Fail-safe is activated. Possible causes:
1) hardware failure
2) memory failure
3) Fail-safe LOE timer expired– possible
causes: faulty installation, antenna mate-
rial buildup, foaming/other adverse process
conditions, invalid calibration range.
For 3):
• Correct configuration; ensure installation
is correct;
• no antenna buildup;
• adjust process conditions to minimize
foaming/other adverse conditions;
• correct calibration range.
If fault persists, or for 1) and 2), contact
your local Siemens representative.

Configuration lost: one or more parameter
settings have been lost. This may occur
after a firmware upgrade causes user
parameters to be reset.
Restore user parameters using SIMATIC
PDM.
