93 Prepare Probe3.1 Insert batteryFor the energy supply of the probe, a lithium battery 3.6V, 2.1Ah is provided as a stan-dard. The service expectancy of the battery depends on the transmission interval andthe ambient temperature and will be approx. one year for the settings made in the fac-tory (transmission interval 10 sec and room temperature). Figure 3: Insert batteryStep What to do: 1 Screw open the handle counter-clockwise and withdraw one half of the handle. 2 Pull out the circuit board from the handle by approx. 25 mm. 3 Loosen the screwed clamps of the minus pole and the plus pole by means of a screw driver.4 Insert the plus pole of the battery into the screwed clamp indicated by (+). Tilt the battery and insert its minus pole into the screwed clamp indicated by (-). 5 Re-fasten the screwed clamps of the minus and plus poles by means of a screw driver. 6 Slide the circuit board back into the handle to the stop. 7 Screw together the handle and the half of the handle in clockwise direction. In doing this, please ensure the correct position of the two black gaskets 7.1 and 7.2 at the two halves of the handle! When replacing the battery, please also replace the two gaskets by those provided with the new battery. 3(5)3(5)627.17.2174ca. 25mm+-+CAUTION!On incorrect polarisation, the probe will not function. Both the battery and the electronics of the probe can be damaged. Please ensure correct polarisation of the battery.
3 Prepare Probe103.2 Safety advice for lithium batteriesÖwww.tadironbatteries.de3.3 Disposal of lithium batteriesPlease only replace a lithium battery by an identical type. Please dispose of all batteries in accordance with the statutory regulations accordingto the Circular Economy Act and the Waste Act as well as the local provisions. The contact points of batteries that have not completely been electrically dischargedmust be insulated. Disposal together with domestic waste is expressively prohibited.You can deliver them cost-free at local collection points or in retail shops in your prox-imity. 3.4 Apply colour code of the probeFigure 4: Apply colour code onto the probeIn the factory, the probe is provided with four coloured silicone rings (white, green,red and blue), by means of which the probe can unambiguously be optically classi-fied. These rings can be individually combined and are slid onto the shaft of the probe. Intotal, 25 options of colour combination coding can be obtained through this.
114 Range of Transmission4.1 General remarks on wireless transmissionRadio signals are magnetic waves with their signal becoming weaker on their pathfrom the probe to the receiver (this phenomenon is referred to as loss). Both the elec-tric and the magnetic field strength are decreased inversely proportional to thesquared distance between the probe and the receiver. In addition to this natural limitation of the range of transmission, a reduced transmis-sion range can also occur due to other circumstances: • Reinforced concrete walls, metal devices or surfaces, heat insulation or metal evaporated heat protection glass reflect electro-magnetic waves and therefore a so-named radio shadow or blind spot occurs behind such objects. • Radio shadows within the transmission link• The antenna is installed in too low a position, therefore mount antenna in as high a position as possible above the floor within a visual range between probe and receiver. A few guiding values on penetration by radio signals:The maximum transmission range between the probeprobe and the receiver is 300meters in a free field. Ideal reception can be obtained if visual contact can be main-tained between the receiver and the probe. In case the receiver is installed in a switching cabinet, behind concrete walls or con-crete ceilings, it is indispensable for the antenna to be installed in a wall-mount fash-ion and including an antenna conduit. 4.2 Impairment of the range of wireless transmission Collision due to prevalence of too many probesFor a comparatively large number of probes, the transmission interval should not beset too short, as otherwise the transmission frequency will superfluously be occu-pied. A short interval means a higher volume of data on the selected frequency, whichcan lead to collisions with other probes. Through such collisions telegrams might bedestroyed during radio transmission. Materials Penetrationwood, gypsum, non-laminated glass 90 to 100%walling/brickwork, chipboards/fibreboards 65 to 95%glass-fibre reinforced concrete 10 to 90%metal, aluminium casings 0 to 10%
4 Range of Transmission12Figure 5: Telegrams of one probe are transmitted to the receiver collision-free. Figure 6: Telegrams of various probes increasingly collide in the air as the transmis-sion medium. Figure 7: Increase of faults in dependency of the number of probes (Interval of transmission 1 s)
