Proline t-mass 65 PROFIBUS DP/PA Safety instructions

1 Safety instructions

1.1 Designated use

The measuring device described in these Operating Instructions is to be used only for measuring the
mass flow rate of gases (e. g. kg, Nm
temperature. The measuring device can be configured to measure a standard range of pure gases or
gas mixtures.

Examples:

•Air

• Oxygen

• Nitrogen

• Carbon Dioxide

•Argon, etc.

The use with corrosive, saturated or unclean gases should be treated with caution (contact your
Endress+Hauser sales representative). 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.

scf). At the same time, the system also measures gas

1.2 Installation, commissioning and operation

Note the following points:

• Installation, connection to the electricity supply, commissioning and maintenance of the device
must be carried out by trained, qualified specialists authorised 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.

• The device must be operated by persons authorised and trained by the facility's owner-operator.
Strict compliance with the instructions in the Operating Instruction is mandatory.

• 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 user 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 system is correctly wired in accordance with the
wiring diagrams. The transmitter must be earthed 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.

Safety instructions Proline t-mass 65 PROFIBUS DP/PA

1.3 Operational safety

Note the following points:

• Measuring systems 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. 0 Europe, 2 USA, 1 Canada).

• 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.

• The separate document on the Pressure Equipment Directive must be observed for devices used
in Category II or III installations in accordance with the Pressure Equipment Directive.

• The manufacturer reserves the right to modify technical data without prior notice. Your
Endress+Hauser distributor will supply you with current information and updates to these
Operating Instructions.

1.4 Return

• Do not return a measuring device if you are not absolutely certain that all traces of hazardous
substances have been removed, e.g. substances which have penetrated crevices or diffused
through plastic.

• Costs incurred for waste disposal and injury (burns, etc.) due to inadequate cleaning will be
charged to the owner-operator.

• Please note the measures on  ä 106

• Check the shipment, make sure nothing is missing and that the scope of supply matches your
order.

3.1.2 Transport

The following instructions apply to unpacking and to transporting the device to its final location:

• Transport the devices in the containers in which they are delivered.

• The covers or caps fitted to the process connections prevent mechanical damage to the
transducers during transportation and storage. Consequently, 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 ( å 4). 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.
At all times, therefore, make sure that the device does not unexpectedly turn around its axis or slip.

a0004294

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

3.1.3 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 °F 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.

3.2 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 and the medium temperature range ( ä 111)
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.

3.2.1 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 is provided in the
"Documentation" section on  ä 116.

3.2.2 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.

3.2.3 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 inch) for diameters < DN 200 (8")
– 3 mm (0.12 inch) for diameters  DN 200 (8")

For further information please refer to ISO 14511.

3.2.5 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 please refer to ISO 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 and a bend are mounted upstream of
the flowmeter, the recommended inlet length should be according to the control valve (50 × DN).

• For very light gases such as Helium and Hydrogen all upstream distances should be doubled.

The minimum recommendations for inlet and outlet runs (without flow conditioner) are:

This is a special Endress+Hauser version designed specially 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 two pipe flange and the flow meter
flange  å 7 .
Use only bolts which match to tehflange bolt hole and this will ensure that the correct positioning
of the plate can be found. 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.

Note!

• For optimum performance, it is advised that the t-mass F sensor and flow conditioner are ordered
at the same time such that they are calibrated together. To retrospectively fit a flow conditioner
will have a small effect on the measurement performance.

• The use of other types of flow conditioners, other than the Endress+Hauser flow conditioner, with
the t-mass F sensor will have an impact on the measurement performance due to the effects of
flow profile and pressure drop.

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

4.1 Cable specifications

4.1.1 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.

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 AWG 22

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 1500 3000 to 12 000

Line length [m]([inch]) 1200 (4000) 1 000 (3 300) 400 (1300) 200 (650) 100 (330)

• 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

Endress+Hauser 27

Wiring Proline t-mass 65 PROFIBUS DP/PA

Spurs

Please note the following:

• 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 communication
 ä 45.

