1.
hardware failure
2. memory failure
3. Fail-safe LOE timer expired– possible
causes: faulty installation, antenna material
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.
S: 53 * Configuration lost: one or more parameter
settings have been lost. This may occur after a
firmware upgrade causes user parameters to
be reset.
