7.10.4 Cabinet Reset

The main control board has two software operating resets available for qualified service personnel.

The two types are the following:

Factory Reset - Resets setpoints and selected option settings. Factory reset should be used in the event the

system memory develops an error in operation. Cabinet type, motor type and calibration data

will not be affected with this reset.

Master Reset - Resets all calibration, cabinet type, motor type, sensor data, and options settings back to

default settings. Master Reset should only need to be used for a main control board

replacement.

After pressing the Calibration/Service menu item, a password screen will appear. The default password is “9876”.

Once the service password is entered, the Calibration/Service menu will appear.

Select CABINET RESET from the menu.
