General presentation

The TPM870 Turbidity Pump Module is used to interface a turbidimeter

fitted with an analogue measurement output (example the 2100AN IS

turbidimeter from Hach) and a Titration Workstation of the TIM8xx/

TIM9xx range or a ION450/ION570 Ion Analyser.

The TPM870 allows to automate turbidity measurements in association

with pH and conductivity measurements and a potentiometric titration

like water hardness determination for example.

With a PC connected to the Titration Workstation and the TitraMaster 85

PC software, the analysis can be fully automatised and the

measurements collected on the PC.

Présentation générale

Le Module Pompe Turbidité TPM870 est utilisé pour interfacer un

turbidimètre équipé d'une sortie de mesure analogique (exemple : le

turbidimètre 2100AN IS de chez Hach) avec une Station de Titrage de la

gamme TIM8xx/TIM9xx ou un Analyseur d'Ions ION450/ION570.

Le TPM870 permet d'automatiser la mesure de la turbidité en associa-

tion avec la mesure de pH, de conductivité et un titrage potentiométrique

comme la détermination de la dureté de l'eau par exemple.

Avec un PC connecté à la Station de Titrage et le logiciel PC

TitraMaster 85, l'analyse peut être entièrement automatisée et les

mesures récupérées dans le PC.

1. Setting up

The TPM870 instrument has been developed to meet the requirements of

electrochemical applications dedicated to water analysis. It is therefore

aimed at experienced users who have the knowledge required to operate

the instrument and implement the security instructions enclosed. We

accept no responsibility for using this measurement system (including

peripheral devices) under conditions that are not specified in this User's

Manual. This system must not, under any circumstances, be used to

perform tests on living beings.

1.1 Equipment used

. A TPM870 Turbidity Pump Module to add turbidity measure

automation to TitraLab or MeterLab system configurations (see table

below), R21T112 (in 230 V) or R21T113 (in 115V).

. A turbidimeter with an analogue measurement output (example:

2100AN IS turbidimeter from Hach).

. A manual Flow Cell Kit for 2100AN IS turbidimeter from Hach.

. < 0.1, 20, 200, 1000, 4000 and 7500 NTU standards.

1.2 Hydraulics circuit

1.2.1 Operation principle

The sample is driven into the turbidity flow cell (3) with pump (2) after

electrovalve (1) has opened. The sample is evacuated to a waste.

Rinsing water is driven into the turbidity flow cell (3) with pump (2) after

electrovalve (4) has opened. Rinsing water is evacuated to a waste as

for the sample.

Electrovalves (1) and (6) and pump (2) are monitored via the TTL

commands of the instrument used for the electrochemical

measurements. Manual rinse can be triggered by pushing button (5).

TPM870 7

1.2.2 Setting up the hydraulics circuit

We recommend you to place the Hach 2100AN IS turbidimeter onto the

TPM870 and the Titration workstation or Ion Analyser on the left or right

side of these two instruments. The waste and rinse water containers can

be placed on the floor. Have in mind that around 150 ml of rinse water

are required per sample analysis. According to the number of samples to

analyse, it could be interesting to take the rinse water directly from an

ion exchanging column output.

Recommended position and space required

The Sample Changer can be placed on the right or on the left of the

system defined above. Place the extension burette (ABU52 or ABU62)

beside the Titration workstation or Ion Analyser.

3. Setting up the TPM870/turbidity cell tubing, suction tubing and

TPM870/rinse bottle tubing

Check the presence and correct positioning of the 3 female couplers (b),

strainer tip (c), and turbidimeter suction tube (d). Set up PVC tubings (3)

(L = 3.25 m, ∅ = 3/5 mm), (4) (L = 3 m, ∅ = 4/6 mm) and (5)

(L = 3 m, ∅ = 3/5 mm) by locking couplers (a) of tubing (2) into couplers

(b) of the 3 relevant tubings.

4. Setting up the turbidity cell

Mount the end of tubing (4) (L = 3 m, ∅ = 4/6 mm) on the turbidity cell

"IN" input (6).

