Product Introduction WiSenMeshWAN® Voltage Interface Node - User Manual The WiSenMeshWAN® Voltage Interface Node is one of the key products in our patented WiSenMeshWAN® geotechnical safety monitoring system. Working together with the WiSenMeshWAN® gateway product and the specified voltage type sensors, it intelligently delivers the real-time data of voltage type sensors to the information centre. The WiSenMeshWAN® Voltage Interface Node operates using our core technology, i.e., the WiSenMeshWAN® Low Power, Intelligent, Wireless Sensor Network protocol, together with its internal high precision voltage sample module and power unit. This product satisfies the three fundamental identities of the system: A. Network Life Span: to maximise battery life across the mesh network as a whole; B. Network Data Arrival Rate: to minimise data packet loss; C. Single Node Environmental Coverage: to maximise radio coverage. Our product has IP66 and is designed to work in a tough environment. It is small in size, reliable in performance, easy for maintenance, has high precision during sampling, and has strong immunity to radio-interference. Figure 1.

No.2021 4. Terminologies WiSenMeshWAN® Voltage Interface Node - User Manual Figure 3. Voltage Interface Node Internal Configuration Terminologies 5. Operation Procedures 5.1System Deployment Notifications 1) Location: The deployment location of a Voltage Interface Node is usually determined by the required monitoring or inspection location; 2) All the Serial Numbers of a Unit must be recorded against their site references; 3) Before any Voltage Interface Node is switched on, two tasks will need to be carried out: A. Unlike the Tilt Node which has a MEMS tilt sensor embedded in the node, the Voltage Output sensors chosen by the customer must be connected to the Voltage Interface Node; B. The connections between a customer chosen Voltage sensor and a Voltage Interface Node must strictly follow the rules stated in this document; C. A gateway must be deployed, powered on and proven to be working properly. Otherwise, the nodes will need to be switched off, then switched on again after a gateway is switched on. So simply speaking, the rules www.wisencn.com Page - 8 - of 13 Wisen Innovation Technical Doc. No.2021 to follow to correctly deploy a WiSenMeshWAN® system are: WiSenMeshWAN® Voltage Interface Node - User Manual Gateway first, then nearby nodes, then further nodes. 4) During deployment, the Serial Number, i.e., SN of a node and the orientation of the Voltage sensors deployed against their site references must be recorded; 5) All the node should have its antenna point upwards. 5.2Deployment Procedures 1) Open the box: Take the node out of the package and open its lid; 2) Insert Battery: By default, a node does not contain a D-Cell battery. Therefore the battery needs to be inserted. Notice : +ve and ve orientation must be correct, otherwise, the internal circuit may be damaged, special attention must be paid to avoid shorting the battery by the battery holder. 3) Antenna Installation: screw the antenna tightly onto the node; 4) Sensor Installation: To ensure a customer chosen Voltage sensor is deployed onto a structure correctly, please strictly follow the corresponding manufacturer sensor instructions. 5) Sensor connections to Node: A. Strip the cable sleeve back by 8mm. B. The 3 wires from the cable are Vcc_Out, In1 and GND. Please refer to the sensor datasheet to identify the purpose of the stripped wires. C. Untighten the gland cover, insert cable through the gland, then connect the 3 wires accordingly. D. Once the wires are connected, please tighten the gland cover firmly to ensure its IP rating on that channel. Notice 1: The cable gland diameter of the Voltage Interface Node is 8mm. Notice 2: All the 3 wires must be connected, to minimise electrical interference and possible loss of precision. Notice 3: Within any electrically noisy environment, nodes with sensors must be >= 0.3m away from the source of the noise. 6) Sampling Range Selection: "Vcc_Out Switch" is used to select the option of: A. Sampling "Voltage Signal Output Range" from an external sensor; B. Providing "Input Power Voltage" to an external sensor, e.g., for 6C01 type, "Vcc_Out Switch" of 2.5V must be selected so that the EC-5 soil moisture sensor can be powered at 2.5V and also the node can sample between 0 and 2.5V from the sensor. Notice: For any other sensors, please check against the sensor specification before the setting is completed www.wisencn.com Page - 9 - of 13 Wisen Innovation Technical Doc.

Vcc_Out Switch Setting. 7) Power On: once all the Voltage sensors are connected, turn the switch on. Now you should be able to see 3 LEDs flashing 3 times, which means the node is on. Then switch off the node to save power if the gateway is off; 8) Tighten the 4 Cap-Hex-Head screws of the lid to secure the enclosure IP rating; 9) To validate the sensor data, please visit Wisen Visualisation Platform for further details. 5.3Mounting Options Voltage Interface Node can be deployed with various methods. However, the priciple is to make sure it is firmly attached to the installation surface. 6. General Maintenance and Notification 1) Once Voltage Interface Node is installed in the field, please minimise any man-made disturbance so that data quality can be maintained; 2) Radio communication will be impaired if the antenna is covered by metal or very moist soil material; 3) Due to the discharge characteristics of the recommended battery, a battery replacement should be carried out when a node reported voltage reaches 2.7V, at which point you have approximately 3 weeks to change the battery; 4) Our product will use all the possible capacity in a battery down to a stop (minimum) voltage, which has been specified in the Features table. When this occurs, our WiSenMeshWAN® protocol will send you a warning then it will enter a deep sleep mode until a new battery is installed; 5) If the data from nodes are showing unexpected results or are not being sent back to the Wisen gateway, then please carry out investigation using the following two stage procedure: www.wisencn.com Page - 10 - of 13 Wisen Innovation Technical Doc. No.2021 A. Remote Inspection of historical data, to identify the following: WiSenMeshWAN® Voltage Interface Node - User Manual a) Whether the heart-beat message has been sent back successfully at each time interval; b) Whether the battery voltage is too low, if yes, please change the battery unit; c) Whether the signal strength has become significantly weaker than it was previously. If yes, please check the antenna has been screwed on firmly. B. On-site Inspection: If all the above are good, please arrange an on-site inspection to check: a) Whether a Node has visible external damage; b) Check the box lid to see if it is firmly tightened; c) Whether the antenna is bent or damaged and that the node is not blocked by new construction, e.g., hoardings; d) When it is possible, check that the signal strength is normal by using a spectrum analyser; e) Open the lid, to see whether the battery is firmly attached to its holder; f) Use a multi-meter to measure the battery voltage. If it is below the stop (minimum) voltage, replace the battery. g) Make sure the 3 wires are connected properly, if necessary, please disconnect the wires to inspect. Notices : i. Case One: If any change has been made from the list above, please inspect the data at the remote server; ii. Case Two: If all the actions from the list above have not cured the problem, please contact Wisen. We will be happy to help. 7.
