6.6 Error Detection
Specific errors can be detected in one of the following ways:
1 Observing the blink pattern on the Warning LED, refer to Table 6-7 on page
6-7 for a complete list of error or warning indicated.
2 On the optional LCD Display. When an error occurs, an error code will
replace the concentration output. If there is a warning (less serious
problem) the "Warning" annunciator will be displayed; by pressing key 5 a
warning code will be displayed. For example, if there is no gas in the
transducer the display will show "ER 80", because no measurable signal
was found. A complete listing of errors/warnings is given in
Table 6-7 on
page 6-7 .
3 Via RS-232C; read the error log.
4 Via the Monitor Software pop up window.
6.6.1 LED Blink Patterns
Refer to Table 6-7 on page 6-7 .
6.6.2 Error Codes
On the LCD and in the error log, errors are uniquely coded in hexadecimal with
each bit representing a different error. This way, multiple errors can be
recorded. Refer to
Table 6-7 on page 6-7 for error codes. Multiple errors are
decoded as follows:
Example 1:
There are two errors present.
The displayed error is 0x0084
It is caused by:
Ambiguous Gas Warning 0x0004
No Signal Error 0x0080
Error Code summed 0x0084
Example 2:
There are three errors present.
The displayed error is 0x001C
It is caused by:
Identical Gasses 0x0010
Bad Peak Shape 0x0008
Ambiguous Gasses 0x0004
Error code summed 0x001C
