4.3.4Installation instructions for devices with diaphragm seals
(FMD78)
• Please note that the hydrostatic pressure of the liquid columns in the capillaries can cause
zero point shift. The zero point shift can be corrected.
• Do not clean or touch the process isolating diaphragm of the diaphragm seal with hard or
pointed objects.
• Do not remove process isolating diaphragm protection until shortly before installation.
Improper handling!
Damage to the device!
‣ A diaphragm seal and the pressure transmitter together form a closed, oil-filled
calibrated system. The fill fluid hole is sealed and may not be opened.
‣ When using a mounting bracket, sufficient strain relief must be ensured for the
capillaries in order to prevent the capillary bending down (bending radius 100
(3.94 in)).
‣ Please observe the application limits of the diaphragm seal filling oil as detailed in the
Technical Information for Deltabar S TI00382P, "Planning instructions for diaphragm
seal systems" section.
In order to obtain more precise measurement results and to avoid a defect in the device,
mount the capillaries as follows:
‣ Vibration-free (in order to avoid additional pressure fluctuations)
‣ Not in the vicinity of heating or cooling lines
‣ Insulate if the ambient temperature is below or above the reference temperature
‣ With a bending radius of 100 mm (3.94 in).
‣ Do not use the capillaries as a carrying aid for the diaphragm seals!
‣ The ambient temperature and length of both capillaries should be the same when using
two-sided diaphragm seal systems.
‣ Two diaphragm seals which are the same (e.g. with regard to diameter, material, etc.)
should always be used for the negative and positive side (standard delivery).

Vacuum application (FMD78)
For applications under vacuum, Endress+Hauser recommends mounting the pressure
transmitter below the diaphragm seal. This prevents vacuum loading of the diaphragm seal
caused by the presence of fill fluid in the capillary.
When the pressure transmitter is mounted above the diaphragm seal, the maximum height
difference H1 in accordance with the illustrations below must not be exceeded.
Fig. 20: Installation above the lower diaphragm seal
The maximum height difference depends on the density of the filling oil and the smallest
ever pressure that is permitted to occur at the diaphragm seal (empty vessel), see illustration
below:

As of hardware version 1.10, you will find a label in the device on the electronic insert.
6.3.3Operation
You can obtain special configuration and operating programs from various manufacturers
for the configuration, such as the FieldCare operating program from Endress+Hauser
ä 57, Section 6.6 "FieldCare". These configuration programs make it possible to configure
FF functions and all the device-specific parameters. The predefined function blocks allow
uniform access to all the network and device data.
6.3.4Network configuration
You require the following to configure a device and integrate it into an FF network:
• An FF configuration program
• The Cff file (Common File Format: *.cff, *.fhx)
• The device description (Device Description: *.sym, *.ffo, *.sy5, *.ff5)
Pre-defined standard DDs, which can be obtained from FOUNDATION Fieldbus, are available
for the basic functions of measuring devices. You require the device-specific DD to be able to
access all the functions.
The files for Deltabar S can be acquired as follows:
• Internet Endress+Hauser: http://www.de.endresss.com Search for FOUNDATION
Fieldbus
• Internet FOUNDATION Fieldbus: http://www.fieldbus.org
• On CD-ROM from Endress+Hauser, order number: 56003896
The device is integrated into the FF network as follows:
• Start the FF configuration program.
• Download the Cff and device description files (ffo, *.sym, *.cff or *.fhx files) to the system.
• Configure the interface, see Note.
• Configure the device for the measuring task and for the FF system.
• For more in-depth information on integrating the device into the FF system, see the
description for the configuration software used.
• When integrating the field devices into the FF system, make sure you are using the right
files. You can read out the required version by means of the DEV_REV and DD_REV
parameters in the Resource Block.

