Electrical shock can result in death or serious injury.

• Avoid contact with the leads and terminals.

Process leaks could result in death or serious injury.

• Install and tighten all four flange bolts before applying pressure.

• Do not attempt to loosen or remove flange bolts while the transmitter is in service.

Replacement equipment or spare parts not approved by Emerson Process Management for use as spare parts could reduce the pressure retaining capabilities of the transmitter and may render the instrument dangerous.

• Use only bolts supplied or sold by Emerson Process Management as spare parts.

• Refer to page A-25 for a complete list of spare parts.

Improper assembly of manifolds to traditional flange can damage sensor module.

• For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (i.e., bolt hole) but must not contact sensor module housing.

GENERAL CONSIDERATIONS

MECHANICAL CONSIDERATIONS

Measurement accuracy depends upon proper installation of the transmitter and impulse piping. Mount the transmitter close to the process and use a minimum of piping to achieve best accuracy. Also, consider the need for easy access, personnel safety, practical field calibration, and a suitable transmitter environment. Install the transmitter to minimize vibration, shock, and temperature fluctuation.

IMPORTANT

Install the enclosed pipe plug (found in the box) in unused conduit opening with a minimum of five threads engaged to comply with explosion-proof requirements.

For material compatibility considerations, see document number 00816-0100-3045 on www.emersonprocess.com/rosemount.

NOTE

For steam service or for applications with process temperatures greater than the limits of the transmitter, do not blow down impulse piping through the transmitter. Flush lines with the blocking valves closed and refill lines with water before resuming measurement.

NOTE

When the transmitter is mounted on its side, position the Coplanar flange to ensure proper venting or draining. Mount the flange as shown in Figure 2-8 on page 2-16, keeping drain/vent connections on the bottom for gas service and on the top for liquid service.

ENVIRONMENTAL CONSIDERATIONS

2-2

Best practice is to mount the transmitter in an environment that has minimal ambient temperature change. The transmitter electronics temperature operating limits are –40 to 185 °F (–40 to 85 °C). Refer to Appendix A: Reference Data that lists the sensing element operating limits. Mount the transmitter so that it is not susceptible to vibration and mechanical shock and does not have external contact with corrosive materials.

Impulse Piping The piping between the process and the transmitter must accurately transfer

the pressure to obtain accurate measurements. There are six possible sources of impulse piping error: pressure transfer, leaks, friction loss (particularly if purging is used), trapped gas in a liquid line, liquid in a gas line, and density variations between the legs.

The best location for the transmitter in relation to the process pipe is dependent on the process. Use the following guidelines to determine transmitter location and placement of impulse piping:

• Keep impulse piping as short as possible.

• For liquid service, slope the impulse piping at least 1 in./foot (8 cm/m) upward from the transmitter toward the process connection.

• For gas service, slope the impulse piping at least 1 in./foot (8 cm/m) downward from the transmitter toward the process connection.

• Avoid high points in liquid lines and low points in gas lines.

• Make sure both impulse legs are the same temperature.

• Use impulse piping large enough to avoid friction effects and blockage.

• Vent all gas from liquid piping legs.

• When using a sealing fluid, fill both piping legs to the same level.

• When purging, make the purge connection close to the process taps and purge through equal lengths of the same size pipe. Avoid purging through the transmitter.

• Keep corrosive or hot (above 250 °F [121 °C]) process material out of direct contact with the sensor module and flanges.

• Prevent sediment deposits in the impulse piping.

• Maintain equal leg of head pressure on both legs of the impulse piping.

• Avoid conditions that might allow process fluid to freeze within the process flange.

LIQUID SERVICE GAS SERVICE STEAM SERVICE

Reference Manual

00809-0200-4101, Rev AA

Mounting Requirements

Impulse piping configurations depend on specific measurement conditions. Refer to Figure 2-8 for examples of the following mounting configurations:

Liquid Flow Measurement

• Place taps to the side of the line to prevent sediment deposits on the process isolators.

• Mount the transmitter beside or below the taps so gases vent into the process line.

• Mount drain/vent valve upward to allow gases to vent.

Gas Flow Measurement

• Place taps in the top or side of the line.

• Mount the transmitter beside or above the taps so to drain liquid into the process line.

Steam Flow Measurement

• Place taps to the side of the line.

• Mount the transmitter below the taps to ensure that impulse piping will remain filled with condensate.

