General notes

The Quick Setup menu (see Page 65) is adequate for commissioning with the necessary standard
settings. Complex measurement tasks on the other hand necessitate additional functions that you
can configure as necessary and customize to suit your process condition. 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 on Page 45.
• 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 OS 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.
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 functions are described in detail , including the function matrix itself, in the "Description of
Device Functions" manual, which is a separate part of these Operating Instructions.
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 = 90) 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 (→ see the "Description of Device Functions" manual).
Comply with the following instructions when entering codes:
• If programming is disabled and the OS keys 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 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 device, 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 the Endress+Hauser service organisation. Please
contact Endress+Hauser if you have any questions.
