5 Operation Promag 53 PROFIBUS-DP/-PA
68 Endress+Hauser
General notes
A few parameters must be entered for the commissioning (see Commissioning
Page 86). 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 func-
tions 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 on Page 67. Each cell in the function matrix is iden-
tified 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
to select
“SURE [ YES ]” and then press
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.
Note:
• The transmitter continues to measure while data entry is in progress, i.e. the current
measured values are output via the signal outputs in the normal way.
• If the power supply fails, all preset and parameterised values remain safely stored in
the EEPROM.
Caution:
All of the functions are described in detail, including the function matrix itself, in the
“Description of Device Functions” manual, which is a separate part of this Operating
Instruction!
Enabling the programming mode
The function matrix can be disabled. Disabling the function matrix rules out the possi-
bility of inadvertent changes to device functions, numerical values or factory settings.
You must first enter a numerical code (factory setting = 53) before you can change the
settings. If you use a code number of your choice, you exclude the possibility of unau-
thorised persons accessing data (
→ see the “Description of Device Functions”
manual).
Comply with the following instructions when entering codes:
• If programming is disabled and the
keys are pressed in any function, a prompt for
the code will appear automatically on the display.
• If “0” is entered as the customer's code, programming is always enabled.
• The E+H service organisation 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 conse-
quently, they are protected by a special code known only to the E+H service organisa-
tion. Please contact Endress+Hauser if you have any questions.
