The use with corrosive, saturated or unclean gases should be treated with caution In such cases, please contact your Endress+Hauser sales center for clarification. The use with unstable gases or gases not deemed to be suitable by Endress+Hauser must be avoided. The measuring device is not designed to be used with liquids or fluids in the liquid phase.

Resulting from incorrect use or from use other than that designated, the operational safety of the measuring devices can be jeopardized. The manufacturer accepts no liability for damages being produced from this.

sft3). At the same time, it also measures

2.2 Installation, commissioning and operation

Note the following points:

• Installation, connection to the electricity supply, commissioning, operation and maintenance of the measuring device must be carried out by trained, qualified specialists authorized to perform such work by the facility's owner operator. The specialist must have read and understood these Operating Instructions and must follow the instructions they contain.

• Endress+Hauser is willing to assist in clarifying the chemical resistance properties of parts wetted by special fluids, including fluids used for cleaning. However small changes in temperature, concentration or the degree of contamination in the process can result in changes of the chemical resistance properties. Therefore, Endress+Hauser can not guarantee or accept liability for the chemical resistance properties of the fluid wetted materials in a specific application. The operator is responsible for the choice of fluid wetted materials in regards to their in-process resistance to corrosion.

• If carrying out welding work on the piping, the welding unit should not be grounded by means of the measuring device.

• The installer must ensure that the measuring device is correctly wired in accordance with the wiring diagrams. The transmitter must be grounded unless special protection measures have been taken e.g. galvanically isolated power supply SELV or PELV! (SELV = Safe Extra Low Voltage; PELV = Protective Extra Low Voltage)

• Invariably, local regulations governing the opening and repair of electrical devices apply.

2.3 Operational safety

Note the following points:

• Measuring devices for use in hazardous environments are accompanied by separate "Ex documentation", which is an integral part of these Operating Instructions. Strict compliance with the installation instructions and ratings as stated in this supplementary documentation is mandatory. The symbol on the front of this supplementary Ex documentation indicates the approval and the certification body (e.g. 0Europe, 2 USA, 1 Canada).

• Burn hazard! When hot fluid passes through the measuring tube, the surface temperature of the housing increases. In the case of the sensor, in particular, users should expect temperatures that can be close to the fluid temperature. If the temperature of the fluid is high, implement sufficient measures to prevent burning or scalding.

• The measuring device complies with the general safety requirements in accordance with EN 61010-1, the EMC requirements of IEC/EN 61326, and NAMUR recommendation NE 21, NE 43 and NE 53.

4.1 Incoming acceptance, transport and storage

4.1.1 Incoming acceptance

On receipt of the goods, check the following points:

• Is the packaging or content undamaged?

• Is the delivery complete and do the delivered goods match your order?

4.1.2 Transport

Observe the following instructions when unpacking and transporting the device to its final location:

• Transport the measuring device in the container in which it is delivered.

• The covers or caps fitted to the process connections prevent mechanical damage to the sealing surfaces and contamination in the measuring tube when the unit is being transported or in storage. Do not remove these covers or caps until immediately before installation.

• Do not lift measuring devices of nominal diameters > DN 40 (1½") by the transmitter housing or the connection housing in the case of the remote version →  4. For transportation purposes, use webbing slings slung round the two process connections. Do not use chains, as they could damage the housing.

Warning! Risk of injury if the measuring device slips. The center of gravity of the assembled measuring device might be higher than the points around which the slings are slung. When transporting, make sure that the measuring device does not unexpectedly turn around its axis or slip.

Fig. 4: Instructions for transporting sensors with > DN 40 (> 1½")

4.1.3 Storage

Note the following points:

• Pack the measuring device in such a way as to protect it reliably against impact for storage (and transportation). The original packaging provides optimum protection.

• The permissible storage temperature is: –40 to +80 °C (–40 to +176 °F), preferably +20 °C (+68 °F).

• Do not remove the protective covers or caps on the process connections until you are ready to install the device.

• The measuring device must be protected against direct sunlight during storage in order to avoid unacceptably high surface temperatures.

• Devices delivered with special sealing or bagging for oxygen service must remain sealed or bagged until ready for installation.

4.2 Installation conditions

Note the following points:

• The thermal dispersion principle is very sensitive to disturbed flow conditions.

• Observe the recommended inlet and outlet requirements.

• Good engineering practice is necessary for the associated pipe work and installation.

• Ensure correct alignment and orientation of the sensor.

• Take measures to reduce or avoid condensation (e.g. install a condensation trap, thermal insulation, etc.).

• The maximum permitted ambient temperatures →  116 and the medium temperature range →  116 must be observed.

• Install the transmitter in a shaded location or use a protective sun shield.

• For mechanical reasons, and in order to protect the pipe, it is advisable to support heavy sensors.

4.2.1 Dimensions

The dimensions and installation lengths of the sensor and transmitter can be found in the "Technical Information" for the device in question. This document can be downloaded as a PDF file from www.endress.com. A list of the "Technical Information" documents available can be found in the "Documentation" section on →  122.

4.2.2 System pressure and pulsating flow

Reciprocating pumps and some compressor systems can create strong changes in process pressure that can induce spurious internal flow patterns and therefore cause additional measurement error. These pressure pulses must be reduced by the appropriate measures:

• Use of expansion tanks

• Use of inlet expanders

• Relocate the flowmeter further downstream

In compressed air systems, it is recommended to mount the flowmeter after the filter, dryer and buffer devices to avoid pulsations and oil/dirt contamination. Do not mount the flowmeter directly after the compressor outlet.

