Zavedení

The Sigfox network is used to transmit very short data messages and is optimized for low power consumption. It operates in the unlicensed radio band, which brings cheaper traffic, but also legislative restrictions – messages can not be sent faster than with a 10 minute interval.
Ideal applications for transmitters working in the Sigfox network are those where it is sufficient sending measured values with longer intervals (eg 1 h or longer). Conversely, inappropriate applications are those where fast system response (less than 10 minutes) is required.
The WX8xx series transmitters for the SIGFOX network are designed to measure:

• teplota
• relativní vlhkost vzduchu
• relativní vlhkost vzduchu
• CO2 concentracion in air

The transmitter performs a measurement every 1 minute. The measured values are displayed on the LCD and are sent over an adjustable time interval (10 min to 24 hour) via radio transmission in the Sigfox network to the cloud data store. Through a common web prohlížeče, cloud vám to umožňuje view both actual and historical measured values. Transmitter setup is done either by computer (locally, by communication cable) or remotely via the cloud web rozhraní.
For each measured variable, it is possible to set two alarm limits. The alarm is signalled by the symbols on the LCD display and sending an extraordinary radio message to the Sigfox network, where it is forwarded to the end user by e-mail or SMS message. Extraordinary messages can also be sent by the transmitter if the binary input state is changed (if equipped). The device is powered by an internal Li battery whose lifetime is dependent on the transmission range and operating temperature and ranges from 4 months to 7 years. The battery status information is on the display and in each sent message.
The Wx8xx series transmitters are designed with increased resistance to external influences (especially water protection), see technical data. Operation without an internal battery (with external power only) is not possible.

Bezpečnostní opatření a zakázaná manipulace

Před použitím spotřebiče si pozorně přečtěte následující bezpečnostní opatření a při používání je pamatujte!

• The device includes a radio transmitter operating in the non-license frequency band with the power specified in the Technical Parameters. This band and performance are used in the countries of the European Union. If you are in another location, make sure you can use the device before turning it on for the first time.
• Zařízení nepoužívejte na místech, kde je v letadle omezeno používání mobilních telefonů, například v blízkosti citlivých lékařských přístrojů, nebo na místech, kde dochází k odstřelům.
• Observe the authorized storage and operating conditions listed in the Technical Specifications. Take care not to subject the unit to temperatures above 60 °C. Do not expose it to direct sunlight, including solar radiation. To comply with RF exposure requirements, a minimum separation distance of 20 cm must be maintained between the user’s body and the device, including the antenna.
• Je zakázáno používat vysílač v nebezpečném prostředí, zejména v prostorách s nebezpečím výbuchu hořlavých plynů, par a prachu.

Instalace

Instalaci Installation, commissioning and maintenance must only be carried out by a qualified person in accordance with applicable regulations and standards.

Montáž zařízení
For the optimum operation of the Wx8xx Series, it is necessary to ensure their vertical position, usually by screwing them on a wall or other suitable vertical surface at the place of installation of the device. The sensor boxes are provided with 4.3 mm diameter holes for fastening with suitable screws. The holes are accessible after removing the cover. Fix the device firmly only after verifying the reception of the radio signal at the required installation location (see chapter Switching the device on).

Basic placement rules

• always install the transmitters vertically, with the antenna cover up, at least 10 cm away from all conductive objects
• do not install the devices in underground areas (the radio signal is generally unavailable here). In these cases, it is preferable to use the model with an external probe on the cable and place the device itself, for example, o patro výše.
• the devices and all cables (probes, binary inputs) should be place away from electromagnetic interference sources
• temperature and relative humidity transmitters, or their probes place so that the measured values are not affected by accidental heat sources (sunshine …) and unwanted airflow

Optimální umístění vysílače z hlediska rádiového dosahu:
All materials absorb radio waves if they must pass through them. The most significant in terms of radio wave propagation are metal objects, concrete, reinforced concrete and walls. If you install the device at a greater distance from the base station or in locations where the radio signal difficult to penetrates, observe the following recommendations:

• place the device as high as possible with the antenna better in open space than near the wall
• in rooms place the device at least 150 cm above the floor and if possible not directly on the wall. For safety reasons, you do not exceed the installation height of 2 m above the floor (the fall of the insufficiently attached device can be dangerous).
• umístěte zařízení v dostatečné vzdálenosti (alespoň 20 cm) od všech překážek, které by mohly způsobit útlum rádiových vln a alespoň 20 cm od sousedního zařízení v případě, že používáte více zařízení
• lead the cables of the external measuring probes and the external power first down to the distance of at least 40 cm from the instrument. If the cable is too long, install it by the figure.
• nepoužívejte sondy s kabelem kratším než 1 m

