4. Installing the product

4.1 Installation location

As the correct installation of the DID is an important prerequisite

for satisfactory operation the following checklist for the

installation can be used to ensure that all sources for potential

operational problems can be ruled out to the greatest possible

extent during the installation, allowing the DID to operate

properly.

• Easy accessibility (mounting, sampling, functional check,

demounting)

• Availability of sufficient space sensor, installation fitting,

control unit, etc.)

• No external interferences (i.e. no electric and electro-magnetic

interferences by leakage current, earth fault of pumps, electric

motors, high voltage currents, etc.)

• Best possible weather and splash water proof set-up

• The panel is to be protected from UV (direct sunlight) to avoid

premature aging of plastic components.

• Power supply for control unit (operational reliability, voltage,

power)

For environment limits of installed sensors please refer to the

sensor manual.

The DID is designed to operate with drinking water at pressures

up to 0.3 MPa (43 psi) and temperatures from 0 (non freezing) to

45 °C (32 to 113 °F). Enclosure class of CU 382 is IP65.

4.2 Installing of DID

All parts of the DID are mounted onto a flat panel (see section

7.3 Components). The complete DID can be mounted quickly and

easily with spacer (min. 10 mm) onto a flat wall. The mounting

holes for bolts or screws have been pre-drilled and are indicated

in the dimensional drawings. For the correct dimensions and

space required for mounting please refer to the figure in section

12.4 Dimensions.

For DID versions with tank immersed sensors the control unit

CU382 is mounted directly on the wall. The drilling scheme is

shown in section 12.4_dimensions.

4.3 Installing of hydraulic system

Sample water inlet and outlet have to be mounted onto the DID,

which will require the following actions, in the order presented

below:

• Remove the two blind bolts used for transport from the inlet

threat and the outlet threat of the flow cell using a 10 mm

hexagon socket screw key (see Fig. 1 below).

• Mount the specific fitting onto the outlet

• Mount the customer inlet tube onto the 1/2" inlet fitting

Fig. 1 Outlet fitting

WARNING

Danger of personal injury due to contact with

chemicals!

Wear the stipulated personal protective

equipment (protective clothing, goggles,

respirator etc.) when handling chemicals!

Observe the chemical manufacturer's safety data

sheets (MSDS) and safety instructions of the

used chemicals!

WARNING

Electric shock

• Switch off the power supply before connecting the

power supply cable and relay contacts!

• Do not dismantle the device!

• Maintenance and repair must only be carried out

by qualified personnel!

WARNING

Toxic material

Because the DID can be installed in industrial and

waste water applications, one has to take care during

mounting and demounting of the system, as parts of

the device can be contaminated with dangerous

chemicals or pathogenic germs. All necessary

precautions should be taken to prevent endangering

of one’s health during work with the measuring

device.

WARNING

Electric shock

• Switch off the power supply before installing!

Enclosure class IP65 is only guaranteed if the

terminal cover is correctly sealed, if the front

panel of the terminal enclosure is closed and the

appropriate cable glands or dummy caps fitted

TM06 5927 0316

English (GB)

Please note the pressure and flow limitation of the DID as

explained in the technical data on the warning label. Independent

of the inlet discharge the flow within the DID will be reduced by

the flow restrictor to the correct amount.

• Mount the customer outlet tube onto the 1/2" outlet fitting

• Ensure proper layout of the outlet tube to avoid soaking

The tubing on the outlet has to be designed in that way that a

draining of the flow cell is not possible. To ensure this a vented

outlet has to be used. Furthermore no shut-off valve should be

used to avoid back pressure within the flow cell.

• Install strain-relief in case of long / heavy outlet tubes to avoid

mechanical load of the flow cell.

• Due to sealing plugs on in- and outlet, proper 1/2" fittings have

to be mounted by the costumer (part of delivery).

• High loads due to heavy tubes on the outlet port of the flow

cell can damage the mounting of flow cell. Therefore it is

recommended to install a strain-relief for the outlet tubing.

