4.1.3 Flow Status (Sample and Bypass)
The Flow Status screen shows specifically where a flow problem exists on both the sample and
bypass manifolds.
Figure 7: Sample Manifold Flow Status Figure 8: Sample Manifold Flow Status (Dual)
The Flow Status screen consists of the following:
"Sample Manifold Flow Status" - This is the screen title and it indicates which flow status is
currently being displayed. The title may also appear as "Bypass Manifold Flow Status" and changes
alternately with the "GOTO BYPASS" button described below..
"Point 1 Flow Normal" through "Point 32 Flow Normal" – During normal operation the array of 32
indicators are green and display “Point [XX] Flow Normal” for whichever manifold is selected.
When flow failures exist the indicator(s) will turn red and display "Point [XX] Flow FAILURE"
depending on which point and which manifold is in flow fail. [XX] will display which point
number, 1-32 is normal or in failure.
NOTE: Bypassing a point (eliminating a point from the sampling sequence) that has a sample or
bypass flow loss indication, will lead to a situation where the trouble condition cannot be cleared.
The MultiGard 5000 unit must access the line in question to determine that the fault condition has
been corrected whereby the CONDITION ACKNOWLEDGEbutton may be used to return the unit to
the normal operating state.
"Flow Loss on Sample!" – This indicator will show when viewing the “Bypass Manifold Flow
Status” screen and a flow failure has occurred in the sample manifold. When the screen is switched
to view the “Sample Manifold Flow Status” screen, this indicator turns off.
"Flow Loss On Bypass!" - This indicator will show when viewing the “Sample Manifold Flow
Status” screen and a flow failure has occurred in the bypass manifold. When the screen is switched
to view the “Bypass Manifold Flow Status” screen, this indicator turns off.
"GOTO Bypass" - This is a push button that changes the screen from displaying sample status to
bypass status. After being pushed the button now indicates "GOTO SAMPLE". Note that the screen
