How to troubleshoot communication failures in EC60 RTU and radar level meters?

EC60 RTU troubleshooting: check 4G signal, power supply, Modbus parameters, radar output in 6 steps

EC60 RTU terminals and radar level meters communication troubleshooting requires systematic diagnosis. Start by checking 4G signal strength and verify device power status and parameter configuration for optimal performance.

  • Step 1: Check 4G signal strength (>-85dBm) and SIM card status
  • Step 2: Verify RTU power supply voltage (solar panel 12V output)
  • Step 3: Confirm Modbus address, baud rate, and parity settings
  • Step 4: Test radar level meter FMCW signal output
  • Step 5: Test local serial communication vs remote communication
  • Step 6: Review RTU operation logs and error codes

For HZ-KSLF radar flowmeters, focus on antenna installation angle and measurement distance within effective range. The ultra-low power design of EC series RTU automatically enters sleep mode during low voltage conditions to preserve battery life.
