1.7 INFORMATION ON RECYCLING AND USE OF MATERIALS

CHEMITEC, in accordance with specific European regulations, aims at constant improvement of development and of production procedures of its equipment with the objective of drastically reducing the negative impact on the environment caused by parts, components, consumption materials, packaging and the equipment itself at the end of its life cycle.

Packaging is conceived and produced to allow for its re-use or recovery, including recycling of the majority of the materials and to reduce the amount of waste or residues to be disposed of, to a very minimum. In order to assure a correct environmental impact the equipment has been designed with the smallest circuit possible, with the lowest differentiation possible of materials and components, with a selection of substances that guarantee utmost recycling and maximum reuse of the parts and waste disposal free from ecological risks.

The equipment is made in such a way as to guarantee the easy separation or dismantling of the materials containing contaminants compared with others, in particular during maintenance operations and the replacement of parts.

CAUTION

The disposal/recycling of packaging, of consumption materials and of the equipment itself at the end of its life cycle must be carried out in accordance with the norms and regulations that are currently valid in the country in which the equipment is used.

2.1 MEASURING PRINCIPLES

The electrical conductivity measure shows the ion concentration into a solution. More is the solution acid or even basic salt quantity, higher is the conductivity. The conductivity

measuring unit is Siemens/cm. The measuring scale for water solutions starts with the ultra-pure water whose conductivity is 0.05 µS/cm (25°C). Conductivity of the natural water, e.g. of the drinking water, or of the surface waters is of about 100 ... 1000 µS/cm. Some bases, as the potassium hydroxide, with values being slightly higher than 1000 ms/cm, reach the scale upper value.

In particular, the conductivity measuring is used in water analysis (drinking water, mineral water, underground water, distilled water, demineralised water, boiler feed water, waste water), for galvanic baths controls, purity controls (organics, nutrients), in the thermoelectric units (steamcondensate cycle control), in the food industries, in sugar factories, cellars, textile industry, automatic irrigation plants, etc.

The electrical conductivity of a solution is defined as the reciprocal of the opposite resistance by a cubic centimetre of such a solution, at a certain temperature, i.e. of the resistance being measured between two 1 cm

Taking the 20°C temperature as a reference, the conductivity changes as per the following formula

surface electrodes, 1 cm. away, immersed in the above solution.

Page 11

DISSOLVED CONDUCTIVITY AND TEMPERATURE ANALYZER

4222

TECHNICAL MANUAL P/N XXX-0000 Rev.1 Ver.2.2

Ct = C20 [1 + α/

(T - 20)]

100

where: Ct = conductivity to the temperature T C20 = conductivity at 20°C T = solution temperature

α = T coefficient at 20°C in % / °C

The α value is between 1.3 and 3.1%/°C for almost all of the electrodes and is usually 2%/°C in the diluted solutions. Aiming at comparing the various solutions conductivity values, it is necessary to bring all the measure back to the 20°C reference temperature using the above said formula (take note that if the conductivity meter does not include the temperature equalizer, the measure refers to the solution conductivity at the effective temperature; if the conductivity meter includes the equalizer, the conductivity shown refers to that of the solution when brought to the selected reference temperature, nevertheless the solution temperature at the measuring time). The conductivity measure can be taken using both the electronic instrument and a measuring cell. The cell includes two ore more electrodes. The base electrical feature of the conducimetric cells is the “cell factor” (K) depending exclusively on the geometric dimensions of the cell and expressed in cm (cm2 of section divided by the “cell factor”. The conductivity value is given by:

Cs = C  K = C/F [2]

where: C

= solution specific conductivity C = conductivity reading on the instrument K = cell constant, in cm-1 F = cell factor, in cm

For measuring the low conductivity values it is recommended to use high factor cells and viceversa. Another important distinction standard relates to the materials of the electrodes, i.e.:

 platinum-plated (Pt spongy surface)

 stainless steel (properly satin and oil free surface)

 graphite

The concentric (or self-shielded) cells are then distinguished from the symmetrical electrodes. The measure accuracy and stability might be highly reduced by the electrode polarization and contamination. The polarization effect is due to the electrostatic charges that generates on the electrode surfaces (even if the ion movement is due to an alternate electric field) and is particularly detected under concentrate solutions; on the contrary, the contaminations are due to deposits, encrustations, oil, grease, etc. The two phenomena can be (partially) reduced by using electrodes made of a material suitable to the solution and by using a proper frequency of the oscillator powering the cell.

