ment) The VisiPro DO Ex sensor is certified for use in explosive atmosphere. If these sensors are used in explosive atmospheres, the instructions in the chapter 3.3 must be followed. If the sensor is used in contact with gaseous or liquid organic solvents, the resulting measurement accuracy in this application must be separately checked and validated by the customer. ATTENTION! The VisiPro dO Ex sensor has a built-in temperature sensor (NTC 22k). This temperature sensor is to be used only for monitoring the sensor conditions, not for controlling the process temperature. ATTENTION! The measurement values transmitted over wireless communication are not intended to be used for process control. 1.2 About this Operating Instruction These Operating Instructions are designed to support the integration, operation and qualification of the VisiPro DO Ex and VisiPro DO (non Ex) sensors. To achieve this, it will describe the features of VisiPro DO Ex and its integration in Process Control Systems (PCS). Both the hardware and the communication between the VisiPro DO Ex and Process Control Systems are detailed in this manual. After reading this manual the user should be capable of installing and operating VisiPro DO Ex sensors. ATTENTION! Essential information for avoiding personal injury or damage to equipment. NOTE: Important instructions or interesting information. 2 Liability The liability of Hamilton Bonaduz AG is detailed in the document General Terms and Conditions of Sale and Delivery. Hamilton is expressly not liable for direct or indirect losses arising from use of the sensors. It must in particular be insured in this con-

junction that malfunctions can occur on account of the inherently limited useful life of sensors contingent upon their relevant applica-

tions. The user is responsible for the calibration, maintenance and regular replacement of the sensors. In the case of critical sensor ap-

plications, Hamilton recommends using back-up measuring points in order to avoid consequential damages. The user is responsible for taking suitable precautions in the event of a sensor failure. NOTE: The VisiPro DO Ex sensor is not intended and specified as a safety device. A SIL (Safety Integrity Level) certification is not available. It is in the sole responsibility of the user to validate the VisiPro DO Ex sensor according the safety requirements of his application. 3 Safety Precautions and Hazards ATTENTION! read the following safety instruc-

tions carefully before installing and operating the VisiPro dO sensor. 3.1 General Precautions For safe and correct use of VisiPro DO Ex, it is essential that both operating and service personnel follow generally accepted safety procedures as well as the safety instructions given in this docu-

ment, the VisiPro DO Ex operation instruction manual. The specification given in the Specification Sheet as regards temperature, pressure etc. may under no circumstances be ex-

ceeded. Inappropriate use or misuse can be dangerous. The lifetime of the VisiPro DO Ex highly depends on the specific conditions of the application. Temperature, pressure, chemicals used may accelerate the ageing of both the sensor and its ODO cap. See chapter 7 for replacement conditions. Cleaning, assembly and maintenance should be performed by per-

sonnel trained in such work. Before removing the sensor from the measuring setup, always make sure the no process medium can be accidentally spilled. When removing and cleaning the sensor, it is recommended to wear safety goggles and protective gloves. The sensor can not be repaired by the operator and has to be sent back to Hamilton for inspection. Necessary precautions should be taken when transporting the sensors. For repair or shipment the sensor should be sent back in the original reusable packaging box. Every VisiPro DO Ex sent back for repair must be decontaminated. If the conditions described in these operating instructions manual are not adhered to or if there is any inappropriate interference with the equipment, all of our manufacturers warranties become obsolete. 3.2 Operation of VisiPro DO Ex Sensor When using the VisiPro DO sensors in process environment suitable protective clothing, safety glasses and protective gloves must be worn, particularly when dealing with a malfunction where the risk of contamination from spilled liquids exists. Installation and maintenance of sensors must be performed only by trained personnel. The mobile devices and sensors must be used for their intended applications, and in optimum safety and opera-

tional conditions. 5 SAFETy PrECAuTIONS AN d HA zArd S SAFETy PrECAuTIONS AN d HA zArd S Use only wired digital or analog connection for the process con-

trol. The Arc wireless interface is designed for sensor monitoring, maintenance and service purposes. If the sensor is used in contact with gaseous or liquid organic solvents, the resulting measurement accuracy in this application must be separately checked and validated by the customer. Make sure that the PG13,5 thread and the O-ring are not dam-

aged when screwing the sensor into the process. O-rings are consumable parts which must be exchanged regularly (at least once per year). Even when all required safety measures have been complied with, potential risks still exist with respect to leaks or mechanical damage to the armature. Wherever there are seals or screws, gases or liquids may leak out undetected. Always make sure that no process medium can be accidentally spilled before removing the sensor from its measurement setup. Make sure that no air or gas bubbles sticks to the sensitive part of the sensor. As a consequence, the measurement value could be un-

stable. Do not put stress on the system by vibration, bending or torsion. Before use, verify that the sensor is properly configured for your application. Failure to observe and carry out the maintenance procedures may impair the reliability and correct functioning of the measure-

ment system. ATTENTION! When unscrewing the PG 13.5 thread connection never turn the sensor at the connector head because you can loosen the OdO Cap from the sensor shaft and fluid can reach the interior of the sensor. ATTENTION! To avoid humidity problems, make sure that the OdO Cap is always attached firmly to the sensor shaft, and that the O-ring between the shaft and cap is undamaged. The integrated 420 mA analog output has been configured according to factory defaults. You can find full details, including serial number and most important specifications, on the certificate provided with each sensor. Before use, verify that the sensor is properly configured for your application. Make sure that following cross sensitivities and resistances of ODO Caps are respected. Cross sensitivities and resistances of ODO Cap H0 Measurement not influenced by Carbon Dioxide Wetted parts resistant to Ethanol Wetted parts not resistant to Chlorine, Ozone and Organic Solvents such as Acetone, Tetrahydrofuran THF*

