5.2.1
General notes
The brief commissioning guide (→ ä 39) is adequate for commissioning a standard set-up of the
transmitter. Complex measurement tasks require set-up by means of the function matrix, which
comprises an additional functions. 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:
• Select functions as described on → ä 29.
• Certain functions can be switched off (OFF). If functions are switched off related functions in
other function groups will no longer be displayed.
• Certain functions require confirmation of the data entries.
Press P to select "SURE [ YES ]" and press F again to confirm. The setting is saved 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 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 = 91) has to be entered before settings can be changed.
If the "private code" is activated, this excludes the possibility of unauthorized persons accessing data,
see ACCESS CODE function → ä 73.
Comply with the following instructions when entering codes:
• If programming is disabled and the P operating elements are pressed in any function, a prompt
for the code automatically appears on the display.
• If "0" is specified as the private code, programming is always enabled.
• The Endress+Hauser service organization can be of assistance if the personal code is lost.
Caution!
Changing certain sensor specific parameters may influence characteristics of numerous functions of
the entire measuring device, particularly measuring accuracy.
This type of parameters may not be changed! Please contact Endress+Hauser if you have any
questions.
5.2.3
Disabling the programming mode
Programming is disabled if the operating elements is not pressed within 60 seconds following a
return to the HOME position.
This programming is disable by entering any number in the function "ACCESS CODE" (any other
than the customer's code).