The locking of the control unit to the panel is made through the mounting backplate, which is fixed to the panel on the inner side, using the apposite screws.

3.1.4 CONNECTIONS TO THE POWER SUPPLY

If possible avoid any cables destined for high power use to be positioned close to the device as they may cause faults of an inductive nature to the analogical section of the instrument.

Apply a tension alternating between 100Vac and 240Vac 50/60 Hz or, according to details on the identification plate, the most stabilised tension possible.

Avoid at all costs connections to power supplies that have been rebuilt, for example, with the help of transformers in which this rebuilt power supply will feed other systems beyond the device (perhaps of an inductive kind) because, in this way, high tension spikes will be created and once they are irradiated it becomes very difficult to block and/or eliminate them.

CAUTION

The electric line must be fitted with a suitable life-saving device and magneto-thermal, in compliance with correct installation norms.

In any case it is always best to check the quality of the Ground connection. It is very common to

User

find Ground connections, mainly in industrial environments, that are generators themselves of disturbances: in the case of any doubts on quality a connection to a rod dedicated to the device plant is recommended.

3.1.4.1 Electrical Connections to the dosage systems (Users)

CAUTION

Before starting connections between the Device and the external Users, make sure that the electrical panel is switched off and the cables from the Users are not under tension.

“Users” mean the outlets and relays used in the device

− (SET1) for the Dosage Pump or control command

− (SET2) for the Dosage Pump or control command

− (ALARM) the alarm command transmitted by the instrument to the siren and/or flashing

light

− (WASH) electrode washing command

CAUTION

Each relay contact can support, on a resistive load, a maximum current of 1 Ampere with a max. of 230V, therefore a total power of 230VA

In the case of higher levels of power it is best to carry out connections as indicated in the layout of fig. 9-b)

If the load to be handed is of low power or of a resistive nature, the layout indicated in Fig. 9-a) can be used.

Loads lower then 230VA Loads higher then 230VA

A2) Setup System

In this part of the programme which is divided up into 5 functions, the basic functioning parameters of the instrument are set.

Description of the functions:

DATE/HOUR SYSTEM

Setting of the DATE and TIME of the system that will be memorised every time that figures are viewed in a historical perspective.

COMMUNICATION

The instrument has a serial port in RS485 which is separated galvanically and can be used for dialogue with a HOST system using the standard protocol MOD BUS RTU. Through the serial port it is possible to visualise the real time status, programme all of the Set-Up and downloading all of the archives of the instrument.

The Communication Set-up function is used to programme the serial port and is divided up into two settings:

ID Instrument: A numerical address from 1 to 99 to which the instrument will reply. The default is

01. Baud Rate: Speed of the RS485 serial which can be programmed at between 1200 and 38400. The

default is 9600.

LANGUAGE

It is possible to select the language used by the Software between: Italian, English, French, Spanish and German.

PASSWORD

At this stage it is possible to activate and programme for access to the instrument. Once activated, each time that the programming stage is accessed the access password will be requested.

The password is made up of a 4 figure number. The default is 2002 which will always remain active even if a new password is programmed.

In order to access the step “Password Status” or “New Password”, the existing password must be inserted and then the new input can be carried out.

DISPLAY

Contrast: It allows for the definition of a greater or lower contrast of the display according to the temperature in which the instrument is operating.

Background illumination: At this stage you can decide whether or not to maintain background illumination or to switch it off one minute after having released the key.

By programming YES the background illumination stays on, by programming ON it switches off automatically. NO is programmed as a default.

SERIAL NUMBER

In this part of the programme the serial number of the instrument is shown.

E1) Threshold

By programming the Set Point for this function, we can activate the relay as a Threshold by programming an ON value (relay activation) and an OFF value (relay deactivation). The free programming of these two values will allow for the creation of a hysteresis suitable for any kind of application.

By programming the ON value higher than the OFF one (fig. 15.a) an UPWARD threshold will be achieved: (When the value exceeds the ON value, the relay is activated and remains active until the value falls below the OFF value).

By programming the OFF value higher than the ON one (fig. 15.b) a DOWNWARD threshold will be achieved: (When the value falls below the ON value, the relay is activated and remains active until the value exceeds the OFF value). See fig.15.

