Introduction

INTRODUCTION

LD400 HART® is a Smart Pressure Transmitter for differential, absolute, gauge, level and flow

measurements.

 Diferential Transmitter – LD400D and LD400H

This model measures the differential pressure applied in the sensor. Normally, both sides of the sensor are connected to the process and if the selected output function is linear, the measurement is the differential pressure. If the selected output function is a square root, the measurement is a fluid flow.

 Flow Transmitter – LD400D and LD400H

The differential pressure is generated by an flow primary element and the square root function supplies the measurement flow.

 Gauge Pressure Transmitter – LD400M

This model has the Lower Side Input connected to a blind flange and open to atmosphere. Therefore, this model measures the pressure relative to atmosphere and the output function can be linear or linearized by the linearization table.

 Absolut Pressure Transmitter - LD400A

This model has the Low Side Input connected to a blind flange and it is open to atmosphere. Therefore, this model measures the pressure relative to local pressure and the output function can be linear or linearized by the linearization table.

 Level Transmitter – LD400L

This model is available as a flange mounted unit with a flush diaphragm for direct installation on vessels. Extended dia phragms are also available.

The LD400 series use HART configuration softwares or others supplier. The local adjustment is enable for all the LD400 series. With ma gne t ic to ol s i s possible to configure the zero and the span, to alter the measurement range, to alter the unit of measured pressure, to select the square root function, to operate the total ed value or in a control loop.

TRANSMITTER GENERAL VIEW

The LD400 HART® uses a highly proven technique for pressure measuring by capacitance reading. The block diagram of the LD400 HART

pressure transmitter is shown below.

In the cell center is the sensor diaphragm (1). This diaphragm flexes in response to the different pressures applied on the LOW and HIGH sides of the cell (PL and PH). These pressures are directly applied on the isolator diaphragms (2), whose function is to isolate the sensor process and supply high resistance against corrosion caused by process fluids. The pressure is transmitted directly to the sensor diaphragm through the filling fluid (3) and causes its deflection. The sensor diaphragm is a mobile electrode whose two metal surfaces (4) are stable electrodes. A deflection on the sensor diaphragm is read by the capacitance variation between both stable and mobile electrodes.

The resonance oscillator reads the capacitance variations betw een the mobile and the sta ble board s and generates a pressure output equivalent to the detected capacitance variation. This pressure value is informed in compliance with the transmitter communication protocol. As the conversion process does not involve an A/D converter, any errors or deviations are eliminated during the process. Temperature compensation is done by a sensor, which combined with a precision sensor, results in high accuracy and range.

The process variable, as well as the diagnostic monitoring and information, are supplied by the digital communication protocol. The LD400 is available in the HART® communication protocol.

Read carefully these instructions for better use of the LD400 HART®. Smar pressure transmitters are protected by American patents n. 6,433,791 and 6,621,443.

General

INSTALLATION

The overall accuracy of a flow, level, or pressure measurement depends on several variables. Although the transmitter has an outstanding performance, proper installation is essential to maximize its efficiency. Among all factors, which may affect transmitter accuracy, environmental conditions are the most difficult to control. There are, however, ways of reducing the effects of temperature, humidity and vibration.

The LD400 HART the factory, each transmitter is submitted to a temperature cycle, and the characteristics under different temperatures are recorded in the transmitter memory. At the field, this feature minimizes the temperature variation effect.

Putting the transmitter in areas protected from extreme environmental changes can minimize temperature fluctuation effects. In warm environments, the transmitter should be installed to avoid, as much as possible, direct exposure to the sun. Installation close to lines and vessels subjected to high temperatures should also be avoided.

Use longer sections of impulse piping between tap and transmitter whenever the process fluid is at high temperatures. Use of sunshades or heat shields to protect the transmitter from external heat sources should be considered, if necessary.

Humidity is fatal to electronic circuits. In areas subjected to high relative humidity, the O-rings for the electronic housing covers must be correctly placed and the covers must be completely closed by tighten them by hand until you feel the O-rings being compressed. Do not use tools to close the covers. Removal of the electronics cover in the field should be reduced to the minimum necessary, since each time it is removed; the circuits are exposed to the humidity.

The electronic circuit is protected by a humidity proof coating, but frequent exposures to humidity may affect the protection provided. It is also important to keep the covers tightened in place. Every time they are removed, the threads are exposed to corrosion, since painting cannot protect these parts. Sealing methods should be employed on conduit entering the transmitter.

Although the transmitter is virtually insensitive to vibration, installation close to pumps, turbines or other vibrating equipment should be avoided. If entirely innevitable, install the transmitter on a solid basis and use flexible vibration-proof hoses. Proper winterization (freeze protection) should be employed to prevent freezing within the measuring chamber, since this will result in an inoperative transmitter and could even damage the cell.

Mounting

The transmitter has been designed to be both rugged and lightweight at the same time. This makes its mounting easier. The mounting positions are shown in Figure 1.1 and 1.2. Existing standards for the manifolds have also been considered, and standard designs fits perfectly to the transmitter flanges

Should the process fluid contain solids in suspension, install valves or rod-out fittings regularly to clean out the pipes.

LD400 HART® – Operation and Maintenance Instruction Manual

The pipes should be internally cleaned by using steam or compressed air, or by draining the line with the process fluid, before such lines are connected to the transmitter (blow-down).

NOTE

Typical Installati on for HART® Protocol

Figures 1.10 and 1.11 show LD400 HART® wiring diagrams to work as transmitter and controller, respectively.

