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 QSG are 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 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.

Quick Start Guide

Step 1: Configure (bench calibration)

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). Refer to the 644 Reference Manual (document number 00809-0100-4728) and the Field Communicator Reference Manual (document number 00809-0100-4275) for more information.

Update the field communicator software

The field 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 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 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.

Quick Start Guide

Step 4: Mount the transmitter

Mount the transmitter at a high point in the conduit run to prevent moisture from draining into the transmitter housing.

Typical connection head installation

Head mount transmitter with DIN plate style sensor

1. Attach the thermowell to the pipe or process container wall. Install and tighten the thermowell before applying process pressure.

2. Verify the transmitter failure mode switch.

3. Assemble the transmitter to the sensor. Push the transmitter mounting screws through the sensor mounting plate and insert the snap rings (optional) into the transmitter mounting screw groove.

4. Wire the sensor to the transmitter (see “Wire and apply power” on page 12 for more information).