6.3.6Deltabar S block model
With FOUNDATION Fieldbus, all the device parameters are categorized according to their
functional properties and task and are generally assigned to three different blocks.
A FOUNDATION Fieldbus device has the following block types:
• A Resource Block (device block):
This block contains all the device-specific features of the device.
• One or more Transducer Blocks
A Transducer Block contains all the measuring and device-specific parameters of the
device. The measuring principles, such as pressure or totalizers, are mapped in the
40Endress+Hauser
Transducer Blocks.
• One or more function blocks:
Function blocks contain the automation functions of the device. A distinction is made
between different function blocks such as the Analog Input Block or Proportional Integral
Differential Block (PID). Each of these function blocks is used to execute different
application functions.
The function blocks can be connected by means of an FF configuration program, depending
on the automation task. The device thus takes on simple control functions, thereby relieving
the workload on the higher-order process control system.
Deltabar S has the following blocks:
• Resource Block (device block)
Page 41
Deltabar S FMD77, FMD78, PMD75 with FOUNDATION FieldbusOperation
This Block supplies the output variables PRIMARY_VALUE and SECONDARY_VALUE. It
contains all the parameters to configure the measuring device for the measuring task
such as measuring mode selection, linearization function and unit selection.
– Service Transducer Block
This Block supplies the output variables COUNTER P_PMAX, PRESSURE_1_ MAX_
RESETABLE and PRESSURE_1_AFTER_DAMPING. It also includes all the counters for
measuring range overshoot/undershoot for pressure and temperature, minimum and
maximum measured values for pressure and temperature and the HistoROM function.
– DP Flow Block
This Block supplies the output variable TOTALIZER_1_VALUE/TOTALIZER 1. It
contains all the parameters that are needed to configure this totalizer.
– Display Transducer Block
This Block does not return any output variables. It contains all the parameters for
configuring the onsite display such as DISPLAY_CONTRAST.
– Diagnostic Transducer Block
This Block does not return any output variables. It contains
– the simulation function for the Pressure Transducer Block
– parameters to configure the alarm response
– parameters to set the user limits for pressure and temperature.
In addition to the pre-instantiated blocks already mentioned, the following blocks can also
be instantiated:
• 3 Analog Input Blocks (AI)
• 1 Discrete Output Block (DO)
•1 PID Block (PID)
• 1 Arithmetic Block (ARB)
• 1 Signal Characterizer Block (SCB)
• 1 Input Selector Block (ISB)
• 1 Analog Alarm Block (AALB)
• Integrator Block (IT)
A total of 20 blocks can be instantiated in Deltabar S altogether, including the blocks already
instantiated. For instantiating blocks, see the appropriate Operating Instructions of the

Block configuration when device is delivered
The block model shown below illustrates the block configuration when the device is
delivered.
Fig. 32: Block configuration when device is delivered
The Pressure Transducer Block supplies the Primary Value and the sensor temperature
(secondary value). In the DP Flow Transducer Block, the flow is totalized in the "Flow"
measuring mode and output by means of the TOTALIZER_1_VALUE/TOTALIZER 1
parameter. The Primary Value, Secondary Value and TOTALIZER_1_VALUE are each
transferred to one Analog Input Block by means of the CHANNEL parameter (see also the
following section).
The Discrete Output, PID, Arithmetic, Signal Characterizer, Input Selector and Analog Alarm
Block are not connected in the as-delivered state.
Note Dependencies when setting parameters!
‣ Please note that the links between the blocks are deleted and the FF parameters are reset

CommissioningDeltabar S FMD77, FMD78, PMD75 with FOUNDATION Fieldbus
WARNING
!
NOTICE
7Commissioning
The device is configured for the Pressure measuring mode as standard. The measuring range
and the unit in which the measured value is transmitted correspond to the specifications on
the nameplate.
Exceeding the maximum allowable working pressure!
Risk of injury due to bursting of parts! Warning messages are generated if pressure is too
high.
‣ If a pressure greater than the maximum permitted pressure is present at the device, the
messages "E115 Sensor overpressure" and "E727 Sensor pressure error - overrange" are
output in succession! Use the device only within the sensor range limits
Shortfall of the allowable working pressure!
Output of messages if pressure is too low.
‣ If a pressure smaller than the minimum permitted pressure is present at the device, the
messages "E120 Sensor low pressure" and "E727 Sensor pressure error - overrange" are
output in succession! Use the device only within the sensor range limits
7.1Configuring messages
• The messages E727, E115 and E120 are "Error"-type messages and can be configured as a
"Warning" or an "Alarm". The factory setting for these messages is "Warning". This setting
prevents the BAD status from being transmitted in applications (e.g. cascade
measurement) where the user is aware of the risk of the sensor range being overshot.
• We recommend setting messages E727, E115 and E120 to "Alarm" in the following
instances:
– It is not necessary to violate the sensor range for the measuring application.
– A position adjustment must be carried out that has to correct a large measured error as
a result of the orientation of the device.
7.2Function check
Carry out a post-installation and a post-connection check as per the checklist before
commissioning the device.

