INSTALLATION PROCEDURES

For dimensional drawing information refer to Appendix A: Reference Data.

Electronics Housing

Provide 0.75 inches (19 mm) of clearance for units without an LCD display. Three inches of clearance is required for cover removal if a meter is installed.

Cover Installation

Always ensure a proper seal by installing the electronics housing cover so the o-ring is engaged. Use Rosemount O-rings.

Mount the Transmitter The Rosemount 4500 is designed to be mounted directly to a process pipe or

vessel using a standard sanitary fitting. The transmitter is available with either a 1.5 or 2-inch Tri-Clamp

When installing the transmitter to the sanitary fitting it is important to use the proper sanitary clamp and gasket (user-supplied). Check the clamp and gasket specifications before installing. Refer to Table 2-2 for a list of standard sanitary clamps, their respective maximum pressure ranges, and the recommended torque to be applied when mounting.

NOTE

Sensor burst pressure limits may be less than clamp pressure limits.

NOTE

Most transmitters are calibrated in the vertical position. Mounting the transmitter in any other position will shift the zero point to the equivalent amount of liquid head caused by the varied mounting position. To reset zero point, refer to “Sensor Trim” on page 4-5.

Set Switches Security (Write Protect)

Changes can be prevented to the transmitter configuration data with the write protection switches on the optional LCD or the switches on the optional LOI board. Position the switch in the “ON” position to prevent change of configuration data.

If the transmitter write protection switch 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.

To make connections, perform the following procedure:

1. Remove the housing cover.

2. Connect the positive lead to the terminal marked (+) and the negative lead to the terminal marked (pwr/comm –).

3. Tighten cord grip to avoid moisture accumulation in the terminal compartment.

Signal Wiring Grounding

Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical equipment. Ground the signal wiring at any one point on the signal loop, or leave it ungrounded. The negative terminal of the power supply is a recommended grounding point.

Power Supply 4–20 mA Transmitters

The dc power supply should provide power with less than two percent ripple. Total resistance load is the sum of resistance from signal leads and the load resistance of the controller, indicator, and related pieces. Note that the resistance of intrinsic safety barriers, if used, must be included.

See load limitations in Section A: Reference Data.

NOTE

A minimum loop resistance of 250 ohms is required to communicate with a HART Communicator. If a single power supply is used to power more than one 4500 transmitter, the power supply used and circuitry common to the transmitters should not have more than 20 ohms of impedance at 1200 Hz.

Grounding 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 electronics housing. The screw is identified by a ground symbol ( ), and is standard on all 4500 transmitters.

COMMISSIONING ON THE BENCH WITH HART

Setting the Loop to Manual

Commissioning consists of testing the transmitter and verifying transmitter configuration data. 4500 transmitters can be commissioned either before or after installation. Commissioning the transmitter on the bench before installation using a 375 Field Communicator or AMS ensures that all transmitter components are in working order.

To commission on the bench, connect the transmitter and the HART Communicator or AMS as shown in Figure 3-1. Make sure the instruments in the loop are installed according to intrinsically-safe or nonincendive field wiring practices before connecting in an explosive atmosphere. Connect HART Communicator leads at any termination point in the signal loop.

For 4–20 mA transmitters, the power supply must provide 11.25 to 30 V dc at the transmitter. To enable communication, a resistance of at least 250 ohms must be present between the HART Communicator loop connection and the power supply. Do not use inductive transient protectors with the 4500.

When using a HART Communicator, any configuration changes made must be sent to the transmitter by using the “Send” key (F2). AMS configuration changes are implemented when the “Apply” button is clicked.

For more information on the 375 Field Communicator see document 00809-0100-4276. AMS help can be found in the AMS on-line guides within the AMS system.

Whenever sending or requesting data that would disrupt the loop or change the output of the transmitter, set the process application loop to manual. The HART Communicator or AMS will prompt you to set the loop to manual when necessary. Acknowledging this prompt does not set the loop to manual. The prompt is only a reminder; set the loop to manual as a separate operation.

