3. DESCRIPTION OF OPERATING PARTS AND CHECK ITEMS
3.1 Sampling system
3.1.1 Outline
The sampling system is used to supply a specified amount of automotive emissions to the measuring unit, by removing a trace of dust or drain from gases exhausted through the tail pipe of automobiles.
For an analyzer to measure automotive emissions accurately, each unit of the sampling system
must meet the following requirements.
1) Flow rate (monitored by pressure gauge) is as specified.
2) Air is not sucked into the units which are measuring automotive emissions.
3) It is designed not to allow dust or drain to enter the measuring unit.
If these requirements are not met, the instrument may provide different measuring readings from
actual concentration of emission gases. The following chart will help you locate the probable
cause of trouble or perform the routine maintenance and check for the sampling system.

3.2 Measuring unit
3.2.1 Outline
The measuring unit flows cleaned-up exhaust gases filtered by the sampling system into the
internal sampling cell. It optically analyzes CO, HC and CO2 contained in the gases and converts
them into electrical signal (voltage change). Use of solid state sensor and band pass filter makes
the measuring unit compact, which is composed of infrared ray light source, cell (sampling cell
only) and sensor unit. In addition, an O2 meter (option) uses galvanic cells. This section covers
troubleshooting which aids you in finding out the causes of trouble and taking its remedy when
the instrument is in trouble.

3.3 Electric system and PC board
3.3.1 Outline
The electric system is used to operate the double suction pump motor fan and each PC board
electrically.
The PC board incorporates the first stage IC's of AC amplifier circuits of CO, HC and CO2 in the
head amplifier (sensor unit). The amplifier PC board incorporates analog circuit, pump driven
circuit, solenoid valve driven circuit and motor driven circuit for CO, HC and CO2 and O2. CPU
and memory IC are mounted on the main printed board. Since the electrical system uses switching power for power supply, it is compact and lightweight.
This section provides the troubleshooting which helps you to determine if each part is properly
functioning.

7. UNIT REPLACEMENT
7.1 Infrared ray light source unit
Reason for replacement: Disconnected or deteriorated infrared ray light source, leak of sealing
gas, cracked window, improper readings due to contamination.
Check :
1) Visually check that the window is not dirty or the sealing pipe is not
damaged.
2) Detach the connector and check the winding resistance values of the
light source. The resistance values should be 3.9Ω±30%.
Procedures:
1)
2)
3)
4)
Detach the connector inserted into the repeating connector.
Remove 2-M4 screws which fix to the optical system base plate.
Remove the cell unit from the light source holder.
For assembly after repair or replacement, reverse the above procedure.

7.2 Sensor unit
Reason for replacement: Fluctuating indication due to damaged sensor, dirty and scratched B.P.F
and damaged motor.
Check:
1) Perform a visual check of window and B.P.F for stain or scratch.
2) Check that the sector rotates in a fixed cycle.
3) Check that the sensor signal is normal (See Page 9 ).
Procedures:
1)
2)
3)
4)
Detach the connector that is attached to the sensor unit.
Remove 2-M4 screws which secure to the optical system base plate.

7.3 Cell unit
Reason for replacement: Improper air tightness due to deteriorated O-ring.
Poor sensitivity due to contaminated inner surface of the cell.
Check:
1) Check that O-ring is free of crack or scratch.
2) Wipe the cell interior with a soft cloth.
Procedure;
Remove the infrared ray light source unit in Item 7.1 and sensor unit
in Item 7.2 and then remove the cell unit.
7.4 Switching power source unit
Reason for replacement: Indication lamp is not lit due to improper power supply voltage.
Check:
Check for power supply voltage of each unit. (See Page 8, 9.)
Procedure:
1) Detach the primary and secondary connectors of switching power
supply.
2) Remove claw that secures the case using a driver and the switching
power supply unit.
3) For assembly after replacement, reverse the above replacement
procedures.

7.5 Pump unit
Reason for replacement: Response is improper due to deteriorated diaphragm.
Check:
Attach a flowmeter to the drain port to check for the total flow rate
(drain and sampling port). If the total flow is below 3l/min, replace the
pump unit.
Procedures:
1) Detach the connector inserted into the amplifier PC board (CN3).
2) Remove 2-tapping screws securing to the case.
3) Remove a claw that secures the case using a driver and the switching
power supply unit.
4) For assembly after replacement, reverse the above procedure.

7.7 PC board unit
Reason for replacement: It is damaged due to shorted power supply.
Check:
Check for voltage and waveform at each part.
(For details, see Page 8 to 10.)
Procedures:
1)
2)
3)
4)
Detach the connector connected to each unit.
Remove 2-tapping screws that secure the PC board.
The amplifier is fixed to the main PC board by a single fixture (1).
For assembly after replacement, reverse the above procedure.
7.8 Oxygen sensor unit
Reason for replacement: This sensor unit is a consumable. Replacement should be performed
every year.
Check:
Measure the voltage at both ends of the sensor connector. Voltage
should be more than 10mV when sucking air. If not, replace it.
Procedures:
1) Detach the connector inserted into the amplifier PC board (CN8).
2) Turn the oxygen sensor counterclockwise to remove from the mounting board.
3) Wind a seal tape on the replacement oxygen sensor and screw in
clockwise.
