1.3 Principle of operation
The detection and measurement of carbon monoxide in the Model 300 is based on the
absorption of Infra Red (IR) radiation by CO molecules at wave lengths near 4.7 microns.
In practice, the Model 300 uses a high energy heated element to generate broad-band IR
light. This light is passed through a rotating Gas Filter Wheel which causes the beam to
alternately pass through a gas cell filled with Nitrogen, (the Measure Cell) and a cell
filled with CO/Nitrogen Mixture (the Reference Cell). This alternation occurs at a rate of
30 cycles/second and causes the beam to be modulated into Reference and Measure
pulses. During a Reference pulse, the CO in the gas filter wheel effectively strips the
beam of all IR energy at wave lengths where CO can absorb. This results in a beam
which is unaffected by any CO in the Sample Cell. During the Measure pulse, the
Nitrogen in the filter wheel does not effect the beam which can subsequently be
alternated by any CO in the sample cell. The Gas Filter wheel also incorporates an
optical chopping mark which superimposes a 360 Cycles/Second Light/Dark modulation
on the IR Beam. This high frequency modulation is included to maximize detector
signal-to-noise performance.
After the gas filter wheel the IR beam enters the multi-pass sample cell. This sample cell
uses folding optics to generate a 16 meter absorption path length in order to achieve
maximum sensitivity.
Upon exiting the sample cell, the beam passes through a band-pass interference filter to
limit the light to wave length of interest.
Finally, the beam strikes the detector which is a thermoelectricly cooled solid-state
photo-conductor.
This detector, along with its pre-amplifier and bias voltage supply convert the light signal
into a modulated voltage signal.
The detector output is electronically demodulated to generate two DC voltages, CO
MEAS and CO REF. These voltages are proportional to the light intensity striking the
detector during the Measure Pulse and Reference Pulse, respectively.

1.5 Installation and overview
The Model 300 is shipped with the following standard equipment:
1. Power cord.
2. Instruction manual.
CAUTION
To avoid personal injury, always use two persons to lift and
carry the Model 300.
Upon receiving the Model 300 please do the following:
1. Verify no apparent shipping damage. (If damage has occurred please
advise shipper first, then Teledyne API.)
2. When installing the Model 300, allow a minimum of 4 inches (100mm) of
clearance at the back of the instrument and 1 inch (25mm) of clearance on
each side for proper ventilation. Also, be sure that the clearance below the
chassis is unobstructed by at least the height of the instrument feet.
3. Connect sample inlet line to the sample port on rear panel.
NOTE
SEE FIGURE 1.4 FOR REAR PANEL PNEUMATIC
CONNECTIONS. SAMPLE GAS SHOULD ONLY COME
INTO CONTACT WITH PTFE, GLASS OR STAINLESS
STEEL. LEAK CHECK ALL FITTINGS WITH SOAP
SOLUTION.
MAXIMUM PRESSURE FOR LEAK CHECK IS 5 PSI.
CAUTION
Connect the exhaust fitting on the rear panel (See Fig. 1.4) to a
suitable vent outside the analyzer area.
4. Connect IZS inlet input (if installed) to a clean, dry air supply.
5. Connect a recording device to the terminal strip connections on the rear
panel (See Figure 1.2).
6. Connect the power cord to an appropriate power outlet (see the serial
number tag for correct voltage and frequency).
P/N 02163G1 Teledyne API Model 300 CO Analyzer Instruction Manual - Page 5
CAUTION
CHECK THAT ANALYZER IS SET UP FOR PROPER
VOLTAGE AND FREQUENCY.
CAUTION
POWER PLUG MUST HAVE GROUND LUG.
7. Turn on the M300 by switching the switch on the lower right corner of the
front panel (See Figure 2.1). The front panel display should light with a
sequence of messages, -API - M300 - software version number, then a
normal display as shown in Figure 2.2.
8. Allow about 60 minutes for the temperatures to come up to their
respective setpoints then press the left most button on the front keyboard
to scroll through the TEST values. Compare these values to those noted
during the final factory checkout listed in Table 1.1. The values observed
should closely match the Table 1.1 values.
9. Select the range on which the analyzer will be calibrated.
a. From the SAMPLE menu press SETUP to enter the SETUP menu.
(See Figure 2.2 for appearance of front panel.)
b. Enter the PASSWORD (818).
c. Press RNGE (RANGE).
d. Press SET.
e. Enter the derived full scale range for analog outputs and press ENTR.
f. Press EXIT 2 times to return to the SAMPLE menu.
10. Adjust the analyzer zero point.
a. Input zero air into the sample port.
b. Press CAL from the SAMPLE menu and enter the password (818).
c. Press ZERO.
d. It usually takes about 5 to 10 minutes for the reading to stabilize
near zero. After a stable reading has been obtained press ENTR.
The display should now read 0.0 ppm carbon monoxide.
P/N 02163G1 Teledyne API Model 300 CO Analyzer Instruction Manual - Page 6
NOTE
REPEATEDLY PRESSING ENTR TO GET THE
INSTRUMENT TO DISPLAY THE CORRECT SPAN/ZERO
VALVE DOES NOT IMPROVE THE ACCURACY OF THE
CALIBRATION, NOR DOES IT SPEED UP
STABILIZATION. THE REASON FOR WAITING 5-10
MIN. IS THAT IT TAKES THE INSTRUMENT A PERIOD
OF TIME TO ESTABLISH AN ACCURATE AVERAGE
FOR THE SPAN/ZERO READING.
11. Adjust the Analyzer span point.
a. Input span gas of approximately 80% of the related full scale range
concentration from a known source through the sample port of the
Analyzer.
b. Go to manual calibration by pressing the CAL button while in the
sample mode.
c. Enter the operator password (512).
d. The menu should now show SPAN, CONC, and EXIT. Enter the
concentration of the CO calibration gas by pressing CONC and
entering the value from the keyboard.
e. Wait 10 minutes for a stable reading to be attained and then press
SPAN, followed by ENTR. If the SPAN button is not displayed, this
means that the Analyzer is too far out of adjustment to do a reliable
calibration and thus it is not permitted (see Section 3.1 for information
on the calibration limits). The operator can exit the manual calibration
procedure only by pressing the EXIT button.

