W A R N I N G

C A U T I O N

Personal injury hazard. Instruments or components are heavy. Use assistance to install or move. Make sure that the wall mounting is able to hold 4 times the weight of the equipment.

Wherever the analyzer is to be mounted, it is important to note that it must be placed in an upright position with the transmitter at the top. It is recommended to use a spirit level to ensure that the analyzer is correctly positioned and not leaning to one side or forward. This is essential to guarantee the accuracy of the analyzer.

C A U T I O N

Panel mounting

Mount the analyzer using the fixation holes located around the outside of the analyzer.

Wall mounting

Use the wall mounting kit to fix the instrument to the wall. The distance between the two pieces is 460 mm.

C A U T I O N

It is extremely important to respect this gap of 460 mm to avoid bending the cabinet out of shape while fitting.

Mains power connection

W A R N I N G

No intervention should be made on the instrument without first switching off the power.

The electrical installation should be carried out by duly qualified personnel. A supply voltage of 100-240 VAC is acceptable without changing the configuration. The power supply terminals can be removed from their housing to make connection easier.

For safety reasons, it is imperative to respect the working procedure below:

• Use a three-wire power cable (live + neutral + earth), sized for supplying the required power.

• The instrument should be connected to the mains via a circuit-breaker or fuse whose value should be less or equal to 20 A. It should be located in proximity and be identified. This connection should cut-off the live and the neutral when electrical problems occur or when the user wishes to intervene inside the instrument. On the other hand, the earth conductor should always be connected.

The main cabinet should be open with access to the interior.

1. Pass the power cable through the cable gland located at the back left of the bottom of the

cabinet.

2. Open the back of the local controller box (No. 11 in Figure 1 on page 6) by unscrewing the

6 screws.

3. Unscrew the two holding screws on the upper left and right side of the box, and allow it to rotate

down to reveal the back of the transmitter. The cable gland for the power cable is located left and nearest to you.

English

4. Unscrew the cable gland nut, pass the power cable through it, and then up through the cable gland and into the transmitter (No. 2). Screw back the cable gland nut to secure the power cable.

5. Open the transmitter front door by unscrewing the four holding screws.

6. Swing open the door (it is hinged to the left) to reveal the inside of the transmitter.

7. Remove the metallic shielding plate (No. 1) protecting access to the main board.

8. Remove the power supply connector (No. 3) and note where the earth, neutral and live (E, N, L)

must be connected.

9. Connect the power supply cables to the connector.

10. Put the connector back in place (No. 4).

11. Replace the metallic shielding plate, ensuring it is in front of the power cable just installed.

External communications connection

1. Run the communications cable through an external cable gland on

the bottom of the cabinet, and into the analyzer.

2. Pass it through the cable gland located right and farthest from you

on the base of the transmitter, so it appears inside the transmitter through the left front cable gland.

3. Connect the communication cable as indicated. Connection is the

same on the CPU board for both the JBUS/ MODBUS and PROFIBUS options.

4. Close the transmitter door and secure in place with the 4 screws.

5. Put the local controller box back in its normal position and secure in

place with the 2 holding screws.

Input/Output connections

Before using any of the cable glands, perforate first with a screwdriver. To ensure a good seal, the external diameter of the cables should be between 5 and 7 mm. The nomenclature given in the connections column of the following table refers to the same nomenclature that is printed on the I/O board against each available connection.

On completion, close the local controller box (No. 11 in Figure 1 on page 6) and secure in place with the 6 screws.

Sample tubes installation

Connecting the sample

Use new tubes for connections during installation

• Exterior Ø: 6 mm exactly (or ¼'')

• Material: polyethylene or PTFE or FEP

• Flow rate: 6 to 9 L/hour

English

• Pressure: 0.2 to 6 bar (8-100 psig)

• Sample acidity: sample acidity should not be more than 300 ppm CaCO

• Temperature: 5 to 45°C

At this stage of the installation, make sure that the flow valve is closed. Connect the pipes by inserting them into the quick release connections found on the bottom of the analyzer under the sampling block (No. 14 in Figure 1 on page 6). Be sure that the sample line is correctly flushed before any connection to avoid particle injection into the hydraulic system. If particulate matter is present in the sample, pre-filtration is necessary. A filter should be inserted in the sample line. One is available as an option. Connect one inlet and one outlet per channel.