Further information

General information and further notes regarding the wiring can be found in BA034S/04:
"Guidelines for planning and commissioning, PROFIBUS DP/PA, field communication".

4.1.2 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 connection technology of PROFIBUS PA 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

4.4 Degree of protection

The 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  ä 109)

• 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.

Proline t-mass 65 PROFIBUS DP/PA Operation

5.3.1 General notes

The Quick Setup menu ( ä 48) contains the default settings that are adequate for commissioning.
Complex measuring operations on the other hand necessitate additional functions that you can
configure as necessary and customise 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.  ä 38

• 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.

!

"

"

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 parameterised values remain safely stored in the EEPROM.

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.

5.3.2 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 = 65) 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 entered as the customer's code, programming is always enabled.

• Your Endress+Hauser representative can be of assistance if you mislay your personal 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 representative. Please contact
Endress+Hauser if you have any questions.

5.3.3 Disabling the programming mode

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

5.4 Error messages

5.4.1 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 system distinguishes between two types of error:

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

etc.  ä 90

• Process error: This group includes all application errors, e.g. flow limit, etc.  ä 97

a0000991

Fig. 29: Error messages on the display (example)

1 Error type: P = process error, S = system error
2 Error message type: $ = fault message, ! = notice message, definition
3 Error designation: e.g. FLOW LIMIT = maximum flow limit exceeded
4 Error number: e.g. #422
5 Duration of most recent error occurrence (in hours, minutes and seconds)

5.4.2 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.  ä 89
Serious system errors, e.g. module defects, are always identified and classed as "fault messages" by
the measuring device.

5.6 PROFIBUS DP hardware settings

5.6.1 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. Make sure that the power
supply is switched off before you remove the cover of the electronics compartment.

1. Switch off power supply.

2. Remove the I/O board.

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

5.6.2 Configuring the device address

The address must always be configured for a PROFIBUS DP measuring device. The valid device
addresses are in the range from 1 to 126. In a PROFIBUS DP network, each address can only be
assigned once. 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. Make sure that the power
supply is switched off 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) by loosening 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.

5.6.3 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.
Make sure that the power supply is switched off 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.

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.

– 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.

5. Configuration of the Analog Input function blocks 1 to 3:
The measuring device has three Analog Input function block (AI modules), through which the
various measured variables can be cyclically transmitted to the PROFIBUS Master (class 1).
The assignment of a measured variable to the Analog Input function block is shown below
using the example of Analog Input function block 1 (AI module, slot 1).

Using the CHANNEL function, you can determine the measured variable (e.g. mass flow) to
be cyclically transmitted to the PROFIBUS Master (class 1):

a. Select COMMUNICATION  BLOCK SELECTION

b. Select the option AI1 - OUT VALUE

c. Select the function CHANNEL

d. Select the option MASS FLOW

Possible setting

Measured variable ID for CHANNEL function

MASS FLOW (factory setting AI function block 1) 277

CORR. VOLUME FLOW (factory setting AI function block 2) 398

TEMPERATURE (factory setting AI function block 3) 285

Note!

!

If, when the PROFIBUS network configuration, the module "AI" was integrated in slot 1, 2 or 3, the measured
variable selected in the CHANNEL function is transmitted cyclically to the PROFIBUS Master (class 1) for the
respective Analog Input function block 1 to 3 (PROFIBUS DP ä 66, PROFIBUS PA  ä 75).

6. Configuration of totalizers 1 to 2:
The measuring device has two totalizers. The following example describes the configuration of
the totalizer using totalizer 1 as an example.
Using the CHANNEL function, you can determine the measured variable (e.g. totalized mass
flow) to be cyclically transmitted to the PROFIBUS Master (class 1) as a totalizer value:

a. Select TOTALIZER  SELECT TOTALIZER

b. Select the option TOTALIZER 1

c. Go to the function CHANNEL

d. Select the option MASS FLOW

Possible setting

Totalizer value / measured variable ID for CHANNEL function

MASS FLOW (factory setting totalizer 1 to 2) 277

CORR. VOLUME FLOW 398

If, when the PROFIBUS network configuration, the module or the function "TOTAL" was integrated in slot 4 or 5,
the measured variable selected in the CHANNEL function is transmitted cyclically to the PROFIBUS Master
(class 1) for the respective totalizer 1 to 2 (PROFIBUS DP  ä 66, PROFIBUS PA  ä 75).

