The temperature of the thermal measuring element is outside the permissible limits.
Measuring medium temperature outside of the set alarm threshold or permissible limit
values.
• Check parameterization, see menu Menu: Process Alarm on page 118
• Check process conditions, see chapter Process conditions on page 30
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.
Check ambient temperature (see Ambient conditions on page 27)
•
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.
Communication error to plug-in card.
• Check that the plug-in card is installed correctly.
• Replace plug-in card if necessary.
• Contact ABB Service.
The pulse rate or the frequency at the pulse output 41 / 42 is outside the permissible limits.
• Check configuration of the parameters for the pulse output.
The pulse rate or the frequency at the pulse output 51 / 52 is outside the permissible limits.
• Check configuration of the parameters for the pulse output.
