The most common and/or serious instrument failures will result in a warning message being displayed on 
the front panel.  Table 11-1 lists warning messages, along with their meaning and recommended 
corrective action.   

It should be noted that if more than two or three warning messages occur at the same time, it is often an 
indication that some fundamental analyzer sub-system (power supply, relay board, motherboard) has 
failed rather than indication of the specific failures referenced by the warnings.  In this case, it is 
recommended that proper operation of power supplies (See Section 10.5.2), the relay board (See Section 
10.5.6), and the A/D Board (See Section11.4.7.1) be confirmed before addressing the specific warning 
messages. 

The analyzer will alert the user that a Warning message is active by flashing the FAULT LED and 
displaying the Warning message in the Param field along with the CLR button (press to clear Warning 
message). The MSG button displays if there is more than one warning in queue or if you are in the TEST 
menu and have not yet cleared the message. The following display/touchscreen examples provide an 
illustration of each: 

 

The analyzer will also alert the user via the Serial I/O COM port(s) and cause the FAULT LED on the front 
panel to blink.
