CONDENSED OPERATING INSTRUCTIONS

This manual contains details for all operating aspects of the instrument. The following condensed in-structions are provided to assist you in getting the instrument started up and operating as quickly aspossible. These condensed instructions only pertain to basic conductivity measurement opera-tion. To measure resistivity, TDS or a calculated Sensor A and B measurement, or to use specificfeatures of the instrument, refer to the appropriate sections in this manual for instructions.

A. CONNECTING SENSOR(S)/CONFIGURING TEMPERATURE ELEMENT(S)

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

Sensor A Wire Colors Connect To Sensor B Wire Colors Connect To

Red Terminal #1 on TB3 Red Terminal #6 on TB3Black Terminal #2 on TB3 Black Terminal #7 on TB3

Clear (inner shield wire) Terminal #3 on TB3 Clear (inner shield wire) Terminal #8 on TB3White Terminal #4 on TB3 White Terminal #9 on TB3Blue Terminal #5 on TB3 Blue Terminal #10 on TB3

Clear w/black (outer shield) Terminal #1 on TB2 Clear w/black (outer shield) Terminal #2 on TB2

NOTE: For best immunity to electromagnetic interference, connect the sensor cable’s outershield wire (clear with black band -- not its clear only inner shield wire) to a “SENSORSHIELD (OUTER)” terminal on TB2.

2. The analyzer is factory-set for automatic temperature compensation using the Pt 1000 ohm tem-perature element built into GLI contacting conductivity sensors. If you want fixed MANUALtemperature compensation, change the temperature element type to “MANUAL” and enter a tem-perature. For details, see PART THREE, Section 3.2, subheading “Select TEMP ELEMENT Type.”

NOTE: When using only one sensor, always select “MANUAL” for the unused sensor element typeto prevent a “WARNING: CHECK STATUS” message due to analyzer detecting no element.

B. CONNECTING LINE POWER

Important: Follow the instructions in PART TWO, Section 3.4 to connect line power to the analyzer.

C. CALIBRATING THE ANALYZER

The analyzer must be calibrated so that measured values will correspond to actual process values. Itcan be traditionally “wet” calibrated. However, since measured conductivity is greatly affected bysmall changes in temperature, GLI strongly recommends using its simple DRY-CAL method forhighest measuring accuracy of conductivity and temperature. Besides, DRY-CAL is actually a normalpart of configuring the sensor characteristics during initial startup, and DRY-CAL eliminates theneed for conductivity reference solutions. This method also automatically sets the analyzermeasuring range to match the inherent range of the sensor’s cell constant. For more details aboutthe benefits of DRY-CAL, refer to the “Calibration Tip!” in PART THREE, Section 4.1.

NOTE: DRY-CAL eliminates the need for periodic re-calibration! The only requirement, dependingon the application, may be to periodically clean the sensor. Only when the sensor is re-placed is it necessary to perform a new DRY-CAL calibration.

Calibration Tip! Each contacting conductivity sensor has a unique zero point and span. Conse-quently, when calibrating a sensor for the first time, always zero it according to step 1. Zeroingprovides the best possible measuring accuracy, and eliminates any discrepancy between Sensor Aand B measurement channels.

(continued on next page)



C. CALIBRATING THE ANALYZER -- (continued)

DRY-CAL, routinely attained while configuring the analyzer for sensor characteristics, requires entryof the sensor’s GLI-certified “CELL K” value and temperature “T FACTOR” which are unique for eachsensor. When using two sensors, enter each set of values using the respective sensor menu screens.

1. Zero the sensor if it is being calibrated for the first time. If not, disregard this step and performsteps 2 through 17:

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

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

• With “ZERO? (CAL REPEAT)” selected, press ENTER key to repeat zeroing.

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

B. Press MENU key to display a “MAIN MENU” screen. If the screen is notshowing, use ×× or ØØ key to display it.

C. Press ENTER key to display .

D. Press ENTER key again to display .

E. Press ØØ key once to display .

F. Press ENTER key to display .

G. Press ENTER key again to “hold” the analog outputs and relays at their present states duringzeroing. (Outputs can also be transferred to preset states or allowed to remain active.)

H. With the “ZERO: IN DRY AIR?” screen displayed and the dry sensor held in air, pressENTER key to start the automatic zeroing.

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

J. After the “ZERO: CONFIRM ACTIVE?” screen appears, press ENTER key to return theanalog outputs and relays to their active states (MEASURE screen appears).

2. Press MENU key to display .

3. Press ØØ key once to display .

4. Press ENTER key to display .

5. Press ØØ key until appears.

C. CALIBRATING THE ANALYZER -- (continued)




9. Press ENTER key again to display a cell category selection screen like . Use×× and ØØ keys to select the nominal cell category that corresponds to the sensor’s GLI-certified“CELL K” value shown on a label attached to the sensor cable or to the inside cover of its op-tional junction box. Then press ENTER key to enter the selection.

10. After the screen re-appears, press ØØ key once to display .

11. Press ENTER key to display a “CELL K” value screen like . Adjust the dis-played value to exactly match the sensor’s GLI-certified “CELL K” value. (Use ÖÖ and ÕÕ keys tocoarse adjust, and ×× and ØØ keys to fine adjust.) Then press ENTER key to enter the value.

12. After the screen re-appears, press ESC key once to display .




16. Press ENTER key to display a “T FACTOR” value screen like . Adjust thedisplayed value to exactly match the sensor’s GLI-certified “T FACTOR.” (Use ÖÖ and ÕÕ keys tocoarse adjust, and ×× and ØØ keys to fine adjust.) Then press ENTER key to enter the value.

