Section 1.5 ARC system components and principlesYou shou ld be famili ar with the foll owing componen ts and princ iples before operating the Handheld in a real working environment.

Section 1.5.1 ARC sensors: communications

Section 1.5.1.1 Overview

Every HAMILTON ARC System sensor has two kinds of inter face. These comprise :

Two ana log 4-20 mA interfaces (wit h the exception of the VISIFERM DO ARC, wh ich has one).

One d igita l RS485 Modbus RTU interface.

Analog inter faces

The sensor s two ana log in terfac es are mapped by the factor y in t he fo llowing manner:

mA inter face #1: Parameter 1 (conducti vity, pH, or di ssolved oxygen) . mA inter face #2: Parameter 2 (temperat ure, excep t for the VISIFERM DO ARC).

However, Specia lists can change this mapp ing, i f required .

Final ly, the rela tionship between the values measured by the sensor, and the outpu t sign als fr om the i nterface can also be conf igured.

You can fi nd ou t more about al l thes e aspects of the ana log interf ace in Sect ion 1 .5.6, ARC sensors: analog interface configuration, on Page 1-17.

Analog interface connections between a sensor and a con trol device such as a PLC are always wired .

Figure 1.3 HAMILTON ARC sensor with analog and dig ital interfaces.



Digital RS485 Modbus RTU inter face

The sensor s RS485 Modbus digi tal in terface is used fo r wired connections to ot her ha rdware. An ARC Wi Sensor Adapte r mounted on each ARC sensor i s requ ired for w ireless connect ion, and provides the radio functionali ty. (However, th e sensor a lso requires a separate, wired , powe r supply.)

Section 1.5.1.2 ARC sensor communication with a PLC system

Connection to a PLC system can be by means of the senso rs analog or d igita l interface s, depending on whether the process control system accepts analog or digi tal inputs. If necessary, both digital and ana log i nterfaces can function at the same time.

For reasons of safety, connect ion to a p rocess con trol system is always wired.

Section 1.5.1.3 ARC sensor communication with a Handheld

Senso r communica tion w ith a Handheld is always digi tal. I t can be wired or wi reless. Wired mod e can be use ful for testing , con figur ing, and calibrating sensors outside a p rocess env ironment. Wireless mode (using an ARC Wi Sensor A dapter mounted o n the senso r) is suitable fo r proc ess environments.

Wireless communication be tween the Handheld and the sensors starts automatically when you take the Ha ndheld from its Dock (Figure 1.5).

Section 1.5.1.4 ARC sensor communication with a computer

A computer runn ing the ARC Sensor Configurator freeware i s an altern ative to the Handheld in many respects: it has slightly grea ter f unctionali ty, bu t cannot operate wireless ly.

Senso r commun ication with a computer always takes place by means of the RS485 Modbu s digita l inter face usi ng a wired connection. If you wish to connect a sensor to a compute r, you require bot h a cable to connec t to one of the compute rs USB ports and also an RS485/USB adapter . (For more information, see Appendix A, HAMILTON ARC System components .)

Section 1.5.2 ARC sensors: operator levels

Every ARC sensor always has it s cur rent opera tor level value stored in i ts memory. The ARC System supports three operator leve ls (Table 1.3).

On power-up, eac h sensor falls b ack to the User operator level . This also happens when an opera tor working with the Handheld leaves the password-protec ted area of the Handheld.

When a sensor is set to the User operato r level, it permits only Use r rights to any devic e access ing the data s tored in it s memory, and only User r ights to perform some act ions (Table 1.3).

However, by entering the Admin istra tor o r Speciali st password in t he Handheld, an operator can obtain Administr ator or Speciali st ri ghts (Table 1.3).

For help in correcting an unsatisfactory status, see Section 4.2, Troubleshooting Handheld sensor status colors, on Page 4-2 .

Section 1.5.3.2 ARC Wi Sensor Adapter status colors

NOTE: Sensor Adapter status colors do not have the same meaning as Handheld status colors. For more information, see Section 1.5.3.1, ARC View Handheld status colors .

