Appendix 3: Parameter Lock / User Password Instructions
Provides users with the ability to prevent unauthorized operators from making
changes to the programmed functions. If you do not need to take advantage
of this feature, do not enter anything into this function. The factory default
is disabled, and no Password is necessary to make changes to the program.
When any value other than 0 is entered into this Function, the Parameter Lock
is enabled and that number becomes the User Password. From that point
forward, it will be necessary to enter the User Password in this Function prior
to making changes in any programmed function, including this one. When the
Parameter Lock has been enabled, attempts to alter the program will result in
the display reading Err whenever the READ / ENTER key is pressed.
To be able to alter the program after the Parameter Lock has been enabled, go
to Function (F060) and enter the correct user Password. When the READ /
ENTER button is pressed, the display will read PASS, indicating that the User
Password is correct and the system is unlocked. You will have 5 minutes in
which to make a change in the program. This 5 minute window resets whenever
any key is pressed, so it floats to give you 5 minutes after the last entry. After
5 minutes of no keypad activity, the Parameter Lock is reinstated with the
current user Password. Subsequent changes will require re-entering the User
Password.
To change the User Password or to disable the Parameter Lock function,
enter the programmed User Password first, then set Function F060 to 0 (F060
= 0), disabling the Parameter Lock. If you do not re-enter the Password or
enter a new user password, the Parameter Lock feature will remain disabled.
If you enter a different number into this Function, the new number becomes
your new User Password.
The User Password will not be displayed after being entered or at any other
time. The number displayed after the READ / ENTER key is initially pressed
is for reference only.
Caution: DO NOT LOSE YOUR PASSWORD
. If the password has
been lost or forgotten, contact TOSHIBA for assistance in retrieving it with
authorization.
