Note
Before installing the transmitter, confirm the correct device driver is loaded on the host
systems. See page 3 for System Readiness.
Quick Start Guide
February 2015
NOTICE
This guide provides basic guidelines for Rosemount 644 transmitters. It does not provide instructions for
configuration, diagnostics, maintenance, service, troubleshooting, Explosion-proof, Flameproof, or
intrinsically safe (I.S.) installations. Refer to the Rosemount 644 Reference Manual (document number
00809-0100-4728) for more instruction. This manual is also available electronically on
www.rosemount.com.
Explosions could result in death or serious injury.
Installation of this transmitter in an explosive environment must be in accordance with the appropriate
local, national, and international standards, codes, and practices. Please review the approvals section of the
644 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-incendive field wiring practices.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and the terminals. High voltage that may be present on leads can cause
electrical shock.

Conduit/cable entries
Unless marked, the conduit/cable entries in the transmitter housing use a 1/2-14 NPT thread form. Entries
marked “M20” are M20 ⫻ 1.5 thread form. On devices with multiple conduit entries, all entries will have
the same thread form. Only use plugs, adapters, glands, or conduit with a compatible thread form when
closing these entries.
 When installing in a Hazardous Location, use only appropriately listed or Ex certified plugs, adapters, or
glands in cable/conduit entries.

Confirm HART revision capability


If using HART based control or asset management systems, please confirm the
HART capability of those systems prior to transmitter installation. Not all
systems are capable of communicating with HART Revision 7 protocol. This
transmitter can be configured for either HART Revision 5 or 7.
For instructions on how to change the HART revision of your transmitter, see
“Verify configuration” on page 5.
Confirm correct device driver


Verify the latest Device Driver files are loaded on your systems to ensure
proper communications.

Transmitter installation
Step 1: Set the alarm switch
Set the 644 alarm switch before putting the device into operation.
Without an LCD display:
1. Set the loop to manual (if applicable) and disconnect the power.
2. Remove the housing cover.
3. Set the switch to the desired position (H indicates High, L indicates Low), then
reattach the housing cover.
4. Apply power and set the loop to automatic control.

Note
If using an LCD display, first remove the pink foam spacer located between the LCD and cover. The
spacer can be discarded. Next, remove the display by detaching it from the top of the device, set
the switch to the desired position and reattach the LCD display.

Quick Start Guide
Step 2: Verify configuration
Verify the configuration of the Rosemount 644 device upon receiving your
transmitter using any HART compliant configuration tool. See the Rosemount
644 Reference Manual (document number 00809-0200-4728) for configuration
instructions using AMS® Device Manager.
The 644 communicates using the Field Communicator (communication requires
a loop resistance between 250 and 1100 ohms). Do not operate when power is
below 12 Vdc at the transmitter terminal. See the 644 Reference Manual
(document number 00809-0200-4728) and Field Communicator Reference
Manual for more information.
Verify configuration with a Field Communicator
A Rosemount 644 DD (device descriptor) must be installed on the Field
Communicator to verify the configuration. Fast Key sequences for the latest DD
are shown in Table on page 6. For Fast Key sequences using legacy DD's, contact
your local Emerson Process Management representative.
Perform the following steps to determine if an upgrade is required.
1. Connect the sensor (see the wiring diagram located on the device’s top label).
2. Connect the bench power supply to the power terminals (“+” or “–”).
3. Connect a Field Communicator to the loop across a loop resistor or at the
power/signal terminals on the transmitter.
4. The following message will appear if the communicator has a previous version
of the DDs:
Device Description Not Installed…The Device Description for manufacturer 0x26
model 0x2618 dev rev 8/9 is not installed on the System Card…see Programming
Utility for details on Device Description updates…Do you wish to proceed in forward
compatibility mode?
If this notice does not appear, the latest DD is installed. If the latest version is not
available, the communicator will communicate properly, however, when the
transmitter is configured to utilize the advanced features of the transmitter, the
user will experience trouble communicating and will be prompted to turn the
communicator off. To prevent this from happening, upgrade to the latest DD or
answer NO to the question and default to the generic transmitter functionality.
Note
Emerson recommends installing the latest DD to access the complete functionality. Visit
www.fieldcommunicator.com for information on updating the DD Library.
Field Communicator user interface
Two user interfaces are available to configure this device.
The Device Revision 8 and 9 (HART 5 and 7), DD Revision 1 Fast Key Sequence in
Table 2 may be used for transmitter configuration and startup.

Power the transmitter
An external power supply is required to operate the transmitter.
1. Remove the housing cover (if applicable).
2. Connect the positive power lead to the “+” terminal. Connect the negative
power lead to the “–” terminal.
- If a transient protector is being used, the power leads will now be connected
to the top of the transient protector unit. See the transient label for
indication of “+” and “-“terminal connections.
3. Tighten the terminal screws. When tightening the sensor and power wires, the
max torque is 6 in.-lbs (0.7 N-m).
4. Reattach and tighten the cover (if applicable).
5. Apply power (12 – 42 Vdc).
14
Quick Start Guide
February 2015
Load limitation
The power required across the transmitter power terminals is 12 to 42.4 Vdc (the
power terminals are rated to 42.4 Vdc). To prevent damaging the transmitter, do
not allow terminal voltage to drop below 12.0 Vdc when changing the
configuration parameters.
Ground the transmitter
To ensure proper grounding, it is important that the instrument cable shield be:

trimmed close and insulated from touching the transmitter housing

connected to the next shield if cable is routed through a junction box

connected to a good earth ground at the power supply end
Note
Shielded twisted pair cable should be used for best results. Use 24 AWG or larger wire and do not
exceed 5,000 feet (1500 meters).
Ungrounded thermocouple, mV, and RTD/Ohm inputs
Each process installation has different requirements for grounding. Use the
grounding options recommended by the facility for the specific sensor type, or
begin with grounding Option 1 (the most common).
Option 1
1. Connect sensor wiring shield to the transmitter housing.
2. Ensure the sensor shield is electrically isolated from surrounding fixtures that
may be grounded.
3. Ground signal wiring shield at the power supply end.

Step 5: Perform a loop test
The Loop Test command verifies transmitter output, loop integrity, and
operation of any recorders or similar devices installed in the loop.
Performing a loop test using a Field Communicator
Initiate a loop test
1. Connect an external ampere meter in series with the transmitter loop (so the
power to the transmitter goes through the meter at some point in the loop).
2. From the home screen, enter the Fast Key sequence.
Device dashboard Fast Keys
3, 5, 1
3. In the test loop, check that the transmitter’s actual mA output and the HART
mA reading are the same value. If the readings do not match, either the
transmitter requires an output trim or the meter is malfunctioning. After
completing the test, the display returns to the loop test screen and allows the
user to choose another output value.
4. To end the Loop Test, select End and Enter.
Performing a loop test using AMS Device Manager
1. Right click on the device and select Service Tools.
2. In the left navigation pane select Simulate.
3. On the Simulate Tab in the Analog Output Verification group box, select the
Perform Loop Test button.
4. Follow the guided instructions and select Apply when complete.