Connecting the drain tube

The drain outlet is located on the bottom of the analyzer. A 12 x 17 mm pipe is delivered with the analyzer and should be connected to the drain outlet at one end and the other fed to a drain for sample evacuation.

Reagents installation

The canisters are installed in the canister holder (No. 10 in Figure 1 on page 6).

1. Prepare the reagents.

2. Install and connect the conditioning solution (diisopropylamine).

3. Install and connect the reactivation solution (blue R label).

4. If you have this option, install and connect the auto calibration solution

(yellow CAL label).

Magnetic stirrer installation

1. On the front of the panel, remove the plastic bag from the overflow vessel (No. 5 in Figure 1

on page 6).

2. Remove the magnetic stirrer from the bag and install it in the overflow vessel.

Reagents volume declaration

Note: As you will now be using the analyzer menus to input data, it may be useful to familiarize yourself with the data entry procedures by reading the section entitled User interface on page 12.

name of the channel to regulate is displayed.

5. The analyzer automatically empties and refills the overflow vessel to determine the flow rate

which is displayed on screen.

English

6. The flow rate for each channel should be 6 to 9 L/hour.

7. Using a screwdriver, regulate the channel’s sample flow (No. 3 in Figure 1 on page 6) by turning

counter-clockwise to increase the flow rate or clockwise to decrease the flow rate.

8. The process is repeated until the flow is correctly regulated for the channel. At this point select OK.

9. The system then allows you to regulate the next channel until all flow rates have been set for the

configured channels.

10. Once all flow rates for the configured channels have been set, an Action completed message will be displayed. Select Esc to exit.

Sample pH conditioning check

2. On the analyzer, press Start on the main menu to start the measurement process.

3. For each channel, check that the pH value of the sample after conditioning is greater than 10.5. If

not, check the quality of the conditioning product used.

Cationic applications

1. With a calibrated pH sensor, measure the pH of the sample for each channel outside of the

analyzer.

2. The analyzer measurement sequence will be factory set depending on the number of configured channels (e.g. 1 2 3 4 * for a 4-channel analyzer or 1 2 * for a 2-channel analyzer). Verify this sequence is correctly setup (see Sequence on page 18 for more details).

3. Set the following measurement timings (see Measure steps on page 15):

• CYCLE TIME to 11 min

• ON LINE MEAS to 8 min

• SEARCH STAB to No

4. For each channel, determine the gas injection time ratio depending on the sample pH. Enter this value into the analyzer as described in Total gas/water ratio (cationic applications only) on page 15. The standard values are:

• pH = 2.0 - Tgas/Twater ratio = 180%

• pH = 2.3 - Tgas/Twater ratio = 80%

• pH = 2.6 - Tgas/Twater ratio = 50%

• pH = 2.9 - Tgas/Twater ratio = 30%

• pH = 3.5 - Tgas/Twater ratio = 15%

• pH = 4.0 - Tgas/Twater ratio = 10%

5. Install the same pH sensor in the center position of the measurement chamber (No. 2 in Figure 1 on page 6).

6. On the analyzer, press Start on the main menu to start the measurement process.

7. For each channel, measure the pH in the conditioned sample to check if the pump ratios are

Measurement

Targeted pH (non-cationic applications only)

Select the pH option and enter the target pH value for your application. The measured pH value of the sample in the measuring cell should be within ±0.2 pH of the target.

Total gas/water ratio (cationic applications only)

1. For each channel, enter the ratio of gas to water to minimize the DIPA consumption. This is part

of the installation procedure and is explained in more detail in the installation section of the full user manual.

Measure steps

1. Select the MEASURE STEPS option to set up the measurement timings.

Measure steps - single channel

1. The on line measurement time defines the measurement time of the sample and how often the

measurement values are stored in memory. For a single channel configuration, it is recommended to leave this time at the default value of 10 minutes.

2. If smart rinsing is required after a calibration, grab sample or sensor reactivation, set this parameter to Yes and define the maximum rinse time.

Measure steps - multi channel

1. The on line measurement time is the time when the analyzer displays the true sodium

measurement. This value must be at least 1 minute and less than the cycle time.