Wiring Diagrams Bench Hook-up

Connect the bench equipment as shown in Figure 3-1, and turn on the HART Communicator by pressing the ON/OFF key or log into AMS. The HART Communicator or AMS will search for a HART-compatible device and indicate when the connection is made. If the HART Communicator or AMS fail to connect, it indicates that no device was found. If this occurs, refer to Section 5: Troubleshooting.

CHECK OUTPUT Before performing other transmitter on-line operations, review the digital

output parameters to ensure that the transmitter is operating properly and is configured to the appropriate process variables.

Process Variables The process variables for the 4500 provide transmitter output, and are

continuously updated. The pressure reading in both engineering units and percent of range will continue to track with pressures outside of the defined range from the lower to the upper range limit of the Transmitter.

HART Communicator

The process variable menu displays the following process variables:

• Pressure

• Percent of range

• Analog output

• Sensor temperature

• Scaled Variable (SV)

NOTE

Regardless of the range points, the 4500 will measure and report all readings within the digital limits of the sensor. For example, if the 4 and 20 mA points are set to 0 and 100 psi, and the transmitter detects a pressure of 150 psi, it digitally outputs the 150 psi reading and a 150% of span reading. However, there may be up to ±5.0% error associated with output outside of the range points.

AMS

Right click on the device and select “Process Variables...” from the menu.The process variable screen displays the following process variables:

• Pressure

• Percent of range

• Analog output

• Sensor temperature

• Scaled Variable (SV)

Sensor Temperature The 4500 contains a temperature sensor near the pressure sensor in the

Rerange The Range Values command sets the 4 and 20 mA points (lower and upper

range values). In practice, you may reset the transmitter range values as often as necessary to reflect changing process conditions. Changing the lower or upper range point results in similar changes to the span.

NOTE

Transmitters are shipped from Rosemount Inc. fully calibrated per request or to the factory default of full scale (span = upper range limit.)

Use one of the methods below to rerange the transmitter. Each method is unique; examine all options closely before deciding which method works best for your process.

• Rerange with a HART Communicator only.

• Rerange with a pressure input source and a HART Communicator.

• Rerange with a pressure input source and the local zero and span buttons (option D1).

• Rerange with AMS only.

• Rerange with a pressure input source and AMS.

NOTE

If the transmitter security switch is ON, adjustments to the zero and span cannot be made. Refer to “Set Switches” on page 2-5 for security information.

Rerange with a HART Communicator Only

Fast Keys

The easiest way to rerange is to use the HART Communicator only. This method changes the values of the analog 4 and 20 mA points independently without a pressure input.

From the HOME screen, enter the fast key sequence for “Rerange with a Communicator Only.”

1. At “Keypad Input” select 1 and use the keypad to enter lower range value.

2. From “Keypad Input” select 2 and use the key pad to enter upper range value.

Rerange with a Pressure Input Source and HART Communicator

Fast Keys

Reranging using the HART Communicator and a pressure source or process pressure allows reranging the transmitter when specific 4 and 20 mA points are unknown.

1, 2, 3, 1, 1

1, 2, 3, 1, 2

NOTE

The span is maintained when the 4 mA point is set. The span changes when the 20 mA point is set. If the lower range point is set to a value that causes the upper range point to exceed the sensor limit, the upper range point is automatically set to the sensor limit, and the span is adjusted accordingly.

1. From the HOME screen, enter the fast key sequence for “Rerange with a Pressure Input Source and a HART Communicator” to configure lower and upper range values and follow the on-line instructions.

Rerange with a Pressure Input Source and the Local Zero and Span buttons (option D1)

The transmitter may be reranged using the local zero and span adjustments and a pressure source.

1. Using a pressure source with an accuracy three to ten times the desired calibrated accuracy, apply a pressure equivalent to the lower range value to the transmitter.