7.6.2Information on flow measurement
In the "Flow" measuring mode, the device determines a volume or mass flow value from the
differential pressure measured. The differential pressure is generated by means of primary
devices such as Pitot tubes or orifice plates and depends on the volume flow or mass flow.
Four flow measuring modes are available: volume flow, norm volume flow (European norm
conditions), standard volume flow (American standard conditions) and mass flow.
In addition, the Deltabar S software is equipped with two totalizers as standard. The
totalizers add up the volume or the mass flow. The counting function and the unit can be set
separately for both totalizers. The first totalizer (totalizer 1) can be reset to zero at any time
while the second (totalizer 2) totalizes the flow from commissioning onwards and cannot be
reset.
• By means of the FieldCare operating program, a Quick Setup menu is available for each of
the measuring modes pressure, level and flow which guides you through the most
important basic functions. With the setting in the MEASURING MODE parameter, you
specify which Quick Setup menu should be displayed. ä 64, Section 7.4 "Selecting the
language and measuring mode". No Quick Setup menus are available for the FF
configuration programs.

7.7.2Information on level measurement
• A Quick Setup menu is available for each of the measuring modes Pressure and Level
which guides you through the most important basic functions. For the "Level" Quick
Setup menu, ä 75.
• Furthermore, three level modes are available for the level measurement, namely "Level
easy pressure", "Level easy height" and "Level standard". For the "Level standard" level mode,
you can choose between the "Linear", "Pressure linearized" and "Height linearized" level
types. The table in the "Overview of level measurement" section that follows provides you
with an overview of the various measuring tasks.
– With regard to the "Level easy pressure" and "Level easy height" level modes, the values
entered are not tested as extensively as in the "Level standard" level mode. In the "Level
easy pressure" and "Level easy height" level modes, the values entered for EMPTY
CALIBRATION/FULL CALIBRATION, EMPTY PRESSURE/FULL PRESSURE and EMPTY
HEIGHT/FULL HEIGHT have to be at least 1% apart. The value will be rejected with a
warning message if the values are too close together . Further limit values are not
checked; i.e. the values entered must be appropriate for the sensor and the measuring
task so that the measuring device can measure correctly.
– The "Level easy pressure" and "Level easy height" level modes comprise fewer parameters
than the "Level standard" mode and are not used to quickly and easily configure a level
application.
– Customer-specific units of level, volume and mass, or a linearization table, can only be
entered in the "Level standard" level mode.
• For a detailed description of the parameters and configuration examples, see Operating

7.10Configuring event behavior in accordance with
FOUNDATION Fieldbus Specification FF912 Field
Diagnostic Profile
The device complies with FOUNDATION Fieldbus Specification FF912. Among other things,
this means that:
• The diagnostic category according to NAMUR Recommendation NE107 is transmitted via
the fieldbus in a format that is independent of the manufacturer:
– F: Failure
– C: Function check
– S: Out of specification
–M: Maintenance required
• The user can change the diagnostic category of the event groups specified in accordance
with the requirements of the particular application.
• Certain events can be separated from their group and handled separately:
– e.g. 115: Sensor overpressure
– e.g. 715: Sensor over temperature
• Additional information and troubleshooting measures are transmitted with the event
message via the fieldbus.
7.10.1Event groups
The diagnostic events are divided into 16 groups, depending on the source and the severity
of the event. A default event category is assigned to each group at the factory. One bit of the
assignment parameters belongs to every event group.
Event severityDefault event categoryEvent source BitEvents in this group

Event severityDefault event categoryEvent source BitEvents in this group
High severityCheck (C)Sensor27• 101: C>Sensor electronic EEPROM error
The event categories are assigned to the event groups via four assignment parameters.
These parameters are located in the RESOURCE (RB2) Block:
• FD_FAIL_MAP: for event category Failure (F)
• FD_CHECK_MAP: for event category Check (C)
• FD_OFFSPEC_MAP: for event category Out of Specification (S)
• FD_MAINT_MAP: for event category Maintenance Required (M)
Each of these parameters comprises 32 bits with the following meaning:
• Bit 0: reserved by the Fieldbus Foundation. Is also set if 1 TRD is not in the AUTO mode.
• Bits 1 to 15: configurable area; certain diagnostic events can be assigned here irrespective
of the event group they are in. They are not excluded from the event group and their
behavior can be configured individually ( ä 85). In the case of Deltabar S, the following
events can be assigned to the configurable area:
– e.g. 115: Sensor overpressure
– e.g. 715: Sensor over temperature
• Bits 16 to 31: standard area; these bits are permanently assigned to the event groups. If
the bit is set to 1 this event group is assigned to the particular event category.
The factory setting of the assignment parameters is indicated in the following table. In the
factory setting, there is a clear assignment between the event severity and the event
category (e.g. the assignment parameter).

Proceed as follows to change the diagnostic behavior of an event group:
1.Open the assignment parameter to which the group is currently assigned.
2.Change the bit of the event group from 1 to 0. If using FieldCare, this is done via the
FF912 module by disabling the appropriate check box (see the following example).
3.Open the assignment parameter to which the group should be assigned.
4.Change the bit of the event group from 0 to 1. If using FieldCare, this is done via by
enabling the appropriate check box (see the following example).
Example
The Highest Severity / Electronics group contains the events 131: Checksum error in
EEPROM: min/max segment, among others. These should no longer be categorized as
Failure (F), and should be categorized as Check (C) instead.

