2. Description of the equipment
2.1 ACTEON 5000 transmitter.
2.1.1 General description.
The ACTEON 5000 digital transmitter can be connected to two digital sensors in the PONSEL MESURE range to monitor the following parameters: pH, redox, temperature, dissolved oxygen (using optical technology), conductivity, salinity, turbidity (NTU, mg /L), Suspended Solid, Sludge blanket detection….
The values measured are displayed and transmitted using analog or digital technology. The preconfigured regulation functions can be used to optimize the control of processes.
The ACTEON 5000 is used in combination with a wide range of interference-resistant digital sensors, offering pre-amplification features built into the sensor and digital signal processing. All the data regarding the calibration, history, users and measurements is processed directly within the sensor, thus delivering very high levels of traceability and enhancing the reliability of the measurements.

2.2 Digital sensors.
The digital sensors in the PONSEL range are equipped with galvanic isolation and can perform digital signal processing to optimize the reliability of the measurements and data sent to the ACTEON 5000 terminal. All the data regarding the calibration, calibration history, users and measurements is processed directly within the sensor and transmitted via a Modbus RS-485 link.
The range of digital sensors can be used to measure a variety of parameters: temperature, dissolved oxygen, pH, redox potential, conductivity (4-electrode or inductive measurement principle), turbidity and suspended solids.
2.2.1 OPTOD sensor: dissolved oxygen (optical technology). The OPTOD dissolved oxygen sensor applies the luminescence-based optical measurement
technology and measures reliably and accurately without requiring calibration. With no consumables or maintenance required, the OPTOD sensor gives an immediate return on the investment. The only intervention required is to replace the DO disk every two years. Since it does not consume oxygen, the OPTOD sensor can be used in all media; even when there is a very weak flow of water. The body is made of passivated 316 L stainless steel or Titanium for applications in corrosive media.

2.2.2 PHEHT sensor: pH and temperature. This PONSEL sensor is fitted with an Ag/AgCl reference electrode, used to measure pH and redox, in
a "PLASTOGEL"® KCl-saturated plasticized electrolyte. The Plastogel® electrolyte is in direct contact with the external environment without interposition of capillary or porous material. There is therefore no risk of fouling or deactivating the reference electrode. The electrode used to measure the pH is a pH-sensitive glass bulb (made from special glass) welded to the end of a crystal tube, and the electrode for Redox measurements is a platinum disk.
Temperature: measured by an NTC thermistor inserted in a stainless steel sheath.

2.2.5 C4E sensor: 4-electrode conductivity. The operation of the sensor is based on 4-electrode conductivity technology: an alternating current at
constant voltage is set up between a pair of graphite primary electrodes. The secondary electrodes, made from platinum, adjust the drive potential at the primary electrodes to compensate for any fouling. The voltage measured between the primary electrodes varies depending on the resistance of the medium, and thus the conductivity.

3.2 Electrical connections.
3.2.1 Safety instructions – Installation. Isolate the power supply to the measuring device before performing any electrical connection work.
The electrical wiring and cabling work must be performed exclusively by authorized personnel.
Due to the risk of electrocution, systematically isolate the power supply to the controller before performing electrical connection work.
Warning for the model supplied with 10 – 30V
Risk of electrocution: do not connect a device operating in mains power mode to a model supplied with 10-30 V.
Risk of electrocution: the connection of a protective earth (PE) is compulsory when wiring and cabling both 100-240 Va.c. and 10-30 Vd.c. models.
Warning for wiring the relays
Fire risk. Since the relay contacts have a nominal value of 6 A, the external loads connected to the relays must be fitted with devices which limit the current to < 6 A.
Open the unit's lower cover to access the controller's wiring terminals. Unscrew the two screws which hold the lower protective cover. Before removing the cover, loosen all the cable glands so that the cables can slide in and out. Figure 3 shows the transmitter's wire connection zone when the lower protective cover is removed.

