Product Usage Instructions

• Installation
  • To install the Wireless Piezo-electric 10Khz Vibration Sensor, follow these steps:
  • Choose a suitable location for the sensor installation.
  • Ensure that the sensor is securely mounted using the provided M6 screw.
  • Make sure that the sensor is tightly sealed to prevent any moisture or dust from entering (IP67 protection).
• Powering the Sensor
  • The Wireless Piezo-electric 10Khz Vibration Sensor is powered by a single AA 1.5-3.6VDC battery. To power the sensor:
  • Open the housing of the sensor.
  • Insert the AA battery into the designated slot.
  • Close the housing securely.
• Configuration
  • The sensor comes pre-calibrated and does not require any additional configuration. However, if you need to change the Rdata rate, you can do so by using the button on the sensor.
• Measurement Process
  • The Wireless Piezo-electric 10Khz Vibration Sensor measures vibrations using a sampling time interval. Here’s how the measurement process works:
  • At the specified sampling time interval (e.g., 2 minutes), the sensor node wakes up and supplies power to the external sensor for measurement.
  • The external sensor takes a certain time to complete the measurement (e.g., 200mS).
  • After the measurement is finished, the node reads the raw value from the sensor.
  • The raw value can be scaled using the formula Y = aX + b, where X is the raw value, Y is the calculated value, and a and b are constants.
  • The scaled value is then compared with the Lo and Hi thresholds for alarm processing.
• Alarm Processing
  • The alarm processing is based on the comparison of the scaled value with the Lo and Hi thresholds. The status bytes of the sensor node indicate the error code and sensor type. Here are the error codes and their descriptions:

Please take out the battery for 20 seconds, then install it again
to reset the node and recognize the new sensor module.

Typical Applications

Operation Principle

Process of measurement

• When the sensor sampling time interval is reached, For example 2 minutes, the node will wake up and switch ON the power supply to supply the energy to external sensor to start the measurement.
• Depends on the type and characteristic of external sensor, the sensor will take a certain time to finish the measurement.
• For example: the measurement time is 200mS, after this time, the node will read the value of sensor, node will switch OFF power supply to external sensor to save energy.

The measured value is the raw value of the sensor. The measured value can be scaled according to the following formula:

Y = aX + b

• X: the raw value from the sensor
• Y: the calculated value for parameter 1’s value or parameter 2’s value
• a: constant (default value is 1)
• b: constant (default value is 0)

So, if there is no user setting for a and b ==> Y = X The Y value will be compared with Lo and Hi threshold. Please refer below the graph of alarm processing.

Add sensors node to Co-ordinator WS433-CL Add Sensor Node ID automatically

• Step 1: After supplying power the Co-ordinator via M12 connector, the Node ID must be registered within the first 5 minutes, up to 40 WS.
• Step 2: Bring the wireless sensor closer to the Co-ordinator’s antenna then take off the wireless sensor battery, wait for 5s then insert the battery again. If:
  • Buzzer plays 1 peep sound, LED blink 1 time, that means registering Node ID on Co-ordinators uccessfully.
  • Buzzer plays 2 peep sounds, LED blink 2 times, that this Node ID is already registered.

If you do not hear the “Peep” sound, please disconnect the power the co- ordinator, wait a few minute and try again.

• Node id added in this way will be written to the smallest node_id_n address which is = 0.
• Set Rssi_threshold (see RF MODE CONFIG (in the Modbus Memmap of WS433-CL), default -25): The case if Coordinator is on high position and need to add node sensor. We set the sensor as close as possible and set the
• Rssi_threshold to -80, -90 or -100 to increase the sensitivity to allow WS433-CL-04 can add sensors at a longer distance. After that, perform 2 steps of adding sensors and then reset Rssi_threshold = -25.
• Enb_auto_add_sensors configuration (see RF MODE CONFIG (in the Modbus Memmap of WS433-CL)): In case you do not want to turn off the power WS433-CL, you can set Enb_auto_add_sensors = 1, this way we have 5 minutes to add nodes (add up to 40 nodes) . After 5 minutes
• Enb_auto_add_sensors will automatically = 0.

Button Function

Open the cover of sensor then use the push button to set the data transfer speed for the first 30 seconds when the battery is first installed, after 30 seconds the push button function does not work.

• Press and hold the button for 2 seconds => LED blinks once => Release the button to set Data rate RF 50kbps
• Press and hold the button for 5 seconds => LED blinks twice => Release the button to set Data rate RF 625bps
• Press and hold the button for 10 seconds => LED blinks 3 times => Release the button to reset RF parameters (frequency, RF output power, data rate), if held for more than 30 seconds then the button function does not work.

Reset default WS433:

• Frequency: 433.92 MHz
• RF transmit power: 15 dBm
• RF data rate: 50 kbps

Configuration

First, you need to prepare

• Num of Node will indicate the number of nodes managed by WS433-CL.
• Every time a node is added, the Num of Node will increase by 1.
• Every time a node is deleted, the Num of Node is reduced by 1.
• Writing Num of Node = 0 will delete all 40 node ids to 0.
• If you want to delete a node id, then write it = 0 with theW rite function is 16 and the Read function is 3.

1. Step 1: Connect Antenna, RS485 – configuration cable and power supply co-ordinator
2. Step 2: Open Modbus tool on PC
   • You can download Daviteq Modbus Configuration Tool with the following link:https://filerun.daviteq.com/wl/?id=qK0PGNbY1g1fuxTqbFW9SXtEvCw7bpc6.

   • How to use the Modbus configuration software
   • Unzip file and run file application “Daviteq Modbus Configuration Tool Version”
   • Choose COM Port (the Port which is USB cable plugged in)
   • Set the BaudRate: 9600,
   • Parity: none
   • Click “ Connect “ untill the Status displays “disconnected” to “connected“. It means the WS433-CL-04 is being connected with computer;
   • Next, we need to import the configuration file for WS433-CL-04 by importing the csv file: Go to MENUF: ILE / Import New / => select the template file.
3. Step 3: Configure parameters of the sensor.

Installation

Installation location

• Wireless sensor utilize the ultra-low power 433Mhz RF signal to transmit/receive data with Wireless co-ordinator.
• To maximize the distance of transmission, the ideal condition is Line-of-sight (LOS) between the Wireless sensor and Gateway.
• In real life, there may be no LOS condition. However, the two modules still communicate each other, but the distance will be reduced significantly.

ATTENTION:

• DO NOT: cover the Wireless sensor or its antenna inside a completed metallic box or housing, because the RF signal can not pass through the metallic material.
• NOTE: Integrated WS433-CL / iConnector Coordinator The coordinator must be placed at least 4 meters above the ground and the WS433-V1A clearly visible.

Dimensions

• Unit: mm

Process mounting

WARNINGS:

• The sensor should be mounted on an oil-free and grease-free surface as close to the source of vibration as possible.
• For best results, the sensor should be mounted via a drill hole and have anM 6×1.0 threaded hole (an adapter can be used) attached directly to the housing.
• Please make sure that the operating ambient temperature is right for the sensor.
• Prepare the professional tools for installation. The inappropriate tools may cause damage to the sensor.
