behavior EventCode Event text 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

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