• Enter the desired unit for the totalizer: TOTALIZER  UNIT TOTALIZER

• Configure totalizer status (e.g. totalize): TOTALIZER  SET TOTALIZER  Option: TOTALIZE

• Set the totalizer mode: TOTALIZER  MODE TOTALIZER: Select one of the following options:

– BALANCE (factory setting): calculates the positive and negative flow portions.
– POSITIVE: calculates the positive flow portions.
– NEGATIVE: calculates the positive flow portions.
– HOLD VALUE: The totalizer remains at the last value.

6.5 PROFIBUS DP/PA system integration

6.5.1 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 place, a decision should be made as to which GSD file should 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.

t-mass 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, device­specific 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  ä 64

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. Note the specifications of the PROFIBUS Master.

6.5.2 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
S7-300/400:
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 configuration software other than that referred to above, 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
 ä 65

6.5.3 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!

6.6.2 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:

Commissioning Proline t-mass 65 PROFIBUS DP/PA

6.8 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 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

6.8.1 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.  ä 41. 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.

6.8.2 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.

6.9 Adjustment

6.9.1 Zero point adjustment

Calibration takes place under reference operating conditions. ( ä 109).
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.

However, with some gases and /or a combination of high static line pressures, the zero point may
need to be adjusted under process conditions to restore the very low measurement capability of the
device.

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 shut-off valves upstream and/or downstream of the sensor.
– 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

a0003601

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

Endress+Hauser 83

Note!
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/…).

Commissioning Proline t-mass 65 PROFIBUS DP/PA

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, select the ZEROPOINT ADJUSTMENT function in the function matrix:
PROCESS PARAMETER  ZERO POINT ADJUST

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 flo w in the p ipe is un stable, 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.

6.10 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.

6.10.1 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.

6.10.2 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). Detailed instructions  ä 58.

Proline t-mass 65 PROFIBUS DP/PA Maintenance

7 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
production centre for service ( ä 106) or that work can only be carried out by a qualified
Endress+Hauser service person. Consult your Endress+Hauser service representative for more
information.

7.1 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.

7.2 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-stabilise.

!

"

"

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.

7.3 Transducer 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 sensor:
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
production centre.

•t-mass I sensor:
When removing the measuring sensor, observe the safety guidelines in chapter "Installation"
 ä 19.

Endress+Hauser 85

Maintenance Proline t-mass 65 PROFIBUS DP/PA

7.4 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.

Sensor-specific information:

•t-mass F sensor:
The sensor contains o-rings seals and a bushing. In case of failure, the device must be returned to
an Endress+Hauser production centre for inspection and repair.  ä 106

•t-mass I sensor:
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

7.5 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.
Please discuss your specific requirements with your Endress+Hauser service representative.

7.6 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.

Display in the PROFIBUS master system (cyclic data transmission)

If the AI or TOTAL modules are configured for cyclic data transmission, the device status is coded
in accordance with PROFIBUS Profile Specification 3.0 and transmitted with the variable to the
PROFIBUS master by means of the quality byte (byte 5). The quality byte is split into the "quality
status", "quality substatus" and "limits" segments.

a0002707-en

Fig. 45: Structure of the quality byte

The content of the quality byte depends on the failsafe mode error behavior configured in the
corresponding Analog Input function block 1 to 3 or totalizer function block 1 to 2.
Depending on which failsafe mode has been set in the FAILSAFE_TYPE function, the following
status information is transmitted to the PROFIBUS master via the quality byte:

• For the selection FAILSAFE_TYPE  FSAFE VALUE :

• For the selection FAILSAFE_TYPE  LAST GOOD VALUE (factory setting):

If a valid output value was available before the failure:

If no valid output value was available before the failure:

• For FAILSAFE_TYPE  WRONG VALUE:

Note!
The FAILSAFE_TYPE function can be configured in the corresponding Analog Input function block
1 to 3 or Totalizer function block 1 to 2 by means of an operating program (e.g. FieldCare).

