CONFIGURATION USING HART

MPORTANT

The digital HART

ommunication is superimposed on the

4-20 mA loop and requires a min. load resistance of 250 Ω and a max load

resistance of 450 Ω.

CONNECTIONS

CHECK HART

Connection of your Hart communicator:

• at power terminals (+) and (-) in wiring compartment

• at ﬁrst junction box between unit and control room.

Before starting the HART

conﬁguration procedure – check if your HART

commu-

icator is equipped with the proper Jupiter Device Descriptors (DD’s).

I/O start up the communicator

Select NO: go ofﬂine

Select 4: utility

Select 5: simulation

Check manufacturer: Magnetrol