2. If smart rinsing is required after a calibration, grab sample or sensor reactivation, set this parameter to Yes and define the maximum rinse time.

3. The cycle time is the total measurement time for each channel and cannot be less than 10 minutes.

4. After a change of measurement channel, for a manual mode with a fixed cycle time, set the search stability mode to No. For an automatic mode which minimizes the cycle time, set this parameter to Yes.

Reactivation frequency

1. Select the ACTIVAT. FREQ option to set the time period between electrode reactivation. When

this time period expires, the electrode is reactivated automatically with an injection of a small amount of reactivation solution.

2. Set the reactivation mode to either a Frequency or a fixed date.

3. If set to frequency, the recommended time period is 24 hours so that the electrode is reactivated

on a daily basis.

English

Note: If this value is set to zero, then no electrode reactivation will take place during the calibration process and as such the calibration may be inaccurate. It is highly recommended to set this parameter to 24.

4. If set to a fixed date, define the day and time of the week when reactivation takes place. Set the

day of the week to an asterisk if reactivation is not to take place on that day.

Note: The attribute variable cannot be applied to Output 0, which is reserved for the continuous live output signal.

Event indication

1. Select the EVENT INDICATION option in the mA Outputs menu to display the options available

for event setting.

2. Select the option for which you want to set an event.

3. Define the attribute for the event. This is one of the outputs or None.

4. The MODE can be either a Preset val or Frozen.

5. If a preset value is chosen, you will be required to enter the value of the analog output that will be

forced, when that event occurs.

Test

This option allows you to enter a value into the mA field. Press the Enter function key to force this value on all the analog outputs. The value can then be verified with the use of a multimeter connected to the analyzer.

RS485 (or PROFIBUS)

Note: If the PROFIBUS option has been installed, then the menu option will show PROFIBUS rather than RS485, and the PROFIBUS parameters will need to be installed.

1. Select the RS485 option to set up the parameters for the communications protocol.

2. Press the Enter function key to accept each data element.

3. On completion, press the Esc function key to return to the user setup screen.

English

Sample channels

Select the SAMPLE CHANNELS option to set up the channel parameters.

Number of channels

1. If the number of channels parameter is changed, an activation key will be required before the

additional channel is recognized.

Channel activation

Using the Up and Down Arrow keys, define whether the channel is active (Activ) or inactive (Inactiv).

Sequence

The sequence defines the channel order in which samples are measured.

1. Only configured channels can be used in the sequence. For example for a 3-channel analyzer only values 1,2 and 3 are available.

2. Up to 12 sequences can be defined. If a channel has been deactivated, but is still in the sequence, it is simply ignored and the next channel in sequence is measured.

3. If there is no sample on a programmed channel, the analyzer will detect this and after 3 minutes move on to the next channel in sequence. The channel on which the sample is missing will be assigned the alarm sample x flow < min (where sample x is the name of the channel).

4. If the analyzer is stopped manually from the keyboard, it restarts from the same place in the sequence.

5. In the event of a power failure, when restarted the analyzer with start at the beginning of the sequence.

Channel names

Define the name of the channel with free-format alphanumeric text up to a maximum of 8 characters.

CALIBRATION

The instrument cannot be calibrated until at least one complete measurement cycle has been successfully performed. An attempt to calibrate the instrument before this will result in a “Not authorized” message being displayed.

In order to obtain accurate measurement results, the analyzer should be calibrated on a regular basis. Two basic methods of calibration are available:

• Manual calibration - The user can manually perform a calibration on an ad-hoc basis.

• Automatic calibration - Parameters can be set up so that the analyzer will perform a calibration

automatically on pre-defined days at a pre-defined time (see Automatic calibration setup on page 20). This type of calibration is always done using known calibration solution concentrations.

Note: Before starting a calibration It is very important to ensure that the Reactivation Frequency parameter (see

Reactivation frequency on page 15) is greater than zero. If set to zero, the electrode reactivation process will not

take place during calibration and as such the measurement results may well be out of limits.

Calibration solution concentrations

N O T I C E

The maximum concentration value for any calibration solution cannot be greater than 2000 ppm. Any value superior to this is outside the analyzer specifications and cannot be processed.

