What to do if the fluid temperature is outside the specification for Endress+Hauser Flowphant T DTT31?
If the fluid temperature exceeds 85 °C, which is outside the specification, check the fluid temperature and adapt it to the specification if necessary.
What to do if the output current cannot be generated on Endress+Hauser Flowphant T DTT31 Switch?
If the output current cannot be generated (only for 4 to 20 mA output, e.g. load at analog output too high or open analog output), check the load and switch off the analog output.
What to do for short-circuit and overload at output 1 on Endress+Hauser Flowphant T DTT31?
In case of a short-circuit or overload at output 1, check the output wiring.
What to do for short-circuit and overload at output 2 on Endress+Hauser Switch?
In case of a short-circuit or overload at output 2, check the output wiring.
What to do if the power supply is outside specification on Endress+Hauser Flowphant T DTT31?
If the power supply is outside the specification, check the operating voltage.
What to do if the measured flow rate is outside the range on Endress+Hauser Switch?
If the measured flow rate is outside the range between set Low and High Flow (< -10% or > 110%), set High and Low Flow again, reset device to factory setting where necessary (PRES function).
What if High Flow or Low Flow values cannot be determined on Endress+Hauser Flowphant T DTT31?
If values for High Flow (HIF) or Low Flow (LOWF) could not be determined with certainty, set High and Low Flow again, keeping the flow velocity constant.
What to do if there is an error in measurement or medium temperature outside measurable range for Endress+Hauser Switch?
Check the medium temperature and, if necessary, return the Endress+Hauser Switch device.
Why Endress+Hauser Switch displays error E019?
Error E019 on your Endress+Hauser Switch indicates that the power supply is outside of the specified range. To resolve this, check the operating voltage to ensure it meets the device's requirements.
What to do if Endress+Hauser Flowphant T DTT31 shows error E042?
If your Endress+Hauser Switch displays error E042, it means the output current cannot be generated. This usually occurs with 4 to 20 mA outputs due to the load at the analog output being too high or the analog output being open. You should check the load and switch off the analog output to resolve this issue.
