Rosemount 8712 / 8700 Series

Environmental Considerations

To ensure maximum transmitter life, avoid excessive heat and vibration. Typical problem areas include:

Warm-climate installations in direct sunlight

Outdoor installations in cold climates

Remote mounted transmitters may be installed in the control room to protect the electronics from the harsh environment and provide easy access for configuration or service.

Remotely mounted Rosemount 8712 transmitters require external power so there must be access to a suitable power source.

Installation Procedures

Rosemount 8712 installation includes both detailed mechanical and electrical installation procedures.

Mount the Transmitter

At a remote site the transmitter may be mounted on a pipe up to two inches in diameter or against a flat surface.

Pipe Mounting

To mount the transmitter on a pipe:

1.Attach the mounting plate to the pipe using the mounting hardware.

2.Attach the 8712 to the mounting plate using the mounting screws.

Identify Options and Configurations

The standard application of the 8712 includes a 4–20 mA output and control of the sensor coils and electrodes. Other applications may require one or more of the following configurations or options:

Multidrop Communications

Digital Output

Digital Input

Pulse Output

Additional options may apply. Be sure to identify those options and configurations that apply to your situation, and keep a list of them nearby for consideration during the installation and configuration procedures.

Hardware Jumpers/Switches

The 8712 electronics board is equipped with three user-selectable hardware switches. These switches set the Failure Alarm Mode, Internal/External Analog Power, and Transmitter Security. The standard configuration for these switches when shipped from the factory are as follows:

Failure Alarm Mode:

HIGH

Internal/External Analog Power:

INTERNAL

Transmitter Security:

OFF

Changing Hardware Switch Settings

In most cases, it is not necessary to change the setting of the hardware switches. If you need to change the switch settings, complete the steps outlined in the manual.
