Safety Summary

GENERALWARNINGS

Equipment EnvironmentAll components, whether in transportation, operation or storage,must be in a noncorrosive environment.

Electrical Shock Hazard During MaintenanceDisconnect power or take precautions to insure that contact withenergized parts is avoided when servicing.

SPECIFICWARNINGS

Use this equipment only in those classes of hazardous locationslisted on the nameplate. Uses in other hazardous locations can leadto unsafe conditions that can injure personnel and damage equip-ment. (p. 3-3)

Do not apply power until completing all setup and physical installa-tion and wiring connection and cabling procedures. Applying powerbefore completing these procedures exposes personnel to seriousinjury from electric shock. (p. 3-4)

Keep the enclosure and covers in place after completing the wiringprocedures and during normal operation. Do not disconnect or con-nect wiring or remove or insert printed circuit boards unless powerhas been removed and the flammable atmosphere is known NOT tobe present. These procedures are not considered normal operation.The enclosure prevents operator access to energized componentsand to those that can cause ignition capable arcs. Failure to followthis warning can lead to unsafe conditions that can injure personneland damage equipment. (p. 3-4)

Disconnect the AC line cord or power lines from the operatingbranch circuit coming from the source before attempting electricalconnections. Instruments powered by AC line voltage constitute apotential for personnel injury due to electric shock. (p. 3-17)

Place the equipment in the MANUAL mode before performing thisprocedure. During this procedure, the equipment executes theuser-entered configuration. The MANUAL mode locks out otherequipment and prevents accidental engagement of that equipmentthat can upset the process. Some process upsets can injure per-sonnel and damage equipment. (p. 6-2, 6-5, 6-12)

Secure the process before performing this procedure. Performingthis procedure while the equipment is in the process can upset thatprocess. Some process upsets can injure personnel and damageequipment. (p. 9-1)

Safety Summary (continued)

SPECIFICWARNINGS

(continued)

Allow only qualified personnel (refer to INTENDED USER) to com-mission, operate, service or repair this equipment. Failure to followthe procedures described in this instruction or the instructions pro-vided with related equipment can result in an unsafe condition thatcan injure personnel and damage equipment. (p. 9-2)

Acids and bases can cause severe burns. Use hand and eye pro-tection when handling. (p. 9-2)

Store the solution in a suitable container. Label it as containing anextremely flammable strong acid. Use extreme care when handling.Failure to follow this warning can injure personnel and damageequipment. (p. 9-3)

Do not substitute components that compromise the certificationslisted on the nameplate. Invalidating the certifications can lead tounsafe conditions that can injure personnel and damage equipment.(p. 11-1)

Do not disconnect equipment unless power has been switched offat the source or the area is known to be nonhazardous. Disconnect-ing equipment in a hazardous location with source power on canproduce an ignition capable arc that can injure personnel and dam-age equipment. (p. 11-1)

SPECIFICCAUTIONS

Do not overtighten screws. This may cause the gasket to seat incor-rectly and a watertight seal will not be obtained. This could violatethe NEMA 4X rating and damage the circuitry. (p. 3-12)

To prevent possible signal degradation, a separate metal conduitrun is recommended for the sensor cable. (p. 3-15)

Auto/Solution pH can only be used for processes that are extremelyrepeatable in both pH values measured and chemical constituentspresent. (p. 4-5)

When measuring the pH of a grab or lab sample, make sure that thetemperature of the sample is compensated. In some cases, the pHof the solution may change value as the sample cools. Grab sam-ples should not be left open to the atmosphere. Samples maychange or deteriorate as time passes. It is important to measuregrab samples as soon as they are taken. (p. 6-3)

SECTION 1 - INTRODUCTION

OVERVIEW

The TBI-Bailey µFact Series instrumentation displays and con-trols the pH of process fluid streams. The Type TB701 analyzerhas a number of user-selectable features that optimize mea-surement of pH. Both the process variable and temperatureare measured and displayed. Temperature compensation forpH can be formatted in three ways: Manual, automatic andauto-solution.

Recorder/data outputs can be selected to represent a numberof variables including pH, controller output, temperature andraw pH (no solution temperature compensation). All outputsare separately scalable and are defined by simple prompts onthe configuration screen.

Digital outputs can be configured to a number of parameters,for example, as high or low set points for the measured processvariable; as temperature with adjustable hysteresis and timedelay functions; as a timer for time relay activation; or as per-cent PID output (exceeded).

Digital outputs can also be used in a cycle timer applicationoperating as a high or low set point. As the set point isexceeded, the timer begins timing for a fixed duty cycle. As longas the process exceeds the set point, the timer will reset itselfat the end of each duty cycle. The relay will activate at thebeginning of each cycle for a fixed percentage of the duty cycle.The set point, duty cycle, time and percent on time are all tun-able.

An integral PID controller can be activated through simple pro-gramming prompts. Three types of control output are avail-able: Four to 20 milliamps or zero to 20 milliamps, pulsefrequency adjustable to a maximum of 120 pulses per minuteand pulse duration adjustable to a maximum 60-second dura-tion cycle.

A simple five-segment function generator can be entered forcharacterization of pH titration curves to enable adaptive con-trol of nonlinear processes.

A bidirectional controller with two control set points for controlof both acid and base addition is also available with an integralPID controller. The derivative function is not available on thebidirectional controller.

INTRODUCTION

This section provides information on analyzer functionalityand capabilities, an operational block diagram, and importantinformation for configuration, calibration and operation of theanalyzer. It also contains an operator interface controlsdescription, a description of the main menu and the processdisplay and the information for entering and exiting from thesescreens.

ANALYZER CONFIGURATION OVERVIEW

There are three types of configurations from which to choose:Basic analyzer, PID controller or bidirectional controller. Afterselecting, the configuration can be customized to meet therequirements of a specific application. This section detailsthese options.

Basic Analyzer Transmitter

The basic analyzer transmitter configuration provides a meansby which to monitor and control the pH of a process fluid. Con-trol of the final element is achieved by using the relay outputsin either a simple ON/OFF or ON/OFF cycle timer mode. Referto ANALOG OUTPUTS and RELAY OUTPUTS for additionalinformation. The analog outputs in this configuration are dedi-cated for recorder outputs. The process display shows the pHinput, process temperature, user-specified set points and ana-log output.

PID Controller

The PID controller configuration provides the functionalityand flexibility of the basic analyzer transmitter configurationplus the capability of single channel PID control with optionallinearization of pH titration curve. Refer to Appendix A. Con-trol of the final elements is achieved by using an analog out-put and/or by using the relay outputs in a time proportional,frequency proportional, ON/OFF, or ON/OFF cycle timermode. Recorder outputs are also available in this configura-tion. The process display shows the process variable, processtemperature, PID set point and PID control output.

Bidirectional Controller

The bidirectional controller configuration provides the func-tionality and flexibility of the basic analyzer transmitter config-uration plus the capability of dual output PI control withoptional linearization of the pH titration curve. Refer toAppendix A for addition of both acid and base. Control of thefinal elements is achieved by using analog outputs or by usingthe relay outputs in a time proportional or frequency propor-tional mode. Recorder outputs are also available in this config-uration. The process display shows the process variable, setpoints, process temperature, and control outputs.

NOTE: The bidirectional controller does not have derivative action.

TEMPERATURE COMPENSATION

Temperature has two effects on pH measurement. The firsteffect, commonly referred to as the Nernstian effect, is thatincreasing temperature increases the voltage produced by a pHsensor at all pH values other than the thermo-isopotentialpoint of the sensor (the point where the sensor output is notaffected by temperature). The second effect of temperature onpH measurement is on the actual solution pH. This effect can-not be given a general mathematical description. It is differentfor every solution and the pH value of every solution.

Three types of temperature compensation are available:

1. Manual - for Nernstian effects at a specific fixed temper-ature.

2. Automatic - for Nernstian effects at any temperature.

3. Auto-solution - for both Nernstian and solution effects.Standard automatic and automatic solution require a 3-kilohmBalco RTD input. This device is available with the TBI-BaileypH sensor or as a separate device.