Figure 1.12 shows the LD400 HART maximum of 15 transmitters can be connected on the same line and that they should be connected in parallel. Take care to the power supply as well, when many transmitters are connected on the same line. The current through the 250 Ω resistor will be high causing a high voltage drop. Therefore make sure that the power supply voltage is sufficient.

For HART® transmitters to operate in multidrop mode each transmitter must be configured with a different identity Device ID. In addition, if the transmitter identification mode on the loop is done through the Command 0 address, the HART the (Command 11) Tag the Tags must be similar.

The Handheld Terminal can be connected to the communication terminals of the transmitter or at any point of the signal line by using the alligator clips. It is also recommended to ground the shield of shielded cables at only one end. The ungrounded end must be carefully isolated. On multidrop connections, the circuit loop integrity must be assured, with special care to prevent short-circuit between the circuit loop and the housing.

MAIN BOARD

However, should the differential pressure (ΔP) apply to the capacitive cell not deflect the sensing diaphragm beyond d/4, it is possible to assume ΔP as proportional to Δd:

By developing the expression:

(4)

It follows that:

(5)

As the distance (d) between the fixed plates CH and CL is constant, it is possible to conclude that the expression (CL - CH)/(CL + CH) is proportional to Δd and, therefore, to the differential pressure to be measured.

Thus it is possible to conclude that the capacitive cell is a pressure sensor formed by two capacitors whose capacitances vary according to the applied differential pressure.

Funcional Description – Hardware

Refer to the block diagram Figure 2.2. The function of each block is described below.

Figure 2.2 – LD400 HART® Block Diagram Hardware

Oscillator

This oscillator generates a frequency as a function of sensor capacitance.

Signal Isolator

The Control signals from the CPU are transferred through optical couplers, and the signal from the oscillator is transferred through a transformer.

2.2

EEPROM

Another EEPROM is located within the sensor assembly. It contains data pertaining to the sensor's characteristics at different pressures and temperatures. This characterization is done for each sensor at the factory.

Temperature Sensor

Temperature Sensor used to compensate temperature variations.

Functional Description

(CPU) Central Processing Unit and PROM The CPU is the intelligent portion of the transmitter, being responsible for the management and operation of all other blocks, linearization and communication. The program is stored in an external PROM. For temporary storage of data the CPU has an internal RAM. The data in the RAM is lost, if the power is switched off, although the CPU also has an internal nonvolatile EEPROM where data that must be retained is stored. Examples of such data are: calibration, configuration and identification data.

D/A Converter

It converts the digital data from the CPU to an analog signal with 14-bits resolution.

Output

It controls the current in the line feeding the transmitters. It acts as a variable resistive load whose value depends on the voltage from the D/A converter.

Modem

This system provides the data exchanged between the serve-master digital communications. The transmitter demodulates information from the current line, and after treating it adequately, modulates over the line the answer to be sent. A "1" is represented by 1200 Hz and "0" by 2200 Hz. The frequency signal is symmetrical and does not affect the DC-level of the 4-20 mA signals.

Power Supply

Power must be supplied to the transmitter circuit using the signal line (2-wire system). The transmitter quiescent consumption is 3.6 mA; during operation, consumption may be as high as 21 mA, depending on the measurement and sensor status. The LD400 HART

in the transmitter mode shows failure indication at 3.6 mA if configured for low signal failure; at 21 mA, if configured for high signal failure; 3.8 mA in the case of low saturation; 20.5 mA in the case of high saturation and measurements proportional to the applied pressure in the range between 3.8 mA and 20.5 mA. 4 mA corresponds to 0% of the working range and 20 mA to100% of the working range.

Display Controller

It receives the data from the CPU and actives the LCD segments. It also activates the back plane and the control signals for each segment.

Local Adjustment

Two switches on the main board are magnetically activated by inserting the magnetic screwdriver. Without mechanical or electrical contact they cannot be activated. See figure 2.3.

LD400 HART® – Operation and Maintenance Instructi on M anu al

Functional Descripti on – LD400 HART® Software

Refer to the block diagram Figure 2.3. The function of each block is described below.

Factory Characterization

The actual pressure from the capacitance and temperature readouts obtained from the sensor can be calculated by using the factory characterization data stored in the sensor EEPROM.

Pressure Trim

The values obtained by Zero Pressure TRIM and Upper Pressure TRIM may correct here the transmitter for long term drift or the shift in zero or upper pressure reading due to installation or over pressure.

User Linearization

The characterization TRIM points P1 - P5 can be used to complement the transmitter original characterization.

Digital Filter

The digital filter is a low pass filter with an adjustable time constant. It is used to smooth noisy signals. The Damping value is the time required for the output reaching 63.2% for a step input of 100%.

This value (in seconds) may be freely configured by the user.

Engineering

The pressure value normalized it is converted for the engineering unit, considering the unit of selected pressure and the Upper Range Limit (URL).

Calibration

The pressure value is calculated in percents taking in consideration the work range provided by the Lower Range Value (LRV) and the Upper Range Value (URV).

Function

Depending on the application, the transmitter output or controller PV may have the following characteristics according to the applied pressure: Linear (for pressure, different ial pre ssur e and lev el measurement); Square-root (for flow measurement with differential pressure producers) and Square-root of the Third and Fifth power (for flow measurements in open channels). The function is selected with FUNCTION.

Block PID

The PID Block does the control having the Setpoint (SP) and the Process Variable (PV) as input and the Manipulated Value (MV) as output.

Block PID: SP - Setpoint

It is the desired value in the process variable when the controller is activated. The operator in the \CONTR\INDIC option adjusts it.

