Removal of these modules - with the exception of the measuring cell - is self-explanatory.
6.2 Sensor module
6.2.1 Design
The sensor module consists of the following function units: O
2
sensor, sensor electronics,
supporting plate (metal bracket), and the gas path components mounted on the bracket.
6.2.2 Installation and removal of the sensor module
The sensor module is not particularly susceptible to faults. If a component of the sensor
module is faulty as a result of a material fault or incorrect operation, the complete sensor
module must be replaced. It is then replaced by an equivalent module. Individual
components cannot be replaced.
1. Release the internal capillary link at the sample gas inlet.
2. Release the internal hose connection at the sample gas outlet.
3. Release the hose connections on the flowmeter.
4. Loosen the four socket screws (M6) of the metal bracket, and then slide this to the side
until the screw heads are free.
5. Remove the ribbon cable from the motherboard.
6. Remove the RS232 communication cable from the sensor electronics.
7. Remove the metal bracket.
8. To install, carry out the above steps in reverse order.