DAMPING

Damping can be helpful in noisy process environments. Damp-ing can be added to the input pH signal or to the pH signal thatgoes to the recorder output. Damping is added as a capacitive

type lag where reaction to any signal change is slowed accord-ing to a time constant entered. Five seconds of damping willallow reaction to approximately 63 percent of a step changeover the five-second period. Choices available for damping arenone, pH input and recorder.

Damping the pH input will cause signals to the controller, relayoutput set point alarms and recorder output to be damped.Damping the recorder output affects only the recorder pH out-put. Both choices can be set separately. Damping both choiceswill cause double damping on the recorder output. Damptime is adjustable from 0.0 to 99.99 seconds.

The bidirectional controller configuration defaults to pH inputdamping of 1.0 second. This is advised for most process appli-cations. Processes having both quick and large erratic changesin process pH may require additional damping for proper con-trol. Basic analyzer and single PID controller configurationsdefault damping to NONE.

ANALOG OUTPUTS

There are several modes in which the analog outputs canoperate. The mode is determined by the configuration chosen.

The analyzer has two standard and one optional analog out-puts. These outputs can be either a voltage or current type,direct or reverse acting. The choices are four to 20/zero to 20milliamps or one to five/zero to five VDC. Refer to SELECTINGOPTIONS in Section 3 to determine proper jumper settings forvoltage or current operation. All of the outputs are separatelyscalable, and all the outputs are isolated from the input.

The analog outputs are available for transmitting processinformation to recorders, data loggers, control systems, valves,etc. The information transmitted can represent (be sourced to)process pH or temperature. The outputs can be ranged acrossany portion of the particular measurement range by program-ming the lower limit represented by zero milliamps/zero voltsor four milliamps/one volt, and the upper limit representedby 20 milliamps/five volts (Figure 2-1).

Recorder Outputs

In the basic analyzer transmitter, the analog outputs are dedi-cated as recorder outputs. In the PID controller and bidirec-tional controller, the analog outputs may be used as recorderoutputs as well by connecting them in series with the controldevice and recorder. Variables that can be tied to these outputsin this mode include pH, controller output and temperature.The analog output on the alarm expansion board adds raw pH(no solution compensation) as a source.

ANALYZER FUNCTIONALITY AND OPERATOR INTERFACE CONTROLS

2 - 4 I-E67-43-1A

Control Outputs

In either the PID controller or the bidirectional controller con-figuration, either the analog or digital outputs may be used tocontrol a final control element.

RELAY OUTPUTS

The analyzer has two standard and two optional relay outputs(Form C, SPDT relays) that are completely programmable.

Use the programmable relay outputs (DO1 through DO4) for:

• Process control by connecting them to solenoid or controlvalves or other control devices.

• Alarm notification.

• Timing.

High or Low Set Point

The example shown in Figure 2-2 illustrates a high set point of10.0 pH with a hysteresis of 0.1 pH. The relay activates at 10.0pH and deactivates when process pH drops below 9.9 pH. Thesecond half of the figure shows the same situation with a15-second time delay before the high set point relay activates.Set point action is programmable as high or low action. Setpoint hysteresis and time delay are tunable.

High or Low Cycle Timer

The example shown in Figure 2-3 illustrates the cycle timeroperating as a high set point. As the set point is exceeded, thetimer begins timing for a fixed duty cycle. As long as the pro-cess exceeds the set point, the timer will reset itself at the endof each duty cycle. The relay will activate at the beginning ofeach cycle for a fixed percentage of the duty cycle. The setpoint, duty cycle time and percent on time are all tunable.

Washer Timer

Automatic cleaning of sensors can be accomplished by pro-gramming relay output four (DO4) as a sensor cleaner(Figure 2-6). At prescribed time intervals (cycle time), DO4 willactivate, thus allowing a cleaning solution to be sprayed on thesensor for a secondary time segment (clean time). Controlleroutputs are held constant during the cleaning period (cleantime) and for the time it takes the cleaning solution to dissipate(recovery time). Recorder outputs can be frozen during thecleaning and recovery times (Hold Outputs, YES or NO). Allother relay outputs revert to logic zero for the duration of theclean and recovery times.

ALARMS

The analyzer alarms certain process conditions by printingALARM on the process display. It also designates the lower leftsoft key as an ALARM ACK (alarm acknowledge) key. The alarmmessage remains on the process display until the conditionclears. The ALARM ACK message disappears when the appro-priate key is pressed. An ALARM SUM (alarm summary) todescribe what condition caused the alarm is accessiblethrough the soft keys. Diagnostic errors, overrange pH andhigh or low temperature all cause alarms. Individual relay out-puts can also be programmed to indicate measurement looperrors particular to the type of analyzer and sensor application.

The process temperature alarm points are preset at -20 degreesand +150 degrees Centigrade (-4 degrees and +302 degreesFahrenheit). These values can be adjusted for a particular appli-cation. For the PID and the bidirectional controllers, the processvariable, pH, high and low alarm points are user-selected.

The analyzer performs a number of diagnostic checks thatindicate faults in the measurement loop. Most of these diag-nostics are exhibited as alarm display messages. These mes-sages are accessible through ALARM SUM on the soft keymenu.

Refer to Section 8 and Section 9 for additional information ondiagnostic capabilities of the analyzer.

WATCHDOG TIMER/FAILURE DETECTION

The analyzer continually runs a set of self-diagnostics toinsure proper operation. Jumper J10 on the main board allowsa choice of the response of the analyzer upon detection of anon-board failure. A fail-safe setting causes the relay outputs tode-energize and the analog outputs go to zero volts or zero mil-liamps. An automatic reset setting causes the analyzer to resetitself in an attempt to resolve the failure and come up running.Refer to Section 3 to set the jumper.

SECTION 3 - INSTALLATION

INTRODUCTION

This section covers special handling, unpacking and inspec-tion, location considerations and safety considerations. Setupand physical installation, jumper settings, mounting, wiringconnections and cabling, and preoperating adjustments arealso included.

After mounting the analyzer, continue with the instructions forAC power wiring, analog and digital I/O wiring and grounding.

SPECIAL HANDLING

In addition to the normal precautions for storage and handlingof electronic equipment, the Type TB701 analyzer has specialstatic sensitive device (SSD) handling requirements. Thisequipment contains semiconductors that can be damaged fromdischarges of static electricity. Therefore, do not touch thecomponents on the circuit board if possible. Ordinarily, no cir-cuit damage results from handling the circuit board by theedges.

To minimize the chances of damage by static electricity, followthese techniques during servicing, troubleshooting and repair.

1. Assemblies containing semiconductors should be removedfrom their protective containers only under the following con-ditions:

a. When at a designated static free work station.

b. Only after firm contact with an antistatic mat and/orfirmly gripped by a grounded individual.

2. Personnel handling assemblies with semiconductorsshould be neutralized to a static free work station by a ground-ing wrist strap that is connected to the station or to a goodground point at the field site.

3. Do not allow clothing to make contact with semiconduc-tors. Most clothing generates static electricity.

4. Avoid touching edge connectors and components.

INSTALLATION

3 - 2 I-E67-43-1A

5. Avoid partial connection of semiconductors. Semiconduc-tors can be damaged by floating leads, especially the powersupply connector. If an assembly must be inserted in a live sys-tem, it should be done quickly. Do not cut leads or lift circuitpaths when troubleshooting.

6. Ground the test equipment.

7. Avoid static charges during maintenance. Make sure thecircuit board is thoroughly clean around its leads but do notrub or clean with an insulating cloth.

NOTE: An antistatic field service kit, Bailey part number 1948385_1,is available for personnel working on devices containing static sensi-tive components. The kit contains a static dissipative work surface(mat), a ground cord assembly, wrist bands and alligator clip.

UNPACKING AND INSPECTION

Examine the equipment upon receipt for possible damage intransit. File a damage claim with the transportation companyresponsible, if necessary. Notify the nearest TBI-Bailey salesoffice.

