NOTICE
This guide provides basic guidelines for Rosemount 520 Level Transmitters. It does not provide instructions
for configuration, diagnostics, maintenance, service, troubleshooting, or Intrinsically safe installations. Refer
to the Rosemount 520 Reference Manual for more information.This manual is also available electronically on
EmersonProcess.com/Rosemount.
Explosions could result in death or serious injury.
Installation of this transmitter in hazardous areas must be in accordance with the appropriate local, national,
and international standards, codes, and practices. Review approvals section of the Rosemount 520 Reference
Manual for any restrictions associated with a safe installation.
Before connecting a HART®-based communicator in an explosive atmosphere, make sure the instruments in
the loop are installed in accordance with intrinsically safe or non-incentive field wiring practices.
Electrical shock can result in death or serious injury.
Avoid contract with the leads and the terminals. High voltage that may be present on leads can cause
electrical shock.

Quick Start Guide
1.0 System readiness
1.1 HART Communication
The Rosemount 520 utilizes the HART Communications Protocol. The most
notable advantage of employing HART Communications is that digital
information can be transmitted over legacy 4–20mA analog instrumentation
wiring. In addition to providing device diagnostics and process alerts, the ability
to communicate to the device remotely simplifies basic configuration,
calibration, and maintenance. A task-oriented, user optimized interface
eliminates errors and speeds routine maintenance tasks.
For the Rosemount 520, HART Protocol facilities two basic operation
configurations.
Point-to-point
In this configuration, digital signals are superimposed on the 4–20 mA loop
current. One process variable is sent on the 4–20 mA signal and other secondary
or calculated process variables can be transmitted digitally over the 4–20 mA
signal.
Multidrop
Multidrop refers to the connection of several transmitters to a single
communication transmission line. Communication between the host and the
transmitters occurs digitally with the analog output of the transmitters
deactivated. With HART Revision 7, up to 63 transmitters can be connected on a
single twisted pair of wires. Multidrop installation requires consideration of the
update rate necessary from each transmitter, the combination of transmitter
models, and the length of the transmission line.
For more information, reference “Connect wiring and power up” on page 13.
1.2 Configuration tools
There are several tools that can be used to configure the Rosemount 520.
The Field Communicator is a portable, handheld device used to configure field
devices or perform diagnostics for effective troubleshooting in the field without
having to use a laptop. The Field Communicator supports all HART devices and is
available in an intrinsically safe version.
HART modems allow AMS™ Device Manager to communicate with HART devices
using a PC serial port, PC USB port, or Bluetooth® connectivity. Serial and USB
HART modems attach directly to a PC or laptop computer and do not require an
external power supply. Bluetooth HART modems require a self-contained power
source (AAA batteries) as well as a Bluetooth-ready workstation PC.
HART modems also allow the Rosemount Transmitter Interface Software (RTIS)
to communicate with HART devices using a PC USB or serial port. The RTIS is a
PC-based application that performs configuration and maintenance functions for
the Rosemount 520 Transmitter. The Rosemount 520 is not shipped with the
RTIS; the RTIS can be ordered separately.

1.3 Confirm HART Revision capability
If using HART-based control or asset management systems, confirm the HART
capability of those systems prior to transmitter installation. Not all systems are
capable of communicating with HART Revision 7 Protocol.
1.4 Confirm correct device driver
Verify the latest device driver (DD/DTM™) is loaded on your system to ensure
proper communication.
Download the latest DD/DTM at EmersonProcess.com.
2.0 Handling
Proper handling of the Rosemount 520 is critical. To avoid damaging the
transmitter, avoid doing the following:
 Lifting by the cable if the transmitter is mounted with fittings
 Removing the protective diaphragm cap before installation
 Applying pressure to the diaphragm using fingers, tools, or sharp objects
 Using sharp objects to clean the diaphragm
 Submerging or blocking the vent tube
 Bending the cable within a radius of less than 90mm
3.0 Mount the transmitter
Note
All installation methods described in the following sections are grounded. If a different installation
method is used, the transmitter must be grounded to meet EMC and hazardous location
requirements.
3.1 Internal mounting
1. Secure the bracket to the tank wall.
2. Secure the transmitter by use of the provided spring. The spring is fitted into
the two holes in the bracket. The transmitter can be mounted and
dismounted without the use of tools.
3. Secure the transmitter cable to the tank wall.
Note
Emerson recommends protecting the cable by appropriate means to avoid the cable being
damaged from, for example, sloshing waves.
Emerson recommends installing the transmitter in locations with limited or no turbulence.
Emerson recommends avoiding this specific mounting method for service tanks due to challenges
associated with performing service and maintenance. Other mounting methods, such as pole
mounting, flexible rubber tube mounting and flexible PTFE tube mounting are recommended for
installation inside service tanks.

4.0 Connect wiring and power up
4.1 Signal cable
Shielded twisted pair cable should be used for best result. Use wire with minimum
diameter of 0.51 mm (24 AWG). To ensure the functionality of the digital
communication the following table shall be used to determine the maximum
signal cable length:
Table 4. Signal Cable Length
Transmitter cable length
Signal cable maximum length
0 m < ⫻ ≤ 25 m
825 m
25 m < ⫻ ≤ 50 m
770 m
50 m < ⫻ ≤ 100 m
660 m
100 m < ⫻ ≤ 200 m
440 m
200 m < ⫻ ≤ 300 m
220 m
Note
 The calculated signal cable lengths are based on a conventionally constructed
cable with a capacitance equal to or less than 200 pF/m.
 Maximum allowed transmitter cable length for installation in hazardous area is
75 m. Maximum allowed total cable length, transmitter cable plus signal
cable, must be determined by IS loop calculations.
4.2 Transmitter cable
The vent tube must be directed to an area with atmospheric pressure. If the
transmitter cable terminates in an area with overpressure or negative pressure
relative to the atmospheric pressure in the tank, the vent tube must be directed
to an area with atmospheric pressure equal to the pressure inside the tank.
4.3 Power supply
The power supply and load limitations are described in Figure 8 below. The total
resistance load is the sum of the resistance of the signal cable and the load
resistance of the controller, indicator, and related equipment. Note that the
resistance of intrinsic safety barriers, if used, must be included.

5.0 Verify transmitter configuration (optional)
Transmitters are shipped from Emerson fully configured per request or by the
standard factory default configuration. The configuration can be verified using
any HART capable configuration tool. Configuration instructions for the Field
Communicator are included in this step. See Rosemount 520 Reference Manual
for configuration instructions using AMS Device Manager or the Rosemount
Transmitter Interface Software (RTIS).
5.1 Verify configuration using the Field Communicator
A Rosemount 520 Device Driver (DD) must be installed on the Field
Communicator to verify configuration. Emerson recommends installing the latest
DD to access the complete functionality. Visit EmersonProcess.com for more
information.
Fast Key sequences for the latest DD are shown below in Table 6. A check ()
indicates the basic configuration parameters. At minimum, these parameters
should be verified as part of configuration and startup.

6.0 Trim the transmitter (optional)
Devices are calibrated by the factory. Once installed, it is recommended to
perform a zero trim. A zero trim is a single-point adjustment to compensate for
mounting position. When performing a zero trim, ensure the vent tube is vented
to atmospheric pressure.
6.1 Zero trim using the Field Communicator
1. Connect the Field Communicator
(see “Connect wiring and power up” on page 13 for instructions).
2. At the main menu, input the 3, 4, 1, 3 Fast Key sequence.
3. Follow the commands to perform a zero trim.
