7 Operation options
7.1 Operation with an operating menu
7.1.1 Operating concept
Operation with an operating menu is based on an operation concept with "user roles" .
User role Meaning
Operator
(display level)
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. Should an error occur,
these users simple forward the information on the errors but do not intervene themselves.
Maintenance
(user level)
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.
7.2 Structure of the operating menu
The menu structure has been implemented according to VDMA 24574-1 and
complemented by Endress+Hauser-specific menu items.
User role Submenu Meaning/use
Operator (display
level)
Display/operat. Display of measured values, fault and information messages
Maintenance (user
level)
Parameters on
the topmost
menu level.
Contains all the parameters that are needed to commission
measuring operations. A wide range of parameters, which can be
used to configure a typical application, is available at the start. After
making settings for all these parameters, the measuring operation
should be completely configured in the majority of cases.
EF The submenu "EF" contains additional parameters which allow more
accurate configuration of the measurement, conversion of the
measured value and scaling of the output signal.
DIAG Contains all the parameters that are needed to detect and analyze
operating errors.

7.3 Operation with local display
7.3.1 Overview
A 1-line liquid crystal display (LCD) is used for display and operation. The local display
shows measured values, fault messages and information messages and therefore supports
the user through each operating step.
The display is fixed to the housing and the values can be rotated electronically by 180° (see
parameter description for "DRO" → 62). This ensures optimum readability of the local
display and allows the device to be mounted upside down also.
During measuring operation, the display shows measured values, fault messages and
notice messages. In addition, it is possible to switch to menu mode via the operating keys.
