1 OPL: The OPL (overpressure limit = measuring cell overload limit) for the 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. Pay attention to the pressure/temperature dependency.
2 The MWP (maximum working pressure) for the measuring cells 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. Pay attention to the pressure/temperature dependency. The MWP may be
applied at the device for an unlimited period of time. The MWP can be found on the nameplate.
3 The maximum measuring range corresponds to the span between the LRL and URL. This measuring range is
equivalent to the maximum calibratable/adjustable span.
4 The calibrated/adjusted span corresponds to the span between the LRV and URV. Factory setting: 0 to URL.
Other calibrated spans can be ordered as customized spans.

‣Being instructed and authorized according to the requirements of the task by the
facility's owner-operator
‣Following the instructions in these Operating Instructions
2.2 Intended use
The Deltabar is a differential pressure transmitter for measuring pressure, flow, level and
differential pressure.
2.2.1 Incorrect use
The manufacturer is not liable for damage caused by improper or non-intended use.
Verification for borderline cases:
‣For special fluids and fluids for cleaning, Endress+Hauser is glad to provide assistance
in verifying the corrosion resistance of fluid-wetted materials, but does not accept any
warranty or liability.

Deltabar PMD78B PROFINET with Ethernet-APL Basic safety instructions
Endress+Hauser 9
‣Use original spare parts and accessories from Endress+Hauser only.
Hazardous area
To eliminate the risk of danger to persons or the facility when the device is used in the
approval-related area (e.g. explosion protection, pressure equipment safety):
‣Check the nameplate to verify if the device ordered can be put to its intended use in the
approval-related area.
‣Observe the specifications in the separate supplementary documentation that is an
integral part of these Instructions.
2.5 Product safety
This device is designed in accordance with good engineering practice to meet state-of-the-
art safety requirements, has been tested, and left the factory in a condition in which it is
safe to operate.
It meets general safety standards and legal requirements. It also complies with the EC
directives listed in the device-specific EC Declaration of Conformity. Endress+Hauser
confirms this by affixing the CE mark to the device.
2.6 IT security
Endress+Hauser can only provide a warranty if the device is installed and used as
described in the Operating Instructions. The device is equipped with security mechanisms
to protect it against any inadvertent changes to the device settings. IT security measures in
line with operators' security standards and designed to provide additional protection for
the device and device data transfer must be implemented by the operators themselves.
2.7 Device-specific IT security
The device offers specific functions to support protective measures by the operator. These
functions can be configured by the user and guarantee greater in-operation safety if used
correctly. An overview of the most important functions is provided in the following section:
• Write protection via hardware write protection switch
• Access code to change the user role (applies for operation via display, Bluetooth, or
FieldCare, DeviceCare, Asset Management Tools (e.g. AMS, PDM and web server)
Function/interface Factory setting Recommendation
Access code
(also applies for web server login or
FieldCare connection)
Not enabled
(0000)
Assign a customized access code during
commissioning.
Web server Enabled On an individual basis following risk assessment.
Service interface (CDI) Enabled On an individual basis following risk assessment.
Write protection via hardware write
protection switch
Not enabled On an individual basis following risk assessment.
2.7.1 Protecting access via a password
Different passwords are available to protect write access to the parameters of the device.
Protect write access to the parameters of the device via the local display, web browser or
operating tool (e.g. FieldCare, DeviceCare). Access authorization is clearly regulated
through the use of a user-specific access code.

Basic safety instructions Deltabar PMD78B PROFINET with Ethernet-APL
10 Endress+Hauser
User-specific access code
Write access to the parameters of the device via the local display, web browser or
operating tool (e.g. FieldCare, DeviceCare) can be protected using the editable, user-
specific access code.
When the device is delivered, the device does not have an access code and is equivalent to
0000 (open).
General notes on the use of passwords
• During commissioning, change the access code that was used when the device was
delivered from the factory
• When defining and managing the access code, comply with the general rules for the
generation of a secure password
• The user is responsible for managing the access code and for using the code with due
care
• If the password is lost, see the "Resetting the device" section
2.7.2 Access via web server
Due to the integrated web server, the device can be operated and configured via a web
browser and PROFINET with Ethernet-APL. In addition to the measured values, device
status information is also displayed, allowing users to monitor the status of the device.
Furthermore the device data can be managed and the network parameters can be
configured.
Access to the network is required for the PROFINET with Ethernet-APL connection.
Supported functions
Data exchange between the operating unit (such as a notebook for example) and the
measuring device:
• Export parameter settings (PDF file, create documentation of the measuring point
configuration)
• Export the Heartbeat Technology verification report (PDF file, only available with the
"Heartbeat Verification" application package)
• Download driver (GSDML) for system integration
The web server is enabled when the device is delivered. The web server can be disabled via
the Web server functionality parameter if necessary (e.g. after commissioning).
The device and status information can be hidden on the login page. This prevents
unauthorized access to the information.
