Safety messages

Procedures and instructions in this section may require special precautions to ensure the safety of the
personnel performing the operations. Information that raises potential safety issues is indicated by a
warning symbol (
by this symbol.
Explosions can result in death or serious injury.
Do not remove the transmitter covers in explosive environments when the circuit is live.

Transmitter covers must be fully engaged to meet explosion-proof requirements.

Before connecting a communicator in an explosive atmosphere, make sure the instruments in the

loop are installed in accordance with intrinsically safe or nonincendive field wiring practices.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause
electrical shock.

Commissioning on the bench

Commissioning consists of testing the transmitter and verifying transmitter configuration data.
Rosemount
Commissioning the transmitter on the bench before installation using a Field Communicator or AMS
Device Manager ensures all transmitter components are in working order.
Equipment required to commission on the bench includes a power supply, a milliamp meter, and a Field
Communicator or AMS Device Manager. Wire the equipment as shown in
transmitter terminal voltage is between 10.5–42.4 Vdc. To ensure successful communication, a
resistance of at least 250 ohms must be present between the Field Communicator loop connection and
the power supply. Connect the Field Communicator leads to the terminals labeled "PWR/COMM" on the
terminal block. (Connecting across the "TEST" terminals will prevent successful communication.)
Set all transmitter hardware adjustments during commissioning to avoid exposing the transmitter
electronics to the plant environment after installation. Refer to
When using a Field Communicator, any configuration changes made must be sent to the transmitter by
using the Send key. AMS Device Manager configuration changes are implemented when the Apply button
is selected.
2.3.1

Setting the loop to manual

Whenever sending or requesting data that would disrupt the loop or change the output of the
transmitter, set the process application loop to manual. The Field Communicator or AMS Device
Manager will prompt you to set the loop to manual when necessary. Acknowledging this prompt does
not set the loop to manual. The prompt is only a reminder; set the loop to manual as a separate
operation.