Carefully inspect the packing material before discarding it tomake certain that all mounting equipment and any specialinstructions or paperwork have been removed. Careful han-dling and installation will insure satisfactory performance ofthe unit.

Use the original packing material and container for storage.Select a storage environment free of corrosive vapors,extremes of temperature and humidity. Storage temperaturesmust not exceed the range of -20 degrees to +65 degrees Cen-tigrade (-4 degrees to +149 degrees Fahrenheit).

LOCATION CONSIDERATIONS

The design of the Type TB701 pH analyzer allows for panelmounting, pipe mounting or wall mounting. Select an installa-tion site that is free from vibration and that conforms to thetemperature and humidity constraints listed in the specifica-tions table in Section 1. Careful placement of the analyzer willinsure proper operation as well as overall safety.

NOTE: Temperature is an important consideration. Allow for ade-quate air flow, especially if the analyzer is to be installed in anenclosed area.

INSTALLATION

I-E67-43-1A 3 - 3

Use the analyzer with 120, 220 or 240 VAC, 50/60 hertz, lineservice. This setting is jumper selectable (refer to SELECTINGOPTIONS). Make the proper power source available at theinstallation site. It should contain a power line on/off switch.

Hazardous Locations

Refer to the specification table in Section 1 for a listing ofagency approvals that are in effect or pending. Refer to theInstalling a 4 to 20 mA Transmitter in a Hazardous Loca-tion application guide for additional information when usingequipment in a hazardous area.

Radio Frequency Interference

Most electronic equipment is influenced by radio frequencyinterference (RFI). Caution should be exercised with regard tothe use of portable communications equipment in the area.Post appropriate signs in the plant.

SAFETY CONSIDERATIONS

In addition to those precautions taken when using the analyzerin hazardous locations, there are other safety issues to con-sider.

WARNING

Use this equipment only in those classes of hazardous loca-tions listed on the nameplate. Uses in other hazardous loca-tions can lead to unsafe conditions that can injure personneland damage equipment.

J11 on the main board and J1 on the preamp board or pHboard set the analyzer to accept analog inputs.

Failure Detection Option

Refer to Figure 3-1 and Table 3-4. The analyzer continually runsa set of self-diagnostics to insure proper operation of the con-troller. Use J10 (main board) to select the response of the ana-lyzer if it detects on-board failure. Jumper J10, position two tothree, holds the analyzer in a fail-safe condition as the digitaloutputs de-energize and the analog outputs go to zero volts orzero milliamps. Jumper J10, position one to two, allows theanalyzer to automatically reset itself in an attempt to resolve thefailure and come up running, if the diagnostics pass.

MOUNTING

The analyzer can be panel mounted, wall mounted or pipemounted. This section also includes mounting instructions forthe preamp (if ordered).

NOTES:1. Weatherproof connectors should be installed in the wiring entryopenings. An example of weatherproof connectors would be HubbelSHC/NHC series, Daniel Woodhead F2 series, etc.

2. When choosing a mounting location for the analyzer, rememberthat maximum distance between the sensor and the analyzer is 30.5meters (100 feet) without a preamplifier. With a preamplifier, themaximum distance is 305 meters (1,000 feet).

WIRING CONNECTIONS AND CABLING

Under ideal conditions, the use of conduit and shielded wiremay not be required. However, to avoid noise problems, it is rec-ommended that power, signal and output wiring be enclosed inconduit and separated. Just prior to entering the housing, rigidconduit should be terminated and a short length of flexible con-duit should be installed to reduce any stress to the housing.

NOTE: To maintain a NEMA 4X rating, use approved conduit con-nections.

Shimming Long Conduit Fittings

When installing conduit fittings, check the clearance betweenthe conduit fitting when installed in the ½-inch conduit portand the BNC connector used for pH sensor cable. If a clearanceproblem does exist:

1. Remove the top portion of the conduit fitting.

2. Add washers to the fitting before reinserting the threadedportion of the fitting through the housing again.

These washers will shim the conduit fitting up and away fromthe BNC connector.

Figure 3-8. Preamp Assembly Mounting

CAUTIONTo prevent possible signal degradation, a separate metal con-duit run is recommended for the sensor cable.

ATTENTIONAfin d'éviter la défaillance des signaux, il est recommandéd'acheminer le câble de la sonde dans un conduit métalliquedistinct.

Wire Size

The analyzer has the capacity for eleven 14-gauge wires. Ifadditional 14-gauge wire is required, some of the other wiresmust be reduced in size.

For those applications requiring CSA compliance and morethan four two-wire inputs plus outputs are used, then some orall of the wires must be reduced in size. The internal volume ofthe wiring compartment is about 17 cubic inches. The volumerequired for each conductor is:

26-22 AWG 0.50 cubic inches20 AWG 0.75 cubic inches18 AWG 1.00 cubic inches16 AWG 1.25 cubic inches14 AWG 1.50 cubic inches

The total number of conductors multiplied by the volumerequirement of each conductor should not exceed 17 cubicinches. This includes the power conductors.

A wiring label is provided on the rear cover of the housing. Thislabel contains a nonpermanent adhesive to allow carefulremoval and replacement wherever it is convenient.

Inserting the Wire into the Connector

1. Spring clamp type, lugless connectors are provided at therear of the housing for making wiring connections. Maximumwire gauge for the connector is 14 AWG. Minimum wire gaugeis 26 AWG.

2. Insert a small flat blade screwdriver into the connector andpush. This opens the jaws of the connector and the strippedwire can be inserted (Figure 3-9).

NOTE: Strip the wire insulation back approximately 7 millimeters(0.25 inches) to assure that there is enough bare wire for the jaws ofthe connector to contact, but not too much as to leave exposed wirebeyond the connector.

3. Once the wire is in place, remove the tool.

INSTALLATION

I-E67-43-1A 3 - 17

AC Power Wiring

The analyzer is shipped from the factory set for 120 or 240 VAC(nominal), depending on the nomenclature ordered for the ana-lyzer.

Use a standard three-prong grounded flexible CSA certified linecord for power supply connection or the AC supply must behard wired.

1. If hard wiring the AC power supply, it is recommended thatall power wiring be stranded, copper conductor, 14 AWG, andbear a suitable voltage rating for the highest voltage connectedto the termination board (either signal or power) and a 75°C(167°F) minimum rating. Wiring must be in accordance withthe National Electrical Code.

NOTES:1. TBI-Bailey Controls Company recommends installing a powerline switch to the analyzer for safety purposes and for providingpower up and power down convenience while servicing the unit.

2. Do not power the system from a transformer which also powerslarge motor loads (over 5 horsepower) or any other type of equip-ment which will generate line voltage surges and sags.

INSTALLATION

3 - 20 I-E67-43-1A

DIRECT SENSOR CONNECTION

1. The pH sensor has a coaxial cable with a male BNC connec-tor.

NOTE: When using the direct sensor connection method, do not usethe ½-inch knockout for conduit connection that is above the BNCconnector. The conduit connection hardware will interfere with con-necting and disconnecting the sensor BNC.

2. Connect the sensor coaxial cable to the female BNC con-nector on the back of the analyzer (Figure 3-10).

3. Connect jumper wires to the temperature compensationleads (Figure 3-12). Use 26-20 AWG wires.

NOTE: Soldering the jumper wires to the temperature compensationleads is recommended. Errors may occur in temperature measure-ment and compensation may intermittently occur if poor wire con-nections exist.

4. Connect each temperature compensator wire to the tem-perature compensation terminals TB4-1 through TB4-4 asshown in Figure 3-10.

NOTE: If no temperature compensator is used, be sure no wires areconnected to TB4-1 through TB4-4.

PREAMPLIFIER SENSOR CONNECTION

NOTE: Using the preamplifier sensor connection method requires asix-conductor shielded cable, 16 AWG maximum.

The pH sensor has a coaxial cable with a male BNC connector.

Preamp connections 1. Connect the sensor coaxial cable to the female BNC con-nector on the preamp assembly.