If a sensor panel has a yellow dot, the sensor it represents has a Warning or Error status. The associated sensor and communications link are functioning, but the sensor reading is possibly compromised. In the picture above, the DO sensor is giving a parameter measurement, but is also sending a Warning status signal. This could be, for example, because the last calibration failed, and the sensor therefore knows its reading is not accurate.You can find more information about an active Warning by going to Screen 34 on Page 3-34: [Sensor] Tools Sensor status, where you can read the warning message.You can find an explanation of all Warning and Error messages in Section 4.4, Warning Messages, on Page 4-3 and Section 4.5, Error Messages, on Page 4-6.

If a sensor panel has a red dot, the sensor it represents has an undefined status. The sensor, the communications link (wireless or wired), or both sensor and link are not functioning at all.

Section 1.5.4 ARC sensors: calibration

Section 1.5.4.1 Introduction

The primary parameter of a sensor can be calibra ted to ensu re the grea test possible measurement accuracy. (The primary pa rameter of a sensor is dissolved oxygen for a DO se nsor, conductivi ty for a Cond sensor, an d so on. Temper ature is the secondary parameter in every ARC sensor, and canno t be calib rated .)

Calib ration offsets the e ffects of t ime and wear on the sensor.

NOTE: Operators can see calibration values for, and Specialists can configure, the primary parameter of a sensor using screens accessed from Screen 29 on Page 3-28: [Sensor] Tools Calibration.

NOTE: Do not confuse calibration with configuration. See Section 1.5.6, ARC sensors: analog interface configuration , on Page 1-17.

Section 1.5.4.2 Calibration procedure

Calib ration of disso lved oxygen and pH ARC sensors takes place at two calib ration points. Calib ration of conductivi ty ARC sensors takes place at just one point. During cal ibrat ion a t each point , sensors are exposed to a def ined and s trict ly-control led environment , and their read ings compensated aga inst the known condi tions of that environment. For example, the VISI FERM DO ARC sensor is ca librat ed:

In an envi ronment of 0% oxygen at it s fir st ca libra tion point . In an envi ronment of atmospher ic oxygen at it s second calibration poin t.

This is shown i n Figure 1.8. Here, the two calibration poin ts are used to const ruct a vir tual curve to plot the luminescence phase shif t (the real parameter underlying the sensor's primary parameter) against t he stated primary pa rameter, namely , dissolved oxygen.

Illuminates green Data is passing between sensor and Handheld.

The sensor is correctly connected and funct ioning normally, and the panel corresponding to the sensor is current ly selected in the Handheld.

Illuminates red There are three conditions in which this can happen:

The ARC View Handheld was switched on a short time ago, and the ARC Wi Sensor Adapter is searching for connected sensors.

The sensor is not functioning. No sensor is connected to the ARC Wi Sensor Adapter.

Sensor Adapter Meaning

Table 1.5 The meaning of status colors on the ARC Wi Sensor Adapter.



This curve is th en used to inter pret luminescence phase shift values during sensor o perat ion, t o give accurate d issolved oxygen measurements.

Other ARC sensors require ca libra tion in different env ironments, and do not always use a curve to interpret the real underl ying parameter (the pH sensor uses a straight -line virtu al graph). Never theless, the principles for the calibra tion o f the primary parameter are the same for all ARC senso rs.

NOTE: If calibration fails at one of the calibration points and a corresponding warning message is generated, this does not necessarily mean that the sensor cannot be used. In event of failure at a calibration point, the sensor uses its most recent successful calibration data for that point. Operators can see the Quality Indicator in Screen 14 on Page 3-8: [Sensor] View Sensor status.

Section 1.5.5.2 Modbus device addresses

Background

Modbus is a dig ital serial communica tions protocol publi shed by Modicon for use w ith it s programmab le logic contro llers (PLCs). I t has become a stand ard commun ications p rotocol, an d is now the most commonly available means of connec ting industrial elec tronic dev ices.