• In steam service above 250 °F (121 °C), fill impulse lines with water to prevent steam from contacting the transmitter directly and to ensure accurate measurement start-up.

NOTE

For steam or other elevated temperature services, it is important that temperatures at the process connection do not exceed the transmitter’s process temperature limits. See “Process Temperature Limits” on page A-7 for details.

Process Connections Coplanar or Traditional Process Connection

Install and tighten all four flange bolts before applying pressure, or process leakage will result. When properly installed, the flange bolts will protrude through the top of the sensor module housing. Do not attempt to loosen or remove the flange bolts while the transmitter is in service.

Flange Adaptors:

Rosemount 2051DP and GP process connections on the transmitter flanges

are

/4–18 NPT. Flange adapters are available with standard 1/2–14 NPT Class 2 connections. The flange adapters allow users to disconnect from the process by removing the flange adapter bolts. Use plant-approved lubricant or sealant when making the process connections. Refer to Dimensional Drawings on page 2-3 for the distance between pressure connections. This distance may be varied ± adapters.

To install adapters to a Coplanar flange, perform the following procedure:

1. Remove the flange bolts.

2. Leaving the flange in place, move the adapters into position with the o-ring installed.

3. Clamp the adapters and the Coplanar flange to the transmitter sensor module using the larger of the bolts supplied.

4. Tighten the bolts. Refer to “Flange Bolts” on page 2-13 for torque specifications.

Rosemount 2051

Whenever you remove flanges or adapters, visually inspect the PTFE o-rings. Replace with o-ring designed for Rosemount transmitter if there are any signs of damage, such as nicks or cuts. Undamaged o-rings may be reused. If you replace the o-rings, retorque the flange bolts after installation to compensate for cold flow. Refer to the process sensor body reassembly procedure in Section 5: Troubleshooting.

Failure to install proper flange adapter O-rings may cause process leaks, which can result in

death or serious injury. The two flange adapters are distinguished by unique O-ring grooves.

Only use the O-ring that is designed for its specific flange adapter, as shown below.

Tagging Commissioning (Paper) Tag

When commissioning more than one device on a fieldbus segment, it can be difficult to identify which device is at a particular location. A removable tag provided with the transmitter can aid in this process by linking the Device ID and a physical location. TheDevice ID is a unique code that identifies a particular device in the absence of a device tag. The device tag is used by the customer as an operational identification for the device and is usually defined by the Piping and Instrumentation Diagram (P & ID).

2-20

The installer should note the physical location in both places on the removable commissioning tag and tear off the bottom portion. This should be done for each device on the segment. The bottom portion of the tags can be used for commissioning the segment in the control system, providing a direct link between the Device ID and the tag location.

Perform the following procedure to make wiring connections:

1. Remove the housing cover on terminal compartment side. Do not remove the cover in explosive atmospheres when the circuit is live. Signal wiring supplies all power to the transmitter.

2. Connect the leads to the two F to Figure 2-14.

3. Plug and seal unused conduit connection on the transmitter housing to avoid moisture accumulation in the terminal side. Install wiring with a drip loop. Arrange the drip loop so the bottom is lower than the conduit connections and the transmitter housing.

Power Supply

External power supply required; transmitters operate on 9.0 to 32.0 V dc transmitter terminal voltage.

Transient Protection Terminal Block

The transmitter will withstand electrical transients of the energy level usually encountered in static discharges or induced switching transients. However, high-energy transients, such as those induced in wiring from nearby lightning strikes, can damage the transmitter.

The transient protection terminal block can be ordered as an installed option (Option Code T1 in the transmitter model number) or as a spare part to retrofit existing 2051 transmitters in the field. See “Spare Parts” on page A-38 for spare part numbers. The lightning bolt symbol shown in Figure 2-14 and Figure identifies the transient protection terminal block.

2-23

Rosemount 2051

NOTE

The transient protection terminal block does not provide transient protection unless the transmitter case is properly grounded. Use the guidelines to ground the transmitter case. Refer to page 2-25.

Do not run the transient protection ground wire with signal wiring as the ground wire may carry excessive current if a lightning strike occurs.

Jumpers Security

After you configure the transmitter, you may want to protect the configuration data from unwarranted changes. Each transmitter is equipped with a security jumper that can be positioned “ON” to prevent the accidental or deliberate change of configuration data. The jumper is located on the front side of the electronics module and is labeled SECURITY (see Figure 2-15).