loaded from www.hamiltoncompany.com 3.3.1 General Conditions for Safe Operation Conditions described in the ATEX EC-Type Examination Certifi-

cate or the IECEx Certificate of Conformity must be adhered to. The operator of equipment in potentially explosive atmospheres is responsible for ensuring that all components of the system are certified for that area classification and are compatible with each other. The regulation of erection (e.g. EN 60079-14) which apply to systems and plants used in potentially explosive atmospheres have to be strictly adhered to. Perform regular visual inspection of the sensor, its installation and cable for intactness and correct operational conditions. If the sensor is being operated in gas atmosphere, the following process and ambient temperatures have to be observed:

ance with the locally applicable regulations. Along to the intrinsically safe circuit potential equalization has to be provided, because in case of a fault the intrinsically safe circuit has to be regarded as connected to the metal housing. Intense vapor or dust directly impacting on the cable must be avoided when the cable is running through zones of category 1G, 1D or 2D. Assembly and maintenance are to be done only if the atmosphere is Ex-free and according to the current local regula-

tions. After maintenance works have been performed all barriers and notes remove for that purpose have to be put back in their original place. The sensor has to be powered with a power supply unit with an intrinsically safe output circuit of Ex ia IIC. For the selection, consider the conditions stated in EN 60079-25. This is also applicable for operation of the sensor in non-ex environment. In non-ex environment, VisiPro DO Ex can be operated with the Sensor Power Cable M12.

cations of the power supply units. ATTENTION! In case the sensor is not working correctly disconnect the sensor immediately from the power supply. 3.3.2 Earthing The sensor has to be mounted at the mounting location electro-

statically conductive (< 1M). It is recommended to assign the sensor shaft and/or M12 cable shield to ground or earth espe-

cially in electromagnetically noisy environments. This significantly improves noise immunity and signal quality. The M12 thread is connected to the metallic housing of the VisiPro DO Ex sensor. Two options for connecting the sensor to the process environ-

ment are available. Option 1: The Metal tank is connected to earth The sensor shaft is connected to the metal tank over the PG 13.5 thread. Do not connect the green yellow shield wire of the M12 cable to earth. It must remain unconnected and can be cut off. X Figure 1: Metal tank with earth connection NOTE: If the tank is not connected to earth, Option 2 has to be applied. Option 2: Glass or plastic tank

(not connected to earth) The glass or plastic tank has no connection to earth and therefore it is necessary to connect the sensor shaft via a screw clamp to earth. 9 SAFETy PrECAuTIONS AN d HA zArd S PrOdu CT dESC rIPTION X Figure 2: Glass or plastic tank with no earth connection Below are shown several examples how to connect the shaft of the sensor directly to earth as required in Figure 2. External earth cable Figure 3: Example clamps for connecting the earth to armature and metallic housing of the tank. 3.4 Electrical Safety Precautions Do not connect the sensor to a power source of any voltage beyond the range stated in the power rating Technical Specifi-

cations (www.hamiltoncompany.com). Always use Hamilton M12 cables for safe connection. Cables are available in a broad range of lengths (Chapter 10). Make sure the cable is intact and properly plugged to avoid any short circuit. Keep VisiPro DO Ex away from other equipment which emits electromagnetic radio frequency fields, and minimize static electricity in the immediate environment of the optical measuring parts.Carefully follow all the instructions in chapter 5.3 to avoid electrical damage to the sensor. The contacts must be clean and dry before sensor is connected to the cable. ATTENTION! Switch off the power supply and unplug the connector before dismounting the VisiPro dO Ex. ATTENTION! If the power supply (220 VAC/24VdC) is switched off or disconnected the reading on the PCS is wrong. Hazard Precautions 3.5 Chemical, Radioactive or Biological Selection of the appropriate safety level and implementation of the required safety measures for working with VisiPro DO Ex is the sole responsibility of the user. If working with hazardous liquids observe and carry out the maintenance procedures, paying particular attention to cleaning and decontamination. If VisiPro DO Ex becomes contaminated with biohazardous, radioactive or chemical material, it should be cleaned. Failure to observe and carry out the maintenance procedures may impair the reliability and correct functioning of the measuring module. 4 Product Description 4.1 General Description The VisiPro DO Ex was the first optical dissolved oxygen (DO) sensor for use in explosive environment. With their integrated transmitter, VisiPro DO Ex sensors enable direct communication to the process control system via 2 wire 4-20 mA standard signal or digital HART. Wireless communication directly from the sensor may be used for monitoring, configuration and calibration, and saves time without compromising the quality of the wired connec-

tion. The sensor features furthermore an integrated Bluetooth 4.0, enabling in this way wireless data exchange with smartphones and tablets. VisiPro DO Ex optical technology improves the measuring per-

formance and simplifies maintenance. Improvements compared to conventional electrochemical (amperometric) sensors include flow independence, rapid start-up with no polarization time, and simplified maintenance. With the transmitter integrated, VisiPro DO Ex sensors provide more reliable measurements directly to your process control system. The -transmitter located in the sensor head stores all relevant sensor data, including calibration and diagnostic informa-

tion, simplifying calibration and maintenance. The integrated quality indicator predicts the remaining sensor and cap life time. Key benefits include:

Optical measurement in explosive environment with ATEX / IECEx certification No separate transmitter needed Simple maintenance with robust industrial design Easy to install 2-wire connection Direct analog or digital HART communication to the process control system via 2 wire 4-20mA standard signal. Full online wireless option via Bluetooth 4.0 for easy monitoring, configuration and calibration 4.2 Hardware Description The VisiPro DO Ex sensor consists of a sensor head with inte-

grated electronic and a sensor shaft in contact with the measured medium. The sensor shaft is terminated by the optical dissolved 11 PrOdu CT dESC rIPTION INSTALLATION oxygen (ODO) cap, carrying the oxygen sensitive luminophore. During development, special attention was paid to an optimum sanitary design. All materials in contact with the solution meet the FDA requirement. Sensor status LED of the sensor:

The luminescence of certain organic pigments (luminophore) is quenched in the presence of oxygen. The luminophore absorbs the excitation light and release a part of the absorbed energy by emission of fluorescence. In the pres-

ence of oxygen, energy transfer takes place from the excited luminophore to oxygen. The luminophore does not emit fluore-

cence and the measurable fluorescence signal decreases. Fluorescence process (without oxygen) 1 Light (excitation) Luminophore Light Absorption Excited State Fluorescence

Failure to do so may lead to damages or measurement failure. 1) Remove the protective caps from the VisiPro DO Ex shaft, and from the M12 sensor head 2) Mount the O-ring on the sensor shaft and screw the ODO Cap firmly (Chapter 9.1) 3) Verify the functionality of the sensor including the ODO cap (Chapter 7.1) 4) Calibrate the sensor (Chapter 7.3) 5) Connect the sensor to the process control system (Chapter 5) 6) Verify the measurement in air on your control system 7) Mount the sensor to the armature or process connection

(Chapter 5.3) NOTE: No oxygen measurement is performed at a temperature higher than 85C to protect the optoelec-

tronics and enhanced the sensor lifetime. 21 mAINTENANCE mAINTENANCE 7 Maintenance Periodic maintenance routines need to be run in order to ensure safe and reliable operation and measurement of sensor and the accessories. ATTENTION! Avoid any contact of the equipment with corrosive media. ODO Cap Functionality 7.1 Verify Sensor Status and 1) Power the sensor with the M12 Sensor Power Cable and connect the sensor to ArcAir. 2) Control the traffic lights (Figure 11). 3) Please refer to the troubleshooting (Chapter 8) for the next steps if the traffic light is not green. 4) Control the quality of the ODO cap in Sensor Status /

Quality Counter and Temperature / Quality Indicator and change the ODO Cap or sensor if required (Chapter 7.2). NOTE: The lifetime of the VisiPro DO Ex highly depends on the specific conditions of the application. Temperature, pressure, chemicals used may accelerate the ageing of both the sensor and its ODO cap. A warning DO Replace Sensor Cap remains active as long as the sensor quality is below 35%. Make sure that after new cap replacement the sensor reaches at least 60% cap quality. The quality indicator takes sensor and cap into account. The sensor is performing correctly. No errors or warnings have been registered. At least an error or a warning has been registered. Verify the sensor errors and warnings in Sensor Status. No communication between the sensor and ArcAir. This may be due to a hardware failure. Figure 11: Description of the traffic lights on ArcAir 7.2 Replacing the ODO Cap The exchange of ODO Cap is performed very easily:

1) Unscrew the ODO cap from the shaft (Figure 12). 2) Exchange the O-ring. 3) Screw firmly the new ODO Cap onto the sensor shaft again. 4) Perform sensor calibration (Chapter 7.3). NOTE: If the ODO Cap is mounted very firmly on the shaft, and if you cannot obtain a good grip on the stainless steel with your fingers, a silicone tube between your fingers and metal may supply a better grip. O-ring unscrew Figure 12: Replacing the ODO cap 7.3 Calibration The VisiPro DO Ex sensors provide two kinds of sensor calibra-

tion: automatic standard calibration, and product calibration. The automatic standard calibration and the product calibration may be performed using ArcAir (see chapter 5.2). with ArcAir 7.3.1 Automatic Standard Calibration VisiPro DO Ex sensors are calibrated at two points: in air and in an oxygen-free environment. During calibration, the sensor controls automatically the stability of the oxygen and temperature signals. NOTE: For greater measurement accuracy insure that temperature difference between calibration medium and process medium is minimal. 7.3.2 Zero Point Calibration

(Point Zero Oxygen) 1) Install the sensor into the calibration station and connected the Nitrogen calibration gas (Figure 13). 2) Power the VisiPro and connect to ArcAir via the Arc Wireless Converter BT. 3) Select the sensor in the sensor list. 4) Open the Calibration tab. 5) Select Zero Point calibration. 6) Immerse the sensor into an oxygen-free environment (Figure 13) for e.g. nitrogen. Verify that the flow rate does not exceed 0.5 L/min and avoid overpressure. 7) Click Start to start the calibration wizard. 8) Follow the instructions on the screen. 23 mAINTENANCE mAINTENANCE Sensor for calibration in zero oxygen Tube: on the top open

dium (Figure 14). 2) Power the VisiPro and connect to ArcAir via the Arc Wireless Converter BT. 3) Select the sensor in the sensor list. 4) Open the Calibration tab. 5) Select Calibration Point Air 6) Click Start to start the calibration wizard. 7) Follow the instructions on the screen. O2 H2O Figure 14: Calibration setup in saturated medium NOTE: Calibration with air-saturated water is less accurate due to the slow saturation process of air in water. NOTE: The value of the saturated oxygen concentration at different temperatures, different pressures and air humidity play an important role for the calibration of dissolved oxygen. VisiPro DO Ex refers to a concentra-

tion in water saturated air and from the factory settings of atmospheric pressure of 1013 mbar at 25C. For an accurate calibration Hamilton recommends to use oxygen saturated pure water. 7.4 Product calibration The product calibration is an in-process calibration procedure in order to adjust the measurement to specific process conditions. Product calibration is an additional calibration procedure to a standard calibration. If product calibration is activated, the VisiPro DO Ex calibration curve is calculated from the data of last calibration at point 1 and from the data of the product calibration (Figure 15). In order to restore the original standard calibration curve, the product calibration can be at any time by selecting on the Product calibra-

tion command cancel. A new standard calibration cancels a product calibration as well. Figure 15: Effect of a product calibration (CP6) on an existing standard calibration function based on the Zero Point Calibration (CP 1) and the Air Calibration (CIP 2). NOTE: The product calibration is possible for DO values in the range of 2 to 55 %-vol (20 550 mbar pO2). A product calibration is performed as follows:

