Manual Revision

CONSIDERATIONS General Electrical temperature sensors such as RTDs and thermocouples produce

low-level signals proportional to their sensed temperature. The 644 converts the low-level sensor signal to digital Profibus PA signal that is relatively insensitive to lead length and electrical noise. This signal is then transmitted to the control room via two wires.

Commissioning The transmitter can be commissioned before or after installation. It may be

useful to commission it on the bench, before installation, to ensure proper operation and to become familiar with its functionality. Make sure the instruments in the loop are installed in accordance with intrinsically safe, FISCO, or non-incendive field wiring practices.

Mechanical Location

When choosing an installation location and position, take into account the need for access to the transmitter.

Special Mounting

Special mounting hardware is available for mounting a 644 head mount transmitter to a DIN rail, or assembling a new 644 head mount to an existing threaded sensor connection head (former option code L1).

Electrical Proper electrical installation is necessary to prevent errors due to sensor lead

resistance and electrical noise. For best results, shielded cable should be used in electrically noisy environments.

Make wiring connections through the cable entry in the side of the connection head. Be sure to provide adequate clearance for cover removal.

Environmental The transmitter electronics module is permanently sealed within the housing,

resisting moisture and corrosive damage. Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications.

Temperature Effects

The transmitter will operate within specifications for ambient temperatures between –40 and 185 °F (–40 and 85 °C). Heat from the process is transferred from the thermowell to the transmitter housing. If the expected process temperature is near or beyond specification limits, consider the use of additional thermowell lagging, and extension nipple, or a remote mounting configuration to isolate the transmitter from the process.

Reference Manual

00809-0300-4728, Rev AA

January 2011

Figure 1-1 provides an example of the relationship between transmitter housing temperature rise and extension length.

Example

The transmitter specification limit is 85 °C. If the ambient temperature is 55 °C and the process temperature to be measured is 800 °C, the maximum permissible connection head temperature rise is the transmitter specification limit minus the ambient temperature (moves 85 to 55 °C), or 30 °C.

In this case, an extension of 100 mm meets this requirement, but 125 mm provides a margin of 8 °C, thereby reducing any temperature effects in the transmitter.

CONFIGURATION GUIDELINES

Profile 3.02 Identification Number Adaptation Mode

To configure on the bench, required equipment includes a power supply, a class 2 master with DP/PA coupler, proper cable, and terminators. Verify that the Security hardware jumper is set to the OFF position in order to proceed with configuration. See Figure 4-2 for jumper location.

Setup for the Rosemount 644 can be done via Siemens SIMATIC software or any other DD or DTM based Class 2 master.

Rosemount 644 Profibus Profile 3.02 devices are set to Identification Number Adaptation Mode when shipped from the factory. This mode allows the transmitter to communicate with any Profibus class 1 master with either the generic Profile GSD (9700) or Rosemount 644 specific GSD (1039).

PDM

Block Modes When configuring a device with a class 2 master, it is best practice to set

blocks to OOS when downloading parameters that affect the transmitter output. However, the 644 will allow configuration changes made in AUTO to be downloaded to the device. This prevents the class one master from seeing a jump in output without a status change. Setting the blocks OOS and back into Auto is done automatically when using the class two master configuration wizards within the Rosemount 644 DD or DTM. This is done so no additional action is required when configuring the device.

Configuration Tools The Rosemount 644 can be configured through the factory at order entry or

using a class 2 master. The C1 option code must be ordered to obtain addressing and configuration of the device at the factory.

Class 2 masters require either DD or DTM files for configuration. These files can be found at www.rosemount.com or by contacting your local Emerson Process representative.

The remainder of this section will cover the configuration tasks using the Class 2 master configuration tool.

NOTE

Instructions in this section use the terminology found in the class 2 master. See Appendix C: Profibus Block Information to cross reference parameters between the class2 master, and the Profibus specification.