4.2.3 Pipework requirements

Good engineering practice should be followed at all times:

• Correct preparation, welding and finishing techniques

• Correctly sized gaskets

• Correctly aligned flanges and gaskets

• Connecting pipe work should match the internal diameter of the flowmeter. Maximum pipe diameter mismatch should not exceed: – 1 mm (0.04 in) for diameters < DN 200 (8") – 3 mm (0.12 in) for diameters  DN 200 (8")

Further information is provided in ISO Standard 14511.

Not recommended if the vibrations are too high or if the installation is unstable.

Only suitable for clean/dry gases. Do not mount the sensor from the bottom, on horizontal pipes, if build-up

or condensate are likely to be present. Mount the sensor in a position as indicated below

If the gas is very wet or saturated with water (e. g. biogas, undried compressed air), mount in inclined orien-

tation (approx. 135° ±10°).

4.2.5 Inlet and outlet runs

The thermal dispersion principle is sensitive to disturbed flow conditions. As a general rule, the thermal flowmeter should always be installed as far away as possible from any flow disturbances. For further information ISO Standard 14511.

Note!

• Where two or more flow disturbances are located upstream of the meter, the longest indicated inlet length should prevail. For example if a control valve is additionally mounted upstream from the measuring device and an elbow on the inlet side, select the recommended inlet length for control valves: 50 × DN

Flow conditioner for use with insertion sensors 65I →  90

The well known "Mitsubishi" design is recommended for this application DN 80 mm to DN 300 mm (3" to 12"). The flow conditioner must be installed at a distance of 8 × DN upstream of the sensor. A further 5 pipe diameters minimum inlet run is required upstream of the actual conditioner itself. Measured errors can occur depending on disturbances in the inlet run. Therefore it is advisable to choose inlet runs that are as long as possible.

Note! In the case of insertion devices, the inlet run selected downstream of the conditioner should be as long as possible.

Perforated plate flow conditioners (19 hole) for use with flanged sensor 65F →  90

This is a special Endress+Hauser version designed especially for use with the t-mass F sensor (sizes DN 25 to 100 / 1" to 4"). The mounting hole patterns and sizing are of a multi-variant design which means that one plate will fit different flange pressure classes e.g. Cl. 150 and Cl. 300.

The flow conditioner and gaskets are fitted between the pipe flange and the measuring device →  7. Use only standard bolts which match the flange bolt hole to guarantee that the flow conditioner is centered correctly. The alignment notch must also be pointing in the same plane as the transmitter. Incorrect installation of the flow conditioner will have a small effect on the measurement accuracy.

A0005116

Fig. 7: Flow conditioner mounting arrangement (example)

1=perforated plate flow conditioner, 2= aeal/gasket, 3= alignment notch, 4 = alignment in the same plane as the transmitter

Note

• Order the t-mass F sensor and the flow conditioner together to ensure that they are calibrated together. Joint calibration guarantees optimum performance. Ordering the flow conditioner separately and using it with the measuring device will further increase measurement uncertainty.

• The use of conditioners from other suppliers will affect the flow profile and pressure drop and will have an adverse effect on performance.

• Bolts, nuts, seals, etc. are not included in the scope of supply and must be supplied by the customer.

4.2.6 Heating

Some applications require suitable measures to avoid heat loss (condensation). Heating can be electric, e. g. with heated elements, or by means of hot water, steam pipes or insulation.

Caution!

Risk of electronics overheating! Consequently, make sure that the adapter between sensor and transmitter and the connection housing of the remote version always remain free of insulating material.

4.2.7 Thermal insulation

When the gas is very damp or saturated with water (e. g. bio gas), the piping and flowmeter body should be insulated to prevent water droplets condensing on the measuring sensor.

5.1 Cable specifications

5.1.1 PROFIBUS DP cable specifications

Cable type

Two versions of the bus line are specified in IEC 61158. Cable type A can be used for all transmission rates up to 12 Mbit/s. Refer to the table for the cable parameters:

Cable type A

Characteristic impedance 135 to 165  at a measuring frequency of 3 to 20 MHz

Cable capacitance < 30 pF/m

Core cross-section >0.34 mm

Cable type Twisted in pairs, 1 × 2, 2 × 2 or 1 × 4 wire

Loop-resistance 110  /km

Signal damping Max. 9 dB over the entire length of the cable section

Shielding Copper braided shielding or braided shielding and foil shielding



, corresponds to 22 AWG

Bus structure

Note the following points:

• The maximum line length (segment length) depends on the transmission rate.

For cable type A, the maximum line length (segment length) is as follows:

Transmission rate [kBit/s] 9.6 to 93.75 187.5 500 1,500 3,000 to

Line length [m]([inch]) 1,200 (4,000) 1,000

(3,300)

400 (1,300) 200 (650) 100

12,000

• A maximum of 32 users are permitted per segment.

• Each segment is terminated at either end with a terminating resistor.

• The bus length or the number of users can be increased by introducing a repeater.

• The first and last segment can comprise max. 31 devices.

The segments between the repeaters can comprise max. 30 stations.

• The maximum distance between two bus users can be calculated as follows:

(NO_REP + 1) × segment length

Note!

NO_REP = maximum number of repeaters that may be switched in series depending on the repeater in question.

