(add up to 40 nodes) . After 5 minutes Enb_auto_add_sensors will automatically = 0. Memmap resgisters You can download Modbus Memmap of WS433-CL-FW_V1.9 with the following link: http://filerun.daviteq.com/wl/?id=fnepmO8uKmnp7P5R90Iu4osu8DcZlzjp 5.1.2 Add sensor node into WS433-CL-04 (1) through intermediate WS433-CL-04 (2) and Modbus In case the sensor need to be added to WS433-CL-04 (1) has been installed in a high position, the sensor cannot be brought close to WS433-CL-04 (1). - Page 5 5.3 Configuration 5.3.1 Sensor configuration The WS433-AC wireless sensor measures AC current via CT (Current Transformer). We need to check what the ratio on the CT is printed on the sticker. For example: 50/5A = 10, 75/5A=15, 100/5A = 20, ...
- Page 6 Next, we need to import the configuration file for WS433-CL-04 by importing the csv file: Go to MENU: FILE / Import New / => select the file with name Template for WS433-AC.csv (after unzip the file).
- Page 7 In the row Write_CT_Node , we write the the ratio of the CT of sensor node to co-ordinator id WS433-CL-04 by write the the ratio of the CT in column Setting Value then check the box Func to write the value => the value in the Read Value column show OK, that means the configuration is complete.
- Page 8 You can now connect the Co-ordinator WS433-CL-04 using an RS485 connection to read data from the wireless sensor. 5.3.2 IO Wiring On WS433-AC there are 2 wires marked S1 and S2, we connect the sensor to the current transformer according to S1 with S1 (K) and S2 with S2 (L) as shown below.

Page 9: Installation
6. Installation 6.1 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 two modules. In real life, there is no LOS condition. However, the two modules still communicate each other, but the distance will be reduced significantly. - Page 10 Carefully pull out the top plastic housing in the vertical direction NOTE: Because of O-ring, it requires to have much pulling force at the beginning, therefore please do it carefully to...