5.2 Installation of digital sensors.
When sensors are connected to the transmitter for the first time they must be installed by running a SCAN (to scan the addresses from 1 to 243).
As soon as the transmitter detects a sensor, it displays its address, its serial number (which is also engraved on the body of the sensor) and a description of the sensor.
In the example above, pH and oxygen sensors have been detected: the pH sensor is at address 24, the sensor's serial number is SN-PPHRA-0762 and the description of the sensor is pH/redox/Temperature Ponsel Mesure. The OPTOD sensor is at address 10, the serial number is SN­PODOA-4032 and its description is OPTOD/Temperature Ponsel Mesure.
The operator can stop the SCAN operation at any time by pressing on the icon. If no sensor is detected, or 2 sensors have the same address (an address conflict) or a communication
error is detected, then the device displays a warning message accompanied by the icon. Pressing on the icon accesses the addressing menu (refer to section 6.2.1 for more details
about the addressing function) where the operator can change the sensor's address in the event of an address conflict (i.e. if 2 sensors have the same address).
5.3 Selection of the parameters.
Once ACTEON has detected the sensors, the parameters measured by the sensors must be set up. For each sensor, a primary and a secondary parameter can be selected. To access the measurement settings menu, follow the sequence shown below from the home screen:

Icon
Functionality
Used to access the sensor's calibration menu
This menu is used to set up the external data used for compensation purposes
The external compensation data is detailed in the table below:
Set-up line
Functionality
Atmo. pressure
Atmospheric pressure compensation is applied to the OPTOD sensor (measurement of oxygen levels using optical technology). The atmospheric pressure sensor is built into the ACTEON 5000. The first line is used to activate the compensation and to access a second line which is used to adjust this parameter (possible values: 0 to 2,000 hPa).
Salinity
Salinity compensation can be applied to the Oxygen in mg/L parameter measured by the OPTOD oxygen sensor. The first line is used to activate the compensation and to access a second line which is used to adjust this parameter (possible values: 0 to 85.00 g/kg).
Temperature
Each sensor is equipped with its own temperature sensor, and the temperature recorded is considered if temperature compensation is required (for the pH, oxygen in mg/L and conductivity parameters). However, it is also possible to enter a fixed external compensation value. The first line is used to activate the compensation and to access a second line which is used to adjust this parameter (possible values: 0.00 to 40.00 °C).
Alpha
This coefficient can be set for the Non-compensated conductivity parameter measured by the CTZN sensor (possible values: 0.0 to 6.0 %/°C) in order to activate linear compensation.
To select the line above or below, or to increase or reduce a value, use the and icons.
The icon confirms the value set for the external compensation data. Any changes made become effective when the "Communication completed successfully" message appears.
To access the "Calibration settings" menu from the "Calibration: sensor 1 (or 2)" window, select the "Calibration" icon.

Detailed calibration log: this menu contains the data for the last ten calibrations (offset/gain) … The coefficients for a specific calibration can be reused.
The Calibration settings window lets the operator: select the parameter to be calibrated; enter the operator's name; select a calibration mode and set the values of the standards used.
Set-up line
Functionality
Parameter
The parameter to be calibrated can be selected from a drop-down menu which offers the parameters measured by the sensor.
Operator
This menu is used to enter the Operator's name (maximum of 13 characters) which will be saved with the results of a calibration process.
Type
This line appears if the parameter selected for calibration is oxygen as a %Sat. To complete this line, the operator can select either a 2-point calibration (OFFSET and GAIN) or a single-point calibration (GAIN only).
Mode
The options are: "Single" or "Multiple" mode: when several sensors of the same type are connected, a parameter common to all the sensors can be calibrated. The "Single" option is used when calibrating one parameter for one sensor, and "Multiple" is used when calibrating one parameter for 2 sensors (e.g. the Temperature parameter measured by all the sensors, or the connection of 2 pH sensors).
Standard 1
In the "Standard 1" window, which only appears if the value can be modified, the value of the Standard can be set using a number pad and will be used during the first step of the calibration for the calculation of the OFFSET. The value which can be set cannot exceed the minimum and maximum values.
29
Version 2.1 Update: April 2016
Standard 2
In the "Standard 2" window, which only appears if the value can be modified, the value of the Standard can be set using a number pad and will be used during the second step of the calibration for the calculation of the GAIN. The value which can be set cannot exceed the minimum and maximum values.
Site
If a NTU sensor or a MES sensor is connected to the device and when selecting a calibration in mg/L or in g/L, the calibration process will be saved in a file saved under the name of the site. Up to 10 sites can be configured, each identified using 8 characters.
Pressing on the icon validates the setting of the calibration data and starts the first calibration step ("Standard 1" window).
In the window corresponding to the first step in the calibration, the first line indicates the value of the N1 standard and the second line presents the measurement delivered by the sensor in contact with the standard solution. A message indicates if the value measured by the sensor is stable or not. The confirmation of the first calibration step (gearwheel icon) initiates the second step ("Standard 2" window). Once the second calibration step has been confirmed, a summary window appears which presents the information about the values of the standards used and the coefficients calculated.
The appearance of the icon on a coefficient calculation line indicates that the coefficient has been confirmed, whereas the icon indicates that the coefficient obtained is out-of-range.