2.In the Failure column search for the Highest Severity Electronic group and disable the
associated check box (A). Enable the appropriate check box in the Function column (B).
Please note that the "Accept" button must be pressed to confirm each entry.
It must be ensured that the appropriate bit is set in at least one of the assignment
parameters for each event group. Otherwise a category is not transmitted with the event via
the bus. The control system will therefore generally ignore the presence of the event.
The detection of diagnostic events and the transmission of the messages on the bus is
configured on the FieldCare page Expert Field Device Diagnostic Configuration. The
"Mask" column is used for the transmission of the message on the bus. It must be noted that
device messages can still be transmitted by polling the active bits in Status 1 and 2. The mask
check box acts as a negative check box, i.e. if a field is selected the associated events are not
transmitted on the bus. The Resource Block must be set to the Auto mode to transmit status
information on the bus.

7.10.3Configurable area
The event categories can be individually defined for the following events - irrespective of the
event group to which they are assigned in the factory setting:
• 115: Sensor overpressure
• 120: Sensor low pressure
• 715: Sensor over temperature
• 717: Transmitter over temperature
• 718: Transmitter under temperature
• 720: Sensor under temperature
• 726: Sensor temperature error-overrange
• 727: Sensor pressure error-overrange
• 730: LRV user limits exceeded
• 731: URV user limits exceeded
• 732: LRV-Temp. user limits exceeded
• 733: URV-Temp. user limits exceeded
• 740: Calculation Overflow, bad configuration
To change the event category, the event must first be assigned to one of the bits 1 to 15. The
FF912ConfigArea_1 to FF912ConfigArea_15 parameters in the DIAGNOSTIC
(TRDDIAG) Block are used for this purpose. The appropriate bit can then be set from 0 to 1
in the desired assignment parameter.
Example
Error 115 "Sensor overpressure" should no longer be categorized as Out of Specification
(S), and should be categorized as Function (C) instead.

3.Select one of these bits (here Configurable Area Bit 15, for instance) and select the
Sensor overpressure (B) option from the associated picklist. Confirm your choice by
pressing "Accept".
4.Enable the check box for the bit concerned (here: Configurable Area Bit 15) (C).
Confirm your choice by pressing "Accept".
Additional information:
The "Status 1" and "Status 2" tabs indicate whether an event is active.
Changing the error category for Sensor overpressure does not affect an error that already
exists. The new category is only assigned if this error occurs again after the change has been
made. The "Status 1" and "Status 2" tabs indicate whether an event is active.

7.10.4Transmission of independent event messages on the bus
Event priority
Event messages are only transmitted on the bus if their priority is between 2 and 15. Priority
1 events are displayed but are not transmitted on the bus. Events whose priority is 0 are
ignored. All events are assigned the priority 0 in the factory setting. It is possible to change
the priority individually for the four assignment parameters.
Example
The priority of the "Failure" category is to be set to "2" .
1.In the FieldCare navigation window navigate to Expert Field Device Diagnostics
Configuration
2.Select the "Standard area" tab and set the priority to "2" in the "Failure" column (D).
Suppressing certain events
It is possible to suppress certain events during transmission on the bus using a "mask" check
box. While these events are still displayed, they are not transmitted as alert objects on the
bus. This mask check box can be found in FieldCare under Expert Field Device Diagnostic Configuration. The mask check box acts as a negative check box, i.e. if a field is selected
the associated events are not transmitted on the bus.

8.1Cleaning instructions
Endress+Hauser offer flushing rings as accessories to clean process isolating diaphragms
without taking the transmitters out of the process.
For further information please contact your local Endress+Hauser Sales Center.
8.1.1Deltabar FMD77, FMD78
We recommend you perform CIP (cleaning in place (hot water)) before SIP (sterilization in
place (steam)) for pipe diaphragm seals.
A frequent use of sterilization in place (SIP) will increase the stress on the process isolating
diaphragm. Under unfavorable circumstances in the long term view we cannot exclude that
a frequent temperature change could lead to a material fatigue of the process isolating
diaphragm and possibly to a leakage.
8.2 Exterior cleaning
Please note the following points when cleaning the device:
• The cleaning agents used should not attack the surface and the seals.
• Mechanical damage to the process isolating diaphragm, e.g. due to pointed objects, must
be avoided.
• Observe degree of protection. See therefor nameplate if necessary ( ä 10).
