1. Product Description
ZAIoT-VTC01 is a low-power design, plug-and-play wireless vibration and
temperature integrated collection terminal product, with high-precision
vibration acceleration and temperature collection functions. The product
has built-in 10kHz (Z-axis) and 6kHz (XY-axis) high-frequency response
acceleration and temperature sensors. By carrying the ZETA high-speed
protocol, the original waveform can be transmitted while ensuring
wide-coverage communication performance, and the effective
communication line-of-sight is greater than 800 meters. Powered by a
large-capacity lithium sub-battery, it can work continuously for 3 years at
a typical transmission interval (6h). At the same time, the product has
built-in end-side analysis and AI alarm algorithms, and can flexibly
configure various combination strategies of original waveform and feature
edge calculation to meet the needs of multiple use scenarios. The product
complies with IEC 60079 intrinsically safe explosion-proof standard, the
explosion-proof mark is Ex ia IIC T4 Ga, and the operating environment
temperature is -20℃~+60℃. Suitable for industrial and chemical
scenarios.

4. 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
of measurement points for each equipment model.
Step2 - Surface treatment
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.
Check the grounding of the equipment before installation to ensure safe use.
Step3 - Sensor installation
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.
Installation direction: vertical, horizontal and axial are all possible.
Step4 - Sensor online
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

ZAIoT-VTC01

when shipped).
Check the status of the terminal on the platform to see if it is online.

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

6.4. 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

terminal is successfully connected. If unsuccessful, operate the button to
restart once.

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
