CONDENSED OPERATING INSTRUCTIONS

This manual contains details for all operating aspects of the instrument. The following condensed instructions areprovided to assist you in getting the instrument started up and operating as quickly as possible. These condensedinstructions only pertain to basic conductivity measurement operation. To measure % concentration or TDS,or to use specific features of the instrument, refer to the appropriate sections in this manual for instructions.

A. CONNECTING SENSOR/CONFIGURING TEMPERATURE ELEMENT TYPE

1. After properly mounting the analyzer (PART TWO, Section 2), connect the GLI electrodeless conductivitysensor, matching wire colors to terminals as indicated:

Sensor Wire Colors Analyzers with “B” Prefix Serial No. Analyzers with No Letter Prefix Serial No.

Green Terminal #15 on TB1 Terminal #15 on TB1Yellow Terminal #18 on TB1 Terminal #18 on TB1Red Terminal #19 on TB1 Terminal #19 on TB1

Clear (inner shield wire) Terminal #20 on TB1 Terminal #20 on TB1Blue Terminal #21 on TB1 Terminal #21 on TB1

White Terminal #22 on TB1 Terminal #22 on TB1

NOTE: For best immunity to electromagnetic interference, connect the sensor cable’s outer shield wire(clear with black band -- not its clear-only inner shield wire) to:

• The grounding strip at bottom of case (5 open holes, Figure 2-3) for analyzers w/“B” prefix serial nos.• Terminal 11 on TB1 (Figure 2-4) for analyzers with no letter prefix serial numbers.

2. The analyzer is factory-set for automatic temperature compensation using the Pt 1000 ohm RTD built into all GLIelectrodeless conductivity sensors. When you want fixed MANUAL temperature compensation, you must changethe temperature element type (see PART THREE, Section 4.2, subheading “Select TEMP ELEMENT Type”).

B. CONNECTING LINE POWER

Important: Follow the instructions in PART TWO, Section 3.5 to connect line power to the analyzer.

C. ADJUSTING DISPLAY CONTRAST

Ambient lighting conditions may make it necessary to adjust display contrast to improve visibility. With theMEASURE screen displayed, press and hold the ENTER key and simultaneously press the ×× or ØØ key untilattaining the desired contrast.

D. CALIBRATING THE ANALYZER

The analyzer must be calibrated so that measured values will correspond to actual process values. Preferably,use the “COND CAL” calibration method to enter the known value of a properly prepared conductivity referencesolution. (When using a sample of the process to calibrate, use the “SAMPLE CAL” method to enter its valuedetermined by laboratory analysis or a comparison reading.)

Calibration Tip! Each electrodeless conductivity sensor has a unique zero point and span. Consequently,when calibrating a sensor for the first time, always zero it according to step 1. Zeroing provides the best pos-sible measuring accuracy.

NOTE: An in-progress calibration can always be aborted by pressing the ESC key. After the “ABORT: YES?”screen appears, do one of the following:

• Press ENTER key to abort. After the “CONFIRM ACTIVE?” screen appears, press ENTER key toreturn analog outputs and relays to their active states (MEASURE screen appears).

• Use ×× or ØØ key to choose “ABORT: NO?” screen, and press ENTER key to continue calibration.

1. Zero the sensor if it is being calibrated for the first time. If not, disregard this step and proceed with step 2.

Zeroing Tip! If at any time during zeroing, the “ZERO: CONFIRM FAILURE?” screen appears, pressENTER key to confirm. Then, use the ×× or ØØ key to select between “CAL EXIT” or “CAL REPEAT” anddo one of the following:

D. With “SENSOR” line selected, press ENTER key to display .

E. Use ØØ key to select “ZERO” line and press ENTER key to display . PressENTER key again to “hold” the analog outputs and relays at their present states during zeroing. (Out-puts can also be transferred to preset values or allowed to remain active.)

F. With the dry sensor held in air and the “ZERO: IN DRY AIR?” screen displayed, press ENTER key tostart the automatic zeroing.

G. After the “ZERO: CONFIRM ZERO OK” screen appears, press ENTER key to end zeroing.

H. After the “ZERO: CONFIRM ACTIVE?” screen appears, press ENTER key to return the analog outputsand relays to their active states (MEASURE screen appears).

2. Prepare a reference solution that has a conductivity value within the measuring range that you set for theanalyzer. For best accuracy, the conductivity reference solution value should be near the typical measuredprocess value. For solution preparation details, refer to step 1 and Table F in PART THREE, Section 5.3,subsection “COND CAL Method.”

3. Thoroughly rinse the clean sensor in de-ionized water. Then immerse the sensor in the prepared referencesolution. Important: Allow the sensor and solution temperatures to equalize. Depending on their tem-perature differences, this may take up to 30 minutes.

NOTE: Suspend the sensor to prevent it from touching the container. Simply laying it into the container willproduce calibration error.

Calibration Tip! If, at any time during calibration, the “COND CAL: CONFIRM FAILURE?” screen ap-pears, press ENTER key to confirm. Then, use the ×× or ØØ key to select between “CAL EXIT?” or “CALREPEAT?” and do one of the following:

• With the “COND CAL: CAL EXIT?” screen selected, press ENTER key. Then, after the “COND CAL:CONFIRM ACTIVE?” screen appears, press ENTER key to return the analog outputs and relays totheir active states (MEASURE screen appears).

SECTION 1

1.1 Capability HighlightsSensor Input

MEASURE Screen

Passcode-protectedAccess

Calibration Methods

Analog Outputs

The analyzer can be used with any GLI Model 3700E-serieselectrodeless conductivity sensor. These sensors have abuilt-in Pt 1000 RTD temperature compensator element.

The MEASURE screen (normal mode display) provides dif-ferent readouts of measured data. With the MEASUREscreen displayed, press ÕÕ or ÖÖ key to show measuredconductivity (or % concentration or TDS) on its middle line orthe corresponding measured uncompensated conductivity.

The bottom auxiliary display line, shown in reverse video,can be changed by pressing the ØØ and ×× keys to show:

• Measured temperature (°C or °F)• Analog Output 1 value (mA)• Analog Output 2 value (mA)

For security, you can enable a passcode feature to restrict ac-cess to configuration and calibration settings to authorizedpersonnel only. See PART THREE, Section 4.6 for details.

Each sensor has a unique zero point and span. Therefore,always ZERO the sensor in air if it is being calibrated for thefirst time (PART THREE, Section 5.2). Specific methods tocalibrate for sensor span are available and dependent onthe analyzer’s configured measurement (conductivity, %concentration or TDS). For calibration details, refer to Sec-tion 5.3, 5.4 or 5.5 respectively. The mA values for eachanalog output can also be calibrated (Section 5.6).

