DESCRIPTION AND SPECIFICATIONS

1.1 FEATURES AND APPLICATIONS

The Model 1054B Microprocessor Analyzers, with the appropriate sensors, are designed to continuously measure and control pH, ORP, conductivity, resistivity, ratio, percent concentration, dissolved oxygen, ozone or total free chlorine in industrial and municipal processes.

The Model 1054B Conductivity Analyzers are housed in a NEMA 4X (IP65) weatherproof, corrosion-resistant, flame retardant enclosure suitable for panel, pipe or wall mounting. All functions are accessed through the front panel membrane keyboard which features tactile feedback. Measurement data may be read at any time. However, settings may be protected against accidental or unauthorized changes by a user selectable security code. The display indicates the measured value in engineering units as well as temperature, alarm status, hold output and fault conditions.

The 1054B transmits a user selected isolated current output which is continuously expandable over the measurement range for either direct or reverse action and can be displayed in milliamps or percent. Output dampening of 0-255 sec. is user selectable.

The output and relay default settings are user selectable for hold or fault mode operation. The hold output function allows manual control during routine sensor maintenance.

Continuous self diagnostics alert the operator to faults due to analyzer electronics, integral RTD failures, open wiring and process variable range problems. In the event of a fault condition or hold mode diagnosed by the analyzer, the output will be set to a preset or last process value and the relays will be set to their default settings.

Dual alarms are a standard feature on the Model 1054B and are programmable for either high or low operation. Alarm 2 may be programmed as a fault alarm. Both alarms feature independent setpoints, adjustable hysteresis and time delay action. The time delay is convenient when an alarm is used for corrective action, such as shutting down a demineralizer for regeneration. Time delay will ignore a temporary breakthrough and prevent shutting down a demineralizer unit prematurely. A dedicated interval timer with relay is also provided.

Automatic or manual temperature compensation is keyboard selectable. The process temperature is accurately measured from an integral RTD in the sensor assembly and is read on the display. For greater accuracy, the temperature indication may be standardized to the process temperature. The temperature may be configured to read in °C or °F.

Calibration is easily accomplished by simply immersing the sensor in a known solution and entering the value. With a two point calibration, the Model 1054B will automatically calculate the temperature slope of the solution. Upon routine standardization a sensor cell factor value is calculated, and a trend of this value can be used to track sensor coating.

The Model 1054B Microprocessor Analyzer comes standard with an LCD display. An LED display is available as an option.

• SELF DIAGNOSTICS with a user selectable fault alarm.

• KEYBOARD SECURITY is user selectable.

• NO BATTERY BACK-UP REQUIRED. Non-volatile EEPROM memory.

• DUAL ALARMS WITH PROGRAMMABLE LOGIC. A third relay is provided with timer functions.

• PROGRAMMABLE OUTPUT AND RELAY DEFAULTS for hold and fault modes.

• NEMA 4X (IP65) WEATHERPROOF CORROSION-RESISTANT ENCLOSURE.

DESCRIPTION AND SPECIFICATIONS

The Model 1054B Conductivity Analyzer measures over the range of 0-2 µS/cm to 0-1,000 mS/cm. Temperature slope may be adjusted anywhere between 0 and 5% to provide greater accuracy in chemical concentration control. The temperature slope is factory set at 2% as a representative value, but each conductive solution has its own set of temperature vs. concentration curves. The Model 1054B C will automatically calculate the temperature slope for any given solution, or permit manual adjustment of the temperature slope if already known. On calibration the analyzer will also automatically correct for cell constant variations for better measurement accuracy.

INSTALLATION

2.1 GENERAL. Installation must be performed by a

trained technician. This analyzer's enclosure is suitable for outdoor use. However, it should be located in an area where temperature extremes and vibrations are minimized or absent. Installation must be performed by a trained technician.

2.2 UNPACKING AND INSPECTION. Inspect the

analyzer for shipping damage. If damaged, notify the carrier immediately. Confirm that all items shown on the packing list are present. Notify Rosemount Analytical if items are missing.