Manual calibration

For a manual calibration, the calibration solutions must be between 100 ppb and 2000 ppm and must respect the following rules:

English

• LOW CAL SOL must be ≥ sample concentration of Na+ and a minimum of 100 ppb

• HIGH CAL SOL = (LOW CAL SOL x 10)

Example 1: sample concentration of Na+ = 20 ppb → LOW CAL SOL = minimum value = 100 ppb Na → HIGH CAL SOL = (100 ppb x 10) = 1000 ppb Na

Example 2: sample concentration of Na+ = 450 ppb → LOW CAL SOL = ≥ sample concentration of Na+ = 500 ppb Na → HIGH CAL SOL = (500 ppb x 10) = 5000 ppb Na

Note: The values LOW CAL SOL and HIGH CAL SOL must be entered into the system (see One point calibration on page 20 or Two point calibration on page 20).

Automatic calibration

For an automatic calibration, the calibration solution must be between 10 ppm and 2000 ppm and must respect the following rules:

• CAL SOL minimum = 10 ppm

• CAL SOL = (sample concentration of Na+ x 1000)

Example 1: sample concentration of Na+ = 0.1 ppb → CAL SOL = minimum value = 10 ppm Na

Example 2: sample concentration of Na+ = 1 ppm → CAL SOL = (1 ppm x 1000) = 1000 ppm Na

Note: The value CAL SOL must be entered into the system (see Automatic calibration setup on page 20)

Start calibration

Select the START CALIBRATION option to calibrate the analyzer manually.

Calibrate known addition

1. Select the CAL.KNOWN ADDITION option to calibrate the analyzer by mixing the sample with a

known concentration of calibration solution. The concentration of the calibration solution is defined in Automatic calibration setup on page 20.

2. The instrument first checks that the volume of calibration solution remaining is enough. If not, a

warning alarm is activated and the instrument returns to normal measurement with the original parameters.

3. If the volume of solution is OK, the background point measurement (P0) to be used as the base

measurement value is taken. This is the measurement against the sample before any additions of the calibration solution have been made.

4. The measurement must be stable and less than 1 per thousand of the calibration solution

concentration, otherwise the instrument returns to normal measurement with the original parameters. Provided the measurement is OK, the P0 measurement details are displayed on screen.

5. If the reactivation frequency parameter is not zero (as is highly recommended), the electrode will

be reactivated.

6. When the reactivation process is complete, the overflow vessel is rinsed to remove all traces of

sample.

7. After rinsing, the overflow vessel is re-filled with sample plus 2mL of the calibration solution.

8. The sample is then measured and the details displayed against P1.

9. When the measurement is stable, the details are displayed at the top of the screen against

measurement P1.

10. The overflow vessel is then rinsed and re-filled with sample plus 20mL of the calibration solution.

11. This sample is then measured and the details displayed against P2.

12. Once the final measurement is stable, the offset and slope for this calibration are calculated.

English

13. The default values of the offset and slope are displayed along with the calculated values for the

last and current calibration.

14. A message is displayed indicating the success or failure of the calibration.

One point calibration

This process requires that a calibration solution of known sodium concentration is available. Refer to

Calibration solution concentrations on page 18 for information regarding the concentration of the

calibration solution.

1. Select the MAN.OFFSET CAL option to start the one point calibration process.

2. If necessary, enter the concentration of the calibration solution, and select START to initiate the

calibration process. Then, provided the reactivation frequency parameter is not zero (as is highly recommended), the electrode is reactivated. On completion this is followed by a rinsing of the overflow vessel.

3. When prompted, fill the overflow vessel with the calibration solution and select OK to start the measurement.

4. The calibration solution is measured and the results displayed.

5. Once the final measurement is stable, the offset for the calibration is calculated.

6. A message is displayed indicating the success or failure of the calibration.

Two point calibration

This process requires that two calibration solutions of known sodium concentrations are available. Refer to Calibration solution concentrations on page 18 for information regarding the concentrations of the calibration solution.

1. Select the MAN.OFFSET+SLOPE CAL option to start the two point calibration process.

2. If necessary, enter the concentrations of the calibration solution, and select START to initiate the

3. The process is then very similar to the one-point calibration above, except after the instrument measures the low value calibration solution, the overflow vessel will be rinsed and you will be asked to fill it with the high value calibration solution.

