25 - 6

ETC00781(4) Series 100 e 02/2004

25.2.2 Removing the Sensor

P Take the consumed sensor out of the fitting.

P Take off the stopper from new sensor and place the new sensor into the fitting, so

that the name plate is at the top of the sensor.

P Close the consumed sensor with the stopper and send it back to our factory.

25.2.3 Reinstalling the Sensor

a) Oxygen Measurement without IR - channel

P Put the fitting with the (new) sensor onto the support, move to the stop and screw with

the two fastening screws (phillips screws, see Fig. 25-3)

P Fix the sensor with a cable tie to the support (see Fig. 25-3).

P Connect the connector for the sensor to “P2” of circuit board “OXS” (see Fig. 25-5 / chapter 18.).

P Insert the complete support (see Fig. 25-3) into the analyzer and fix it with the two

allen screws (fastening screws, see Fig. 25-2).

P Reconnect all gas lines to the fittings (see Fig. 25-2 and Fig. 25-3).

Do not interchange gas inlets and gas outlets.

P Reconnect all electrical connections between OXS and BKS (X5 and X7, see chapter 18.).

P Perform a leakage test (see chapter 22.) and set the sensor (see chapter 25.2.4).

b) Combined IR / Oxygen Measurement

P Put the fitting with the (new) sensor onto the support, move to the stop and fix it with

the two fastening screws (see Fig. 25-4)

P Connect the connector for the sensor to “P2” of circuit board “OXS” (see Fig. 25-5 / chapter 18.).