7. Maintenance
7.1 Maintaining the transmitter:
Isolate the power to the measuring device when performing maintenance work.
Maintenance work must exclusively be carried out by authorized personnel.
Due to the risk of electrocution, disconnect the controller from the power supply systematically when performing maintenance work on the transmitter.
Do not use a corrosive or inflammable solvent to clean the transmitter. The use of this type of solvent could damage the device (its screen) and may invalidate the warranty.
After checking that the ACTEON 5000's protective covers are properly closed, wipe the outside of the transmitter with a soft cloth dampened with a mixture of water and non-corrosive detergent.
Replacing the lithium battery:
The lithium battery cannot be replaced by the operator; contact the after-sales service.
46
Version 2.1 Update: April 2016
7.2 Maintenance of digital sensors:
7.2.1 OPTOD sensor.
General description
Oxygen: luminescent membrane sensitive to the oxygen level in the medium
being analyzed. Gaseous exchange between the membrane’s material and
the medium. Temperature: NTC thermistor.
Materials
316L stainless steel version: polyamide, silicone and quartz; polyurethane sleeve around cable. Titanium version: polyamide, silicone and quartz; polyurethane sleeve around cable.
Precautions
The membrane is sensitive to:
- chemicals (organic solvents, acids, hydrogen peroxide),
- mechanical stresses (impacts, abrasion, tearing).
Measurement/Interference
When measuring, check that bubbles do not become trapped under the membrane.
If chlorine is present, the quality of the measurement will be impaired (overestimate of the level of dissolved oxygen). When immersing the sensor in the medium to be measured, wait until the sensor's temperature has stabilized before taking the reading. To optimize the service life of the sensor, we recommend a measurement interval (refresh rate) of more than 5 seconds.
Operating temperature
0 °C to 50 °C Temperature compensation effective over the range 0-40 °C
Servicing
After each use, rinse the sensor and the membrane carefully in clean water. If deposits such as biofilm or sludge persist, wipe the membrane carefully with a soft cloth or absorbent paper.
Caution: for the titanium version, clean the body of the sensor with acetone (do not use methylated spirits, ethanol or methanol).
Caution: only unscrew the sieve cap containing the DODISK when replacing the disk. If the sieve cap has to be replaced, screw the new sieve cap on slowly to allow the air to escape slowly.
Storage
Keep the membrane hydrated using the protective bag and a dampened absorbent wad of material (e.g. cotton wool. After being stored in dry conditions, rehydrate the membrane for 12 hours by immersing the sensor in water.
Storage temperature
- 10 °C to + 60 °C
Oxygen calibration
Using a clean sensor, occasionally check the 0% Sat value by immersing the sensor in a sulfite solution in water (sulfite concentration <2%). If there is a zero error, perform a complete calibration of the sensor.
Caution: do not allow the sensor to remain in contact with the sulfite solution for more than 1 hour.
The 2-point calibration is performed using a sulfite solution (for the offset)
then, after rinsing and drying, the sensor’s gain is determined by exposing the
sensor to moisture-saturated air (or to clean water saturated with air).
Temperature calibration
The calibration of the temperature sensor is a 2-step process:
- step 1 (offset): the sensor is placed in a container containing a water bath and ice,
47
Version 2.1 Update: April 2016
- step 2 (gain): the sensor is placed in a medium (with an even temperature distribution in the medium) at a known temperature. This temperature may be measured using a certified thermometer.
48
Version 2.1 Update: April 2016
7.2.2 NTU sensor: Turbidity.
General description
Turbidity: nephelometric measurement by IR diffusion (wavelength: 880 nm) at 90°. Temperature: NTC thermistor.
Materials
PVC, PMMA, Polyamide, POM-C, polyurethane sleeve on cable
Precautions
The optical windows are sensitive to:
- chemicals (organic solvents, strong acids and bases, hydrogen peroxide, hydrocarbons),
- mechanical stresses (impacts, abrasion).
Measurement/Interference
When in use, the sensor must not come into contact with the sides or bottom of a container. Maintain a minimum distance of 2 or 3 cm between the sides and the sensor (depending on the concentration of the medium).
Bubbles on the optical components can interfere with the measurements. When immersing the sensor in the medium to be measured, wait until the sensor's temperature has stabilized before taking the reading. If measurements are being made in a range between 0 and 20 NTU, or if the sensor saturates (a value of 9999), it is advisable to use the protective sieve to avoid interference from edge effects, sunlight, etc.
Operating temperature
0 °C to 50 °C
Servicing
After each use, rinse the sensor carefully in clean water. If deposits such as biofilm or sludge persist, clean the sensor carefully with soapy water and wipe the head with a soft cloth or absorbent paper.
Storage
Place the protective bag over the head of the sensor to prevent the optical part from being scratched.
Storage temperature
- 10 °C to + 60 °C
Turbidity calibration (in NTU)
The NTU sensor is an optical sensor which requires very little calibration. Using a clean sensor, occasionally check the 0 NTU value by immersing the sensor in clean, bubble-free water. If there is a zero error, perform a complete calibration of the sensor (over 1 or 4 measurement ranges).
This procedure requires a formazine solution whose concentration lies at the mid-point of the measurement range being calibrated. This solution is prepared from a 4,000-NTU stock solution.
Use a 200 ml volumetric flask when preparing the solutions. Add the required volume of formazine (refer to the table below) and make up to 200 ml with distilled water.
Formazine solutions with concentrations of less than 1,000 NTU degrade fairly quickly; do not keep the solution for more than a few days. The 2,000 NTU solution can be kept for 2 to 3 weeks in a fridge in an opaque bottle.
Measurement range