1) Connect one of the VisiPro DO sensor with the power supply, e.g. Sensor Power Cable M12 Ref 355288 t (see figure xx) and install a Wireless Converter BT Ref 242333. 2) Select the desired sensor from the sensor list 3) Go to Process Settings 25 mAINTENANCE TrOuBLESHOOTING 4) Click Start to start the product calibration wizard 5) Follow the instruction on the screen 8 Troubleshooting NOTE: Alternatively, the product calibration may be performed with a field device on side the measuring point. 7.5 Cleaning This chapter outlines a manual cleaning procedure for the care and maintenance of optical dissolved oxygen (ODO) sensors including a procedure for the cleaning the sensing membrane in particular. Cleaning the Sensor Carry out the cleaning procedure as follows:

1) Remove sensor from the measuring setup. 2) Check if the ODO Cap is mounted firmly on the shaft. 3) Soak a dust-free cloth or tissue paper with water and wipe the wetted parts with it. Thoroughly rinse the wetted parts and the sensing membrane with deionised water afterwards. 4) Dry the wetted parts with a clean dust-free cloth or tissue and store the sensor in dry and dark conditions (ODO Caps are light-sensitive). 5) If the sensing-membrane on the front of the cap is contaminated with oil, grease or other organic matter, soak a clean dust-free cloth with isopropyl alcohol. Rinse residual isopropyl alcohol immediately from the membrane with deionised water and gently wipe over the membrane. 6) After cleaning always perform a new calibration before carrying out measurements. (See chapter 7.3 in the corresponding Operating Instruction Manual) ATTENTION: Cleaning, assembly and maintenance should be performed by personnel trained in such work. do not use any abrasive tissues or cleaning materials and do not use any cleaning chemicals other then described above. Before removing the sensor from the measuring setup, always make sure that the setup is pressure-less and cold and that no process medium can be accidentally spilled. When removing and cleaning the sensor, it is recommended to wear safety glasses and protective gloves. 8.1 Sensor Self-Diagnostic VisiPro DO Ex sensors provide a self-diagnostic functionality to detect and identify the most common sensor malfunctions. Both interfaces, analog 4-20 mA or digital HART, may provide warning and error messages. The analog 420 mA interface can be con-

figured according to the NAMUR recommendations to indicate an abnormal event (See chapter 5.2.3). Use ArcAir for monitoring the sensor status and for troubleshooting. The following types of messages are provided by the self-diagnosis function. 8.1.1 Warnings Warning Cause / Solution DO reading below lower limit The oxygen reading is too low

(DO < 0%-sat). Make a new zero-point calibration (Chapter 7.3.2) DO reading above upper limit The oxygen reading is too high

(DO > 300 %-sat). Make a new calibration in oxygen saturated medium. (See chapter 7.3.3). If not successful, replace the sensor cap. DO reading unstable If continuously happening, use a new cap or check the process regulation. If the problem still appears, call our Technical Support. T reading below lower limit T reading above upper limit Measurement not running The temperature is below the user defined measurement temperature range. If the process temperature is outside this range, the sensor will not perform DO readings. The temperature is above the user defined measurement temperature range. If the process temperature is outside this range, the sensor will not perform DO readings. The measurement interval is set to 0 or the measurement temperature is out of the range. DO calibration recommended Perform a calibration in order to ensure reliable measurement.(Chapter 8.2) DO last calibration not successful The last calibration failed. The sensor is using the old successful calibration values. In order to ensure reliable measurement perform a new calibration

Regardless of this, Hamilton Bonaduz AG cannot assume liability for any errors in this manual or for their consequences. 3 GENErAL INFOrm ATION SAFETy PrECAuTIONS AN d HA zArd S 1 General Information 3 Safety Precautions and Intended Use 1.1 The VisiTrace DO sensors are intended for the measurement of dissolved oxygen (DO) in aqueous solutions in ppb range from 0 - 2000 ppb. If the sensor is used in contact with gaseous or liquid organic sol-

vents, the resulting measurement accuracy in this application must be separately checked and validated by the customer. ATTENTION! The VisiTrace dO sensor has a built-in temperature sensor (NTC 22k). This temperature sensor is to be used only for monitoring the sensor conditions, not for controlling the process temperature. ATTENTION! The measurement values transmitted over wireless communication are not intended to be used for process control. 1.2 About this Operating Instruction These Operating Instructions are designed to support the inte-

gration, operation and qualification of the VisiTrace DO sensor. To achieve this, it will describe the features of VisiTrace DO and its integration in Process Control Systems (PCS). Both the hardware and the communication between the VisiTrace DO and Process Control Systems are described in this manual. After reading this manual the user should be capable of installing and operating VisiTrace DO sensors. ATTENTION! Essential information for avoiding personal injury or damage to equipment. NOTE: Important instructions or interesting information. 2 Liability The liability of Hamilton Bonaduz AG is detailed in the document General Terms and Conditions of Sale and Delivery. Hamilton is expressly not liable for direct or indirect losses arising from use of the sensors. It must in particular be insured in this con-

junction that malfunctions can occur on account of the inherently limited useful life of sensors contingent upon their relevant applica-

tions. The user is responsible for the calibration, maintenance and regular replacement of the sensors. In the case of critical sensor ap-