If the transmitter write protection jumper is in the “ON” position, the transmitter will not accept any “writes” to its memory. Configuration changes, such as digital trim and reranging, cannot take place when the transmitter security is on.

Reference Manual

00809-0200-4101, Rev AA

July 2008

NOTE

If the security jumper is not installed, the transmitter will continue to operate in the security OFF configuration.

Configuring Transmitter Security Jumper Procedure

To reposition the jumper, follow the procedure described below.

1. Do not remove the transmitter covers in explosive atmospheres when the circuit is live. If the transmitter is live, set the loop to manual and remove power.

2. Remove the housing cover opposite the field terminal side. Do not remove the transmitter covers in explosive atmospheres when the circuit is live.

3. Reposition the jumpers as desired. Refer to Figure 2-15.

4. Reattach the transmitter cover. Always ensure a proper seal by installing the electronics housing covers so that metal contacts metal to meet explosion-proof requirements.

Simulate

The simulate jumper is used in conjunction with the Analog Input (AI) function block. This switch is used to simulate the measurement. To enable the simulate feature, insert the jumper across “ENABLE” (see Figure 2-15) while the transmitter is powered.

2-24

NOTE

When power is cycled to the transmitter, simulate is automatically disabled regardless of the position of the jumper. This prevents the transmitter from being accidentally left in simulate mode. Therefore, to enable the simulate feature, the jumper must be inserted after power is applied to the transmitter.

Grounding Use the following techniques to properly ground the transmitter case:

Transmitter Case

Always ground the transmitter case in accordance with national and local electrical codes. The most effective transmitter case grounding method is a direct connection to earth ground with minimal impedance. Methods for grounding the transmitter case include:

• Internal Ground Connection: The Internal Ground Connection screw

is inside the FIELD TERMINALS side of the electronics housing. This screw is identified by a ground symbol ( ). The ground connection screw is standard on all Rosemount 2051 transmitters. Refer to Figure 2-16.

• External Ground Assembly: This assembly is included with the

optional transient protection terminal block (Option Code T1), and it is included with various hazardous location certifications. The External Ground Assembly can also be ordered with the transmitter (Option Code V5), or as a spare part. See “Spare Parts” on page A-25. Refer to Figure 2-17 for location of the External Ground Screw.

Rosemount 305 Integral Manifold Installation Procedure

To install a 305 Integral Manifold to a 2051 transmitter:

1. Inspect the PTFE sensor module o-rings. Undamaged o-rings may be reused. If the o-rings are damaged (if they have nicks or cuts, for example), replace with o-rings designed for Rosemount transmitter.

IMPORTANT

If replacing the o-rings, take care not to scratch or deface the o-ring grooves or the surface of the isolating diaphragm while you remove the damaged o-rings.

2. Install the Integral Manifold on the sensor module. Use the four 2.25-in. manifold bolts for alignment. Finger tighten the bolts, then tighten the bolts incrementally in a cross pattern to final torque value. See “Flange Bolts” on page 2-13 for complete bolt installation information and torque values. When fully tightened, the bolts should extend through the top of the sensor module housing.

3. If the PTFE sensor module o-rings have been replaced, the flange bolts should be re-tightened after installation to compensate for cold flow of the o-rings.

NOTE

Always perform a zero trim on the transmitter/manifold assembly after installation to eliminate mounting effects.

Rosemount 306 Integral Manifold Installation Procedure

Rosemount 304 Conventional Manifold Installation Procedure

The 306 Manifold is for use only with a 2051T In-line transmitter.

Assemble the 306 Manifold to the 2051T In-line transmitter with a thread sealant.

To install a 304 Conventional Manifold to a 2051 transmitter:

1. Align the Conventional Manifold with the transmitter flange. Use the four manifold bolts for alignment.

2. Finger tighten the bolts, then tighten the bolts incrementally in a cross pattern to final torque value. See “Flange Bolts” on page 2-6 for complete bolt installation information and torque values. When fully tightened, the bolts should extend through the top of the sensor module housing.

3. Leak-check assembly to maximum pressure range of transmitter.

LIQUID LEVEL MEASUREMENT

Differential pressure transmitters used for liquid level applications measure hydrostatic pressure head. Liquid level and specific gravity of a liquid are factors in determining pressure head. This pressure is equal to the liquid height above the tap multiplied by the specific gravity of the liquid. Pressure head is independent of volume or vessel shape.

