The following examples show how the Lockout Menu
parameters may be used in applications:
1. You can lock out access to the Operations Page
but allow an operator access to the Profile Menu,
by changing the default Profile Page and Opera-
tions Page security levels. Change Lock Opera-
tions Page [LoC;o] to 3 and Lock Profiling Page
[LoC;P]
to 2. If Set Lockout Security [SLoC] is
set to 2 or higher and the Read Lockout Security
[rLoC]
is set to 2, the Profiling Page and Home
Pages can be accessed, and all writable param-
eters can be written to. Pages with security levels
greater than 2 will be locked out (inaccessible).
2 If Set Lockout Security [SLoC] is set to 0 and
Read Lockout Security [rLoC] is set to 5, all
pages will be accessible, however, changes will
not be allowed on any pages or menus, with one
exception: Set Lockout Security [SLoC] can be
changed to a higher level.
3. The operator wants to read all the menus and not
allow any parameters to be changed.
In the Factory Page, Lockout Menu, set Read
Lockout Security [rLoC] to 5 and Set Lockout
Security [SLoC] to 0.
4. The operator wants to read and write to the
Home Page and Profiling Page, and lock all other
pages and menus.
In the Factory Page, Lockout Menu, set Read
Lockout Security [rLoC] to 2 and Set Lockout
Security [SLoC] to 2.
In the Factory Page, Lockout Menu, set Lock
Operations Page [LoC;O] to 3 and Lock Profiling
Page [LoC;P] to 2.
5. The operator wants to read the Operations
Page, Setup Page, Profiling Page, Diagnostics
Menu, Lock Menu, Calibration Menu and Cus-
tom Menus. The operator also wants to read and
write to the Home Page.
In the Factory Page, Lockout Menu, set Read
Lockout Security [rLoC] to 1 and Set Lockout
Security [SLoC] to 5.
In the Factory Page, Lockout Menu, set Lock
Operations Page [LoC;O] to 2 and Lock Profiling
Page [LoC;P] to 3.
Using Password Security
It is sometimes desirable to apply a higher level of
security to the control where a limited number of
menus are visible and not providing access to others
without a security password. Without the appropri-
ate password those menus will remain inaccessible.
If Password Enabled [pas;e] in the Factory Page
under the [`loC] Menu is set to on, an overriding
Password Security will be in effect. When in effect,
the only Pages that a User without a password has
visibility to are defined in the Locked Access Level
[ loC;L]
prompt. On the other hand, a User with a
password would have visibility restricted by the Read
Lockout Security [rloC]. As an example, with Pass-
word Enabled and the Locked Access Level [loC;L]
set to 1 and [rloC] is set to 3, the available Pages
for a User without a password would be limited to
the Home and Factory Pages (locked level 1). If the
User password is entered all pages would be acces-
sible with the exception of the Setup Page as defined
by level 3 access.
How to Enable Password Security
Go to the Factory Page by holding down the Infinity
ˆ
key and the Advance
‰
key for approximately six
seconds. Once there, push the Down ¯ key one time
to get to the [`loC] menu. Again push the Advance
‰
key until the Password Enabled [pas;e] prompt
is visible. Lastly, push either the up or down key to
turn it on. Once on, 4 new prompts will appear:
1. [loC;l] , Locked Access Level (1 to 5) correspond
ing to the lockout table above.
2. [roll] , Rolling Password will change the Cus-
tomer Code every time power is cycled.
3. [pas;u] , User Password which is needed for a Us-
er to acquire access to the control.
4. [pas;a] , Administrator Password which is need-
ed to acquire administrative access to the control.
The Administrator can either change the User and
or the Administrator password or leave them in the
default state. Once Password Security is enabled they
will no longer be visible to anyone other than the
Administrator. As can be seen in the formula that
follows either the User or Administrator will need to
know what those passwords are to acquire a higher
level of access to the control. Back out of this menu
by pushing the Infinity ˆ key. Once out of the menu,
the Password Security will be enabled.
How to Acquire Access to the Control
To acquire access to any inaccessible Pages or
Menus, go to the Factory Page and enter the [UloC]
menu. Once there follow the steps below:
