Passwords must consist of 4 digits and be different for the 3 levels
6.7.43. Function 59 - Change access level
By entering function 59, the command line will prompt for a password.
Key in the 4 digits password from Function 58 for the desired access level for the operator and
press ENT.
Password protecting the MC12 is realised by establishing 3 Levels of operability from the
keyboard. The idea is to limit the number of functions and key's available to the operator. In
praxis the operator will have no response from the MC12, when trying to use functionality that
have been excluded in the current level.
When the MC12 is in Level 2 or 3 and parameters are to be changed or another programme to
be loaded, the supervisor must use Function 59 and key in the password for Level 1. Then
make the changes and use Function 59 again to put the MC12 back in Level 2 or 3.
