4. Basic Analyzer Controls
4.1 Turning The Analyzer On
Always:
- Before turning on please ensure that the Mini Pump Protection Filter
assembly and the Temperature Sampling Probe complete with In-Line Filter or the
Tubing & In-Line Filter for Leak Detection are
not
connected to the Gas Sample
Port (see 2.2 or 2.4)
Press and hold down the Power Key and the TPI 709R will start its 30 second
countdown 'PURGE' will be displayed: - The instrument MUST be turned on in a
clean air environment as the 30 second purge will set the Carbon Monoxide level
to Zero and the Oxygen to 20.9%.
Ensure that the filters are clean and dry as dirty or wet filters will result in a loss
of flow rate and 'Lo Flo' will be displayed to inform you that filters should be
changed
During the last 20 seconds of the 30 second purge time the user can scroll
through the following Fuels: - Natural Gas, LPG, Light Oil, Heavy Oil, OPT1 :
Bituminous Coal, OPT 2 : Anthracite Coal, OPT 3: Coke, OPT 4: Butane, OPT 5:
Wood (Dry), OPT 6: Bagasse by pressing the Up Arrow Key to select the Fuel
they are working with. When desired fuel is displayed release the key, displayed
fuel is now selected.
After the 30 second countdown the instrument is ready to take Flue, Temperature,
Pressure or Leak Detection readings and Combustion Display 1 will be the first
display.
The 709R will auto power off if no keys have been pressed for 10 minutes and the
CO level is below 15ppm. This feature can be disabled see Appendix F.
The Scroll/Enter Key allows you to scroll through the combustion displays as out-
lined in section 5.3. The Func Key is used to select the 709R function mode and
allows you to set it to be a combustion analyzer, manometer, thermometer, or
combustible leak detector. In addition, the Func Key is used to access the date
and time display. See section 6 for more information on the Func Key.
NOTE: When selecting oil as fuel be sure to use the optional
oil filter (A773) or readings could become erratic. See
Appendix E for installation instructions.
Appendix E: ERROR CODES & TROUBLESHOOTING
The 709R analyzer will display certain codes to let you know of a malfunction.
Code

Code Definition
Possible Causes
Corrective Action
Flo
Err
Pump not drawing sample at
correct flow rate.
Blockage / kink in flue probe
hose.
Dirty or blocked filter(s).
Worn pump.
Check and rectify.
Replace filter(s).
Return to TPI for service.
InIt
O2
Err
Oxygen sensor failed to ini-
tialize
Flue probe connected to
709R prior to power up.
709R did not purge com-
pletely from last sample.
Worn or defective oxygen
sensor.
Disconnect probe and
restart.
Purge for 20 minutes and
restart.
Return to TPI for sensor
replacement or install new
sensor.*
Try manually initializing the
sensor. See Appendix G.
InIt
CO
Err
Carbon monoxide sensor
failed to initialize.
Flue probe connected to
709R prior to power up.
709R did not purge com-
pletely from last sample.
Worn or defective carbon
monoxide sensor.
Disconnect probe and
restart.
Purge for 20 minutes and
restart.
Return to TPI for sensor
replacement or install new
sensor.*
Try manually initializing the
sensor. See Appendix G.
Lo
bat
Low battery.
Battery needs to be charged. Charge battery. If the battery
won’t hold a charge, replace
the battery.
oFL
Overflow indication. The car-
bon monoxide being mea-
sured is above the instru-
ments capability.
CO being measured is too
high or low.
Remove the CO source and
allow the 709R to purge.
oFL
Overflow indication. The tem-
perature being measured is
outside the maximum mea-
surement capability.
Temperature being measured
is too high or low.
Remove pressure source.
oPEn
Unable to read thermocouple
(temperature).
Temperature probe not con-
nected to input.
Worn temperature sensor.
Connect temperature probe
to analyzer.
Replace temperature probe
or flue probe.
*Sensor replacement requires calibration gas.