2. Push and hold the zero adjustment button for at least two seconds but no longer than ten seconds.

3. Apply a pressure equivalent to the upper range value to the transmitter.

DETAILED SETUP

Failure Mode Alarm and Saturation

4500 transmitters automatically and continuously perform self-diagnostic routines. If the self-diagnostic routines detect a failure, the transmitter drives the output to configured alarm values. The transmitter will also drive the output to configured saturation values if the applied pressure goes outside the 4-20 mA range values.

The transmitter will drive its output low or high based on the position of the failure mode alarm switch, see “Set Switches” on page 2-5.

NOTE

The failure mode alarm direction can also be configured using the HART Communicator or AMS.

4500 transmitters have three configurable options for failure mode alarm and saturation levels:

• Rosemount (Standard), see Table 3-1

• NAMUR, see Table 3-2

• Custom, see Table 3-3

Failure mode alarm and saturation levels can be configured using a HART Communicator or AMS, see “Alarm and Saturation Level Configuration” on page 3-12. Per Table 3-3, custom alarm and saturation levels can be configured between 3.6 mA and 3.9 mA for low values and between 20.1 mA and 23 mA for high values. The following limitations exist for custom levels:

• Low alarm level must be less than the low saturation level

• High alarm level must be higher than the high saturation level

• High saturation level must not exceed 21.5 mA

• Alarm and saturation levels must be separated by at least 0.1 mA

Alarm Level Verification If the transmitter electronics board, Transmitter, or LCD display is repaired or

replaced, verify the transmitter alarm level before returning the transmitter to service. This feature is also useful in testing the reaction of the control system to a transmitter in an alarm state. To verify the transmitter alarm values, perform a loop test and set the transmitter output to the alarm value (see Tables 3-1 and 3-2 on page 3-12, and “Loop Test” on page 3-19).

Process Alerts Process alerts allow the user to configure the transmitter to output a HART

Fast Keys

Burst Mode When configured for burst mode, the 4500 provides faster digital

Fast Keys

communication from the transmitter to the control system by eliminating the time required for the control system to request information from the transmitter. Burst mode is compatible with the analog signal. Because the HART protocol features simultaneous digital and analog data transmission, the analog value can drive other equipment in the loop while the control system is receiving the digital information. Burst mode applies only to the transmission of dynamic data (pressure and temperature in engineering units, pressure in percent of range, and/or analog output), and does not affect the way other transmitter data is accessed.

Access to information other than dynamic transmitter data is obtained through the normal poll/response method of HART communication. A HART Communicator, AMS or the control system may request any of the information that is normally available while the transmitter is in burst mode. Between each message sent by the transmitter, a short pause allows the HART Communicator, AMS or a control system to initiate a request. The transmitter will receive the request, process the response message, and then continue “bursting” the data approximately three times per second.

MULTIDROP COMMUNICATION

Figure 3-3. Typical Multidrop Network

Multidropping transmitters refers to the connection of several transmitters to a single communications transmission line. Communication between the host and the transmitters takes place digitally with the analog output of the transmitters deactivated. Up to fifteen transmitters can be connected on a single twisted pair of wires, or over leased phone lines.

Multidrop installation requires consideration of the update rate necessary from each transmitter, the combination of transmitter models, and the length of the transmission line. Communication with transmitters can be accomplished with Bell 202 modems and a host implementing HART protocol. Each transmitter is identified by a unique address (1–15) and responds to the commands defined in the HART protocol. HART Communicators and AMS can test, configure, and format a multidropped transmitter the same way as a transmitter in a standard point-to-point installation.

Figure 3-3 shows a typical multidrop network. This figure is not intended as an installation diagram.

NOTE

A transmitter in multidrop mode has the analog output fixed at 4 mA. If a display is installed to a transmitter in multidrop mode, it will alternate the display between “current fixed” and the specified meter output(s).

The 4500 is set to address zero (0) at the factory, which allows operation in the standard point-to-point manner with a 4–20 mA output signal. To activate multidrop communication, the transmitter address must be changed to a number from 1 to 15. This change deactivates the 4–20 mA analog output, sending it to 4 mA. It also disables the failure mode alarm signal, which is controlled by the upscale/downscale switch position. Failure signals in multidropped transmitters are communicated through HART messages.

