HART/Bell 202 connections

Connecting a HART device to the transmitter's primary mA output terminals
could cause transmitter output error.
If the primary mA output is being used for flow control, connecting a HART device
to the output loop could cause the transmitter's 4–20 mA output to change, which
would affect flow control devices.
Set control devices for manual operation before connecting a HART device to the
transmitter's primary mA output loop.
Follow the instructions below to make the connection.
1. Connect the HART interface to your PC's serial or USB port. Then connect the leads of the
HART interface to terminals 21 and 22 on the transmitter (see Figure 3-9).

2. Add 250–600 Ω resistance to the connection, as required.
3. Start ProLink II. Choose