1.6.4 RS-232
The RS-232 connection is a male, 9-pin D-sub connector at the location shown in Figure
1.2.
1.6.5 Pneumatic system
The Model 300 is equipped with a vacuum pump capable of pulling 800 cc/min across a
critical flow orifice. This allows a smooth, stable flow of sample through the Analyzer.
Sample enters the Analyzer through a 5 micron TFE particulate filter element (37 mm
diameter) mounted immediately behind the front panel. The sample then enters directly
into the sample cell. Please see Figure 1.3 for a flow diagram and Figure 1.4 for
pneumatic connections.
P/N 02163G1 Teledyne API Model 300 CO Analyzer Instruction Manual - Page 11
A critical flow orifice is used to control the sample flow. The orifice is a precision drilled sapphire jewel protected by a 20 micron sintered filter. The critical flow orifice
never needs adjustment and maintains precise flow control as long as the ratio of the up stream to down-stream pressures is greater than .53 (sonic flow conditions).
1.6.6 Sample gas connection (see Figure 1.4)
A 2 m section of 1/4" O.D. PTFE tubing is needed to connect the sample source to the
Analyzer.
NOTE
USE PTFE, GLASS, STAINLESS STEEL OR
NON-REACTIVE MATERIALS FOR SAMPLE GAS
CONNECTIONS.
NOTE
USE VENT LINE WHEN SAMPLING FROM
PRESSURIZED MANIFOLDS - SAMPLE PRESSURE
SHOULD NOT EXCEED ±1" H2O
1.6.7 Zero/span valve connections (see Figure 1.4)
Zero air and span gas manifolds should supply their respective gases in excess of
800cc/min demand of the Analyzer. The manifold should be vented to the outside
atmosphere and be of sufficient length and diameter to prevent back diffusion and
pressure effects.
Adequate zero air can be supplied by the M300 using the IZS option or by using a
commercial calibrator.
P/N 02163G1 Teledyne API Model 300 CO Analyzer Instruction Manual - Page 12
1.6.8 Exhaust connections (see Figure 1.4)
A single 1/4" O.D. tube should be connected from the Analyzer sample exhaust to an
area outside of the room the Analyzer occupies. The maximum length of the exhaust line
should not exceed 30 feet.
CAUTION
Connect the exhaust fitting on the rear panel (See Fig. 1.4) to a
suitable vent outside the analyzer area.

1.7 Operation verification
The Model 300 Analyzer is now ready for operation.
1. Read Sections 1.3 and all of Section 4 of the manual to understand the
Analyzer operation.
2. Turn on the power by pressing the on/off switch on the front panel (see
Figure 2.1). The display should turn on and green (sample) status LED
should be energized. The green LED should blink indicating the
instrument has entered the HOLD-OFF mode. Sample mode can be
entered immediately by pressing the EXIT button on the front panel. The
red "fault" light will also be on until the flows, temperatures and voltages
are within operating limits. Clear the fault messages.
3. After a 60 minute warm-up, review the TEST function values in the front
panel display by pushing the left most keyboard button labeled TEST.
Not every TEST function is a diagnostic of correct analyzer operation,
therefore TEST functions not covered below can be ignored for now.
4. CO REF, CO MEAS - TEST function values should be between 3200 mV
and 4700 mV.
5. Pressure - 29 to 30 Inches-Mercury-Absolute at sea level. Other values
will be displayed depending on altitude of Analyzer.
6. Sample Flow - 800 cc/min ±10 %
7. Sample Temp - Ambient temperature ± 10 °C
8. Optical Bench Temp - 48°C ±1° The computer drives the temp to this
setpoint.
9. Filter Wheel Temp - 68°C ±2° The computer drives the temp to this
setpoint.
10. Box Temp - Ambient ±10 °C
11. DC Power Supply - 2500 mV ± 50 mV - This is a composite of all of the
DC voltages in the instrument. The value is not important but it should be
within the range indicated.
12. If the TEST functions are within the limits given above, chances are very
good the instrument will function correctly. If there is a problem, please
read the manual and check your set-up. The Model 300 is now ready for
calibration (see Section 3.5).