Set up the Y-shaped PVC tubing (7) (L = 50 cm, ∅ = 3/5 mm) between

the waste bottle and the 2 turbidity cell (6) "OUT" outputs.

Note:

Humidifying the tubing ends with water facilitates all these operations.

If required, adjust the configuration of your installation by cutting each

tubing to a suitable length.

Clean the cell following the procedures of the turbidimeter User's Manual.

1.4 Preparing the measurement

system

1.4.1 TPM870

Before switching on the TPM870, check on the rear panel that the

voltage selection switch setting (115 V or 230 V) corresponds to the

mains voltage.

Mains voltage = 230 V

Mains voltage = 115 V

Connect the TPM870 to the mains using the 3 lead connecting cord

supplied (see paragraph 1.3, cable 10).

Important:

The TPM870 must be connected to an earthed mains socket for

safety reasons.

The power supply connector on the rear panel must remain

accessible and close to the user (2 m maximum) so that you can

quickly disconnect the cables in case of emergency.

Switch on the TPM870 ("POWER ON" switch on the rear panel).

1.4.2 Hydraulics circuit

On delivery, the useful volume of a 120 ml beaker is pumped in around

35 seconds. Although not recommended, the pump flow rate can be

decreased by turning the "Pump speed" screw potentiometer (see figure).

Please note that the factory tuning corresponds to the upmost position of

the screw potentiometer.

A 15 second manual rinse can be triggered by pushing a button. The

duration of a manual rinse is set on instrument delivery using set no. 1 of

switches (see figure). This duration can be changed but this operation is

not recommended (description in Appendix B).

1.4.3 Turbidimeter

1. Calibrate the turbidimeter as described in its user's manual.

2. Calibrate the turbidimeter analogue output

First select the minimum and maximum values:

Minimum value: 0.0000 RMn

Press key SETUP of the turbidimeter, display Mode = 14 using the

EDIT keys then press ENTER. Move the decimal point to the right

place using the right arrow key. Press ENTER twice then press

SETUP.

Maximum value: 20.0 RMx

Press key SETUP of the turbidimeter, display Mode = 15 using the

EDIT keys then press ENTER. Display 20.0 using the right arrow

key, press ENTER twice then press SETUP.

Calibration of the turbidimeter analogue output:

The turbidimeter outputs 1000 mV full scale and the TPM870 multiply

by 2 this value. Therefore, the calibration is performed from the

TPM870 and the "Measure" method of the TIM8xx, TIM9xx or

IONxxx workstation used. Connect the instruments as shown on

paragraph 1.3 and switch them on. On the workstation, select the

"Measure" method, call the Electrode window and press 2 to install

the electrode. Back in the Electrode window, press 5 to display the

mV measurement. For more information, refer to the workstation

short form reminders, part no. D21T047, D21T070, D21M070 or

D21M076.

Adjusting the zero of the analogue output

Press key SETUP of the turbidimeter, display Mode = 16 using the

EDIT keys then press ENTER. Use the turbidimeter up and down

arrow keys in order to read a measured value of 0.0 ± 2.0 mV on

the workstation display. Then, press key ENTER to confirm and

SETUP to quit.

Adjusting the maximum value of the analogue output

Press key SETUP of the turbidimeter, display Mode = 17 using the

EDIT keys then press ENTER. Use the turbidimeter up and down

arrow keys in order to read a measured value of 2000 ± 2 mV on

the workstation display. Then, press key ENTER to confirm and

SETUP to quit.

2. Starting an application

The hydraulics circuit and the turbidity flow cell are installed. The

sample changer SAC950 is installed and fitted with the turntable and the

optional dynamic rinse module (if used). TitraMaster 85 is installed on

the PC.

1. Connect the instruments as shown on paragraph 1.3.

2. Connect the PC to the Titration Workstation or Ion Analyser: please

refer to the TitraMaster 85 Getting Started, part no. D21T052.

3. Switch on the instruments in the following order: Sample changer

SAC950, TPM870, Turbididity meter, workstation.

4. Start TitraMaster 85 on the PC.

5. In the User identification window, detect the workstation connected

to the PC (tick the Detect connected stations box and click OK).
