Ultra RF Analogue Transmitter Manual System Concept RF Transmitters connect to sensors or meters and send data to the infrastructure internet connected Gateway on site The Gateway stores and transfers the data to the Realtime Online cloud server over a ...
Ultra RF Analogue Transmitter Manual 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 ...
Ultra RF Analogue Transmitter Manual 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: ...

Ultra RF Analogue Transmitter Manual 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.

Ultra RF Analogue Transmitter Manual 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. ...
Ultra RF Analogue Transmitter Manual 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 ...

Ultra RF Analogue Transmitter Manual 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.

Ultra RF Analogue Transmitter Manual 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. ...

Ultra RF Analogue Transmitter Manual Each Transmitter will show the following Sensor ID Transmitter Type Battery Voltage Values being received 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 ...
Ultra RF Analogue Transmitter Manual 5. Dashboard configuration Following successful login to Realtime‐Online™ with your username and password, create new sensor (System > Sensor Setup > Create New Sensor) Enter Sensor ID number located on the side of the Status Transmitter Name the Senor as required with reference to site requirements for ease of identification. Select Sensor Type = ‘Condition’ . Select unit = as desired in drop down menu. Select ‘Analog’ from dropdown. Fill in the analogue formula that relates to the 4‐20ma scaling for the device being monitored. Below shows *1, this setting with only show the actual mAreading being seen at the transmitter connection. If alerts are needed the delay before alarm can be set. The alert Day/Night Option can be switched on or off by selecting the option. Click ‘Create Sensor’ Example: Dual Input Status Transmitter ...
