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!

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

9.1 Software overview

The CU 382 has four different views which can be selected by using [Right]- and [Left]-button. The default screen (i.e. after restart) is the Parameter screen.

Pressing [Back] button several times (depends on level of sub menu) will always get the user back to one of these screens

9.1.1 .Status screen

The first row shows the version of the software. In case problems make it necessary to contact our service department, the Status menu enables the operator to easily identify the software version (Version) and the serial number (Serial) of the actual device.

The third row (Waiting) shows the waiting time to the next action (start of measurement or start of cleaning). This interval can be set in menu Measurement settings (Meas. Settings…).

The last row (YYYY/MM/DD) shows current date and time. This can be set in menu.

9.1.2 Parameter screen

This is the default parameter screen. It shows two measured values at once. Besides the reading itself the parameter name (FCL) and the unit (mg/l) is displayed. The inverted font in the header displays the selected parameter which is marked with a triangle symbol. To scroll through the list of configured parameters use [Up]- and [Down] buttons. Up to 8 parameters can be configured and therefore displayed.

These displayed parameters can be:

– Sensor reading – Analog input – Digital input – Flow guard

Quick calibration

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.

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.

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.

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.

9.4.4 Output settings

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.

After confirming one additional rows will be available. Due to the fact that the controller output range is from 0 % to 100

%, mapping isn’t necessary. The only parameter which can be changed is the maximum of

pulses/min for 100 % output. To change the maximum of pulses/min (for 100 %-output) select

Pulses/min with [Up]- and [Down] buttons and by pressing [OK] button the pulses/min can be changed with [Up]-, [Down]-, [Left]and [Right] button. Pressing [OK] button will confirm the maximum of pulses/min.

PWM : [0 %] defines the parameter value for 0 %-output (0 pulses/min); [100 %] defines the parameter value for 100 %output (max. pulses/min). Period [s] defines the duration of one pulse for 100 % output. The highest duration is 100 s.

After confirming one additional rows will be available. Due to the fact that the controller output range is from 0 % to 100

10. Servicing the product

10.1 Cleaning

The following DID parts require periodical checks and cleaning, the interval depends on the particular water in which they are applied. It is suggested to initially check these components on a monthly basis, reducing the frequency if possible depending on the actual water composition.

10.1.1 Inlet strainer

The strainer includes a sieve that will collect coarse material and can foul. Therefore, a periodical check of the strainer is necessary. Cleaning of the sieve is recommended at the indicated monthly interval or when the flow through the station drops below the optimal flow, although all valves are set in the open position and the pump (if installed) if working as specified and inlet pressure is correct.

Cleaning can be performed after switching off the water flow through the station. Unscrew the cap from the strainer, take out the filter and rinse it with drinking water. Remove any coarse materials from the strainer housing. Then reinsert the sieve and attach the screw cap.

10.1.2 Flow detector

As the line strainer removes larger sediment from the influent water stream, it is not expected that the flow detector will require maintenance. However, the flow detector contains moveable internals that respond to the flow. These can be affected by

fouling. In case the flow detection does not respond to flow changes, it can be dismounted from the station and carefully rinsed with water and a soft brush.

10.1.3 Sensor

Refer to sensor documentation

10.1.4 Control unit CU 382

If necessary, clean all control unit CU 382 surfaces with a damp and clean cloth.

10.2 Functional check

A functional check might be required for one of the following reasons:

• Initial startup

• Routine functional check

• Suspicion of DID malfunction

• Modification of DID (e.g. integration of additional sensor or device)

• Change of measuring location

Depending on the application (water composition), the sensors connected and the environmental conditions a regular functional check (weekly to monthly) is recommended. The following table provide an overview of all the actions that have to be performed to check the DID. Regarding the functional check of the individual sensors, please refer to the sensor manual.
