6.7 Replacing the Nitric Oxide Sensor

(For PCA Models 30, 35, 60 & 65)

Replace the Nitric Oxide sensor when it has expired (can no longer be calibrated).

NOTE: A "NX-SENSOR ERROR" displayed in the Sensor Status Screen does not necessarily mean that the sensor has expired. Before replacing the sensor, refer to Section 7.2 for other possible causes of the error.

Equipment Required:

•Small Flat Blade Screw Driver

•Nitric Oxide Sensor (Refer to Section 8.0)

•Nitric Oxide Sensor Filter (Refer to Section 8.0)

Procedure:

1.Remove the analyzer’s rear case and lay it aside (refer to Section 6.2).

2.Carefully pull the printed circuit board off the rear of the Nitric Oxide sensor (see Figure 6-2).

3.Push in and turn the sensor counterclockwise (watching the notch on top) until it stops; then pull the sensor out of its housing.

4.Install a new sensor by first pushing it into its housing, and then turning it clockwise until it locks in place.

5.Install the circuit board, which was removed in Step 2, onto the rear of the sensor.

6.Reassemble the analyzer and allow the sensor to be connected in the circuit for at least 4 hours before continuing.

7.Place the analyzer in an area of fresh air and turn it ON.

8.Calibrate the analyzer per Section 5.0.

6.7.1 Replacing the Nitric Oxide Sensor Filter

Replacing the orange filter on the Nitric Oxide sensor once a year could increase the life of the sensor.

Procedure:

1.Remove the Nitric Oxide sensor per Section 6.7.

2.Pry the orange filter from the Nitric Oxide sensor and replace it with a new one.

3.Reinstall the sensor.
