Section 3 Access Control
Section 3.1 Description
The OmniLink control has several parameters or operations that have limited access. The ability to perform
actions such as job recall, job storage, or changing a tonnage monitor channel limits must be restricted to
certain personnel. The OmniLink control provides several means to limit access to these parameters or
operations. A complete list of the parameters and operations that have limited access is listed in Section 3.2.
The items in Section 3.2 are called restricted items.
In addition to the restricted items listed in Section 3.2, there are other parameters that have limited access.
These parameters, such as top stop angles and brake monitor settings, are not listed in the table of restricted
items. These other items are called configuration parameters. Access to the configuration parameters is
protected by the Program/Run key and the Configuration code. Configuration parameters and their
programming are described in Section 5 of this manual. Access control will grant access only to the items
listed in Section 3.2.
The OmniLink control employs combinations of two different means to limit access to restricted items. These
means are the Program/Run key switch and a user password system. The user password system assigns
names and passwords to up to sixteen users. These two means can be used alone or in combination with each
other. When a user employs the proper means to gain access control, he will have the ability to perform the
actions and change the parameters which have been designated to his access.
There are four possible modes of operation for the restricted access system. They are the “Key Only” mode,
the “Key or Password” mode, the “Password Only” mode, and the “Key and Password” mode. The control
can be configured to operate in any one of these four modes.
Section 3.1.1 Key Only Mode
The “Key Only” mode is the least complex of the four modes. This mode employs the Program/Run key as
the only means to limit access to restricted items. Any user with the Program/Run key can access all of the
restricted items. Without the Program/Run key, user access to all of the restricted items is prohibited.
Although the “Key Only” mode has the advantage of being easy to use, it does have a disadvantage. This
mode cannot give a particular user access to only some of the restricted items. When operating in this mode,
any user with the Program/Run key will have access to all of the restricted items.
Section 3.1.2 Key or Password Mode
The key or password mode allows for either of two means to gain access to the restricted items. A user with
Program/Run key can access all of the restricted items. A user with the correct password can access the
restricted items that have been designated for the particular user’s access only. The system allows for
passwords to be assigned to sixteen users. Each user can be assigned access to any or all of the restricted
items.
The following is an example of a “Key or Password” mode operation. The Program/Run key is given to the