Block PID: PID Algorithm

First, the error is calculated: PV-SP (DIRECT ACTION) or SP-PV (REVERSE ACTION), then the MV (manipulated value) is calculated, according to the algorithm of the PID. The PID output signal may follow a user-determi ned curv e, in up to 16 configurable points. If the table is enabled, there will be a display indication with the F(X) character

Block PID: Auto/Manual

The Auto/Manual mode is configured in CONTR/INDIC. With the PID in Manual, the MV can be adjusted by the user in the LOW LIMIT to HIGH LIMIT range in the CONTR/LIM-SEG option. The POWER-ON option is used here to determine in which mode the controller should be upon powering it on.

Block PID: Limits

This block makes sure that the MV does not go beyond its minimum and maximum limits as established by the HIGH-LIMIT and LOW-LIMIT. It also makes sure that the Rate-of-Change does not exceed the value set in OUT-CHG/S.

2.4

Functional Description

Block PID: Bumpless A/M

On the Manual mode, the PID algoritm uses the output values as a compensation to its proportional action so that the Manual to Automatic transition do not occur abruptly . Therefore, even if the transition occurs in the presence of a percent ERROR., the proportional action is nullified and the output is adjusted softly according to the integral action.

Block PID: Points Table PID

This block relates the output (4-20 mA or Process Variable) to the input (applied pressure) according to a look-up table from 2 to 16 points. The output is calculated by the interpolation of these points. The points are given in the function "TABLE POINTS" in percent of the range (X in percent of the output (Y

i). It may be used to linearize, e.g., a level measurement to volume or

i) and

mass. In flow measurement it can be used to correct varying Reynolds numbers.

Output

It calculates the current proportional to the process variable or manipulated variable to be transmitted on the 4-20 mA output depending on the configuration in OP-MODE. This block also contains the constant current function configured in OUTPUT. The output is physically limited to 3.6 to 21 mA.

Current Trim

The 4 mA TRIM and 20 mA TRIM adjustment is used to make the transmitter current comply with a current standard, should a deviation arise.

User Unit

It converts 0 and 100% of the process variable to the desired engineering unit readout available for display and communication. It is used, e.g., to get a volume or flow indication from a level or differential pressure measurement, respectively. A unit for the variable can also be selected.

Totalization

Used for flow application to totalize the accumulated flow since the last reset, the last reset, getting the volume or mass transferred. In the lack of power, the totalized value is saved and continues totalizing after its re-establishment.

Display

The two indications configured in the DISPLAY can be alternated.

General

CONFIGURATION

The LD4 00 HART features a measurement device can possibly have. Its digital communication protocol (HART) enables the instrument to be connected to a computer in order to be configured in a very simple and complete way. Such computers connected to the transmitters are called HOST computers. They can either be primary or Secondary Masters. Therefore, even the HART protocol, it is possible to work with up to two masters in a bus. The Primary HOST plays the supervisory role and the Secondary HOST plays the Configuration tool role.

The transmitters may be connected in a point-to-point or multidrop type network. In a point-to-point connection, the equipment must be in its "0" address so that the output current may be modulated in 4 to 20 mA, as per the measurement. In a multidrop network, if the devices are recognized by their addresses, the transmitters shall be configured with a network address between "1" and "15. In this case, the transmitter output current is kept constant, with a consumption of 4 mA each. If the acknowledgement mechanism is via Tag, the transmitter addresses may be "0" while their output current is still being controlled, even in a multidrop configuration.

In the case of the LD400 HART the HART

TRANSMITTER MODE - The "0" address causes the LD400 HART and addresses "1" through "15" place the LD400 HART® in the multidrop mode with current control.

CONTROLLER MODE - The LD400 HART® always controls the output current, in accordance with the value calculated for the Controlled Variable, regardless of its network address.

addressing is used as follows:

Intelligent Pressure Transmitter is a digital instrument with the most up-to-date

being a master-slave type of

, which can be configured both as Transmitter and as a Controller;

to control its output current

NOTE

the area shall be strictly observed. Therefore, the follow ing shall be che cke d:

Where:

Ca, La - Barrier Allowable Capacitance and Inductance; Ci

j, Lij - Non protected internal Capacitance/Inductance of transmitter j (j = up to 15);

Cc, Lc - Cable capacitance and Inductance; Voc - Barrier open circuit voltage;

sc - Barrier short circuit current;

j - Maximum allowable voltage to be applied to the instrument j;

Primary Variable Trim – Pressure

Pressure, defined as a Primary Variable, is determined from the sensor readout by means of a conversion method. Such a method uses parameters obtained during the fabrication process. They depend on the electric and mechanical characteristics of the sensor, and on the temperature change to which the sensor is submitted. These parameters are recorded in the sensor's EEPROM memory. When the sensor is connected to the transmitter, such information is made available to the transmitter microprocessor, which sets a relationship between the sensor signal and the measured pressure.

Sometimes, the pressure shown on the transmitter display is different from the applied pressure. This may be due to several reasons, among which the following:

 The transmitter mounting position;  The user pressure standard differs from the factory standard;  Sensor original characteristics shifted by overpressure, over temperature or by long-term

drift.

Configuration

NOTE

refers to a certain point of the tank or tap (wet leg). Such practice, however, is not recommended

The Pressure Trim, as described on this document, is the method used in order to adjust the measurement both in relation to the applied pressure and the user's pressure standard. The most common discrepancy found in transmitters is usually due to Zero displacement. This may be corrected by means of the zero trim or the lower trim.