17. After the screen re-appears, press MENU key once and then ESC key onceto display the MEASURE screen.

This completes GLI’s DRY-CAL calibration. The analyzer is now ready to measure conductivity.

To change the display format of the MEASURE screen (for example, from 0-2000 µS/cm to0.000-2.000 mS/cm), refer to PART THREE, Section 3.2, subheading “Select DISPLAY FORMAT.”

NOTE: If the values you intend to measure are above the analyzer’s set measuring range (not itsselected display format), use a different sensor that has the appropriate nominal cell con-stant. For a listing of sensor cell constants and their inherent measuring ranges, see TABLEA in PART THREE, Section 3.2, subheading “Select DISPLAY FORMAT.”

D. COMPLETING ANALYZER CONFIGURATION

To further configure the analyzer to your application requirements, use the appropriate CONFIGUREscreens to make selections and “key in” values. Refer to PART THREE, Section 3 for complete con-figuration details.

P A R T O N E - I N T R O D U C T I O N

SECTION 1

1.1 Capability HighlightsSensor Input

MEASURE Screens

Passcode-protectedAccess

Calibration Methods

The analyzer has two sensor inputs to independently moni-tor two measurement points. Each input can accept a GLIModel 3400-series enhanced performance contacting con-ductivity sensor (or another brand sensor with Pt 1000 RTDor Pt 100 RTD temperature compensator element).

The MEASURE screen (normal display mode) can providedifferent readouts of measured data. With the MEASUREscreen displayed, press ÕÕ or ÖÖ key to show:

• Measured Sensor A value (conductivity, resistivity or TDS).

• Measured Sensor A temperature (°C or °F).

• Measured Sensor B value (conductivity, resistivity or TDS).

• Measured Sensor B temperature (°C or °F).

• Analog Output 1 and Analog Output 2 values (mA).

• Measured Sensor A and B values and temperatures.

• *Calculated Sensor A and B measurement (% reject,% pass, ratio A/B, ratio B/A, diff. A-B or diff. B-A).

*The calculated measurement can only be displayed when two sen-sors are used and the analyzer has been correctly configured forCALCULATION.

For security, you can enable a passcode feature to restrictaccess to configuration and calibration settings to authorizedpersonnel only. See PART THREE, Section 3.7 for details.

It is highly recommended to calibrate the analyzer usingGLI’s simple DRY-CAL method, which eliminates the needto prepare a reference solution (PART THREE, Sections 4.2and 4.3). However, the analyzer can be traditionally “wet”calibrated (Sections 4.2 and 4.4). Each analog output mAvalue can also be calibrated (Section 4.5).

GENERAL INFORMATION



Analog Outputs

Relays

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:


• Measured Sensor A temperature.


• Measured Sensor B temperature.


*An analog output can only represent the calculated measurement whentwo sensors are used and the analyzer has been correctly configuredfor CALCULATION.

Parameter (or calculated measurement) values can be en-tered to define the endpoints at which the 0/4 mA and 20mA analog output values are desired (range expand). Foranalog output setup details, see PART THREE, Section 3.5.

During calibration, both analog outputs can be selected to:

• Hold their present values (HOLD OUTPUTS).

• Transfer to preset values to operate control elements by anamount corresponding to those values (XFER OUTPUTS).

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

The analyzer has two electromechanical relays with SPDTcontacts. Each relay can be set to function as a CONTROL,ALARM, TIMER or STATUS relay. CONTROL and ALARMrelays can be assigned to be driven by one of these:






*A relay can only be driven by the calculated measurement when two sensors areused and the analyzer has been correctly configured for CALCULATION.

NOTE: Since TIMER and STATUS relays are driven by



1.2 Modular Construction

1.3 RetainedConfiguration Values

other criteria, the parameter assigned to these re-lays is not relevant and, therefore, disregarded.

Refer to PART THREE, Section 3.6 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 5.1 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.

The modular construction of the analyzer provides electricalsafety. The front panel keypad assembly uses voltages nogreater than 24 VDC, and is completely safe to handle.

Line power must be connected to specifically designatedterminals on TB1.

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.

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

2.2 Mounting

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 is 300 ft. (91 m).

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 SPECIFIED LIMIT,AND DECREASE DISPLAY VISIBILITY.

Figure 2-1 or 2-2 illustrates the analyzer enclosure dimen-sions and panel mounting details. Using the two suppliedbrackets, attach them to the analyzer case as shown topanel mount the analyzer.

3.1 GLI ContactingConductivity Sensor(s)

Figure 2-3 or 2-4 on the next page shows the terminal ar-rangement and designations on the back of the analyzer.

NOTE: For easier wiring, terminal blocks can be unpluggedfrom their mating connectors. All terminals are suit-able for single wires up to 14 AWG (2.5 mm2).

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

1. Keep all cable shields as short as possible and con-nect them to earth ground.

2. Use Steward ferrite 28 B0590-000 or equivalent on:

Mains (line power) cable -- no turns required. Sensor cable -- one turn required. mA analog output cables -- two turns required. Relay cables -- no turns required.

3. In harsh conducted RF conditions, connect the earthground of the analyzer (Terminal 4 on TB1) to a local,known earth ground source.

All GLI Model 3400-series contacting conductivity sensorshave a built-in Pt 1000 ohm RTD temperature element forautomatic temp. compensation 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.

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.

The analyzer can be used with one or two conductivity sen-sors. Refer to Figure 2-5 and connect the wires of eachsensor (or interconnect) cable to appropriate terminals onTB3, matching colors as indicated.

NOTE: For best immunity to electromagnetic interference,always connect each sensor cable’s outer shieldwire (clear with black band -- not its clear-only innershield wire) to a terminal on TB2.

