die set-up personnel. A press operator is assigned a user name and password. With the password the
operator can reset tonnage monitor faults, reset die protection faults, and reset counters. These are the only
three items to which the operator has access. In order to load a die, the set-up personnel must use the
Program/Run key to recall a job from job storage. The set-up personnel will also be able to make changes
to programmable limit switch settings, tonnage monitor settings, and die protection settings. Once the set-up
personnel sets the die and verifies its correct operation, the operator is left to run the die. If a tonnage
monitor fault occurs, the operator can enter the correct password and then reset the fault. However, the
operator cannot change a tonnage monitor limit. This will allow the operator to keep running the job and
reset faults that occur. However, if consistent stops occur because a tonnage monitor high setpoint is being
exceeded, the set-up personnel must be called to change the tonnage monitor limit, if it has been determined
that the limit should be increased.
The example above can be taken one additional step, if two press operators are given different user names
and different passwords. One operator can be assigned the ability to change tonnage monitor limits in
addition to the ability to reset the tonnage monitor, while the other operator is not assigned the ability to
change the tonnage monitor limits. The control will allow for sixteen users each with a user name, password,
and access to selected or all restricted items.
Section 3.1.3 Password Only Mode
The “Password Only” mode allows for sixteen users. Each user can be assigned access to some or all of the
restricted items. This mode does not use the Program/Run key.
The example listed above indicated that setup personnel required access to all restricted parameters. In the
“Key or Password” mode, the setup personnel used the Program/Run key to gain access to all of the
restricted parameters. In the “Password Only” mode, the setup personnel can still have access to all of the
restricted parameters, but the system must be configured as such. The setup personnel must be assigned a
user name and password. In addition, all restricted items would be assigned access to the setup personnel.
Since there is no access to all restricted items with the Program/Run key, every restricted item must be
assigned to at least one user. If any restricted item is not assigned to at least one of the users, it cannot be
accessed. For example, if Erase Jobs is not assigned to at least one user, it will be impossible to perform the
erase job function. Access to the Erase Jobs must be assigned to at least one user, before the erase job
function can be performed.
Section 3.1.4 Key and Password Mode
The “Key and Password” mode requires the user to have the Program/Run key, user name, and user
password. Operation is basically the same as the Password only mode, except that in addition to entering
the password the user must switch the Program/Run key to the PROG position.
Since there is no access to all restricted items with the Program/Run key only, every restricted item must be
assigned at least one user. If any restricted item is not assigned to at least one of the users, it can never be
accessed.