Open Vessels A pressure transmitter mounted near a tank bottom measures the pressure of

the liquid above.

Make a connection to the high pressure side of the transmitter, and vent the low pressure side to the atmosphere. Pressure head equals the liquid’s specific gravity multiplied by the liquid height above the tap.

Zero range suppression is required if the transmitter lies below the zero point of the desired level range. Figure 2-19 shows a liquid level measurement example.

Closed Vessels Pressure above a liquid affects the pressure measured at the bottom of a

closed vessel. The liquid specific gravity multiplied by the liquid height plus the vessel pressure equals the pressure at the bottom of the vessel.

To measure true level, the vessel pressure must be subtracted from the vessel bottom pressure. To do this, make a pressure tap at the top of the vessel and connect this to the low side of the transmitter. Vessel pressure is then equally applied to both the high and low sides of the transmitter. The resulting differential pressure is proportional to liquid height multiplied by the liquid specific gravity.

Dry Leg Condition

Low-side transmitter piping will remain empty if gas above the liquid does not condense. This is a dry leg condition. Range determination calculations are the same as those described for bottom-mounted transmitters in open vessels, as shown in Figure 2-19.

Wet Leg Condition

Condensation of the gas above the liquid slowly causes the low side of the transmitter piping to fill with liquid. The pipe is purposely filled with a convenient reference fluid to eliminate this potential error. This is a wet leg condition.

The reference fluid will exert a head pressure on the low side of the transmitter. Zero elevation of the range must then be made. See Figure 2-20

ensure the safety of the personnel performing the operations. Information that raises potential safety issues is indicated by a warning symbol ( ). Refer to the following safety messages before performing an operation preceded by this symbol.

Warnings

Explosions can result in death or serious injury.

• Do not remove the transmitter covers in explosive environments when the circuit is live.

• Transmitter covers must be fully engaged to meet explosion proof requirements.

• Before connecting a configuration tool in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or nonincendive field wiring practices.

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.

DEVICE CAPABILITIES

Link Active Scheduler The Rosemount 2051 can be designated to act as the backup Link Active

Scheduler (LAS) in the event that the LAS is disconnected from the segment. As the backup LAS, the 2051 will take over the management of communications until the host is restored.

The host system may provide a configuration tool specifically designed to designate a particular device as a backup LAS.

Capabilities Block Execution times

Analog Input = 30 ms PID = 45 ms

GENERAL BLOCK INFORMATION

Modes

The Resource, Transducer, and all function blocks in the device have modes of operation. These modes govern the operation of the block. Every block supports both automatic (AUTO) and out of service (OOS) modes. Other modes may also be supported.

Changing Modes

To change the operating mode, set the MODE_BLK.TARGET to the desired mode. After a short delay, the parameter MODE_BLOCK.ACTUAL should reflect the mode change if the block is operating properly.

Permitted Modes

It is possible to prevent unauthorized changes to the operating mode of a block. To do this, configure MODE_BLOCK.PERMITTED to allow only the desired operating modes. It is recommended to always select OOS as one of the permitted modes.

Types of Modes

For the procedures described in this manual, it will be helpful to understand the following modes:

AUTO

The functions performed by the block will execute. If the block has any outputs, these will continue to update. This is typically the normal operating mode.

3-2

Out of Service (OOS)

The functions performed by the block will not execute. If the block has any outputs, these will typically not update and the status of any values passed to downstream blocks will be “BAD”. To make some changes to the configuration of the block, change the mode of the block to OOS. When the changes are complete, change the mode back to AUTO.

MAN

In this mode, variables that are passed out of the block can be manually set for testing or override purposes.

Other Types of Modes

Other types of modes are Cas, RCas, ROut, IMan and LO. Some of these may be supported by different function blocks in the Rosemount 2051. For more information, see the Function Block manual, document 00809-0100-4783.

NOTE

When an upstream block is set to OOS, this will impact the output status of all downstream blocks. The figure below depicts the hierarchy of blocks:

Simulation Simulation is the functionality of the AI block. To support testing, either

change the mode of the block to manual and adjust the output value or enable simulation through the configuration tool and manually enter a value for the measurement value and its status (this single value will apply to all outputs). In both cases, first set the ENABLE jumper on the field device.

