Chapter 8 Features
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 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 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 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 feature may be used to accomplish this:
Changing Security Levels:

onds.
CUst

fCty

play.
3. Press the Advance Key until Lock Operations prompt

play.
6. Press the Down

With the above settings, the Home Page and the Profiling Page can be accessed, and all writable pa-
rameters 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).
