ACCESS CODE
(2020)
All data of the measuring system are protected against inadvertent change.
Programming is disabled and the settings cannot be changed until a code is entered in
this function.
If you press the O/S keys in any function, the measuring system automatically goes to
this function and the prompt to enter the code appears on the display (when
programming is disabled).
You can enable programming by entering your personal code (factory setting = 83,
see function DEFINE PRIVATE CODE (2021)).
User input:
Max. 4-digit number: 0 to 9999
! Note!
• The programming levels are disabled if you do not press a key within 60 seconds
following automatic return to the HOME position.
• You can also disable programming in this function by entering any number (other
than the defined private code).
• The Endress+Hauser service organization can be of assistance if you mislay your
personal code.
• In this function, access to programming is only valid for local configuration. If
functions or parameters are to be changed via the fieldbus, programming must be
enabled separately in the parameter "Access - code" ( → Page 114).