Exampméně optimálního a méně vhodného umístění zařízení:

Zapnutí zařízení

The device is supplied with installed battery, but in off state. The CONFIGURATION button is used to turn on the device:  off state. The CONFIGURATION button is used to turn on the device:

• models without waterproof cover (W0841E, W6810, W8810) have a CONFIGURTION button accessible via a paper clip through the hole on the top of the device
• waterproof models (W0841, W0846 and W8861) have a CONFIGURATION button under the cover. Unscrew the four screws at the corners of the box and remove the cover.
• press the CONFIGURATION button (see figures on the right) and release it as soon as the LCD lights up (through the 1 s)
• perform the installation and if necessary set up the device too (see chapter Device usage and settings)
• finally, carefully screw on the cover. For waterproof models, making sure that the gasket in the housing groove is correctly positioned.

Displej zařízení

Radio Connection Indicator – Indicates the result of checking the bi-directional radio connection with the cloud, which takes place once a day. This connection allows the transmitter to be set remotely. If the radio connection check is successful, the indicator will remain lit until the next scan. When the transmitter is switched on, the indicator lights up after 24 h (a good radio signal is required). The Radio connection indicator may light up sooner if the user deliberately selects the transmitter setting mode by pressing the CONFIGURATION button and it is correctly performed.

If the remote setting in the device is disabled, the bi-directional connection check to the cloud is not performed and the radio connection indicator remains off.
Low Battery Symbol – Illuminates if the battery is already weak and flashes when the battery is in critical condition (see the How to replace the battery chapter for details)

Information on the display – they are displayed cyclically in three steps  (the images below contain only examples of the display, the content of the display always depends on the specific model):

1. step (lasts 4 sec) the display shows data on measured quantities on channels No.1 and No.2
2. step (lasts 4 sec) the display shows data on measured quantities on channels No.3 and No.4 
3. step (lasts 2 sec.) The display shows the service information about the time of sending regular messages and external power supply 
   • P (Power) – information about presence of external power supply is refreshed with interval of 1 min.
   • 8x – shows how many times the regular message will be sent before the new transmitter setup (if this requirement is currently set in the cloud). The information is reduced with each regular report sent. Reading the new settings from the cloud occurs when the display shows “1x 0 min”. If the remote setting is in the device disabled, this value is not displayed.
   • 30 min – the time in minutes until a regular message with measured values is sent (the information decreases every minute from the currently set sending interval to 0).

Working with the cloud _____________________________

Viewnaměřených hodnot
Cloud je internetové úložiště dat. Potřebujete PC s připojením k internetu a web prohlížeč pro práci. Přejděte na cloudovou adresu, kterou používáte, a přihlaste se ke svému účtu – pokud používáte COMET Cloud od výrobce vysílače, zadejte www.cometsystem.cloud and follow the instructions in the COMET Cloud Registration Card that you received with your device.
Each transmitter is identified by its unique address (device ID) in the Sigfox network. The transmitter has an ID printed on the nameplate along with its serial number. In the list of your device in the cloud, select the device with the desired ID and and start viewnaměřených hodnot.

Checking the signal quality during device installation
The device in factory default setting will send the measured values every 10 minutes. Check in the cloud for messages to be received. Place the device temporarily to the location where it will perform the measurements and check the quality of the radio signal – in COMET Cloud click on the correct device in the My Devices list and then select Installation. If you have a problem with the signal, see the Problems with recieving radio messages chapter.

Změna nastavení zařízení na dálku
The transmitter can be set remotely from the cloud if the cloud you use supports this feature. Run the remote setting feature – in COMET Cloud click on the correct device in the My Devices list and then select Configure. Set the desired sending interval (taking into account the fact that for short sending intervals the battery life decreases), the limits, delays and hysteresis of the alarms for the individual quantities (if used), or correction of the altitude atmospheric pressure (only models with air pressure measurement). Save the new setting. The device will accept this new setting within 24 hours at the latest.
If you are running a new transmitter and want to speed up the setting, press the CONFIGURATION button (the device must be switched on beforehand) – the setting symbol (gears) lights up and the device will start  transmitting the new setting from the cloud within 10 minutes. The  transmission itself will take up to 40 minutes depending on the range of the new settings. The function can only be used once every 24 hours.
The location of the CONFIGURATION button varies depending on the transmitter model. For details, see Switching the device on chapter.

