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 Resistivity 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 secs. 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 de-mineralizer unit prematurely. A dedicated interval timer with relay is also provided.

Automatic neutral salt cation correction temperature compensation is standard. The process temperature is accurately measured by an integral RTD in the sensor assembly and is read on the display in °C. For greater accuracy, the temperature indication may be standardized to the process temperature.

Calibration is easily accomplished by entering the cell calibration constant (shown on the sensor tag) via the 1045B’s keypad. Standardization can also be made with the cell in process of known conductivity (resistivity).

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

• SPECIAL TEMPERATURE COMPENSATION for low conductivity (high resistivity) meas-

urement.

• 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 func-

tions.

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

MODEL 1054B LC SECTION 1.0

DESCRIPTION AND SPECIFICATIONS

The Model 1054B Low Conductivity Analyzer measures 0-20 µS/cm or 0-18.3 megohm/cm. It is commonly known that in measuring the resistivity or conductivity of ultrapure water, temperature compensation is very critical. The temperature coefficient of ultrapure water depends both on the temperature and resistivity/conductivity of the water being tested. The Model 1054BLC incorporates a 1000 ohm RTD for temperature measurement, and is capable of measuring and displaying temperature accurately within ± 0.1°C. Temperature measurement is resolved to 0.025°C and this precise measurement is used in the analyzer’s temperature compensation calculation. Temperature compensation formula appropriate for water contaminated with minute quantities of sodium chloride is user selectable. For Cation resin columns, a formula specific to the characteristics of pure water contaminated with minute quantities of hydrochloric acid is user selectable.

2.1 GENERAL. 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 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 installation 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 inch X 5.43 inch) 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.

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.

5. Complete wiring from the analyzer to the junction box (Refer to Figure 2-4).

NOTE

Run sensor wiring out of the left opening (From front view) to junction box. All others out right opening to junction box.

2.3.3 Pipe Mounting (P/N 23053-00). The 2 inch pipe

mounting bracket includes a metal plate with a cutout for the analyzer (Refer to Section 2.3 for mounting the analyzer into the plate). Mounting details are shown in Figure 2-5.

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 woring should be 14 guage or greater.

MODEL 1054B LC SECTION 2.0

INSTALLATION

NOTE

For best 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 (Figure 2-6). When wiring to the wall mounting junction box connect the output cable’s outer shield to the earth ground terminal on TB-A (Figure 2-4).

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 on TB-2 (Figure 2-6). 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 (Figure 2-4).

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 ot the instrment and identified as the disconnecting devie 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).

2.5 Sensor Installation. The Model 1054BLC is

designed to work with sensor Models 441, 455, and Endurance line. These cells are of stainless steel construction with titanium-palladium electrodes. Standard 3/4 in. NPT mounting threads are provided on Model 441, 1/4 in. FPT on the Model 455. In these cells the RTD temperature compensator is located within the center element where it makes optimal thermal contact with the process stream. The cells are equipped with integrally connected cable (10 ft standard). Refer to Figure 2-6 for sensor wiring.

For Endurance line sensors, please refer to the Endurance instruction manual.

2.5.1 Cell Location.A mounting location should be

chosen to meet the following considerations:

1. Avoid dead ends or pipe stubs or any location where circulation might be poor.

2. If velocity is very low, mount the cell so that the stream is directed against the end of the electrodes and the water will flow between the electrodes.

3. Be sure that the pipe is full of water and that the cell is completely immersed up to the pipe threads.

4. Cell mounting vertically downward is not recommended due to possible air entrapment.

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 page 18 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.

4.2 PROCESS VARIABLE. Display Mnemonic “tYP”. Used to select display convention of the primary variable and to select the temperature compensation curve.

A. Conductivity. Display Mnemonic “Con”. Select this item to display conductivity in µS/cm.

B. Resistivity. Display Mnemonic “rES”. Select this item to display resistivity in megohms/cm.

C. Neutral Salt. Display Mnemonic “nEu”. Select this item for temperature compensation appropriate for water contaminated with minute quantities of sodium chloride.