Measure

Figure 15 – Threshold operation

Furthermore by acting on the Time ON and Time OFF parameters it is possible to define a DELAY time or a TIMED operation of the Relay during its activation.

Negative of positive ON and OFF Times can be defined. (fig. 16) By programming Negative Times the DELAY function is activated: Eg. Time ON: –5sec , Time OFF -10sec. (fig. 16.a) When the threshold is activated, the relay will close after 5 seconds (ON time) and it will remain

closet for the entire period in which the threshold is active. When the threshold is deactivated the relay will remain closed for another 10 seconds (OFF time) after which time it will open.

By programming Positive Times the TIME function will be activated: Eg. Time ON: 5sec , Time OFF 10sec. (fig. 16.b) When the threshold is activated the relay will alternate between an open/closed position according

to the times programmed. In the case of the example the relay will close for 5 seconds (ON time) after which time it will remain open for 10sec (OFF time). This cycle will continue until Threshold 1 is not deactivated.

E2) PID-PWM

By defining the Set Point as PID-PWM, through Relay 1, it is possible to activate a pump with an ON/OFF command almost as if it had a proportional adjustment. For this function the time period must be programmed (in seconds) within which the calculation of the PWM adjustment will come about. The maximum time that can be programmed is 999 seconds with a 1 second step. We recommend starting with short periods of time and increasing them gradually in order to avoid drastic variations in measuring. For operation of the Relay in a PID-PWM function see fig. 17.b.

Measure

4222

E3) PID-Frequency

By setting the Set Point as PID-Frequency it is possible, through Relay 1, to control a pump directly with impulse inputs. The maximum number is 7200 imp/h with steps of 200. The ON and OFF impulse time is fixed at 250mSec. For operation of the Relay in a PID-Frequency see fig. 17.a.

NOTE

Functions E2) and E3) are related to the programming of the PID parameters to be found in the menu 2.31 (Par. 4.3.8). Therefore, before programming this function we recommend that you check the programming of the PID parameters.

F1) Set Point2

The programming parameters of Set Point 2 determine the functioning logic of Relay 2. This Relay may only be programmed as a Threshold. Programming of threshold 2 is identical to the

one described for Threshold 1.

F2) Logical Set

The parameters of the Logical Set determine the functioning of the Alarm Relay. This function is deactivated by default.

This function activates an alarm when the measuring values are located outside of a specific “window”. It is, in reality, possible to programme a minimum value and a maximum value and once they are exceeded the instrument will generate an alarm. This function will allow an alarm to be activated if the measure values are over a certain “range”. In fact, it is possible to program a minimum and a maximum value: when exceeded, the equipment will generate an alarm.

This Logical Set is useful to control any possible faults to the system, eg. Defects in the dosage pumps etc.

F3) Alarm/Set Temp. 1

With this function the basic settings of the Alarm Relay are defined, all of which are handled by the anomaly conditions inside and outside of the instrument.

Considering the importance of this Relay, we recommend that it is connected to a visual and acoustic signal which should always be kept under control by personnel in charge of running the plant, in order to intervene immediately in the case of a signal.

Programming of the Alarm Relay is articulated into 6 functions, therefore allowing for external anomalies (measuring electrode and dosage systems) as well as internal anomalies to be kept under control. Description of the functions:

RELAY ABILITATION

Within this function, it is possibile to assign the relay. Setting “YES” means that the relay works as an alarm. Setting “NO”, the relay is automatically

assigned as temperature.

Page 36

CONDUCTIVITY AND TEMPERATURE ANALYZER

4222

TECHNICAL MANUAL P/N XXX-0000 Rev.1 Ver.2.2

SET RELEASE

With this function it is possible to deactivate or activate dosages in the case of an alarm. By programming YES, when any kind of alarm is activated, the Relay 1 and 2 contacts will open up

immediately and the analogical outlets 1 and 2 will be cancelled. By programming NO, even in the case of activation of the alarm, the Relay contacts and the

analogical outlets will not change their position. YES is set as a default.

RELAY LOGICS

The Alarm relay is an ON/OFF alarm and with this function it is possible to programme its opening/closing logic. CLOSED is set as a default.

By setting “CLOSED”, the Alarm relay will be opened in normal working conditions and will close in the event of an alarm.

By setting “OPEN” it will work in exactly the opposite way. The Alarm relay will close in normal working conditions and will open in the event of an alarm.

Furthermore, by setting OPEN it is also possible to control the anomaly of the absence of power tension which will lead to the immediate opening of the relay.

TIME OUT

With this function it is possible to set a maximum activation time of Set Point 1 and 2 after which time the alarm will be activated. This allows for the state of the dosage pumps to be kept under

control. By default this function is deactivated (time 00:00.00). The maximum time that can be programmed

is 60 minutes, at steps of 15 seconds.

PERMANENCE FIELD – PERMANENCE TIME

This function allows for the state of functioning of the measuring probe to be kept under control. If the measurement is stabilised within a certain interval for a period of time that exceeds the time

set, the instrument will generate an alarm. In order to activate this function, the following must be set: in the “PERMANENCE FIELD” step the minimum oscillation interval of measuring (delta

CONDUCTIVITY) in the “PERMANENCE TIME” the maximum time in which excursion must come about. If, during the period of time programmed, measuring is always within the interval programmed, the

instrument will set off an alarm. By default this function is deactivated as a delta 0 and a time of 00:00:00 has been programmed.

The maximum time that can be programmed is 99 hours at steps of 15 minutes.

F4) Wash/Set Temp. 2

The instrument is fitted with a Washing Relay that can control a solenoid valve for washing of the measuring electrode.

The washing stage lasts 1 minute altogether and it includes 15 seconds for control of the solenoid valve (closing of the washing relay) and 45 seconds for stabilisation of the probe.

RELAY ABILITATION

Within this function, it is possibile to assign the relay. Setting “YES” means that the relay works as wash. Setting “NO”, the relay is automatically

assigned as temperature.

Immediately before it starts, the instrument memorizes the values of the measurements, the state of Relay 1 and 2 and the values of the analogical outlets and it keeps them “frozen” for the entire duration of the washing cycle.

This situation is highlighted on the display using an hourglass and, furthermore, instead of the measuring value a counter appears indicating how many seconds are left until the washing stage is completed.

By default this function is deactivated as a time of 00 hours and 00 minutes is programmed. The maximum interval that can be programmed is 24 hours at steps of 15 minutes.

DURATION

Within this function it is possibile to set the duration (in seconds) of the washing period.

STABILIZATION

Within this function it is possibile to set the time (in seconds) needed to the stabilize the wash.

The instrument is fitted with two analogical outlets in a current that is separated galvanically and are independent of each other. The first outlet refers to the primary measuring therefore proportional to the Conductivity measured. The second, however, can be programmed between Temperature or CONDUCTIVITY.

H1) Measuring

In this step of the programme 4 functions can be set:

OUTPUT RANGE:

A selection can be made between 0-20mA or 4-20mA. The default is programmed at 0-20mA

LOWER LIMIT:

A Conductivity value at 0 to 4mA of output current can be set. The default is set at 0mS

UPPER LIMIT:

A Conductivity value of 20mA can be set for output current. The default is set at 20.0mS. The regulation of Lower and Upper Limit functions allow for the scale of analogical outputs to be

amplified. Furthermore, the output can be inverted to 20-0mA o 20-4mA

NAMUR OUTPUT:

This function is only activated if chosen as an Outlet Range of 4-20mA. If this function is activated in the case of an alarm, the outward value of the current will be 2.4mA according to the NAMUR standard. The default of this function is deactivated.

H2) Second Output

Page 39

The second output can be set as Temperature, Auxiliary or PID.

Algor.

If set as Temperature a Range between 0-20mA or 4-20mA can be chosen, the Lower and Upper limits of the Temperature value. For a detailed description of how to set them, refer to point 5.1 Measuring of Analogical Outlet. The default Range is 0-20mA, the Lower Limit is –30°C and the Upper Limit is +140°C.

If set as Auxiliary on the second output also, the conductivity measurement is repeated. But the Range of between 0-20mA or 4-20mA, the Lower limit and the Upper limit of the conductivity values can be chosen, different to the previous ones. For a detailed description of how to set them refer to point 5.1 Measuring of Analogical Outlet. The default Range is 0-20mA, the Lower Limit is 0mS and Upper Limit is 20.0mS.

If set as PID the Output range of between 0-20mA or 4-20mA must be set. For settings of the PID see part C3.

