Leak Checking Sample Lines
Perform a leak check of the sample lines following installation and also whenever a line is
changed or moved. The leak check procedure involves plugging the end of the sample line and
verifying that there is no flow through the line. To perform a leak check:
1.
Put the affected Analyzer in idle mode.
2.
Go to Overview and select the Analyzer.
3.
Select Analyzer and open Flow Rate screen.
4.
Tap on the Start Flow button.
5.
Securely plug the end of the sample line being tested.
6.
Verify that the sample flow is less than 20cc, and that the Sample Pressure equals the
Supply Vacuum within a tolerance of +/-0.5 inHg.
7.
After testing all points on the selected analyzer, tap on the Stop Flow button.
NOTE
Tap on the Start Flow button on Flow Rate screen even if the pump is operating. Tapping on
Start Flow turns on the solenoid valve to provide vacuum to the analyzer.
A sample point failing to meet both the flow and vacuum conditions of step 6 indicates
either a leak in the sample line or a faulty sample inlet connection.
To troubleshoot the condition, disconnect the sample line at the inlet port at the top of the
Vertex Edge cabinet. Securely plug the inlet port and repeat the above leak check
procedure.
If the sample point passes the test with the top port plugged, the leak is somewhere in the
sample line and the line must be replaced. If the sample point fails the leak check
procedure with the top inlet port plugged, contact Honeywell Analytics for assistance.
Adjust Supply Vacuum
After all analyzers have been configured, Chemcassettes® loaded, a leak check has been
performed, and all tubes are connected, proceed to adjust supply vacuum in the Flow Rate
screen as follows.
1.
If there are any empty analyzer slots, the exhaust ports should be blocked using the plug
prior to adjusting the supply vacuum. (Plug P/N: 0235-1318)