Modbus all ows f or com munication between many d evices connected to the same n etwork, for examp le, a syste m tha t measures temperatu re and hum idity and commun icates the resu lts t o a compu ter.

HAMILTON u se a Modbus pro tocol in wh ich there is one mas ter device (the PLC or ARC View Handheld) and numerous passive slave devices ( the sensors). The master device transmit s a Modbus dev ice address to estab lish a communica tions link with a sensor. All sensors that do not have this address ign ore the transmission .

The HAMILTON Modbus protocol i s described in detai l in the VISIFERMTM DO Modbus RTU Programmers Manual, PN 624179.

Modbus device addresses and sensors

An ARC sensors Modb us device address un iquely identifi es an ARC senso r with respect to it s digit al commu nicat ions wit h the PLC. The address is represented by a number in the range 1 to 30.

NOTE: Do not confuse the Modbus device address of a sensor with its Sensor ID or Sensor Number. For more information about Sensor IDs or Sensor Numbers, see: Fig ure 1.2 , The ARC View Handheld showing top level of interface, pH sensor

attached).. Tab le 1.1 , ARC View Handheld keys and interface. .

By def ault, every ARC sensor has a Modbus devi ce address of 1. This is set at the factory du ring the sensor s product ion. Because of this , a new Modbus device address (in ot her words, not 1) must be configured for every ARC sensor t hat i s added to an ARC System with a dig ital P LC, thereby making sure t hat every sensor in the Sys tem has a unique address. (If two sensors have the same address, then when the PLC transmits an address , only the quicker of the two sensors responds).

Section 1.5.5.3 Baud rates

The Baud rate a ffects the wired connection mad e by an ARC sensors RS48 5 Modbus d igita l inter face. It has no influ ence on the ana log connect ion between a sensor and an analog PLC system. It is th erefo re on ly cr itica l for wired connections between ARC sensors an d dig ital PLC systems.

Naturally, higher Bau d rates equate to qu icker communica tions between sensors and othe r hardware. However, h igher Baud rates can lead to unreli able connections in some instances. A typical example of this is a long cab le connection between a sensor and a digita l PLC system. It is not possib le to be specif ic about cable lengths or to o ffer recommenda tions , because variables such as cable qualit y and loca l inte rferen ce are as important as cabl e length.

If you have an d igita l PLC system, you mus t exper iment to find the bes t combination of speed and reliabilit y.



Section 1.5.6 ARC sensors: analog interface configuration

NOTE: Specialists configure the analog interface using screens accessed from Screen 35 on Page 3-34: [Sensor] Tools Interface configuration.


All ARC sensors have two analog interf aces (w ith the exception of the VISIFERM DO ARC, which has one). N ormal ly, yo u use one analog inter face for on e measurement par amete r. For exam ple, by de fault , the Easy ferm Plus s ensor uses mA inter face #1 for its primary pa rameter (pH ) and mA inter face #2 for its secondary parameter (temperatu re).

However, you do not have to keep the defaul t sett ings. You might even want to map the senso rs primary paramete r to b oth an alog inter faces . You could then conf igure each inte rface diffe rentl y, for example, op timiz ing mA inter face #1 for pH readings be tween pH 3 and pH 4, and opti mizing mA inter face #2 for read ings between pH 6 and pH 7.

You can configu re each of a sensors ana log interf aces indep enden tly.

NOTE: Analog interface configuration is for both of a sensors parameters. Sensor calibration (for measurement accuracy) is for only a sensors primary parameter. (See Section 1.5.4, ARC sensors: calibration , on Page 14).

There are four a spects to configu ring an ana log in terface:

Selec ting the inter face/parameter combina tion. (Sectio n 1.5.6 .2, Mapping parameters to the analog interfaces).

Selec ting the in terface mode fo r the inte rface and p arameter selected. (Sectio n 1.5.6 .3, Configuring the mode of the analog interfaces ).

Configuring the output current for the interfa ce mode. (Section 1.5.6.4, Configuring the output current of the analog interfaces).

