Remedy
Ensure that flow computer is operational and
that Ethernet cables are connected.
Ensure that flow computer is operational and
that Ethernet cables are connected.
Close cabinet door.
Set sealing switch to "sealed" position.
Restart HMI computer.
Ensure that Power Supply 1 is switched on.
Replace power supply if necessary.
Ensure that Power Supply 2 is switched on.
Replace power supply if necessary.
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.
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.
