Connection to HART Protocol (4-Wire)
Note: For providing of correct work of HART interface, a 250 Ohm resistor is required. In the case of low resistance of the controller
4-20 mA, the resistor can be installed in the controller input instead of IR3 output.
1.
To power the IR3, connect the power cable from the 18-32 VDC power supply to X4 terminal (+24V & COM)
2.
Connect a cable to X4 terminal (-4/20). This cable shall then connect to one side of the Field communicator terminal
3.
Connect a cable to X3 terminal (+4/20) that is in series with a 250 Ohm resistor. This cable shall then connect to another side of
the Field communicator terminal
4.
The connection shall form a parallel circuit with the 250 Ohm resistor
5.
Power up the IR3 and Field communicator.
6.
Follow the HART menu to navigate to the corresponding function.
