7.7.3 Information codes in display and in serial communication
Display
The info code types which are related to the meter’s different sensors t1, t2 and V1 will in case of error influence the
display readings, to which they are tied. In connection with current values for temperatures, flow and power three
horizontal lines will appear in the display, and the energy registers, in which counting is dependent on the sensor
function, will not be accumulated. See paragraphs 6 and 7.1.3 for further information on sensor errors.
Temperature sensor error
The error can be due to the sensor being disconnected or short-circuited. An erroneous ΔΘ alone will not be
considered a temperature sensor error.
In case of an error in one or more temperature sensors (t1 and t2), the value of the serial communication of the
sensor in question will be 0,00 °C (lowest valid temperature) or 185,00 °C (highest valid temperature) respectively,
depending on the measurement being below range (sensor short-circuited) or above range (sensor disconnected).
The display reading of the sensor in question shows lines in the three digits to the far right in the display,
independent of the cause of the error. Decimal points are not included.
The display readings of ΔΘ and current power will also show three lines for errors in one or more temperature
sensors. In serial communication the power value will be 0,0 kW.
Flow sensor error
The error can be due to air in the flow sensor (V1) or due to the fact that it has been mounted with the wrong flow
direction. V1 > q
s
does not prevent the meter from measuring, and is thus not considered an error in this connection.
In case of flow sensor error the flow value will in serial communication be 0 l/h. The display reading of current flow
shows lines in the three digits to the far right in the display. Decimal points are not included.
The display reading of current power will also show three lines for flow sensor error. In serial communication the
power value will be 0,0 kW.
