Saving And Restoring User Settings
Recording setup and operations parameter settings
for future reference is very important. If you uninten-
tionally change these, you will need to program the
correct settings back into the controller to return the
equipment to operational condition.
After you program the controller and verify prop-
er operation, use User Save Set [USr;S] (Setup Page,
Global Menu) to save the settings into either of two
files in a special section of memory. If the settings in
the controller are altered and you want to return the
controller to the saved values, use User Restore Set
[USr;r]
(Setup Page, Global Menu) to recall one of
the saved settings.
Note:
Perform the above procedure when you are sure that
all the correct settings are programmed into the mod-
ule. Saving the settings overwrites any previously
saved collection of settings. Be sure to document all
of the module settings.
Using Lockout to Hide Pages and Menus
If unintentional changes to parameter settings might
raise safety concerns or lead to downtime, your can
use the lockout feature to make them more secure.
Each of the menus in the Factory Page and each
of the pages, except the Factory Page, has a security
level assigned to it. You can change the read and
write access to these menus and pages by using the
parameters in the Lockout Menu (Factory Page).
Lockout Menu
There are three parameters in the Lockout Menu
that can be used to restrict access to various menu's
in the RMA module that can be found in the Factory
Page, Security [`loC] Setting Menu:
• Lock Operations Page [LoC;o] sets the security lev-
el for the Operations Page (default: 2).
Note:
The Home and Setup Page lockout levels are fixed and
cannot be changed.
• Read Lockout Security [rLoC] determines which
pages can be accessed. The user can access the se-
lected level and all lower levels. (default: 5)
• Write Lockout Security [SLoC] determines which
parameters within accessible pages can be written
to. The user can write to the selected level and all
lower levels. (default: 5)
• Locked Access Level [loC;l] determines user level
menu visibility when an RUI is in use.
Note:
The menu lockout function applies only when an RUI
(optional hardware) is in use. This setting has no im-
pact when using EZ-ZONE Configurator software.
The table below represents the various levels of lock-
out for the Write Lockout Security prompt and the
Read Lockout Security prompt. The Write Lockout
has 6 levels (0-5) of security where the Read Lockout
has 5 (1-5). Therefore, level "0" applies to Set Lockout
only. "Y" equates to yes (can write/read) where "N"
equates to no (cannot write/read). The colored cells
simply differentiate one level from the next.

The following examples show how the Lockout Menu
parameters may be used in applications:
1. 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.
2. 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.
3. The operator wants to read the Operations Page,
Setup Page, Diagnostics Menu and the Lock
Menu. 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 Op-
erations Page [LoC;O] to 2.
Using Password Security
It is sometimes desirable to apply a higher level of
security to the module where a limited number of
menus are visible while not providing access to oth-
ers without a security password. Without the appro-
priate password those menus will remain inacces-
sible. If Password Enabled [pas;e] in the Factory
Page under the Lock [`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 pass-
word has visibility to are defined in the Locked Ac-
cess Level [loC;L] prompt. On the other hand, a user
