Security
Security can be used for the following three functions:
To control access to the Management menu
To write-protect the Series 3000 device configuration
To control how process totalizers and inventories can be reset
Note: If custody transfer is implemented, the write-protection and totalizer reset control functions are 
handled by the custody transfer application, and are not available here. See Chapter 14.
Note: If custody transfer (OIML) is implemented, you can also define an alarm log password to 
control access to the active alarm log, the alarm event log, and alarm history. See Chapter 14.
5.3.1
Management menu access
Access to the Management menu can be controlled by two passwords:
The configuration password enables access to all Management menus
The maintenance password enables access to the Maintenance portion of the Management 
menu system
When the Security button is pressed (see Section 4.3.1):
If security is enabled, you will be prompted to enter a password. Depending on the password 
you enter, either the Management menu or the Maintenance menu is displayed. 
If security is disabled, the Management menu is displayed immediately.
The configured passwords are stored even if security is disabled, so you can re-enable them at any 
time.
It is not possible to activate only the configuration password or only the maintenance password.