134 Range of TransmissionAs illustrated in figure 7, the fault curve climbs steeply, if a critical number of probesis reached, as the air, functioning as the transmission medium, is increasingly occu-pied. Even with as few as two probes, faults cannot be excluded to 100%. For this reason, limitation to a maximum number of 16 probes is recommended forthe shortest transmission interval of 1 second, as the fault ratio already strongly in-creases from 24 probes. External probesHowever, faults can also arise for a small number of probes; they may be caused byother influences from the environment. External probes might also use the same frequency. In the event that they operatewithout the „Listen before Talk“ function, they arbitrariliy transmit information on thesame frequency without observing the operations and priorities of the other probes.Hence, if for example a probe transmits its radio telegram, and an external probe issimultaneously doing the same, the radio telegram will be destroyed. As the probesare not able to check their own transmission while transmitting, a fault will not be de-tected.Electrical equipmentIn crude industrial environment radio telegrams can be destroyed for examplethrough frequency converters, electric welding equipment or insuficiently shieldedPCs, audio-visual equipment, electronic transformers, ballasts, etc. Other compo-nents may also generate bursts that are located on the same frequency. Determination of the maximum number of probesIn the event that for a transmission interval of 1sec a number of more than 16 probesis to be installed, a longer transmission interval must be set, in order for the fault ratenot to increase further. Example:For an even further increase of the number of probes, the following example illus-trates the calculation below. Example:From a transmission interval of ≥3 sec the telegram will be sent twice. As a conse-quence, the number of applicable probes is reduced by half. The same phenomenon re-occurs for a transmission interval of ≥60 sec. From thistransmission interval, the telegram will be sent three times. Elimination of FaultsAt the receiving end, fault arising through lost telegrams - regardless whether throughexternal sources of interferrence or through collisions due to a large number ofprobes - can be bypassed by means of the parameter „radio-timeout“. The value last16 probes wiht 1 sec transmission interval ־ 32 probes with 2 sec transmission interval16 probes with 1 sec transmission interval ־ 48 probes with 3 sec transmission interval (theoretically)16 probes with 1 sec transmission interval ־ 24 probes with 3 sec transmission interval (effectively)
4 Range of Transmission14received will then be maintained over 2 … 10 transmission intervals and only then thealarm radio-timeout will be activated (display „----“). Through this function short-term faults or interferrences will be bridged and to do notlead to an error. NOTE!For collisions due to too large a number of probes, the factors „number of probes“, „trans-mission intervals“ and at the receiving end „radio-timeout“ must be observed and modified,if applicable.

5 Setup-Program185.3 Enter customised parameters via the setup program ExplicationsProbe identification (probe-ID)The probe identification (probe-ID) is an unambiguous number with a maximum of 5positions, that is recognised by the receiver. The ID can individually be modified, e.g.in order to obtain a better overview for a machine. However, it must be observed thatone ID is only allocated once within a company, as probes with the same ID cannotbe distinguished by a receiver, even for large distances.Transmission intervalThis parameter defines, in what interval data will be sent to a receiver. The setting ofthe parameters „transmission interval“ has an effect on the service life of the battery.Therefore, the selection should be made with caution and not exclusively in conside-ration of the transmission quality.Transmission frequencyThe transmission frequency determins the frequency band, in which the data will betransmitted to a receiver. In Europe, the transmission frequency has been set to868.4 MHz, as special regulations have been determined for the ISM band (industrial-scientific-medical) with regard to transmission interval and transmission power.In the 915 MHz-frequency band ten frequencies may be configured.Parameters As of factory Value range / selection Identification of the probe(probe-ID)deactivated 1to 99999transmission interval 10s 1 to 3600sectransmission fre-quency868,4 MHz915 MHz868.4 MHz for 868 MHz-hardware912.6 MHz for 915 MHz-hardware913.0 MHz913.6 MHz914.0 MHz914.6 MHz915.4 MHz916.0 MHz916.4 MHz917.0 MHz917.4 MHzNOTE!For a transmisison interval of > 10 sec, a so-named link telegram will be transmitted by theprobe, i.e. for a period of 30 minutes, telegrams will be transmitted in the 10 sec interval asset by the manufacturer, only after this period, telegrams will be sent in the set interval.NOTE!As soon as the setup plug is plugged in, the probe automatically transmits telegrams in atransmission interval of 1 sec, in order for the receiver to immediately recognised the modi-fications. After disconnecting the setup plug, the telegrams will be sent in the set transmis-sion interval.
