11.1 Error listing of the
gas-lab Q1
The following list describes all error messages that may appear on the error
listing of the gas quality measurement. Furthermore, the performance of the
device when gas quality-relevant errors occur is explained.
The error classification follows the
DVGW-Arbeitsblatt G485
(DVGW Code of
Practice G485) and thus complies with the DSfG Specification. The letter in front
of the error number classifies the priority level of the error:
A
stands for alarm,
H
for hint, and
W
for warning.
The following list describes all error messages that may appear on the error
listing of the gas quality measurement.
A040 Rhon failure / A060 Hon failure / A070 CO2 failure
If one of the alarms A040, A060 or A070 is generated, the respective physical final value
can not be calculated due to inconsistency of the supplied raw values. Possible causes
are:
-Timeout expired for GQ source data telegram and no replacement available
measurement;
-data source availablemarked as disturbed and no replacement measurement,
-by incorrect GQ data source settin in parametration..
A041 Rhon min alarm / A042 Rhon max alarm
The lower and upper alarm limits for the target value Rho is defined in the
parameterisation of the
gas-net
Q1. If one of the calculated final values violates an alarm
limit, the associated alarm will be generated.
A061 Hs min alarm / A062 Hs max alarm
The lower and upper alarm limits for the target value Hs is defined in the parameterisation
of the
gas-net
Q1. If one of the calculated final values violates an alarm limit, the
associated alarm will be generated.
A071 CO2 min alarm / A072 CO2 max alarm
The lower and upper alarm limits for the target value CO
2
is defined in the
parameterisation of the
gas-net
Q1. If one of the calculated final values violates an alarm
limit, the associated alarm will be generated.