Working with the COMET Vision SW ___________________

Změna nastavení zařízení připojením k PC
Vysílač lze nastavit přímo z PC pomocí SW COMET Vision a komunikačního kabelu SP003 (volitelné příslušenství). Software COMET Vision je ke stažení na web www.cometsystem.com, jakož i návod k jeho instalaci a použití.
Unscrew the device cover and connect it to the SP003 cable with the USB port on the computer. Start the Comet Vision program and make a new device setting. After you have saved the new settings, unplug the cable and screw the device cover carefully. For waterproof devices, pay attention to the correct seal position.
Warning – do not leave the communication cable SP003 connected to the transmitter if the cable is not connected to the PC USB port at the same time or if the PC is switched off! The battery consumption in these cases increases and the battery is drained unnecessarily.

Funkce alarmu

Vysílač odesílá naměřené hodnoty v pravidelných zprávách, podle nastaveného intervalu odesílání. Kromě toho může vysílač také odesílat mimořádné poplachové zprávy, když je na sledovaném kanálu generován nový poplach nebo je zhasnutý probíhající poplach. Tato funkce umožňuje prodloužit výdrž baterie nastavením delšího intervalu odesílání pravidelných zpráv a o změnách stavu poplachu je uživatel informován mimořádnými zprávami podle aktuální situace.

Nadview vlastností vysílače pro správné nastavení funkce alarmu

• two alarms can be set for each channel (or measured quantity)
• each alarm has an adjustable limit, direction of exceeding the limit, delay and hysteresis
• alarm delay can be set to 0-1-5-30 min except CO2 channel, which has adjustable delay only to 0 or 30 min
• the longer the sending interval for regular messages, the greater the battery capacity is saved.
• after a new alarm is triggered (or an alarm is ended), an extraordinary alarm message is sent within 10 minutes at the latest. Temporary interruption of the current alarm (max. 10 min) is not indicated. See the exampna obrázcích níže.
• the content of both regular and extraordinary alarm messages is identical, both contain the measured values of all channels and current alarm states on all channels
• no even a short-term alarm (i.e. with a duration of 1 to 10 min) will not be lost – the information will be sent no later than 10 min even if the alarm is currently inactive. Device in alarm message sends the maximum value measured during the alarm duration (or the minimum value, depending on the current alarm threshold setting). See the exampna obrázcích níže.
• due to the regulation of the unlicensed radio band, the device can not send messages faster than every 10 minutes. If the device has fastest sending interval (ie 10 minutes), no extraordinary alarm messages can be sent

Vyrobené modely

COMET’s Wx8xx transmitters differ in the type of measured quantities (temperature, relative humidity, atmospheric pressure, CO2 concentracion) and the location of the sensors (compact design with internal sensors or external probes on the cable).
The enclosure covers electronic circuits, internal sensors, and a one or two batteries. Depending on the type, the devices are fitted with connectors. The antenna is protected by a cap.

W0841
Four inputs transmitter for external Pt1000 probes with Elka connector
The transmitter measures the temperature from four external probes of the Pt1000/E line (the probe is not part of the instrument). Response to the jump temperature change is usually much faster than the models from the internal sensor. The transmitter is often used to monitor locations where only a measuring probe is installed and the device itself is in a suitable location from a radio range point of view. The maximum recommended probe length is 15 m. The transmitter has increased protection against external influences (dust, water, humidity). Unused inputs of temperature probes must be fitted with supplied connector caps.

W0841E
Four inputs transmitter for external
Pt1000 probes with Cinch connector
The transmitter measures the temperature from four external probes of the Pt1000/E line (the probe is not part of the instrument). Response to the jump temperature change is usually much faster than the models from the internal sensor. The transmitter is often used to monitor locations where only a measuring probe is installed and the device itself is in a suitable location from a radio range point of view. The maximum recommended probe length is 15 m. The transmitter is equipped with an external power input.

W0846
Three inputs transmitter for external thermocouple probes and with internal temperature sensor
The transmitter measures the temperature from three external K-type thermocouple probes (NiCr-Ni) and the ambient temperature using a built-in sensor. Response to the jump temperature change is usually much faster than the Pt1000 probes. Conversely, the response of the transmitter to a step change in ambient temperature, measured by the built-in sensor, is relatively slow. Temperature probes are not part of the device. The inputs for connecting the temperature probes are not galvanically separated from each other. Make sure that the probe leads and thermocouple junction are not electrically connected to any other conductive elements. Any electrical connections between thermocouple probes can cause serious measurement errors or unstable values! For correct measurement, it is also necessary that there are no rapid temperature changes around the device. Therefore, avoid installing the device in places with warm or cold air flow (e.g. air conditioning outlet, cooling fans, etc.), or in places affected by radiant heat (near radiators, possible exposure to sunlight, etc.). The transmitter is used to monitor places where only measuring probes are introduced and the device itself is placed in a suitable place in terms of radio range. The maximum recommended length of probes is 15 m. It is recommended to use shielded cables. The transmitter has increased protection against external influences (dust, water, moisture) and is equipped with a slot for a second battery, which enables extended operation.

