Explanation
1 OPL The OPL (over pressure limit = sensor overload limit) for the measuring device
depends on the lowest-rated element, with regard to pressure, of the selected
components, i.e. the process connection has to be taken into consideration in
addition to the measuring cell. Also observe pressure-temperature dependency.
For the relevant standards and additional notes, see the "Pressure specifications"
section .
The OPL may only be applied for a limited period of time.
2 MWP The MWP (maximum working pressure) for the sensors depends on the lowest-
rated element, with regard to pressure, of the selected components, i.e. the
process connection has to be taken into consideration in addition to the
measuring cell. Also observe pressure-temperature dependency. For the
relevant standards and additional notes, see the "Pressure specifications"
section .
The MWP may be applied at the device for an unlimited period.
The MWP can also be found on the nameplate.
3 Maximum sensor
measuring range
Span between LRL and URL
This sensor measuring range is equivalent to the maximum calibratable/
adjustable span.
4 Calibrated/
adjusted span
Span between LRV and URV
Factory setting: 0 to URL
Other calibrated spans can be ordered as customized spans.

2 Zero point-based span
3 URL sensor
Example
• Sensor:10 bar (150 psi)
• Upper range value (URL) = 10 bar (150 psi)
Turn down (TD):
• Calibrated/adjusted span: 0 to 5 bar (0 to 75 psi)
• Lower range value (LRV) = 0 bar (0 psi)
• Upper range value (URV) = 5 bar (75 psi)
TD = URL
|URV - LRV|
TD = 10 bar (150 psi) = 2
|5 bar (75 psi) - 0 bar (0 psi)|
In this example, the TD is 2:1.
This span is based on the zero point.

2 Operation options
2.1 Operation with an operating menu
2.1.1 Operation concept
Operation with an operating menu is based on an operation concept with "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, applicationspecific
functions that are used in operation. Should an error occur, these users simply forward the
information on the errors but do not intervene themselves.
Maintenance 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.
Expert Experts work with the devices over the entire life cycle of the device, but, at times, have high
device requirements. 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
access the entire parameter set.
2.2 Structure of the operating menu
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, display contrast, etc.). With this
submenu, users can change the measured value display without affecting the actual
measurement.
Maintenance 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 indepth
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.

Operation options Deltabar FMD71, FMD72
10 Endress+Hauser
User role Submenu Meaning/use
Maintenance 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, current and alarm/warning.
•Reset
•Sensor LP
•Sensor HP
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 all the device parameters that neither affect measurement nor
integration into a distributed control system.
•Measurement
Contains all the parameters for configuring the measurement.
•Output
Contains all the parameters for configuring the current output.
•Communication
contains all parameters for configuring the HART interface.
•Diagnosis
Contains all the parameters that are needed to detect and analyze operating
errors.
2.3 Operating options
2.3.1 Local operation

A0017650
1 Display and operating module with push buttons. Cover must be opened for operation.
2.4 Operating the device using onsite display (optional)
A 4-line liquid crystal display (LCD) is used for display and operation. The onsite display
shows measured values, dialog text as well as fault and notice messages in plain text,
thereby supporting the user in every stage of operation.
The display can be removed for easy operation.
The device display can be turned in 90° steps.
Depending on the installation position of the device, this makes it easy to operate the
device and read the measured value.