There are four types of pressure trim available:

 LOWER TRIM: Is used to trim the reading at the lower range. The user informs the

transmitter the correct reading for the applied pressure via HART configuration tool.

NOTE

accuracy, the trim adjustment should be made in the lower and upper values of the operation range

For Absolute Pressur

 UPPER TRIM: Is used to trim the reading at the upper range. The user informs the

transmitter the correct reading for the applied pressure via HART configuration tool.

The upper pressure trim shall always be applied after the zero trim.

 ZERO TRIM: is similar to the LOWER TRIM, but is assumed that the applied pressure is

zero. The reading equal to zero must be active when the pressures of differential transmitter cameras are equalized or when a gage transmitter opens to atmosphere or when the absolute transmitter is applied to the vacuum. Therefore, the user does not need to enter with any value.

and make sure that you are working with a pressure standard with 0.03% accuracy or better, otherwise the transmitter accuracy will be seriously affected.

The transmitter presents a resolution that makes it possible to control currents as low as that data input consider values up to tenths of microamperes.

The pressure taps on the transmitter must be equalized when zero trim is applied.

 CHARACTERIZATION: this is used to correct any possible intrinsic non-linearity to the

conversion process. Characterization is done by means of a linearization table, with up to five points. The user shall apply pressure and use the HART configuration tools to inform the pressure value applied to each point of the table. In most cases, characterization is not required, due to the efficiency of the production process. The transmitter will display "CHAR", thus indicating that the characterization process has been activated. The LD400

is fitted with an internal feature to enable or disable the use of the Characterization

HART

Table.

The characterization trim changes the transmitter characteristics. Read the instructions carefully

Primary Variable Current Trim

When the microprocessor generates a 0% signal, the Digital to Analog converter and associated electronics are supposed to deliver a 4 mA output. If the signal is 100%, the output should be 20 mA.

There might be differences between the Smar current standards and your current plant Standard. In this case, the Current Trim adjustment shall be done with a precision ammeter as measurement reference.

Two Current Trim types are available:

 4 mA TRIM: this is used to adjust the output current value corresponding to 0% of the

measurement;

 20 mA TRIM: this is used to adjust the output current value corresponding to 100% of the

measurement;

The Current Trim shall be carried out as per the following procedure:

 Connect the transmitter to the precision ammeter;  Select one of the Trim types;  Wait a while for the current to stabilize and inform the transmitter the current readout of the

precision ammeter.

Temperature Trim

The LD400 HART located near the process plug board. Normally, this temperature is adjusted to the ambient temperature, during manufacturing. Is any deviation on the measuring is recorded; the Temperature Trim is done to correct it. Through a single calibration method, the LD400 HART® may adjust temperature Zero as well as Span. Whenever the Temperature Trim is applied at temperature over

C in relation to the last measuring; the LD400 HART® adjusts these two parameters

20 simultaneously.

transmitter monitors the temperature to be measured with the capacitive sensor

Transmitter Adjustment t o the Working Range

This function directly affects the transmitter 4-20 mA output. It is used to define the transmitter working range; in this document it is referred to as the transmitter calibration. The LD400 HART

4.6

transmitter includes two calibration features:

Configuration

Should the transmitter operate with a very small span, it will be extremely sensitive to pressure how small, will be amplified.

In most applications with wetted taps, indication is usually expressed as a percentage. Should Unit feature for such conversion.

 CALIBRATION WITH REFERENCE: this is used to adjust the transmitter working range,

using a pressure standard as reference;

 CALIBRATION WITHOUT REFERENCE: this is used to adjust the transmitter working

range, simply by having user-informed limit values.

Both calibration methods define the Working Range Upper and Lower values, in reference to some applied pressure or simply informed by entered values. CALIBRATION WITH REFERENCE differs from the Pressure Trim, since CALIBRATION WITH REFERENCE establishes a relationship between the applied pressure and the 4 to 20 mA signal, and the Pressure Trim is used to correct the measurement.

In the transmitter mode, the Lower Value always corresponds to 4 mA and the Upper Value to 20 mA. In the controller mode, the Lower Value corresponds to PV=0% and the Upper Value to PV=100%.

The calibration process calculates the LOWER and the UPPER values in a completely independent way. The adjustment of values does not affect one another. The following rules shall, however, be observed:

• The Lower and Upper values shall be within the range limited by the Minimum and Maximum Ranges supported by the transmitter. As a tolerance, values exceeding such limits by up to 24% are accepted, although with some accuracy degradation;

• The Working Range Span, determined by the difference between the Upper and Lower Values, shall be greater than the minimum span, defined by [Transmitter Range / (120) for models: D, M, H, A4, A5, and Transmitter Range / (2.5), (25), or (50) for A1, A2, and A3, respectively]. Values up to 0.75 of the minimum span are acceptable with slight accuracy degradation.

NOTE

variations. Keep in mind that the gain will be very high and that any pressure change, no matter

If it is necessary to perform a reverse calibration, that is, to work with an UPPER VALUE smaller than the LOWER VALUE, proceed as follows:

• Place the Lower Limit in a value as far as possible from the present Upper Value and from the new adjusted Upper value, observing the minimum span allowed. Adjust the Upper Value at the desired point and, then, adjust the Lower Value.

This type of calibration is intended to prevent the calibration from reaching, at any moment, values not compatible with the range. For example: lower value equals to upper value or separated by a value smaller than the minimum span.

