11.4 Using the Write-Protect Password to Ensure
Program Security
Parameter values can be password-protected using the LCD OIM.
When the password is enabled, parameter values can be displayed.
However, if there is an attempt to change a parameter value, a
password pop-up box will appear on the OIM screen to prompt for
the user-defined password.
To set the write-protect password, select the Password icon from the
main menu. See figure 11.6. The password value can range from 1
to 9999. A value of 0 disables the password (factory default).
When the password is enabled, the lock symbol on the screen
changes from to .
When you enter the password, you can adjust parameters until you
select Logout or return to the process display screen, which
re-activates the password. Refer to section 9.8 in chapter 9 for
information about the process display screen.
This option is not supported in the VS Utilities software.

ATTENTION: It is the user’s responsibility to determine how
to distribute the write-protect password. Reliance Electric is