2. Connect the 2 sensor temperature compensator wires to ter-minals 7 and 8 (AUTO TC INPUT) on the preamp (Figure 3-11).

Analyzer connections 1. Connect the 4 wires to analyzer terminal block positionsTB3-1 through TB3-4 according to the color coding shown inFigure 3-11.

2. See Figure 3-12 and connect jumper wires to the blue andyellow wires that connect to TB4-1 and TB4-4 (Figure 3-11).Use 26-20 AWG wires.

NOTE: Soldering the jumper wires is recommended. Errors mayoccur in temperature measurement and compensation may intermit-tently occur if poor wire connections exist.

3. Connect the other end of the shielded cable to the backof the analyzer. Use terminal blocks TB3-1 through TB3-4and TB4-1 through TB4-4. Use the color coding shown inFigure 3-11.

4. Connect the shield of the 6-wire cable to the ground termi-nal TB1-12 ( ) on the back cover of the analyzer.

Voltage and Current Analog Output Wiring

Wiring used for analog outputs must be carefully chosen, withconsideration for environmental and electrical conditions.

Shielded (overall or individually) twisted-pair wires for low levelsignal conduction are recommended to reduce the effects ofelectromagnetic and electrostatic noise coupling. An aluminumMylar type with a drain wire has a very good electrostatic cou-ple shield efficiency. All shields must be electrically insulatedfrom other shields. Shields are to be grounded at the sameearth ground potential as the AC power wiring of the analyzer.

NOTE: Do not connect the field end of the shield to a ground.

Conduit is recommended for the field portion of the run. Wher-ever practical, it is recommended that trays containing analogsignals be devoted exclusively to that use. Conduit containinganalog signals should cross power lines, etc., at right anglesand remain perpendicular for at least ten times the diameter ofthe crossed element on either side of the crossing joints.

Maximum wire gauge for the connectors on the rear of thehousing is 14 AWG; minimum is 26 AWG. Wiring must bear asuitable voltage rating for the highest voltage present (eithersignal or power) with a 75 degrees Centigrade (167 degreesFahrenheit) minimum rating. Wiring must be in accordancewith the National Electrical Code (NEC).

INSTALLATION

3 - 22 I-E67-43-1A

Connect the analog outputs using the external wiring label(Figures 3-10 and 3-11) on the outside of the rear cover as aguideline for terminal block assignments.

Digital Input/Output Wiring

Digital input wires should be twisted pair, stranded wires insu-lated with low leakage insulation materials. Individuallyshielded pairs provide greater protection against noise andcrosstalk then nonindividually shielded pairs. Shields are to begrounded at the same earth ground potential as the AC powerwiring.

NOTE: Do connect the field end of the shield to a ground.

Maximum wire gauge for the connectors on the rear of thehousing is 14 AWG; minimum wire size is 26 AWG. Wiringmust bear a suitable voltage rating for the highest voltage con-nected to the termination board (either signal or power) and a75 degrees Centigrade (167 degrees Fahrenheit) minimum rat-ing. Wiring must be in accordance with the National ElectricalCode.

Connect the digital inputs and outputs using the external wir-ing label (Figures 3-10 and 3-11) on the outside of the rearcover as a guideline for terminal block assignments.

OPTION BOARDS INSTALLATION

If ordered by nomenclature, the option boards are installed inthe analyzer at the factory. If the option boards are ordered byspare parts kit number, refer to Section 11 for procedures toinstall the option board.

DISPLAY CONTRAST ADJUSTMENT

The only adjustment required before placing the analyzer intoinitial operation is the display contrast adjustment. The dis-play contrast has been preset at the factory. Due to variancesin lighting at the installation site, it might be necessary toadjust the contrast of the display. Once the unit has beeninstalled, wired and powered up, check the display and adjustif necessary.

NOTE: The circuit boards contain semiconductors and are subjectto damage by static electricity. Refer to SPECIAL HANDLING .

1. Power up the analyzer and check the display contrast.

2. Remove power from the analyzer.

SECTION 4 - CONFIGURATION

INTRODUCTION

This section provides the required actions to establish anddefine the configuration of the Type TB701 pH analyzer. Themain board allows programming and storage of the controlconfiguration. The configuration is saved in NVRAM. This sec-tion is divided into three configuration modes available withthe analyzer:

• Basic analyzer.• PID controller.• Bidirectional controller.

The subsection for basic analyzer provides a complete configu-ration procedure and functionality table (Table 4-1). The PIDand bidirectional controller subsections contain only thoseprocedures that differ from the basic analyzer. The functional-ity for the PID and bidirectional controllers is listed in Tables4-2 and 4-3. These tables provide a summary of all the configu-ration choices available that appear on the screens.

All analyzer configurations contain basic analyzer functional-ity. Basic analyzer configurations include choosing one of theconfiguration modes available, choosing a temperature com-pensation mode, temperature display units and input damp-ing, as well as alarm reporting functions.

NOTES:1. The screen displays illustrated in this section contain circlednumbers. Those numbers reference the step number of the proce-dure and do not appear on the actual screens.

2. Whenever there is more than one choice available on a screendisplay, the choices are bracketed [ ] on the screen illustration andthe choices explained next to the screen. The choices are summa-rized in the tables (Tables 4-1, 4-2 and 4-3) at the end of each con-figuration mode section.

3. The graphics of the screens presented are close representa-tions, but data may vary in size and position.

CONFIGURATION DATA REQUIRED

Before entering a configuration, use the information inSection 2 and define the following:

1. Configuration mode.

2. Remove the worksheets in Appendix D and enter the infor-mation as the configuration is designed. The worksheets helpduring the configuration entry procedure.

3. Analyzer parameters.

4. Controller parameters (if PID or bidirectional).

5. Analog outputs.

6. Digital outputs.

7. Alarms.

BASIC ANALYZER

The basic analyzer configuration provides a means to monitorand control the pH of a process fluid. Control of the final ele-ment is achieved by using the digital (relay) outputs in either asimple ON/OFF or ON/OFF cycle timer mode (refer toSection 2). The analog outputs in this configuration are dedi-cated for recorder datalogger, etc., outputs. The process dis-play shows the pH input, process temperature, user-specifiedset points and the analog output.

Analyzer Parameters

The procedures under ANALYZER in this next screen involveselecting the sensor type, choosing a temperature compensa-tion mode, and selecting the temperature display units anddamping.

1. Press or to highlight ANALYZER. Press .

2. The sensor choice and temperature compensation choicescreen appears.

SENSOR TYPE

Two sensor choices are available: Standard pH or antimony.

1. Select STANDARD pH for any pH sensor having a glasselectrode as the measuring element and a Ag/AgCl (silver/sil-ver chloride) reference with KCl (potassium chloride) electro-lyte. Efficiency calculations assume calibration to 25°C (77°F)with a theoretical slope of 59.15 mV per pH unit. All tempera-ture compensation choices are compatible with this choice.Thermo-isopotential is a 7.00 pH. Reference offset calibrationassumes a saturated KCl reference potential of -30 mV as nor-mal (i.e. displayed as a 0 mV offset).

2. Select ANTIMONY for a pH sensor having an antimonymetal measuring electrode that will be used in highly erosive

applications. These sensors require abrasion across the elec-trode face to work efficiently. A freshly abraded antimony sen-sor will produce a nominal slope of 51 mV per pH unit.Isopotential point is 1.0 pH. Efficiency is factored at the 59 mVvalue. Therefore, a normal efficiency reading will be 86% orless. A lack of fresh antimony surface will lower this efficiency.A Ag/AgCl (silver/silver chloride) reference with KCl (potas-sium chloride) electrolyte is used with antimony sensors. As inthe standard pH sensor, this reference produces -30 mV whichis used as the null point for reference offset calculation. Tem-perature compensation choice must be MANUAL to be compat-ible with the antimony sensor choice and is only for thepurpose of temperature display.

3. Press or to select sensor choice, STANDARD pH orANTIMONY. Press to confirm the choice. The highlight willmove to TEMP. COMP.

MANUAL compensates the pH value for the effects of tempera-ture on the sensor (Nernstian effect) at a specific temperature.No automatic temperature compensator is required.