Configuring Errors and Warnings for the interf ace mode. (Sect ion 1.5. 6.5, Configuring Errors and Warnings).

Section 1.5.6.2 Mapping parameters to the analog interfaces

Specialist s firs t defi ne the inter face/parameter combination to they will configure. Remem ber th at pH and conducti vity sensors have two analog inter faces , dissol ved oxyg en senso rs, only one. This means that for pH and conducti vity senso rs, there are two in terface/parameter combinat ions to configure.

Section 1.5.6.3 Configuring the mode of the analog interfaces

Introduct ion

Each analog interface can be switched on and off. An ac tive inter face can operate in t wo ways:

Measuremen ts: The ou tput of the 4-20 mA in terface is a func tion of the measurement parameter.

Test: The outpu t of the 4-20 mA inter face is a constan t signal . This cou ld be used , for example fo r tes ting of the 4-20 mA current loop.

NOTE: Specialists choose the operation mode on Screen 40 on Page 3-38: [Sensor] Tools Interface configuration mA interface #1 [or #2] Interface mode.

Configuration

In reality, choice of senso r ana log interface mode requires that a number of f urther cho ices m ust be made by the Specialist . These are discussed in Sectio n 1.5 .6.4.

Section 1.5.6.4 Configuring the output current of the analog interfaces

Introduct ion

Specialist s can configure t he way in which each analog inter face of the senso r sends info rmation to the PLC system. Spec ialis ts do thi s by defining the relationship between the value measured by the sensor (for instance, the pH 7) , and the e lectri c cur rent transmitted to the PLC system (for instance, 10 mA).

NOTE: Specialists configure the analog interface ou tput current starting on Screen 40 on Page 3-38: [Sensor] Tools Interface configuration mA interface #1 [or #2] Interface mode.

Configuration

The Specia list has al ready decided on the opera tion mode o f the inte rface:

Measuremen t. Test.

(This is d iscussed in Sec tion 1.5.6. 3, Configuring the mode of the analog interfaces).

If the Specialist is using the inte rface for measurements, he can decide whe ther the relati onship between the measured value and the outpu t current is to be determined by two po ints as a str aight -line grap h, or by three poin ts as a two-stra ight- line graph. These options are called 420 mA linear , and 420 mA in terface bili near, and are explain ed in Table 1.6, Explanation of interface modes configured on Screen 40 on Page 3-38.

Alternatively, the Special ist can choose the test mode. This is ca lled 420 mA fixed, and is also shown in Table 1.6, Explanation of interface modes configured on Screen 40 on Page 3-38.

If the Speciali st is not using a test mode, he now conf igures values for the relationship (linear or bilinear) he has selected . If he is using a test mode, h e can defi ne va lue for the tes t mode.



NOTE: The Specialist configures values on Screen 41 on Page 3-39: [Sensor] Tools Interface configuration mA interface #1 [or #2] Output current configuration.

The task o f the Spec ialis t is t o con figure the senso r signal sent to the analog PLC in a way that emphasizes the measurement range th at is of most in terest . For instance, if the pH in the process is always in the range pH 4 to pH 6 , then the Spec ialist conf igures the signal fo r this range, and allows measurement values outs ide pH 4 to pH 6 to fall out of 4-20 mA range o f the analog inter face.

Mode Explanation

OFF The analog interface is switched off. No signals are sent.

420 mA fixed The interface sends a continuous fixed signal fo r test purposes.

NOTE: Specialists can configure this fixed test signal on Screen 41 on Page 3-39: [Sensor] Tools Interface configuration mA interface #1 [or #2] Output current configuration.

420 mA linear Configuration of the interface takes place using two points. In this kind of configuration, the two points become the ends of a straight-line graph that determines the relationship between:

The value measured by the sensor immersed in the process, for instance, the DO value.

The output of the 4-20 mA interface to the process control system.

The figure above shows two virtual straight-line g raphs expressing the relationship between measurements on the VISIFERM DO ARC sensor, and interfaces output current. The graphs are for dissolved oxygen and for temperature. (Both parameters cannot be mapped to the single analog interface at the same time.)

