Operation Promag 53 PROFIBUS DP/PA
72 Endress+Hauser
5.3.1 General notes
The Quick Setup menu contains the default settings that are adequate for commissioning.
Complex measuring operations on the other hand necessitate additional functions that you
can configure as necessary and customize to suit your process parameters. The function
matrix, therefore, comprises a multiplicity of additional functions which, for the sake of
clarity, are arranged on a number of menu levels (blocks, groups, and function groups).
Comply with the following instructions when configuring functions:
• You select functions as described → 71.
Each cell in the function matrix is identified by a numerical or letter code on the display.
• You can switch off certain functions (OFF). If you do so, related functions in other function
groups will no longer be displayed.
• Certain functions prompt you to confirm your data entries. Press
O
/
S
to select
"SURE [ YES ]" and press
F
again to confirm. This saves your setting or starts a function, as
applicable.
• Return to the HOME position is automatic if no key is pressed for 5 minutes.
• Programming mode is disabled automatically if you do not press a key within 60 seconds
following automatic return to the HOME position.
"
Caution!
All functions are described in detail, as is the function matrix itself, in the "Description of
Device Functions" manual which is a separate part of this Operating Manual.
!
Note!
• The transmitter continues to measure while data entry is in progress, i.e. the current
measured values are output via the signal outputs or the fieldbus communication in the
normal way.
• If the supply voltage fails, all preset and configured values remain stored safely in the
EEPROM.
5.3.2 Enabling the programming mode
The function matrix can be disabled. Disabling the function matrix rules out the possibility
of inadvertent changes to device functions, numerical values or factory settings. A numerical
code (factory setting = 53) has to be entered before settings can again be changed.
If you use a code number of your choice, you exclude the possibility of unauthorized persons
accessing data ( see the "Description of Device Functions" manual).
Comply with the following instructions when entering codes:
• If programming is disabled and the
OS
operating elements are pressed in any function, a
prompt for the code automatically appears on the display.
• If "0" is entered as the customer's code, programming is always enabled.
• The Endress+Hauser service organization can be of assistance if you mislay your personal
code.
"
Caution!
Changing certain parameters such as all sensor characteristics, for example, influences
numerous functions of the entire measuring system, particularly measuring accuracy.
There is no need to change these parameters under normal circumstances and consequently,
they are protected by a special code known only to Endress+Hauser. Please contact your
Endress+Hauser service organization if you have any questions.
5.3.3 Disabling the programming mode
Programming mode is again disabled if you do not press an operating element within 60
seconds following automatic return to the HOME position.
You can also disable programming in the "ACCESS CODE" function by entering any number
(other than the customer's code).