2.3 MECHANICAL INSTALLATION. Select an instal-

lation site that is at least one foot from any high voltage conduit, has easy access for operating personnel, and is not in direct sunlight. Mount the analyzer as follows:

1. Remove the four screws that secure the rear

cover of the enclosure.

2. Remove the four screws holding the front panel

assembly of the enclosure and carefully pull the front panel and connected printed circuit boards straight out.

3. Follow the procedure for the appropriate mounting

configuration: Section 2.3.1 for panel mounting, Section 2.3.2 for wall mounting, Section 2.3.3 for pipe mounting.

2.3.1 Panel Mounting (Standard). The Model 1054B

is designed to fit into a DIN standard 137.9 mm x

137.9 mm (5.43 in. x 5.43 in.) panel cutout (Refer to

Figure 2-1 and Figure 2-2).

1. Prepare the analyzer as described in Section 2.3.

2. Install the mounting latches as described in Figure

2-2 (latches are shown oversize for clarity). If the latches are not installed exactly as shown, they will not work correctly. The screws provided are self-tapping. Tap the screw the full depth of the mounting latch (refer to side view) leaving a gap greater than the thickness of the cutout panel.

3. Align the latches as shown and insert the analyzer enclosure through the front of the panel cutout. Tighten the screws for a firm fit. To avoid damaging the mounting latches, do not use excessive force.

4. Replace the front panel assembly. Circuit boards must align with the slots on the inside of the enclosure. Assure that the continuity wire is connected to the rear cover and the interface board’s closest mounting screw. Replace the door and four front panel screws.

2.3.2 Wall Mounting Plate with Junction Box

(P/N 23054-01). Refer to Figure 2-3 and Figure 2-4.

1. Prepare the analyzer as described in Section 2.3.

2. Mount the junction box and bracket to the analyzer with the hardware provided. All wiring can be brought to the terminal strip prior to mounting the analyzer.

3. Place the metal stiffener on the inside of the analyzer and mount the two 1/2-inch conduit fittings using two each weather seals as shown. Mount NEMA 4X conduit plug (included) into center conduit hole.

4. Mount the analyzer to the junction box using the 1/2-inch conduit fittings.

Figure 2-7 for installation details.

MODEL 1054B C SECTION 2.0

INSTALLATION

2.4 ELECTRICAL WIRING. The Model 1054B has

three conduit openings in the bottom rear of the analyzer housing which will accommodate 1/2-inch conduit fittings. From the front view, the conduit opening on the left is for sensor wiring; the center is for signal output and the opening on the right is for timer, alarm, and AC connections. Sensor wiring should always be run in a separate conduit from power wiring. AC power wiring should be 14 gauge or greater.

NOTE

For maximum EMI/RFI protection the output cable should be shielded and enclosed in an earth grounded, rigid metal conduit. When wiring directly to the instrument connect the output cable’s outer shield to the transmitter’s earth ground via terminal 8 on TB3. When wiring to the wall mounting junction box connect the output cable’s outer shield to the earth ground terminal on TB-A. The sensor cable should also be shielded. When wiring directly to the instrument connect the sensor cable’s outer shield to the transmitter’s earth ground via terminal 8 of TB-2. If the sensor cable’s outer shield is braided an appropriate metal cable gland fitting may be used to connect to braid to earth ground via the instrument case. When wiring to the wall mounting junction box connect the sensor cable’s outer shield to the earth ground terminal on TB-A. The user must provide a means to disconnect the main power supply in the form of circuit breaker or switch. The circuit breaker or the switch must be located in close proximity to the instrument and identified as the disconnecting device for the instrument.

2.4.1 Power Input Wiring. The Model 1054B can be configured for either 115 VAC or 230 VAC power.

Connect AC power to TB1-8 and -9 (115 VAC) or TB17 and -8 (230 VAC) ground to the ground terminal at TB3-8 (refer to Figure 2-6).

