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

Structure of the operating menu
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.
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
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.
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 "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, current and alarm/warning.
•
Reset
