Signal color Diagnostic message Description Measures
Communication error Restart the transmitter. In doing so, disconnect it from
the supply voltage for at least 30 s.
"No sensor connected" The sensor is not connected. Make sure that the sensor is connected to the
transmitter via the connecting cable.
Connecting cable or connections damaged. Check connecting cable and connections for damage.
Communication error Restart the transmitter. In doing so, disconnect it from
the supply voltage for at least 30 s.
"Temperature chip faulty" Sensor is defective. Contact Hauser Service.
"Sensor memory faulty" Sensor is defective. Contact Hauser Service.
"System is starting" Measuring device is initializing. Contact Hauser Service.
"Process disturbance" The value measured for the dispersion is
greater than 1. 1. Remove air bubbles and/or particles.
2. Take recommended mounting position into
consideration →  16.
3. If the error persists, contact Hauser
Service.
"Sensor configuration
failed" Missing calibration. Contact Hauser Service.
"System error" Communication error between internal
processors. 1. Restart the transmitter.
2. If the error persists, contact Hauser
Service.
12.4 Diagnostic information via the Modbus protocol
The diagnostic information can be indicated via status bits:
Bit Hexadecimal Diagnostic message Description Measures
0 0x00000001 No sensor The sensor is not connected. Make sure that the sensor is
connected to the
transmitter via the
connecting cable →  20.
1 0x00000002 No liquid No liquid present. Ensure that there is
sufficient liquid in the
sensor.
Sensor is fouled. Make sure the sensor is free
from dirt and deposit build-
up.
Air bubbles or particles in
the liquid. Remove air bubbles and/or
particles.
Communication error Restart the transmitter. In
doing so, disconnect it from
the supply voltage for at
least 30 s.
2 0x00000004 Temperature chip is faulty Sensor is defective. Contact Hauser
Service
3 0x00000008
4 0x00000010 Sensor memory faulty EEPROM in the sensor is
damaged. Contact Hauser
Service.
7 0x00000080 System starting Measuring device is
initializing. -
8 0x00000100 Process disturbance
detected The measured dispersion is
greater than the configured
switch point. • Remove air bubbles
and/or particles.
• Take recommended
mounting position into
consideration →  16.