BASIC SETUP TASKS Device Description Before configuring the device, ensure the host has the appropriate Device

Description file revision for this device. The device descriptor can be found on www.rosemount.com. The initial release of the Rosemount 644 with Profibus PA protocol is device revision 1.

Assign Address The Rosemount 644 is shipped with a temporary address of 126. This must

be changed to a unique value between 1 and 125 in order to establish communication with the class 1 master. Usually, addresses 1-2 are reserved for masters, therefore transmitter addresses between 3 and 125 are recommended for the device.

Address can be set using either:

• Factory Configuration (C1 option code)

• Class 2 master – see respective class 2 master manual for setting instrument addresses

Process Alarm parameters are defined as follows

• HI-HI Alarm: Changes Output Status to Good – Critical Alarm – Hi Limit

• HI Warning: Changes Output Status to Good – Advisory Alarm – Hi Limit

• LO Warning: Changes Output Status to Good – Advisory Alarm – Lo Limit

• LO-LO Alarm: Changes Output Status to Good – Critical Alarm – Lo Limit

• Alarm Hysteresis: Amount the output value must pass back into range before alarm is cleared.

Example: Upper Alarm = 100 °C. Alarm Hysteresis = 0.5 °C. After activation at 100 °C, the alarm will clear once the output goes below

99.5 °C = 100 - 0.5 °C.

Process Alerts can be set using,

Simulation Simulation is in the AI block and used to verify the output from the transducer

block. The Rosemount 644 has a simulation jumper located on the transmitter puck top cover that must be set to the ON position in order to simulate.

NOTE

This jumper position is ignored when the transmitter is initially powered. The jumper position must be changed while the transmitter is powered to activate simulation. If power is removed and restored, the simulation mode will be OFF regardless of jumper position.

With simulation enabled, the actual measurement value has no impact on the OUT value or the status. The OUT value will equal the simulated value from the transducer block plus any scaling or linearization effects performed in the AI block.

To change the AI OUT units the PV Scale and OUT Scale need to be updated

Example: (All values are arbitrary)

The default configuration of the device is:

4-wire PT100_A_385 AI.OUT = 23 °C PRIMARY_VALUE_UNIT = °C PV_SCALE = 100, 0 PV.VALUE = 23 °C OUT_SCALE = 100,0, °C SV.VALUE = 23 °C USL = 850 °C LSL = -200 °C

If the user desires to change the units to °F, only the parameters in Bold will change with the PRIMARY_VALUE_UNIT. The AI.OUT will stay in °C until the

PV_SCALE and OUT_SCALE are configured to match each other. (This can

be with the measurement range or the sensor limits.

4-wire PT100_A_385 AI.OUT = 23 °C

PRIMARY_VALUE_UNIT = °C PV_SCALE = 212, 32 PV.VALUE = 73 °C OUT_SCALE = 100,0, °C SV.VALUE = 73 ° C USL = 1562 °C LSL = -328 °C

So the following change is needed:

PV_SCALE = 1562,-328 (make the same as USL and LSL) OUT_SCALE = 1562,-328, °F (make the same as PV_SCALE)

WIRING All power to the transmitter is supplied over the signal wiring. Use ordinary

copper wire of sufficient size to ensure that the voltage across the transmitter power terminals does not drop below 9 Vdc for Profibus PA. If the sensor is installed in a high-voltage environment and a fault condition or installation error occurs, the sensor leads and transmitter terminals could carry lethal voltages. Use extreme caution when making contact with the leads and terminals.

NOTE

Do not apply high voltage (e.g., ac line voltage) to the transmitter terminals. Abnormally high voltage can damage the unit. (Sensor and transmitter power terminals are rated to 42.4 Vdc. A constant 42.4 volts across the sensor terminals may damage the unit.)

The transmitters will accept inputs from a variety of RTD and thermocouple types. Refer to Figure 4-1 when making sensor connections. Refer to Figure 4-2 for Profibus installations.