FIGURE 2-5 Connecting GLI Contacting Conductivity Sensor(s)



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:





• *Calculated Sensor A and B measurement (% reject, %pass, ratio A/B, ratio B/A, diff. A-B, or diff. B-A).

*An analog output can only represent the calculated measurement whentwo sensors are used and the analyzer has been correctly configured forCALCULATION.

The outputs are isolated from the inputs and earthground, but not from each other. For output configurationdetails, see PART THREE, Section 3.5.

Wiring Tip! Use high quality, shielded instrumentationcable for connecting the analog outputs.

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

• Output 1: Connect the load to Terminals 4 and 5 on TB4,matching polarity as indicated.

• Output 2: Connect the load to Terminals 6 and 7 on TB4,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 7for more HART communication information.



3.3 Relay Outputs The analyzer is equipped with two electromechanical re-lays. For relay setup details, see PART THREE, Section3.6.

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 CURRENT DRAWOF THE SWITCHED LOAD(S).

Two sets of SPDT relay outputs (Relays A and B) are pro-vided at Terminals 8 through 13 on TB4. The relay outputsare not powered. The line power used to power the ana-lyzer may also be used to power control/alarm devices withthese relay contacts. Refer to Figure 2-6 for a general wir-ing arrangement. Always check control wiring to insure thatline power will not be shorted by the relay switching action,and that wiring conforms to local codes.

WARNING:

MAKE SURE LINE POWER IS NOT PRESENT WHILECONNECTING WIRES TO TB4 RELAY TERMINALS.

FIGURE 2-6Connecting Control/Alarm Device(s) to Electromechanical Relay(s)



3.4 Line Power

Refer to Figure 2-7, 2-8 or 2-9 and connect line power toappropriate terminals on TB1 using the standard three-wireconnection arrangement. Use wiring practices which con-form to local codes (example: National Electric CodeHandbook in the U.S.A.).

WARNING:

REMOVE LINE POWER WHILE CONNECTING LINEPOWER WIRES TO THE TB1 TERMINALS. ALSO, USEONLY THE STANDARD THREE-WIRE CONNECTIONARRANGEMENT FOR SINGLE-PHASE LINE POWERTO PREVENT AN UNSAFE CONDITION, AND TOENSURE PROPER ANALYZER OPERATION.

NOTE: In all cases, connect the line power cable groundwire (usually green) to the “ground symbol” terminalon TB1.

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.

1.1 Display

1.2 Relay A and BIndicators

1.3 Keypad

The user interface consists of a two-line LCD display and akeypad with MENU, ENTER, ESC, ÕÕ, ÖÖ, ××, and ØØ keys.

The backlit, high resolution display is factory-set for opti-mum viewing contrast under all lighting conditions. By usingthe keypad, you can display three types of screens:

• MEASURE Screens: The normal display mode showsmeasured values. Pressing the ÕÕ or ÖÖ key sequentiallyscrolls through:

Sensor A value (conductivity, resistivity or TDS) Sensor A temperature Sensor B value (conductivity, resistivity or TDS) Sensor B temperature Analog Output 1 and Output 2 mA values Sensor A and B values and temperatures Calculated Sensor A and B measurement (% reject, % pass,

ratio A/B, ratio B/A, difference A-B, or difference B-A).

• 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.

Relay A and B red LED indicators light when their respec-tive relay energizes. (When a relay overfeed timer has“timed out,” the respective LED continuously blinks until theoverfeed condition is resolved.)

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

1. MENU key: Pressing this key with the MEASUREscreen displayed shows the “MAIN MENU CALIBRATE”screen. To display the CONFIGURE or TEST/MAINT

USER INTERFACE



top-level main branch screen, press the ØØ key. Press-ing MENU key with a menu screen displayed alwaysshows the top-level screen in that branch. (PressingMENU key also “aborts” the procedure to change val-ues or selections.)

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

3. ESC key: Pressing this key always takes the display upone level in the menu tree. (Example: With any “MAINMENU” screen displayed, pressing the ESC key oncetakes the display up one level to the MEASUREscreen.) This key can also “abort” the procedure tochange a value or selection.

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

• MEASURE Screen: Changes readout (in continuousloop sequence) to show different measurements.

• Menu Screens: These keys are non-functional.

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

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

• MEASURE Screen: These keys are non-functional.

• Menu Screens: Moves up or down respectivelybetween other same-level menu screens.

• Edit/Selection Screens: “Fine” adjusts the displayednumerical value (holding key down changes valuefaster), or moves up or down between choices.

FIGURE 3-1 Analyzer Keypad



1.4 MEASURE Screen(normal display mode)

The MEASURE screen is normally displayed. Pressing theMENU key temporarily replaces the MEASURE screen withthe top-level “MAIN MENU CALIBRATE” branch selectionscreen. Using the keypad, you can then display otherscreens to calibrate, configure or test the analyzer. If thekeypad is not used within 30 minutes, except duringcalibration or while using specific analyzer test/main-tenance functions, the display will automatically returnto the MEASURE screen. To display the MEASURE screenat any time, press the MENU key once and then the ESCkey once.

The MEASURE screen can show seven different readoutversions. To select between them, in continuous loopsequence, press the ÕÕ or ÖÖ key. These are examples ofthe different versions:

NOTE: When the analyzer returns to its normal MEASUREscreen mode, the appearing readout is always theversion last selected.

Note that the first four MEASURE screen examplesshow “SENSOR A” and “SENSOR B” notations ontheir top lines, illustrating the analyzer notation fea-ture. To create your own notation, refer to PARTTHREE, Section 3.2, subheading “ENTER NOTE(top line of MEASURE screen).”