This calibration procedure is also recommended for zero suppression or elevation in those cases where the instrument installation results in a residual measurement in relation to a certain reference. This is the specific case of the wetted tap.

NOTE

readout in engineering units with zero suppression be required, it is recommended to use the User

Engineering Unit Selection

Table 4.1 – Available Pressure Units

In applications where the LD400 HART® will be used to measure variables other than pressure or in the cases where a relative adjustment has been selected, the new unit may be displayed by means of the User Unit feature. This is the case of measurements such as level, volume, and flow rate or mass flow obtained indirectly from pressure measurements.

The User Unit is calculated adopting the working range limits as a reference, which is, defining a value corresponding to 0% and another corresponding to 100% of the measurement:

- 0% - Desired readout when the pressure is equal to the Lower Value (PV% = 0%, or transmitter mode output equal to 4 mA);

- 100% - Desired readout when the pressure is equal to the Upper Value (PV% = 100%, or transmitter mode output equal to 20 mA).

The user unit may be selected from a list of options included in the LD400 HART

. Table 4.2 makes it possible to associate the new measurement to the new unit so that all supervisory systems fitted the HART® protocol can access the special unit included in this table. The user will be responsible for the consistency of such information. The LD400 HART® does not verify if the values corresponding to the 0% and 100% inserted by the user are compatible with the selected unit.

Example: transmitter LD400 HART® is connected to a horizontal cylindrical tank (6 meters long and 2 meters in diameter), linearized for volume measurement using camber table data in its linearization table. Measurement is done at the high-pressure tap and the transmitter is located 250 mm below the support base. The fluid to be measured is water at 20 °C.

10 x. This function is used in flow measurement with, e.g., orifice or Venturi tube etc.

The Square Root has an adjustable cutoff point. Below this point the output is linear, if the cutoff mode is bumpless with the differential pressure as indicated by the Figure 4.4. If the cutoff mode is hard the output will be 0% below the cutoff point. The default value for Cutoff is 6% of ranged pressure input. The maximum value for cutoff is 100%. Cutoff is used to limit the high gain, which results from square root extraction on small values. This gives a more stable reading at low flows.

In order to find the square root, the LD400 HART® configurable parameters are: cutoff point defined at a certain pressure expressed as % and the cutoff mode, hard or bumpless.

In bumpless cutoff mode the gain below the cutoff point is given by the equation:

in both ways). This function is available for version 6.05 or above firmware. The measurement of the bidirectional flow is useful when it is needed to measure the flow in the

pipe in both directions. For example, in tank maneuvering there are several pipes where the direction of the fluid may vary. In this case, LD400 HART® has the bidirectional flow measurement function. This function treats the flow, no matter what its direction is, as if it were positive. Thus, it is possible to extract the square root and measure the bidirectional flow.

Table Points

If the option TABLE is selected, the output will follow a curve given in the option TABLE POINTS. If the user wants to have your 4-20 mA proportional to the fluid volume or mass inside a tank, he must transform the pressure measurement "X" into volume (or mass) "Y" using the tank strapping table, as the example shown in Table 4.3.

As shown on the previous example, the points may be freely distributed for any desired value of X. In order to achieve a better linearization, the distribution should be concentrated in the less linear parts of the measurement.

The LD400 HART® includes an internal feature to enable and disable the Linearization Table.

Totalization Configur a t ion

When the LD400 HART® works in flow applications it is often desirable to totalize the flow in order to know the accumulated volume or mass that has flown through the pipe/channel.

The totalizer integrates PV% over time: The totalizer integrates the PV% along time, working with a time scheduling based on seconds, as

WARNING

The total value is not lost with power drop.

The method uses such totalization and, through three parameters (MAXIMUM FLOWRATE, TOTAL INCREMENT and TOTAL UNIT), converts it to the user-defined totalizing unit:

 MAXIMUM FLOW RATE - this is the maximum flow rate expressed in volume or mass units per

second, corresponding to the measurement (PV%=100%). For example: m3/s, bbl/s, kg/s, lb/s;

 TOTALIZATION INCREMENT - this is used to convert the flow rate base unit into a multiple unit

of mass or volume. For example, a flow rate totalized in gallons/s may be converted to a volume in m3; a mass flow rate of g/s may be converted to kilos, etc.

 TOTALIZATION UNIT - this is the engineering unit. It shall be associated to the totalized value.

It may be a standard unit or a special unit with up to five characters.

WARNING

To configure any these parameters, the totalizer should be disable.

The largest totalized value is 99.999.999 totalizing units. When the totalization is displayed, the most significant part is shown on the numeric field, and the less significant part is shown on the alphanumeric field. Figure 4.5 shows a typical display indication.

NOTE

F(t) indication is activated every time the totalized value is shown on the digital display.

The following services are associated with the Totalizer:

 INITIALIZATION - Totalization is reinitialized from value "0";  ENABLING/DISABLING - this allows the totalization function to be enabled or disabled.

Example: A differential pressure of 0 - 20 inH In CONF set Lower = 0 inH

O and Upper = 20 inH2O.

O represents a flow of 0 - 6800 dm³/minute.

In order to adjust the MAX._FLOW, the maximum flow must be converted to cubic decimeters per second: 6800 / 60 = 113.3 dm

/s.