Use the following steps to wire the power and sensor to the transmitter:

1. Connect the positive power lead to the .+. terminal. Connect the negative power lead to the .-. terminal.

2. Tighten the terminal screws. When tightening the sensor and power wires, the max torque is 6-in.-lbs (0.7 N-m).

3. Apply power.

RTD or Ohm Inputs

The transmitters will accept a variety of RTD configurations, including 2-wire, 3-wire, and 4-wire. If the transmitter is mounted remotely from a 3-wire or 4-wire RTD, it will operate within specifications, without recalibration, for lead wire resistances of up to 60 ohms per lead (equivalent to 6,000 feet of 20 AWG wire). In this case, the leads between the RTD and transmitter should be shielded. If using only two leads, both RTD leads are in series with the sensor element, so significant errors can occur if the lead lengths exceed three feet of 20 AWG wire (approximately 0.05 °C/ft). For longer runs, attach a third or fourth lead as described above.

Sensor Lead Wire Resistance Effect– RTD Input

When using a 4-wire RTD, the effect of lead resistance is eliminated and has no impact on accuracy. However, a 3-wire sensor will not fully cancel lead resistance error because it cannot compensate for imbalances in resistance between the lead wires. Using the same type of wire on all three lead wires will make a 3-wire RTD installation as accurate as possible. A 2-wire sensor will produce the largest error because it directly adds the lead wire resistance to the sensor resistance. For 2- and 3-wire RTDs, an additional lead wire resistance error is induced with ambient temperature variations. The table and the examples shown below help quantify these errors.

Profibus PA Installation

Powered over Profibus PA with standard Profibus power supplies; the transmitter operates between 9.0 and 32.0 Vdc, 11 mA maximum. Transmitter power terminals are rated to 42.4 Vdc. The power terminals on the 644 with Profibus are polarity insensitive.

Ground the Transmitter The transmitter will operate with the current signal loop either floating or

grounded. However, the extra noise in floating systems affects many types of readout devices. If the signal appears noisy or erratic, grounding the current signal loop at a single point may solve the problem. The best place to ground the loop is at the negative terminal of the power supply. Do not ground the current signal loop at more than one point.

The transmitter is electrically isolated to 500 Vdc/ac rms (707 Vdc), so the input circuit may also be grounded at any single point. When using a grounded thermocouple, the grounded junction serves as this point.

Neither side of the loop should be grounded on Profibus PA devices. Only the shield wire should be grounded.

NOTE

Do not ground the signal wire at both ends.

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).

If trim fails the transmitter will automatically revert to factory trim. Excessive correction or sensor failure could cause device status to read “calibration error”. To clear this, trim the transmitter.

Recall Factory Trim

To recall a factory trim on the transmitter, run the Recall Factory Trim. If your system does not support methods, manually configure the Transducer Block parameters listed below.

1. Set TARGET_MODE to OOS

2. Set SENSOR_CAL_METHOD to Factory Trim.

3. Set SENSOR_CAL_DATE to the current date.

4. Set SENSOR_CAL_WHO to the person responsible for the calibration.

5. Set SENSOR _CAL_LOC to the calibration location.

6. Set TARGET_MODE to AUTO.

Tagging

Hardware

• 13 characters total

• Tags are adhesive labels

• Permanently attached to transmitter

• Character height is

/16-in (1.6 mm)

Software

• Order with C1 option

• The transmitter can store up to 13 characters for Profibus PA. If no characters are specified, the first 8 characters of the hardware tag are the default.

Considerations

Special Mounting Considerations

See “Mounting Kits for 644H” on page A-8 for the special hardware that is available to:

• Mount a 644H to a DIN rail. (see Table A-3 on page A-12)

• Retrofit a new 644H to replace an existing 644H transmitter in an existing threaded sensor connection head.(see Table A-3 on page A-12)

External Ground Screw Assembly

The external ground screw assembly can be ordered by specifying code G1 when an enclosure is specified. However, some approvals include the ground screw assembly in the transmitter

shipment, hence it is not necessary to order code G1. The table below identifies which approval options include the external ground screw assembly and which do not.