plications, Hamilton recommends using back-up measuring points in order to avoid consequential damages. The user is responsible for taking suitable precautions in the event of a sensor failure. Hazards ATTENTION! read the following safety instruc-

tions carefully before installing and operating the VisiTrace dO sensor. 3.1 General Precautions For safe and correct use of VisiTrace DO, it is essential that both operating and service personnel follow generally accepted safety procedures as well as the safety instructions given in this docu-

ment, the VisiTrace DO operating instruction manual. The specification given in the Specification Sheet as regards temperature, pressure etc. may under no circumstances be ex-

ceeded. Inappropriate use or misuse can be dangerous. The lifetime of the VisiTrace DO highly depends on the specific conditions of the application. Temperature, pressure, chemicals used may accelerate the ageing of both the sensor and its ODO cap. See chapter 7 for replacement conditions. Cleaning, assembly and maintenance should be performed by per-

sonnel trained in such work. Before removing the sensor from the measuring setup, always make sure that no process medium can be accidentally spilled. When removing and cleaning the sensor, it is recommended to wear safety goggles and protective gloves. The sensor can not be repaired by the operator and has to be sent back to Hamilton for inspection. Necessary precautions should be taken when transporting the sensors. For repair the sensor should be sent back in the original reusable packaging box. Every VisiTrace DO sent back for repair must be decontaminated. If the conditions described in these operating instructions manual are not adhered to or if there is any inappropriate interference with the equipment, all of our manufacturers warranties become obsolete. 3.2 Operation of VisiTrace DO Sensor When using the VisiTrace DO sensors in process environment suitable protective clothing, safety glasses and protective gloves must be worn, particularly when dealing with a malfunction where the risk of contamination from spilled liquids exists. Installation and maintenance of sensors must be performed only by trained personnel. The mobile devices and sensors must be used for their intended applications, and in optimum safety and opera-

tional conditions. Use only wired digital or analog connection for the process con-

trol. The Arc wireless interface is designed for sensor monitoring, maintenance and service purposes. Make sure that the PG13,5 thread and the O-ring are not dam-

aged when screwing the sensor into the process. O-rings are consumable parts which must be exchanged regularly (at least once per year). Even when all required safety measures have been complied with, potential risks still exist with respect to leaks or mechanical damage to the armature. Wherever there are seals 5 SAFETy PrECAuTIONS AN d HA zArd S SAFETy PrECAuTIONS AN d HA zArd S Option 1: The Metal tank is connected to earth The sensor shaft is connected to the metal tank over the PG13,5 thread. Do not connect the green yellow shield wire of the M12 cable to earth. It must remain unconnected and can be cut off. or screws, gases or liquids may leak out undetected. Always make sure that no process medium can be accidentally spilled before removing the sensor from its measurement setup. Make sure that no air or gas bubbles sticks to the sensitive part of the sensor. As a consequence, the measurement value could be un-

stable. Do not put stress on the system by vibration, bending or torsion. Before use, verify that the sensor is properly configured for your application. Failure to observe and carry out the maintenance procedures may impair the reliability and correct functioning of the measure-

ment system. ATTENTION! When unscrewing the PG13,5 thread connection never turn the sensor at the connector head because you can loosen the OdO Cap from the sensor shaft and fluid can reach the interior of the sensor. ATTENTION! To avoid humidity problems, make sure that the OdO Cap is always attached firmly to the sensor shaft, and that the O-ring between the shaft and cap is undamaged. The integrated 420 mA analog output has been configured according to factory defaults. You can find full details, including serial number and most important specifications, on the certificate provided with each sensor. Before use, verify that the sensor is properly configured for your application. The ODO Caps are consumable parts of the VisiTrace DO. The operating lifetime of the ODO Caps depend strongly on the op-

erating conditions of the process. Make sure that following cross sensitivities and resistances of ODO Caps are respected. Cross sensitivities and resistances of ODO Cap L0 Wetted parts resistant to Standard cleaning solution

(CIP, NaOH) Wetted parts chemical stabilized against Standard disinfectant solutions

(active chlorine, chlorine dioxide) Wetted parts not resistant to Organic Solvents such as Acetone, Tetrahydrofuran THF*

If the sensor is used in contact with gaseous or liquid organic solvents, the resulting measurement accuracy and stability in those applications must be separately checked and validated by the customer. 3.3 Earthing The sensor has to be mounted at the mounting location which has to be electrostatically conductive (< 1M). It is recommended to assign the sensor shaft and/or M12 cable shield to ground or earth especially in electromagnetically noisy environments. This significantly improves noise immunity and signal quality. The M12 thread is connected to the metallic housing of the VisiTrace DO sensor. Two options for connecting the sensor to the process environment are available. Figure 1: Metal tank with earth connection NOTE: If the tank is not connected to earth, Option 2 has to be applied. Option 2: Glass or plastic tank (not connected to earth) The glass or plastic tank has no connection to earth and therefore it is necessary to connect the sensor shaft via a screw clamp to earth. X X Figure 2: Glass or plastic tank with no earth connection Below are shown several examples on how to connect the shaft of the sensor directly to earth as required in Figure 2. External earth cable Figure 3: Example clamps for connecting the earth to armature and metallic housing of the tank. 7 PrOdu CT dESC rIPTION PrOdu CT dESC rIPTION 3.4 Electrical Safety Precautions Do not connect the sensor to a power source of any voltage beyond the range stated in the power rating Technical Specifi-