NOTE: If antimony was selected as the sensor type, MANUAL isautomatically selected for the temperature compensation.

STANDARD AUTO corrects the pH reading for the effects oftemperature on the pH sensor for any temperature within therange of measurement. Correction is to 25°C. This choicerequires an input from a 3.0-kilohm Balco RTD temperaturesensing device.

AUTO/SOLUTION compensates for the effect of temperature onthe pH sensor in the same way as the standard auto method.Additionally, it allows a user-entered coefficient to match theeffect of temperature on solution pH according to a mathemati-cal formula. This choice requires an input from a temperaturesensing device.

2. If MANUAL is selected, the process temp screen will appear.Press or to set the correct temperature. The range is-20°C to +150°C (or equivalent °F).

3. If AUTO/SOLUTION is selected, the solution coefficientscreen will appear. Press or to set the correct value. Therange is -1.000 to +1.000.

Example: Pure water +0.18 pH per 10°CPure water with 1 ppm ammonia +0.31 pH per 10°C

SECTION 6 - CALIBRATION

INTRODUCTION

This section describes the steps used to calibrate the input andoutput of the Type TB701 pH analyzer. Information on the cali-bration screen includes PROCESS CAL PH, BENCH CAL PH,PROCESS CAL TEMP, BENCH CAL TEMP and ANALOG OUT.

Before calibration can begin, the proper configuration must beloaded and saved to memory as described in Section 4.

NOTES:1. To escape any configuration operation without saving, press amulti-function soft key and back through the previous screen, go tothe process display or press the ESC (escape) soft key.

2. The screen displays illustrated in this section contain circlednumbers. These numbers reference the step number for the proce-dure listed. The numbers do not appear on the actual screen.

General Process Calibration Information

PROCESS PH CAL is the recommended one-point calibrationprocedure to periodically calibrate field sensors after they havebeen installed in the process. Calibration frequency is depen-dent on the application.

Information is also provided on sensor calibration. Sensorsshould be cleaned before a process calibration. Refer to SEN-SOR MAINTENANCE in Section 10 for detailed sensor cleaninginstructions.

General Bench Calibration Information

Bench calibration is referred to as a two-point calibrationprocedure. There are two types of bench calibration:

• Calibration using a millivolt source (pH simulator).• Calibration with new sensors.

Which type of bench calibration procedure to use will dependon the application and where the sensor is in its life cycle (i.e.,new or used).

A bench calibration with a millivolt source or pH simulator isrecommended for initial setup and periodic calibration of theanalyzer. Always follow this procedure with a process cal-ibration with a sensor or a field checkout using bufferstandards.

CALIBRATION

6 - 2 I-E67-43-1A

A bench calibration using buffer standards is recommendedfor periodic checkout of some field sensors. Always followthis procedure with a grab sample process calibration.

A field checkout using buffer standards is recommended fordetermining response and slope of field sensors. This is not acalibration procedure.

NOTE: Before performing standard solution calibrations with fieldsensors, refer to FIELD CHECKOUT USING BUFFER STAN-DARDS and do an initial compatibility check between the sensor,the process and the standard.

PROCESS CAL pH

The process calibration is a one-point calibration done in thefield. For the highest accuracy, a grab sample method is thebest technique. A process calibration is the recommended cali-bration procedure to periodically calibrate field sensors afterthey have been installed into the process.

Grab Sample Method

A grab sample method consists of:

1. Withdrawing a sample from the process piping or tank nearwhere the sensor is located.

2. Measuring the sample with a lab or portable analyzer.

3. Entering the calibration information into the analyzer.

WARNING

Place the equipment in the MANUAL mode before performingthis procedure. During this procedure, the equipment executesthe user-entered configuration. The MANUAL mode locks outother equipment and prevents accidental engagement of thatequipment that can upset the process. Some process upsetscan injure personnel and damage equipment.

AVERTISSEMENT

Mettez l’équipement en mode MANUEL avant d’effectuer cetteprocédure. Au cours de cette procédure, l’équipement exécutela configuration introduite par l’utilisateur. Le mode MANUELverrouille le reste de l’équipement et en empêche l’activationaccidentelle susceptible de perturber le processus. Certainesperturbations du processus pourraient provoquer desblessures et des dommages matériels.

CALIBRATION

I-E67-43-1A 6 - 3

To implement this method:

1. Withdraw a representative sample of liquid being measuredby the sensor from the process stream as the grab sample.

2. Measure the grab pH sample immediately after withdraw-ing it from the process stream. Do not let the grab sample cool.

3. Record or memorize the indication on the analyzer at thesame time the grab sample is taken.

4. Use only the difference between the grab sample mea-surement and the analyzer reading to adjust the pH value dis-played on the calibration screen.

Example: The analyzer reads 10 pH when the grab sample is taken. The grab sample ismeasured to be 11 pH. Upon return to complete calibration, the analyzer nowreads 10.5 pH. Adjust the analyzer up 1 pH unit to read 11.5 pH.

10.5 pH + (11 ∠ 10) = 11.5 pH

Process Calibration Procedure

To perform the process calibration procedure:

1. From the MAIN MENU, press or to highlight CALI-BRATE. Press .

NOTE: A calibration password screen appears if a password hasbeen assigned. When the correct password is entered, or if nosecurity level is placed on calibration, the calibration menu appears.

2. When the calibration menu appears, PROCESS CAL PHshould be highlighted. If it is not, press or until it is.Press .

CAUTION

When measuring the pH of a grab or lab sample, make surethat the temperature of the sample is compensated. In somecases, the pH of the solution may change value as the samplecools. Grab samples should not be left open to the atmo-sphere. Samples may change or deteriorate as time passes. Itis important to measure grab samples as soon as they aretaken.

ATTENTION

Lorsqu'on mesure le pH d'un échantillon ponctuel ou d'unéchantillon de laboratoire, il faut s'assurer de compenser latempérature de l'énchantillon. Dans certains cas, la valeur dupH de la solution peut changer à mesure que l'énchantillonrefroidit. Il ne faut pas laisser les échantillons ponctuels a l'airlibre. Ceux-ci peuvent être modifiés ou altérés si on ne lestraite pas rapidement. Il est important de mesurer les échantil-lons ponctuels dés qu'ils sont prélevés.

Bench Calibration Using Millivolt Source or pH Simulator

A bench calibration with a millivolt source or pH simulator isrecommended for initial setup and periodic calibration of theanalyzer. Always follow this procedure with a process cal-ibration via a grab sample.

NOTE: All units have this procedure performed at the factory. It isnot necessary to do this on a new analyzer.

This procedure is only required for initial setup if the analyzerwas not received from TBI-Bailey Controls Company or anauthorized representative. It is also advised to perform thisprocedure if it is suspected that the analyzer is defective.

Equipment required:

• Millivolt source with a full scale range -500 to +500 milli-volts.

or

• pH simulator.

1. Connect the millivolt source to the BNC connector on theback of the analyzer. The inner conductor of the BNC connectorcorresponds to the positive input and the outer shell corre-sponds to the negative input.

Bench Calibration Using Buffer Standards and a New Sensor

A bench calibration using buffer standards is recommendedfor new sensors and for periodic checkout of some field sen-sors. Always follow this procedure with a grab samplePROCESS CAL PH procedure.

While this procedure is adequate for a laboratory bench cali-bration, a process calibration must be performed in the fieldafter the bench calibration. This is due to the differencesbetween the lab conditions and the temperature, pressure andflow of the process.

For new sensors:

1. Unwrap the sensor.

NOTES:1. If the cap that was on the sensor tip is dry, put the sensor in abeaker of buffer or salted tap water for 2 hours before attempting thecalibration procedure.

2. Steps 1 through 8 require that no adjustments be made to theanalyzer. They are designed to wake up the sensor.

FIELD CHECKOUT USING BUFFER STANDARDS

NOTE: This is not a calibration procedure. In some cases, a fieldcheckout using buffer standards is recommended for checking outfield sensors. This procedure is mainly for checking sensor responserather than analyzer readings.

