1. Introduction The Analogue transmitter defined in this specification is designed to measure the ma output being generated by the compatible chosen equipment for monitoring. For example, there are numerous analogue devices used in the HVAC controls world. Typically, analogue output devices are used to provide modulating control of valves, dampers, electric motors through variable speed drives and a wide variety of other devices. The most common devices associated with analogue outputs are sequencers, variable speed drives, silicon controlled rectifiers and actuators. After connection of the analogue transmitter in series with these circuits the operational status can be monitored. Commonly the analogue transmitter is used to monitor amps, pressure, water flow, level tanks, and Ph values when attached to the appropriate equipment supplying a analogue output. There are differences with equipment providing an analogue output, some devices have an output with a active voltage where this transmitter can be directly connected and others have a analogue output that needs exciting with a power supply. If this is the case the appropriate power supply would need to be connected in addition to the analogue transmitter to allow operation. The analogue transmitter is available in four different configurations, for compatibility to different applications and equipment: 4 20mA (3999 913 2095) 0 1 volt (3999 913 2110) 0 5 volt (3999 913 2111) 0 10 volt (3999 913 2112) Features A variety of available radio frequency options Small footprint Automatic data collection and transmission Wireless, range of up to 15km line of sight Battery powered with up to 3 year battery life Technical information Operating frequency 868MHz (Other frequencies available 915 MHz) Operating range up to 15km line of sight Suitable to monitor any device with a analogue output Storage Conditions: 0 C to +50 C Relative Humidity: 25% to 95% Operating Temperature: 0 C to 40 C Applications, any compatible meter/device with a analogue output i.e.: Flow monitoring PH value monitoring Tank Level Monitoring Invisible Systems Limited Page 4
2. Installation. The connection for the analogue transmitter is as follows; (Must always be connected to the appropriate energised analogue circuit) Red cable + Black cable These connections need to be connected in series with the appropriate circuit as they work on the same principle as an amp meter. See example circuit diagrams below for more information. 2.1 Fitting Example Most Realtime-Online sensors have a unique mounting clip on the battery compartment which allows the sensor to be installed: Mounted with screws through the mounting clip. Care should be taken when mounting and drilling holes in the designated area as the cables present on the inside of enclosures will need to be avoided Invisible Systems Limited Page 5
Below shows examples of different circuit diagrams with the 4 20 ma transmitter fitted in series (current loop) within the appropriate circuit. The other transmitters types referred to in this manual are wired in the same way; the 4 20 ma is shown as an example. Diagram 1 Diagram 2 Diagram 3 Invisible Systems Limited Page 6
Caution When connecting to this type of solution, the correct safety protocols for site would need to be followed when working on this type of equipment. It is recommended that the associated manual for the equipment being connected to be fimiliarised with prior to commencement of work. 3. Testing the circuit. An appropriate ma meter is required to enable testing of the circuit. As with the transmitter connection the ma meter is required to be fitted within the circuit in series before the transmitter connection. Below shows diagram 3 with a Multimeter connected in series. This allows for the analogue range being delivered by the device to be cross checked with the meter. Invisible Systems Limited Page 7
4. Sensor Numbering Each sensor is supplied with a unique serial number marked on the side together with a barcode which is used to identify the sensor on the Realtime Online dashboard. It is vital these numbers are accurately recorded otherwise it will be impossible to identify the sensor in ISL Setup or the server dashboard for the specific site. Note: a sensor number cannot appear more than once on the same site, but can appear on more than one site dashboard. 5. Locating Sensors Realtime Online Sensors use radio frequency communication to a local gateway. The distance between sensors and the gateway can also be very long (up to 15Km line of sight). However, environmental factors such as walls and furniture can reduce this distance considerably so optimal placement of sensors is important. Note; this document does not specifically cover the installation of Gateways which are covered in a separate document, (see index) but the following general guidance is given. When placing sensors, avoid the following: a. Placing the transmitter in metal enclosures such as a distribution boards. b. The transmitters are splash proof and are suitable for installation in outdoor areas, but are not 100% waterproof. Do not install them in positions where they are liable to be submerged. c. Do not install the transmitters close to other RF sources such as alarm systems, door openers or other radio systems. Although the amount of RF energy transmitted by the sensors is very small indeed, there is a possibility that they could interfere with other electrical devices, so they must not be installed close to other devices which could be affected e.g. medical devices or wireless alarm systems. When sitting the gateway, try to ensure the location is approximately equidistant in radio signal terms from all the sensors. Typically, sensors can be expected to pass through 4 5 normal internal walls without difficulty. Invisible Systems Limited Page 8
The following illustration shows how sensors which are hidden behind large metal objects like tanks or steel walls may have difficulty in transmitting to the gateway. Possible repeater location Notes Care must be taken when installing this sensor as live electrical circuits are usually within the vicinity. Seek to guidance of a qualified electrician if you are unsure. Battery For safety considerations, all wireless transmitters are transported with the internal battery disconnected. Usually this can be confirmed if the white connector is passing through the base. On first use it is therefore necessary to connect the battery following the steps below: 1. Remove the four screws at the base of the sensor. Then remove the base and the sealing gasket. 2. Carefully insert the small white plug into the PCB socket and ensure the cable passes through the notch to avoid pinching. See diagram below. 3. Replace the sealing gasket, cover and 4 screws. DO NOT OVERTIGHTEN! Invisible Systems Limited Page 9
4. Checking operation Following installation of the Pulse transmitter, it is suggested that the operation is checked to ensure the transmitter is being received by the Gateway. Open Ultra RF Gateway Setup This should be located on the desktop of your laptop. On first use, if requested, select the USB lead being used and highlight for use. Name lead connection and select it in drop down list Screen information being displayed. The Screen will show the transmitters it can see in range of the receiver; these can be sorted by sensor type or ID as per preference. Invisible Systems Limited Page 10
Each Transmitter will show the following 1. Sensor ID 2. Transmitter Type 3. Battery Voltage 4. Values being received 5. Signal Strength and frequency It is important to check all of this information to confirm that each sensor is being seen by the gateway and at regular intervals in relation to (5). Blue colour dots show direct messages being received and Orange colour dots show messages received via repeaters. Correct setup and operation of Realtime online, will require all the Sensor ID s and Transmitter types in conjunction with the Gateway ID. The RSSI is shown in dbm with a bar chart showing signal strength. This is an important parameter. The table below shows dbm ranges in relation to Signal strength. The range shown above reads 100dBm this is shown in the table as a Marginal signal therefore will need improving either by reviewing the transmitter location, moving the Gateway closer or adding a signal repeater in between transmitter and receiver. Value RSSI Signal RSSI Signal Value dbm Strength dbm Strength 2 109 Marginal 17 79 Good 3 107 Marginal 18 77 Good 4 105 Marginal 19 75 Good 5 103 Marginal 20 73 Excellent 6 101 Marginal 21 71 Excellent 7 99 Marginal 22 69 Excellent 8 97 Marginal 23 67 Excellent 9 95 Marginal 24 65 Excellent 10 93 OK 25 63 Excellent 11 91 OK 26 61 Excellent 12 89 OK 27 59 Excellent 13 87 OK 28 57 Excellent 14 85 OK 29 55 Excellent 15 83 Good 30 53 Excellent 16 81 Good Further technical reference and product info can be obtained from associated data sheets Invisible Systems Limited Page 11