The selection of the totalization unit (U_TOTAL) is made in function of the maximum flow and the minimum time allowable for the counter overrun, i.e., the time required for the totalization to reach

99.999.999. In the example, if U_TOTAL = 1, the totalization increment is 1 dm

. The time required for the

overrun with maximum flow is 245 hours, 10 minutes and 12.5 seconds. On the other hand, in case a TOTALIZATION INCREMENT equal to 10 is used, the totalized unit

will be deciliter (dal) and the totalizer will receive one increment at every 10 dm maximum flow rate (113.3 dm

/s), the totalizer will reach its maximum value and return to zero in10

All these parameters accept zero as input. Such value simply nullifies the corresponding PID control actions.

PID Controller Configura t ion

The LD400 HART® may be factory -configured to work as Transmitter only or as Transmitter / Controller. In case the LD400 HART change its operation mode at any time simply by configuring an internal status variable.

As a PID Controller, the LD400 HART® may run a PID type control algorithm, where its 4 to 20 mA will represent the status of the Manipulated variable (MV). In such a mode, output is 4 mA when the MV = 0% and 20 mA when MV = 100%.

The PID implementation algorithm is:

MV = Kp (e + 1/Tr ∫ e dt + Td dPV/dt )

Where:

e(t) = PV-SP (direct) SP-PV (reverse) SP = Setpoint PV = Process Variable (Pressure, Level, Flow, etc.) Kp = Proportional Gain Tr = Integration Time Td = Derivative Time MV = Manipulated Variable (output)

The three configuration groups below are pertinent to the PID controller:

SAFETY LIMITS - this group enables the configuration of: Safety Output, Output Rate and Output Lower and Upper Limits.

The Safety Output defines the value of the output in the case of equipment failure. Output Rate is the maximum variation Rate allowed for the output, expressed in %/s. The Lower and Upper Limits define the output range.

TUNING - this group enables the PID tuning to be performed. The following parameters may be adjusted: Kp, Tr and Td.

Parameter Kp is the proportional gain (not the proportional band) that controls the PID proportional action. It may be adjusted from 0 to 100.

Parameter Tr is the integral time that controls the PID integral action. It may be adjusted from 0 to 999 minutes per repetition.

Parameter Td is the derivative time controlling the PID derivative action. It may be adjusted from 0 to 999 seconds.

The Control Action Mode enables the selection of the desired output action: direct or reverse. In direct action, a PV increase causes an output increase; in reverse action, a PV increase causes an output decrease.

When the Setpoint Tracking mode is enabled, it is possible for the Setpoint to follow the PV while in Manual Control. Thus, when control passes to Auto, the Setpoint value will be that of the last PV prior to the switching.

When the PID is enabled, the Power On mode allows the adjustment of the mode in which the PID controls shall return after a power failure: Manual mode, Automatic mode or the last mode prior to the power failure.

TABLE – If the table option is selected, the MV output will follow a curve according to the values typed in the LD400 HART

characterization table. The points can freely be configured as

percentage values. For a better linearization, it is recommendable that the points are the closest possible, in the less linear regions of the curve. The LD400 HART enable and disable the characterization table of the MV output of the PID.

Equipment Configura t ion

The LD400 HART® enables the configuration not only of its operational services, but of the instrument itself. This group includes services related to: Input Filter, Burnout, Addressing, Display Indication and Passwords.

 INPUT FILTER - The Input Filter, also referenced to as damping, is a first class digital filter

implemented by the firmware. User configurable from any value higher than zero seconds in addition to intrinsic sensor response time (0.2 s) (via digital communication). The transmitter mechanical damping is 0.2 seconds.

 BURN OUT - The output current may be programmed to go to the maximum limit of 21 mA (Full

Scale) or to the minimum limit of 3.6 mA in case of transmitter failure. Configuring the BURNOUT parameter for Upper or Lower may do this. The BURNOUT configuration is only valid in the transmitter mode. When a failure occurs in the PID mode, the output is driven to a safety Output value, between 3.8 and 20.5 mA.

 ADDRESSING - The L D400 HART® includes a variable to define the equipment address in a

HART network. Addresses may go from value "0" to "15"; addresses from "1" to "15" are specific addresses for multidrop connections. This means that, in a multidrop configuration, the

LD400 HART

mode, is altered to another value than "0" (this does not happen when the LD400 HART® is

will display the message MDROP for addresses "1" to "15".

NOTE

Configuration

The LD400 HART® is factory-configured with address "0".

 DISPLAY INDICATION - the LD4 00 HART® digital display is comprised of three distinct fields:

an information field with icons indicating the active configuration status, a 4 ½ digit numeric field for value indication and a 5 digit alphanumeric field for units and status information.

The LD400 HART® may work with up to two display configurations to be alternately displayed at 2 second intervals. Parameters that may be selected for visualization are those listed on Table 4.4, below.

ER% (*) Error in percentage (PV% - SP %).

Table 4.4– Variables for Display Indication

NOTE

 PASSWORDS - this service enables the user to modify the operation passwords used in the

LD400 HART®. Each password defines the access for a priority level (1 to 3); such configuration is stored in the LD400 HART

EEPROM. Password Level 3 is hierarchically superior to

password level 2, which is superior to level 1.

The Magnetic Tool

PROGRAMMING USING LOCAL ADJUSTMENT

With the Magnetic Tool it is possible to configure locally the LD400 HART additional configurators in many basic applications.

There are two ways to adjust the LD400 HART Table 5.1):

locally according to the jumper configuration (see

 Simple Local Adjustment 

Complete Local Adjustment

For the configuration with the magnetic tool to be possible:

 The display must be connected;  The writing protection jumper must be disabled;  The local adjustment jumper must be enabled on simple mode or complete mode.

