Causes and remedial action
Warnings
C485
When the simulation of conductivity or buildup is active, the device displays a warning.
‣
Deactivate simulation.
S825
Ambient temperature outside of specification.
‣
Operate the device in the specified temperature range.
S971
The measured value is outside the set sensor range.
‣
Operate the device in the configured measuring range or set the measuring range.
Faults
F270
Electronics/sensor defective.
‣
Replace device.
S803
Impedance of load resistance at analog output too high.
‣
Check the cable and load at the current output.
‣
If a current output is not required, then switch off the current output via the
configuration.
‣
Connect current output to load.
