Electrical equipment marked with this symbol may not be disposed of in European public disposal systems after 12 August

2005. In conformity with European local and national regulations (EU Directive 2002/96/EC), European electrical equipment

users must now return old or end-of-life equipment to the manufacturer for disposal at no charge to the user.

ABB is committed to ensuring that the risk of any environmental damage or pollution caused by any of its products is minimized

as far as possible.

The European Union RoHS Directive and subsequent regulations introduced in member states and other countries limits the

use of six hazardous substances used in the manufacturing of electrical and electronic equipment. Currently, monitoring and

control instruments do not fall within the scope of the RoHS Directive, however ABB has taken the decision to adopt the

recommendations in the Directive as the target for all future product design and component purchasing.

1Sample requirements

1. Ensure the sampling point is as close as possible to the

wet-section and provides a thoroughly-mixed representative

sample.

2. Sample must contain <10 ppm suspended solids with a

particle size no greater than 60 µm. (If particle sizes exceed

60 µm, use a 60 µm filter.)

3. Sample temperature must be within the range 5 to 55 °C

(41 to 131 °F).

4. Sample flow rates must be within the range 100 to

300 ml/min. (6.10 to 18.30 cu in./min.) – recommended

150 ml/min (9.15 cu in./min.).

5. Sample pressure must not exceed 2 bar gauge (29 psi).

2Locating the wet-section

Referring to Fig. 1:

1. Locate the wet-section / transmitter indoors in a clean, dry,

well-ventilated, easily-accessible area.

2. Do not locate in rooms containing corrosive gases or vapors –

for example, with chlorination equipment or chlorine gas

cylinders.

3. Select a location not subject to strong electrical and magnetic

fields. If this is not possible (for example, where mobile

communications equipment is present), use screened cables

within flexible, earthed, metal conduit.

Note. If the measured sample temperature exceeds

55 °C (131 °F), the calibration valve opens automatically

to protect the dissolved oxygen sensor from thermal

overload. The valve closes after 30 minutes, but if the

sample temperature still exceeds 55 °C (131 °F) the valve

re-opens.

3Mounting the wet-section

Refer to Fig. 2 for wet-section dimensions. The wet-section weighs 4.5 kg (10 lb).

Referring to Fig. 3:

1. Mark the wall using the dimensions shown.

2. Drill and plug 3 holes Aand Bin the wall suitable for M6

or 1/4in. fixings.

3. Screw in top fixing A, leaving a gap of 20 mm (0.78 in.)

between the fixing head and the wall.

4. Hang the wet-section onto fixing A, ensuring it is retained

firmly against the wall.

5. Secure the wet-section to the wall using 2 fixings B.

Note. Clearance – the enclosure doors can open 180°. If mounting in a confined area, allow sufficient clearance for door opening.

4Connecting the sample lines

Referring to Fig. 4:

1. Connect the sample outlet tubing Ausing flexible PVC tubing 10 mm (3/8in.) ID fitted to barbed connector Bat the base of sample

outlet C.

2. Connect the drain tubing Dusing flexible PVC tubing 10 mm (3/8in.) ID fitted to the barbed connector at the base of drain valve E.

3. Connect sample inlet tubing F(typically stainless steel), 6 mm or 1/4in. OD (depending on customer requirement) to the bulkhead

connector G. Alternatively, nylon tubing 6 mm or 1/4in. OD could be fitted with suitable inner support fitting.

Note.

Sample inlet tubing, sample outlet tubing and drain tubing is customer-supplied.

Stainless steel is highly recommended for sample inlet lines as it prevents ingress of oxygen via the sample tubing. Nylon tubing

has a low oxygen permeability and can be used as an alternative to stainless steel, but stainless steel is the preferred option.

All sample drains must be kept as short as possible and be vertical to enable the sample to drain freely during a calibration routine.

Ensure the drain tubing outlet is open to atmosphere.

5Fitting the dissolved oxygen sensor

Referring to Fig. 5:

1. Remove the top from the dissolved oxygen sensor container.

2. Unscrew the protective cap from the rear of the dissolved oxygen sensor (take care not to damage the delicate membrane on the

oxygen sensor face).

3. Fit O-ring A(3/4in. ID) onto the connector body B.

4. Fit sensor Conto connector body Bensuring the pins and sockets are engaged correctly and tighten connector nut Donto the

sensor C.

5. Slide thrust washer Eover connector body B.

6. Fit O-ring G(7/8in. ID) onto the sensor (at the flowcell end), then insert the complete assembly into flowcell F.

7. Secure the sensor assembly by screwing clamping screw Hinto the flowcell firmly – use finger-pressure only.

Do not overtighten.

8. Ensure the mating surfaces of the (red) sensor connector Iand connector block connection Jare clean and completely dry, then

connect the sensor connector Ito the connector block connector Jfirmly and tighten 1 turn clockwise.

6Calibrating the analyzer

Perform a calibration via the Calibration Level or Advanced Level transmitter menus – refer to CI/AWT540-EN.

Caution. Only install the oxygen sensor immediately before use.

The sensor has a limited shelf life, do not store longer than 6 months.

Store the sensor in a cool environment.

Caution. Do not attempt to calibrate the analyzer until the wet-section and transmitter are fully installed and ready for operation.
