HART/Bell202 connections are made through terminals 21 and 22. See Figure 3-9.

Figure 3-9 HART/Bell202 connections to Model 1500 or 2500

CAUTION

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 interface 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 interface to the transmitter’s primary

mA output loop.
