BeforestartingHARTcommunication
Check the following before starting communication.
•  Tthe wiring connections with this device are completed.
•  The input signal (4–20 mA DC) from the controller (constant current source) is correctly 
applied.
• 
  Handling Precautions:
-   If there is no input signal from the controller, connect the constant 
current source to the input signal terminal (IN). The lines from the 
controller must be removed in this case.
-   Please download the latest DD (Device Description) when using the 
HART communication tool.
