7AF Password Security
10/11/99 Ken Hill & Steve Jacobson
Purpose
This document discusses the operation of the password system on the Model 7AF Back Grinder. Passwords are
an optional feature for the 7AF, implemented since version 3.00 software. The default is for no passwords to be
required. There are three levels of security available for operation of the grinder and one level for supervisory
administration of the passwords with a stand alone program.
Overview
The philosophy of security on the 7AF is to provide protection to the different access levels similar to having a
padlocked room. Also, accountability is handled by providing secret Identification Codes for users. Each access
level or Identification Code is accessed with a 4 character alphanumeric code entered on the touch screen. No
keyboard is required.
To use the machine at a given access level, an individual must know an authorized Identification Code and the
security code for the access level desired. This allows any individual to set the appropriate access level for the
actions they plan to take.
If the machine has the GEM option, security can be monitored and passwords can be maintained remotely.
Remote functions allow determining the current security state, the authorized user’s code, and any unauthorized
attempts to set passwords.
The stand alone password maintenance program is protected by a separate password to limit this supervisory
function. It allows a supervisor to view all passwords on a single screen and make changes through a keyboard,
instead of the machine’s touch screen interface. Entries are checked as they are made and the whole password
set is checked to insure that it can be down loaded via GEM. Password files can be downloaded and uploaded
similar to recipes if file size limitations are observed.
Setting Password Security
When Machine Variable #53 is changed to a non-zero value, this feature is enabled. Do not set this until
passwords have been set up! You will not be able to disable this function without assistance if you do not
know the maintenance or process engineering level password! Setting the variable to zero (or leaving it at
the default value of zero) allows the machine to operate as it has in the past, without access restrictions.
The machine is set with default codes to get started. You should change these immediately to your own codes.
The default Identification Code is: OPER First Code
The default passwords are:
Operator Level OPER
Process Engineer Level PROC
Maintenance Level MAIN
Supervisor Level SUPR