See on Figure 5.1 the jumper positions for Local Adjustment and Writing Protection on the main board. If the option chosen be for the Complete Adjustment, with a disabled writing protection and w ithout the display connected, the transmitter will redirect automatically the local adjustment for Simple mode. This happens because the Complete Local Adjustment needs an interaction with the display, and Simple Local Adjustment doesn’t.

Local Adjustment In the transmitter mode, the simple local adjustment is used for Zero and Span Calibration.

On the other hand, the Complete Local Adjustment makes possible to use the transmitter for sever al operations, both for control and for configuration.

and eliminate the need for

To configure the Local Adjustment, set the main board jumpers as shown on Table 5.1.

Programming Using Local Adjustment

Under the identification plate, the transmitter has two orifices where the magnetic tool is inserted t o set the Local Adjustment. See Figure 5.2.

Figure 5.2 – Zero and Span Local Adjustment

The holes are marked with Z ( Zero) and S (Span) and from now on will be simply described as (Z) and (S), respectively. Table 5.2 shows the action performed by the magnetic tool while inserted in (Z) and (S) in accordance with the selected adjustment type.

Browsing the functions and their branches works as follows:

 Inserting the handle of the magnetic tool in (Z), the transmitter passes from the normal

measurement state to the transmitter configuration state. The transmitter software automatically starts to display the available functions in a cyclic routine. The grou p of funct ions displayed depends on the mode selected for the LD400 HART Controller.

 In order to reach the desired option, browse the options, wait until they are displayed and move

the magnetic tool from (Z) to (S). Refer to Figure 5.3 – Local Adjustment Programming Tr ee, in order to know the position of the desired option. By placing the magnetic tool once agai n in (Z), it is possible to browse other options within this new branch.

 The procedure to reach the desired option is similar to the one described on the previous i tem,

for the whole hierarchical level of the programming tree.

The performance form of the Simple Local Adjustment is how it proceeds:

 Zero Calibration: when inserting the magnetic tool in the (Z) hole, the measured pressure w ill

be equivalent to the 4 mA current pressure;

 Span Calibration: when inserting the magnetic tool in the (S) hole, the measured pressure will

be equivalent to the 20 mA current pressure.

For adequate calibration, notice the minimum span for each measu ring rang e and types as defined on

Zero calibration with reference shall be done as follows:

Apply the Lower Value pressure; Wait for the pressure to stabilize; Insert the magnetic tool in the ZERO adjustment holes. (See Figure 5.2); Wait 2 seconds and the transmitter should be reading 4 mA; Remove the tool.

Zero calibration with reference does not affect the span. In order to change the span, the following procedure shall be observed:

Apply the Upper Value pressure; Wait for the pressure to stabilize; Insert the magnetic tool in the SPAN adjustment hole (S); Wait 2 seconds. The transmitter should be reading 20 mA.; Remove the tool.

Zero adjustment causes zero a new upper value (URV) is calculated in accordance with the effective span. In case the resulting URV is higher than the Upper Limit Value (URL), the URV w ill be limited to the URL value, and the span will be automatically affected.

Simulation [SIMUL]

When programming using local adjustment, the transmitter will not prompt "Control lo op should be in manual!" as it does when using the HART

configurator for programming. Therefore it is a good idea,

configuration is completed.

The main branch starts at the “SIMUL” option.

SIMULATION (SIMUL) – Simulation loop test current. Options: 4 mA, 8 mA, 12 mA, 16 mA or 20 mA. RANGE (RANGE) – It is the option allows operation range zero, span, lower and upper values

calibration. TRIM (TRIM) – It is the option used to calibrate the "with reference" characterization and the digital

reading. CONFIGURATION (CONF) – Is the option where the output and display related parameters are

configured: damping, function, display and address. OPERATION (OPER) – Is the option where the operation related parameters of the controller are

configured: Reset, Auto/Manual, Setpoint and Manual output. QUIT - Is the option used to go back to normal monitoring mode.

This operation simulates the output current for the Loop test. Optional values to be simulated are 4 mA, 8 mA, 12 mA, 16 mA or 20 mA.

MAINTENANCE

General

Below, there are some important maintenance procedures that should be followed in order to have safer plant and easy maintenance.

In general, it is recommended that end users do not try to repair printed circuit boards. Spare circuit boards may be ordered from SMAR whenever necessary.

The sensor has been designed to operate for many years without malfunctions. Should the process application require periodic cleaning of the transmitter, the flanges may be easily removed and reinstalled.

Should the sensor eventually require maintenance, it may not be changed on the field. In this case, the possibly damaged sensor should be returned to SMAR f or evaluation and, if necessary, repair. Refer to the "Returning Materials" item at the end of this Section.

Diagnostic using Configurat ion Tool

Should any problem be noticed regarding the transmitter output, the configurator can be used to verify what is the problem (see Table 6.1).

The configurator should be connected to the transmitter according to the wiring diagram shown on Section 1, Figures 1.7, 1.8 and 1.9.

Error Messages

When communicating using the CONFIGURATOR the user will be informed about any problem found by the transmitter self-diagnostics.

Disassembly Procedure

6.4

Figure 6.1 shows a transmitter exploded view and will help you to visualize the following.

Sensor

In order to have access to the sensor (29) for cleaning purposes, the transmitter should be removed from its process connections. The transmitter should be isolated from the process by means of manifolds or valves; then, the drain (16) must be opened to vent any remaining pressure.

After this, the transmitter may be removed from the standpipe. The flange bolts (17) may now be loosened counterclockwise, one at a time. After removing bolts and flanges (18), the isolating diaphragms will be easily accessible for cleaning.

