Safety messages

This guide provides basic guidelines for this product. It does not provide instructions for configuration,
diagnostics, maintenance, service, or troubleshooting. Procedures and instructions in this section may
require special precautions to ensure the safety of personnel performing the operation.

CAUTION

The products described in this document are NOT designed for nuclear-qualified applications. Using
non-nuclear qualified products in applications that require nuclear-qualified hardware or products may
cause inaccurate readings. For information on Rosemount nuclear-qualified products, contact your
local Emerson Sales Representative.

WARNING

Explosions

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.

Process leaks

Process leaks may cause harm or result in death.

Install and tighten process connectors before applying pressure.

Electrical shock

Electrical shock can result in death or serious injury.

Avoid contact with the leads and terminals. High voltage that may be present on leads can cause
electrical shock.

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

September 2020 Quick Start Guide

1 Introduction

The Rosemount™ 550PT is a pressure transmitter designed for use with the
Rosemount 551 Single-Use Process Connector in single-use pharmaceutical
manufacturing. The Rosemount 551 provides a sterile barrier to contain the
process and transfer pressure to the transmitter which converts the reading
into a 4-20 mA output signal.

1.1 About this guide

This guide provides basic guidelines for the Rosemount 550PT Transmitter.
It does not provide instructions for configuration, diagnostics, maintenance,
or service. This guide is also available electronically at Emerson.com/

Rosemount.

Quick Start Guide 3

Quick Start Guide September 2020

2 Installation

2.1 Insert the Rosemount 551 into the process equipment

Procedure

1. CAUTION

Do not push directly on the isolating diaphragm during assembly as
this can damage and possibly rupture the barrier.
Do not use sharp tools to complete this step.

Insert the Rosemount 551 into a ½-in. port or tubing by pressing on
the protective cap.

2. Secure with a cable tie.

2.2 Wire the transmitter

Procedure

1. Ensure a tight connection between the cable and 6-pin connector.
There will be an audible click when cable is completely connected.

The Emerson supplied cable must be used to ensure proper electrical
connection and prevent damage to the transmitter.

2. Connect the two wires to a data acquisition system that supplies 24
Vdc of power.

Note

Transmitter requires between 20-28 Vdc under normal operating
conditions. A loop impedance of 250 Ohms is recommended.

Connect the transmitter

Prerequisites

Ensure no external pressure is applied to the single-use connector.

Procedure

1. Remove the protective cap from the single-use process connector.

2. Place the flange of the single-use process connector into the
transmitter and attach using a ½ / ¾-in Tri Clamp (Rosemount part #
00550-3100-0001).

3. Tighten the Tri Clamp until the connection is finger-tight and feels
secure.

September 2020 Quick Start Guide

Note

Over-tightening can lead to degraded performance over time.

4. Orient the transmitter to the position in which it will be used (see

Figure 4-3).

2.4 Set the transmitter zero point

Prerequisites

Ensure the transmitter is powered on and no pressure (other than the
desired zero point) is applied to the sensor.

Procedure

1. Place magnet over the circle on the transmitter labeled “Place
magnet here” and hold for one second.

2. As soon as the LED blinks (about one second), remove the magnet.
The zero point is saved.

Need help?

If more than 4 psig is applied to the transmitter during this process,
this step will fail (indicated by three brief LED flashes). If this happens,
ensure minimal pressure is being applied to the transmitter and
repeat Step 1.

3 Troubleshooting

3.1 Transmitter will not zero despite having no pressure applied

CAUTION

Ensure no pressure is applied to single-use process connector before
continuing.

Solution: Factory reset required

Recommended actions

1. Disconnect the process connector from the transmitter.

2. Attempt a zero (see Set the transmitter zero point) and, if the
zero was successful with no process connector attached,
reattach the transmitter with the clamp.

3. Perform the zero function again with the clamp applied.

4. If the zero procedure fails, perform a factory reset by holding a
magnet on the magnet point for four seconds.

If the factory reset is successful, the LED will illuminate for four
seconds before returning to factory calibration.

If this procedure fails, contact your local Emerson
representative.
