FAQ

Q: How to do when the RS485 network communication fault?

A: Please first confirm whether the RS485 wiring is loose, AB reverse connection and other problems, and then click the key to check the table of general parameters Numbers, such as address, baud rate, check bits, etc., are set correctly.

Q: How to do when the LoRa communication fault?

A: Please use the USB to 485 serial port line to connect with the instrument RS485 interface, and read the parameters in the table through communication. Verify whether the parameters in the table are the same as the wireless configuration of the upper main station (channel and spread spectrum factor). If they are different, please modify the instrument wireless parameters to be consistent with the master station and then test again; If the same, it may be the instrument and the master station. Too far apart or serious field interference, at this time can try to use an external suction cup antenna, or consider the nearby new wireless master and test again.

Q: What is the difference between ordinary secondary access and W (type external transformer)?

A: General secondary access to the built-in transformer. The transformer is selected according to the actual current on site.Model W comes with external transformer (can not be disassembled, otherwise it will burn the meter). The transformer has been installed on site for easy wiring and free of disassembly.

Q: What are the meanings of 3×57.7/100V, 3×220/380V, 3×380/660V, 3×100V, 3×380V, 3×660V?

A: 3*100V, 3*57.7/100V used for high voltage, with voltage transformer. 3*100V stands for 3P3W, 3*57.7V/100Vstands for 3P4W; 3*380V, 3*220V/380V, 3×660V, 3×380/660V used for low voltage, with voltage directly input. 3*380V, 3×660V stands for 3P3W, 3*220V/380V, 3×380/660V stands for 3P4W.