4.4 Installing of sensors

All sensors used in the DID are packed separately to avoid any

damage. They have to be prepared before installation according

to the section Installation in the sensor manual. Within this

manual you will also find a detailed explanation how to mount the

sensors into the flow cell.

As soon as the sensors are ready for operation they should be

wetted all the time. All sensors equipped with electrolyte and

membrane cap have to be powered all the time.

4.5 Checking of tightness

Carefully open the inlet valve on the inlet and check for any

leakage of the DID. Check if any air bubbles are visible within the

tubes and spill them out by temporary increase of the discharge.

5. Starting up the product

5.1 Initial startup

Once the mounting and installation have been completed and

checked, the initial start up of the DID will require the following

actions, in the order presented below:

Described below are the steps that are specific for the DID and

that are not covered in the specific manuals of the sensors

included in your DID. The DID specific actions are to be

performed in the following order:

1. Connect all sensors to the control unit CU 382

2. Open inlet valve slowly

3. Check for leakage in the hydraulic system of the DID

5.2 Terminal connection

Once the cover has been opened (two cross head screws

removed) you have access to the cable terminal compartment of

the control unit CU 382.

Be aware that cable clamps of relay contacts you have connected

to the device might also have power supply (230 VAC),

depending on how they have been interconnected!

Fig. 2 Plan of terminal connections within control unit CU 382

WARNING

Electric shock

• Switch off the power supply before installing!

Enclosure class IP65 is only guaranteed if the

terminal cover is correctly sealed, if the front

panel of the terminal enclosure is closed and the

appropriate cable glands or dummy caps fitted.

• This type of work must be carried out by

authorized persons only and after disconnecting

the power supply!

5.3 Connection of sensors to the control unit CU 382

All sensors for the DID will be delivered with a plug connection on

the sensor itself. The connection cable C-1-010 has to be used to

connect the sensor to a compatible socket provided on the control

unit CU 382. Sensors for submersed installation are equipped

with a fixed cable already including the plug.

Before connecting the sensor, ensure that the sensor plug and

the connector on the control unit are dry and clean. Otherwise

communication errors and / or device damage might occur.

Connectors not in use should always be covered with the

protective cap.

5.4 Connection of valves for automatic cleaning

Valves, used for steering of the automatic sensor cleaning in case

of submersed installation, can be wired to the terminals 10

(Valve) and 11 (GND) to supply the valve with 12 VDC power (see

Fig. 2). In case a separate cleaning signal is used, this can be

wired to the terminal 12 (Clean In). This steering signal has to be

at least 5 V.

5.5 Connection of further in/outputs

For connecting actuator devices (e.g. dosing pumps or chlorine

regulators), please observe the relevant documentation.

5.6 Connection of power supply

The control unit CU 382 has to be connected to the appropriate

power supply. The connection of power supply (AC), has, without

fail, to include an earthed conductor wire (PE - "potential earth")!

The power supply earth (PE) is to be made properly. Process

medium (e.g. waste water) must be connected to the same earth

ground with less than 0.5 Ohm.

The power supply has to be equipped with an earth leakage

circuit breaker.

5.7 Starting up of operating software

Once the control unit CU 382 has been connected to the power

supply, it will show the s::can logo for 5 seconds while starting-up.

If the CU 382 internal settings have been reset to default, the CU

382 will start with the selection of the language (see section

9.2.8 Select language).

Subsequently, reading and information display will be shown. The

most recent information obtained by the CU 382 will be displayed,

even when no sensor is connected.

When no communication to an installed sensor is possible, only

those menus are available that are not concerning a sensor’s

settings (see section 9.2 General set up / status). In this case the

error relay will be in "error" mode. In case of such an error, an

entry to that effect is made in the logbook (see section 9.6 USB

menu / Data transfer).

5.8 Sensor initialisation

For operating the control unit CU 382 with one or several sensors

it is necessary to install (initialise) every single sensor on the CU

382. This can be done using the software supported initialization

process. During this process one sensor has to be connected to

the CU 382 and all other sensors are disconnected. Doing so an

individual address will be allocated to every sensor. The

corresponding address will be stored on the respective sensor.

