1.1 Features and Applications

The 1056 dual-input analyzer offers single or dual sensor input with an unrestricted choice of dual measurements. This multi-parameter instrument offers a wide range of measurement choices supporting most industrial, commercial, and municipal applications. The modular design allows signal input boards to be field replaced making configuration changes easy. Conveniently, live process values are always displayed during programming and calibration routines.

Quick Start Programming: Exclusive Quick Start screens appear the first time the 1056 is powered. The instrument auto-recognizes each measurement board and prompts the user to configure each sensor loop in a few quick steps for immediate deployment.

Digital Communications: HART and Profibus DP digital communications are available. The 1056 HART units communicate with the Model 375 HART held communicator and HART hosts, such as AMS Intelligent Device Manager. Model 1056 Profibus units are fully compatible with Profibus DP networks and Class 1 or Class 2 masters. HART and Profibus DP configured units will support any single or dual measurement configuration of Model 1056.

hand-

Menus: Menu screens for calibrating and programming are simple and intuitive. Plain language prompts and help screens guide the user through these procedures.

Dual Sensor Input and Output: The 1056 accepts single or dual sensor input. Standar d 0/4-20 mA curr e n t ou t puts c a n be programmed to correspond to any measurement or temperature.

Enclosure: The instrument fits standard ½ DIN panel cutouts. The versatile enclosure design supports panel-mount, pipe-mount, and surface/wall-mount installations.

Isolated Inputs: Inputs are isolated from other signal sources and earth ground. This ensures clean signal inputs for single and dual input configurations. For dual input configurations, isolation allows any combination of measurements and signal inputs without cross-talk or signal interference.

Temperature: Most measurements require temperature compensation. The 1056 will automatically recognize Pt100, Pt1000 or 22k NTC RTDs built into the sensor.

Security Access Codes: Two levels of security access are available. Program one access code for routine calibration and hold of current outputs; program another access code for all menus and functions.

4-Electrode Conductivity:

The 1056 is compa tible with Rosem ount 4-electrode Model 410VP in the PUR-SENSE family of conductivity sensors. This sensor supports a wide array of applications and is capable of measuring a large range of conductivity with one geometric configuration. Wired to the 1056, this sensor can measure 2µS/cm to 300mS/cm with an accuracy of 4% of reading throughout the entire range.

4-20mA Current Input: Accepts any analog current input from an external device for temperature compensation of measurements and atmospheric pressure input for partial pressure correction of oxygen.

Selective Ions: The analyzer is able to measure ammonia and fluoride using commercially available ion-selective electrodes. All analyzers with installed pH boards can be programmed to measure selective ions.

Inferential pH: The analyzer is able to derive and display inferred pH (pHCalc) using two contacting conductivity signal boards and the appropriate contacting conductivity sensors. This method will calculate the pH of condensate and boiler water from conductivity and cation conductivity measurements.

Differential Conductivity: Dual input conductivity configurations can measure differential conductivity. The analyzer can be programmed to display dual conductivity as ratio, % rejection, or % passage.

CURRENT OUTPUTS: Two 4-20 mA or 0-20 mA current outputs are electrically isolated. Outputs are fully scalable and can be programmed to linear or logarithmic modes. Output dampening can be enabled with time constants from 0 to 999 seconds. Output 1 includes digital signal 4-20 mA superimposed HART (option -HT only)

1.6 Flow (Code -23 and -33)

For use with most pulse signal flow sensors, the 1056 user-selectable units of measurement include flow rates in GPM (Gallons per minute), GPH (Gallon per hour), cu ft/min (cubic feet per min), cu ft/hour (cubic feet per hour), LPM (liters per minute), LPH (liters per hour), or m3/hr (cubic meters per hour), and velocity in ft/sec or m/sec. When configured to measure flow, the unit also acts as a totalizer in the chosen unit (gallons, liters, or cubic meters).

Dual flow instruments can be configured as a % recovery, flow difference, flow ratio, or total (combined) flow.

Performance Specifications

Frequency Range: 3 to 1000 Hz

Flow Rate: 0 - 99,999 GPM, LPM, m3/hr, GPH, LPH,

cu ft/min, cu ft/hr.

