IMPORTANT NOTICE
This installation guide provides basic guidelines for the Rosemount
644. It does not provide instructions for detailed configuration,
diagnostics, maintenance, service, troubleshooting, or installation.
Refer to the 644 Reference Manual (document number
00809-0100-4728) for more instruction. The manual and this QIG
are also available electronically on www.rosemount.com.
WARNING
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 Product
Certifications for any restrictions associated with a safe installation.
In an Explosion-Proof/Flame-Proof installation, do not remove the
transmitter covers when power is applied to the unit.
Process leaks may cause harm or result in death
• Install and tighten thermowells or sensors before applying
pressure.
• Do not remove the thermowell while in operation.
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.

Rosemount 644
STEP 1: CONFIGURE (BENCH CALIBRATION)
The 644 communicates using the HART Communicator
(communication requires a loop resistance between 250 and 1100
ohms. Do not operate when power is below 12 Vdc at the transmitter
terminal). Refer to the 644 Reference Manual (document number
00809-0100-4728) and the HART Communicator Reference Manual
(document number 00809-0100-4275) for more information.
Update the HART Communicator Software
The HART Communicator Field Device Revision Dev v6, DD v1 or
higher is required for complete functionality. The device will
communicate with all previous 644 DD revisions.
Perform the following steps to determine if an upgrade is required.
1. Connect the sensor (see the wiring diagram located on the inside
of the housing cover).
2. Connect the bench power supply to the power terminals (“+” or “–”).
3. Connect a HART 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 device descriptors (DDs).
NOTICE: Upgrade the communicator software to access new
XMTR functions. Continue with old description?
NOTE:
If this notice does not appear, the latest DD is installed. If the latest
version is not available, the communicator will communicate
properly. But, when the transmitter is configured to utilize the
advanced features of the transmitter (such as one of the added
sensor input types), 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

STEP 4: CONNECT THE WIRING
• Wiring diagrams are located inside the terminal block cover.
• An external power supply is required to operate the transmitter.
• 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.
Power the Transmitter
1. Remove the terminal block cover (if applicable).
2. Connect the positive power lead to the “+” terminal. Connect
the negative power lead to the “–” terminal.
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).

Ground the Transmitter
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.
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 select:
644H and 644R:
1 Device Setup, 2 Diag/Serv, 1 Test Device, 1 Loop Test.
3. Select a discreet milliampere level for the transmitter to output. At
Choose Analog Output select 1 4mA, 2 20mA or select 3 Other to
manually input a value between 4 and 20 milliamperes. Select
Enter to show the fixed output. Select OK.
4. In the test loop, check 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 current
meter is malfunctioning.
5. After completing the test, the display returns to the loop test screen
and allows the user to choose another output value. To end the
Loop Test, Select 5 End and Enter.
