Chapter 7 

Diagnostic  Mode 

Unlike the Auto Mode, which uses a recipe to operate all of the machine’s

 components 

simultaneously, the diagnostic mode is used for troubleshooting purposes only and starts 
each component individually. In order to set the machine to the Diagnostic Mode, the 
user must be logged in as a Supervisor.

 

In diagnostic mode the control panel screen 

will look like Figure 7.1. 

          

 

 

Figure 7.1: 

Control Panel in Diagnostic Mode 

 

There are three additional tools that appear on the screen for diagnostic mode. 

 

• 

start buttons for the fans and deck eccentric 

• 

feedback for the deck end raise position 

graphs for the amperage, voltage, and temperature of the drives and readout of the 
drive frequencies for the fans and deck eccentric