1.7 4-20mA Current Input (Code -23 and -33)

For use with any transmitter or external device that transmits 4-20mA or 0-20mA current outputs. Typical uses are for temperature compensation of live measurements (except ORP, turbidity and flow) and for continuous atmospheric pressure input for determination of partial pressure, needed for compensation of live dissolved oxygen measurements. External input of atmospheric pressure for DO measurement allows continuous partial pressure compensation while the Model 1056 enclosure is completely sealed. (The pressure transducer component on the DO board can only be used for calibration when the case is open to atmosphere.)

Externally sourced current input is also useful for calibration of new or existing sensors that require temperature measurement or atmospheric pressure inputs (DO only).

For externally sourced temp or pressure compensation, the user must program the 1056 to input the 4-20mA current signal from the external device.

In addition to live continuous compensation of live measurements, the current input board can also be used simply to display the measured temperature. or the calculated partial pressure from the external device.

Totalized Flow: 0 – 9,999,999,999,999 Gallons or m3, 0 – 999, 999,999,999 cu ft.

Accuracy: 0.5%

Input filter: time constant 0-999 sec., default 5 sec.

Recommended Sensors*

+GF+ Signet 515 Rotor-X Flow sensor

* Input voltage not to exceed ±36V

This feature leverages the large display variables on the Model 1056 as a convenience for technicians. Temperature can be displayed in degrees C or degrees F. Partial pressure can be displayed in inches Hg, mm Hg, atm (atmospheres), kPa (kiloPascals), bar or mbar.

The current input board can be used with devices that do not actively power their 4-20mA output signals. The Model 1056 actively powers to the + and – lines of the current input board to enable current input from a 4-20mA output device.

Note: this Model 1056 signal input board (23, 33 model option code) also includes flow measurement functionality. The signal board, however, must be configured to measure either mA current input or flow.

Wiring

3.1 General

3.2 Preparing Conduit Openings

3.3 Preparing Sensor Cable

3.4 Power, Output, and Sensor Connections

3.1 General

The 1056 is easy to wire. It includes removable connectors and slide-out signal input boards. The front panel is hinged at the bottom. The panel swings down for easy access to the wiring locations.

3.1.1. Removable connectors and signal input boards

Model 1056 uses removable signal input boards and communication boards for ease of wiring and installation. Each of the signal input boards can be partially or completely removed from the enclosure for wiring. The Model 1056 has three slots for placement of up to two signal input boards and one communication

board.

Slot 1-Left Slot 2 – Center Slot 3 – Right

Comm. board Input Board 1 Input Board 2

3.1.2 Signal Input Boards

Slots 2 and 3 are for signal input measurement boards. Wire the sensor leads to the measurement board following the lead locations marked on the board. After wiring the sensor leads to the signal board, carefully slide the wired board fully into the enclosure slot and take up the excess sensor cable through the cable gland. Tighten the cable gland nut to secure the cable and ensure a sealed enclosure.

3.1.3 Digital Communication Boards

HART and Profibus DP communication boards will be available in the future as options for Model 1056 digital communication with a host. The HART board supports Bell 202 digital communications over an analog 4-20mA current output. Profibus DP is an open communications protocol which operates over a dedicated digital line to the host.

3.1.4 Alarm Relays

Four alarm relays are supplied with the switching power supply (85 to 265VAC, 03 order code) and the 24VDC power supply (20-30VDC, 02 order code). All relays can be used for process measurement(s) or temperature. Any relay can be configured as a fault alarm instead of a process alarm. Each relay can be configured independently and each can be programmed as an interval timer, typically used to activate pumps or control valves. As process alarms, alarm logic (high or low activation or USP*) and deadband are user-programmable. Customer-defined failsafe operation is supported as a programmable menu function to allow all relays to be energized or not-energized as a default condition upon powering the analyzer. The USP* alarm can be programmed to activate when the conductivity is within a user-selectable percentage of the limit. USP alarming is available only when a contacting conductivity measurement board is installed.

3.2 Preparing Conduit Openings

There are six conduit openings in all configurations of Model 1056. (Note that four of the openings will be fitted with plugs upon shipment.)

