DIAGNOSING PROBLEMS
DIAGNOSTIC MENUS
The Diagnostic Menu for the MC³ Controller is provided to allow access to additional displays and
values. It is not necessary to access this menu under normal operating conditions. It is provided as
a troubleshooting tool and should be accessed only by knowledgeable personnel. The Diagnostic
Menu has its own password.
Access to the Register editor is only allowed if the logic input “Register Access” is ON. See List of
Logical Inputs on page 37. If the logical input is OFF, the button for the Register Editor will not
appear on the diagnostic screen.
CAUTION: The values in this menu are very sensitive. Changing any of these values could adversely affect the
operation of the Feeder Controller.