The “CALC: % REJECT” example screen shows acalculated Sensor A and B measurement. Theanalyzer can also calculate and display othermeasurements. See PART THREE, Section 3.3 fordetails.

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

PART THREE - OPERATION SECTION 2 - MENU STRUCTURE


SECTION 2

2.1 DisplayingMain BranchSelection Screens

The analyzer menu tree is divided into three main branches:CALIBRATE, CONFIGURE, and TEST/MAINT. Each mainbranch is structured similarly in layers with top-levelscreens, related lower-level submenu screens and, in manycases, sub-submenu screens.

Each layer contains an EXIT screen to return the display upone level to the previous layer of screens.

Menu Structure Tip! For operating convenience, thelayers within each main branch are organized with themost frequently used function screens at their beginning,rather than the function screens used for initial startup.

1. With the MEASURE screen displayed, pressing the

MENU key always shows the branch selection screen. (Pressing the MENU key withany other type of screen displayed always returns thedisplay to the top of that respective menu branch.)

2. Press ØØ and ×× keys to select between the threemain branch selection screens (CALIBRATE,CONFIGURE or TEST/MAINT), or the EXIT screen:

3. With the desired MAIN MENU branch selection screendisplayed, press ENTER key to display the first top-level menu screen within that branch.

* Only select OPTIONAL TABLE choice when the analyzer isequipped with a customer-specified, factory-configured tem-perature compensation table, or you intend to configure aspecial table using the optional GLI software tool kit1000G3311 and an IBM-compatible PC.

NOTE: LINEAR is the factory default for temperaturecompensation with a 2.00% per °C slope and25.0°C reference temperature. This providesthe best results for most aqueous solutions. Toenter different slope and reference temperaturevalues for an uncommon solution, refer tosubheading “CONFIG LINEAR TemperatureCompensation” in this section for details.

Only when TDS is selected must the analyzer be furtherconfigured to define a conductivity-to-TDS conversionfactor. If CONDUCTIVITY or RESISTIVITY was selected,disregard this subsection -- no measurement configurationis needed.

Only when LINEAR is the selected temperature com-pensation, determine if the analyzer should be furtherconfigured with a specific slope (% per °C) and refer-ence temperature. If the built-in AMMONIA or NATURALWATER properties table or NONE was selected, disregardthis subsection -- no compensation configuration is needed.

NOTE: If “OPTIONAL TABLE” compensation was selected,the analyzer must be equipped with a customer-specified, factory-configured temperature compen-sation table, or you must configure a table using theoptional GLI software tool kit 1000G3311 and anIBM-compatible PC.



SELECT CELL K(sensor’s GLI-certified

“K” value)

Factory defaults for LINEAR compensation are 2.00%/°Cslope and 25.0° reference temperature. These values areappropriate for most aqueous solutions. Use chemicalhandbook tables to find values for uncommon solutions. Toenter different values:

1. With the or

ESC key once to return to the screen.

Each GLI Model 3400-series contacting conductivity sensorhas a unique, certified “K” value shown on a label attachedto its cable (or to the inside cover of its optional junction boxhead). By entering this “K” value, calibration (including ze-roing) is only necessary when this sensor is replaced. Thisalso sets the analyzer measuring range to match the inher-ent range of the sensor’s cell constant.



SET FILTER Time

1. With the (or )screen displayed, press ØØ key until

screen appears.



. Use ØØ and ×× keys to select thenominal cell category that corresponds to the sensor’sGLI-certified “K” value, and press ENTER key to enterit.

ESC key once to return to the screen.

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.





SelectPULSE SUPPRESS

(on/off)

ENTER NOTE (top lineof MEASURE screen)


. Use arrow keys to adjust to adesired filter time, and press ENTER key to enter it.

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 µS/cm, then suddenly jumps to 1950 µS/cm for a fewseconds, and returns to 1880 µS/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.




. Use ØØ and ×× keys to select thepulse suppress mode (OFF or ON), and press ENTERkey to enter it.

The top line of the MEASURE screen readouts that sepa-rately show the measurement are factory set to read “CONDA” and “COND B.” These notations can be changed, for ex-ample, to “BASIN 1” and “BASIN 2” to tailor the analyzerMEASURE screen to the application. The respective toplines would then be “MEASURE BASIN 1” and “MEASUREBASIN 2.” The notation is limited to eight characters whichcan be a combination of capital letters A through Z, num-bers 0 through 9, and spaces.

B. Press ÖÖ key once to select the next character, anduse ×× and ØØ keys to select its desired character.

C. Repeat this procedure until the desired notation isdisplayed.

3. Press ENTER key to enter the displayed notation.

Configure the analyzer for either automatic temperaturecompensation (by defining the sensor’s built-in Pt 1000 ohmRTD or an external Pt 100 ohm RTD), or fixed MANUALtemperature compensation. When using MANUAL you mustdetermine and enter a specific temperature.

NOTE: When a temperature element type has been se-lected but the element is not connected to theanalyzer, a “WARNING: CHECK STATUS” mes-sage will appear. To prevent or clear the message,connect the element or select “MANUAL.” Also,when using only one sensor, make sure that theunused sensor is set for “MANUAL.”

• PT1000: Selects automatic temperature compensa-tion using only a Pt 1000 RTD temperature element(used in all GLI Model 3400-series contacting con-ductivity sensors).

• PT100: Selects automatic temperature compensa-tion using only a Pt 100 RTD temperature element.

• MANUAL: Selects fixed manual temperaturecompensation (disregards temperature element --see step 4).

