The User password allows you to access the System Setup screens from the System Status screens (Figure 6).
When the User password is set to the factory-default value of 0000, password-protected access is disabled, and a
password is not required to access the System Setup screens and change control system parameters and values.
Changing the User password to a value other than 0000 enables password-protected access.
The Admin password allows you access to the System Setup screens just like the User password. The Admin
password also provides access to the User Password Setup screens (Table 12) and the Administrator Password
Setup screens (Table 13), and change the password values. The factory-default Admin password is 1234.
The User and Admin Password Setup screens behave differently than the other System Setup screens. In the
System Setup screens, the entire parameter value blinks and you enter an entire new value, then press to save
the entire value and go to the next screen.
In the User and Admin Password Setup screens, you must enter each digit in a screen individually and press to
save the single-digit value and go to the next digit in the four-digit password string.
When you press to save the last digit in the Change User Password or Change Admin Password screens, the
password is saved and the UI displays the next screen. When you press to save the last digit in the Confirm
Admin Password screen, the password is confirmed and the UI displays the Validate Admin Password Change
screen.
Notes:
• After you have selected and saved a digit, you cannot go back and change the digit. You must navigate to
the change password screen and re-enter the entire four-digit password with the correct digits.
• If you change the Admin password, be sure to record and store the password. If you do not recall the
Admin password in the future, you cannot access the System Password Setup screens. If you do not recall
the User password (after it is changed from the default 0000), you cannot access the System Setup
screens.
Table 12 provides procedures for and information on changing the System 450 User password.