CAUTION

The sensitivity and stability of the analyzer will be impaired if the input wiring is not grounded. DO NOT apply power to the analyzer until all electrical connections are verified and secure. The following precautions are a guide using UL 508 as a safeguard for personnel and property.

1. AC connections and grounding must be in compliance with UL 508 and/or local electrical codes.

2. The metal stiffener is required to provide support and proper electrical continuity between conduit fittings.

3. This type 4/4X enclosure requires a conduit hub or equivalent that provides watertight connect, REF UL 508-26.10.

4. Watertight fittings/hubs that comply with the requirements of UL 514B are to be used.

5. Conduit hubs are to be connected to the conduit before the hub is connected to the enclosure, REF UL 508-26.10.

6. If the metal support plate is not used, plastic fittings must be used to prevent structural damage to the enclosure. Also, appropriate grounding lug and awg conductor must be used with the plastic fittings.

2.4.2 Output Wiring. The signal output and alarm

connections are made to terminals 1 through 6 of TB1 and TB3-1 and 2. (Refer to Figure 2-6).

SECTION 4.0

CONFIGURATION

4.1 GENERAL. This section details all of the items avail-

able in the Set Mode to configure the analyzer to a specific application.

4.1.1. Configuration Worksheet. The configuration worksheet on the following page should be filled out before proceeding with the analyzer’s configuration. This sheet gives a brief parameter description, the factory setting, and a space for user setting.

4.1.2 Set Mode Display Mnemonic SEt. Most of the analyzer's configuration is done while in the Set Mode. Please refer to Figure 3-5 for the layout of all menu items. All menu variables are written to the analyzer's EEPROM (memory) when selected and remain there until changed. As these variables remain in memory even after the analyzer's power is removed, the analyzer configuration may be performed prior to installing it.

1. Power up the analyzer. Only power input wiring is required for analyzer configuration (Refer to Section 2.4.1). The analyzer's display will begin showing values and/or fault mnemonics. All fault mnemonics will be suppressed while the analyzer is in Set Mode (the fault flag will continue to blink).

2. Enter Set Mode. Pressing the ACCESS key twice in rapid succession will place the analyzer in Set Mode. The display will show SEt to confirm that it is in Set Mode. It will then display the first item in the set menu. The analyzer is now ready for user configuration.

NOTE:

If LOC displays, the Keyboard Security Code must be entered to access the Set Mode. (Refer to Section 6.0.)

3. Analyzer variables can be entered in any order. On initial configuration, however, it is recommended that the variables be entered in the order shown on the worksheet. Refer to the configuration worksheet (Table 4-1). This will reduce the chance of accidentally omitting a needed variable.

START-UP AND CALIBRATION

SECTION 5.0

START-UP AND CALIBRATION

5.1 GENERAL. Calibration and operation of the Model

1054B should begin only after completion of the configuration of the analyzer. The sensor must be wired (including J-box and interconnecting cable) as it will be in operation.

NOTE READ THE ENTIRE CALIBRATION SECTION TO DETERMINE THE CALIBRATION PLAN MOST SUITABLE FOR YOUR NEEDS.

5.2 Entering the Cell Constant. The first time the

analyzer is calibrated and any time there is a sensor change, the sensor cell constant must be entered into memory. Entering a cell constant into memory will reset the cell factor Fct to 1.0 and will initiate the analyzer (the cell factor gives an indication of sensor scaling. Refer to Section 8.2.3).

1. Enter the Set Mode. Press the ACCESS key twice in rapid succession. The analyzer will display SEt briefly then display Cin.

2. SCROLL (

é ) the menu until CEL is displayed,

then SELECT it. The Numerical display will flash to indicate that a value is desired.

3. Use SCROLL (é) and SHIFT (ç) to display the correct sensor cell constant and ENTER it into memory. This value can be found on the cable label (i.e., Sensor K= 1.00).

NOTE

Only adjust the cell constant when the conductivity sensor is replaced or serviced. Then always perform a restandardization. See Section 5.5.

5.3 Temperature Calibration. For accurate tempera-

ture correction, the temperature reading may need adjusting. The following steps must be performed with the sensor in the process or in a grab sample. For the most accurate results, standardization should be performed at or near operating temperature.

