Emerson Rosemount 5300 Series - Introduction

WARNING
Failure to follow safe installation and servicing guidelines could result in death or serious
injury.
• Make sure the transmitter is installed by qualified personnel and in accordance with
applicable code of practice.
• Use the equipment only as specified in this manual. Failure to do so may impair the
protection provided by the equipment.
• Do not perform any services other than those contained in this manual unless you are
qualified.
Explosions could result in death or serious injury.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• To prevent ignition of flammable or combustible atmospheres, disconnect power
before servicing.
• Before connecting a handheld communicator in an explosive atmosphere, ensure the
instruments in the loop are installed in accordance with intrinsically safe or non-
incendive field wiring practices.
Process leaks could result in death or serious injury.
• To avoid process leaks, only use the O-ring designed to seal with the corresponding
flange adapter.
Electrical shock could cause death or serious injury.
• Avoid contact with the leads and terminals. High voltage that may be present on leads
can cause electrical shock.
• Make sure the mains power to the transmitter is off and the lines to any other external
power source are disconnected or not powered while wiring the transmitter.
Probes with non-conducting surfaces
• Probes covered with plastic and/or with plastic discs may generate an ignition-capable
level of electrostatic charge under certain extreme conditions. Therefore, when the
probe is used in a potentially explosive atmosphere, appropriate measures must be
taken to prevent electrostatic discharge.
K.2 Introduction
The Rosemount 5300 Level Transmitter is a Modbus compatible measurement device that
supports communication with a Remote Terminal Unit (RTU) using a subset of read, write,
and diagnostic commands used by most Modbus compatible host controllers. The
transmitters also support communication through Levelmaster and Modbus
®
ASCII
protocols.
The HART to Modbus Converter (HMC) module is located inside the Rosemount 5300
Level Transmitter enclosure and provides power to and communicates with the
transmitter through a HART
®
interface.
