10.2 Fault codes
Code/ Meaning
Icon
S: 30 EEPROM corrupt.
S: 31 * Flash error.
S: 33 * Factory calibration for the internal temperature sensor
has been lost.
S: 34 * Factory calibration for the device has been lost.
S: 48 * User configuration is invalid. One or more of parameters:
Low Calibration Point, High Calibration Point, Volume
breakpoints, and/or Auto False-Echo Suppression, are
set to invalid values.
S: 52 Fail-safe is activated. Possible causes:
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.
S: 54 * Fault occurs when the PV exceeds the user configured
min./max. range for mA output.
S: 66 Device error.
to NOTE: Fault text and icons appear only on the local
S:83 display.

Corrective Action
Reset power. If fault persists, contact your local
Siemens representative.
Repair required: contact your local Siemens repre-
sentative.
Repair required: contact your local Siemens repre-
sentative.
Repair required: contact your local Siemens repre-
sentative.
Reconfigure the unit.
•
Ensure the difference between High Calibration
•
Point and Low Calibration Point is not less than
or equal to zero; do a Master Reset.
For 3:
•
Correct configuration; ensure installation is cor-
rect;
no antenna buildup;
•
adjust process conditions to minimize foam-
•
ing/other adverse conditions;
correct calibration range.
•
If fault persists, or for 1 and 2, contact your local
Siemens representative.
Adjust process to fall within limits of min./max. mA
values or adjust limits of mA if possible.
Repair required: contact your local Siemens repre-
sentative.