1. Observe the analyzer temperature reading by pressing the TEMP key. Allow the reading to stabilize to insure that the sensor has acclimated to the process temperature.

2. Compare the analyzer reading to a calibrated temperature reading device. If the reading requires adjusting, proceed to Step 3, otherwise, go to Section 5.4.

3. Press the TEMP key then the SELECT key to correct the temperature display. The analyzer will display AdJ briefly, then the Numeric Display will show with digit flashing.

4. SCROLL (é ) and SHIFT (ç) to display the correct value and ENTER it into memory. Proceed to Section 5.4.

5.4 Initial Loop Calibration. Please read the entire

calibration section before proceeding to determine the best plan to follow.

A. Two Point Calibration - Standard Method. This is the recommended procedure for the initial calibration if the process's temperature slope is unknown. If any of the steps below are impossible or impractical, refer to the alternate Section 5.4 B.

1. Obtain a grab sample of the process to be measured.

2. Determine the sample's conductivity using a calibrated bench or portable analyzer. The analyzer must be able to reference the conductivity to 25°C, or the solution must be measured at 25°C. Note the reading. Insure that the analyzer is in hold. Press the HOLD key twice and observe the solid flag.

3. Immerse the analyzer's sensor into the process solution. The sensor body must be held away from the bottom and sides of the sample's container and the sensor cable must not be allowed to contact the solution. Shake the sensor to ensure that no air bubbles are present.

4. Adjust the sample's temperature to either the normal high or normal low temperature of the process. To raise the sample's temperature, a hot plate with stirrer is recommended. To lower the process temperature, place the grab sample's container in an ice bath or let it slowly cool down.

START-UP AND CALIBRATION

A. Two Point Calibration. (continued)

5. Allow the sensor to acclimate to the solution. (The temperature reading should be stable.)

6. Press the CAL key. 15t displays briefly (if 2nd displays, press CAL again), then the Numeric Adjustment window displays.

7. SCROLL (

é) and SHIFT (ç) to display the grab

sample's conductivity value at 25°C as noted in Step 2, then ENTER into memory.

8. Adjust the sample's temperature to the other normal temperature extreme of the process. To raise the sample's temperature, a hot plate with stirrer is recommended. To lower the process temperature, place the grab sample container in an ice bath.

9. Allow the sensor to acclimate to the solution. (The temperature reading should be stable.)

10. Press the CAL key. 15t displays briefly (If 2nd displays, press CAL again), then the Numeric Adjustment window displays.

11. SCROLL (é ) and SHIFT (ç) to display the grab sample's conductivity value 25°C as noted in Step 2, then ENTER into memory.

The analyzer will then calculate the true cell constant and the temperature slope then return to reading conductivity. The temperature slope of the process can now be read. Press the CAL key twice. The display will show SLP briefly then the calculated slope for the two calibration points. Place the sensor in the process, then remove the analyzer from hold by pressing the HOLD key twice again.

The slope may be calculated from the following formula:

B. Single Point Calibration - Slope Known. This is the recommended procedure for the initial calibration if the temperature slope of the process is known.

If you do not know the exact temperature slope value, but wish to approximate it, refer to the following guide. However, the conductivity reading may have reduced accuracy compared to the value if the procedure in Section A is performed.

Acids: 1.0 to 1.6% per °C Bases: 1.8 to 2.2% per °C Salts: 2.2 to 3.0% per °C Water: 2.0% per °C

1. Press the CAL key twice. The analyzer will display SLP briefly, then show the temperature slope in memory.

2. SELECT to change the value. The analyzer will display AdJ briefly, then show the Numeric Display window.

3. SCROLL (

é) and SHIFT (ç) to display the proper

temperature slope for the process to be measured, then ENTER into memory.

4. Obtain a grab sample of the process to be measured.

5. Determine the conductivity of the sample using a calibrated bench instrument or portable analyzer. The instrument must be able to reference the conductivity to 25°C or the solution must be measured at 25°C. Note the reading. Insure that the analyzer is in hold. Press the HOLD key twice and observe the solid flag.

