3. Turning On & Fuel Selection
3.1 Turning On
Always: - Before turning on please ensure
that the
In-Line Pump Protection Filter
(shown across) is connected to the Gas
Sample Port (see 2.2 or 2.4).
**THIS MUST REMAIN ON THE UNIT
AT ALL TIMES.**
Failure to do so may result in pump failure
and will invalidate the warranty.
Press the Power Key for approximately 2 seconds and the TPI 712 will start
up and display ALL Segments on the display for approx. 1 second. The 712 will
then enter its 30-second purge period countdown with the following screen being
displayed.
The instrument should ALWAYS be turned on
in a clean air environment as the 30 second
purge will attempt to set the Carbon Monoxide
level to 0 ppm and the Oxygen to 20.9%.
If there is insufficient clean air in the sensor
chamber after the 30 second purge period an
error indicating this may
be displayed, please
see troubleshooting guide (appendix D) for
appropriate remedy. If the error is still present
after attempting the suggested remedy please
call the
TPI HELPLINE
01293 530196
3.2 Fuel Selection
During the last 20 seconds of the 30 second purge time (i.e. as the 712 counts
down from 19 to 0) the user can scroll through the following Fuels: - Natural Gas,
LPG, Light Oil, Heavy Oil & OPT 1-6 (1=Bituminous Coal, 2=Anthracite Coal,
3=Coke, 4=Butane, 5=Wood(Dry) & 6=Bagasse) by repeatedly pressing the
Up Arrow Key to select the Fuel they are working with.
4. THE 5 FUNCTIONS
After the 30-second countdown the instrument is ready to take Flue Gas,
Temperature, Pressure or Leak Detection readings and will Display the
following Screen.
You are now ready to take Flue Gas Analysis
Readings. Please continue on with the manual from
Section 4.1 (below) which will guide you through the
various Analysis Screens.
However, if you do not wish to perform a Flue Test at
this moment Press the Func/Backlight Key
and move onto Section 4.2 of the manual.
At any time you can activate the Backlight by holding down
the
Func/Backlight Key for 2 seconds.
4.1 Function 1: - Flue Gas Analysis
Ensure you have connected the Temperature Sampling Probe complete with
In-Line Water Trap Bowl Filter to the In-Line Pump Protection Filter (See 3.1)
which should ALWAYS be connected to the Gas Sample Port (see 2.2 or 2.4)
and that the ‘K’ Type Thermocouple Plug is in Thermocouple Socket (ch1)
(see 2.4). Also ensure that a ‘K’ Type Air Probe is connected to
Thermocouple Socket (ch2) (see 2.4) in order to calculate efficiency.
Your temperature-sampling probe comes complete with an In-Line Water Trap
Bowl Filter as standard.
This consists of a Particle Filter in the
Bowl Compartment and a Disc Filter
in the Lid (as shown in the diagram
across). The Disc Filter in Lid will
prevent any excessive water from
entering the 712 Flue Gas Analyser if
used correctly.
If you are working with OIL then you MUST
ensure that you also use the optional
Oil Filter as shown below. Failure to do so will result in erroneous readings.
If any of the filters
become excessively dirty or blocked then the
following screen will be displayed as a warning and no further
readings will be able to be taken until either the dirty filters are
replaced or the blockage removed:-
The 712 will also give off an audible Beeping Alarm
to warn that a “FLo Err” is being detected