Cleaning should be done carefully in order to avoid damaging the delicate isolating diaphragms. Use of a soft cloth and a nonacid solution is recommended.

The oscillator circuit is part of the sensor. If the former is replaced, the latter should also be

Maintenance

replaced. The oscillating circuit is a part of the sensor and the replacement of one implies replacing the other. To remove the sensor from the electronic housing, the electrical connections (in the field terminal side) and the main board connector must be disconnected.

Loosen the hex screw (7) and carefully unscrew the electronic housing from the sensor, observing if the flat cable is not excessively twisted.

WARNING

To avoid damage do not rotate the electronic housing more than 270º without disconnecting the electronic circuit from the sensor and from the power supply. See Figure 6.2.

Electronic Circuit

To remove the circuit board (6), loosen the two screws (5).

The board has CMOS components, which may be damaged by electrostatic discharges. Make

circuit boards should be stored in electric-charge proof packages.

Pull the main board out of the housing and disconnect the power supply and the sensor connectors.

Reassembly Procedure

Do not assemble with power on.

Sensor

When mounting the sensor (29), make use of a new set of gaskets (20 and 21) com pat ible with th e process fluid. The bolts, nuts, flanges and other parts should be inspected for corrosion or other eventual damage. Damaged parts should be replaced.

The O-rings should be lightly lubricated with silicon oil before they are fitted into place. Use halogen grease on applications having inert filling fluid. The flanges must be positioned on a flat surface. Insert the gaskets and Backup (19) (only for high pressure) in the flange according to figure 6.1. Set the four bolts (17) and tighten the nuts (30) initially by hand while keeping the flanges parallel through the whole mounting and finalize with an adequate tool.

High pressure transmitters A5, A6, M5, M6 and High static pressure H2, H3, H4, H5 and the sensors with tantalum diaphragm that use Buna-N or Viton O-ring must use a metallic backup Ring (19) to prevent extrusion of O-ring. Do not use the backup O-Ring when using Teflon ORings or flanges that have KYNAR ins ets (PVDF).

Don’t bendin g the backup ring and inspect it for knits cuts etc. Be careful when mounting it. The flat side, which shines more than the beveled side, shall be mounted against the O-ring (Figure

6.3). For these models use a spring lock ring when using a Teflon ring. See the spare parts list for the

Figure 6.2– Sensor Rotation Stopper

O-RINGS AND BACKUP RINGS FOR HIGH PRESSURE

LD400 HART® – Operation and Maintenance Instructi on Manual

Figure 6.3 – Backup Ring Mounting

Procedure for tightening the flange screws

 Tighten one nut till the flange seats;  Tighten the nut diagonally across with a torque of 2.5 to 3 Kgfm;  Tighten the first nut with the same torque;  Verify the flanges alignment;  Check torque on the four bolts.

Should the adapters (27) be removed, it is recommended to replace gaskets (26) and to connect the adapters to the process flanges before coupling them to the sensor. Optimum torque is 2.5 to 3 Kgfm.

The fitting of the sensor must be done with the main board out of the electronic housing. Mount the sensor to the housing turning it clockwise until it stops. Then turn it counterclockwise until the cover

(1) is parallel to the process flange (18). Tighten the screw (7) to lock the body to the sensor.

Electronic Circuit

Plug sensor connector and power supply connector to main board. If there is a display, attach it to the main board by means of 4 screws (3). The display can be installed in any of the 4 possible positions (See Figure 6.4). The”▲” mark indicates up position.

Pass the screws (5) through the main board holes (6) and the spacers (7) as shown on Figure 6.4 and tighten them to the body.

After tightening the protective cover (1), mounting procedure is complete. The transmitter is ready to be energized and tested. It is recommended that adjustment be done on the ZERO TRIM and on the UPPER PRESSURE TRIM.

6.8

Maintenance

Interchangeability

In order to obtain an accurate and better temperature compensated response, each sensor is submitted to a characterization process and the specific data is stored in an EEPROM located in the sensor body.

The main board, in this operation, reads the sensor serial number and compares it with the number stored in the main board. In case they do not match, the circuit considers that the sensor has been changed and will probe the memory of the new sensor for the following information:

Information not transferred during sensor replacement will remain unchanged in the main board memory. Thus, information such as Upper Value, Lower Value, Damping, Pressure Unit and replaceable transmitter parts (Flange, O-ring, etc.) shall be updated, depending whether the correct information is that of the sensor or the main board. In the case of a new sensor, the main board will have the most updated information; in the opposite case, the sensor will have the correct information. Depending on the situation, the updating shall be from one or the other.

Data transference from the main board to the sensor or vice versa can also be forced by function MAINT/BACKUP/READ FROM SENSOR.

Returning Materials

Should it become necessary to return the transmitter and/or configurator to SMAR, simply contact our office, informing the defective instrument serial number, and return it to our factory.

If it becomes necessary to return the transmitter and/or configurator to Smar, simply contact our office, informing the defective instrument's serial number, and return it to our factory. In order to speed up analysis and solution of the problem, the defective item should be returned with the Service Request Form (SRF – Appendix B) properly filled with a description of the failure observed and with as much details as possible. Other information concerning to the instrument operation, such as service and process conditions, is also helpful.

Instruments returned or to be revised outside the guarantee term should be accompanied by a purchase order or a quote request.

Lifetime Transmitter

The LD400 HART® Smart Pressure Transmitter has a life span of 50 years. The reliability data listed in the FMEDA report are only valid for this period. After this time the transmitter may present failures.
