Electrical Wiring

1. Refer 375/475 field communicator manual from EMERSON for 375/475 field communicator
usage.
2. Refer Operation manual "SMART POSITIONER (No.:DIG-31900-OM002)" for electric
wiring method of the positioner.
■Electric Wiring for Positioner
Refer Operation manual "SMART POSITIONER (No.:DIG-31900-OM002)".

■375/475 Field Communicator Wiring

375/475 field communicator is wired according to fig. 3. 375/475 field communicator is connected
parallel to the positioner input current line.

maintenance.

Before Starting HART Communication

■Positioner's LCD Display During HART Communication

During HART communication of the positioner, communication
display on the positioner's LCD flashes (See fig.4). Correctness
of HART communication can be checked by checking LCD.
1: Even during 375/475 field communicator, the communication display
does not flash if commands from 375/475 field communicator and
the data from the positioner are not sent.