IN INTERNAL OVERHEATING.
1.8.2 Zero/span valves
The Zero/Span Valve option consists of three stainless steel solenoid valves mounted
inside the Analyzer connected to admit sample gas or customer-generated zero air or span
gas.
The valves are controlled from the front panel push-buttons, the auto-timer via the
RS-232 interface, or by remote contact closure.
A Zero air manifold should supply gas in excess of the 800 cc/min +
Analyzer. The zero manifold should be connected at the IZS/Zero Air fitting on the rear
of the Analyze and should be vented to the outside atmosphere.
A Span gas manifold can be connected to the analyzer in either of two ways.
1. If it is desired to use span gas directly from a pressurized source (e.g. a gas
cylinder) the connection can be made directly to the Pressure Span port on
the analyzer rear panel. In this case the Vent/Span port at the rear panel
should be vented to a suitable exhaust manifold at ambient atmosphere
pressure. The pressure regulator on the gas source (cylinder should be
sent to provide 30-35 PSI delivery pressure.
2. If it is desired to use span gas from a source which delivers gas at
atmosphere pressure (e.g. a calibrator), the span gas manifold should be
connected at the Vent/Span port at the Analyzer's rear panel, and the
Pressure/Span port should be capped.

1.8.3 Internal zero/span
The IZS option includes the valves and connection parts described above, and in addition,
includes an internal zero air scrubber. This scrubber operates by catalyticly converting
CO in the gas stream to CO
connections should be made as described above and a source of clean air at ambient
pressure should be connected to the IZS/Zero Air Port on the Analyzer's rear panel.

2.0 OPERATION
2.1 Key features
The important features of the Teledyne API Model 300 CO Analyzer are listed below.
2.1.1 CO readout
The Teledyne API Model 300 CO Analyzer constantly displays the current Carbon
Monoxide reading (in PPM) in the upper right hand corner of the alphanumeric display.
2.1.2 CO analog output
The Teledyne API CO Analyzer provides a buffered analog output of the current CO
readings on each of two pairs of outputs on the rear panel (see Figure 1.2) for DAS and
recorder reporting. The analog outputs provide for 20% overrange. For example, on the
50 ppm range the M300 will correctly report concentrations up to 60 ppm and output up
to 6.00 volts to the DAS and recorder outputs.
In addition TEST function values can be routed to a third analog output.
2.1.3 E2 ROM backup of software configuration
The Teledyne API CO Analyzer has a few jumpers that need to be set by the operator.
Configuration of the Analyzer is done under software control and the configuration
options are stored in electrically erasable (E2) ROM. Thus, configuration options are
saved even when the Analyzer is powered off.
There is one exception to this. The analog output voltage ranges are set by jumpers on
the A/D-I/O board as shown in Section 10.6.3.
2.1.4 Adaptive filter
The Teledyne API CO Analyzer is able to provide a smooth, stable output by means of an
adaptive filter. During conditions of constant or nearly constant concentration the filter is
allowed to grow to 600 samples (2 minutes) in length, providing a smooth, stable
reading. If a rapid change in concentration is detected, the filter is cut to 50 samples to
allow the Analyzer to quickly respond to rapidly varying signals.
2.1.5 Data acquisition
The Teledyne API CO Analyzer contains a built-in data acquisition system which keeps
track of the average CO readings and the last 100 averages. This data is made available
to other systems via the RS-232 interface. The Analyzer can be programmed to
automatically output a 1 minute to 60 minute average. The last 100 averages can be
called up through the remote RS-232 I/O or viewed on the display through keyboard
call-up.

2.1.6 RS-232 interface
The Teledyne API CO Analyzer features an RS-232 interface which can output the
instantaneous and/or average CO data to another computer. It can also be used as a
command and status channel to allow another computer to control the Analyzer. Refer to
Figure 1.3 for details on using the RS-232 interface. Tips on connecting the RS-232 port
can be found in Appendix B.
2.1.7 Password protection
The Teledyne API CO Analyzer provides password protection of the calibration and
setup functions to prevent incorrect adjustments to the Analyzer. There are three levels
of passwords which correspond to operator, supervisor/maintenance, and analyzer
configuration functions. When prompted for a password, any of the valid passwords can
be entered, but the CPU will limit access to the functions allowed for that password level.
Each level allows access to the functions of all the levels below plus some additional
functions. Table 2.1 lists the password levels and the functions allowed for each level.