6. Press the PV key once then press the SELECT key once. Std will display followed by the Numeric Display with digit flashing.

7. SCROLL (é ) and SHIFT (ç) to display the conductivity value you noted in Step 5, then ENTER it into memory.

8. Install the sensor in the process, then remove the analyzer from hold by pressing the HOLD key twice.

The analyzer will calculate the true cell constant after the initial calibration.

5.5 Routine Standardization. The sensor should be

standardized routinely if it is suspected that the process might degrade or coat the sensor. When a sensor cell constant is entered CEL is set to this value and the cell factor Fct is set to 1.000. The first standardization recalculates the cell constant CEL. Subsequent standardizations will change the cell factor Fct. Refer to Section 8.2.3 for a description of the cell factor.

To perform a standardization do the following:

1. Take a grab sample which is as close to the sensor as possible. Write down the value the analyzer is reading at this time (C1).

2. Measure the conductivity of the grab sample using a calibrated bench analyzer referenced to 25°C/77°F or measured at 25°C. Write down this value (C2).

3. Before entering the reference value, note the value the analyzer is reading now (C3) and compare it to the value in Step 1. This accounts for the change while the grab sample is being measured.

4. Press the PV key once, then press SELECT. Std will display briefly followed by the Numeric display with flashing digit.

5. The corrected conductivity reference value may be determined by multiplying the value in Step 2 (C2) by the value noted in Step 3 (C3) and dividing the product by the analyzer value from Step 1 (C1):

C2x C

= C

Enter this corrected reference value in the analyzer using the SCROLL (é ) and SHIFT (ç) keys. Then press ENTER.

6. Note the cell factor value Fct. Press the ACCESS key twice quickly. SCROLL (é ) to Fct press SELECT and note this value. Keep track of this value to determine a sensor cleaning schedule.

5.6 Sensor Maintenance. Before performing maintenance or cleaning of the sensor, the Model 1054B C should be placed in hold. This will place the current output and relays in the states determined in Section 4.6. Before removing the sensor from the process, press the HOLD key twice. The HOLD flag will show to indicate the hold condition.

Always reenter the cell constant (Section 5.2) and restandardize (Section 5.5) after cleaning or replacement of the sensor.

Replace the sensor back into the process and press the HOLD key twice again to remove the analyzer from hold. The hold flag will disappear.

THEORY OF OPERATION. This section is a general

description of how the analyzer operates. This section is for those users who desire a greater understanding of the analyzer’s operation.

A square wave measurement circuit in the Model 1054B C Analyzer replaces the typical bridge circuit used in most conductivity analyzers, resulting in improved linearity, accuracy and a broad measurement range. The analyzer measures the absolute conductivity of the measured process. The analyzer then corrects the conductivity to 25°C by accurately measuring the process temperature by means of a PT-100 RTD located in the conductivity sensor. The microprocessor also adjusts the amount of correction required for temperature compensation by means of a temperature slope adjustment.

The slope may be adjusted between 0-5%/°C either manually via the keyboard or automatically during bench or process calibration. This slope controls the amount of correction required in the temperature compensation circuit, and is specific to the process, giving you the most accurate conductivity reading possible.

The Model 1054B C analyzer can provide conductivity measurements as low as 1 uS/cm and as high as 1000 mS/cm full scale over a process temperature range of 0 to 200°C.

Rosemount Analytical also offers a booklet titled Conductance Data for Commonly Used Chemicals. This booklet includes measurement theory and conductance information for commonly used chemicals.