NOTE: Specialists can enter a value for each end of the graph on Screen 41 on Page 3-39: [Sensor] Tools Interface configuration mA interface #1 [or #2] Output current configuration.

NOTE: Specialists configure Errors and Warnings on Screen 42 on Page 3-41: [Sensor] Tools Interface configuration mA interface #1 Error/Warning configuration.

Section 1.5.7 ARC sensors: Cleanings and Sterilizations In Place

Clean ings In Place (CIPs) and Steri lizat ions In Place (SIPs) are both s uppor ted by the ARC System.

NOTE: All operators can see, and Specialists can configure, the definitions and total number of CIPs and SIPs for a sensor. They do this Screen 26 on Page 3-26: [Sensor] Tools Measurement CIP/SIP definition.

As the name suggests , a CIP and SIP are the events in wh ich a sensor is cleaned and sterilized without removing it from the process equipment. A typica l defin ition for a CIP and a SIP are shown below:

Every ARC sensor automati cally coun ts the number o f CIPs and SIPs it ha s undergone, and records the totals internally. Depending on whether an at tempted CIP or S IP meets i ts ta rget parameters , the senso r determines the attempted CIP or S IP to have taken place or not. Figure 1.9, on Page 1-21 shows sensor recordings for the CIPs and SIPs defined in Tab le 1.7.

Point 1: The sensor does not record a S IP because the time durat ion was too short to meet the definit ion o f a S IP shown in Tab le 1.7.

Point 2: The sensor reco rds a CIP b ecause the time and tempe rature were in range.

Point 3: The sensor does not record a C IP because the tempe rature cont inues to ri se above the upper maximum for a CIP. Instead, the SIP at Point 4 is reco rded.

Point 4: The sensor reco rds a SIP because the time and temperatu re were in range.

Both CIPs and SIPs are wearing the sensors , and are the main cause for the l imited sensor life of senso rs from al l manufacturers . Typ ically, sensors can withs tand 5 0 to 100 CIPs and SIPs, depending on the temperature and tim e duration of the events, and a lso depend ing on whether clean ing and sterili zation agents a re used.

With experience, opera tors can combine t he informat ion found on Scree n 26 about the number o f CIPs and SIPs that a sensor has undergone, together with the ir know ledge of the kind of CIPs and SIPs used, to estimate the remaining life-span of their sensors.

Section 1.5.8 ARC sensor measurements: moving average

A moving avera ge is a win dow dur ing whi ch a sensor looks back wards in time, averag ing its latest reading wi thin the w indow. The use of averaged readings can be preferable when real readings fluctuate greatly . This is because an ave raged reading is a bet ter ind icatio n of an underly ing trend than are many, variable readings.

NOTE: A Speciali st se ts the mov ing average for a sensor on Sc reen 24 on Page 3-23: [Sensor] Tools Measurement.

Do not co nfu se a r ead ing (o f whic h t her e c an be man y i n a mo vin g a ver age ) wit h the resol uti on valu e (V ISI FER M DO ARC only). Resolu tio n is exp lai ned in Sec tio n 1 .5.9, ARC sensor measurements: resolution.

Mov ing av era ges are e xplain ed in gre at det ail in the VISIFERMTM DO Modbus RTU Programmers Manual, P N 624 179 .

A moving average improves signal stabili ty over the shor t term. Howeve r, the response time of the senso r inc reases (degrades ) with the increased moving average. For examp le, V ISIFERM DO ARC calcu lates a new oxygen reading every three seconds. You can smooth this reading by means of a movi ng average (Fi gure 1.10, on Page 1-22) . Howev er, a mov ing ave rage applied to 20 thre e-second readings resul ts in a resp onse time of at leas t 60 seconds. The Special ist ca n set the number of readings i n the moving average array between 1 and 16 (pH and conductiv ity sensors) , or 1 and 30 (DO senso r), or can enter a va lue of zero (0 ) to ac tivate the automatic mod e, in wh ich the sensor vari es th is se tting depending on the measuri ng signal trend .