The analyzer provides two isolated analog outputs (1 and2). Each output can be set to be 0-20 mA or 4-20 mA, andassigned to represent one of these measurements:

• Measured conductivity, % concentration or TDS.• Measured temperature.

GENERAL INFORMATION



Relays

�

�

Parameter values can be entered to define the endpoints atwhich the minimum and maximum analog output values aredesired (range expand). For analog output setup details,refer to PART THREE, Section 4.4.

During calibration, both analog outputs can be selected to:

• Hold their present values (HOLD OUTPUTS)

• Transfer to preset values to operate control elementsby an amount corresponding to those values (XFEROUTPUTS)

• Remain active to respond to the measured value(ACTIVE OUTPUTS).

The analyzer may have up to four electromechanical relays,all with SPDT contacts. Each relay can be set to function asa CONTROL, ALARM, TIMER or STATUS relay. CONTROLand ALARM relays can be assigned to be driven by one ofthese measurements:


NOTE: Since TIMER and STATUS relays are driven byother criteria, the parameter assigned to these re-lays is not relevant and, therefore, disregarded.

Refer to PART THREE, Section 4.5 for relay setup details.

NOTE: When a relay is set to function as a STATUS relay,it is no longer configurable. Instead, it becomes adedicated system diagnostic-only alarm relay thatautomatically energizes when the “WARNINGCHECK STATUS” message flashes on theMEASURE screen. This occurs when the analyzerdetects a “fail” diagnostic condition. See PARTTHREE, Section 6.1 for more details.

Except for STATUS relays, during calibration the relayon/off states are affected in the same way as the analogoutputs by the “(HOLD/XFER/ACTIVE) OUTPUTS” screenselection. These relays are also held at their present on/offstates, transferred to desired preset on/off states, or remainactive to respond to measured values.



1.2 Modular Construction

1.3 RetainedConfiguration Values

1.4 AnalyzerSerial Number

1.5 EMI/RFI Immunity

The modular construction of the analyzer simplifies fieldservicing and provides electrical safety. The front door/keypad assembly uses voltages no greater than 24 VDC,and is completely safe to handle.

Opening the analyzer door accesses terminals inside theenclosure for electrical connections. Line power must beconnected to specifically designated terminals on TB3.

WARNING:

REMOVE LINE POWER BEFORE NEARING THIS AREATO AVOID ELECTRICAL SHOCK.

All user-entered configuration values are retained indefi-nitely, even if power is lost or turned off. The non-volatileanalyzer memory does not require battery backup.

A label with the analyzer model number, serial number, builddate, and other items is affixed to the top of the enclosure.

The analyzer is designed to provide protection from mostnormally encountered electromagnetic interference. Thisprotection exceeds U.S. standards and meets EuropeanIEC 801-series testing for electromagnetic and radio fre-quency emissions and susceptibility. Refer to Figure 1-1and the specifications in Section 2.1 for more information.

SECTION 1

After unpacking, it is recommended to save the shippingcarton and packing materials in case the instrument must bestored or re-shipped. Inspect the equipment and packingmaterials for signs of shipping damage. If there is any evi-dence of damage, notify the transit carrier immediately.

SECTION 2

2.1 Location

�

1. It is recommended to locate the analyzer as close aspossible to the installed sensor. The maximum allow-able distance between an installed sensor and theanalyzer depends upon the full-scale value you set forthe analyzer measuring range:

200-2000 µS/cmFull-scale Value

2000-2,000,000 µS/cmFull-scale Value

200 feet (61 m) 300 feet (91 m)

NOTE: When measuring % concentration, convert theanalyzer full-scale value to conductivity to de-termine the maximum distance.

2. Mount the analyzer in a location that is:

➥ Clean and dry where there is little or no vibration.

➥ Protected from corrosive fluids.

➥ Within ambient temperature limits (-4 to +140°F or-20 to +60°C).

CAUTION:

EXPOSING THE ANALYZER TO DIRECTSUNLIGHT MAY INCREASE THE OPERATINGTEMPERATURE ABOVE ITS SPECIFIEDLIMIT, AND DECREASE DISPLAY VISIBILITY.RECOMMENDATION: IN SEVERE CASES,USE A GLI SUN SHIELD (P/N 1000G3088-001).

2.3 Conduit HoleRequirements

�

Recommendation: Run all wiring to the analyzer in 1/2-inch, grounded metal conduits. If using only shielded ca-bles, appropriate strain reliefs or cable grips are required.(GLI offers accessory cable grips, part number 3H1091, andwatertight locknuts, part number 3H1230, for cable entries.)Seal unused cable entry holes with appropriate plugs.

NOTE: Use NEMA 4-rated (≅ IP65) fittings and plugs tomaintain the watertight integrity of the NEMA 4Xenclosure.

3.1 GLI ElectrodelessConductivity Sensor

�

To access terminals for electrical connections, open the left-hinged enclosure door by unscrewing the four fasteners.Figure 2-3 or 2-4 shows the terminal arrangement and theirdesignations.

NOTE: All terminals are suitable for single wires up to 14AWG (2.5 mm2). If the analyzer is equipped withonly relays A and B, “RELAY C” and “RELAY D”terminals will not function (all relay designations arealways shown).

Wiring Tip! To comply with European Community (CE)electromagnetic compatibility requirements, follow thesegeneral wiring guidelines:

1. Keep all cable shields as short as possible insidethe analyzer, and connect them to the ground termi-nals provided. Performance may be improved byusing cable glands that enable the shield to directlycontact the analyzer chassis.

2. Use Steward ferrite 28 B0590-000 or equivalent onthe sensor cable -- two turns required.

3. In harsh conducted RF conditions, connect the earthground of the analyzer to a local, known earthground source.

NOTE: For easier wiring, connect line power and relay out-puts through the back conduit holes before connectingsensor and analog outputs through the front holes.

All GLI Model 3700E-series electrodeless conductivity sen-sors have a built-in Pt 1000 ohm RTD temperature elementfor automatic temp. comp. and to measure temperature.

Wiring Tip! Route the sensor cable in 1/2-inch,grounded metal conduit to protect it from moisture,electrical noise, and mechanical damage.

For installations where the distance between sensor andanalyzer exceeds the sensor cable length, indirectlyconnect the sensor to the analyzer using a junction boxand interconnect cable.