6.1 GENERAL. Display Mnemonic COd. Select this fea- ture to display the user defined security code. Any three digit number may be used for this code. 000 will disable the security feature. This item is used to prevent accidental changes to the calibration and configuration of the analyzer. When activated, the analyzer will allow all read functions to read normally. If an attempt is made to change a value, LOC will display followed by the Numeric Display ready for the code to be entered. A proper code will unlock the analyzer and the analyzer will return to the last function attempted. Any incorrect value will result in bAd briefly displaying. The analyzer will then return to numeric display and await the entry of the code. Once unlocked, the analyzer will allow access to all functions until the analyzer is either powered down or no keystrokes are made for a period of two (2) minutes. If the code should be forgotten, pressing and holding the ACCESS key for five (5) seconds will result in display of the code. Releasing the ACCESS key, then pressing ENTER will unlock the analyzer.

6.2 ACCESS CODE (COd).

1. Enter Set Mode by pressing ACCESS key twice.

2. SCROLL (

é) until COd appears on the display.

3. Press SELECT.

4. SCROLL (

é ) and SHIFT ( ç ) to display the

desired value, then ENTER it into memory.

NOTE

Entering 000 disables the keyboard security.

NOTE

Security feature will not activate until two (2) minutes without keyboard activity or power is removed from the analyzer then restored.

8.1 DIAGNOSTICS. The Model 1054B analyzer has a diagnostic feature which automatically searches for fault conditions that would cause an error in the measured conductivity value. If such a condition occurs, the current output and relays will act as configured in default and the fault flag and display will flash. A fault code mnemonic will display at frequent intervals. If more than one fault condition exists, the display will sequence the faults at one second intervals. This will continue until the cause of the fault has been corrected. Display of fault mnemonics is suppressed when in Set Mode. Selecting the SHO item will display a history of the two most recent fault conditions unless SHO was cleared (Refer to Section 4.6).

NOTE

If the analyzer is in hold and a fault occurs, the mnemonic HLd will display during the fault sequence.

8.1.1 Fault Mnemonics. Table 8-1 (below) lists the fault mnemonics and describes the meaning of each.

8.1.2 Temperature Compensation. Table 8-2 (below)

is a ready reference of RTD resistance values at various temperatures. These are used for test and evaluation of the sensor.

NOTE

Ohmic values are read across the T.C. element and are based on the stated values (R

± .12%). Allow enough time for the T.C. element to stabilize to the surrounding temperature. Each 1°C change corresponds to a change of

0.385 ohms.

DIAGNOSTICS AND TROUBLESHOOTING

8.2 TROUBLESHOOTING. The Model 1054B analyz-

er is designed with the state of the art microprocessor circuitry. This design incorporates programmed features that provide constant monitoring for fault conditions, and the reporting of these faults via Mnemonics on the instrument display screen. This aids in determining where to start checking for the cause of failures, and in some instances, the ability to see changes that can be used to predict future degeneration of assemblies before their complete failure.

8.2.1 Installation Failure. After completion of installation the instrument should be checked for operation. Normally this would consist of Powering up the instrument and checking for:

1. A self diagnostic fault display. Refer to Table 8-1 for brief description of problem indicated by mnemonic. Table 8-3 provides a more comprehensive problem explanation and actions that may help solve the problem.

2. A conductivity reading that is approximately correct (depending upon sensor installation in either air or process). Refer to Section 8.2.3 for sensor checks.

3. Pressing several of the keypads to determine whether programming appears to be operational. Table 8-3 explains problems and actions that may be helpful in solving them.

4. Checking output for 4-20 mA output current.

8.2.2 After Operation. Troubleshooting this instrument

after previous operation should follow normal troubleshooting procedures. Check display. If power is O.K. the display mnemonic will direct you to the basic area of malfunction (Sensor, Printed Circuit Boards, calibration, or temperature compensation).

Use Table 8-1 and Table 8-3 to determine area, possible problem and actions to take to remedy fault.

Evaluate instrument electronics. This can be accomplished by simulating a known conductivity input and observation of instrument operation. To simulate sensor operation with known conductivity inputs, use the following procedures.

1. Disconnect the Sensor input leads from TB2-1, 3, 6, and 7.

2. Install decade box or resistor leads to TB2-1 and 3. (If decade box is not available, simulate desired conductivity input by either calculating using the formula given in Figure 8-1, or by using the Conductivity vs. resistance Table in Figure 8-1.)

