Note!

• Due to the orientation of the Deltabar M, there may be a shift in the measured value, i.e. when
the container is empty, the measured value does not display zero. You may correct this zero
point shift by a position adjustment in one of the following ways:
– via the operation keys on the electronics module ( ä 13, "Function of the operating

elements")

– via the operating menu ( ä 28, "Position zero adjustment")

• General recommendations for routing the impulse piping can be found in DIN 19210
"Methods for measurement of fluid flow; differential piping for flow measurement devices" or
the corresponding national or international standards.

• Using a three-valve or five-valve manifold allows for easy commissioning, installation and
maintenance without interrupting the process.

• When routing the impulse piping outdoors, ensure that sufficient anti-freeze protection is
used, e.g. by using pipe heat tracing.

• Install the impulse piping with a monotonic gradient of at least 10%.

• Endress+Hauser offers a mounting bracket for installing on pipes or walls (see Operating
Instructions BA00383P).

5.2 Operation with an operating menu

5.2.1 Operation concept

The operation concept makes a distinction between the following user roles:

User role Meaning

Operator Operators are responsible for the devices during normal "operation". This is usually limited to reading process

values either directly at the device or in a control room. If the work with the devices extends beyond value
read-off tasks, the tasks involve simple, application-specific functions that are used in operation. Should an error
occur, these users simple forward the information on the errors but do not intervene themselves.

Service
engineer/
technician

Service engineers usually work with the devices in the phases following device commissioning.
They are primarily involved in maintenance and troubleshooting activities for which simple settings have to be
made at the device.
Technicians work with the devices over the entire life cycle of the product.
Thus, commissioning and advanced settings and configurations are some of the tasks they have to carry out.

Deltabar M PROFIBUS PA Operation

Endress+Hauser 15

5.2.2 Structure of the operating menu

Expert Experts work with the devices over the entire product life cycle, but their device requirements are often

extremely high. Individual parameters/functions from the overall functionality of the devices are required for this
purpose time and again.
In addition to technical, process-oriented tasks, experts can also perform administrative tasks (e.g. user
administration).
"Experts" can avail of the entire parameter set.

User role Meaning

User role Submenu Meaning/use

Operator Language Only consists of the "Language" parameter (000) where the operating language for the device is

specified.
The language can always be changed even if the device is locked.

Operator Display/operat. Contains parameters that are needed to configure the measured value display (selecting the

values displayed, display format, etc.).
With this submenu, users can change the measured value display without affecting the actual
measurement.

Service
engineer/
technician

Setup Contains all the parameters that are needed to commission measuring operations. This submenu

has the following structure:

• Standard setup parameters
A wide range of parameters, which can be used to configure a typical application, is available
at the start. The measuring mode selected determines which parameters are available.
After making settings for all these parameters, the measuring operation should be completely
configured in the majority of cases.

• "Extended setup" submenu
The "Extended setup" submenu contains additional parameters for more in-depth
configuration of the measurement operation to convert the measured value and to scale the
output signal.
This menu is split into additional submenus depending on the measuring mode selected.

Service
engineer/
technician

Diagnosis Contains all the parameters that are needed to detect and analyze operating errors. This

submenu has the following structure:

• Diagnostic list
Contains up to 10 error messages currently pending.

• Event logbook
Contains the last 10 error messages (no longer pending).

• Instrument info
Contains information on the device identification.

• Measured values
Contains all the current measured values

• Simulation
Is used to simulate pressure, level, flow and alarm/warning.

• Factory reset

5.2.3 Operation with a device display (optional)

A 4-line liquid crystal display (LCD) is used for display and operation. The onsite display shows
measured values, dialog texts, fault messages and notice messages.
For easy operation the display can be taken out of the housing (see figure steps 1 to 3). It is
connected to the device through a 90 mm (3.54 in) cable.
The display of the device can be turned in 90° stages (see figure steps 4 to 6).
Depending on the orientation of the device, this makes it easy to operate the device and read the
measured values.

P01-Mxxxxxxx-19-xx-xx-xx-008

Expert Expert Contains all the parameters of the device (including those in one of the submenus). The "Expert"

submenu is structured by the function blocks of the device. It thus contains the following
submenus:

• System
Contains general device parameters that neither affect measurement nor integration into a
distributed control system.

• Measurement
Contains all the parameters for configuring the measurement.

• Communication
Contains the parameters of the PROFIBUS PA interface.

• Application
Contains all the parameters for configuring the functions that go beyond the actual
measurement (e.g. totalizer).

• Diagnosis
Contains all the parameters that are needed to detect and analyze operating errors.

5.3 Device identification and addressing

Please note the following:

• An address must be assigned to each PROFIBUS PA device. The control system/master can
only recognize the device if the address is set correctly.

• Each address can only be assigned once in any PROFIBUS PA network.

• Device addresses in the range from 0 to 125 are valid.

• The address "126" configured at the factory can be used for functional device testing and to
connect to a PROFIBUS PA network already in operation. This address must be changed
subsequently to add additional devices.

• On leaving the factory, all devices are delivered with the default address 126 and software
addressing.

• The FieldCare operating program is delivered with the default address 1.

There are two ways to assign the device address to a Deltabar:

• Via an operating program of the DP Class 2 master, such as FieldCare or

• Onsite via DIP switches.

7.6 Flow measurement

7.6.1 Information 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
elements such as pitot tubes or orifice plates and depends on the volume or mass flow. Four flow
types are available: volume flow, norm volume flow (European norm conditions), standard
volume flow (American standard conditions), mass flow and flow in %.

In addition, the Deltabar M software provides two totalizers as standard. The totalizers
integrates 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.

!

Note!
The totalizers are not available for the flow type "Flow in %".

7.7.3 "In pressure" level selection
Calibration without reference pressure (dry calibration)

Example:

In this example, the volume in a tank should be measured in liters. The maximum volume of
1000 liters (264 gal) corresponds to a pressure of 450 mbar (6.53 psi). The minimum volume of
0 liters corresponds to a pressure of 50 mbar (0.72 psi) since the device is mounted below the
start of the level measuring range.

Prerequisite:

• The measured variable is in direct proportion to the pressure.

• This is a theoretical calibration i.e. the pressure and volume values for the lower and upper
calibration point must be known.

!

Note!

• The values entered for "Empty calib. (028)/Full calib. (031)", "Empty pressure (029)/Full
pressure (032)" must be at least 1% apart. The value will be rejected, and a warning message
displayed, 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.

• Due to the orientation of the device, there may be pressure shifts in the measured value, i.e.
when the container is empty or partly filled, the measured value is not zero. For information
on how to perform position adjustment, see  ä 28, "Position zero adjustment".

7.7.4 "In height" level selection

Calibration without reference pressure (dry calibration)

Example:

In this example, the volume in a tank should be measured in liters. The maximum volume of
1000 liters (264 gal) corresponds to a level of 4.5 m (14.8 ft). The minimum volume of 0 liters
corresponds to a level of 0.5 m (1.6 ft) since the device is mounted below the start of the level
measuring range.

Prerequisite:

• The measured variable is in direct proportion to the pressure.

• This is a theoretical calibration i.e. the height and volume values for the lower and upper
calibration point must be known.

!

Note!

• The values entered for "Empty calib. (028)/Full calib. (031)", "Empty height (030)/Full height
(033)" must be at least 1% apart. The value will be rejected, and a warning message displayed,
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.