RESOURCE BLOCK

FEATURES and FEATURES_SEL

NOTE

All fieldbus instruments have a simulation jumper. As a safety measure, the jumper has to be reset every time there is a power interruption. This measure is to prevent devices that went through simulation in the staging process from being installed with simulation enabled.

With simulation enabled, the actual measurement value has no impact on the

OUT value or the status. The OUT values will all have the same value as

determined by the simulate value.

The FEATURES parameter is read only and defines which features are supported by the 2051. Below is a list of the FEATURES the 2051 supports.

FEATURES_SEL is used to turn on any of the supported features that are found in the FEATURES parameter. The default setting of the Rosemount 2051 does not select any of these features. Choose one or more of the supported features if any.

UNICODE

All configurable string variables in the 2051, except tag names, are octet strings. Either ASCII or Unicode may be used. If the configuration device is generating Unicode octet strings, you must set the Unicode option bit.

REPORTS

The 2051 supports alert reports. The Reports option bit must be set in the features bit string to use this feature. If it is not set, the host must poll for alerts. If this bit is set, the transmitter will actively report alerts.

SOFT W LOCK and HARD W LOCK

Inputs to the security and write lock functions include the hardware security switch, the hardware and software write lock bits of the FEATURE_SEL parameter, the WRITE_LOCK parameter, and the DEFINE_WRITE_LOCK parameter.

The WRITE_LOCK parameter prevents modification of parameters within the device except to clear the WRITE_LOCK parameter. During this time, the block will function normally updating inputs and outputs and executing algorithms. When the WRITE_LOCK condition is cleared, a WRITE_ALM alert is generated with a priority that corresponds to the WRITE_PRI parameter.

The FEATURE_SEL parameter enables the user to select a hardware or software write lock or no write lock capability. To enable the hardware security function, enable the HW_SEL bit in the FEATURE_SEL parameter. When this bit has been enabled the WRITE_LOCK parameter becomes read only and will reflect the state of the hardware switch. In order to enable the software write lock, the SW_SEL bit must be set in the FEATURE_SEL parameter. Once this bit is set, the WRITE_LOCK parameter may be set to “Locked” or “Not Locked.” Once the WRITE_LOCK parameter is set to “Locked” by either the software or the hardware lock, all user requested writes as determined by the DEFINE_WRITE_LOCK parameter shall be rejected.

The DEFINE_WRITE_LOCK parameter allows the user to configure whether the write lock functions (both software and hardware) will control writing to all blocks, or only to the resource and transducer blocks. Internally updated data such as process variables and diagnostics will not be restricted by the security switch.

The following table displays all possible configurations of the WRITE_LOCK parameter.

Configure the AI block

A minimum of four parameters are required to configure the AI Block. The parameters are described below with example configurations shown at the end of this section.

CHANNEL

Select the channel that corresponds to the desired sensor measurement. The 2051 measures both pressure (channel 1) and sensor temperature (channel

2).

Table 3-1. I/O Channel Definitions

Channel Number Channel Description

1 differential pressure in AI.XD_SCALE units 2 sensor temperature in AI.XD_SCALE units

L_TYPE

The L_TYPE parameter defines the relationship of the sensor measurement (pressure or sensor temperature) to the desired output of the AI Block (e.g. pressure, level, flow, etc.). The relationship can be direct, indirect, or indirect square root.

Direct

Select direct when the desired output will be the same as the sensor measurement (pressure or sensor temperature).

Indirect

Select indirect when the desired output is a calculated measurement based on the sensor measurement (e.g. a pressure measurement is made to determine level in a tank). The relationship between the sensor measurement and the calculated measurement will be linear.

Indirect Square Root

Select indirect square root when the desired output is an inferred measurement based on the sensor measurement and the relationship between the sensor measurement and the inferred measurement is square root (e.g. flow).

XD_SCALE and OUT_SCALE

The XD_SCALE and OUT_SCALE each include three parameters: 0%, 100%, and, engineering units. Set these based on the L_TYPE:

L_TYPE is Direct

When the desired output is the measured variable, set the XD_SCALE to the “Primary_Value_Range”. This is found in the Sensor Transducer Block. Set OUT_SCALE to match XD_SCALE.