Example

In accordance with manufacturer specifications, 9 repeaters can be switched in series when using a standard line. The maximum distance between two bus users at a transmission rate of 1.5 MBit/s can be calculated as follows: (9 + 1) × 200 m = 2000 m.

28 Endress+Hauser

Page 29

Proline t-mass 65 PROFIBUS DP/PA Electrical connection

Spurs

Note the following points:

• Length of spurs < 6.6 m (21.7 ft) (at max. 1.5 MBit/s)

• No spurs should be used for transmission rates >1.5 MBit/s. The line between the connector and the bus driver is described as a spur. Experience has shown that you should proceed with caution when configuring spurs. For this reason, you cannot presume that the sum of all spurs at 1.5 MBit/s may be 6.6 m (21.7 ft). This is affected greatly by the arrangement of the field devices. Therefore, we recommend you do not use any spurs, if possible, at transmission rates >1.5 MBit/s.

• If you cannot avoid using spurs, then they may not include any bus terminators.

Bus termination

It is important to terminate the RS485 line correctly at the start and end of the bus segment since impedance mismatch results in reflections on the line which can cause faulty data transfer →  46.

Further information

General information and further notes regarding the wiring can be found in BA00034S/04: "Guidelines for planning and commissioning, PROFIBUS DP/PA, field communication".

5.1.2 Shielding and grounding

When planning the shielding and grounding for a fieldbus system, there are three important points to consider:

• Electromagnetic compatibility (EMC)

• Explosion protection

• Safety of the personnel

To ensure the optimum electromagnetic compatibility of systems, it is important that the system components and above all the cables, which connect the components, are shielded and that no portion of the system is unshielded. Ideally, the cable shields are connected to the normally metal housings of the connected field devices. Since these are generally connected to the protective ground, the shield of the bus cable is grounded many times. Ensure that the stripped and twisted lengths of cable shield to the ground terminal are as short as possible. This approach, which provides the best electromagnetic compatibility and personnel safety, can be used without restriction in systems with good potential matching. In the case of systems without potential matching, a power supply frequency (50 Hz) equalizing current can flow between two grounding points which, in unfavorable cases, e.g. when it exceeds the permissible shield current, may destroy the cable. To suppress the low frequency equalizing currents, it is therefore recommended - in the case of systems without potential equalization - to connect the cable shield directly to the building ground (or protective ground) at one end only and to use capacitive coupling to connect all other grounding points.

Caution!

The statutory EMC requirements are only met if the cable shield is grounded at both ends!

Fieldbus connector

Note! The connector can only be used for PROFIBUS PA devices.

The conn ecti on techn olog y of P ROFI BUS P A allows measuring devices to be connected to the fieldbus via uniform mechanical connections such as T-boxes, distribution modules etc.

This connection technology using prefabricated distribution modules and plug-in connectors offers substantial advantages over conventional wiring:

• Field devices can be removed, replaced or added at any time during normal operation. Data transmission is not interrupted.

• Installation and maintenance are significantly easier.

• Existing cable infrastructures can be used and expanded instantly, e.g. when constructing new star distributors using 4-channel or 8-channel distribution modules.

The measuring device can therefore be supplied with the option of a ready-mounted fieldbus connector. Fieldbus connectors for retrofitting can be ordered from Endress+Hauser as a spare part →  90.

5.4 Degree of protection

The measuring devices fulfill all the requirements for IP 67 (NEMA 4X).

Compliance with the following points is mandatory following installation in the field or servicing, in order to ensure that IP 67 (NEMA 4X) protection is maintained:

• The housing seals must be clean and undamaged when inserted into their grooves. The seals must be dried, cleaned or replaced if necessary.

• All threaded fasteners and screw covers must be firmly tightened.

• The cables used for connection must be of the specified outside diameter (cable entry → 

113)

• Firmly tighten the cable entries (a).

• The cables must loop down before they enter the cable entries ("water trap") (b). This arrangement prevents moisture penetrating the entry. Always install the measuring device in such a way that the cable entries do not point up.

• Remove all unused cable entries and insert blanking plugs instead.

• Do not remove the grommet from the cable entry.

6.3 Brief operating instructions for the function matrix

Note!

• See the general notes →  40.

• For a detailed description of all the functions "Description of Device Functions" manual

The function matrix is a two-level construct: the function groups form one level and the groups' functions the other. The groups are the highest-level grouping of the control options for the measuring device. A number of functions is assigned to each group. You select a group in order to access the individual functions for operating and configuring the measuring device.

1. HOME position  F  Entry into the function matrix

2. Select a function group (e.g. CURRENT OUTPUT 1)

3. Select a function (e.g. TIME CONSTANT)

Change parameter / enter numerical values:

 Select or enter enable code, parameters, numerical values

 Save your entries

4. Exit the function matrix:

– Press and hold down Esc key (X) for longer than 3 seconds  HOME position – Repeatedly press Esc key (X)  Return step by step to HOME position

Operation Proline t-mass 65 PROFIBUS DP/PA

6.3.1 General notes

The Quick Setup menu (→  49) contains the default settings that are adequate for com- missioning. Complex measuring operations on the other hand necessitate additional functions that you can configure as necessary and customize to suit your process parameters. The function matrix, therefore, comprises a multiplicity of additional functions which, for the sake of clarity, are arranged in a number of function groups.

Comply with the following instructions when configuring functions:

• You select functions as described already. →  39

• You can switch off certain functions (OFF). If you do so, related functions in other function groups will no longer be displayed.