cations (www.hamiltoncompany.com) Always use Hamilton M12 cables for safe connection. Cables are available in a broad range of lengths. Make sure the cable is intact and properly plugged to avoid any short circuit. Keep VisiTrace DO away from other equipment which emits electromagnetic radio frequency fields, and minimize static electricity in the immediate environment of the optical measuring parts. Carefully follow all the instructions in chapter 5.3 to avoid electrical damage to the sensor. The contacts must be clean and dry before sensor is connected to the cable. ATTENTION! Switch off the power supply and unplug the connector before dismounting the VisiTrace dO. ATTENTION! If the power supply (230VAC/24VdC) is switched off or disconnected the readon on the PCS is wrong. 3.5 Chemical, Radioactive or Biological Hazard Precautions Selection of the appropriate safety level and implementation of the required safety measures for working with VisiTrace DO is the sole responsibility of the user. If working with hazardous liquids observe and carry out the maintenance procedures, paying particular attention to cleaning and decontamination. If VisiTrace DO becomes contaminated with biohazardous, radioactive or chemical material, it should be cleaned. Failure to observe and carry out the maintenance procedures may impair the reliability and correct functioning of the measuring module. 4 Product Description 4.1 General Description The VisiTrace DO sensors is intended for the measurement of dissolved oxygen (DO) in aqueous solutions in ppb rang from 0 - 2000 ppb and for use in explosive environment. With their integrated transmitter, VisiTrace DO sensors enable direct con-

nection to the process control system via 2 wire 4-20 mA stan-

dard signal. Wireless communication directly from the sensor may be used for monitoring, configuration, calibration and saves time without compromising the quality of the wired connection. The sensor features furthermore an integrated Bluetooth 4.0, enabling in this way wireless data exchange with smartphones and tablets. VisiTrace DO optical technology improves the measuring per-

formance and simplifies maintenance. Improvements compared to conventional electrochemical (amperometric) sensors include flow independence, rapid start-up with no polarization time, and simplified maintenance. With the transmitter integrated, VisiTrace DO sensors provide more reliable measurements directly to your process control system. The -transmitter located in the sensor head stores all relevant sensor data, including calibration and diagnostic infor-

mation, simplifying calibration and maintenance. The integrated quality indicator predicts the remaining sensor and cap life time. Key benefits include:

Optical measurement in explosive environment with ATEX / IECEx certification No separate transmitter needed Simple maintenance with robust industrial design Easy to install 2-wire connection Direct connection to the process control system via 2 wire 4-20mA standard signal. Full online wireless option via Bluetooth 4.0 for easy monitoring, configuration and calibration 4.2 Hardware Description The VisiTrace DO sensor consists of a sensor head with inte-

grated electronic and a sensor shaft in contact with the measured medium. The sensor shaft is terminated by the optical dissolved oxygen (ODO) cap, carrying the oxygen sensitive luminophore. During development, special attention was paid to an optimum sanitary design. Sensor status LED of the sensor:

The luminescence of certain organic pigments (luminophore) is quenched in the presence of oxygen. The luminophore absorbs the excitation light and release a part of the absorbed energy by emission of fluorescence. In the presence of oxygen, energy transfer takes place from the excited lumino-

phore to oxygen. The luminophore does not emit fluorecence and the measurable fluorescence signal decreases. Fluorescence process (without oxygen) 1 Light (excitation) Luminophore Light Absorption Excited State Fluorescence

ilton process housings, including Flexifits, Retractexs, Retractofits and Hygienic Sockets. Before installing the armatures, you should test that the seal is tight and the parts are all in working order. Ensure that there is no damage to the sensor or the armature. Check whether all O-rings are in place in the appropriate grooves and are free of damage. To avoid any mechanical damage to O-rings on assembly, they should be slightly greased. Please note that O-rings are wetted parts and greasy compounds must comply to your FDA application needs. 5.3.2 M12 Pin Designation The VisiTrace DO sensor is fitted with a M12 male, A coded con-

nector. The four golden contacts are denoted as pin 1 to pin 4. For easy identification of each pin the M12 has a mark between pin 1 and pin 2. Always use Hamilton M12 sensor cables for safe connection, which are available in different lengths (Chapter 11). 3 2 4 1 Housing Figure 8: Requirements for electrical connection of VisiTrace DO sensors NOTE: Shaft potential is isolated from the 4-20mA +

Only use the sensor within the specifications (www.hamiltoncompany.com). Failure to do so may lead to damages or measurement failure. 1) Remove the protective caps from the VisiTrace DO shaft, and from the M12 sensor head 2) Mount the O-ring on the sensor shaft and screw the ODO Cap firmly (Chapter 7.2) 3) Verify the functionality of the sensor including the ODO cap (Chapter 7.1) 4) Calibrate the sensor (Chapter 7.3) 5) Connect the sensor to the process control system (Chapter 5) 6) Verify the measurement in 1%vol. oxygen on your control system 7) Mount the sensor to the armature or process connection

(Chapter 5.3) NOTE: No oxygen measurement is performed at a temperature higher than 85C to protect the optoelec-

tronics and enhanced the sensor lifetime. Periodic maintenance routines need to be run in order to ensure safe and reliable operation and measurement of sensor and the accessories. 19 A Sensor M12 Pin 3 M12 Pin 2 420 mA PCS (remote I/O active) 420 mA 4-20 mA / +24VDC 4-20 mA / 0VDC; Ground 7 Maintenance mAINTENANCE mAINTENANCE ATTENTION! Avoid any contact of the equipment with corrosive media. 7.1 Verify Sensor Status and ODO Cap Functionality 1) Power the sensor with the M12 Sensor Power Cable and connect the sensor to ArcAir. 2) Control the traffic lights (Figure 11). 3) Please refer to the troubleshooting (Chapter 8) for the next steps if the traffic light is not green. 4) Control the quality of the ODO cap in Sensor Status /

