The table below represents the various levels of lockout for the Set Lockout Security prompt [SLoC] and
the Read Lockout Security prompt [rLoC]. Looking at the table, "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 while also
showing the level where read/write is enabled. As stated previously, the Set Lockout has 6 levels (0 to 5) of se-
curity where the Read Lockout has 5 (1 to 5). Therefore, level "0" applies to Set Lockout only.

Factory Page Y Y Y Y Y Y
Being able to change the page security level for the Operations and Profile pages allows a user to give access
to the Profile Page while locking out the Operations Page. The following example shows how the Lockout fea-
ture may be used to accomplish this:
1. Press and hold the Advance
‰
and Infinity ˆ keys for approximately 6 seconds to enter the Factory Page
2. Navigate to the [`LoC] Menu using the Up or Down arrow keys
3. Using the green Advance key navigate to the Lock Operations prompt [LoC;o] and change it (push the Up
arrow) from the default value of 2 to 3
4. Push the Advance key again and change the Lock Profiling prompt [LoC;P] from the default of 3 to 2
5. Change Read Lockout Security [rLoC] to 2 and the Set Lockout [SLoC] to 2 or higher
With the above settings, the Home Page and the Profiling Page can be accessed, and all writable param-
eters can be written to. Due to the Read lock setting of 2 all pages with security levels greater than 2 will be
locked out (inaccessible).
Another example of Method 1 lockout usage could be that an operator wants read access to all pages while al-
lowing read/write access to the Home Page and the Lockout Menu only.
1. Press and hold the Advance and Infinity keys for approximately 6 seconds to enter the Factory Page
2. Navigate to the [`LoC] Menu using the Up or Down arrow keys
3. Using the green Advance key navigate to the Read Lockout Security [rLoC] and change it to 5
4. Push the green Advance key and navigate to the and Set Lockout Security [SLoC] changing it to 1
Although the Factory Page is always visible, some menus within it can be restricted.

(not writable) with two exceptions, [sloC] and [rloC]. As shown below, both of these parameters can al-
ways be seen and modified.
