6.8 Replacing the Carbon Monoxide Sensor

(For PCA Models 20, 25, 30, 35, 50, 55, 60 & 65)

Replace the Carbon Monoxide sensor when it has expired (can no longer be calibrated).

NOTE: A "CO-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

•Carbon Monoxide Sensor (Refer to Section 8.0

•Carbon Monoxide 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 Carbon Monoxide 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.Remove the wire jumper from the pins of the new sensor.

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

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

7.Reassemble the analyzer; then allow the sensor to be connected in the circuit for at least 1 hour before continuing.

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

9.Calibrate the analyzer per Section 5.0.