L_TYPE is Indirect

When an inferred measurement is made based on the sensor measurement, set the XD_SCALE to represent the operating range that the sensor will see in the process. Determine the inferred measurement values that correspond to the XD_SCALE 0 and 100% points and set these for the OUT_SCALE.

Filtering The filtering feature changes the response time of the device to smooth

variations in output readings caused by rapid changes in input. Adjust the filter time constant (in seconds) using the PV_FTIME parameter. Set the filter time constant to zero to disable the filter feature.

Figure 3-3. Analog Input PV_FTIME filtering Diagram.

Low Cutoff When the converted input value is below the limit specified by the LOW_CUT

parameter, and the Low Cutoff I/O option (IO_OPTS) is enabled (True), a value of zero is used for the converted value (PV). This option is useful to eliminate false readings when the differential pressure measurement is close to zero, and it may also be useful with zero-based measurement devices such as flowmeters.

NOTE Low Cutoff is the only I/O option supported by the AI block. Set the I/O option in Manual or Out of Service mode only.

Process Alarms Process Alarm detection is based on the OUT value. Configure the alarm

limits of the following standard alarms:

• High (HI_LIM)

• High high (HI_HI_LIM)

• Low (LO_LIM)

• Low low (LO_LO_LIM)

In order to avoid alarm chattering when the variable is oscillating around the alarm limit, an alarm hysteresis in percent of the PV span can be set using the ALARM_HYS parameter. The priority of each alarm is set in the following parameters:

•HI_PRI

• HI_HI_PRI

•LO_PRI

• LO_LO_PRI

Alarm Priority Alarms are grouped into five levels of priority:

Priority

Number

0 The alarm condition is not used. 1 An alarm condition with a priority of 1 is recognized by the system, but is not

2 An alarm condition with a priority of 2 is reported to the operator.

3-7 Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority.

8-15 Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.

Priority Description

reported to the operator.

Status Options Status Options (STATUS_OPTS) supported by the AI block are shown below:

Propagate Fault Forward

If the status from the sensor is Bad, Device failure or Bad, Sensor failure, propagate it to OUT without generating an alarm. The use of these sub-status in OUT is determined by this option. Through this option, the user may determine whether alarming (sending of an alert) will be done by the block or propagated downstream for alarming.

Uncertain if Limited

Set the output status of the Analog Input block to uncertain if the measured or calculated value is limited.

BAD if Limited

Set the output status to Bad if the sensor is violating a high or low limit.

Uncertain if Man Mode

Set the output status of the Analog Input block to uncertain if the actual mode of the block is Man.

NOTES The instrument must be in Out of Service mode to set the status option.

Advanced Features The AI Function Block provides added capability through the addition of the

following parameters:

ALARM_SEL

ALARM_SEL allows one or more of the process alarm conditions detected by the AI function block to be used in setting its OUT_D parameter.

OUT_D

OUT_D is the discrete output of the AI function block based on the detection of process alarm condition(s). This parameter may be linked to other function blocks that require a discrete input based on the detected alarm condition.

LCD BLOCK The LCD can display up to four different parameters. If a parameter from a

function block is displayed, then the function block must be scheduled (downloaded) in order for it to be displayed on the LCD. If a parameter from a different device is displayed, it must be linked to a block in the Rosemount 2051 transmitter with the LCD display and it must be downloaded. It can display any input or output parameter of any block in the Rosemount 2051. The first display is pre-configured to show the value of the transducer block of the Rosemount 2051. This value can be left or changed.

For each parameter n(n =1 - 4) displayed on the LCD there are several fields in the "Local Display" tab that must be setup.

1. The first parameter is called "BLOCK TAG_n," here you must enter the exact name of the block to be displayed. This must be the same name as the one that is stored in the device.

2. Then select "BLOCK TYPE_n". This is a drop down menu showing the selections available in the device. Select the disired block to be displayed, in the "BLK_TYPE_n" field.

3. Select "UNITS_TYPE_n". Select "Custom" in this parameter if bringing a value from outside the Rosemount 2051 device. "Auto" has only pressure units, which might or might not match the disired selection.

4. The next parameter is called "CUSTOM_TAG_n.” This is an optional selection in identifying which parameter, block or device to be viewed on the LCD. This can be any name up to five characters long.

5. Then select "PARAM_INDEX_n". This is a drop down menu and the selections available in the device will appear. Select which parameter is to be displayed, in the "PARAM_INDEX_n" field.

