Operating Instructions, 05/2019, A5E32337711-AC
S:52 Failsafe is activated. Possible causes: 1) hard-
ware failure; 2) memory failure; 3)Fault 48; 4)
failsafe timer expired– possible causes: faulty
installation, antenna buildup, foaming/ other
adverse process conditions, invalid calibration
range.
For 3) and 4) Correct configuration;
ensure installation is correct; no antenna
buildup; adjust process conditions to
minimize foaming/ other adverse condi-
tions; correct calibration range. If fault
persists, or for 1) and 2), contact your
local Siemens representative.
S:53 * Configuration lost: one or more parameter set-
tings have been lost. This may occur after a
firmware upgrade causes user parameters to be
reset.
Restore user parameters using
SIMATIC PDM.

Fault codes (firmware revision 1.05 or earlier)
Note
Some faults cause the device to go to Failsafe mode (Fault 34). These are indicated with an
asterisk (*).

User configuration has been lost. This may occur after a
software upgrade causes user parameters to be reset.
Use PDM to restore the user
parameters.
17
Standard device error category
1)
.
None
18
Standard device error category
1)
. This device has a single
power supply: if it fails, the device is non-operational, and
the fault will not be visible.
None
19
*
User configuration is invalid: device cannot operate. Pa-
rameters: Span, Volume breakpoints, and/or Auto False-
Echo Suppression, are set to invalid values. Note:
EEPROM Corrupted. If the parameter section of the
EEPROM is corrupt, the device will not have a valid con-
figuration, and will also show fault 39 and/ or fault 40, and
fault 34 (failsafe).
Check parameter settings
for configuration errors,
especially: Check Span is
not set to 0. Check the
breakpoints (only tested if
P050 is set to 9). Do a P999
reset.

There is a maintenance issue on the device. Standard
device error category
1)
; currently no maintenance faults
are activated.
None

, not supported.
None
25
The following problem has occurred in the electronics of
the device: DMA failure
Cycle the power: this may
temporarily solve the prob-
lem. Do not use the device
for measurement, but return
it to the factory as soon as
possible.

A mechanical failure in the device, such as a broken
cable.
None

Standard device error category
1).
None
28
Internal temperature of the device has been exceeded: it
is operating outside its temperature range.
Lower the ambient tempera-
ture enough to cool the
device.