Quality Counter and Temperature / Quality Indicator and change the ODO cap if required (Chapter 7.2). NOTE: The lifetime of the VisiTrace DO sensor highly depends on the specific conditions of the application. Temperature, pressure, chemicals used may accelerate the ageing of both the sensor and its ODO cap. A warning DO Replace Sensor Cap remains active as long as the sensor quality is below 35%. Make sure that after new cap replacement the sensor reaches at least 60% cap quality. The quality indicator takes sensor and cap into account. The sensor is performing correctly. No errors or warnings have been registered. At least an error or a warning has been registered. Verify the sensor errors and warnings in Sensor Status. No communication between the sensor and ArcAir. This may be due to a hardware failure. Figure 11: Description of the traffic lights on ArcAir 7.2 Replacing the ODO Cap The exchange of ODO Cap is performed very easily:

1) Unscrew the ODO cap from the shaft (Figure 12). 2) Exchange the O-ring. 3) Screw firmly the new ODO Cap onto the sensor shaft again. 4) Perform sensor calibration (Chapter 7.3). NOTE: If the ODO Cap is mounted very firmly on the shaft, and if you cannot obtain a good grip on the stainless steel with your fingers, a silicone tube between your fingers and metal may supply a better grip. O-ring unscrew Figure 12: Replacing the ODO cap 7.3 Calibration The VisiTrace DO sensors provide two calibration points: a zero-point calibration and a calibration at 1%-vol. oxygen (400 ppb at 25C). For many applications a regular calibration of the zero-point (chapter 7.3.2) is sufficient to ensure good sen-

sor performance in low ppb range. The oxygen accuracy of the oxygen point at 1%-vol. is to be verified regularly (chapter 7.3.3). If the accuracy of the oxygen point at 1%-vol. is below the process specification recalibration is required (chapter 5.2.5). 7.3.1 Materials and Method VisiTrace DO sensors are calibrated at two points: in 1%vol. oxygen and in an oxygen-free environment. During calibration, the sensor controls automatically the stability of the oxygen and temperature signals. Purpose Hamilton REF Enables accurate calibration of the zero-point n.a.

Product calibration is an additional calibration procedure to a standard calibration. If product calibration is activated, the VisiTrace DO calibration curve is calculated from the data of last calibration at point 1 and from the data of the product calibration (Figure 16). In order to restore the original standard calibration curve, the product calibration can be at any time by selecting on the Product calibra-

tion command cancel. A new standard calibration cancels a product calibration as well. Figure 16: Effect of a product calibration (CP6) on an existing standard calibration function based on the Zero Point Calibration (CP 1) and the 1%vol. oxygen point (CP 2). This chapter outlines a manual cleaning procedure for the care and maintenance of optical dissolved oxygen (ODO) sensors including a procedure for the cleaning the sensing membrane in particular. Cleaning the Sensor Carry out the cleaning procedure as follows:

1) Remove sensor from the measuring setup. 2) Check if the ODO Cap is mounted firmly on the shaft. 3) Soak a dust-free cloth or tissue paper with water and wipe the wetted parts with it. Thoroughly rinse the wetted parts and the sensing membrane with deionised water afterwards. 4) Dry the wetted parts with a clean dust-free cloth or tissue and store the sensor in dry and dark conditions (ODO Caps are light-sensitive). 5) If the sensing-membrane on the front of the cap is contami-

nated with oil, grease or other organic matter, soak a clean dust-free cloth with isopropyl alcohol. Rinse residual isopropyl alcohol immediately from the membrane with deionised water and gently wipe over the membrane. 6) After cleaning always perform a new calibration before carry-

ing out measurements. (See chapter 7.3 in the corresponding Operating Instruction Manual) ATTENTION! Cleaning, assembly and mainte-

nance should be performed by personnel trained in such work. do not use any abrasive tissues or clean-

ing materials and do not use any cleaning chemicals other then described above. Before removing the sensor from the measuring setup, always make sure that the setup is pressure-less and cold and that no process medium can be accidentally spilled. When removing and cleaning the sensor, it is recommend-

ed to wear safety glasses and protective gloves. 25 TrOuBLESHOOTING TrOuBLESHOOTING 9 Troubleshooting 9.1 Sensor Self-Diagnostic VisiTrace DO sensors provide a self-diagnostic functionality to detect and identify the most common sensor malfunctions.

GENERAL TERMS AND CONDITIONS OF SALE FOR CAPITAL PURCHASE APPLICABILITY 1 1.1 These terms and conditions of sale (Terms) are the only terms which govern the sale of the product and services (Goods) by Hamilton Company,

(Hamilton) a Nevada corporation, and the purchaser of Goods (Customer). Notwithstanding anything herein to the contrary, if a written contract signed by both parties is in existence covering the sale of the Goods covered hereby, the terms and conditions of said contract shall prevail to the extent they are inconsistent with these Terms. 1.2 These Terms are applicable to all transactions ("Purchase Agreement") between Customer and Hamilton, including those which represent the implementation of any standard or specialized solution utilizing the Goods for throughput, assay, or other clinical or laboratory function (Hamilton Solution). A Hamilton Solution is not a specific part number, but rather is a process utilizing the Goods. As such, specific parts listed within the quotation may require substitution, addition, or subtraction of specified parts. Customer hereby acknowledges and agree that Hamilton has the authority to make such changes to the line items within the quotation and the Purchase Agreement necessary to implement the Hamilton Solution, provided that such changes do not materially diminish the performance, quality or utility of the Hamilton Solution. In order to meet the needs of State and County tax laws for products and services, it is necessary to place purchase orders ("Purchase Orders") with Hamilton with a single price and associated reference to a specific quotation to which such price relates, or by line item as they appear in the final quotation. Tax will be determined and set out within the invoice for the Goods. 1.3 2 QUOTATIONS Quotations shall only be binding if they contain a stated period of validity and upon approval of credit application per consent from the Hamilton finance department. DELIVERY 3 3.1 The estimated delivery time of Goods will be stated in each quotation and will be dependent upon multiple factors such as current resource workload, third-

party item delivery times, hardware creation times and software application development time. The delivery time starts with the date of Hamilton order acknowledgment and ends when the shipment is ready for dispatch or a site acceptance test if required, as stated within the applicable quotation. Hamilton will use all means necessary to deliver product as mutually agreed to, and will keep the Customer informed of possible delays if applicable. Compliance with the delivery time is conditional upon the Customer fulfilling their Purchase Agreement contractual obligations, e.g. notification of all essential technical specifications, availability of samples, import permits, down payments, letters of credit etc. 3.2 The delivery time is reasonably extended if one of the cases applies:

3.2.1 The information required by Hamilton for performance of the Purchase Agreement is not received in time, or if the customer subsequently changes a Purchase Agreement thereby causing a delivery delay of the Goods. All changes requested by the customer require a revised Purchase Order from the customer. 3.2.2 Hindrances occur which prevent Hamilton from performing a Purchase Agreement by force majeure. Hindrances include epidemics, mobilization, war, revolution, serious breakdowns in the works, accidents, labor conflicts, late or deficient delivery by subcontractors of raw materials, semi-finished or finished products, official actions or omissions by any state authorities or public bodies, and natural catastrophes. If the Customer claims damages for delayed delivery, it must be proven that the delay was caused through Hamiltons fault and that the Customer has suffered a loss as a result of such delay. If substitute material can be supplied to accommodate the Customer, the latter is not entitled to claim any delay damages. Any delayed delivery does not entitle the Customer to any rights and claims other than those expressly stipulated herein. SHIPPING TERMS, TITLE & RISK OF LOSS 4 4.1 Delivery shall be made F.O.B. Hamilton. Title and risk of loss pass to Customer upon delivery of the Goods to the common carrier. 4.2 Costs associated with shipping and delivery ("Freight ") shall be charged to Customer at the rates negotiated and set forth pursuant to the Purchase Order and 4.3 When assistance from third-party riggers is required to assist with placement of Goods, the expense will be added to the Freight charges. Disposal of all invoice, with the invoice to govern any discrepancy between the two. packaging and packing materials is the Customers responsibility. 5 ACCEPTANCE Unless otherwise agreed upon in writing, acceptance shall be affected immediately after installation at the Customer's premises. In addition, acceptance shall also be deemed completed when: (i) Hamilton has satisfied its standard installation qualification to show performance to manufacturers specification or exceptional conditions agreed upon in writing with the Customer prior to acknowledgment of the Purchase Order by Hamilton; or (ii) as soon as the customer uses the Goods in a non- acceptance test mode. If the Customer delays acceptance, the outstanding amounts are due thirty (30) days after delivery. INSPECTION & REJECTION OF NONCONFORMING GOODS 6 6.1 Customer shall inspect the packaging the Goods arrive in and if there is visible damage, they shall report this immediately to the freight carrier as well as Hamilton. 6.2 Customer shall inspect the Goods within ten (10) business days after installation (Inspection Period). Customer will be deemed to have inspected the Goods unless it notifies Hamilton in writing of any Nonconforming Goods during the Inspection Period and furnishes such written evidence or other documentation as required by Hamilton. In no event shall any period of time greater than thirty (30) calendar days be considered a reasonable period as set forth above. Nonconforming Goods means only the following: (i) product shipped is different than identified in Customers Purchase Order; or (ii) products label or packaging incorrectly identifies its contents. If Customer timely notifies Hamilton of any Nonconforming Goods, Hamilton shall, in its sole discretion, (i) replace such Nonconforming Goods with conforming Goods, or (ii) credit or refund the purchase price for such Nonconforming Goods, together with any reasonable shipping and handling expenses incurred by Customer in connection therewith. Customer shall ship, at its expense and risk of loss, the Nonconforming Goods, in their original packaging, to Hamiltons facility located at 4970 Energy Way, Reno, Nevada 89502. If Hamilton exercises its option to replace Nonconforming Goods, Hamilton shall, after receiving Customers shipment of Nonconforming Goods, ship to Customer, at Hamilton's expense and risk of loss, the replaced Goods to the Customer at their location. 6.4 Customer acknowledges and agrees that the remedies set forth in Section 6.2 are Customers exclusive remedies for the delivery of Nonconforming Goods. SECURITY INTEREST In order to secure payment for the Goods and as collateral security for the payment of the purchase price of the Goods and any other current or future obligations of the Customer to Hamilton, Customer hereby grants to Hamilton a lien on and security interest in and to all of the right, title and interest of Customer in, to and under the Goods, wherever located, and whether now existing or hereafter arising or acquired from time to time, and in all accessions thereto and replacements or modifications thereof, as well as all proceeds (including insurance proceeds) of the foregoing. The security interest granted under this provision constitutes a purchase money security interest under the Uniform Commercial Code. This security interest will terminate only on the discharge in full of all the payment obligations for purchase of the Goods and all such other obligations of Customer to Hamilton. 6.3 7 ________________________________________________________________________________________________________________________ _ T&Cs Capital December 2018 F-746 Page 1 of 4 8 9 AMENDMENT & MODIFICATION These Terms may only be amended or modified in a writing which specifically states that it amends these Terms and is signed by an authorized representative of each party.

All returned parts which are replaced shall become the property of Hamilton. Hamilton is responsible only for the cost of repair or replacement of defective parts. Hamilton Systems are designed and validated exclusively with CO-RE technology tips. The use of non-Hamilton CO-RE tips on Hamilton Systems shall void Hamilton System performance specifications and warranty.
