C.21 Acyclic extended diagnostics (general fault codes)
LCD display Meaning
S:0 The device was unable to get a measurement
within the Failsafe LOE Timer period. Possible
causes: faulty installation, antenna material
buildup, foaming/other adverse process con-
ditions, invalid calibration range.
S:2 Unable to collect profile because of a power
condition that is outside the operating range
of the device.
S:3 Device is nearing its lifetime limit according to
the value set in Maintenance Required Limit.
S:4 Device is nearing its lifetime limit according to
the value set in Maintenance Demanded
Limit.
S:6 Sensor is nearing its lifetime limit according to
the value set in Maintenance Required Limit.
S:7 Sensor is nearing its lifetime limit according to
the value set in Maintenance Demanded
Limit.
S:8 Service interval as defined in Maintenance
Required Limit has expired.
S:9 Service interval as defined in
Maintenance Demanded Limit
has expired.
S:10 Input parameters High Calibration Point and
Low Calibration Point are the same.
S:11 Internal temperature sensor failure.
S:12 * Internal temperature of the device has ex-
ceeded
specifications: it is operating outside its tem-
perature range.
S:14 Upper and lower input values (Process Value
Scale) for AIFB1 are the same.

Acyclic Extended Diagnostics /General Fault Codes
Corrective Action
Ensure installation details are correct.
•
Ensure no antenna material
•
buildup. Clean if necessary.
Adjust process conditions to minimize foam
•
or other adverse conditions.
Correct range calibration.
•
If fault persists, contact your local Siemens
•
representative.
Repair required. Contact your local Siemens
representative.
Replacement is recommended.

Perform service
Perform service.
Check calibration settings of device.
•
Ensure settings for High Calibration Point
•
and Low Calibration Point are different.
Repair required. Contact your local Siemens
representative.
Relocate device and/or lower process tem-
•
perature enough to cool device.
Inspect for heat-related damage and contact
•
your local Siemens representative if repair
is
required.
Fault code will persist until a manual reset is
•
performed using PDM or the LCD interface.
Check configuration for AIFB1.
•
Ensure that Upper Value and Lower Value
•
(Process Value Scale) are not the same.
