With the above settings, the Home Page and the Proling Page can be accessed, and all writ-
able parameters 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 allowing read/write access to the Home Page and the Lockout Menu only. To
setup this scenario follow the steps below:
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.
3. Press the Advance Key ‰ until Read Lock rLoC appears in the bottom display and change it
to 5.
4. Press the Advance Key ‰ until Set Lock SLoC appears in the bottom display and change it to
1.
