Description
External switch-off active via digital input.
• Check status of digital input.
• Check parameterization.
External switch-off active via digital input.
• Check status of digital input.
• Check parameterization.
Reset of one or more counters.
• Check status of digital input.
• Check parameterization.
Simulation mode is active.
• Deactivate simulation mode in the 'Diagnostics / ...Simulation Mode' menu.
The alarm simulation is active.
• Deactivate alarm simulation in the 'Diagnostics / ...Alarm Simulation' menu.
Current loop error current output 31 / 32.
• Check current loop current output 31 / 32 (short-circuit / interruption).
• Check load current output 31 / 32.
• Check the power supply (voltage) of the transmitter.
Gas bubbles in the measuring tube.
• Reduce gas content in the measuring medium.
• Deactivate error message by setting the parameter 'Driver Output Max' in the 'Process Alarm /
...Alarm Limits' menu to '0'.
Empty measuring tube. Gas bubbles in the measuring tube.
• Reduce gas content in the measuring medium.
• Make sure that the meter tube is always completely full.
• Deactivate error message by setting the parameter 'Density Low Check' in the 'Process Alarm /
...Alarm Limits' menu to '0'.
Density has been set to 1 g/cm 3 by the transmitter due to an error message.
• Contact ABB Service.
Ambient or measuring medium temperature is too high.
• Check ambient or measuring medium temperature.
The sensor amplitude is below or above the parameterized limit values 'Sensor Signal Min' and
'Sensor Signal Time'.
Multi-phases measuring medium. Viscosity of the measuring medium is too high.
• Check the settings of the parameters in the 'Process Alarm / ...Alarm Limits' menu and adjust if
necessary.
Current output 31 / 32 overshot. The flow has exceeded the set upper measuring range value.
• Check the upper range value Qv Max, Qm Max in the 'Device Setup / ...Sensor' menu and correct if
necessary.
Current output V1 / V2, V3 / V4 (plug-in card) overshot. The flow has exceeded the set upper
measuring range value.
• Check the upper range value Qv Max, Qm Max in the 'Device Setup / ...Sensor' menu and correct if
necessary.