Section 1.5.9 ARC sensor measurements: resolution

With respec t to ARC sensor measurements, t he expression resolution refers to the number of sub-measu remen ts underlying a recorded measurement made by the VISIFERM DO ARC sensor. The expression is not used w ith any other kind of sensor, and the Resolution field is onl y avai lable on the Handheld for d issolved oxygen sensors.

NOTE: The Speciali st sets the resolution for a VISIFERM DO ARC sensor on Screen 24 on Page 3-23: [Sensor] Tools Measurement.

The measurement made by VISIFERM DO ARC in each 3-second inte rval is, in reality, the average of up to 16 sub-measurements (F igure 1.11, on Page 1-23) . The Spec ialis ts can set the number of

sub-measurements between 1 and 16, or can enter a value of zero (0) to acti vate the au tomat ic mode, in which the sensor varies th is se tting depending on the measuring signal trend.

The advantage of using a lower reso lution is the shor ter pe riod o f exposure o f the l uminophore to the exci tation light. Thi s reduces the photo bleaching of the luminophore and enhances its lifet ime, and therefore the lif etime of the sensor. The advantage o f usin g a hi gher resolution is enhanced signa l qua lity.

Section 1.5.10 ARC sensor measurements: temperature compensation factor

With res pect to ARC sensor measurements, the exp ressio n temperature compensation factor refers to an adjustment tha t an Specialist can make to compare the conductivi ty measurements at diffe rent temperatures. It provide s an estima te of the samp les conducti vity at a common refe rence tempe rature (25C ). The Temp. comp. factor field is available on the Handheld for conductivi ty sensors only .

The temperature compensat ion factor i s the rate at whi ch a solutions conduc tivit y incr eases with an increase of temperature and is expressed as the percentage inc rease of conduct ivity for a tempe rature rise of 1 C. The compensation factor chosen by the Specialist must be depe ndent on the l iquid being mon itored by the sensor .

Section 1.5.11 ARC sensor measurements: Quality Indicator

With respec t to AR C sensor measurements, the ex press ion Quality Indicator refers to an esti mate made by the sensor o f the accuracy and reliab ility of i ts pri mary reading: conduc tivit y, pH , or disso lved oxygen (not temp eratu re, whi ch is the secondary reading) . The Quality Indicatorfield is available for al l ARC sensors an d rep resen ts the senso r condition in s ix gradations: Excellent, High, Acceptable, Poor, Very Poor, Defective.

NOTE: All operators can see the Quality Indicator for a measurement on Screen 14 on Page 3-8: [Sensor] View Sensor status.

The calcula tion o f the Quali ty Ind icato r for a sensor takes i nto consideration a n umber of factors, some senso r-specific, and some genera l. Sensor-speci fic co nside rations include:

Disso lved oxygen sensors: luminophore status is continuously moni tored .

pH sensors : 0 ( zero) poin t pos ition and s lope of the pH graph is ch ecked foll owing calib ration.

Conductivi ty sensors : Cel l constant of the sensor is checked follo wing calib ration.

General consider ations for the calcu lation of the Qualit y Ind icato r inc lude:

The qualit y of the most recent calibration. If a calib ration fails at one of the ca libra tion po ints and a calibration warning message is generated, this does not necessarily mean that the sensor cannot be used. In event of fail ure at a calibration point, the sensor use s its most recent successful cal ibrat ion data, but the Quality Indicator can degrade.

Because the accuracy and r eliab ility of a ll sensors can decli ne wi th use: The number of C leanings In Place (C IPs) the sensor has underg one. The number of S teril izations In Place (S IPs) the sensor has underg one. The number of operat ing hours at dif feren t temperatures.

The HAMIL TON ARC System supports three kinds of operator: User, Administ rator, and Special ist. To read more about this, s ee Section 1.5.2, ARC sensors: operator levels, on Page 1-11.

The User has the lowest level of access to the ARC System of all operat or types: he or she can only check the status of the System, and read measurements made by sensors in the Syste m.