Section 9.2.2 Manage parameters will guide you through this

task.

6. Storing and handling the product

The temperature and humidity limits for device storage, which are

described in the section Technical data, are to be observed at all

times. The device shall not be exposed to strong impacts,

mechanical loads or vibrations. The device should be kept free of

corrosive or organic solvent vapours, nuclear radiation as well as

strong electromagnetic radiation.

Damage to the sensor caused by wrong storage will not be

covered by warranty (please refer to the sensor manual).

Observe the permissible ambient conditions! See section

12. Technical data

WARNING

Electric shock

• Switch off the power supply before installing!

Enclosure class IP65 is only guaranteed if the

7. Product introduction

7.1 Intended use

The DID is designed for online monitoring of water quality and

controlling of disinfectants in clean media, such as drinking water.

The required components - sensors and control unit CU 382 - are

assembled with required flow cells, mounting fittings and

pipework on a compact panel.

In all types of applications, the respective acceptable limits, which

are provided in the technical data in the respective manuals, have

to be observed. All applications falling outside of these limits, and

which are not authorised by the manufacturer in written form, do

not fall under the manufacturer’s liability.

The device must only be used for the purpose described in this

manual. Use in applications not described in this manual, or

modification of the device without written agreement from the

manufacturer, is not allowed. The manufacturer is not liable for

claims following from such unauthorised use. In such a case, the

risks are the sole responsibility of the operator.

7.2 Functional principle

The control unit CU 382 is equipped with a display and can be

operated via 7 buttons on the front panel of the device. The

operating software starts automatically when the CU 382 is

powered on.

The CU 382 collects readings from all sensors using a digital bus

connection. It displays the data and makes it available for dosing

purpose. The CU 382 also includes a PID (Proportional-Integral-

Derivative) controller which is capable of dosing disinfectants to

the monitored water (drinking-, bathing-, waste-water, ...).

The hydraulic part of the station manages the complete water

flow from the inlet to the outlet of the DID. This includes filtration,

pressure reduction, flow restriction and flow control as well as

specific designed flow cells for proper mounting of the sensors

and appropriate sampling.

It is possible to make a quick calibration directly from the

parameter screen.

Choose the parameter you want to calibrate with [Up]- and

[Down] buttons and pressing [OK] button will open up the Quick

calibration menu.

Before taking a sample to perform a calibration, rinse the

sampling point of the flow cell at least 3 times to remove all

residuals from the sampling point. After this, approx. 10 ml should

be analysed by a reference method and the result has to be

entered into field Lab 1.

At the same time the sample is taken, Sample 1 has to be

selected with [Up]- and [Down] buttons and [OK] button has to be

pressed to measure the raw value of this sample. This current

measured raw value will be stored onto the sensor.

As soon as the Sample 1 is measured and the corresponding Lab

1 value has been entered, the calibration can be executed by

selecting Perform Calibration with [Up]- and [Down] buttons and

pressing [OK] button.

The Quick calibration menu will be closed and the new calibration

coefficient will be used for measurement.

9.3.1 Calibrate expert

Depending on the connected sensor several types of calibration

can be performed. If a local calibration cannot be performed to a

monitored parameter (e.g. actual operating software does not

support this feature) the CU 382 will display an user information.

Before calibrate be sure that the parameter value is stable!

Two different main types of calibration are available: Local or

Global.

By default Local is selected. This is the normal calibration

performed by the user during operation. The Global calibration is

used for factory calibration and therefore only performed by the

manufacture of the sensors.

With Mode three different local calibrations can be chosen:

Offset, Linear and Span. The availability of these modes depends

on the sensor type (see Table below and the manual s::can

sensors for further important information and details).

Performing an offset calibration

This type of calibration is an in-situ calibration. There is no need

to remove the sensor from the flow cell. Within the entry field

Mode the type Offset has to be selected.

Before taking a sample to perform a calibration, rinse the

sampling point of the flow cell at least 3 times to remove all

residuals from the sampling point. After this, approx. 10 ml should

be analysed by a reference method and the result has to be

entered into field Lab 1.