ELECTRICAL CONNECTIONS



� NOTE: Do not route the sensor cable in any conduit con-taining AC or DC power wiring (“electrical noise”may interfere with the sensor signal). Also, alwaysre-calibrate the system when the cable length be-tween sensor and analyzer changes.

3.2 Analog Outputs

�

�

Two isolated analog outputs (1 and 2) are provided. Eachoutput can be set to be 0-20 mA or 4-20 mA, and assignedto represent one of the following:


The outputs are isolated from the inputs and earthground, but not from each other. For output configurationdetails, see PART THREE, Section 4.4.

Wiring Tip! Use high quality, shielded instrumentationcable for connecting the analog outputs. To protect theoutput signal from EMI/RFI, connect the cable shield to:

� The grounding strip at bottom of case (5 open holes,Fig. 2-3) for analyzers with “B” prefix serial number.

� The “ground symbol” Terminal 1 on TB1 (Figure 2-4)for analyzers with no letter prefix serial number.

Each 0/4-20 mA output can drive a load of up to 600 ohms.

• Output 1: Connect the load to Terminals 2 and 3 on TB1,matching polarity as indicated.

• Output 2: Connect the load to Terminals 4 and 5 on TB1,matching polarity as indicated.

NOTE: When using the HART communication option, adigital signal is encoded onto the 4-20 mA analogOutput 1 signal. In a HART point-to-point wiringconfiguration, Output 1 remains available for normaluse. However, in a HART multi-drop wiring configu-ration, Output 1 becomes dedicated to that functionand cannot be used. See PART THREE, Section 8for more HART communication information.



3.3 Relay Outputs The analyzer may be equipped with up to four electrome-chanical relays. For relay setup details, see PART THREE,Section 4.5.

CAUTION:

DO NOT EXCEED THE CONTACT RATING FOREACH RELAY (5A 115/230 VAC). WHEN SWITCHINGLARGER CURRENTS, USE AN AUXILIARY RELAYSWITCHED BY THE ANALYZER RELAY TO EXTENDANALYZER RELAY LIFE. WHEN USING RELAYOUTPUTS, MAKE SURE THAT LINE POWER WIRINGCAN ADEQUATELY CONDUCT THE CURRENTDRAW OF THE SWITCHED LOAD(S).

Up to four sets of SPDT relay outputs (Relays A, B, C, andD) are provided at Terminals 1 through 12 on TB2. The re-lay outputs are not powered. The line power used topower the analyzer may also be used to power control/alarm devices with these relay contacts. See Figure 2-7 fora general wiring arrangement. Always check control wiringto insure that line power will not be shorted by the relayswitching action, and that wiring conforms to local codes.

WARNING:

MAKE SURE LINE POWER IS NOT PRESENT WHILECONNECTING WIRES TO THE TB2 RELAY TERMINALS.

FIGURE 2-7Connecting Control/Alarm Device(s) to Electromechanical Relay(s)



3.4 Closed ContactTTL Input

�

The analyzer TTL input feature enables you to convenientlyhold or transfer analog outputs and CONTROL and ALARMrelays. How the TTL input feature functions depends onwhat output state (HOLD, XFER or ACTIVE) was selectedduring the last calibration:

• If HOLD was selected, the TTL input will hold analogoutputs at their last measured values, and hold relaysin their present “on/off” states.

• If XFER (transfer) was selected, the TTL input willtransfer analog outputs to their user-entered presetvalues, and transfer relays to their user-entered preset“on/off” states.

• If ACTIVE was selected, the TTL input becomesdisabled keeping the analog outputs and relays activeso they can respond to the measured value.

To apply a TTL hold or transfer, either locally or remotelyconnect TTL Terminal 9 to Terminal 10 on TB1. When thisconnection is broken, the applied hold or transfer releases.

NOTE: The TTL input hold feature can be affected by threeother methods used to hold the analog outputs andrelays, which are listed in order of precedence:

1. Selected Calibration Output State: The out-put state (HOLD, XFER or ACTIVE) selectedduring a calibration always takes precedenceover the TTL input. If the TTL input was oper-ating, it will be re-applied after calibration (oraborted calibration) and will function accordingto the last selected output state.

2. TEST/MAINT Menu HOLD OUTPUTS Func-tion: The TEST/MAINT hold always takesprecedence over the TTL input. If the TTL inputwas operating, it will be re-applied after theTEST/MAINT hold is released.

3. Active TIMER Relay: An applied TTL inputalways takes precedence over a TIMER relay.When the TTL input is applied, it suspends theTIMER relay countdown until the TTL input isreleased. Thereafter, the TIMER relay resumesits countdown from the point where it was sus-pended.



3.5 Line Power

�

�

Refer to the following appropriate figures and connect linepower to TB3 terminals using the standard three-wire con-nection arrangement. Use wiring practices whichconform to local codes (example: National Electric CodeHandbook in the U.S.A.).

WARNING:

REMOVE LINE POWER WHILE CONNECTING LINEPOWER WIRES TO THE TB3 TERMINALS. ALSO,USE ONLY THE STANDARD THREE-WIRE CONNEC-TION ARRANGEMENT FOR SINGLE-PHASE LINEPOWER TO PREVENT AN UNSAFE CONDITION, ANDTO ENSURE PROPER ANALYZER OPERATION.

NOTE: In all cases, connect the line power cable groundwire (usually green) to:

� The grounding strip at bottom of case (5 openholes -- Figures 2-8, 2-9 or 2-10) for analyzerswith “B” prefix serial number.

� The “ground symbol” terminal 1 on TB3 (Figures2-11, 2-12 or 2-13) for analyzers with no letterprefix serial number.

The “115” and “230” voltage circuits are protected with in-ternal, board-mounted slow-blow fuses.

NOTE: For 230 volt split phase line power, be sure to con-form to local codes with regard to fusing the 115volt line connected to the “N” terminal.

PART THREE - OPERATION SECTION 1 - USER INTERFACE


P A R T T H R E E - O P E R A T I O N

SECTION 1

1.1 Display

1.2 Keypad

The user interface consists of an LCD display and a keypadwith MENU, ENTER, ESC, ÕÕ, ÖÖ, ××, and ØØ keys.

By using the keypad, you can display three types ofscreens:

• MEASURE Screen: The normal display mode showsmeasured values. Pressing the ÕÕ or ÖÖ key while viewingthe MEASURE screen alternately shows the measuredconductivity (or % conc. or TDS) and the correspondinguncompensated conductivity.

Pressing the ØØ or ×× key changes the bottom line (in re-verse video) of the MEASURE screen to show measuredtemperature (°C or °F), or analog Output 1 or 2 mA value.

An example of a typical MEASURE screen is:

��

On the MEASURE screen’s top line, Relay A, B, C, and Dannunciators will appear when their relay operationalstate changes. When a relay overfeed timer is used and ithas “timed out,” the respective relay annunciator continu-ously blinks until the overfeed condition is resolved.

• MENU Screens: These top-level and lower-level (sub-menu) screens within the three main branches of themenu tree are used to access edit/selection screens forconfiguration. (EXIT screens at the end of each menubranch enable you to move up one level in the menu treeby pressing the ENTER key. This is functionally the sameas pressing the ESC key.)

• Edit/Selection Screens: These screens enter values/choices to calibrate, configure, and test the analyzer.

The keypad enables you to move throughout the analyzermenu tree. The keys and their related functions are:

USER INTERFACE



1. MENU key: Always displays the top of the menu tree(“MAIN MENU” selection screen). To display the top-levelmenu screen for a desired main branch (CALIBRATE,CONFIGURE or TEST/MAINT), use ØØ and ×× keys to se-lect corresponding line, and press ENTER key. (This keyalso “aborts” the procedure to change values/selections.)

2. ENTER key: Pressing this key does two things: it dis-plays submenu and edit/selection screens, and it enters(saves) configuration values or selections.

3. ESC key: Always takes the display up one level in themenu tree. (Example: With “MAIN MENU” branch se-lection screen displayed, pressing ESC key once takesdisplay up one level to MEASURE screen.) This key canalso “abort” the procedure to change a value or selection.)

4. ÕÕ and ÖÖ keys: Depending on the type of displayedscreen, these keys do the following:

• MEASURE Screen: Alternately selects betweenmeasured conductivity (or % conc. or TDS) and thecorresponding uncompensated conductivity.

• Menu Screens: These keys are non-functional.

• Edit/Selection Screens: “Coarse” adjusts thedisplayed numerical value/choice.

5. ×× and ØØ keys: Depending on the type of displayedscreen, these keys do the following:

• MEASURE Screen: Changes the bottom reversevideo display line to show the measuredtemperature or the mA value of Output 1 or 2.

• Menu Screens: Moves reverse video cursor up ordown respectively to select a displayed line item.

• Edit/Selection Screens: “Fine” adjusts numericalvalue, enclosed by parenthesis, up or downrespectively or moves up or down respectivelybetween choices enclosed by parenthesis.

FIGURE 3-1 Analyzer Keypad



1.3 MEASURE Screen(normal display mode)

�

The MEASURE screen is normally displayed. Pressing theMENU key temporarily replaces the MEASURE screen withthe “MAIN MENU” branch selection screen. Using the key-pad, you can then display other screens to calibrate,configure or test the analyzer. If the keypad is not usedwithin 30 minutes, except during calibration and whileusing specific analyzer test/maintenance functions, thedisplay will automatically return to the MEASUREscreen. To display the MEASURE screen at any time, pressthe MENU key once and then the ESC key once.

Pressing the ÕÕ or ÖÖ key alternately displays the measuredconductivity (or % concentration or TDS) and the corre-sponding measured uncompensated conductivity on thedisplay’s main middle line:

Pressing the ØØ or ×× key with the MEASURE screen dis-played scrolls its bottom reverse video line to show themeasured temperature or the mA value of Output 1 or 2 asillustrated by these MEASURE screen examples:

NOTE: When the analyzer returns to its normal MEASUREscreen mode, the appearing readout is always theversion last selected. Note that these MEASUREscreen examples show “BASIN 1” notations on theirtop lines, illustrating the analyzer notation feature.To create your own notation, refer to PARTTHREE, Section 4.2, subheading “ENTER NOTE(top line of MEASURE screen).”

When a measured value is beyond the analyzer measuringrange, a series of “ + ” or “ - ” screen symbols appear,respectively indicating that the value is above or belowrange.

6. With the desired BUILT-IN chemical table choice dis-played, press ENTER key to enter this selection.

Creating USER-DEFINED Concentration Table

If the solution being measured does not match any BUILT-IN chemical table, create a USER-DEFINED table to con-vert measured conductivity into displayed % concentration.

NOTE: A USER-DEFINED table must contain at least twodata points (Pt. 1 and Pt. 2) but can have up to tenpoints. (More points improve measuring accuracy.)Each point must have a conductivity value coordi-nate (shown as X) and a corresponding %concentration value coordinate (shown as Y). Theconductivity values and range are shown in unitsselected by the “DISPLAY COND FORMAT”screen. Conductivity values for each successivedata point must increase. Concentration values,shown in their selected 99.99% or 200.0% displayformat, must be different from each other and al-ways entered in either increasing or decreasingorder. (The table must be monotonic; that is, asconductivity values increase, concentration valuesmust always increase or decrease.)

The analyzer default USER-DEFINED concentra-tion table is:

DataPoint

Conductivity Value(X Coordinate)

% Concentration Value(Y Coordinate)

Pt. 1 0 µS/cm 0.00%

Pt. 2 2000 µS/cm 99.99%

To create your own USER-DEFINED table, edit thisdefault table and, if needed, add more points.

Recommendation: Before entering values, plan ahead anddetermine the conductivity and corresponding % concentrationvalues for each data point in your table. Use Table B to con-veniently organize and note your specific table entry values:

TEMP TABLE Compensation Setup

When special temperature compensation is required, youcan create your own temperature table to define the tem-perature compensation curve.

NOTE: The TEMP TABLE must contain at least two datapoints (Pt. 1 and Pt. 2) but can have up to tenpoints. (More points improve compensation accu-racy.) Each point must have of a temperature valuecoordinate (shown as X) and a corresponding ratiocoordinate (shown as Y). Temperature values mustbe between 0.0 and 200.0°C (or 32.0 and 392.0°F).Each entered temperature value must be differentfrom all others. Ratio values, which can be thesame, are unit-less and must be between 0.00 and99.99.

Use this equation to calculate the ratio value foreach corresponding temperature value:

Ratio Value (for each Cond. Value at Ref. Temp.corresponding temperature) Cond. Value at Noted Temp.

Example: Suppose the uncompensated or rawconductivity values are 100 mS/cm at a 25°C refer-ence temperature, 120 mS/cm at 50°C, and 70mS/cm at 15°C. Using this equation, ratio values foreach of the corresponding temperatures are:

For 25°C, ratio value = 100 ÷ 100 or 1.00For 50°C, ratio value = 100 ÷ 120 or 0.83For 15°C, ratio value = 100 ÷ 70 or 1.43

The analyzer default TEMP TABLE is:

DataPoint

Temperature Value(X coordinate)

Corresponding RatioValue (Y coordinate)

Pt. 1 0.0°C 1.00

Pt. 2 100.0°C 1.00

To create your own TEMP TABLE, edit this defaulttable and, if needed, add more data points.

Recommendation: Before entering values, plan ahead anddetermine the temperature and ratio values for each datapoint in your table. Use Table C to conveniently organizeand note your table entry values:

SET FILTER Time

SelectPULSE SUPPRESS

(on/off)

A time constant (in seconds) can be set to filter or “smoothout” the sensor signal. A minimum value of “0 seconds” hasno smoothing effect. A maximum value of “60 seconds” pro-vides maximum smoothing. Deciding what sensor signalfilter time to use is a compromise. The higher the filter time,the longer the sensor signal response time will be to achange in the actual process value.

1. With the screen displayed, use ØØ keyto select the “SET FILTER” line.


. Use arrow keys to adjust the dis-played value to the desired filter time, and pressENTER key to enter the value.

Sometimes an external interference may occasionally causethe measurement system to provide unstable readings.Common causes include entrained gas bubbles in the proc-ess, and electromagnetic interference (EMI or “electricalnoise” pulses). The analyzer has a pulse suppression fea-ture to counteract this condition and stabilize readings.Example: Suppose the analyzer reading is steadily showing1880 mS/cm, then suddenly jumps to 1950 mS/cm for a fewseconds, and returns to 1880 mS/cm. By turning on thisfeature, the analyzer will perceive this as a temporary up-set, “suppressing” most of this pulse change and providinga smoother measurement reading.

1. With the screen displayed, use ØØ keyto select the “PULSE SUPPRESS” line.

2. Press ENTER key to display . UseØØ and ×× keys to view both choices (OFF or ON). Withthe desired choice displayed, press ENTER key to en-ter this selection.

GLI tests each sensor to provide a unique, certified tem-perature T FACTOR because:

• Temperature greatly affects conductivity measurementaccuracy.

• The inherent ohm value of the Pt 1000 RTD temperatureelement varies slightly from sensor to sensor, affectingtemperature measurement accuracy.

SPECIAL CASE -- ALTERED SENSOR CABLE LENGTH

Changing the standard 20 ft. (6 m) sensor cable length, byshortening it or adding an interconnect cable, affects tempera-ture measuring accuracy. The GLI-certified T FACTOR is basedon standard cable length. To compensate for altered cablelength measuring error, change the certified T FACTOR entry:

• Shortened Sensor Cable: To increase the analyzer tempera-ture reading to match the known solution temperature,decrease the T FACTOR by 3.85 ohms for each °C difference.

• Added Interconnect Cable: To decrease the analyzer tem-perature reading to match the known solution temperature,increase the T FACTOR by 3.85 ohms for each °C difference.

Example: Suppose the known solution temperature is 50°C andthe analyzer reads 53°C due to interconnect cable resistance.Multiply the 3°C difference by 3.85 ohms to get 11.55. Then in-crease the sensor T FACTOR by adding 11.55 to it and enteringthat value. If, due to a shortened sensor cable, the analyzer wasreading 3°C less than the known solution temperature you woulddecrease the sensor T FACTOR by subtracting 11.55 from it.

The analyzer provides two isolated analog outputs (1 and2). During calibration, the analog outputs can be held,transferred to a preset mA value or remain active. Duringnormal measurement operation, the analog outputs can beheld at their last measured values:

• For up to 30 minutes be selecting the “HOLDOUTPUTS” line in the TEST/MAINT menu andpressing the ENTER key.

• For an indefinite period by locally or remotelyconnecting the TTL input Terminals 9 and 10 on TB1.

• By an activated TIMER relay for its enteredDURATION and OFF DELAY time periods(1-999 seconds each).

The output state selected during calibration (HOLD, XFERor ACTIVE) always takes precedence over an applied TTLinput hold/transfer and/or TIMER relay hold. For more de-tails on order of precedence for hold functions, refer toPART TWO, Section 3.4.

From the moment output hold is initiated (during calibration,from TEST/MAINT menu or by TTL input), the elapsed timeINTERVAL or DURATION countdown for a TIMER relay istemporarily suspended. Also, any TIMER relay countingdown DURATION time is turned off. When output hold isreleased, a TIMER relay resumes its INTERVAL orDURATION countdown from the suspended time. When aTIMER relay is counting down DURATION time, both out-puts are temporarily held until after the preset DURATIONtime (and OFF DELAY time, if used) elapses.

SET FUNCTION Mode(alarm, control,status or timer)

�

Each relay can be selected to function as a:

• ALARM relay (with separate high and low alarm pointsand deadbands) that operates in response to theselected measured value.

• CONTROL relay (with phasing, setpoint, deadband,and overfeed timer) that operates in response to theselected measured value.

• STATUS relay that is not configurable. It is a dedicatedsystem diagnostic-only alarm relay that automaticallyenergizes when the “WARNING CHECK STATUS”message flashes on the MEASURE screen. This occurswhen the analyzer detects a sensor or analyzer “fail”diagnostic condition (see PART THREE, Section 6.1 fordetails).

• TIMER relay that is intended to control a device on atimed basis. A TIMER relay activates after an enteredINTERVAL time (up to 999.9 minutes) expires. TheTIMER relay remains on for the entered DURATIONtime (up to 999 seconds).

NOTE: When a TIMER relay is counting downDURATION time, both analog outputs and allALARM and CONTROL relays are automati-cally “held” to ensure that connected devicesare not disrupted by any upset condition theTIMER relay operation may cause. An OFFDELAY time (1-999 seconds) can be entered todefine how long after the TIMER relay turns offthat the outputs and relays will remain held,providing time for any upset condition to stabilize.

From the moment output hold is initiated (during cali-bration, from TEST/MAINT menu or by TTL input), theelapsed time INTERVAL or DURATION countdown fora TIMER relay is temporarily suspended. Also, anyTIMER relay counting down DURATION time is turnedoff. When output hold is released, a TIMER relay re-sumes its INTERVAL or DURATION countdown fromthe suspended time.

Table D -- RELAY CONFIGURATION SETTINGS

Setting Description

For ALARM Relay

Low Alarm Sets the value at which the relay will turn on inresponse to decreasing measured value.

High Alarm Sets the value at which the relay will turn on inresponse to increasing measured value.

LowDeadband

Sets the range in which the relay remains on after themeasured value increases above the low alarm value.

HighDeadband

Sets the range in which the relay remains on after themeasured value decreases below the high alarm value.

Off Delay Sets a time (0-300 seconds) to delay the relay fromnormally turning off.

On Delay Sets a time (0-300 seconds) to delay the relay fromnormally turning on.

For CONTROL Relay

Phase A “high” phase assigns the relay setpoint to respondto increasing measured value; conversely, a “low”phase assigns the relay setpoint to respond to de-creasing measured value.

Setpoint Sets the value at which the relay will turn on.

Deadband Sets the range in which the relay remains on after themeasured value decreases below the setpoint value(high phase relay) or increases above the setpointvalue (low phase relay).

OverfeedTimer

Sets the time (0-999.9 min.) to limit how long the re-lay can remain “on.” For more details on overfeedtimer operation, see Part Three, Section 7.

Off Delay Sets a time (0-300 seconds) to delay the relay fromnormally turning off.

On Delay Sets a time (0-300 seconds) to delay the relay fromnormally turning on.

For TIMER Relay

Interval Sets a time (0-999.9 min.) to establish how long thetimer relay remains “off” before it turns on.

Duration Sets the time (0-999 seconds) to limit how long thetimer relay remains “on.”

Off Delay Sets a time (0-999 seconds) to establish how longafter the timer relay turns “off” that the analog outputsand alarm and control relays remain “held.”

For STATUS Relay

No settings available -- status relay cannot be configured.

NOTE: It is possible to enter values that always keep a re-lay active or inactive. To avoid this, be sure that“low” values are lower than “high” values.

When a relay is set for STATUS function, the symbol at the start of the “ACTIVATION” line de-notes that this menu item is not available.



The “off delay” and “on delay” settings, available toCONTROL or ALARM function relays, may be beneficial ineliminating process “overshoot” when there are long proc-ess pipe runs or delays in mixing.

4.6 SET PASSCODE(feature enabled ordisabled)

The analyzer has a passcode feature to restrict access toconfiguration and calibration settings to only authorizedpersonnel.

• DISABLED: With passcode feature disabled, all configu-ration settings can be displayed and changed, and theanalyzer can be calibrated.

• ENABLED: With passcode feature enabled, all configu-

ration settings can be displayed -- but they cannot bechanged, and the CALIBRATE and TEST/MAINT menuscannot be accessed without the passcode. When you at-tempt to change a setting in the CONFIGURE menu bypressing the ENTER key, a displayed notification re-quests passcode entry. A valid passcode entry saves thechanged setting and returns the display to the “MAINMENU” branch selection screen. An incorrect passcodeentry causes the display to momentarily show an errornotification before returning to the “MAIN MENU” branchselection screen. There is no limit on attempts to enter avalid passcode.

The passcode is factory-set to “3456.” It cannot be changed.

PART THREE - OPERATION SECTION 5 - ANALYZER CALIBRATION


SECTION 5

5.1 Important Information

�

�

Each electrodeless conductivity sensor has a unique zeropoint and span. Consequently, always zero the sensorwhen calibrating it for the first time (Section 5.2). Zeroingprovides the best possible measuring accuracy. Then cali-brate for sensor span using one of the available methods,and periodically thereafter to maintain best measurementaccuracy. Over time, some processes such as heavy slur-ries may plug the sensor hole, causing minor measurementerrors. The time between calibrations, and the rate ofmeasurement drift can vary considerably with each applica-tion and its specific conditions.

Calibration Tip! Establish a maintenance program tokeep the sensor relatively clean and the measuring sys-tem calibrated. The weekly or monthly intervals betweenperforming maintenance will be influenced by the char-acteristics of the process solution, and can only bedetermined by operating experience.

Since the inherent ohm value of each sensor’s Pt 1000RTD temperature element varies slightly, GLI tests eachelement to provide a unique, GLI-certified temperatureT FACTOR shown on a label attached to the sensorcable. If this factor was not previously entered duringconfiguration in Section 4.2, subheading “SET T FACTOR,”enter it now before zeroing or calibrating to providebest possible measuring accuracy.

NOTE: When the passcode feature is enabled (Section4.6), you must successfully enter the passcodebefore attempting to calibrate the analyzer.

An in-progress calibration can always be abortedby pressing the ESC key. After the “ABORT: YES?”screen appears, do one of the following:

• Press ENTER key to abort. After the “CONFIRMACTIVE?” screen appears, press ENTER key toreturn the analog outputs and relays to their ac-tive states (MEASURE screen appears).

• Press ×× or ØØ key to choose “ABORT: NO?” screen,and press ENTER key to continue calibration.

5.2 ZERO Procedure(first-time sensorcalibration only)

In addition to zeroing and calibrating for sensor span, youalso can calibrate the analyzer analog output (1 and 2) mAvalues. Refer to Section 5.6 for details.

Zeroing/Calibration Tip! If a “CONFIRM FAILURE?” screenappears during zeroing or calibration, press ENTER keyto confirm. Then, use ×× or ØØ key to select between“CAL: EXIT” or “CAL: REPEAT” and do one of the following:

• With “(CAL: EXIT)” screen selected, press ENTERkey. After the “CONFIRM ACTIVE?” screen appears,press ENTER key to return analog outputs and relaysto their active states (MEASURE screen appears).

• With “(CAL: REPEAT)” screen selected, press ENTERkey to repeat zeroing or calibration.

Zero the sensor if it is being calibrated for the first time. Ifnot, disregard this subsection and proceed with sensorspan calibration (Section 5.3, 5.4 or 5.5).

1. Make sure that the sensor is dry before zeroing.

4. With the “SENSOR” line selected, press ENTER key todisplay one of these screens:

(Displayed screen depends on selected measurement.)

5. In all cases, use ØØ key to select the “ZERO” line, and

press ENTER key to display . Use ×× orØØ key to view the three states that the analog outputs(and relays) can be in during zeroing:

COND CAL Method

• HOLD OUTPUTS: Holds their present values.• XFER OUTPUTS: Transfers to preset values.• ACTIVE OUTPUTS: Responds to measured values.

With the desired choice displayed, press ENTER key toenter this selection.

6. With the dry sensor held in air and the “ZERO: IN DRYAIR?” screen displayed, press ENTER key to confirmthis and start automatic zeroing.

7. After the “ZERO: CONFIRM ZERO OK?” screen ap-pears, press ENTER key to end zeroing.

8. After the “ZERO: CONFIRM ACTIVE?” screen appears,press ENTER key to return the analog outputs and re-lays to their active states (MEASURE screen appears).

This completes zeroing the sensor.

After zeroing the sensor (first-time sensor calibration only),calibrate for sensor span using one of these methods:

• COND CAL Method: This method requires removingthe sensor from the process, immersing it into a con-ductivity reference solution, and entering a temp.compensation reference temperature, linear % per °Cslope, and known conductivity reference solution value.

• SAMPLE CAL Method: This method allows keepingthe sensor installed in the process, but requires you toobtain a process sample, determine its value by laboratoryanalysis or comparison reading, and enter that value.

1. Prepare the conductivity reference solution using yournormal method. Its value should be near the typicalmeasured process value for best accuracy. When thevalue is relatively low (between 200 and 100,000 mi-croSiemens/cm), you may want to use the data in TableF on the next page to prepare the reference solution.Add the listed grams of pure, dried NaCl to one liter ofhigh purity, de-ionized, CO2-free water that is 25°C toobtain the listed conductivity. Solution conductivity canbe decreased by dilution with de-ionized water.

2. Thoroughly rinse the clean sensor in de-ionized water.Then immerse the sensor in the prepared referencesolution. Important: Allow the sensor and solutiontemperatures to equalize. Depending on their tem-perature differences, this may take up to 30 minutes.

NOTE: Suspend the sensor to prevent it from touchingthe container. Simply laying it into the containerwill produce calibration error. If the sensor istee-mounted, use a smaller container. Ideally,convert a tee of the same size and material asthe mounting tee into a calibration container bysealing two of its ends.

After zeroing the sensor (first-time sensor calibration only),calibrate for sensor span using one of these methods:

• CONC CAL Method: This method requires you to im-merse the sensor into a prepared % concentrationreference solution of known value, or to keep the sen-sor installed in the process while obtaining a processsample. When keeping the sensor installed, determinethe process value by laboratory analysis or comparisonreading. In either case, enter the known reference solu-tion or sample % concentration value.

• COND CAL Method: This method requires you to re-move the sensor from the process, immerse it into aconductivity reference solution, and enter a tempera-ture compensation reference temperature, linear % per°C slope, and known reference solution value. The

conductivity reference solution should have an equiva-lent, uncompensated value that corresponds with thenormal % concentration value of the process.

1. Depending on the situation, do one of the following:

� When Keeping Sensor Installed:

Obtain a sample of the process solution and deter-mine its value using laboratory analysis or arecently calibrated portable meter.

5.5 TDS Calibration

�

When the analyzer is set to measure % concentration butyou want to calibrate using a conductivity reference solu-tion, please refer to Section 5.3, subsection “COND CALMethod” and follow steps 1 through 14.

When the analyzer is set to measure TDS, only the “TDSCAL” method is available for sensor span calibration. Thismethod requires you to immerse the sensor into a preparedTDS reference solution of known ppm value, or to keep thesensor installed in the process while obtaining a processsample. In either case, enter the known reference solutionor sample ppm value.

1. Depending on the situation, do one of the following:

� When Keeping Sensor Installed:

Obtain a sample of the process solution and deter-mine its value using laboratory analysis or arecently calibrated portable meter.

� When Using a Reference Solution:

A. Prepare a TDS reference solution using yournormal method. To achieve accurate calibra-tion, the reference solution must have thesame chemical composition as the process.Also, its value should be near the typical meas-ured process value. When the value is relativelylow (between 100 and 72,710 ppm NaCl), youcan prepare the reference solution using theinformation from step 1 and Table F in Section5.3, subsection “COND CAL Method.”

B. Thoroughly rinse the clean sensor in de-ionizedwater. Then immerse the sensor in the preparedreference solution. Important: Allow the sen-sor and solution temperatures to equalize.Depending on their temperature differences,this may take up to 30 minutes.

NOTE: Suspend the sensor to prevent it fromtouching the container. Simply laying it

7.1 Why Use anOverfeed Timer

7.2 Configuring RelayOverfeed Timers

7.3 Overfeed Timer“Timeout” Operation

7.4 Resetting OverfeedTimers

7.5 Interactions with OtherAnalyzer Functions

The useful relay overfeed timer feature, only available to aCONTROL relay, is described in more detail in this section.

Suppose that you configure a CONTROL relay with a highphase to operate in response to increasing measured value.The CONTROL relay will then turn on whenever the meas-ured value exceeds its preset setpoint. When the measuredvalue decreases below the setpoint by an amount you pre-set (the deadband setting), the relay will turn off. But what ifa damaged sensor or a process upset condition keeps themeasured value above the setpoint or deadband setting?The control element (valve, pump, etc.) switched by thatrelay would then continue to operate. Depending on the ap-plication control scheme, this may excessively dispensecostly chemical additives or overly drain or divert the proc-ess. Also, the control element itself could be damaged dueto excessive continuous or unusual operation such as apump that is running dry. The useful overfeed timer pre-vents undesirable conditions like these from happening. Itrestricts how long the relay and its connected control ele-ment will remain on regardless of conditions.

To set a relay overfeed timer, use its respective configura-tion menu screen. The time you set to restrict how long therelay stays on (0-999.9 minutes) should be just enough toprovide acceptable results. An excessive setting may wastechemicals or the process itself. Initially, set this time as anestimate. Then, by experimenting and observing the re-sponse, periodically “fine tune” to optimize the setting.

When a CONTROL relay is on and its overfeed timer “timesout,” its annunciator will blink. This indicates that the relayis now off and will remain off until you manually reset theoverfeed timer. After reset, the relay annunciator stopsblinking. (All overfeed timers are reset simultaneously.)

To manually reset all relay overfeed timers, please refer toPART THREE, Section 6.3.

A relay overfeed timer can, and often will, interact with otheranalyzer functions while those functions are in use. Table Gon the next page explains these common overfeed timerinteractions.

PART THREE - OPERATION SECTION 8 - HART OPTION


SECTION 8

8.1 Introduction

�

Your GLI analyzer may be equipped with the HART® FieldCommunications Protocol option for two-way digital com-munication. This option enables you to configure theanalyzer and retrieve its measured data by using:

• A hand-held terminal such as a HART CommunicatorModel 275 (or other HART®-compatible configurator)containing GLI Device Specific Command sets in itsnon-volatile memory

• An IBM-compatible PC with appropriate HART® FieldCommunications Protocol software

NOTE: Any generic hand-held terminal can also communi-cate with a GLI HART-equipped analyzer, withlimited operability, using HART Protocol UniversalCommands and/or Common Practice Commands.

The hand-held terminal or PC must be connected to the ana-lyzer 4-20 mA analog Output 1 signal anywhere along thecircuit wiring. See subsections 8.3 or 8.4 for more details.

8.2 Analyzer OperatingModes forHART Network

�

HART enables simultaneous analog and digital communi-cation. The analyzer can be operated in the SINGLE MODEor MULTI-DROP mode on a HART network. An analyzerswitch setting selects the mode.

When the analyzer is set to operate in the SINGLE (Point-to-Point) MODE, as set by the factory, HART preserves theintegrity of the 4-20 mA analog Output 1 signal for normaluse while enabling two-way digital communication betweena single analyzer and querying device(s). The analog signalrepresents the measured process value. The digital signal,encoded onto the analog signal, can be used to:

• Perform all available analyzer functions (presently, onlywhen using a HART Communicator Model 275).

• Calibrate, configure and acquire all analyzer settings,and retrieve analog output values and measuredprocess value(s).

• Assign device preferences such as a tag, descriptor,message, and date field (for example, to show lastcalibration date).

• Acquire device information such as analyzer modelnumber, identification number, distributor, etc.

• Acquire HART information including polling addressand number of required preambles.

Your HART-equipped “smart” GLI analyzer can also be se-lected to operate in an all-digital MULTI-DROP mode. Thisenables you to connect multiple analyzers -- all set forMULTI-DROP operating mode -- to the querying device(s)using a common 4-20 mA output cable, creating an efficientmulti-analyzer two-way digital communications network.

NOTE: In the MULTI-DROP mode, the 4-20 mA analogOutput 1 signal of each analyzer becomes dedi-cated only for network use and cannot be used as anormal output.

Set for either SINGLE MODE or MULTI-DROP operation,the GLI analyzer is always a “slave,” responding to com-mands received from the “master.” The master can be ahand-held terminal or an IBM-compatible computer withHART-capable software (or software including GLI DeviceSpecific Command sets). The GLI analyzer never initiates acommand sequence, but always responds to commandsfrom the master. Up to two master devices may be



�

8.3 SINGLE MODE(Point-to-Point)Wiring Arrangement

connected to each HART loop. Typically, the primary masteris a management system or a PC, while the secondarymaster is usually a hand-held terminal.

NOTE: All HART-equipped GLI analyzers are supplied withtheir SINGLE MODE/MULTI-DROP switch set tothe SINGLE MODE position to preserve analogOutput 1 for normal use.

To set the analyzer operating mode for the HART network,locate the SINGLE MODE/MULTI-DROP switch (Figure 3-2)and set it to the desired mode:

• SM (left position) for SINGLE MODE• MD (right position) for MULTI-DROP mode.

FIGURE 3-2 Location of SINGLE MODE/MULTI-DROP Switch(HART-equipped analyzers only)

When the GLI analyzer is set to operate in the SINGLE(Point-to-Point) MODE on a HART network, the master(s) isintended to communicate with only a single analyzer. Referto Figure 3-3 and connect all devices, including up to twomasters, to the 4-20 mA analog Output 1 signal.

FIGURE 3-3 HART SINGLE MODE (Point-to-Point) Wiring Arrangement (for single analyzer)



8.4 MULTI-DROPWiring Arrangement

�

When the GLI analyzer is set to operate in the MULTI-DROP mode on a HART network, the master(s) is intendedto communicate with multiple analyzers.

NOTE: When analyzers are operated in the MULTI-DROPmode, the 4-20 mA analog OUTPUT 1 signal ofeach analyzer is dedicated only for network use --not its normal use. (During startup, each analyzer isassigned a non-zero polling address, causing itsOutput 1 to automatically provide a constant 4 mAsignal.) Each analyzer’s analog OUTPUT 2, how-ever, remains available for normal use.

1. Make sure the SINGLE MODE/MULTI-DROP switch ofeach analyzer is set to the MD (right) position.

2. Refer to Figure 3-4 and connect the 4-20 mA analogOutput 1 signal of each analyzer in parallel on onecable, matching polarity as shown.

3. Connect an appropriate-sized power supply in parallelwith the analog Output 1 signal, matching polarity asshown.

4. Up to two masters can be connected to the 4-20 mAanalog Output 1 signal cable.

1.3 Replacing Relays

If a measurement problem exists and you suspect the sen-sor cable, inspect it for physical damage. If an interconnectcable is used, disconnect the cable at both ends (sensorand analyzer) and, using an ohmmeter, check its wires forcontinuity and internal shorts.

The analyzer is equipped with two board-mounted fuses(type T slow-blow; 5 mm x 20 mm size). Fuse values areshown next to each fuse (Figure 2-3 or 2-4). The fusesprotect the 115 and 230 volt line power circuits.

WARNING:

DISCONNECT LINE POWER TO AVOID THEPOSSIBILITY OF ELECTRICAL SHOCK.

1. After disconnecting line power, open the analyzer doorand locate the fuses (shown in Figure 2-3 or 2-4).

2. Remove the blown fuse and replace it with a GLI fuseor an equivalent. Refer to PART FIVE -- Spare Parts --for GLI fuse kit part number.

3. Reconnect line power and close the analyzer door.

The analyzer relays are soldered into a complex, multi-layered circuit board. To avoid the possibility of damagingthis board while attempting to replace a relay:

• Simply return the complete analyzer to the GLI Cus-tomer Service Dept. or your local factory-authorizedservice organization for relay replacement.

�

2.3 Avoiding ElectricalInterference

�

To maintain measurement accuracy, periodically clean thesensor. Operating experience will help you determine theintervals between cleanings (typically once a month). Usethe recommended cleaning procedure described in the GLIelectrodeless conductivity sensor operating manual.

Depending on application circumstances, periodically cali-brate the analyzer to maintain measurement accuracy.

Maintenance Tip! Upon startup, frequently check thesystem until operating experience can determine theoptimum time between calibrations that provides accept-able measurement results.

Calibrate the analyzer using a method described in PARTTHREE, Section 5.3, 5.4 or 5.5. Calibrating with old, con-taminated or diluted reference solution may cause measure-ment errors. Do not reuse a reference solution -- alwaysdiscard it. Note that the value of a reference solutionchanges as its temperature changes. Therefore, always al-low the temperatures of the sensor and reference solutionto equalize while calibrating.

Recommendation: Do not run the sensor cable (and inter-connect cable, if used) in the same conduit with AC or DCpower wiring. Also, connect cable shielding as recom-mended (PART TWO, Section 3.1).

Maintenance Tip! Excess cable should not be coilednear motors or other equipment that may generateelectrical or magnetic fields. Cut cables to proper lengthduring installation to avoid unnecessary inductive pickup(“electrical noise” may interfere with sensor signal).