• Certain functions prompt you to confirm your data entries. Press P to select "SURE ( YES )" and press F to confirm. This saves your setting or starts a function, as applicable.

• Return to the HOME position is automatic if no key is pressed for 5 minutes.

• Programming mode is disabled automatically if you do not press a key within 60 seconds following automatic return to the HOME position.

Caution!

All functions are described in detail, as is the function matrix itself, in the "Description of Device Functions" manual, which is a separate part of these Operating Instructions.

Note!

• The transmitter continues to measure while data entry is in progress, i.e. the current measured values are output via the signal outputs in the normal way.

• If the power supply fails, all preset and parameterized values remain safely stored in the EEPROM.

6.3.2 Enabling the programming mode

The function matrix can be disabled. Disabling the function matrix rules out the possibility of inadvertent changes to device functions, numerical values or factory settings. A numerical code (factory setting = 50) has to be entered before settings can be changed. If you use a code number of your choice, you exclude the possibility of unauthorised persons accessing data ( see the "Description of Device Functions" manual).

Comply with the following instructions when entering codes:

• If programming is disabled and the P operating elements are pressed in any function, a prompt for the code automatically appears on the display.

• If “0” is specified as the customer's code, programming is always enabled.

• Your Endress+Hauser sales center can be of assistance if you mislay your private code.

Caution!

Changing certain parameters, such as all sensor characteristics, for example, influences numerous functions of the entire measuring system, particularly measuring accuracy. There is no need to change these parameters under normal circumstances and, consequently, they are protected by a special code known only to the Endress+Hauser sales center. Please contact Endress+Hauser first if you have any questions.

6.3.3 Disabling the programming mode

Programming mode is disabled if an operating element is not pressed within 60 seconds following automatic return to the HOME position. Programming can also be disabled by entering any number in the "ACCESS CODE" function (other than the customer's code).

6.4 Error messages

6.4.1 Type of error

Errors that occur during commissioning or measuring are displayed immediately. If two or more system or process errors occur, the error with the highest priority is the one shown on the display.

The measuring device distinguishes between two types of error:

• System error→  93: This group includes all device errors, e.g. communication errors, hardware errors etc.

• Process error→  100 This group includes all application errors, e.g. flow limit etc.

= fault message, ! = notice message, definition

6.4.2 Error message type

The measuring device always assigns system and process errors which occur to two types of error messages (fault or notice messages) resulting in different weightings →  92 ff. Serious system errors, e.g. module defects, are always identified and classed as "fault messages" by the measuring device.

6.6.1 Configuring the write protection

A jumper on the I/O board provides the means of switching hardware write protection on or off. When the hardware write protection is switched on, it is not possible to write to the device parameters via PROFIBUS (acyclic data transmission, e.g. via operating program "FieldCare").

Warning! Risk of electric shock. Exposed components carry dangerous voltages. Switch off the power supply before you remove the cover of the electronics compartment.

1. Switch off the power supply.

2. Remove the I/O board.

3. Configure the hardware write protection accordingly with the aid of the jumpers (see Figure).

4. Installation is the reverse of the removal procedure.

6.6.2 Configuring the device address

The address must always be configured for a PROFIBUS DP/PA device. Valid device addresses are in the range from 1 to 126. Each address can only be assigned once in a PROFIBUS DP/PA network. If an address is not configured correctly, the device is not recognized by the master. All measuring devices are delivered from the factory with the address 126 and software addressing.

Addressing via local operation or operating program

Addressing takes place in the FIELDBUS ADDRESS function see "Description of Device Functions" manual.

Addressing via miniature switches

Warning! Risk of electric shock. Exposed components carry dangerous voltages. Switch off the power supply before you remove the cover of the electronics compartment.

1. Loosen Allen screw (3 mm) of the securing clamp.

2. Unscrew cover of the electronics compartment from the transmitter housing.

3. Remove the local display (if present). To do so, loosen the set screws of the display module.

4. Set the position of the miniature switches on the I/O board using a sharp pointed object.

6.6.3 Configuring the terminating resistors

Note! It is important to terminate the RS485 line correctly at the start and end of the bus segment since impedance mismatch results in reflections on the line which can cause faulty data transfer.

Warning! Risk of electric shock. Exposed components carry dangerous voltages. Switch off the power supply before you remove the cover of the electronics compartment.

• For baudrates up to 1.5 MBaud, the termination is set via the terminating switch SW 1 for the last transmitter on the bus: ON – ON – ON – ON.

• The measuring device is operated with a baudrate >1.5 MBaud: Due to the capacitive load of the device and the line reflection generated as a result, make sure that external termination is used.

The miniature switch for termination is located on the I/O board (see Figure):

Fig. 32: Set terminating resistors (for baud rates < 1.5 MBaud)

A = Factory setting B = Setting at the last transmitter

Note! It is generally recommended to use external termination since if a device that is terminated internally is defect, this can result in the failure of the entire segment.

7.3.3 "Gas" Quick Setup menu

The device can be setup with 1 or 2 individual gas groups in memory. This means that up to 2 different gas flow streams (e.g. nitrogen and argon) can be measured in a single pipe with one flowmeter. In the case of 2 gas groups being used, a digital input can be assigned to switch between the gas groups or, alternatively, the switch can be done manually via a function in the device software. Furthermore, a programmed gas mixture can be dynamically updated, via a signal from a gas analyzer.