4. A message is displayed indicating the success or failure of the calibration.

Automatic calibration setup

This allows the analyzer to be automatically calibrated at pre-defined and regular intervals. The process is the same as described in Calibrate known addition on page 19 except it is initiated

automatically at the pre-defined time.

1. Select the AUTO. CAL. SETUP option to access its sub-menu and set the calibration parameters.

2. Turn the automatic calibration on or off by selecting Yes or No as appropriate. Note that even if this is set to Yes, it is still possible to calibrate the analyzer manually if required.

3. CAL.SOL defines the concentration of the calibration solution. Refer to Calibration solution

concentrations on page 18 for information regarding the concentration of the calibration solution.

4. MODE can either be set up to a fixed date or to a specified Frequency.

5. If the mode is set to fixed date, enter the day(s) of the WEEK when the calibration will be

performed. Set the day to an asterisk to skip that day.

6. Set the HOUR field (HH:MM:SS format on a 24 hour clock) to the time the automatic calibration should start.

English

7. If the mode is set to frequency, then the week and hour data fields will be replaced by a TIME PERIOD field. Enter the calibration frequency in hours into this field.

8. Finally, in the CALIB ON field, select the channel to be used for calibration. The number of

channels available will depend on the number of channels configured for the instrument. The sample concentration being measured on this channel must be less than 1 per thousand of the calibration solution concentration, otherwise an error is signalled during calibration.

Calibration results

After the slope and offset have been calculated, the default parameters, last calibration details and current calibration details are displayed, along with a “Calibration ok” or “Calibration error” message. The criteria for accepting or rejecting the calibration is as follows:

• The slope must be within ± 10% of the standard slope

• The offset must be within ± 59 mV from the reference point

If the calibration is accepted, the parameters are updated and the instrument returns to the normal measurement mode after a short delay.

If the calibration is rejected an alarm is set and the parameters remain unchanged. After a short delay the analyzer returns to the normal measurement mode.

For details of the calibration results, select the calibration loggings option as described below.

Calibration loggings

1. Select the CALIBRATION LOGGINGS option to view historical information about previous

calibrations.

2. Use the Arrow key to scroll through the data.

Custom adjustment

1. Where the analyzer displays values that are slightly above or below the expected value, the CUSTOM.ADJ option can be used to manually adjust the measurement value.

2. Enter a positive or negative value which will be added to the measurement value. This option can

only be used to make minor adjustments. The allowable adjustment value is between -0.1 ppb and +0.1 ppb.

3. If the displayed and expected values differ significantly, the analyzer should be recalibrated.

Temperature calibration

1. Select the TEMPERATURE CALIB. option to calibrate the temperature electrode.

2. The measured temperature reading is displayed in the raw temp field.

3. Take a temperature reading with a certified thermometer and press OK to continue.

4. Then enter this temperature reading into the CAL.TEMP. field.

5. Press OK to calibrate.

VERIFICATION

This option allows you to verify the measurement using a solution of known sodium concentration. Concentration of the known solution should be higher than 20 ppb (100 ppb is recommended) to ensure a preparation step in a range with lower risks of contamination.

1. First enter the concentration of the verification solution in the VALID. SOL field.

2. Select START to commence the process.

3. The first step of this cycle allows the reactivation of the electrode. The message SENSOR ACTIVATION is displayed. Select Yes to reactivate the sensor. Select No if time is more

important than accuracy.

English

4. The reactivation process is automatically followed by a rinsing of the overflow vessel and

measuring cell using the process sample. Upon completion of the rinsing step, the analyzer is ready for the first manual step in the cycle.

5. Place the lid of the overflow vessel on the side and pour approximately 200 mL of the solution

into the overflow vessel, as prompted on screen. Manual introduction is complete when the sample overflows at the back of the overflow vessel.

6. Place the lid back on top of the overflow vessel and select OK to start the measurement. The

display switches back to the main measurement screen and displays the measurement value.

7. Once measurement of the solution is complete, the measured value and time will be displayed against verif. s. This should be almost identical to the value entered in the VALID. SOL field previously.

The value displayed in gap, will be the percentage difference between the concentration of the verification solution entered in the VALID. SOL field, and the concentration measured by the instrument. If this value is too high, then a calibration of the analyzer is recommended.

