1 Safety messages

WARNING

Failure to follow safe installation and servicing guidelines could result in
death or serious injury.

• Only qualified personnel should install the equipment.

• Use the equipment only as specified in this guide and the Reference

Manual. Refer to the Rosemount 5300 Level Transmitter Reference

Manual for more instruction.

Explosions could result in death or serious injury.

• Installation of device in an explosive environment must be in accordance

with appropriate local, national, and international standards, codes, and
practices.

• Ensure device is installed in accordance with intrinsically safe or non-

incendive field practices.

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.

• Ensure 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.

Process leaks could result in death or serious injury.

• Handle the transmitter carefully.

• If the process seal is damaged, gas could escape from the tank when

removing the transmitter head from the probe.

WARNING

Physical access

Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or
unintentional and needs to be protected against.

Physical security is an important part of any security program and
fundamental to protecting your system. Restrict physical access by
unauthorized personnel to protect end users’ assets. This is true for all
systems used within the facility.

2 About the cold temperature option code BR5

The Rosemount 5300 Level Transmitter with option code BR5 has been
factory configured for best performance in cold ambient temperature, down
to -67 °F (-55 °C).

This document describes option code BR5 factory settings and required
commissioning, for Rosemount 5300 with single probes.

For general Rosemount 5300 information, refer to the Rosemount 5300
Level Transmitter Product Data Sheet.

High Level Supervision (HLS)

Specific instructions for HLS in combination with option code BR5 are
described in this document. For general HLS information and instructions,
refer to the High Level Supervision Manual Supplement.

2.1 Required commissioning

The Trim Near Zone function shall be performed during commissioning, see
section Perform Trim Near Zone for further instructions.

2.2 Specification

Rosemount 5300 option code BR5 specification is listed in Table 2-1.

2.3 Start-up sequence

The Rosemount 5300 start-up time is normally <40 s. However for devices
with option code BR5 at temperatures below -40 °F (-40 °C), the start-up
sequence is delayed for five minutes with an undefined current value. Refer
to Figure 2-1 and Figure 2-2.

Perform Trim Near Zone using Rosemount Radar Master

Prerequisites

Before performing the Trim Near Zone, ensure that:

• There is product in the tank.

• The product level is below the Near Zone region (0-3.3 ft (0-1 m) below

the Upper Reference Point).

Procedure

1. Select Setup → Advanced.

2. Select the Near Zone tab.

3. Select Trim Near Zone and follow the on-screen instructions.

4. When near zone trimming is complete, restart the device.
a) Select Tools → Restart Device.

3.2 Perform Trim Near Zone using AMS or a handheld communicator

Prerequisites

Before performing the Trim Near Zone, ensure that:

• There is product in the tank.

• The product level is below the Near Zone region (0-3.3 ft (0-1 m) below

the Upper Reference Point).

Procedure

1. HART®: Select Overview → Echo Tuning.

FOUNDATION™ Fieldbus: Configure → Manual Setup → Avanced.

2. Select Near Zone → Trim Near Zone and follow the instructions.

3. When near zone trimming is complete, restart the device.
a) HART: Select Service Tools → Maintenance.

4 Surface threshold for option code BR5

The surface threshold is pre-configured at factory for transmitters with
option code BR5. It is typically not necessary to make manual adjustments to
the pre-configured surface threshold. Manual adjustments are necessary in
the following cases:

• Configuration in transmitter has been reset to factory settings

• Threshold has been overwritten by other actions

4.1 Adjust surface threshold using Rosemount Radar Master

Prerequisites

When adjusting the surface threshold manually, the Trim Near Zone
function shall also be performed.

Note

If the adjusted threshold is set lower than the factory settings, Trim Near
Zone must be performed within 72 °F (40 °C) of the expected ambient
operating temperature. For factory settings, see Surface threshold for

option code BR5 - factory settings.

Procedure

1. Select Setup → Echo Curve.

2. Drag and drop the Amplitude Threshold Curve (ATC) points to adjust
the surface threshold according to factory settings.

3. Click Store to save ATC to device.

Postrequisites

Perform Trim Near Zone (if not already done).

Prerequisites

When adjusting the surface threshold manually, the Trim Near Zone
function shall also be performed.

Note

If the adjusted threshold is set lower than the factory settings, Trim Near
Zone must be performed within 72 °F (40 °C) of the expected ambient
operating temperature. For factory settings, see Surface threshold for

option code BR5 in combination with HLS - factory settings.

Procedure

1. Select Setup → Echo Curve.

2. Drag and drop the Amplitude Threshold Curve (ATC) points to adjust
the surface threshold according to factory settings.

3. Click Store to save ATC to device.