Programming a gas group

The measuring device allows flexible change of the gas group parameters, independent of the original factory setup and calibration.

A gas group can be programmed as: – one single gas or – one gas mixture (of up to 8 components)

A single gas can be: – selected from a list of standard gases or – setup for other suitable types of gases, such as Ozone, using manual correction factors and

the option called SPECIAL GAS. This requires application evaluation at the factory - In this case, please contact your Endress+Hauser sales center for clarification.

7.3.5 "Heat Flow" Quick Setup menu

The measuring device can calculate and output the heat of combustion of common fuel gases such as methane, natural gas, propane, butane, ethane and hydrogen. This Quick Setup menu can be used to program the method to calculate the net calorific value or gross calorific value. The measuring device can be configured to give two independent heating value outputs and totalized values. For example, the pipeline has either natural gas or propane running at separate times and the heating value is required for both gases.

A0009909-en

Calculation mode 1 and 2

• The heating value for CALCULATION MODE 1 corresponds to the settings in the function GAS GROUP 1.

• The heating value for CALCULATION MODE 2 corresponds to the settings in the function GAS GROUP 2.

Note!

• If only one gas group is used, then leave mode 2 as default settings.

• The units of measure are selected in the system units section →  50.

Auto Gross

The gross heating value (or higher heating value) is the total heat obtained by complete combustion at constant pressure of a volume of gas in air, including the heat released by the water vapor in the combustion products (gas, air and combustion products taken at reference cumbustion temperature and standard pressure).

Auto Net

The net heating value (or lower heating value) is determined by subtracting the heat of vaporization of the water vapor from the higher heating value. This treats any water formed as water vapor. The energy required to vaporize the water therefore is not realized as heat.

7.3.7 Data backup/transmission

Using the T-DAT SAVE/LOAD function, you can transfer data (device parameters and settings) between the T-DAT (exchangeable memory) and the EEPROM (device storage unit).

This is required in the following instances:

• Creating a backup: current data are transferred from an EEPROM to the T-DAT.

• Replacing a transmitter: current data are copied from an EEPROM to the T-DAT and then transferred to the EEPROM of the new transmitter.

• Duplicating data: current data are copied from an EEPROM to the T-DAT and then transferred to EEPROMs of identical measuring points.

Note! For information on installing and removing the T-DAT →  102

7.4 Commissioning the PROFIBUS interface

Note!

• All functions required for commissioning are described in detail in the "Description of Device Functions" manual which is a separate part of this Operating Manual.

• A code (factory setting: 65) must be entered to change device functions, numerical values or factory settings →  40.

7.4.1 PROFIBUS DP/PA commissioning

The following steps must be carried out in the sequence specified:

1. Check the hardware write protection:

The WRITE PROTECT parameter indicates whether it is possible to write to the device parameters via PROFIBUS (acyclic data transmission, e.g. via operating program "FieldCare").

Note!

This check is not needed if operating via the local display. COMMUNICATION  WRITE PROTECT  Display of one of the following options: – OFF (factory setting) = write access via PROFIBUS possible – ON = write access via PROFIBUS not possible Deactivate the write protection if necessary. PROFIBUS DP →  44, PROFIBUS PA →  47

2. Enter the tag name (optional):

COMMUNICATION  TAG NAME

3. Configuring the fieldbus address:

‣ Software addressing using the local display or operating program:

COMMUNICATION  FIELDBUS ADDRESS

‣ Hardware addressing via miniature switches

PROFIBUS DP →  45, PROFIBUS PA →  48

4. Select the system unit:

a. Determine the units by means of the "System units" group: SYSTEM UNITS  UNIT

MASS FLOW / UNIT CORR. VOLUME FLOW/ UNIT…

b. In the function UNIT TO BUS, select the option SET UNITS so that the measured vari-

ables transmitted cyclically to the PROFIBUS Master (class 1) are transmitted with the system units set in the measuring device: COMMUNICATION  UNIT TO BUS

Note!

– The configuration of the system units for the totalizer is described in step 6. – If the system unit of a measured variable is changed by means of the local operation

or an operating program, this initially does not have any effect on the unit that is used to transmit the measured variable to the PROFIBUS Master (class 1). Changed system units of the measured variables are not transmitted to the PROFIBUS Master (class 1) until the SET UNITS option is activated in the function COMMUNICATION  UNIT TO BUS.

7.5 PROFIBUS DP/PA system integration

7.5.1 Device master file (GSD file)

For PROFIBUS network configuration, the device master file (GSD file) is needed for every bus participant (PROFIBUS slave). The GSD file contains a description of the properties of a PROFIBUS device, such as supported data transmission rate and number of input and output data. Before configuration takes plac e, a d ecis ion sh oul d be ma de as to wh ich G SD fi le sh ould be used to operate the measuring device in the PROFIBUS DP Master (class 1) system.

The measuring device supports the following GSD files:

• t-mass GSD file (manufacturer-specific GSD file, complete device functionality)

• PROFIBUS Profile GSD file:

Below you will find a detailed description of the GSD files supported.

GSD file (manufacturer-specific GSD file, complete device functionality)

Use this GSD file to access the complete functionality of the measuring device. In this way, device-specific measured variables and functions are thus completely available in the PROFIBUS master system. An overview of the modules available (input and output data) is contained on →  65.

