Teledyne M300EM User Manual

13.1.1.   FAULT DIAGNOSIS WITH WARNING MESSAGES 

The most common and/or serious instrument failures will result in a warning message being displayed on the 
front panel.  Table 13-1 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 13.5.2), the relay board (See Section 13.5.5), and the A/D 
Functions (see Section Error! Reference source not found.) be confirmed before addressing the specific 
warning messages. 

The analyzer will alert the user that a Warning Message is active by displaying the keypad label MSG on the 
Front Panel.  In this case the Front panel display will look something like the following: 

 

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.
