Installation guide Step1 - Measurement point selection Sensors are generally deployed on flat surfaces with high stiffness on the equipment, as close as possible to the rotating bearings, such as the drive end bearings of motors. Please refer to national and industry standards for the number and location Step2 - Surface treatment of measurement points for each equipment model. The mounting surface should be as flat as possible, if necessary sandpapered and cleaned with acetone to remove oil and dirt. The bottom surface of the installation can be coated with a suitable amount of silicone oil to increase the accuracy of the vibration signal. Step3 - Sensor installation Check the grounding of the equipment before installation to ensure safe use. The sensor supports three types of mounting: magnet, adhesive and M5 bolt, with the threaded connection mounting being preferred. If the equipment does not have the conditions for drilling, a transition plate can also be used to thread the terminal first and then weld the transition plate to the surface of the equipment. If magnetic adsorption is used, the terminal can be fixed by applying quick-drying adhesive on the bottom surface and silicone around the outer ring to play a sealing and long-term fixing role. Step4 - Sensor online Installation direction: vertical, horizontal and axial are all possible. Ensure that the gateway is powered up and covered by the ZETA network and add the terminal to the platform. Press and hold the button on the front of the terminal for 5 seconds, the device powers up and the blue light flashes to indicate that the terminal is attempting to register the gateway (the internal battery was powered up 6 ZAIoT-VTC01 when shipped). Check the status of the terminal on the platform to see if it is online. 7 5. Operating Instructions 5.1.

9 ZAIoT-VTC01 Among them, the following parameters need to be set according to the function of different rotating machinery:

Acquisition of raw vibration data according to the configuration period and wirelessly backhauled through ZETA-H protocol The sampling frequency and the number of spectral lines can be configured The acquisition cycle can be configured Support different terminals to send and set synchronous acquisition time 10 5.3. Check Status ZAIoT-VTC01 After the device is added, you can view the data of the added device in the list. When the device is powered on, the online status will change from

"offline" to "online", and the startup time, registration time and heartbeat time are updated. If the data is underlined, you can click to view the detailed data Click the device ID to view the detailed status, as shown below:

Battery replacement When the platform reports a "low battery" alarm, please replace the battery promptly. Replacement procedure Unscrew the four screws securing the terminal housing and open the housing by gently lifting upwards. Unplug the old battery from the battery supply plug on the PCB. Replace the battery with a new one, taking care to snap it in place and insert the battery supply plug to the PCB. Cover the housing gently and tighten the 4 fixing screws, taking care that the side with the buttons and indicators corresponds to the front of the PCB. The battery will automatically start the terminal registration when it is powered up, the blue indicator light flashes, check at the platform if the 13 ZAIoT-VTC01 terminal is successfully connected. If unsuccessful, operate the button to restart once. 14 ZAIoT-VTC01 7. Common faults and precautions Device cannot connect to network Check that the gateway is powered up to ensure ZETA signal coverage is in place Check the detection cycle, if it is offline after a proper connection, even if the gateway is properly powered up, you still need to wait for the detection cycle to arrive before you can complete the connection, at this point you can initiate the connection via a button restart, which is the fastest means Check the power level reported on the last platform to see if there is a possibility of low battery Battery power drops badly Collection cycles are too frequent, a collection frequency of 4 hours/time or more is recommended Check signal quality, poor signal and frequent dropouts and uplinks will accelerate power consumption Periodically check the installation of the terminal for any loose or displaced measurement points Deploy the terminal in a suitable location with reference to the operating temperature range and protection class Replace the battery in case of a low battery alarm 15 8. Safety instructions ZAIoT-VTC01 1. Potential electrostatic charging hazard: clean only with a damp cloth. 2. Only ER26500 lithium thionyl chloride battery produced by EVE Energy Co., Ltd. is allowed to be used as the power supply. Do not charge the battery.