GSD file with standard or extended format

The GSD file with either the standard or the extended format must be used depending on the PROFIBUS Master used. When installing the GSD file, the GSD file with the extended format (EH3x15xx.gsd) should always be used first. However, if the installation or the configuration of the measuring device fails with this format, then use the standard GSD (EH3_15xx.gsd). This differentiation is the result of different implementation of the GSD formats in the master systems. Pay attention to the specifications of the configuration software.

7.5.2 Example for selecting the GSD file

Before configuration takes place, a decision should be made as to which GSD file should be used to configure the measuring device in the PROFIBUS master system. The following example describes the use of the t-mass 65 GSD file (complete functionality) for PROFIBUS PA:

Select the t-mass 65 GSD file in the measuring device by means of the SELECTION GSD function. COMMUNICATION  SELECTION GSD  Select: MANUFACT. SPEC.

1. Before configuring the network, load the t-mass 65 GSD file into the configuration system/master system.

Note!

When installing the GSD file, always first use the GSD file with the extended format (EH3x1545.gsd). However, if the installation or the configuration of the device fails with this format, then use the standard GSD (EH3_1545.gsd).

Example for the configuration software Siemens STEP 7 of the Siemens PLC family S7300/400: Use the t-mass 65 GSD file with the extended format (EH3x1545.gsd). Copy the file to the subdirectory …\ siemens \ step7 \ s7data \ gsd. The bitmap files also belong to the GSD files. These bitmap files are used to display the measuring points in image form. The bitmap files must be saved to the directory "…\ siemens \ step7 \ s7data \ nsbmp".

If you are using another configuration software, ask your PROFIBUS master system manufacturer which directory you should use.

2. t-mass 65 is a modular PROFIBUS slave, i.e. the desired module configuration (input and output data) must be performed in the next step for t-mass 65. This can be done directly by means of the configuration software. A detailed description of the modules supported by the measuring device can be found on →  66.

7.5.3 Maximum number of writes

If a non-volatile device parameter is modified via the cyclic or acyclic data transmission, this change is saved in the EEPROM of the measuring device. The number of writes to the EEPROM is technically restricted to a maximum of 1 million. Attention must be paid to this limit since, if exceeded, it results in data loss and measuring device failure. For this reason, avoid constantly writing non-volatile device parameters via the PROFIBUS!

7.6.2 Modules for cyclic data transmission

The measuring device is a so-called modular PROFIBUS slave. In contrast to a compact slave, the structure of a modular slave is variable - it consists of several individual modules. In the GSD file, the individual modules (input and output data) are described with their individual properties. The modules are permanently assigned to the slots, i.e. the sequence or arrangement of the modules must be observed when configuring the modules (see following table). Gaps between configured modules have to be assigned the EMPTY_MODULE module.

To optimize the data throughput rate of the PROFIBUS network, it is recommended to only configure modules that are processed in the PROFIBUS master system.

It is essential to adhere to the following sequence/assignment when configuring the modules in the PROFIBUS master system:

Note!

• The assignment of the measured variables for the Analog Input function blocks (1 to 3)

and the totalizer function blocks (1 to 2) can be changed by means of the CHANNEL function. A detailed description of the individual modules is contained in the following section.

• The measuring device has to be reset once a new configuration has been loaded to the

automation system. This can be effected as follows: – By means of the local display – By means of an operating program (e.g. FieldCare) – By switching the supply voltage off and on again.

Assignment of the measured variables to the TOTAL module

The TOTAL module can transmit different totalizer variables to the PROFIBUS Master (class

1).

The measured variables are assigned to the totalizer function blocks 1 to 2 by means of the local display or with the aid of an operating program (e.g. FieldCare) in the CHANNEL function:

•TOTALIZER  SELECT TOTALIZER: Selection of a totalizer

• COMMUNICATION  CHANNEL: Selection of a measured variable

SETTOT_TOTAL module

The module combination SETTOT_TOTAL (slots 4 to 5) consists of the functions SETTOT and TOTAL. With this module combination:

• The totalizer can be controlled via the PROFIBUS Master (SETTOT).

• The totalizer value, is transmitted, including the status (TOTAL).

SETTOT function

In the SETTOT function, the totalizer can be controlled via control variables. The following control variables are supported:

• 0 = Totalize (factory setting)

• 1 = Reset totalizer (the totalizer value is reset to 0)

• 2 = Accept totalizer preset

Note! After the totalizer value has been reset to 0 or set to the preset value, the totalizing continues automatically. The control variable does not have to be changed to 0 again to restart totalizing. Stopping totalizing is controlled in the SETTOT_MODETOT_TOTAL module via the MODETOT function. →  69

CONTROL_BLOCK module

By means of the CONTROL_BLOCK module (slot 11), the measuring device is able to process device-specific control variables from the PROFIBUS Master (class 1) in cyclic data transmission (e.g. switching on positive zero return).

Supported control variables of the CONTROL_BLOCK module

The following device-specific control variables can be activated by changing the output byte from 0  x:

Module Control variables

0  2: Positive zero return ON

CONTROL_BLOCK

0  3: Positive zero return OFF 0  4: Carrying out the zero point adjustment 0  24: Run UNIT TO BUS function

Note! The control (e.g. switching on positive zero return) is executed by cyclic data transmission if the output byte switches from "0" to the bit pattern in question. The output byte must always switch from "0". A switchback to "0" does not have any effect.

Example (change the output byte)

From  To Result

0  2 Positive zero return is switched on.

