Errors and warnings

If an error in the device occurs, the colour of the status LED changes from green to red and the
background illumination of the digital display changes from blue to red. The measured value and
message are displayed alternately. The display shows:
• E-code for errors. In the event of error messages, the measured value is uncertain.
• W-code for warnings. In the event of a warning, the measured value is reliable.

Explanation
Device configuration defective
Error in measurement or
pressure out of specification
Power supply outside specification
Memory error
Power is only supplied to the device via the
communication interface (measurement is
deactivated)
Switching contact 1 is not open although it
should be
Switching contact 2 is not open although it
should be
VCC (controller voltage) is out of working area
Output current can no longer be generated (only
for 4 to 20 mA output, e.g. load at analog output
too high or open analog output)
Output current drifts too much (±0.5 mA)
Explanation
Simulation active
Pressure outside the sensor range
Device starts
Configuration modified (warning code will be
displayed for 15 s approx.)