4. If “MANUAL” was selected, you must set the specificmanual temperature compensation value:

A. With the screen displayed,

press ØØ key once to display .

B. Press ENTER key to display a screen like

. Use arrow keys to adjust toa desired temperature for fixed MANUAL compen-sation, and press ENTER key to enter it.

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.

By entering the sensor’s unique T FACTOR, the analyzerwill provide the highest possible measuring accuracy forboth temperature and conductivity.





3.3 ConfiguringCALCULATION SensorA and B Measurement


. Use arrow keys to adjust thedisplayed value to exactly match the sensor’s GLI-certified T FACTOR, and press ENTER key to enter it.

SPECIAL CASE -- ALTERED SENSOR CABLE LENGTH(only for sensors with Pt 1000 temperature element*)

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°Cand the analyzer reads 53°C due to interconnect cable resis-tance. Multiply the 3°C difference by 3.85 ohms to get 11.55.Then increase the sensor T FACTOR by adding 11.55 to it andentering that value. If, due to a shortened sensor cable, theanalyzer was reading 3°C less than the known solution tem-perature you would decrease the sensor T FACTOR bysubtracting 11.55 from it.

*Sensors with a Pt100 temperature element provide inherently lessaccurate temperature readings and are not recommended.

case, the screen appears.


. Use ØØ and ×× keys to select thedisplayed temperature units (°C or °F), and pressENTER key to enter 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, both analog outputs can beheld at their last measured values:

• For up to 30 minutes by selecting the“HOLD OUTPUTS” function in the TEST/MAINT menuand pressing the ENTER key.

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

The output state selected during calibration (HOLD, XFERor ACTIVE) always takes precedence over an appliedTIMER relay hold. From the moment output hold is initiated(during calibration or from TEST/MAINT menu), the elapsedtime INTERVAL or DURATION countdown for a TIMER re-lay is temporarily suspended. Also, any TIMER relaycounting down DURATION time is turned off. When outputhold is released, 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.

NOTE: When using the HART communication option, a



SET PARAMETER(representation)

digital signal is encoded onto the 4-20 mA analogOutput 1 signal. In a HART SINGLE MODE wiringconfiguration, Output 1 remains available for normaluse. However, in a HART MULTI-DROP wiring con-figuration, Output 1 becomes dedicated to thatfunction and cannot be used. See PART THREE,Section 7 for more HART communication information.

These instructions configure Output 1. (Configure Output2 in the same way using its respective menu screens.)

Each output can be assigned to represent one of thesemeasurements (available choices determined by number ofsensors being used):

• Measured Sensor A value (conductivity, resistivity or TDS)• Measured Sensor A temperature• Measured Sensor B value (conductivity, resistivity or TDS)• Measured Sensor B temperature• *Calculated Sensor A and B measurement (% reject,

% pass, ratio A/B, ratio B/A, diff. A-B or diff. B-A)

*An analog output can only represent the calculated measurement whentwo sensors are used and the analyzer has been correctly configuredfor CALCULATION.


×× key -- not ØØ key -- until appears.



. Use ØØ and ×× keys to select theparameter the output will represent, and press ENTERkey to enter it.



SET 0/4 mA and20 mA VALUES(range expand)

SET TRANSFERValue (mA)

Parameter (or calculated measurement) values can be setto define the endpoints at which the 0/4 mA and 20 mAanalog output values are desired.




. Use arrow keys to set the valueat which 0/4 mA is desired, and press ENTER key toenter it.




. Use arrow keys to set the valueat which 20 mA is desired, and press ENTER key toenter it.

NOTE: If the same values are set for 0/4 mA and 20 mA, theoutput automatically goes to, and remains at, 20 mA.

Each analog output is normally active, responding to themeasured value of its assigned parameter. However, duringcalibration, you can transfer (XFER) each output to a presetvalue to operate a control element by an amount corre-sponding to that value. To set a mA transfer value for ananalog output to suit your application:




. Use arrow keys to set the de-sired mA transfer value, and press ENTER key to enterit.



SET FILTER Time

Select SCALE 0 mA/4 mA (low endpoint)

3.6 Configuring Relays(A and B)

A time constant (in seconds) can be set to filter or “smoothout” the output signal. A minimum value of “0 seconds” hasno smoothing effect. A maximum value of “60 seconds” pro-vides maximum smoothing. Deciding what output filter timeto use is a compromise. The higher the filter time, the longerthe output signal response time will be to a change in themeasured value.




. Use arrow keys to adjust to adesired filter time, and press ENTER key to enter it.

Each output can be set to be 0-20 mA or 4-20 mA.




. Use ØØ and ×× keys to select theminimum value for the analog output (0mA or 4mA), andpress ENTER key to enter it.

The analyzer is equipped with two electromechanical relays(A and B). Each relay can be set to function as aCONTROL, ALARM, TIMER or STATUS relay. For detailson each relay function, see subsection “SET FUNCTIONMode.”

During calibration, CONTROL and ALARM relays can beheld, transferred to preset on/off states, or remain active.During normal measurement operation, CONTROL andALARM relays can be held in their present on/off states for



SET PARAMETER(representation)

up to 30 minutes by selecting the “HOLD OUTPUTS” func-tion in the TEST/MAINT menu and pressing ENTER key.

NOTE: TIMER relays operate differently than CONTROL orALARM relays, and are affected differently. See theTIMER relay description in the “SET FUNCTIONMode” subsection for details.

These instructions configure Relay A. (Configure Relay Bin the same way using its respective menu screens.)