Most processes have different chemical structures than bufferstandards. As a result, buffer calibrations with sensors thathave spent all of their lives in processes usually result in incor-rect process readings. On the other hand, lab sensors spendmost of their time in standards and adapt well to standard cali-brations; however, they often read process pH incorrectly. This

is why TBI-Bailey Controls Company recommends grab samplecalibrations as opposed to standard calibrations. There aresome situations where a grab sample calibration is impossibleor buffers are required for calibration. To determine if the sen-sor, process and buffer solution are compatible enough to per-form a two-point buffer calibration, or to see if the sensor isreacting properly, perform the following procedure.

NOTE: Sensor response is more important than analyzer readings.Read this section with that in mind.

Do not use the calibration menu. Leave the analyzer in the nor-mal operating mode.

1. Remove the sensor from the process. If the process is hotteror colder than the weather, put the sensor in a bucket of wateruntil it reaches the ambient temperature.

2. Clean the sensor. Refer to Section 10 for instructions.Many oils and organics are translucent (cannot be seen). Slug-gish response indicates this type of fouling. Many scales can-not be seen if the glass is wet. Dry the glass off and hold it upto the light. If it is not totally clear, it is either abraded or has ascale. If after cleaning it still is not clear, then it is most likelyabraded. Response time will dictate whether it should betrusted or replaced.

3. Liberally rinse the sensor with tap water.

4. Place the sensor in a 7 pH buffer. Stir the buffer with thesensor. Let the sensor sit in the buffer 1 minute minimum.

5. Take the sensor out of the 7 pH buffer. Thoroughly cleanthe sensor with tap water.

6. Place the sensor in a 4 pH buffer. Stir the buffer with thesensor. Let the sensor sit in the buffer 1 minute minimum.

WARNING

Place the equipment in the MANUAL mode before performingthis procedure. During this procedure, the equipment executesthe user-entered configuration. The MANUAL mode locks outother equipment and prevents accidental engagement of thatequipment that can upset the process. Some process upsetscan injure personnel and damage equipment.

I-E67-43-1A 6 - 13

7. Take the sensor out of the 4 pH buffer. Liberally rinse thesensor with tap water. Make no adjustments to the analyzer.

8. The sensor is now ready to be tested.

9. Place the sensor in the 7 pH buffer. Stir with the sensor for5 seconds, then let the sensor sit in the buffer. Do not touchthe cable. Note how quickly it reacts. Also note the pH readingwhen it has stabilized.

10. Quickly rinse the sensor with tap water.

11. Place the sensor in a 4 pH buffer.

12. Stir for 5 seconds, then let the sensor sit in the buffer.

13. If at this time the pH reading is more than 2.5 pH below thereading in Step 9 and is stable or continuing to move towards 4pH, the sensor is good and can either be put back in the pro-cess or a bench calibration can be performed. If it is not, wait30 seconds and check the reading again. If the reading is then2.5 pH below the reading in Step 9, the efficiency can beadjusted to make up the difference (88% is recommended) orperforming a buffer bench calibration later can make up mostof the difference. This could create problems later. Before doingthis, go to Step 14.

14. Stir the buffer with the sensor again. Wait 2 minutes. If thereading is stable and between 2.2 and 2.7 pH units below thereading in Step 9, better cleaning is required. Refer toSection 10. If the sensor was already cleaned, try a differentcleaning procedure.

15. If after 2-½ minutes the sensor reads less than 2.2 pHunits from Step 9, 1 of 4 things is taking place:

a. The cleaning solution used on the sensor is not effec-tive. Try a different method.

b. The sensor is old and tired. Replace sensor.

c. The analyzer or cabling has a problem. Refer to Sec-tions 8 and 9.

d. The sensor does not like buffer solutions. If it reactsfine in the process, trust it. Do a process calibration andput it back in service.

NOTE: If the buffers turn cloudy when the sensor is put in it, or if aprecipitate forms in the buffer after the process sensor is put in it,there is nothing wrong with the sensor. There is just a huge incom-patibility between the process and the buffer. A buffer calibration isimpossible. Do a grab sample calibration.

SECTION 8 - DIAGNOSTICS

INTRODUCTION

This section provides information on analyzer power up diag-nostics and various diagnostic tools available to aid in deter-mining analyzer and sensor problems.

POWER UP DIAGNOSTICS

The Type TB701 pH analyzer performs a number of diagnosticchecks that flag faults in NVRAM, configuration and ROMintegrity. If an error is detected:

• An error message appears on the display (Table 8-1).• Execution of the user-entered configuration stops.• All analog outputs go to zero volts (zero milliamps).• All digital outputs are de-energized.• NVRAM is inhibited (cannot be erased or written to).

GENERAL DIAGNOSTICS

General diagnostics include alarms for calibration errors, PVhigh and low, and temperature high and low. Additionally,individual digital outputs may be programmed to indicate mea-surement loop errors particular to the type of application forwhich the analyzer and sensor are used (Table 8-2). All alarmslisted except the CAL ERROR alarm will show up as an alarmon the display and will be listed in the alarm summary. TheCAL ERROR alarm will appear on the display during the cali-bration procedure.

Table 8-1. Power Up Display Error Messages

Display Error Description Corrective Action

RAM OVERLOAD The analyzer fails the NVRAMchecksum test.

Cycle the analyzer power off and on. If the conditiondoes not clear, initialize NVRAM. Refer to NVRAMINITIALIZATION (ERASING NVRAM) in Section 9.

CHECKSUM FAIL The analyzer fails the ROMchecksum test.

Replace the ROM. Contact TBI-Bailey.

CNFG ERROR The analyzer fails theconfiguration checksum test.

Initialize NVRAM. Refer to NVRAM INITIALIZATION(ERASING NVRAM) in Section 9.

DIAGNOSTICS

8 - 2 I-E67-43-1A

SENSOR DIAGNOSTICS

The analyzer also has several diagnostic tools to aid in serviceof the sensor:

• Sensor efficiency.• Sensor offset.• Sensor temperature low.• Sensor temperature high.

These values are calculated during the calibration procedure.Efficiency and offset values are updated and displayed duringbench or process pH calibration. These values can be viewed byaccessing the PROCESS CAL PH menu and escaping withoutentering a new pH calibration value. Sensor temperature statusis displayed as an alarm if not within the defined values.

Sensor Efficiency

The calculated sensor efficiency is determined by the actualslope of the sensor. Sensor efficiency is calculated by theactual slope divided by the slope of a theoretically perfect sen-sor. An acceptable range of sensor efficiency is between 70 and100 percent. If the calibration calculations show the efficiencybelow the acceptable range, actual solution temperature, aswell as solution pH at that temperature, must be verified.Incorrect entry of these parameters is the most common causeof low efficiency calculations.

Other causes are fouled or exhausted pH sensors. Clean thesensor thoroughly (refer to Section 10) and repeat the benchcalibration procedure (refer to Section 6). If the second calibra-tion again shows efficiency below 70 percent and the sensorreacts slow, sensor replacement may be advisable.

DIAGNOSTICS

I-E67-43-1A 8 - 3

Low efficiency display with a sensor that reacts quickly tobuffer changes indicates the sensor is in good condition, butthat incompatibilities between process and buffer chemistriespreclude accurate buffer calibration. Process calibration with amanually entered 95 to 98 percent efficiency is strongly recom-mended.

Sensor efficiencies above 100 percent are theoretically andpractically impossible. Only improper calibration causes a sen-sor efficiency above 100 percent. Typical calibration errorsinclude entering too low a temperature or an incorrect pHvalue. As the pH of the buffer solution changes with tempera-ture, the buffer temperature must be entered accurately. Thechange in buffer pH must also be considered when entering thepH calibration value.

Repeated attempts that result in sensor efficiencies above 100percent indicate that final calibration must be done using theprocess calibration procedure.

NOTE: Antimony pH sensors may be quite serviceable with efficien-cies as low as 50 percent. A typical antimony sensor will have anefficiency of 84 to 90 percent when new and freshly abraded.