Conduit openings accept 1/2-inch conduit fittings or PG13.5 cable glands. To keep the case watertight, block unused openings with NEMA 4X or IP65 conduit plugs.

NOTE: Use watertight fittings and hubs that comply with your requirements. Connect the conduit hub to the conduit before attaching the fitting to the analyzer.

3.3 Preparing Sensor Cable

The 1056 is intended for use with all Rosemount sensors. Refer to the sensor installation instructions for details on preparing sensor cables.

3.4 Power, Output, and Sensor Connections

3.4.1 Power Wiring

Three Power Supplies are offered for Model 1056:

a. 115/230 VAC Power Supply (-01 ordering code)

b. 24 VDC (20 – 30V) Power Supply (-02 ordering code)

c. 85 – 265 VAC Switching Power Supply (-03 ordering code)

AC mains (115 or 230 V) leads and 24 VDC leads are wired to the Power Supply board which is mounted vertically on the left side of the main enclosure cavity. Each lead location is clearly marked on the Power Supply board. Wire the power leads to the Power Supply board using the lead markings on the board.

The grounding plate is connected to the earth terminal of power supply input connector TB1 on the -01 (115/230 VAC) and -03 (85-265 VAC) power supplies. The green colored screws on the grounding plate are intended for connection to some sensors to minimize radio frequency interference. The green screws are not intended to be used for safety purposes.

115/230 VAC Power Supply (-01 ordering code) is shown below:

CAUTION

AC Power switch shipped in the 230 VAC position. Adjust switch upwards to 115 VAC position

for 110 VAC – 120 VAC operation.

3.4.2 Current Output Wiring

All instruments are shipped with two 4-20 mA current outputs. Wiring locations for the outputs are on the Main board which is mounted on the hinged door of the instrument. Wire the output leads to the correct position on the Main board using the lead markings (+/positive,

-/negative) on the board. Male mating connectors are provided with each unit.

Note

Twisted pairs are required to minimize noise pickup in

Figure 3-4 4-20 mA current outputs. For high EMI/RFI environments, shielded sensor wire is required and recommended in all other installations.

3.4.3 Alarm Relay Wiring

Four alarm relays are supplied with the switching power supply (85 to 265VAC, -03 order code) and the 24VDC power supply (20-30 VDC, -02 order code). Wire the relay leads on each of the independent relays to the correct position on the power supply board using the printed lead markings (NO/Normally Open, NC/Normally Closed, or Com/Common) on the board. See Fig 3-4.

3.4.4 Sensor Wiring to Signal Boards

Wire the correct sensor leads to the measurement board using the lead locations marked directly on the b o a r d . After wiring the sensor leads to the signal board, carefully slide the wired board fully into the enclosure slot and take up the excess sensor cable through the cable gland.

For best EMI/RFI protection use shielded output signal cable enclosed in an earth-grounded metal conduit. Connect the shield to earth ground. AC wiring should be 14 gauge or greater. Provide a switch or breaker to disconnect the analyzer from the main power supply. Install the switch or breaker near the analyzer and label it as the disconnecting device for the analyzer.

Keep sensor and output signal wiring separate from power wiring. Do not run sensor and power wiring in the sameconduit or close together in a cable tray.

NOTE:

Twisted pairs are required to minimize noise pickup in the flow and current sensor inputs. For high EMI/RFI environments, shielded sensor wire is required and recommended in all other installations.

5.3 Choosing Temperature Units And Automatic/Manual Temperature Compensation

5.3.1 Purpose

Most liquid analytical measurements (except ORP) require temperature compensation. The Model 1056 performs temperature compensation automatically by applying internal temperature correction algorithms. Temperature correction can also be turned off. If temperature correction is off, the Model 1056 uses the temperature entered by the user in all temperature correction calculations.

5.3.2 Procedure

Follow the menu screens in Fig. 5.1 to select automatic or manual temp compensatio n, set the manual reference temperature, and to program temperature units as °C or °F.

