Using Lockout and Password Security
If unintentional changes to parameter settings might raise safety concerns or lead to down-
time, you can use the lockout feature to make them more secure. There are two methods of
lockout that can be deployed, both of which are accessible from the Factory Page.
Method 1- Change the value of the Read Lock rLoC (1 to 5) and Set Lock sLoC (0 to 5)
prompts where the higher the value or setting for each translates to a higher
security clearance (greater access).
Method 2- Enable Password Security pas.E and then modify the Lock Level LoC.L value
which ranges from 1 to 5. See the section entitled Using Lockout Method 2 for
more detail.
Using Lockout Method 1 (Read and Set Lock)
All Pages have security levels assigned where two of those cannot be changed (Home and
Setup). Defaults (factory settings) for each are shown below:
- Home Page = 1
- Operations Page = 2 (changeable to 1, 2 or 3)
- Setup Page = 4
- Profiling Page = 3 (changeable to 1, 2 or 3)
- Factory Page = 5*
* The Factory Page is always visible where all menus within it may or may not be visible/
writable. For further detail see table "Factory Page Menus".
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 dif-
ferentiate 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 security where the Read Lockout
has 5 (1 to 5). Therefore, level "0" applies to Set Lockout only.

Being able to change the page security level for the Operations and Prole pages allows a
user to give access to the Prole Page while locking out the Operations Page. The following
example shows how the Lockout feature may be used to accomplish this:
Changing Security Levels:
1. From the Home Page, press and hold the Innity Key ˆ and the Advance Key ‰ for ap-
proximately six seconds. CUst will appear in the upper display and fCty will appear in the
lower display.
2. Press the Up Key ¿ until LoC appears in the upper display and fCty will appear in the
lower display.
