Programming the EZ Key/s
You can program the EZ Key either in the Setup Menu or with configuration software, such as EZ-ZONE
Configurator, using a personal computer.
The following examples show how to program the EZ Key to start and stop a profile.
Using keys and display:
1. To go to the Setup Page from the Home Page, press both the Up ¿ and Down ¯ keys for six seconds. [``Ai]
will appear in the upper display and [`Set] will appear in the lower display.
2. Press the Up Key ¿ until [`Fun] appears in the upper display and [`SEt] will appear in the lower display.
3. Press the Advance Key
‰
until Digital Input Level [`leu] appears in the lower display. Use an arrow key
to specify the state of the key (high or low) when the controller is powered up. Functions will toggle with each
press of the EZ Key, such as Profile Start/Stop.
4. Press the Advance Key
‰
. The lower display will show Digital Function [``Fn]. Press the Up ¿ or Down
¯ key to scroll through the functions that can be assigned to the EZ Key
When Profile Start/Stop [P;StS] appears in the upper display and [``Fn] appears in the lower display,
press the Advance Key ‰ once to select that function and move to the Function Instance [``FS] param-
eter.
5. Press the Up ¿ or Down ¯ key to scroll to the profile that you want the EZ Key to control.
6. The instance tells the controller which of the numbered functions should be acted upon. For profiles,
there are 4 instances. Press the Infinity Key ˆ once to return to the submenu, twice to return to the
main menu or three times to return to the Home Page.
Using Lockout and Password Security
If unintentional changes to parameter settings might raise safety concerns or lead to downtime, 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 fur-
ther detail see table "Factory Page Menus".