6. Select "CUSTOM_UNITS_n” if "Custom" was selected previously in the "UNITS_TYPE_n" field above. This is limited to five characters and is where the disired units you wish to be displayed are entered.

7. To display more than one parameter be sure and check the appropriate number of boxes in the "Display Parameter Select" field.

Warnings

Explosions can result in death or serious injury.

• Do not remove the transmitter covers in explosive environments when the circuit is

live.

• Transmitter covers must be fully engaged to meet explosion proof requirements.

• Before connecting a communicator in an explosive atmosphere, make sure the

instruments in the loop are installed in accordance with intrinsically safe or nonincendive field wiring practices.

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.

Performing a 'Restart with defaults' will set all function block information in the device to factory defaults. This includes the clearing of all function block links and schedule, as well as defaulting all Resource and Transducer Block user data.

July 2008

STATUS Along with the measured or calculated PV value, every FOUNDATION Fieldbus

block passes an additional parameter called STATUS. The PV and STATUS are passed from the Transducer Block to the Analog Input Block. The STATUS can be one of the following: GOOD, BAD, or UNCERTAIN. When there are no problems detected by the self-diagnostics of the block, the STATUS will be GOOD. If a problem occurs with the hardware in the device, or, the quality of the process variable is compromised for some reason, the STATUS will become either BAD or UNCERTAIN depending upon the nature of the problem. It is important that the Control Strategy that makes use of the Analog Input Block is configured to monitor the STATUS and take action where appropriate when the STATUS is no longer GOOD.

Master Reset Method Resource Block

To perform a master reset, run the Master Reset Method. If your system does not support methods, manually configure the Resource Block parameters listed below.

1. Set the RESTART to one of the options below:

• Run - Default State

• Resource - Not Used

• Defaults - Sets all device parameters to F

OUNDATION fieldbus default

values

• Processor - Does a software reset of the CPU

Simulation Simulate replaces the channel value coming from the Sensor Transducer

Block. For testing purposes, it is possible to manually drive the output of the Analog Input Block to a desired value. There are two ways to do this.

Manual Mode

To change only the OUT_VALUE and not the OUT_STATUS of the AI Block, place the TARGET MODE of the block to MANUAL. Then, change the OUT_VALUE to the desired value.

Simulate

1. If the SIMULATE switch is in the OFF position, move it to the ON position. If the SIMULATE jumper is already in the ON position, you must move it to off and place it back in the ON position.

Rosemount 2051

NOTE

As a safety measure, the switch must be reset every time power is interrupted to the device in order to enable SIMULATE. This prevents a device that is tested on the bench from getting installed in the process with SIMULATE still active.

2. To change both the OUT_VALUE and OUT_STATUS of the AI Block, set the TARGET MODE to AUTO.

3. Set SIMULATE_ENABLE_DISABLE to ‘Active’.

4. Enter the desired SIMULATE_VALUE to change the OUT_VALUE and SIMULATE_STATUS_QUALITY to change the OUT_STATUS.

• If errors occur when performing the above steps, be sure that the SIMULATE jumper has been reset after powering up the device.

3. Loosen the two captive screws that anchor the board to the housing. The electronics board is electrostatically sensitive; observe handling precautions for static-sensitive components. Use caution when removing the LCD as there is an electronic pin connector that interfaces between the LCD and electronics board. The two screws anchor the LCD display to the electronics board and the electronics board to the housing.

4. Using the two captive screws, slowly pull the electronics board out of the housing. The sensor module ribbon cable holds the electronics board to the housing. Disengage the ribbon cable by pushing the connector release.

1. Remove the electronics board. Refer to “Remove the Electronics Board” on page 5-10.

IMPORTANT

To prevent damage to the sensor module ribbon cable, disconnect it from the electronics board before you remove the sensor module from the electrical housing.

2. Carefully tuck the cable connector completely inside of the internal black cap.

NOTE

Do not remove the housing until after you tuck the cable connector completely inside of the internal black cap. The black cap protects the ribbon cable from damage that can occur when you rotate the housing.

3. Loosen the housing rotation set screw with a loosen one full turn.

4. Unscrew the module from the housing, making sure the black cap and sensor cable do not catch on the housing.

REASSEMBLY PROCEDURES

Attach the Electronics Board

1. Inspect all cover and housing (non-process wetted) O-rings and replace if necessary. Lightly grease with silicone lubricant to ensure a good seal.