Calculated Sensor Offset

The calculated sensor offset displays in millivolts. Millivoltsource calibration results in a +30 millivolt display, becausethis feature assumes a normal offset of -30 millivolts with newTBI-Bailey pH sensors (new TBI-Bailey sensors will typicallydisplay a calculated offset of zero to ±20 millivolts).

An acceptable range of offset is ±150 millivolts, dependingupon the application and age of the sensor. Generally, the sen-sor offset (reference potential) gradually increases as a sensorages. If the increase is gradual, this is no cause for concern.Stability of the reference offset is the greater concern. Theeffect of sensor reference offset is eliminated during the benchor process calibration of the analyzer. Sensor replacementshould be considered if the offset ever exceeds the acceptablerange.

Sensor Temperature High/Low

An automatic temperature compensator is required before thisdiagnostic feature can be functional. Full diagnostic capabilityis affected only if the automatic temperature compensator isintegral to the pH sensor. Use of Type TB590 separate temper-ature compensator results in diagnostic capability that doesnot include potential sensor deficiencies.

DIAGNOSTICS

8 - 4 I-E67-43-1A

Indication of sensor temperatures below -20 degrees Centi-grade (-4 degrees Fahrenheit) or above 150 degrees Centi-grade (302 degrees Fahrenheit) will be indicated as an alarmon the faceplate display and can be accessed through theALARM SUM soft key. No TBI-Bailey pH sensor is rated for usebelow -5 degrees Centigrade (23 degrees Fahrenheit). Uppertemperature limits are 50 degrees Centigrade (122 degreesFahrenheit), 100 degrees Centigrade (212 degrees Fahren-heit), or 140 degrees Centigrade (284 degrees Fahrenheit)depending on the type of sensor used. Use of the sensor aboveor below the high/low diagnostic limits generally causes sen-sor damage, resulting in inaccurate pH measurements.

Additionally, other measurement deficiencies may be indi-cated. These deficiencies, in order of occurrence probability,are as follows:

1. Automatic temperature compensator not connected to sol-dered jumper wire connections.

2. Process temperature above or below limits of the pH sensor.

3. Sensor cable connectors wetted (incorrect pH readingsresult).

4. Sensor cable damaged (incorrect pH readings result).

5. Extension cable (if used) not connected (incorrect pH read-ings result).

6. pH sensor internally shorted or cracked (incorrect pH read-ings result).

7. Temperature compensator open or shorted (incorrect pHreadings result, but the sensor can still be used in manualtemperature compensation mode).

8. pH sensor physically broken (incorrect readings result).

NOTE: Shorted, cracked, or broken pH sensor assemblies will notalways cause the temperature compensator high/low temperaturediagnostics to activate.

If trouble with the sensor is evident, refer to Tables 9-1 and9-2.

SECTION 9 - TROUBLESHOOTING

INTRODUCTION

This section provides troubleshooting information for the TypeTB701 pH analyzer and sensor. In addition to describing possi-ble error conditions that could occur with the analyzer and thecorrective actions to take to remedy the situation, it also con-tains procedures for checking possible sensor problems andground loops. If the analyzer software locks up, there are proce-dures in this section for erasing the NVRAM, and also a rebootprocedure that will return the analyzer to factory defaults.

Refer also to Section 8 for a list of analyzer alarm messages. SeeFigure 9-1 for a troubleshooting flowchart.

ANALYZER TROUBLESHOOTING

Troubleshooting the Analyzer Without the Sensor

Sensor simulation by millivolt substitution is an easy way tocheck the operation of the analyzer without the sensor. Use itto check digital output activation and analog output accuracy.Use it also to see if the analyzer reacts properly to simulatedprocess conditions.

Before performing sensor simulation, initialize the analyzer sothat it returns to factory default calibration.

Use the following equipment to perform these procedures:

• Millivolt source with a high impedance (1,000 megohm)switch or button.

1. Disconnect the sensor from the analyzer.

2. Disconnect the temperature compensator.

3. There are 2 ways to perform sensor simulation once thesensor leads and temperature compensator leads are discon-nected.

a. Place a 3-kilohm resistor across the temperature com-pensator input with a constant 25°C (77°F) temperaturedisplay.

or

b. Configure the analyzer for standard manual temperaturecompensation (none) with a constant 25°C temperature.

TROUBLESHOOTING

3. The reading should quickly climb to infinity as indicated byan ohmmeter in its highest range. A reading near 0 indicates adirect ground connection. If this is not the source of theground loop, continue with Step 4.

4. Place the sensor in a glass or plastic beaker of processfluid.

NOTE: Be sure the outside of the beaker is dry.

5. Note the analyzer reading.

6. Ground the solution with a wire connected to a good earthground.

7. If the analyzer reading shifts a ground loop could bepresent. Refer to Section 3 to verify proper wiring and ground-ing or contact TBI-Bailey service.

NVRAM INITIALIZATION (ERASING NVRAM)

NOTE: This procedure is not required for first-time installations. Ifinstalling the analyzer after removing it from service and a new con-figuration is necessary, this procedure will erase the existing config-uration.

The NVRAM (nonvolatile random access memory) stores theanalyzer configuration. This type of memory is used because itcan be written to electrically, but will retain data in the event ofa power failure. Use this procedure if the analyzer softwarelocks up.

Any previously stored configuration in the NVRAM will beerased.

NOTE: Be sure the original configuration is recorded.

1. If power to the analyzer is on, remove the power.

2. While holding the left multi-function soft key below the dis-play, apply power to the analyzer.

APPENDIX A - PROGRAMMING THE PID CONTROLLERAND NONLINEAR INPUT

PID CONTROLLER SETTINGS

This product offers two types of PID controllers. A single loop(PID) controller can be used for either acid or base addition,but not both at the same time. A dual output (bidirectional)controller is used for controlling both an acid and a base addi-tion.

Programming both types of controllers is similar. The main dif-ference is that in the PID controller configuration, only one setpoint, proportional band and reset value are entered. In thebidirectional controller configuration, two set points, propor-tional band and reset values are entered. A description of theconfigurable specifications for each controller follows.

PROPORTIONAL BAND (BOTH)

The proportional band is a percentage of the instrument spanwithin which the control output changes in proportion to thedifference between the process pH and the set point. For thisanalyzer, the instrument span is 14 pH units. As the propor-tional band is increased, the less the output changes for agiven process pH change. Refer to Table A-1 for examples ofproportional band when using a linear to pH input.

RESET (BOTH)

Reset refers to a change in the control output level over aperiod of time in addition to the effect due to the proportionalband action. Reset is entered as repeats per minute and willadd to the control output some portion of the output value asdetermined from process pH deviation from the set point pH. Areset rate of 0.5 repeats per minute will cause the control out-put to change by half the amount caused by the deviation inpH multiplied by 7.14 percent in one minute. Table A-2 listsexamples.

Protective reset anti-windup programming stops the resetaction when the controller output reaches either +105 percentor -5 percent. If the process pH returns to the set point level,the proportional band portion of the control output disappears,but the reset portion will remain until there is another pH devi-ation change (refer to CONTROLLER ACTION (PID SINGLELOOP ONLY)).

DERIVATIVE (PID SINGLE LOOP ONLY)

Derivative refers to an action that adds output to the controllerbased on how fast the process pH is changing. There is noderivative action even if the process pH is two pH units (ormore) from the set point unless the process pH is changing.Derivative action is entered as x.xx minutes. It immediatelychanges the output as much as the proportional band would ina given number of minutes based on the rate of change of theprocess pH. The higher the derivative value, the greater thechange will be. Derivative action bleeds off the control outputwhen the process pH and the resulting proportional outputchange stabilize.

NOTE: The derivative function is not normally advised for pH con-trol. The default value of 0.0 minutes will disable this function. If avalue other than 0.0 is to be entered, it should be very low, other-wise instability could result. The bidirectional controller does nothave derivative action available. If used, derivative values above 1.0will most likely cause unstable controller action.

CONTROLLER ACTION (PID SINGLE LOOP ONLY)

Controller action can be direct or reverse. Direct action is usedto lower the process pH (addition of acid). Reverse action isused to increase the process pH (addition of base).