You may have to change or correct certain settings of the function matrix in order to rectify faults. The functions outlined below, such as DISPLAY DAMPING, for
example, are described in detail in the "Description of Device Functions" manual.

Displayed measured value fluctuates even
though flow is steady.

Device displays flow with no actual flow
present.

1. Increase value of the TIME CONSTANT setting CURRENT OUTPUT function group.

2. Increase value of the DISPLAY DAMPING setting USER INTERFACE function group.

3. The inlet and outlet lengths must be observed. See installation conditions  ä 15

4. Consider the use of a flow conditioner. See installation conditions  ä 16

5. Relocate the meter to a point where there is less flow disturbance

1. The low flow cut off value is programmed too low. Increase value of the ON VALUE LOW FLOW CUT OFF
setting  PROCESS PARAMETERS function group (Factory setting = 1% of 20mA value).

2. Check for leaks in the pipe line downsteam of the sensor.

3. Reduce or eliminate pressure pulsations in the line.

Symptoms Rectification

Device displays flow with no actual flow
present - but with high static line pressure
and thermally conductive gases present
(e.g. Hydrogen, Helium, etc.). Line
pressure is typically > 5 bar / 75 psi

Device displays zero flow but flow is
present.

Device displays incorrect flow value. 1. Check the basic parameters of the device (Quick Setup  ä 48). Especially:

The fault cannot be rectified or some other
fault not described above has occurred.
In these instances, please contact your
Endress+Hauser representative.

Start the ZERO POINT ADJUST function  PROCESS PARAMETERS function group.
See Zero Point Adjust function  ä 83

Note!

!

Process preconditions are required before starting this function.

1. The INSTALLATION FACTOR may have a wrong setting = 0  PROCESS PARAMETERS function group (factory
setting = 1.0).

2. The LOW FLOW CUT OFF setting may be too high. Adjust the function ON VALUE LOW FLOW CUT OFF to a
lower value  PROCESS PARAMTERS function group (factory setting 1% of calibrated 20mA value).

3. The ZERO POINT ADJUST function may have been incorrectly carried out with flow present. RESET the zero
point adjustment if necessary  PROCESS PARAMETERS function group.

–Gas
– Process pressure
– Reference presssure and reference temperature
– Flow units
– Output assignment

2. Check the installation conditions (Post-installation check  ä 26)

1. The inlet and outlet lengths must be observed  ä 15.

2. Consider the use of a flow conditioner if the necessary inlet requirements cannot be met  ä 16.

3. t-mass F: Check for diameter mismatch between the flanges and check the gasket alignment ä 13.

t-mass I: Check the sensor orientation and insertion depth.  ä 19.

4. If the above actions do not resolve the problem, consider adjusting the INSTALLATION FACTOR so that the

displayed flow rate matches the expected flow rate  PROCESS PARAMETERS function group (factory
setting 1.0).

3. The flow rate maybe too high (i.e. above sensor calibration range)

1. Check the sensor measuring range using the Endress+Hauser Applicator program.

2. Check if the inverted plus sign "+" is shown on the display? If yes, reduce the velocity if possible.

4. The flow rate maybe too low

1. Check the sensor measuring range using the E+H Applicator program.

2. Increase the velocity if possible.

5. Check the condition of the transducer

1. Are the measuring elements bent? If yes, replacement is necessary.

2. Are build-ups present? If yes, clean the sensors (Transducer cleaning  ä 85).

3. Has corrosion occured? If yes, replacement is necessary.

6. Check if the gas is wet? Is condensate present on the sensors?
If yes:

1. For horizontal pipes: Mount the sensor at 135°  ä 14

2. Install a condensate trap or filter upstream of the flowmeter

7. Check if heating devices are used upstream of the flowmeter causing possible temperature profile effects ?
If yes:

1. Relocate the flowmeter further downstream or

2. Install a flow conditioner upstream of the flowmeter

The following options are available for tackling problems of this nature:
