1.2.2 Menu structure
1.2.2.1 Password level
The access rights within the menu structure are protected by different passwords.
The operator is asked to enter a password when they try to enter a command.
The password consists of a 4-figure number.
Each password level has a different number allocated to it.
The passwords for Levels 1 to 8 can be freely allocated by the user.
The password for the highest password level 9 is specified by Grasso on delivery and cannot be subsequently
changed.
If a password is entered and then no key is used for a longer period (approx. 10 mins), the operator panel
automatically logs out from the password level.