3. Install a jumper between TB2-6 and 7. Check wiring with Figure 8-1.

4. Power up instrument and enter SEt menu.

5. Turn Atc to oFF.

6. Set manual temperature compensation to 25°C (See Section 4.4 and Figure 4-4).

7. Set Cell constant to 1.0 (See Section 5.1.1).

8. Evaluate analyzer response with previous responses.

Faulty display. If a faulty display is suspected, enter the SET menu and scroll through to the dtS option. This option will activate all display segments. See Figure 3-4.

Output Circuit Testing. To check for problems in the output circuit, bypass the sensor input and analyzer calculations by setting a known output current and checking item driven by output current and checking the operation of valves, pumps, recorders, etc. For directions on how to set output current, refer to Section 4.9.

8.2.3 Sensor Troubleshooting. In addition to the sen-

sor fault mnemonics, the analyzer can display information pertinent to determining if sensor has become coated, or if there is a conductivity versus temperature problem, or an application problem.

Sensor Coated. As the cell becomes coated, or affected by the process, the cell factor will change. Tracking this change in cell factor will prevent use of a sensor that has lost its sensitivity because of contamination or damage.

CAUTION

Standardizing the instrument results in the cell factor being returned to 1.0.

This instrument tracks the change in calculated cell factor from the initial cell factor value of 1.0 every time the unit is standardized. The cell factor should be checked and tracked to set up a regular maintenance schedule and can be seen in the following manner:

1. Press ACCESS key twice.

2. SEt will be displayed briefly followed by Cin.

3. SCROLL (

é) to display Fct and press SELECT.

4. To return to normal operation, press PV.

DIAGNOSTICS AND TROUBLESHOOTING

Absolute Conductivity. As an aid in determining

whether a problem exists in the conductivity section of the sensor or analyzer, or the temperature compensating circuits, the absolute conductivity (the uncorrected conductivity value, without temperature compensation) of the process can be displayed. To do so:

1. Press ACCESS key twice.

2. SEt will be displayed briefly followed by Cin.

3. SELECT Cin to read the absolute conductivity.

4. To return to normal operation, press PV.

Temperature Sensor accuracy. If the temperature sensor in the conductivity sensor is suspect, measuring the resistance across the T.C. element and comparing the corresponding temperature reading can be used in the evaluation of the sensor. Allow enough time for the T.C. element to stabilize to the surrounding temperature. Each 1°C change corresponds to a change of 0.385 ohms.

8.2.4 Subassembly Replacement Considerations.

CPU Board Replacement. If a problem exists on the

CPU board, and replacement is required, specific procedures included with the new board must be followed or the microprocessor will be improperly programmed. Should this occur, it will be necessary to return the analyzer to the factory for reprogramming.

Power Board Replacement. If it becomes necessary to replace the power board, the CPU board will need to be recalibrated following the specific procedures that are included with the power board. Failure to follow these procedures exactly will cause the microprocessor to be improperly programmed and require the return of the analyzer to the factory for reprogramming.

8.2.5 Instrument Electronic Check. This procedure will allow the operation of the analyzer to be evaluated by simulating a known conductivity input.

1. Disconnect the conductivity sensor input leads from TB2-1, 3, 6 and 7. Install decade box or resistor leads to TB2-1 and 3 and a jumper to TB2-6 and 7 (see Figure 8-1).

2. With instrument power on, enter the SEt menu and turn Atc to oFF. Set manual temperature compensation to 25°C (see Section 4.4 and Figure 4-3).

3. Set cell constant to 1.0 (see Section 5.1.1).

4. To simulate a desired conductivity input, an appropriate resistance value may be calculated by Formula or selected from the conductivity (µmhos) vs resistance (ohms) table (see Figure 8-1).

5. Simulate conductivity input and evaluate the analyzer response.

8.3 INSTRUMENT MAINTENANCE. To maintain the

appearance and extend the life of the enclosure, it should be cleaned on a regular basis using a mild soap and water solution followed by a clean water rinse.