Způsob připojení:
Thermocouple probes must be connected with the correct polarity. Connect the probes, marked according to the ANSI standard, with the red wire to the – (minus) terminal and the yellow wire to the + (plus) terminal. Use a 2.5×0.4 mm flat screwdriver to open the terminal (see picture).

Finally, tighten the cable glands of the connected thermocouple probes to secure and seal the cables. Cables / wires with a diameter of less than 2 mm cannot be sealed in the gland. Also, do not use probes with a braided jacket (glass or metal fabric) in applications where you require the device to be waterproof. Insert attached plug into unused cable glands to seal the device.

W6810 
Compact temperature, relative humidity and CO2 concentracion transmitter
The transmitter measures the temperature, relative humidity and dew point temperature by means of internal sensors located under the cap with a stainless-steel air filter. The CO2 concentration is measured by a sensor located inside the transmitter box, which is equipped with vents at the top. The device is characterized by a simple compact design, but a relatively longer response to a step change of measured quantities than those with an external probe. The instrument is placed directly into the measured area. The transmitter is equipped with an external power input.

W8810
Compact temperature and CO2 concentracion transmitter
The transmitter measures the temperature and the CO2 concentration by a sensors located inside the transmitter box, which is equipped with vents at the top. The device is characterized by a simple compact design, but a relatively longer response to a step change of measured quantities than those with an external probe. The instrument is placed directly into the measured area. The transmitter is equipped with an external power input and an slot for 2nd battery, allowing for extended battery operation.

W8861
Transmitter with input for external probe measuring CO2 concentration, with internal temperature and atmospheric pressure sensors
The transmitter measures temperature and atmospheric pressure from built-in internal sensors and CO2 concentration from an external probe of the CO2Rx/E series (not included). The transmitter allows to measure higher CO2 concentrations (depending on the used probe) and with faster response compared to devices with internal CO2 sensor. Conversely, the response of the sensor to a step change in temperature is relatively slow. The CO2Rx/E probes provide calibrated readings and are therefore interchangeable without interfering with instrument settings. The maximum recommended probe length is 4 m. The transmitter has increased protection against external influences (dust, water, humidity) and is equipped with an slot for 2nd battery, allowing for extended battery operation.

Poznámky k aplikaci

Operation of transmitter in various applications ___________
Před uvedením do provozu je nutné nejprve posoudit, zda je jeho použití vhodné pro daný účel, určit jeho optimální nastavení a v případě, že je součástí většího měřicího systému, připravit metrologickou a funkční kontrolu.

• Inappropriate and risky applications: The transmitter is not intended for applications where the failure of its operation could directly endanger the lives and health of persons and animals or the function of other devices that support life functions. For applications where failure or malfunction could result in serious property damage, it is recommended that the system be supplemented by a suitable independent signalling device that evaluates this status and, in the event of a malfunction, prevents the damage (see chapter Safety precautions and forbidden handling).
• Umístění zařízení: Follow the guidelines and procedures in this manual. If possible, select the location for the device where it is minimally affected by external environmental influences. If you perform measurements in fridges, metal boxes, chambers, etc., place the device outside the exposed area and insert external probe(-s) only.
• Location of temperature sensors: Place them in places where there is sufficient airflow and where you anticipate the most critical location (according to application requirements). The probe must be sufficiently inserted or otherwise sufficiently connected to the measured area to prevent any influence of the measured values by the undesirable heat supply on the wires. If you monitor the temperature in the air-conditioned store, do not place the sensor in the air conditioner direct flow. E.g. in large chamber refrigerators, the distribution of the temperature field can be very inhomogeneous, deviations may reach up to 10 ° C. You will also find the same deviations in the deep-freeze box (e.g. for blood freezing, etc.).
• Umístění čidel vlhkosti závisí opět na požadavcích aplikace. Je velmi problematické měřit vlhkost v lednicích bez stabilizace vlhkosti. Zapnutí/vypnutí chlazení může způsobit výrazné změny vlhkosti v rozsahu desítek procent, i když je střední hodnota vlhkosti správná. Běžná je kondenzace vlhkosti na stěnách komor.

