Choice of breakdown information (in accordance with NAMUR
Recommendation NE 43) if the tube does not oscillate correctly or a value
is outside the density range:
• Minimum value: 2 mA
• Maximum value: 22 mA (not Namur: 23 mA)
• Actual value
• Last valid value
Breakdown of power supply
Breakdown information during disconnection of power supply:

Plain text display
Error message on operational display.
Status information
Error message with status information
Status information
Status indicated by two light emitting diodes (in accordance with NAMUR
Recommendation NE 43).
The light emitting diodes indicate the following information:
• Supply voltage active
• Data transmission active
• Device alarm/error has occurred
Power connection
DC 8 to 30 V, the power unit must be tested to ensure it meets safety
requirements (e.g. PELV, SELV)
USB port (optional)
DC 5 V
Maximum power consumption
400 mW