2. Carefully tuck the cable connector completely inside the internal black cap. To do so, turn the black cap and cable counterclockwise one rotation to tighten the cable.

3. Lower the electronics housing onto the module. Guide the internal black cap and cable through the housing and into the external black cap.

4. Turn the module clockwise into the housing.

IMPORTANT

Make sure the sensor ribbon cable and internal black cap remain completely free of the housing as you rotate it. Damage can occur to the cable if the internal black cap and ribbon cable become hung up and rotate with the housing.

5. Thread the housing completely onto the sensor module. The housing must be no more than one full turn from flush with the sensor module to comply with explosion proof requirements.

6. Tighten the housing rotation set screw using a

1. Remove the cable connector from its position inside of the internal black cap and attach it to the electronics board.

2. Using the two captive screws as handles, insert the electronics board into the housing. Make sure the posts from the electronics housing properly engage the receptacles on the electronics board. Do not force. The electronics board should slide gently on the connections.

3. Tighten the captive mounting screws.

4. Replace the electronics housing cover. The transmitter covers must be engaged metal-to-metal to ensure a proper seal and to meet Explosion-Proof requirements.

/64-inch hex wrench.

Install the Terminal Block 1. Gently slide the terminal block into place, making sure the two posts from

the electronics housing properly engage the receptacles on the terminal block.

2. Tighten the captive screws.

3. Replace the electronics housing cover. The transmitter covers must be fully engaged to meet Explosion-Proof requirements.

Reassemble the 2051C Process Flange

1. Inspect the sensor module PTFE o-rings. Undamaged o-rings may be reused. Replace o-rings that show any signs of damage, such as nicks, cuts, or general wear.

NOTE

If you are replacing the o-rings, be careful not to scratch the o-ring grooves or the surface of the isolating diaphragm when removing the damaged o-rings.

2. Install the process connection. Possible options include:

Reference Manual

00809-0200-4101, Rev AA

July 2008

a. Coplanar Process Flange:

• Hold the process flange in place by installing the two alignment screws to finger tightness (screws are not pressure retaining). Do not overtighten as this will affect module-to-flange alignment.

• Install the four 1.75-in. flange bolts by finger tightening them to the flange.

b. Coplanar Process Flange with Flange Adapters:

• Hold the process flange in place by installing the two alignment screws to finger tightness (screws are not pressure retaining). Do not overtighten as this will affect module-to-flange alignment.

• Hold the flange adapters and adapter o-rings in place while installing the four configurations, use four 2.88-in. bolts. For gage pressure configurations, use two 2.88-in. bolts and two 1.75-in. bolts.

c. Manifold:

• Contact the manifold manufacturer for the appropriate bolts and procedures.

3. Tighten the bolts to the initial torque value using a crossed pattern. See Table 5-11 for appropriate torque values.

NOTE

If you replaced the PTFE sensor module o-rings, re-torque the flange bolts after installation to compensate for cold flow.

NOTE

After replacing o-rings on Range 1 transmitters and re-installing the process flange, expose the transmitter to a temperature of 185 °F (85 °C) for two hours. Then re-tighten the flange bolts in a cross pattern, and again expose the transmitter to a temperature of 185 °F (85 °C) for two hours before calibration.

1. Apply sealing tape to the threads on the seat. Starting at the base of the valve with the threaded end pointing toward the installer, apply two clockwise turns of sealing tape.

2. Tighten the drain/vent valve to 250 in-lb. (28.25 N-m).

3. Take care to place the opening on the valve so that process fluid will drain toward the ground and away from human contact when the valve is opened.

Failure Mode Alarm If self-diagnostics detect a sensor or microprocessor failure, the analog signal

is driven either high or low to alert the user. High or low failure mode is user-selectable with a jumper on the transmitter. The values to which the transmitter drives its output in failure mode depend on whether it is factory-configured to standard or NAMUR-compliant operation. The values for each are as follows:

Standard Operation Output Code Linear Output Fail High Fail Low

A3.9 ≤ I ≤ 20.8 I ≥ 21.75 mA I ≤ 3.75 mA M 0.97 ≤ V ≤ 5.2 V ≥ 5.4 V V ≤ 0.95V
