Proline Prowirl 73 Operation
Endress+Hauser 37
5.2.1 General notes
The Quick Setup menu (ä 109 and ä 51) is adequate for commissioning with the necessary
standard settings. 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 in a number of function groups.
Comply with the following instructions when configuring functions:
• You select functions as described (ä 36).
• You can switch off certain functions (OFF). If you do so, related functions in other function groups
will no longer be displayed.
• If an unassignable option is selected in the ASSIGN LINE 1 or ASSIGN LINE 2 function for the
fluid selected (e.g. corrected volume flow option is selected for saturated steam), "– – – –" appears
on the display.
• Certain functions prompt you to confirm your data entries. Press OS to select "SURE [ YES ]" and
press the F key 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 automatically disabled if you do not press a key within 60 seconds
following return to the HOME position.
!
Note!
• All functions are described in detail, as is the function matrix itself on ä 95.
• 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 configured values remain safely stored in the EEPROM.
5.2.2 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 = 73) has to be entered before settings can be changed. If you use
a code number of your choice, you exclude the possibility of unauthorized persons accessing data.
Function ACCESS CODE Page 110.
Comply with the following instructions when entering codes:
• If programming is disabled and the
P
key combination is pressed in any function, a prompt for
the code automatically appears on the display.
• If "0" is entered as the private code, programming is always enabled.
• Your Endress+Hauser service organization can be of assistance if you mislay your private code.
5.2.3 Disabling the programming mode
Programming is disabled if you do not press a key within 60 seconds following automatic return to
the HOME position.
You can also disable programming by entering any number (other than the private code) in the
ACCESS CODE function.
