Access Control - Siemens SITRANS FC430 Operating Instructions Manual

7.1.1.2

Access control

The user can view all parameters in the HMI menu but the parameters are protected against
changes with access level control. The user gains access when entering the navigation view
by selecting one of the following access levels.
● Read Only
Allows no configuration. The user is only able to view the parameter values. No PIN code
required.
● User
Allows configuration and service of all parameters except calibration parameters. Default
PIN code is 2457.
● Expert
Allows configuration and service of all parameters including flow and density calibration
parameters. Default PIN code is 2834.
PIN codes can be changed in menu 5 "Security".
The exact structure of the operating menu is explained in the HMI menu structure (Page 277).
Note
Lost PIN code
If the PIN code is lost, provide Siemens customer support with the transmitter serial number
(see nameplate). Siemens customer support will provide a code to be entered in Reset PINs
(menu item 5.1.3).
Disable access level control
If logged in as "Expert" you can "Disable Access Level Control" meaning that you will always
be logged in as "User" and will not be prompted to enter the password. Enabling the access
level control requires entering the "Expert" password.