C. Cation. Display Mnemonic “CAt”. Select this item for temperature compensation for water contaminated with minute quantities of hydrochloric acid, as would be the case for the effluent from a cation resin column.

4.2.1 Primary Variable Configuration (tYP). Refer to Figure 4-1.

1. Enter Set Mode by pressing ACCESS key twice.

2. SCROLL ( ) until “tYP” appears on the display.

3. SELECT to move to the next menu level. “Con”or “rES” will display.

4. SCROLL ( ) to display desired item then ENTER. “nEu” or “cAt” will display.

5. SCROLL ( ) to display desired item then ENTER. Display will return to “tYP”.

SECTION 5.0

START-UP AND CALIBRATION

5.1 START-UP AND CALIBRATION. Calibration and

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

5.1.1 Entering the Cell Constant. The cell constant is factory set for a .01 cell constant. Ifthe Model 441 or 455 is used, this value need not be changed. If a cell with a constant other than .01 is used, enter the appropriate value as follows:

l. Enter the Set Mode by pressing the ACCESS key

twice in rapid succession. The analyzer will display “SEt”” briefly then display “Cin”.

2. SCROLL ( ) the menu until “CEL””is displayed, then SELECT it. The Numerical display will flash to indicate that a value is desired.

3. Use SCROLL ( ) and SHIFT ( ) to display the cor- rect sensor cell constant and ENTER it into memory.

5.1.2 Entering the Cell Calibration Constant

(Factor). Each Rosemount Analytical Inc. conductivity

cell intended for use with the 1054B LC includes a tag giving its calibration constant, “Cal Const.” This number is between 0 and 999 specifying the cell’s exact cell constant. Entering this value into the 1054B LC allows increased measurement accuracy. Enter the number provided on the Cell’s tag as follows:

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

2. SCROLL ( ) the menu until ““Fct””is displayed, then SELECT it. The Numerical display will flash to indicate that a value is desired.

3. Use SCROLL ( ) and SHIFT ( ) to display the correct calibration constant and ENTER it into memory.

5.1.3 Temperature Calibration. Precise measurement of high purity water requires accurate temperature measurement. For this reason it is recommended that the cell be temperature calibrated.

To calibrate a conductivity cell, place the cell and a high accuracy mercury thermometer into a beaker of water. It is best, though not essential, that the sample be near the temperature of the intended process stream. Allow several minutes for the sensor and thermometer to come to equilibrium.

1. Observe the analyzer temperature reading by pressing TEMPkey. Assure that the reading is st able and the sensor acclimated to the process temperature.

2. Compare the analyzer reading to the thermometer reading. If the readings are different, proceed to Step 3.

4. SCROLL ( ) and SHIFT ( ) to display the correct value and ENTER it into memory.

5.1.4 Cell Single Point Calibration. The “Single Point”

calibration adjustment is for use only in calibrating the Model 1054B LC to match a reference instrument of known high accuracy . To use it otherwise will result in a reduction in system accuracy. By performing a single point calibration, the user overrides the calibration constant setting.

NOTE

To completely undo the single point calibration adjustment, re-enter either the cell constant or cell calibration constant (Section

5.1.1 - 2).

NOTE

After initial installation or any cleaning procedure, the conductivity cell will require I to 2 days after insertion into the ultrapure water stream before accurate readings may be obtained. In many cases, the full 1% system accuracy will not be obtainable until the cell has remained in the ultrapure water stream a full 5 days.

3. Press the CAL key then press the SELECT key.

““Std” will display followed by the Numeric Display with digit flashing.

4. SCROLL ( ) and SHIFT ( ) to display the conduc-

tivity value of known high accuracy and ENTER it into memory.

NOTE

The standardization routine requires entry of a conductivity value, to convert a resistivity value to a conductivity value, divide one by the resistivity value.

7.1 THEORY OF OPERATION. This section is a gen-

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

Utilizing a square wave measurement circuit for improved linearity and accuracy, the Model 1054B LC measures the absolute conductivity/resistivity of the measured process. The analyzer then references the conductivity/resistivity to 25°C by accurately measuring the process temperature by means of a Pt- 1000 RTD located in the cell.

