OVERVIEW This section contains information on commissioning and tasks that should be
performed on the bench prior to installation. This section contains 3144P
HART configuration only. 375 Field Communicator and AMS instructions are
given to perform configuration functions. For additional information, refer to
the HART Communication Reference Manual (document number
00809-0100-4276). AMS help can be found in the AMS on-line guides within
the AMS system.
SAFETY MESSAGES Instructions and procedures 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 ( ). Please
refer to the following safety messages before performing an operation
preceded by this symbol.
Explosions may result in death or serious injury.
• Do not remove the instrument cover in explosive atmospheres when the circuit is
live.
• Before connecting a 375 Field Communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
• Both covers must be fully engaged to meet explosion–proof requirements.
Electrical shock could cause death or serious injury. If the sensor is installed in a
high-voltage environment and a fault or installation error occurs, high voltage may be
present on transmitter leads and terminals.
• Use extreme caution when making contact with the leads and terminals.