At the same time the sample is taken, Sample 1 has to be

selected with [Up]- and [Down] buttons and [OK] button has to be

pressed to measure the raw value of this sample. This current

measured raw value will be stored onto the sensor.

As soon as the Sample 1 is measured and the corresponding Lab

1 value has been entered, the calibration can be executed by

selecting Perform Calibration with [Up]- and [Down] buttons and

pressing [OK] button. Now Value will show the current calibrated

reading. Offset will show the calibration coefficient that is stored

onto the sensor.

Performing a linear calibration

For this type of calibration it is recommended to demount the

sensor from the flow cell and put it into a beaker glass with well

know standard solutions for Sample 1 and Sample 2. The values

Lab 1 and Lab 2 are taken from the standard solution labels.

Don’t forget to use temperature compensated values (i.e. pH

buffers depends on temperature)!

Between the two concentrations of Sample 1 and Sample 2 the

entire measuring range that can be expected at the location

should be covered to achieve the best possible calibration. Within

the entry field Mode the type Linear has to be selected.

It is recommended to measure the first raw value of the standard

solution 1 after the sensor is well conditioned to the standard

solution. Sample 1 has to be selected with [Up]- and [Down]

buttons and [OK] button has to be pressed. The first measured

raw value is stored onto the sensor.

Before measuring the second standard carefully rinse the sensor

with distilled water three times.

Submerse the sensor into the second sample, wait for

conditioning and measure the second raw value of the standard

solution 2. Sample 2 has to be selected with [Up]- and [Down]

buttons and [OK] button has to be pressed. The second

measured raw value is stored onto the sensor.

Selecting Perform Calibration with [Up]- and [Down] buttons and

pressing [OK] button will perform the calibration and Value will

show the current calibrated value. Offset and Slope will show the

calibration coefficients which are stored onto the sensor.

Performing a Span calibration

This type of calibration is an in-situ calibration. There is no need

to remove the sensor from the flow cell. Within the entry field

Mode the type Span has to be selected.

Before taking a sample to perform a calibration, rinse the

sampling point of the flow cell at least 3 times to remove all

residuals from the sampling point. After this, approx. 10 ml should

be analysed by a reference method and the result has to be

entered into field Lab 1.

At the same time the sample is taken, Sample 1 has to be

selected with [Up]- and [Down] buttons and [OK] button has to be

pressed to measure the raw value of this sample. The current

measured raw value will be stored onto the sensor.

As soon as Sample 1 is measured and the corresponding Lab 1

value has been entered, the calibration can be executed by

selecting Perform Calibration with [Up]- and [Down] buttons and

pressing [OK] button. Now Value will show the current calibrated

reading. Slope will show the calibration coefficient that is stored

onto the sensor.

9.3.2 Monitor

Due to the fact that the controller output range is from 0 % to 100

%, mapping isn’t necessary.

So, if 4/20 mA #1,2,3 (-> analog output) is selected controller

output is automatically mapped to analog 0/4-20 mA (4-20 mA ->

0-100 %).

If a digital output is selected, two different kinds of types can be

defined:

PULSE: [0 %] defines the parameter value for 0 %-output (0

pulses/min); [100 %] defines the parameter value for 100 %-

output (max. pulses/min). Pulses/min defines the maximum

number of pulses per minutes for 100 % output. The highest

number is 180.

To change the digital output to type PULSE select Type with [Up]-

and [Down] buttons and by pressing [OK] button the type can be

changed with [Up]-, [Down] button to PULSE. Pressing [OK]

button will confirm the type of digital output.

If one of the available parameters generates an alarm, the

behaviour of the controller can be defined for every parameter

alarm separately. If a parameter alarm is set, the controller stops

to dose if the chosen alarm occurs.

To change the behaviour of the controller select the desired

parameter with [Up]- and [Down] buttons and by pressing [OK]

button the parameter alarm can be changed with [Up]- and

[Down]- button. Pressing [OK] button will confirm the parameter