It is commonly known that in measuring the resistivity or conductivity of ultrapure water, temperature compensation is very critical. The temperature coefficient of ultrapure water depends both on the temperature and the resistivity/conductivity of the water being tested. Figure 7-1 illustrates the relationship between the resistance and the temperature of pure water from 2 megohm/cm to 18 megohm/cm quality.

The Model 1054B LC incorporates a 1000 ohm RTD for temperature measurement, and is capable of measuring and displaying temperature accurately to within ±0.1°C. Temperature measurement is resolved to .025°C and this precise measurement is used in the analyzer’s temperature compensation calculation.

For neutral salts the equation that the analyzer utilizes to calculate temperature compensation is derived from the equivalent conductance of the separate ions in the total solution system. The equation is the form of:

- QW)

= C25QS -

(18.25)

Where Ct= Specific conductivity at temperature

C25= Conductivity at 25°C QS= Temperature coefficient of neutral salt QW= Temperature coefficient of pure water

This formula takes into account the temperature coefficient of the neutral salt component and the pure H2O component and separately calculates the conductive contribution of the solvent and solute.

This temperature compensation method not only achieves the same accuracy for water over the range of 15°C to 60°C as the General Electric equation, but also extends the accuracy from 0°C to 100°C.

For Cation resin columns, a formula specific to the characteristics of pure water contaminated with minute quantities of hydrochloric acid is used to provide accuracy for Cation solutions up to 9.99 microSiemens/cm over a temperature range of 0°C to 100°C.

“““FAC””” Factory calibration required.

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. Afault 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 3.85 ohms.

DIAGNOSTICS AND TROUBLESHOOTING

8.2 TROUBLESHOOTING. The Model 1054B analyzer

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

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 3-5.

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 sensor 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. Conductivity cells used in pure water service require little maintenance. As with any type of in-line instrumentation, the cell should be inspected periodically. During these inspections, the following items should be checked:

NOTE

1. Are the cell cable and connections in good condition? Is there evidence of corrosion?

2. Is the cell bent or dented? Blow dry with compressed air and inspect carefully for physical damage.

3. Is there any extraneous material lodged between the electrodes? The cell is easily inspected and can be cleaned with a blast of compressed air or by holding it holder hot tap water. Hot tap water may be run through the cell by slipping a piece of rubber tubing over the end of the cell and allowing the water to flow through the cell and out the vent holes.

For extremely dirty cell, see step 4 on the following page.

MODEL 1054B LC SECTION 8.0

DIAGNOSTICS AND TROUBLESHOOTING

4. If the conductivity cell electrodes have become extremely dirty or fouled, chemical cleaning may become necessary. Warm 10% solutions of either hydrochloric acid or sodium hydroxide may be used depending on the soil. Do not keep cells in these solutions for longer than 15 minutes. Do not have the cell connected during this procedure. Gentle brushing with a bristle brush such as a tooth brush may also be employed.

After chemical cleaning, the cell must be thoroughly rinsed in running tap water to remove strong electrolyte which may remain on the electrodes, insulators and electrode holders. This rinsing operation should continue for approximately one half hour. The cell should then be washed in several changes of distilled or deionized water over a period of several hours before being installed.

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 the ACCESS key twice.

2. “SEt””will be displayed briefly followed by “Cin”.

3. SELECT “Cin” to read the absolute conductivity of cell 1.

4. To return to normal operation, press PV.

Temperature Sensor Accuracy. If the temperature sensor in the conductivity sensor is suspect, measuring the resisteance along 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° change corresponds to a change of 3.85 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 will need to be recalibrated following specific procedures 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, 2, and 3. Install resistors or decade boxes to TB2 -1, 2, and 3 (see Figure 8-1). TB2-1 and TB2-2 are for conductivity input; TB2-2 and TB2-3 are temperature input.

2. Set cell constant to .01 (see Section 5.1.1).

3. Set calibration factor to 500.

4. Adjust temperature to 25°C, or put into manual temperature compensation (see Section 1.1.3)

5. 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).

6. 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 regualar basis using a mild soap and water solution followed by a clean water rinse.
