ETC00781(4) Series 100 e 02/2004
IX. Operating Conditions according to DMT Approval
(The following is a reprint of chapter 6 of the supplement I to the DMT reports
“IBS/PFG-No. 41300392 NIII” and “IBS/PFG-No. 41300292 NIII” about the performance
test of the stationary gas analyzers BINOS
®
100 (M/2M) and OXYNOS
®
100).
According to the system version and measuring results included in this report, the stationary
gas analyzers BINOS
®
100 (M/2M) from Fisher-Rosemount GmbH & Co. [now: Emerson
Process Management; the editor] are suitable for measuring the concentrations of methane
between 0 and 80 % CH
4
, of carbon dioxide between 0 and 80 % CO
2
, of carbon monoxid
between 0 - 200 ppm CO and 0 - 10 Vol.% CO and the stationary gas analyzers BINOS
®
100
(M/2M) and OXYNOS
®
100 are suitable for measuring of oxygen between 0 - 10 Vol.-%, if the
features and system version go conform with the details contained in the enclosed documents
as stated in this report, if the analysis system is operated accordingly and if the following
requirements are met:
X
When using the gas warning system, it must be ensured that the permissible variations
will not be exceeded, taking into account the systematic failures of the measuring signals
(as indicated in this report) and the local operating conditions. Consider the Code of
Pratice No. T032 of the Labor Association of the Chemical Industry "Usage of stationary
gas warning systems for explosion protection".
X
Verify that the explosion protection requirements are met when using the gas warning
system.
X
Depending on the situation, it must be verified that the preset values are low enough to
allow the system to activate the necessary protection and emergency measures and,
thus, to prevent any critical situations in a minimum period of time.
X
When at system installation, a release of one or both measuring components in the
ambient air might occur, its influence on the measuring result should be proved. A sealed
cell or an external housing purging with sample-free air of measuring gases can be used,
if required.
X
The operability of the alarms and the displays of each system should be tested with clean
air and test gas after the initial operation, after each long-time interruption, and
periodically. The tightness of gas pathes should also be tested. The tests must be
documented by keeping accounts.
