Note:
Using Method 1 Lockout all settings can be modified by anyone who knows how to find their way to the
[SLoC] and [rloC] parameters
Using Lockout Method 2 (Password Enable)
It is sometimes desirable to apply a higher level of security to the control where a password would be re-
quired to access the control. If Password Enabled [pas;e] in the Factory Page under the [`loC] Menu is
set to on, an overriding Password Security will be in effect. Without the appropriate password, specified
menus will remain inaccessible. Page and Menu access is defined in the Locked Access Level [loC;L] prompt.
On the other hand, a User with a password would have visibility restricted by the Read Lockout Security
[rloC]. As an example, with Password Enabled and the Locked Access Level [loC;L] set to 1 and [rloC] is
set to 3, the available Pages for a User without a password would be limited to the Home and Factory Pages
(locked level 1). If the User password is entered all pages would be accessible with the exception of the Setup
Page as defined by level 3 access.
How to Enable Password Security
Follow the steps below:
1. Go to the Factory Page by holding down the Infinity ˆ key and the Advance
‰
key for approximately six
seconds.
2. Push the Down ¯ key one time to get to the [`loC] menu. Again push the Advance
‰
key until the Pass-
word Enabled [pas;e] prompt is visible.
3. Push either the up or down key to turn it on. Once on, 4 new prompts will appear:
1. [loC;l] , Locked Access Level (1 to 5) corresponding to the lockout table above.
2. [roll] , Rolling Password will change the Customer Code every time power is cycled.
3. [pas;u], User Password which is needed for a User to acquire access to the control.
4. [pas;a], Administrator Password which is needed to acquire administrative access to the control.
