Teledyne M300EM Fault Diagnosis With Warning Messages, Sample, Bench Temp Warning, Co =, Test Cal

Troubleshooting & Repair Teledyne API – Technical Manual - Model 300E Family CO Analyzers

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 13-1lists 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:

SAMPLE	BENCH TEMP WARNING	CO = XXX.0
TEST CAL	MSG	CLR SETUP

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.