CONTROL or ALARM relay can be assigned to be driven byone of these measurements (available choices determinedby number of sensors being used):

• Measured Sensor A value (conductivity, resistivity or TDS)• Measured Sensor A temperature• Measured Sensor B value (conductivity, resistivity or TDS)• Measured Sensor B temperature• *Calculated Sensor A and B measurement (% reject,

% pass, ratio A/B, ratio B/A, diff. A-B or diff. B-A)

*A relay can only use the calculated measurement for its operationwhen two sensors are used and the analyzer has been correctly con-figured for CALCULATION.

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

. Use ØØ and ×× keys to select theparameter that will operate the relay, and press ENTERkey to enter it.



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

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 a sensor or analyzer “FAIL” diagnostic conditionis detected (see PART THREE, Section 5.1 for details).

• 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 down DUR-ATION time, both analog outputs and all ALARMand CONTROL relays are automatically “held”to ensure that connected devices are not dis-rupted by any upset condition the TIMER relayoperation may cause. An OFF DELAY time (1-999 seconds) can be entered to define howlong after the TIMER relay turns off that theoutputs and relays will remain held, providingtime for any upset condition to stabilize.

From the moment output hold is initiated (during cali-bration or from TEST/MAINT menu), the elapsed timeINTERVAL or DURATION countdown for a TIMER relayis temporarily suspended. Also, any TIMER relaycounting down DURATION time is turned off. Whenoutput hold is released, a TIMER relay resumes itsINTERVAL or DURATION countdown from the sus-pended time. When a TIMER relay is counting downDURATION time, both analog outputs are temporarilyheld until after the preset DURATION time (and OFFDELAY time, if used) elapses.





SET TRANSFERMode (relay on or off)

ACTIVATION(configuration values)


. Use ØØ and ×× keys to select thefunction for relay operation (ALARM, CONTROL,STATUS or TIMER), and press ENTER key to enter it.

Normally, each CONTROL or ALARM relay is active, re-sponding to the measured value of its assigned parameter.During calibration, however, you can transfer (XFER) eachrelay to a preset on/off state to suit your application re-quirements:




. Use ØØ and ×× keys to select thedesired relay transfer mode (DE-ENERGIZED orENERGIZED), and press ENTER key to enter it.

The group of configuration settings available to a relay isdependent on its selected function mode (ALARM,CONTROL or TIMER). Relays set for STATUS functionare not configurable. TABLE B describes all relay configu-ration settings, categorized by relay function mode:

TABLE B -- 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.

(TABLE B continued on next page.)



TABLE B -- Relay Configuration Settings -- (continued)

Setting Description

For ALARM Relay -- (continued)

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 6.

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 relays, may be beneficial in eliminat-ing process “overshoot” when there are long process piperuns or delays in mixing.

To set relay configuration values (ACTIVATION):



2. Press ENTER key to display the first respective relayfunction “ACTIVATION” screen setting.

3. Use the same basic keypad operations described inprevious setup procedures to enter the desired valuefor the displayed relay activation setting.

4. Repeat this procedure for each relay activation setting.



3.7 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 “3 4 5 6.” It cannot be changed.

To enable or disable the passcode feature:





4. Press ENTER key to display . UseØØ and ×× keys to select the desired passcode mode(DISABLED or ENABLED), and press ENTER key toenter it.

PART THREE - OPERATION SECTION 4 - ANALYZER CALIBRATION


SECTION 4

4.1 Important Information

Each contacting conductivity sensor has a unique zero pointand span. Consequently, always zero the sensor whencalibrating it for the first time (Section 4.2). Zeroing pro-vides the best possible measuring accuracy and, whenusing two sensors, eliminates any discrepancies betweenSensor A and B measurement channels. After zeroing, cali-brate for sensor span using GLI’s recommended DRY-CALmethod (Section 4.3). If desired, you can perform a tradi-tional wet calibration instead using the 1-POINT SAMPLEmethod (Section 4.4).

Calibration Tip! Conductivity measurement is greatlyaffected by small changes in temperature. To measuretemperature and conductivity more accurately, GLI highlyrecommends using the DRY-CAL method to calibrate forsensor span. (This is actually a normal part of configur-ing the sensor characteristics during initial startup.)DRY-CAL eliminates the need for conductivity refer-ence solutions. It also automatically sets the analyzermeasuring range to match the inherent range of the sen-sor’s cell constant. Furthermore, DRY-CAL eliminatesthe need to periodically re-calibrate! The only re-quirement, depending on the application, may beperiodic cleaning of the sensor. Only when the sensor isreplaced is a new DRY-CAL calibration necessary.

The analyzer analog output (1 and 2) mA values can alsobe calibrated. Refer to Section 4.5 for details.

These instructions calibrate Sensor A. (If using a secondsensor, calibrate Sensor B in the same way using its re-spective menu screens.)

NOTE: When the passcode feature is enabled (Section3.7), you must successfully enter the passcodebefore attempting to calibrate the analyzer.

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

• Press ENTER key to abort. After the “CONFIRMACTIVE?” screen appears, press ENTER key

ANALYZER CALIBRATION



4.2 ZERO Procedure(first-time sensorcalibration only)

to return the analog outputs and relays to theiractive states (MEASURE screen appears).

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

Zeroing/Calibration Tip! If a “CONFIRM FAILURE?”screen appears during zeroing or calibration, pressENTER key to confirm. Then, use the ×× or ØØ key toselect between “CAL: EXIT?” or “CAL: REPEAT?” and doone of the following:

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

• With “(CAL: REPEAT)” selected, press ENTER key torepeat 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 4.3 or Section 4.4).

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




4. Press ENTER key again to display .


6. Press ENTER key to display . Use×× and ØØ keys to select the status for analog outputs(and relays) during zeroing, and press ENTER key toenter it:

• HOLD OUTPUTS: Holds their present values.



4.3 DRY-CAL Method(highly recommended)

SELECT CELL K(sensor’s GLI-certified

“K” value)

• XFER OUTPUTS: Transfers to preset values.• ACTIVE OUTPUTS: Responds to measured values.

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

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

9. 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.

Every GLI contacting conductivity sensor has two unique,GLI-certified values that must be entered to complete aDRY-CAL calibration:

• Sensor CELL K value shown on a label attached to itscable or to the inside cover of its optional junction box.

• Temperature T FACTOR shown on the same label.(Since the inherent ohm value of the Pt 1000 RTD tem-perature element built into each sensor varies slightly,GLI tests each sensor to provide its specific T FACTOR.)

If these two GLI-certified values were previously enteredduring initial setup (Section 3.2 under respective subhead-ings), DRY-CAL calibration is complete. If the certifiedvalues have not been entered, use the steps in the following“SELECT CELL K” and “SET T FACTOR” subsections.

1. Press MENU key to display a “MAIN MENU” screen,

and use ØØ or ×× key to display .




SET T FACTOR(sensor’s GLI-certified

“T” factor)





7. Press ENTER key again to display a cell category selec-

tion screen like . Use ×× and ØØkeys to select the nominal cell category that corre-sponds to the sensor’s GLI-certified “K” value (shownon label attached to sensor cable or to inside cover ofits optional junction box), and press ENTER key to en-ter it.



9. Press ENTER key to display a cell “K” value screen like

. Use arrow keys to adjust thedisplayed value to exactly match the sensor’s GLI-certified “K” value, and press ENTER key to enter it.

After entering the “K” value, complete DRY-CAL calibrationby entering the GLI-certified “T” factor:


ESC key once to display .






5. Press ENTER key to display a “T” factor value screen

like . Use arrow keys to adjust thedisplayed value to exactly match the sensor’s GLI-certified “T” factor, and press ENTER key to enter it.

SPECIAL CASE -- ALTERED SENSOR CABLE LENGTH(only for sensors with Pt 1000 temperature element*)

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 temperaturereading to match the known solution temperature, decreasethe 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.

*Sensors with a Pt 100 temperature element provide inherently lessaccurate temperature readings and are not recommended.

6. After the screen re-appears, pressMENU key once and then ESC key once to display theMEASURE screen.

This completes GLI’s DRY-CAL calibration.



4.4 1 POINT SAMPLEMethod(wet calibration)

This “wet” calibration method requires you to immerse thesensor into a properly prepared conductivity reference solu-tion of known value, or to keep the sensor installed in theprocess while obtaining a process sample. When keepingthe sensor installed, determine the process value by labo-ratory analysis or comparison reading. In either case, enterthe known reference solution or sample conductivity 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 acomparison reading.

When Immersing Sensor in Reference Solution:

A. Prepare a conductivity reference solution usingyour normal method. Its value should be nearthe typical measured process value for best ac-curacy.

SECTION 6

6.1 Why Use anOverfeed Timer

6.2 Configuring RelayOverfeed Timers

6.3 Overfeed Timer“Timeout” Operation

6.4 Resetting OverfeedTimers

6.5 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 LED indicator will blink. This indicates that the relayis now off and will remain off until you manually reset theoverfeed timer. After reset, the relay LED stops blinking.(Both overfeed timers are reset simultaneously.)

To manually reset both relay overfeed timers, please referto PART THREE, Section 5.3.

A relay overfeed timer can, and often will, interact with otheranalyzer functions while those functions are in use. TABLEE on the next page explains common overfeed timer inter-actions.

PART THREE - OPERATION SECTION 7 - HART OPTION


SECTION 7

7.1 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 theanalyzer 4-20 mA analog Output 1 signal anywhere alongthe circuit wiring. See Sections 7.3 or 7.4 for more details.

HART OPTION



7.2 Analyzer OperatingModes forHART Network

HART enables simultaneous analog and digital communi-cation. The analyzer can be operated in a SINGLE MODEor MULTI-DROP mode on the 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,only when 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



7.3 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 (up) position for SINGLE MODE• MD (down) 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 Connections (for single analyzer)



7.4 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 (down) 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.

1.1 Inspecting SensorCable(s)

1.2 Replacing Fuse(s)

If a measurement problem exists and you suspect the sen-sor cables, inspect them for physical damage. If aninterconnect cable is used, check the junction box, then dis-connect the cable at both ends (junction box and analyzer)and, using an ohmmeter, check its wires for continuity andinternal shorts.

The analyzer is equipped with two internal, board-mountedfuses (80 and 100 mA; type T slow-blow; 5 mm x 20 mm).The fuses protect the 115 and 230 volt line power circuits.

WARNING:

DISCONNECT LINE POWER TO AVOID THEPOSSIBILITY OF ELECTRICAL SHOCK.

For Analyzers with Letter “A” Prefix Serial Number

1. After disconnecting line power, unplug all terminal con-nectors from their terminal strips.

1.3 Replacing Relays

3. Slowly pull the analyzer (front panel and all connectedcircuit boards) out of the case.

4. Locate the board-mounted fuses on the left circuitboard. Remove the blown fuse and replace it with a GLIfuse (or equivalent). A GLI fuse kit (part number1000G3315-102) for analyzers with letter “A” prefix se-rial number includes 80 mA and 100 mA fuses,replacement bezel, and new panel gasket.

5. Re-assemble the analyzer. Then plug all terminal con-nectors back into their terminal strips.

For Analyzers with “No Letter” Prefix Serial Number

1. After disconnecting line power, unplug all terminal con-nectors from their terminal strips.

2. Remove the four screws attaching the back panel, andremove the panel from the case.

3. Locate the board-mounted fuses on the left circuitboard. Remove the blown fuse and replace it with a GLIfuse (or equivalent). A GLI fuse kit (part number1000G3315-101) for analyzers with “no letter” prefix se-rial number includes 80 mA and 100 mA fuses.

4. Re-assemble the analyzer. Then plug all terminal con-nectors back into their terminal strips.

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 returnthe complete analyzer to GLI Customer Service or yourlocal factory-authorized service organization for relay re-placement.

2.1 Keeping Sensor(s)Clean

2.2 Keeping AnalyzerCalibrated

2.3 Avoiding ElectricalInterference

To maintain measurement accuracy, periodically clean thesensor(s). Operating experience will help you determinewhen to clean the sensor (daily, weekly, monthly, etc. inter-vals). Use the recommended cleaning procedure describedin the GLI contacting conductivity sensor operating manual.

If the DRY-CAL method (PART THREE, Section 4.3) wasused to calibrate sensor span, re-calibration is only neededwhen the sensor is replaced. If sensor span was cali-brated using the 1 POINT SAMPLE method, you mustperiodically re-calibrate. In either case, always calibratewhen replacing a sensor.

NOTE: If your measuring application requires utmost accu-racy, GLI offers a re-certification service to verify aused sensor’s “K” value and temperature “T” factor.For details, call your local GLI representative or GLICustomer Service.

Recommendation: Do not run sensor or interconnect ca-bles in the same conduit with AC or DC power wiring. Also,connect cable shielding as recommended (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).

3.1 Ground Loops

Determining ifGround Loop Exists

The analyzer may be affected by a “ground loop” problem(two or more electrically grounded points at different poten-tials).

Symptoms Indicating a Possible Ground Loop

• Analyzer reading is offset from the actual value by aconsistent amount, or ....

• Analyzer reading is frozen on one value, or .... • Analyzer reading is “off scale” (upscale or downscale).

Although the source of a ground loop is difficult to deter-mine, there are several common causes.

Common Causes of a Ground Loop

• Components, such as recorders or computers, areconnected to non-isolated analog outputs.

• Not using shielded cabling or failure to properly connect

all cable shields. • Moisture or corrosion in a junction box. The following simple test can help to determine if there is aground loop:

1. With the conductivity MEASURE screen displayed, im-merse the sensor in a non-conductive container (plasticor glass) filled with solution of a known conductivityvalue. Note the analyzer reading for this solution.

2. Connect one end of a wire to a known earth ground

such as the analyzer ground terminal on TB1 or a metalwater pipe. Place the other end of this wire into the ref-erence solution next to the sensor.

3. Note the analyzer reading now and compare it with the

reading taken in step 1. If the reading changed, aground loop exists.

CheckingElectrical Connections

VerifyingSensor Operation

VerifyingAnalyzer Operation

Sometimes the source of a ground loop is easy to find, but itusually takes an organized approach to isolate the problem.

Troubleshooting Tip! Use a systematic troubleshootingmethod. If possible, start by grounding all shields andelectrical grounds at one stable point. One at a time, turnoff all pumps, motors and switches that are in contactwith the process. Each time you do this, check if theground loop still exists. Since the process media beingmeasured is electrically conductive, the source of theground loop may not be readily apparent.

When experiencing problems, try to determine the primarymeasurement system component causing the problem (sen-sor, analyzer or interconnect cable, if used).

1. Verify that line power exists at the appropriate analyzerTB1 terminals.

2. Check all analyzer cable connections to ensure they

are properly connected.

To verify sensor operation, refer to the procedure in thetroubleshooting section of the sensor operating manual. Orreplace the suspect sensor with a known new or workingsensor and perform calibration.

This procedure verifies the operation of the Sensor Ameasuring channel. (Verify the Sensor B channel in thesame way using its respective terminal connections.

WARNING:




1. After disconnecting line power and the sensor from theanalyzer, connect a 1% tolerance, 1097 ohm resistorbetween Terminals 4 (white) and 5 (blue) on TB3.(When configured for a PT100 temperature element,use a 1% tolerance, 110 ohm resistor.)

2. Depending on the configured sensor cell constant,measuring units, and range, use the listed resistance inTABLE F (1% tolerance resistor or decade box) andconnect it between Terminals 1 (red) and 2 (black) onTB3.

3. Reconnect line power to the analyzer.

WARNING:

LINE POWER IS PRESENT. BE CAREFUL TOAVOID ELECTRICAL SHOCK.

4. Verify that the analyzer conductivity reading is full-scalefor the applicable range. Also, verify that the analyzertemperature reading is 0°C.

If these readings are achieved, the analyzer is operatingproperly, but the interconnect cable (if used) may be faulty.



Verifying InterconnectCable Integrity

WARNING:


1. Disconnect line power and the resistors or decade boxfrom the analyzer.

2. Reconnect the sensor directly to the analyzer (pur-posely bypassing the interconnect cable and junctionbox).

3. Place the sensor in a container of known value conduc-tivity reference solution that is at room temperature(approximately 25°C).

4. Reconnect line power to the analyzer.

WARNING:

LINE POWER IS PRESENT. BE CAREFUL TOAVOID ELECTRICAL SHOCK.

5. Verify that the analyzer reading is the same as theknown reference solution value. If the reading isachieved, the interconnect cable and/or junction boxconnections are probably faulty. Use a digital multime-ter to check the interconnect cable for shorted or openwires.
