Remedy
Check wiring of 4 to 20-mA signal at analog
input.
Check sensor.
Check wiring of 4 to 20-mA signal at analog
input.
Check sensor.
Check wiring of 4 to 20-mA signal at analog
input.
Check sensor.
Restart flow computer.
If error persists, contact Endress+Hauser.
Restart flow computer.
If error persists, contact Endress+Hauser.
Restart flow computer.
If error persists, contact Endress+Hauser.
Check wiring of 4 to 20-mA signal at analog
input.
Check sensor.
Check wiring of 4 to 20-mA signal at analog
input.
Check sensor.
Install application on a 3rd generation or newer
flow computer.
This is normal behavior following an intended
restart.
In any other case, contact Endress+Hauser.
Check wiring of Modbus RTU (RS-485) cables.
Ensure that Promass is switched on. Check
Modbus RTU communication settings.
Restart flow computer.
If error persists, contact Endress+Hauser.
