Maintenance | 4-5

2. If the analyzer uses

measured

Pressure Compensation (optional),

change the pressure compensation to

fixed mode

so that a “

f: Sample

gas pressure too low

” alarm does not occur. To do this, view the

Cell/

Misc Parameters

dialog box and enter a value in the

Default Cell

Pres

(pressure compensation) field that is the same as, or approxi-

mately, the Measuring Cell pressure. Refer to “Cell/Miscellaneous
(Compensation) Parameters” in Chapter 4.

Close the isolation valve on the Sample Probe. Backpurge the analyzer
sample system with Zero gas for 2–3 minutes.

3. Change the

Flow Control

setting to ‘

1

’ (

shut-in/off

). Click

Apply

(next

to

Flow Control

) and then click

OK

.

Bleed down the sample system to atmospheric pressure (check gauge).
Close the valve on the Vent Line side.

4. Disconnect AC power to the analyzer and power down the computer

before performing maintenance on the analyzer.

Hazardous Locations

Always disconnect mains AC power and/or alternate power sources
to the analyzer before opening any covers or doors on the analyzer to
check or perform maintenance on any components within the enclo-
sures.

If it is necessary to open the analyzer’s covers or doors while the
circuits are live, test the area for flammable gases (and proceed only
when the area is safe). To work on the analyzer with it powered up
and its electronics enclosure(s) open, take appropriate precautions to
avoid electrical shock. Hazardous voltages are present inside.

!

WARNING



See Fuse Legend

inside analyzer’s Lower

Enclosure.