Section 4 Operation and Maintenance

Calibration for HART Protocol . . . . . . . . . . . . . . . . . . . . . . page 4-1

OVERVIEW This section contains information on commissioning and operating 4500

Pressure Transmitters. Tasks that should be performed on the bench prior to installation are explained in this section.

CALIBRATION FOR HART PROTOCOL

Calibrating a 4500 transmitter may include the following procedures:

• Rerange: Sets the 4 and 20 mA points at required pressures.

• Sensor Trim: Adjusts the position of the factory characterization curve to optimize performance over a specified pressure range, or to adjust for mounting effects.

• Analog Output Trim: Adjusts the analog output to match the plant standard or the control loop.

The 4500 Transmitter uses a microprocessor that contains information about the sensor’s specific characteristics in response to pressure and temperature inputs. A smart transmitter compensates for these sensor variations. The process of generating the sensor performance profile is called factory characterization. Factory characterization also provides the ability to readjust the 4 and 20 mA points without applying pressure to the transmitter.

Trim and rerange functions are also distinct and different. Reranging sets the analog output to the selected upper and lower range points and can be done with or without an applied pressure. Reranging does not change the factory characterization curve stored in the microprocessor. Sensor trimming requires an accurate pressure input and improves compensation by adjusting the position of the factory characterization curve to optimize performance over a specific pressure range.

NOTE

Sensor trimming adjusts the position of the factory characterization curve. It is possible to degrade performance of the transmitter if the trim is done improperly or with inaccurate equipment.

Figure 4-1 on page 4-3 illustrates 4500 transmitter data flow. Data flow can be summarized in four major steps:

4-2

1. A change in pressure is measured by a change in the sensor output (Sensor Signal).

2. The sensor signal is converted to a digital format that is understood by the microprocessor (Analog-to-Digital Signal Conversion).

3. Corrections are performed in the microprocessor to obtain a digital representation of the process input (Digital PV).

4. The Digital PV is converted to an analog value (Digital-to-Analog Signal Conversion).

Choosing a Trim Procedure

To decide which trim procedure to use, you must first determine whether the analog-to-digital section or the digital-to-analog section of the transmitter electronics need calibration. Refer to Figure 4-1 and perform the following procedure:

1. Connect a pressure source, a HART Communicator or AMS, and a digital readout device to the transmitter.

2. Establish communication between the transmitter and the HART Communicator.

3. Apply pressure equal to the upper range point pressure.

4. Compare the applied pressure to the Process Variable (PV) line on the HART Communicator On-line Menu or the Primary Variables screen in AMS.

a. If the PV reading does not match the applied pressure (with

high-accuracy test equipment), perform a sensor trim.

5. Compare the Analog Output (AO) line, on the HART Communicator or AMS, to the digital readout device.

a. If the AO reading does not match the digital readout device (with

high-accuracy test equipment), perform an output trim.

Sensor Trim Trim the sensor using either full or zero trim functions. Trim functions vary in

complexity and are application-dependent. Both trim functions alter the transmitter’s interpretation of the input signal.

Zero trim is a single-point adjustment. It is useful for compensating for mounting position effects and is most effective when performed with the transmitter installed in its final mounting position. Since this correction maintains the slope of the characterization curve, it should not be used in place of a full trim over the full sensor range.

When performing a zero trim, ensure that the equalizing valve is open and all wet legs are filled to the correct levels.

NOTE

Do not perform a zero trim on 4500 Absolute pressure transmitters. Zero trim is zero based, and absolute pressure transmitters reference absolute zero. To correct mounting position effects on a 4500 Absolute Pressure Transmitter, perform a low trim within the full sensor trim function. The low trim function provides a “zero” correction similar to the zero trim function, but it does not require zero-based input.

