections for ISM band radios are:- 15.19 / RSS-210: Manual requirements- 15.35: General rules for certification measurements- 15.105: Manual requirements- 15.109: Radiated emission limits for unintentional radiators- 15.205: Restricted bands of operation- 15.209: Radiation limits for intentional radiators- 15.247: Frequency Hopping and Spread Spectrum (FHSS), operation within the bands 902 - 928MHz, 2400 - 2483.5 MHzSpurious emissions and restricted bandsA large part of the FCC Part 15 is about the limit of spurious emissions (harmonic component) andrestricted bands. The main concept behind part 15 is that a general set of rules must be followed, but with exceptions for different application and frequency bands.Emissions are divided into two parts:- Unintended radiators, like receivers and transmitters in standby or other radiators requirements are given in 15.109- Intended radiators, like active transmitters requirements are given in 15.209There are a number of restricted frequencies according to 15.205 which cannot be used for active transmissions, but spurious emissions can be produced. The levels are given in EIRP, Electrical Field Strength Power, at a distance of 3 metersWhite Paper915MHz bandSection 15.249 gives the opportunity to use the 902-928MHz band with an output power of 50mV/m at 3 meters or -1.2dBm. The harmonics are limited to 500uV/m or -41.2dBm. This band is commonly referred to as the 915MHz band in the USA. There are no restrictions on duty cycle or the application.Even higher output power can be used according to section 15.247. This implies the use of frequency hopping. The following requirements must be fulfilled for the use of the 902-928MHz band under section 15.247:- Hopping channels shall be separated by minimum 25 kHz or the 20dB bandwidth of the hopping channel, whichever is greater.- The system shall hop to channel frequencies that are selected at the system hopping rate from a pseudorandomly ordered list of hopping frequencies.- If the 20 dB bandwidth of the hopping channel is less than 250 kHz, the system shall use at least 50 hopping frequencies and the average time of occupancy on any frequency shall not be greater than 0.4 seconds within a 20 second period.- If the 20 dB bandwidth of the hopping channel is 250 kHz or greater, the system shall use at least 25 hopping frequencies and the average time of occupancy on any frequency shall not be greater than 0.4 seconds within a 10 second period.- The maximum allowed 20 dB bandwidth of the hopping channel is 500 kHz.- Maximum peak conducted output power is 1W in the 902-928MHz band if more than 50 hopping channels are used. The limit is 0.125W for 25 to 50 hopping channels.Frequency Electrical Field Strength EIRP216-960MHz 200mV/m -49.2dBm