7.8 PROFIBUS DP/PA acyclic data transmission

Acyclic data transmission is used to transmit parameters during commissioning or maintenance, or to display additional measured variables that are not included in data transmission. Thus parameters for identification, control or adjustment in the various blocks (physical block, transducer block, function block) can be changed while the measuring device is in the process of data transmission with a PLC.

The measuring device supports the two basic types of acyclic data transmission:

• MS2AC communication with 2 available SAP´s

• MS1AC communication

7.8.1 Master class 2 acyclic (MS2AC)

MS2AC is acyclic data transmission between a field device and a master (class 2), e.g. FieldCare, Siemens PDM etc. →  42. During this process, the master opens a communication channel via an SAP (Service Access Point) to access the device. All parameters to be exchanged with a device via PROFIBUS must be made known to a Class 2 master. This assignment to each individual parameter takes place either in a device description (DD), a DTM (Device Type Manager), or inside a software component in the master via slot and index addressing.

When using MS2AC communication, note the following:

• As described above, a Master (class 2) accesses a device via special SAP´s. Therefore, the number of Master (class 2) that can communicate with a device simultaneously is limited to the number of SAPs available for this data transmission.

• The use of a Master (class 2) increases the cycle time of the bus system. This must be taken into account when programming the control system used.

7.8.2 Master class 1 acyclic (MS1AC)

In MS1AC, a cyclic master, that is already reading the cyclic data from the device or writing to the device opens the communication channel via the SAP 0x33 (special Service Access Point for MS1AC) and can then read or write a parameter acyclically like a Class 2 master via the slot and the index (if supported). When using MS1AC communication, note the following:

• Currently, few PROFIBUS masters on the market support this data transmission.

• MS1AC is not supported by all PROFIBUS devices.

• In the user program, note that constant writing of parameters (for example, at every cycle of the program) can drastically reduce the service life of a device. Acyclically written parameters are written to voltage-resistant memory modules (EEPROM, Flash etc.). These memory modules are designed for a limited number of write operations. In normal operation without MS1AC (during parameter configuration), the number of write operations does not even come close to this number. If programming is incorrect, this maximum number can be reached quickly, drastically reducing a device's service life.

Note!

The memory module of the measuring device is designed for one million write operations.

7.9 Adjustment

7.9.1 Zero point adjustment

Calibration takes place under reference operating conditions. (→  113). Consequently, the zero point adjustment is generally not necessary! At zero flow conditions, the output of most thermal mass flow devices has a strong dependency on the process pressure. The effect on the true zero point of the device, by the static line pressure, is dependant on the gas type and the application demands and in many cases the use of the low flow cut-off function is adequate to zero the device output.

With some gases and/or a combination of high pressures, zero point adjustment must be performed under process conditions so that the measuring device can measure smaller values.

Therefore, the zero point adjustment is advisable in the following special cases:

• To achieve highest measuring accuracy with very small flow rates.

• Under process or operating conditions where the gas properties (heat capacity and thermal conductivity) will change e.g. Hydrogen and Helium.

Preconditions for a zero point adjustment

Note the following before you perform a zero point adjustment:

• A zero point adjustment can be performed only with gases that contain no solid contents or condensate.

• The adjustment is performed with the process gas at zero flow and at operating pressure. This can be achieved, for example, with shutoff valves upstream and/or downstream of the sensor or by using existing valves and gates. –Normal operation  valves 1 and 2 open –Zero point adjustment with pump pressure  Valve 1 open / valve 2 closed –Zero point adjustment without pump pressure  Valve 1 closed / valve 2 open

Fig. 44: Zero point adjustment and shut-off valves

Caution!

You can view the currently valid zero point value using the ZERO POINT function in the SENSOR DATA group (see the "Description of Device Functions" manual, BA000114D/06/…).

84 Endress+Hauser

A0003601

Page 85

Proline t-mass 65 PROFIBUS DP/PA Commissioning

Performing a zero point adjustment

1. Operate the system until operating conditions have settled.

2. Stop the flow (v = 0 m/s).

3. Check the shut-off valves for leaks.

4. Check that operating pressure is correct.

5. Using the local display/operating program, select the ZEROPOINT ADJUSTMENT function in the function matrix: PROCESS PARAMETER  ZEROPOINT ADJUSTMENT

6. When you press O or S you are automatically prompted to enter the access code if the function matrix is still disabled. Enter the code (factory setting = 65).

7. Use O or S to select START and press F to confirm. The zero point adjustment now starts and is completed within a few seconds.

Note!

If the flow in the pipe is unstable, the following error message may appear on the display "ZERO ADJUST FAIL". The zero point adjustment has failed. The preconditions need to be stabilised before attempting a new adjustment.

8. Back to the HOME position: – Press and hold down Esc key (X) for longer than three seconds or – Repeatedly press and release the Esc key (X).

Resetting a zero point adjustment

The currently stored zero point can be reset to the original factory value by using the RESET option within ZERO POINT ADJUST. Use O or S to select RESET and press F to confirm. The zero point adjustment is now reset.

7.10 Data storage device (HistoROM)

At Endress+Hauser, the term HistoROM refers to various types of data storage modules on which process and measuring device data are stored. By plugging and unplugging such modules, device configurations can be duplicated onto other measuring devices to cite just one example.