8. Once the cycle is complete, the analyzer automatically reverts back to standard measurement mode.

9. Select Main to go back to the main measurement screen.

GRAB SAMPLE

Similar to the verification process, this option allows measurement of a sample of your choice. Before starting this process, ensure you have a sample of approximately 200 mL to measure.

Note: It is recommended that the grab sample should have a concentration of > 10 ppb and should be at the same temperature as during calibration for better accuracy. Under these conditions, measurement with manual introduction gives 5% accuracy from 10 ppb to 10 ppm at a temperature which is within ± 5 °C of the temperature during calibration.

1. The first step of this cycle allows the reactivation of the electrode. The message SENSOR ACTIVATION is displayed. Select Yes to reactivate the sensor. Select No if time is more

important than accuracy.

2. The reactivation process is automatically followed by a rinsing of the overflow vessel and measuring cell using the process sample. Upon completion of the rinsing step, the analyzer is ready for the first manual step in the cycle.

3. Place the lid of the overflow vessel on the side and pour approximately 200 mL of the solution into the overflow vessel, as prompted on screen. Manual introduction is complete when the sample overflows at the back of the overflow vessel.

4. Place the lid back on top of the overflow vessel and select OK to start the measurement. The display switches back to the main measurement screen and displays the measurement value.

5. Once measurement of the solution is complete, the measured value and time will be displayed against grab s.

6. Once the cycle is complete, the analyzer automatically reverts back to standard measurement mode.

7. Select Main to go back to the main measurement screen.

MAINTENANCE/DIAG.

Reagent changes

This procedure is applicable to each change of reagent solution. It allows the regulation of the volumes of solutions in the bottles. The analyzer consistently checks the consumption of these solutions, triggering an alarm when these levels get too low. This option must be selected each time a solution is refilled or changed to reset the measurement parameters.

Note: The conditioning reagent and electrolyte consumption are approximate measurements, so a discrepancy between measurement and actual consumption may occur. The conditioning solution consumption has been measured for a pH of 11.2 at an ambient temperature of 25°C.

English

Adjust bottle volumes

This option should be used to set the default values of reagents or when bottles are being used that are not full (see Bottles full on page 23).

1. Select the ADJUST BOTTLE VOLS. option to set the reagent volumes.

2. Enter the volumes for the conditioning solution, reactivation solution, calibration solution and

electrolyte in milliliters.

3. Press Select to move from one field to another to keep the value displayed, or press Enter on

completion of a field to move to the next.

4. Press the Esc function key on completion.

Priming tubes

1. After refilling the bottles (reference electrolyte, calibration solution and reactivation solution)

and/or after exchanging the empty bottle of conditioning reagent with a new one, select the

PRIMING TUBES option. This will set off the process to purge and refill the tubes.

2. Press the Esc function key at any time to abort the process and return to the menu.

Bottles full

1. If the bottles of reagent are full, select Yes and the default values for the volumes will be set.

These values can be viewed and modified by selecting the ADJUST BOTTLE VOLS. option in the menu. If you select No to this option, you will manually have to enter the correct values using the ADJUST BOTTLE VOLS. option.

Test accessories

This option allows you to check that a number of accessories, as well as the alarm relays and logical inputs are functioning correctly.

Sensor reactivation

Usually, the electrode is reactivated automatically based on the time delay set in Reactivation

frequency on page 15. This option allows for a manual reactivation.

Extended stop

If the instrument is not to be used for an extended period of time, select this option to shut the analyzer down in a controlled manner.

1. Place all the tubes in demineralized water for cleaning.

2. Press OK to continue.

3. A progress bar will be displayed whilst the shut down is being performed.

4. On completion, you will be informed to remove and store the electrodes.

5. Press ESC to exit.

Startup

This process guides you through various steps required to set the instrument up for initial measurements, or to restart after a long period of inactivity. This includes regulating the sample flow and purging the pumps of reagent.

1. Regulate the flow of the sample to ensure a slight overflow into the overflow vessel.

2. Select OK to continue. You will then be required to regulate the flow on the next configured

channel.

3. On completion, an Action completed message will be displayed. Select Esc to exit.

Anschluss der Stromversorgung

W A R N U N G

Es dürfen keinerlei Eingriffe am Instrument vorgenommen werden, ohne dass zuvor die Stromversorgung abgeschaltet wird.

