GAS
Status LED
The
GAS
status LED will turn red in the following situations:
o
The EC150 gas head is not connected
o
Any of the gas diagnostic flags are set
The
GAS
status LED will turn orange during the initial power up
sequence, usually 1-2 min and will turn to green when the sequence is
completed and if no diagnostic flags have been set high.
8.7.4 Diagnostic Flags
The EC100 operating system has extensive self-diagnostic capabilities.
lists 23 (numbered 0 through 22) diagnostic flags that allow the
user to identify problems associated with the operation and the performance of
the EC100 electronics and the gas analyzer. There is one master flag
(
BAD_DATA
, or flag
0
) that is set when measurements are compromised.
If any of the remaining 22 flags are set, the master flag (
BAD_DATA
) is set as
well, so that the user can filter data based on this flag only. When this flag is
set, more detailed information about the nature of the problem can be obtained
from the 22 slave flags.
When a flag is set due to improper configuration of the analyzer, inadequate
power supply voltage or grounding, extreme environmental conditions, and
unreliable or missing connections, the user should try to correct the problem by
checking the instrument setup, verifying that all components are properly
connected and configured, and that operating conditions are within operational
specifications. Other flags are associated with the proper function of the
internal components of the analyzer. If any of these flags are set, consult with
Campbell Scientific for assistance in diagnosing the problem and, if necessary,
arrange to send the instrument for repair.
If connected to a datalogger, the EC100 could be automatically
configured under
CRBasic
program control. The user should
verify the proper configuration in the datalogger program.
