If your devices are pre-configured by us, please go through the user-friendly procedure to get started with your ER Beam system, which takes only a few minutes to get the process rolling. 1 Power on Gateway and turn on its inbuilt Wi-Fi network. 2 Connect your Android phone to the ER Beam Wi-Fi network. 3 Connect the Android cable to the phone first using the OTG adapter. 4 Open the ER Beam Offline Android app. 5 Load the project and tap on it to go to the home screen of the app. 6 Then connect the Android cable's other end to the Node and click on Setup Device and follow the wizard. 7 Repeat step 6 for all your Nodes. 8 Then press the Cloud Sync on the app to sync back all the Node settings to the gateway. 9 Now the Nodes will send the sensor data at the configured time intervals. 10 Optionally, the data can be exported and engineering conversions can be set using the Gateway software. Page | 1 Users Manual Analog Node 2 SETTING UP WIRELESS ANALOG NODE This section provides information on setting up an Analog Node to work with the offline ER Beam gateway. 2.1 Installation The Nodes can be directly affixed to a flat surface using M6 screws. However, for more sophisticated mounting scenarios, we recommend using the node bracket. The node bracket can be used to easily mount the node on flat surfaces, on pipes using U-bolts or cable-ties, or in other complicated settings. If you are using the bracket, first fix the node device to the bracket using M6 screws and nuts as shown below. For four channel devices (BEAM-AN-S4), use M4 screws to mount the nodes to flat surfaces or brackets. Figure 1: Attachment for nodes Use four screws and nuts to attach the node to the bracket (Refer to figure 1). Connect the SMA antenna to the bulkhead. Once the mounting is complete, the node should look as in figure 2. Figure 2: Node (after installation) Page | 2 Users Manual Analog Node 2.2 Node Setup 1 Connect the node antenna to the antenna bulkhead. 2 Connect the sensor wires to the node while ensuring that the wires are plugged in correctly.

(See the Gateway section to learn about switching on the ER_Beam Wi-Fi network.) 2 Connect the Android smartphone to the Node via an OTG adapter. NOTE:
Please make sure the Node is switch off before connecting to your Android phone. 3 Switch on the Node. 4 Open the ER Beam app on the phone. NOTE:
You need to add the Node and create the project first before you commission the tilt meter. Please refer to Gateway Setup section in the users manual for Gateway for details. Page | 4 Users Manual Analog Node
(i) Search for the project, which you have already created once you open your ER app. Select and click the button to download the project and enter in to the project, where the project details would be mentioned. Page | 5 Users Manual Analog Node
(ii) Click on Setup Device on the menu (at the bottom of screen), the app will show connected node information.
(iii) Optional Step: If Wireless Mesh (Relay) function is to be deployed, click on "Wireless Mesh" toggle button to enable. Once
(iv) done, click on Setup Sensor, you can now configure the sensor settings Page | 6 Users Manual Analog Node
(v) After clicking Setup Sensor, sensor setup page will open with the available channels Tap the Arrow icon on the respective channel which your sensor is connected to.
(vi) Sensor setting can be made as follows:
Sensor Code: Desired sensor name. Sensor Type: Select respective sensor type. Parameters: Turn on the parameters as connected to the Node. Excitation time: Set the warm up time required for the sensor. Excitation Voltage: Select either 5 or 12 or 24, depending on the sensor. Page | 7 Users Manual Analog Node
(vii) Click Save Settings. The Node will now read the configured sensor.
(viii) On next page, you will see the first reading.
(ix) To get another reading, click on the arrow icon. If the reading is ok, enable the sensor by switching on the android icon (colour changing to blue). Page | 8 Users Manual Analog Node
(x)
(xi) Repeat above steps to configure other sensors connected to the Node. Once all sensors are configured, click on Enable Sensor button. It will take you to next page Scanning Network which will scan the wireless signal strength (RSSI) between the Node and Gateway.
(xii) After receiving the Network Test information, if you need to, you can perform another network test by pressing the button located at the lower right corner. Page | 9 Users Manual Analog Node
(xiii) Next, click Start Monitoring button then the app will prompt, Device commissioned. Click OK.
(xiv) Press the Project Sync button at lower right area to send all the configuration information back to the gateway. Page | 10 Users Manual Analog Node
(xv) If you would like to get the Node to immediately send a reading to the Gateway, press the SYS TEST button on the devices printed circuit board as shown below.
(xvi) For commissioning of additional Nodes, repeat the above steps.
(xvii) Now proceed to the Gateway software dashboard on your Laptop and click on your project. Now you will be able to observe your commissioned devices under Device Summary Section. For further configuration, refer to the users manual # WI6002.117 on Gateway. FCC Caution:
