11.2 Error messages
Low Voltage
If the supply voltage is less than 11V, the warning message
„Low Voltage“
is displayed.
This means that the sensor can no longer work / measure correctly and thus there are none
measured values for flow, consumption and speed are available.
Heater Error
The error message
„Heater Error“
occurs in case of failure of the heating sensor.
Internal Error
In the case of this message
„Internal Error“
, the sensor has an internal read error on e.g. EEProm, AD converter
etc. detected.
Temp out of Range
At media temperatures outside the specified temperature range, the status message
„Temp out of Range“
occurs.
This temperature overshoot leads to incorrect measurement values (outside the sensor specification).
Low Voltage 4-20mA
For sensors with a galvanically isolated 4-20mA output, a min. Supply voltage of 17.5V is required. If this value is
undershot, the error message
„Low Voltage 4-20mA“
is displayed.