Task 1 Checking the status of all sensors in the ARC system

Introduction

The Handheld can display data from only the four (or fewer) sens ors that it activel y monito rs at any time. Data from each of these sensors is shown in a data-overv iew panel conta ining infor matio n about sensor type, pa rameters and va lues measured, and s ensor status. I f eve rything is funct ioning corr ectly , the status symbol is green (Figure 2.1).

Task 2 Calibrating a sensor

Int roduct ion

When you calibrate a senso r, you cal ibrate the senso rs pr imary measurement pa rameter (dissolved oxygen, conduc tivit y, pH and s o on) . You cannot ca librat e the senso rs secondary measu remen t parameter, tempera ture.

The ARC System applies an automatic calibration (AC) procedure and enables you, the Admin istrat or, to ea sily ca librat e senso rs. AC ut ilizes a micro processor wi thin the senso r to adju st the measurements to the va lues of the corresponding standa rds. The AC options availab le depend on sensor type (pH, conductivit y, or DO).

Cal ibration

Calib ration is a t wo-sta ge procedure for p H and d issolved oxygen (DO) sensors , and a one-s tage procedure for conduc tivit y sensors:

pH and DO: calibration at data -poin t 1, f ollowed by calib ration at data-point 2. Conductivi ty: calibration at data-point 1 only .



You must apply the required conditions a t each cal ibrat ion point. This means app lying two appropriate pH so lutions for a pH sensor, t he two requir ed oxygen levels for a DO sensor, and an appropriate cal ibrat ion solution fo r the cond uctiv ity sensor .

HAMILTOM ARC pH and conductivi ty sensors have an auto-ca librat e function , by which they automatica lly recogn ize the recomme nded HAMILTON calibra tion standard in which they are immersed. This means tha t you can choose from one of a range of HAMILTON stand ards fo r both data-point 1 and data -poin t 2 cal ibrat ion, and the sensor automatica lly calibrates appropriately.

NOTE: You can find more sensor-specific information in the documentation that accompanies your ARC sensors.

Act ions

1. Selec t the requ ired sensor on the top level o f the Handhelds interface.

2. If necessary, enter the Administrator password as descr ibed in Task 1, Setting the Administrator operator level , on Page 2-5.

3. Go to Calibration Calibrate.You see a screen showing the two opti ons for ca libra tion (for conductivi ty sensors , only one), and the corresponding va lues for calibration standards from the last successful calib ration event. For example , for the pH sensor, you see:

This informs you tha t for optim al accuracy you must perform the fir st stage o f the calib ration with the senso r in an env ironment of pH 4.01, and the second stage of the calibration with the sensor in an env ironment o f pH 7.00.

4. Apply the correc t condit ions (oxygen level or standard) to the senso r for calib ration at data-point 1.

5. Click Calibration data point 1.The f irst stage of the ca libra tion t akes place .

6. Apply the correc t condit ions (oxygen level or standard) to the senso r for calib ration at data-point 2.

7. Click Calibration data point 2.The second stage of the calibration takes place.

NOTE: If calibration fails at one of the calibration points, this does not mean that the sensor cannot be used. In event of failure at a calibration point, the sensor uses its most recent successful calibration data for that point. Operators can see the Quality Indicator in Screen 14 on Page 3-8: [Sensor] View Sensor status.

You can fi nd more in formation a bout calib ration on Screen 33 on Page 3-32: [Sensor] Tools Calibration Calibrate.

Calibration point 1 4.01pH

Calibration point 2 7.00pH

Task 2 Adding or exchanging a sensor in an ARC system

As a Specialist , your job includes setting up and configuring elements of the ARC Syste m. The most common task is adding or exchanging a sensor. This breaks down into the following sub-tasks .



Sub-Task 2.1 Entering the Sensor ID

NOTE: Thi s s ub- tas k i s r ecomme nde d w hen yo u a dd an ARC se nso r t o a n A RC Sys tem .

Thi s s ub- tas k c onc erns o nly the s ens or s d igi tal in ter fac e.