Version 2.1 Update: April 2016
Turbidity calibration (in mg/L)
When a turbidity sensor is used to measure in a range whose units are mg/L, then the sensor must be calibrated using a field sample.
A 2-point calibration is performed:
- 1 offset using distilled water (0 mg/L),
- 1 gain using a sludge sample: immerse the sensor in the sample, with stirring, and log the theoretical value measured by the sensor. Using the same sample, analyze the dry weight in a laboratory in accordance with standard EN 872 within a range from 0-500 mg/L, and in accordance with standard NF T 90 105 2 if the concentration is > 500 mg/L.

7.2.7 VB5 – MES 5 sensor: Sludge blanket detection – Sludge blanket detection/Suspended Solid/Turbidity.
Description
Optical IR (870 nm) based on IR absorption Temperature: NTC.
Materials
DELRIN, Nickel-plated brass, EPDM ; Polyurethane jacketed cable
Safeway
The optical windows are vulnerable to: chemicals (organic solvents, acids and strong bases, peroxide, hydrocarbons), mechanical treatments (impact, abrasion).
Measure/ Interfering
Bubbles on optical parts can interfere with the measurement. On environment change, wait sensor’s temperature stabilization before proceeding with measurement.
Operating temperature
0°C to 50°C
Maintenance
After each use, rinse meticulously the sensor with clear water. If deposits like biofilm or mud persist, clean the sensor with soapy water and wipe the head with a soft cloth or an absorbent paper.
Storage
Place the protection case on the head of the sensor with a bottom of water to maintain the hydrated optical windows.
Temperature of storage
- 10°C to + 60°C
Turbidity calibration in FAU
On a clean sensor, check once in a while the 0 NTU value by dipping sensor in bubble free clear water. If the 0 point is shifted, proceed with the complete sensor calibration (on 1 or 4 ranges).
For this procedure, a Formazin solution, with concentration matching the middle of the measurement range, will be necessary. This solution will be prepared from a 4000 NTU main solution.
For the preparation of solutions, take a flask of 200 mL. Introduce the necessary volume of Formazin (cf. table below) and fill up to 200 mL with distilled water. The formazin solutions of concentrations lower at 1000 NTU deteriorate quickly, so do not preserve a solution during several days. The solution at 2000 NTU can be preserve in the refrigerator for 2 or 3 weeks in a opaque flask.

Suspended Solid calibration in g/L
Turbidity in g / L, it is necessary to calibrate the sensor on a real sample. The calibration is achieved in 2 steps :
- Step 1 (offset) : immerse the sensor in distilled water (0 mg / L),
- Step 2 (slope) : immerse the sensor into a sample of sludge, maintained under agitation, and validate the theoretical value measured by the sensor. Analysis the sample dry weight in the laboratory according to the NF standard T 90 105 2.
Sludge blanket detection in %
For a use of the sensor in mode Sludge Blanket detection the sensor is tested on 1 point:
- 1 offset with some distilled water (100 %)
