Cause
Corrective measure
S140
Warning
0x180F
Sensor signal outside
of permitted ranges
Overpressure or low pressure
present
Operate device in the specified measuring
range
S140
Warning
0x180F
Sensor signal outside
of permitted ranges
Sensor defective
Replace device
F270
1) 2)
Problem
0x1800
Overpressure/low
pressure
Overpressure or low pressure
present
• Check the process pressure
• Check sensor range
• Restart device
F270
1) 2)
Problem
0x1800
Defect in electronics/
sensor
Defect in electronics/sensor
Replace device
C431
3)
Warning
0x1805
Invalid position
adjustment (Current
output)
The adjustment performed would
cause the sensor nominal range to
be exceeded or undershot.
Position adju parameter of the
current output must be within the sensor
nominal range
• Check position adjustment (see
Zero
point configuration (ZRO)
parameter)
• Check measuring range (see
Value for 20
mA (STU)
and
Value for 4 mA (STL)
parameters)
C432
Warning
0x1806
Invalid position
adjustment (Switching
output)
The adjustment performed causes
the switch points to be outside the
sensor nominal range.
Position adju parameter of the
hysteresis and window function must be
within the sensor nominal range
• Check position adjustment (see
Zero
point configuration (ZRO)
parameter)
• Check the switch point, switchback point
for hysteresis and window function
F437
Problem
0x1810
Incompatible
configuration
Invalid device configuration
• Restart device
• Reset device
• Replace device
C469
Problem
0x1803
Switch points output
violated
Switch point ≤ switchback point
Check switch points at output
C485
Warning
0x8C01
4)
Simulation active
During simulation of the switch
output or current output, the
device issues a warning message.
Switch off simulation.
S510
Problem
0x1802
Turn down violated
A change in the span results in a
violation of the turn down (max.
TD 5:1)
Values for calibration (lower range
value and upper range value) are
too close together
• Operate device in the specified measuring
range
• Check the measuring range
S803
Problem
0x1804
Current loop
Impedance of load resistance at
analog output is too high
• Check the cabling and load at the current
output.
• If the current output is not required,
switch the current output off via the
configuration.
S803
Problem
0x1804
Current output not
connected
Current output not connected
• Connect current output with load.
• If the current output is not required,
switch the current output off via the
configuration.
F804
Problem
-
Overload at switch
output
Load current > 250 mA
Increase load resistance at switch output
