PM Integrated Controller 141 • Chapter 9 Features
The Administrator can either change the User and or the Administrator password or leave them in the de-
fault state. Once Password Security is enabled they will no longer be visible to anyone other than the Ad-
ministrator. 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 know what those passwords are to acquire a high-
er level of access to the control. Back out of this menu by pushing the Infinity ˆ key. Once out of the menu,
the Password Security will be enabled.
How to Acquire Access to the Control
To acquire access to any inaccessible Pages or Menus, go to the Factory Page and enter the [UloC] menu.
Once there follow the steps below:
Note:
If Password Security (Password Enabled [pas;e] is On) is enabled the two prompts mentioned below in
the first step will not be visible. If the password is unknown, call the individual or company that originally
setup the control.
1. Acquire either the User Password [pas;u] or the Administrator Password [pas;a].
2. Push the Advance
key one time where the Code [Code] prompt will be visible.
Note:
a. If the the Rolling Password is off push the Advance key one more time where the Password [pass]
prompt will be displayed. Proceed to either step 7a or 8a. Pushing the Up ¿ or Down ¯ arrow keys enter
either the User or Administrator Password. Once entered, push and hold the Infinity ˆ key for two sec-
onds to return to the Home Page.
b. If the Rolling Password [roll] was turned on proceed on through steps 3 - 9.
3. Assuming the Code [Code] prompt (Public Key) is still visible on the face of the control simply push the
Advance key
to proceed to the Password [pass] prompt. If not find your way back to the Factory Page
as described above.
4. Execute the calculation defined below (7b or 8b) for either the User or Administrator.
5. Enter the result of the calculation in the upper display play by using the Up ¿ and Down ¯ arrow keys or

Formulas used by the User and the Administrator to calculate the Password follows:
Passwords equal:
7. User
a. If Rolling Password [roll] is Off, Password [pass] equals User Password [pas;u].
b. If Rolling Password [roll] is On, Password [pass] equals: ([pas;u] x code) Mod 929 + 70
8. Administrator
a. If Rolling Password [roll] is Off, Password [pass] equals User Password [pas;a].
b. If Rolling Password [roll] is On, Password [pass] equals: ([pas;a] x code) Mod 997 + 1000
Differences Between a User Without Password, User With Password and Administrator
- User without a password is restricted by the Locked Access Level [loC;l].
- A User with a password is restricted by the Read Lockout Security [rloC] never having access to the
Lock Menu [`loC].
- An Administrator is restricted according to the Read Lockout Security [rloC] however, the Ad minis-
trator has access to the Lock Menu where the Read Lockout can be changed.
