Transmitter Installation - Emerson Rosemount 8700M Quick Start Manual

August 2015
Step 1: Transmitter installation
Installation of the Rosemount Magnetic Flowmeter includes both detailed
mechanical and electrical installation procedures.
Before installing the Rosemount 8732EM Magnetic Flowmeter Transmitter, there
are several pre-installation steps that should be completed to make the
installation process easier:
Identify the options and configurations that apply to your application

Set the hardware switches if necessary

Consider mechanical, electrical, and environmental requirements

1.1 Identify options and configurations
The typical installation of the 8732EM includes a device power connection, a
Modbus RS-485 output connection, and sensor coil and electrode connections.
Other applications may require one or more of the following configurations or
options:
Pulse Output

Discrete Input/Discrete Output

Hardware switches
The 8732EM electronics stack is equipped with user-selectable hardware
switches. These switches set the Internal/External Pulse Power and Transmitter
Security. The factory default settings for these switches is as follows:
Table 1. Hardware Switch Default Settings

Transmitter Security
In most cases, it will not be necessary to change the hardware switch settings. If
the settings need to be changed, follow the steps outlined under "Changing
hardware switch settings" in Reference Manual 00809-0400-4444.
Note
To prevent switch damage, use a non-metallic tool to move switch positions.
Be sure to identify any additional options and configurations that apply to the
installation. Keep a list of these options for consideration during the installation
and configuration procedures.
1.2 Mechanical considerations
The mounting site for the Rosemount 8732EM transmitter should provide
enough room for secure mounting, easy access to conduit entries, full opening of
the transmitter covers, and easy readability of the LOI screen, if equipped.
For remote mount transmitter (8732EMRxxx) installations, a mounting bracket is
provided for use on a 2-inch pipe or a flat surface (see