I1) Setup PID

In this step of the programme, the programming of parameters for PID functioning is carried out. The outlet of PID adjustment is analogical as well as digital and they can both be activated at the same time. The PID outlets are: Analogical Outlet 2 and Relay 1.

The PID function allows for all of the swings due to ON/OFF dosages to be eliminated. Furthermore, it allows for the threshold desired to be maintained and reached with extreme precision. The PID adjustment is a complicated adjustment that must take into account all system variables. This PID has been designed for those general applications with a fast retroactivity of the system. In reality, the maximum integral and derived times are 5 minutes.

The PID function allows for three adjustments to handle the dose. The PROPORTIONAL (P) Adjustment allows for the outward dimension to be more or less

amplified. The DERIVATIVE (D) function allows for our system to become more or less reactive to variations

of the sizes measured. The INTEGRATIVE (I) function allows for the swings to be regulated due to the derivative part.

Description of functions:

SET POINT

The value of the PID threshold that we want to maintain stable.

PID SETUP

ALGORITHM The kinds of algorithms handled by the instrument are: P = Proportional ; PI = Proportional –

Integral and PID = Proportional – Integral – Derivative

Page 40

CONDUCTIVITY AND TEMPERATURE ANALYZER

4222

TECHNICAL MANUAL P/N XXX-0000 Rev.1 Ver.2.2

The type of algorithm will be chosen according to the application requested. The P regulation will be set as a default.

THE ALGORITHM SIGN In this function the PID sign is programmed. If we programme DIRECT it means that as the

value measured is increased compared with the threshold defined, the PID value will decrease. However, if we programme OPPOSITE, as the value measured increases compared with the threshold defined, the PID value will increase. DIRECT is set as a default.

PROPORTIONAL The Proportional Range of the PID regulation compared with the bottom of the scale for the

instrument. Eg. For a conductivity with a range of 0-20mS, if a 100% Proportional is programmed it

means having a range of ±20mS of regulation compared with the threshold set. Therefore the value of the proportional is inversely proportional to the outlet, that is to say as the percentage of the proportional is increase the effects on the outlet decrease. Regulation of the proportional may vary between 1 and 500% in steps of 1%. The default is set at 100%.

DERIVATIVE TIME The Derivative part is set. The more the programmed time increases, the more the system will

be ready for variations to the measurement. The derivative time can be programmed between 0 and 5 minutes at steps of 5 seconds. The default is programmed at 0 minutes.

INTEGRAL TIME The Integrative part is set. The more the programmed time increases, the more the system will

mediate with the measuring swings. The derivative time can be programmed between 0 and 5 minutes at steps of 5 seconds. The default is programmed at 1 minute.

4.3.9 CALIBRATIONS MENU

This programme phase allows for the instrument calibration with the electrode used. Calibration must be carried out:

− When starting the measure instrument / electrode chain the first time

− Every time the electrode is replaced

− When starting the instrument after a long inactivity period

− In the case of any discrepancies compared with the known value

For granting a proper working, further to the above mentioned conditions, it will be required to check the calibration of or to recalibrate the instrument periodically.

User will determine the frequency of this operation, keeping into account the application and the electrode use.

We remind you that before carrying out any checks or recalibrations, the electrode must be cleaned thoroughly with clean water, making it stabilizing for at least 30 minutes on the atmosphere or into the known title solution.

known title and different concentrations can be used and inserted by pressing the UP and DOWN keys.

The calibration solution can be selected referring to the working range where the probe will

work in. Example: If the working range is between 500 and 1000µS, use a solution at approx. 750-800µS as second point.

Once finished the second point calibration, the instrument will check the calibration data compliance. If correct, the instrument will display “Calibration OK”; if not “Faulty probe”.

If ”Faulty Probe” is displayed, we recommend:

− To check the physical probe integrity.

− To check the cable integrity, the correct connection to the instrument and on the probe.

4.3.10 ARCHIVE MENU

The instrument is fitted with a Data Logger that allows for 16,000 records to be stored. Each record contains: the date, the time and the Conductivity value, the temperature value, the value of the Threshold 1 and 2, the state of the Relays 1 and 2 and the state of the Alarm Relay. The archive must be of a Circular kind, therefore once filled the next data will overwrite the oldest one and so on until it is completely FILLED, that is to say once it is filled storage is blocked and the full archive icon will appear.
