Installation

WARNING

The analyzer should only be assembled by qualified staff. Mains power should only be connected once

installation has been completed and checked

Mounting the analyzer

WARNING

Do not connect power prior to mounting and plumbing the instrument.

CAUTION

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.

CAUTION

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.

English 7

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.

CAUTION

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

Mains power connection

WARNING

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 7) 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.

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.

8 English

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.

Connections Function

Re1 to Re6 User relays - see Alarms on page 17 for more information on the relays

Re7 Warning alarm

Re8 System alarm

In2 For remote calibration

In4 to In7 By-pass channel measurement (channel 4 - 1 respectively)

Iout0 Used for the current measurement signals

Iout1 to Iout7 Can be freely linked to different parameters like measurement, temperature - refer to the section

entitled mA outputs on page 18 for details

On completion, close the local controller box (No. 11 in Figure 1 on page 7) 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

• Pressure: 0.2 to 6 bar (8-100 psig)

• Sample acidity: sample acidity should not be more than 300 ppm CaCO3

• 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 7). Be sure that the sample line is correctly flushed

before any connection to avoid particle injection into the hydraulic system. If particulate matter is

English 9

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 7).

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 7).

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.

1. Open the sample valve and check that there is no leakage in the hydraulic path.

2. Power on the analyzer.

3. Select the Menu option from the display.

4. Select MAINTENANCE/DIAG. from the main menu and press Enter.

5. Select the REAGENT CHANGES option and press Enter.

6. Set the BOTTLES FULL parameter to Yes and press Enter.

7. Press Esc to return to the MAINTENANCE/DIAG. menu.

Flow rate adjustment

1. From the MAINTENANCE/DIAG. menu select START UP and press Enter.

2. First, the system automatically primes both the calibration and reactivation tubes.

3. Check that there are no air bubbles in the reagent tubes for reactivation and auto calibration.

4. The next step allows you to regulate the sample flow rate on each measurement channel. The

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.

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 7) 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.
