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 required 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, specied menus will remain inaccessible. Page and Menu access
is dened in the Locked Access Level LoC.L prompt. On the other hand, a User with a pass-
word 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 dened by level 3 access.
How to Enable Password Security
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 Password Enable PAS.E appears in the bottom display and
change it to 5.
4. Press the Up Key ¿ to turn it
on
. Once on, four new prompts will appear:
a. Locked Access Level LoC.L, (1 to 5) corresponding to the lockout table above.
b. Rolling Password roLL, will change the Customer Code every time power is cycled.
c. User Password pas.u, which is needed for a User to acquire access to the control.
d. Administrator Password pas.A, which is needed to acquire administrative access to
the control.
The Administrator can either change the User and or the Administrator password or leave
them in the default state. Once Password Security is enabled they will no longer be visible to
anyone other than the Administrator. In other words the Lock Menu
LoC
is not available to a
User. As can be seen in the formula that follows either the User or Administrator will need to