Full trim is a two-point sensor calibration where two end-point pressures are applied, and all output is linearized between them. Always adjust the low trim value first to establish the correct offset. Adjustment of the high trim value provides a slope correction to the characterization curve based on the low trim value. The factory-established characterization curve is not changed by this procedure. The trim values allow you to optimize performance over your specified measuring range at the calibration temperature.

Diagnostic Messages In addition to output, the LCD display displays abbreviated operation, error,

and warning messages for troubleshooting. Messages appear according to their priority; normal operating messages appear last. To determine the cause of a message, use a HART Communicator or AMS to further interrogate the transmitter. A description of each LCD diagnostic message follows.

Error Indicator

An error indicator message appears on the LCD display to warn of serious problems affecting the operation of the transmitter. The meter displays an error message until the error condition is corrected, and analog output is driven to the specified alarm level. No other transmitter information is displayed during an alarm condition.

FAIL MODULE

The transmitter is malfunctioning. Possible sources of problems include:

• Pressure or temperature updates are not being received in the Transmitter.

• A non-volatile memory fault that will affect transmitter operation has been detected in the module by the memory verification routine.

Some non-volatile memory faults are user-repairable. Use a HART Communicator or AMS to diagnose the error and determine if it is repairable. Any error message that ends in “Factory” is not repairable.

FAIL CONFIG

A memory fault has been detected in a location that could effect transmitter operation, and is user-accessible. To correct this problem, use a HART Communicator or AMS to interrogate and reconfigure the appropriate portion of the transmitter memory.

Warnings

Warnings appear on the LCD display to alert you of user-repairable problems with the transmitter, or current transmitter operations. Warnings appear alternately with other transmitter information until the warning condition is corrected or the transmitter completes the operation that warrants the warning message.

PV LIMIT

4-10

The process variable read by the transmitter is outside of the transmitter’s range.

Page 51

Reference Manual

00809-0100-4027, Rev AA December 2005

Rosemount 4500

NONPV LIMIT

A secondary variable read by the transmitter is outside of the transmitter’s range.

CURR SAT

The pressure read by the module is outside of the specified range, and the analog output has been driven to saturation levels.

LOOP TEST

A loop test is in progress. During a loop test or 4–20 mA trim, the analog output is set to a fixed value. The meter display alternates between the current selected in milliamps and “LOOP TEST.”

XMTR INFO

A non-volatile memory fault has been detected in the transmitter memory by the memory verification routine. The memory fault is in a location containing transmitter information. To correct this problem, use a HART Communicator or AMS to interrogate and reconfigure the appropriate portion of the transmitter memory. This warning does not effect the transmitter operation. Contact Rosemount Customer Central at 800-999-9307 if you need assistance.

PRESS ALERT

A HART alert when the process variable read by the transmitter is outside of the user set alert limits.

TEMP ALERT

A HART alert when the secondary temperature variable read by the transmitter is outside of the user set alert limits.

Operation

Normal operation messages appear on the LCD display to confirm actions or inform you of transmitter status. Operation messages are displayed with other transmitter information, and warrant no action to correct or alter the transmitter settings.

ZERO PASS

The zero value, set with the local zero adjustment button, has been accepted by the transmitter, and the output should change to 4 mA.

ZERO FAIL

The zero value, set with the local zero adjustment button, exceeds the maximum range down allowed for a particular range, or the pressure sensed by the transmitter exceeds the sensor limits.

SPAN PASS

The span value, set with the local span adjustment button, has been accepted by the transmitter, and the output should change to 20 mA.

4-11

December 2005

SPAN FAIL

The span value, set with the local span adjustment button, exceeds the maximum range down allowed for a particular range, or the pressure sensed by the transmitter exceeds the sensor limits.

KEYS DISABL

This message appears during reranging with the integral zero and span buttons and indicates that the transmitter local zero and span adjustments have been disabled. The adjustments have been disabled by software commands from the HART Communicator or AMS. Keys are not detected when write protect jumper is active. See “Security (Write Protect)” on page 2-5 for information on the software lockout.

STUCK KEY

The zero or span button is stuck in the depressed state or pushed too long.