Die elektrische Installation sollte von qualifiziertem Personal vorgenommen werden. Ohne Änderung der Konfigurierung an eine Stromversorgung von 100-240 VAC angeschlossen werden. Die Kontakte der Stromversorgung können zur Vereinfachung der Anschlussarbeiten aus ihrem Gehäuse entnommen werden.

Die folgenden Arbeitsverfahren müssen aus Sicherheitsgründe eingehalten werden:

• Verwenden Sie ein dreiadriges Netzkabel (Phase + Nullleiter + Erde), das der erforderlich Leistung

angemessen ist.

• Das Instrument sollte über eine Unterbrechungsstelle oder eine Sicherung an die

Stromversorgung angeschlossen werden, deren Werte über 20 A liegen. Diese sollten sich in der Nähe des Instruments befinden und gekennzeichnet werden. Dieser Anschluss muss die Phase und den Nullleiter bei elektrischen Problemen oder bei Eingriffen im Inneren des Instruments unterbrechen. Der Erdunsleiter muss jedoch immer angeschlossen bleiben.

Das Hauptgehäuse sollte offen sein.

1. Führen Sie das Netzkabel durch den Kabeldurchlass links unten am Boden des Gehäuses.

2. Die rückwärtige Abdeckung des lokalen Steuerungsgehäuses (Nr. 11 in Abbildung 1 auf Seite 27)

Installation der Probenleitungen

Probe anschließen

Verwenden Sie bei der Installation für alle Anschlüsse neue Leitungen.

• Außen Ø: 6 mm exakt (oder ¼'')

• Material: Polyäthylen, PTFE oder FEP

• Flussrate: 6 bis 9 l/Stunde

• Druck: 0,2 bis 6 bar (8-100 psig)

• Säuregrad der Probe: Der Säuregrad der Probe sollte 300 ppm CaCO3 nicht übersteigen

• Temperatur: 5 bis 45°C

Stellen Sie sicher, dass das Flussventil in dieser Phase der Installation geschlossen ist. Die Leitungen anschließen. Diese dazu in die Schnellanschlüsse, die sich auf der Unterseite des Analysators unter dem Problenblock (Nr. 14 in Abbildung 1 auf Seite 27) befinden, einführen. Stellen Sie sicher, dass die Probenleitung vor dem Anschließen ordnungsgemäß durchgespült worden ist, um zu verhindern, dass Partikel in das Hydrauliksystem des gelangen. Falls Partikel in der Probe vorhanden sind, ist eine Vorfilterung erforderlich. In die Probenleitung sollte ein Filter eingesetzt werden. Ein Filter kann als Option geliefert werden. Schließen Sie einen Einlass und einen Auslass pro Kanal an.

Abflussleitung anschließen

Der Auslass befindet sich am Boden des Analysators. Mit dem Analysator wird eine Leitung 12 x 17 mm geliefert; ein Ende sollte am Auslass angeschlossen und das andere zum Abfluss der Probe geführt werden.

Installation der Reagenzlösungen

Die Kanister werden in die Kanisterhalterung (Nr. 10 in Abbildung 1 auf Seite 27) eingesetzt.

1. Die Reagenzlösungen vorbereiten.

2. Installieren Sie die Konditionierungslösung (Di-Isopropylamin) und schließen

Sie sie an.

3. Installieren Sie die Reaktivierungslösung (blaues Etikett R) und schließen Sie

sie an.

4. Installieren Sie die Auto-Kalibrierungslösung (gelbes Etikett CAL) und

schließen Sie sie an, falls diese Option vorhanden ist.

Installation des Magnetrührwerks

1. Entfernen auf der Front des Paneels den Kunststoffbeutel vom Überflussgefäß (Nr. 5 in

Abbildung 1 auf Seite 27).

2. Entnehmen Sie das Magnetrührwerk aus dem Beutel und installieren Sie es im Überflussgefäß.

Angabe des Reagenzlösungsvolumens

Hinweis: Da Sie jetzt die Menüs des Analysators für die Dateneingabe verwenden werden, empfiehlt es sich, dass Sie sich zuvor mit den Verfahren für die Dateneingabe vertraut machen und dazu den Abschnitt

Benutzeroberfläche auf Seite 33.
