Commissioning with a
HART-Based
Communicator
Before putting the Rosemount 1151 Smart Pressure Transmitter into
operation, commission the instrument using a HART-based communicator.
To commission on the bench, connect a 17 to 45 V dc power supply and a
current meter. Make connections as shown in Figure 3-2. The power supplied
to the transmitter should not drop below the transmitter lift-off voltage. If the
transmitter is being configured when the power drops below the lift-off voltage,
the configuration information may not be interpreted correctly by the
transmitter.
NOTE
To enable communication, a resistance of at least 250 Ω must be present
between the communicator loop connection and the power supply.
WIRING DIAGRAMS
Bench Hook-up After the bench equipment is connected as shown in Figure 3-2, turn on the
HART-based communicator. The communicator will search for a
HART-compatible device and will indicate when the connection is made. If the
connection is not made, the communicator will indicate that no device was
found. If this occurs, refer to Section 5 Troubleshooting.
Figure 3-2. Bench Hook-up.
NOTE
An alternate location to connect an ammeter is on the set of terminals labeled
“TEST.” Connect the positive lead of the ammeter to the positive test terminal,
and the negative lead of the ammeter to the negative test terminal.