Every sensor in an ARC System has a numb er of iden tifie rs. These include:

The p roduc t name, fo r inst ance VISIFERM DO ARC. The f irmware ve rsion of the code included in t he sensor. The sensor s pa rt number. The sensor s serial number. The sensor s Modbus device add ress.

All oper ators can see these fields on Screen 16 on Page 3-12: [Sensor] View Sensor info.

Most of these id entifi ers ar e set in the fac tory, and cannot be changed. However, Spec ialis ts can change the Sensor ID . By defau lt, this s tring contains the sensor s part number followed by the senso rs serial number. It is o ften helpful to enter a st ring in thi s fie ld tha t iden tifies the senso r in the con text of your ARC System environment . For example, the stri ng Process C3might enable other operators to quickly identify the sensor within your p roces s envi ronment.

NOTE: The Sensor ID is held in memory in the sensor. Every time you exchange a sensor for a new one, always check the ID Sensor string in the new sensor.

You can fi nd in forma tion about changing the Sensor ID in Screen 36 on Page 3-35: [Sensor] Tools Sensor info.

Sub-Task 2.2 Configuring the Modbus device address

NOTE: Thi s s ub- tas k i s m and ato ry whe n y ou add an AR C s ens or to a d igi tal PL C sys tem .


An ARC sensors Modbus dev ice addr ess uniq uely identifi es an ARC sensor with in a group of ARC senso rs wi th respect to it s dig ital c ommun ications w ith a digi tal PLC system. (However, it has no effec t on communicat ions with the ARC View Handheld, or with the connection to the 4-20 mA analog interface.)

It is recommend ed, that every senso r in an ARC Sys tem must have a unique Modbus device address. You can read more about Modbus device addresses in Secti on 1.5.5.2 , Modbus device addresses, on Page 1-16.

You can fi nd in forma tion about sett ing th e Modbus device address for a senso r in Screen 37 on Page 3-36: [Sensor] Tools Interface configuration Digital RS485.

Sub-Task 2.3 Configuring the Baud rate

NOTE: Thi s sub- tas k i s reco mme nde d when you add an ARC senso r to a d igi tal PLC sys tem .




The Baud rate a ffects the wired connection mad e by an ARC sensors RS 485 M odbus digi tal inter face. It has no influ ence on ei ther wireless o r ana log connec tion of a sensor.

You can read mo re about Baud rates in Section 1.5.5.3, Baud rates, on Page 1-16.

You can fi nd in forma tion about sett ing th e Baud rate for a sensor in Sc reen 37 on Page 3-36: [Sensor] Tools Interface configuration Digital RS485.

Sub-Task 2.4 Configuring the analog interface

NOTE: Thi s s ub- tas k i s necessary when the sensor is connec ted to an analog PLC system.

Thi s s ub- tas k c onc erns o nly the s ens or s a nal og int erf ace .

By configuring the ARC sensor s ana log interf ace, you make i t able to map a measured value to the 4-20 mA standard in terface. Con figura tion op tions for the ana log interface are quite extens ive, and a re explained in deta il in Sect ion 1 .5.6.3, Configuring the mode of the analog interfaces.

If you are not using the analog connection it is recommended to switch the analog interface off .

You can fi nd in formation about conf iguring the ana log i nterface o f a sensor in Screen 38 on Page 3-36: [Sensor] Tools Interface configuration mA interface #1.

Sub-Task 2.5 Configuring a calibration procedure

The ARC View Handheld util izes an au tomat ic ca libra tion procedure with prede fined set of calib ration standards where you canno t defi ne the detai ls or p erform a manual ca librat ion a t user speci fic s tandard. For exa mple, for a dissolved oxygen sensor , you could not deter mine that the first stage o f the cal ibrat ion (Calibration data point 1) should be at 10% oxyge n, and the second stage (Calibration data point 2) should be at 90% oxygen.

However, you can conf igure calibra tion and perform the manual procedures using the ARC Sensor Configurator freeware.
