Note:

Using Method 1 Lockout all settings can be modi-

fied by anyone who knows how to find their way to

the [SLoC] and [rloC] parameters

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 2 (Password Enable)

It is sometimes desirable to apply a higher level of

security to the RUI where a password would be re-

quired to access the menus. If Password Enabled
[pas;e]

in the RUI Page under the [`loC] Menu is

set to on, an overriding Password Security will be in

effect for the RUI. Without the appropriate password

(User or Administrator), specified menus within the

RUI will remain inaccessible based on the Locked Ac-

cess Level [loC;L] prompt. On the other hand, a User

with a password would have visibility restricted by

the Read Lockout [rloC]and the Set Lockout [sloC]

settings. As an example, with the following settings:
- Password [pas;e] Enabled
- Locked Access Level [loC;L] set to 1
- Read [rloC] and Set [sloC] Lock set to 5
a User (having entered a User password) would

have access to all menus with the exception of the

Lock menu. Therefore, Read and Set Lock cannot be

changed. If an Administrator enters the appropriate

password all menus would then become available

again.
How to Enable Password Security
Follow the steps below:
1. Go to the RUI Page by holding down the Advance

key and the Down ¯ key for approximately six

seconds

2. Push the Down ¯ or Up ¿ key to get to the [`loC]

menu. Again push the Advance

key until the

Password Enabled [pas;e] prompt is visible

3. Push either the Down ¯ or Up ¿ key to turn it on.

Once on, 4 new prompts will appear:
a. [loC;l], Locked Access Level (1 to 5) correspond-

ing to the lockout table above.

b. [roll], Rolling Password will change the Cus-

tomer Code every time power is cycled.

c. [pas;u], User Password which is needed for a

User to acquire access to the control.

d. [pas;a], Administrator Password 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 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

higher 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 Menus, go to the

RUI 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 origi-

nally setup the control.

1. Acquire either the User Password [pas;u] or the

Administrator Password [pas;a].

2. Push the Advance

key until the Code [Code]

prompt appears.

Note:

a. If the the Rolling Password is off push the Ad-

vance

key until the Password [pass] prompt

is 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

seconds 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

RUI 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 dis-

play by using the Up ¿ and Down ¯ arrow keys or

use EZ-ZONE Confgurator Software.

6. Exit the RUI Page by pushing and holding the In-

finity ˆ key for two seconds.

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