7.10.1 HistoROM/S-DAT (sensor-DAT)

The HistoROM/S-DAT is an exchangeable data storage device in which all sensor relevant parameters are stored, i.e., pipe type, diameter, serial number, flow conditoner, zero point.

7.10.2 HistoROM/T-DAT (transmitter-DAT)

The HistoROM/T-DAT is an exchangeable data storage device in which all transmitter parameters and settings are stored. Storing of specific parameter settings from the EEPROM to the HistoROM/T-DAT and vice versa has to be carried out by the user (= manual save function). For detailed information →  59.

7.10.3 Gas compensation input

The flowmeter can read the composition of the gas from the gas analyzer and automatically update the first two gas components (e.g. GAS TYPE 1 and 2) in the programmed gas mixture. This provides a more accurate measurement in case of varying compositions. For example: varying methane and carbon dioxide components in a biogas application.

53).

• Check the actual % value of the main gas component being transmitted from the analyzer:

Go to the function MOLE % GAS 1 in the function group PROCESS PARAMETER.

• A gas group must contain at least 2 gas types (e.g. methane 60%, carbon dioxide 40%).

• By default, the first gas fraction is then updated continuously by the gas chromatograph

and the content of the other gases is calculated dynamically

Maintenance Proline t-mass 65 PROFIBUS DP/PA

8 Maintenance

Generally, the flowmeter requires no special maintenance work, particularly if the gas is clean and dry.

Warning! Hazardous area approvals may demand that the device be returned to an Endress+Hauser sales center (→  109) for service or that work can only be carried out by a qualified Endress+Hauser service person. Please contact your Endress+Hauser sales center if you have any questions.

8.1 External cleaning

When cleaning the exterior of measuring devices, always use cleaning agents that do not attack the surface of the housing and the seals.

8.2 Pipe cleaning

The sensor is capable of withstanding clean in place (CIP) processes using heated liquids or steam (SIP), within the maximum specified temperature limits. However the sensor measurement will be adversely affected during the cleaning cycle and a settling down period will be required after the cycle to allow the process and sensor temperatures to re-stabilize.

Note! The POSITIVE ZERO RETURN function maybe activated to set the current output to zero flow during such cycles. See "Description of Device Functions" manual for more information.

Caution! Do not use a pipe cleaning pig.

8.3 Sensor cleaning

For gases that do carry impurities, it is recommended that the sensor be routinely inspected and cleaned to minimise any potential measuring errors due to contamination or build-ups. The frequency of inspection and cleaning will depend upon the application and expected measurement performance. Cleaning is performed by applying a non-filming or oil-free type cleaning fluid to a soft brush or cloth and gently wiping over the surface until all build-ups and contaminants are removed.

Caution!

• Use care not to bend the sensing elements of the transducer during cleaning.

• Do not use abrasive materials or fluids corrosive to the sensor materials and seals.

Sensor-specific information:

• t-mass F:

Removal of the transducer requires specialist knowledge, tools and parts. The process seal also may need to be tested and re-qualified. This procedure must be carried out by an Endress+Hauser sales center.

• t-mass I:

When removing the measuring sensor, observe the safety guidelines in chapter "Installation" →  19.

88 Endress+Hauser

Page 89

Proline t-mass 65 PROFIBUS DP/PA Maintenance

8.4 Replacing seals

Under normal circumstances, fluid wetted seals of the sensor do not require replacement. Replacement is necessary only in special circumstances, for example if aggressive or corrosive fluids are incompatible with the seal material. Only Endress+Hauser seals may be used.

Sensor-specific information:

• t-mass F: The sensor contains o-rings seals and a bushing. In case of failure, the device must be returned to an Endress+Hauser sales center for inspection and repair (→  109).

• t-mass I: The transducer is welded to the insertion tube and has no exchangeable seals. The compression fitting contains wetted seals (ferrules) and a bonded seal is used on the G 1 A thread version.

Caution!

Do not reuse gaskets after removing sensors. Use only original parts from Endress+Hauser. The compression fitting and gasket seals are deliverable as spare parts. The seal ring can be replaced easily on site

8.5 In-situ calibration

The t-mass flowmeters are designed to support in-situ calibration using a reference meter signal, thus saving time and cost by reducing the need for factory re-calibration. Pre-requirements for in-situ calibration with adjustment:

1. Stable gas composition (operation with one gas group only; without gas analyzer input)

2. Stable pressure and temperature (without pressure compensation input)

3. Mass flow reference

a. mass flow reference meter, mounted in the measurement or bypass pipe, providing

a mA signal to t-mass or

b. manual entry of known mass flow reference values. For example, the display value

from the reference meter or a derived value from a pump curve)

4. Ability to control the flow range over a minimum of 5 control points

This function is activated using the service access code. For specific applications, contact your Endress+Hauser sales center.

8.6 Recalibration

For thermal meters, the interval between calibrations is dependent on the application since calibration drift is predominantly caused by contamination of the sensor surface. If the gas is not clean (i.e. contains particulates), then gentle cleaning of the sensor elements can be effective at regular intervals. The cleaning interval will depend upon the nature and extent of the contamination.

Determination of recalibration intervals:

• If the measurement is critical, then a calibration audit should be undertaken by performing recalibration checks once per year for a period of 2 years. Increase that period to twice per year if the application gas is not clean and dry. Depending on the results of the audit, the next recalibration check interval can be increased or decreased accordingly.

• For non-critical applications and or where the gas is clean and dry, a recalibration interval of every 2 to 3 years is recommended.