The controller action sets the internal math that will determinethe error signal used in calculating the proportional outputand reset output values.

DIRECT Action = Process pH – Set point pH = error

REVERSE Action = Set point pH – Process pH = error

When using a nonlinear input to the PID controller, the con-troller action is locked to reverse. The shape of the curveentered will determine the proper error signal. The bidirec-tional controller has the controller action preset.

SET POINT (PID SINGLE LOOP)

Set point is the desired pH to which the process will be con-trolled. It is entered from the process display screen by press-ing to highlight SET POINT and adjusting the valuedisplayed up or down by pressing or .

SET POINTS (BIDIRECTIONAL CONTROLLER)

Set points are the desired pH levels to which the process will becontrolled. The HI SET POINT display is associated with theacid controller. The LO SET POINT display is associated withthe base controller. For best operation, a difference of a mini-mum of 0.5 pH units is advised between the high and low setpoints. Internal lockouts prevent a pH value higher than thehigh set point from being entered as the low set point (and viceversa).

Enter the HI and LO SET POINTS from the process displayscreen by pressing to highlight the appropriate set pointand adjust the displayed value up or down using or .These values can also be changed in the tune or configuremode by accessing the proper submenu.

NOTE: An internal buffer zone between the acid and base control-ler, plus any difference between the high and low set points, cancause an offset to the proportional part of the control output. Thisoffset will be quickly eliminated by the action of the reset portion ofthe controller. During start-up or check-out, this offset may becomenoticeable if the controller is operated in proportional only mode(reset = 0.00 repeats per minute). This should be accepted as nor-mal as long as the offset is no more than ten percent.

Additionally, if a 100 percent output is exceeded (output satu-rated), the controller may not respond in a proportional man-

ner when it comes out of saturation. This is noticeable only ifthe controller is operated without reset, i.e., proportional onlymode.

PROGRAMMING THE CONTROLLER FOR NONLINEAR INPUTS

Often a standard PID controller will not effect good pH control,especially for waste neutralization applications. This isbecause in pH control the process gain is rarely constant. Typ-ical process gains can vary from very small to very large valuesthrough a relatively narrow range of pH. Compounding thiscontrol problem is the fact that, in most all cases, this changein process gain is also nonlinear.

Process gain for pH can be calculated from a plot of pH to vol-ume of chemical addition, i.e., a titration curve (Figure A-1).

Process gain is nothing more than the slope of a line. As can beseen by Figure A-1, a typical pH titration curve has many dif-ferent slopes, that is, process gains. In fact, the slope of pH toreagent demand is different at any two pH values.

This product allows compensating for the nonlinearities of pHprocess gain by entering a five-segment linear relationship ofpH to reagent demand. Any titration curve can be fitted simplyand easily through the following procedure.

1. Derive a titration curve of the process by one of the follow-ing methods.

Method A Take a representative sample of the process to be controlled tothe lab and titrate it with the chemical to be used as thereagent for process control. It is imperative that the chemical

used in the lab be exactly the same as that used in the process.This reagent can be diluted as long as the dilution factor isknown and saved for future calculations.

Method B Manually add the desired chemical to the process while mea-suring input and output pH, process flow (if any), and chemicaladdition flow (or valve/pump position). Input pH is measuredto make sure that no changes in influent pH take place duringthe test. If influent flow is stable, mark the x axis with thereagent flow or 0% to 100% valve opening. If process flow is notstable, mark the x axis with the ratio of process flow to chemi-cal addition or reagent valve opening. The y axis is always thepH after chemical addition. If influent pH changes, enter dataderived after the change on a separate curve.

2. Plot the titration curve on graph paper as shown inFigure A-2.

y axis Always put the high pH value at the top of the graph on they axis.

x axis Always have zero volume at the left of the x axis. Units of mea-surement can be in any units as long as these units are consis-tent for all curves and calculations.

NOTE: Most processes will not have a constant titration curve. It isbest to run numerous titrations and determine a composite or aver-age curve for entry into the Type TB7 analyzer. In some caseswhere severe upsets can occur, it is desirable to average sections ofthe curve. Read this complete appendix before attempting to aver-age any specific section of the curve.

3. Determine the highest and lowest pH values expected to beencountered in the field or those positions indicated by 0% and

100% valve actuation. These values must consider pH valuescaused by process excursions and reagent over-addition. Markthese points on the curve.

4. Divide the x axis marked by the low and high pH values (or0% to 100% valve actuation) of the graph into 10 equal sec-tions as shown by the dotted lines in Figure A-3. Label thesesegments as 0% to 100%.

5. If these points (refer to Step 3) exist on steep slopes, youmay choose to add 2 pH units to the high and low pH valuesand mark these on the curve (Figure A-3). Extending the curvein this manner (i.e., to a less steep gain) may cause a length-ened recovery time for large upsets, but lessens the chance ofovershoot.

6. Using the highest and lowest pH values marked in Step 4or 5 as the start and end points, convert the remainder of thetitration curve into a maximum of 5 straight line segments. Usecare in determining what segments of the curve to linearize, assteep slopes and deflection points must be well represented(Figure A-4). It is desirable to have the area around the control-ler set point well bracketed by straight lines, with areas outsideof the normal control region less represented.

7. After linearizing the curve, calculate the values of the x andy points for each intersection (Figure A-4). Tabulate the inter-sects as shown in Table A-3. Start with low pH values at thetop of the chart.

NOTE: The linearization must be entered according to the arithmeti-cal progression shown in Table A-3 for each configuration and con-trol type. Errors in entering the linearization will adversely affectcontrol.

8. Enter the intersect points starting with x1, then y1, fol-lowed by x2, y2, etc. Note that the pH values are entered as x1through x6, even though they appear on the y axis of the graph.Also note that x2 must be a greater number than x1, etc.

The method of entering y values changes depending on thetype of configuration and control action desired. Table A-3shows the proper arithmetical progression for each type. Thesemust be followed as shown for proper nonlinear control. Acidbidirectional y values are determined by subtracting thegeneric unit on the plotted curve from 100.

It is not necessary to use the full pH scale (-2 through +16)when entering x values. Conversely, y values should use thefull percent scale (0% to 100%). Internally, the controller willlimit output to the y value shown for pH values x1 and x6. Asan example, the controller will deal with values above 12.8. InTable A-3, add acid PID by assigning a generic unit of 0%, and

9. The titration curve has now been entered into the control-ler. Its action will be on the error signal used as a multiplier tothe following PID algorithm (non-interacting controller):

where:

NOTE: The derivative function is not advised for pH control. Thedefault value of 0.0 minutes will disable this function. Bidirectionalcontroller does not have derivative action available.

It can be seen by this algorithm that the proportional bandmust be entered before complete controller linearization can beaccomplished. Entering these values can be done in two ways:by calculation or by educated guess work. As an example,assume it is known that for the process shown by the previousacid addition titration curve, an incoming pH of 10 requires a30% valve opening to neutralize the process to 7 pH.

There are a number of ways to determine the percent controlleroutput needed to effect a specific change in pH. The easiest isto manipulate the valve (or pump) manually and measure theinput and output pH. In another method, the titration curvecan be used to calculate the amount of chemical required tochange the pH of a known volume of process liquid accordingto the following.

where:

10. Determine the integral (reset) settings. As can be seen fromthe equation in Step 9, the integral function is also multipliedby the error signal (which has now been linearized to the titra-tion curve). This means that the effect of the integration will beless at steep parts of the curve than at the flatter slopes. As aresult, the integral function is also linearized, thus allowingconventional running techniques to be used for reset settings.

Example: The integral rate is directly related to the hold-up time of the process. Assumethat neutralization occurs in a 1,000-gallon tank and that the influent flow rateis 100 gallons per minute. The hold-up time is given as volume/flow ratewhich is 10 minutes in this example. The integral rate should be set to:

Because the controllers are a non-interacting type, reset valueswill typically be higher than values used with interacting (con-ventional) controllers.
