2-7 Passwords and Security
The controller provides four levels of security. Depending on the security level, some or all of
the setup menus may be locked. The security level must be changed in order to unlock these
menus. The current security level is displayed in the lower right corner of the menu display.
The default security level is 3.
Security levels are changed by changing the password value using the Up and Down buttons
and pressing the Enter button. Values in the setup menus can be changed only when the
correct security level is set. Note that the security level value itself can be changed in any
security level.
Use the following procedure to change the security level:
1. Press the Index button three times to access the Secure menu.
2. Press the Enter button. The LCD screen will display the current security level.
3. Use the Up or Down buttons to change the value in the display line to the password
of the new desired security level.
4. Press the Enter button to select this new security level and retain the value in
EEPROM. The display will change from the password value to the selected security
level for that password.