Measurement of calculated humidity variables _____________
Přístroj z vypočtených proměnných vlhkosti poskytuje pouze teplotu rosného bodu. Další vypočtené veličiny vlhkosti lze získat na úrovni dalšího zpracování dat v SW.

Měření atmosférického tlaku

Models with atmospheric pressure measurement allow display on sea level pressure readings. In order for the conversion to be correct, you must, during device configure, enter the altitude at which the device will be located. Altitude can be entered either directly, in the form of altitude data, or indirectly, as an offset of absolute pressure. Offset of pressure is the subtraction of pressure required (ie converted to sea level) minus absolute pressure.
When converting pressure to sea level, the device takes into account the temperature of the air column at the point of air pressure measurement. Therefore, it is necessary to place the device with the altitude correction in the outdoor. If this device is placed in a heated room, the error in the recalculated pressure measurement will increase with the temperature difference between the device and the outdoor air increases.

Problems with measurement accuracy __________________
Incorrect measured values of temperature and relative humidity are most often caused by inadequate probe position or measurement methodology. Some notes on this issue are listed in the chapter Operation of transmitter in various applications.
Another group of problems are random peaks in the measured values. Their most common cause is the source of electromagnetic interference near the instrument or cables. In addition, it is also necessary to focus on whether cable insulation is damaged in any place and that there are no accidental connections of conductors with other metal parts.

Problems with recieving radio messages ________________
Příčin problémů může být mnoho. Pokud příjem rádiových zpráv vůbec nefunguje, můžete zkusit následující kroky:

• check whether the display is on and that the battery is weak
• verify that the set transmission interval matches your expectations (on the bottom line of the display, with of the 10 seconds interval always for 2 seconds shows the number of minutes left until the message is sent)
• verify the coverage of the SIGFOX network for the transmitter (https://www.sigfox.com/en/coverage or more detailed http://coverage.simplecell.eu/)
• transmitting from the interior of some buildings can be difficult, from basements, as a rule, impossible. For testing purposes, therefore, position the device as high as possible above the floor, put it on the window, or even on the outside window sill (secure the device against falling). If possible, test the location of the transmitter in other parts of the building with respect to the world’s sides.

Doporučení pro provoz a údržbu

Recommendations for metrological control _______________
Metrologické ověřování se provádí dle požadavků vlastní aplikace v uživatelsky definovaných termínech. V některých případech musí kalibraci provést nezávislá státem akreditovaná laboratoř.

Recommendations for regular checks ___________________
Výrobce doporučuje v pravidelných intervalech kontrolovat systém, ve kterém je zařízení začleněno. Rozsah a rozsah prohlídky závisí na aplikaci a vnitřních předpisech uživatele. Doporučuje se provést tyto kontroly:

• metrological verification
• regular checks at intervals as specified by the user
• evaluation of all the problems that have occurred since the last inspection
• visual inspection of the device, check the condition of connectors and cables, and cover integrity

How to replace the battery ____________________________

Výměnu baterie smí provádět pouze osoba, která zná zásady bezpečného zacházení s lithiovými primárními bateriemi. Nevhazujte je do ohně, nevystavujte je vysokým teplotám a mechanicky je nepoškozujte. Použité baterie likvidujte s nebezpečným odpadem.
Pokud se zobrazí symbol slabé baterie starts to appear in the COMET cloud received messages during operation, it is advisable to replace the transmitter battery in the next 2-3 weeks. The empty battery symbol also appears on the device display. A low battery indication may also occur if the device is operated at extremely low temperatures even when the battery is still usable (usually outdoors when in out-of-night messages). During the day (after temperature rise), the indication disappears. In this case, it is not necessary to change the battery.
Kriticky slabá baterie, která může kdykoli selhat, je označena prázdným symbolem baterie v cloudu COMET a blikající symbol prázdné baterie na displeji zařízení. Vyměňte baterii co nejdříve.

Poznámka: When operating the transmitter at very low temperatures, the flashing of the blank battery symbol may not be on the sensor display visible.

To replace the battery, unscrew the device cover, remove the old battery and insert the new battery with the correct polarity. Refer to the battery symbol + (plus pole) printed on the electronics board at the battery location:

For models with two battery slots: 1 or 2 batteries can be fitted. If you decide to use two batteries, always use pieces of the same type and manufacturer, from one supply, ie. of the same age. Always use new, unused batteries. It is forbidden to mix batteries of different manufacturers or to mix new batteries with used ones. If you use only one battery, you can fit it into any slot.
Check the seal integrity in the housing (if equipped) and reinstall the cover. Batteries can be purchased under their designation (SL2770/S) or, if purchased from the manufacturer (COMET SYSTEM, s.r.o.), under order code A4206.