Figure 5-1. Choosing Temp Units and Manual Auto Temp Compensation

S2: 12.34pH 25.0ºC

Temperature Units: °C S1 Temp Comp: Auto S2 Temp Comp: Auto S1 Manual: +25.0°C

S2 Manual: +25.0ºC

5.4 Configuring and Ranging The Current Outputs

5.4.1 Purpose

The Model 1056 accepts inputs from two sensors and has two analog current outputs. Ranging the outputs means assigning values to the low (0 or 4 mA) and high (20 mA) outputs. This section provides a guide for configuring and ranging the outputs. ALWAYS CONFIGURE THE OUTPUTS FIRST.

5.4.2 Definitions

1. CURRENT OUTPUTS. The analyzer provides a continuous output current (4-20 mA or 0-20 mA) directly proportional to the process variable or temperature.

The low and high current outputs can be set to any value.

2. ASSIGNING OUTPUTS. Assign a measurement to Output 1 or Output 2.

3. DAMPEN. Output dampening smooths out noisy readings. It also increases the response time of the output. Output dampening does not affect the response time of the display.

4. MODE. The current output can be made directly proportional to the displayed value (linear mode) or directly proportional to the common logarithm of the displayed value (log mode).

6.1 Programming Measurements – Introduction

The Model 1056 automatically recognizes each installed measurement board upon first power-up and each time the analyzer is powered. Completion of Quick Start screens upon first power up enable measurements, but additional steps may be required to program the analyzer for the desired measurement application. This section covers the following programming and configuration functions;

1. Selecting measurement type or sensor type (all sections)

2. Identifying the preamp location (pH-see Sec. 6.2)

3. Enabling manual temperature correction and entering a reference temperature (all sections)

4. Enabling sample temperature correction and entering temperature correction slope (selected sections)

5. Defining measurement display resolution (pH and amperometric)

6. Defining measurement display units (all sections)

7. Adjusting the input filter to control display and output reading variability or noise (all sections)

8. Selecting a measurement range (conductivity – see Sec’s 6.4, 6.5)

9. Entering a cell constant for a contacting or toroidal sensor (see Sec’s 6.4, 6.5)

10. Entering a temperature element/RTD offset or temperature slope (conductivity-see Sec’s 6.4)

11. Creating an application-specific concentration curve (conductivity-see Sec’s 6.4, 6.5)

12. Enabling automatic pH correction for free chlorine measurement (Sec. 6.6.1)

To fully configure the analyzer for each installed measurement board, you may use the following:

1. Reset Analyzer function to reset factory defaults and configure the measurement board to the desired measurement. Follow the Reset Analyzer menu (Fig. 5-5) to reconfigure the analyzer to display new measurements or measurement units.

2. Program menus to adjust any of the programmable configuration items. Use the following configuration and programming guidelines for the applicable measurement.

7.1 Calibration – Introduction

Calibration is the process of adjusting or standardizing the analyzer to a lab test or a calibrated laboratory instrument, or standardizing to some known reference (such as a commercial buffer).

The auto-recognition feature of the analyzer will enable the appropriate calibration screens to allow calibration for any single sensor configuration or dual sensor configuration of the analyzer. Completion of Quick Start upon first power up enables live measurements but does not ensure accurate readings in the lab or in process. Calibration should be performed with each attached sensor to ensure accurate, repeatable readings.

This section covers the following programming and configuration functions:

1. Auto buffer cal for pH (pH Cal - Sec.7.2)

2. Manual buffer cal for pH (pH Cal - Sec.7.2)

3. Set calibration stabilization criteria for pH (pH Cal -

Sec.7.2)

4. Standardization calibration (1-point) for pH, ORP and Redox (pH Cal - Sec.7.2 and 7.3)

5. Entering the cell constant of a conductivity sensor (Conductivity Cal - Sec. 7.4 and 7.5)

6. Calibrating the sensor in a conductivity standard Conductivity Cal - Sec. 7.4 and 7.5)

7. Calibrating the analyzer to a laboratory instrument (Contacting Conductivity Cal - Sec.7.4)

8. Zeroing an chlorine, oxygen or ozone sensor (Amperometric Cal - Sec’s 7.6, 7.7, 7.8)

9. Calibrating an oxygen sensor in air (Oxygen Cal

- Sec’s 7.6)

10. Calibrating the sensor to a sample of known

concentration (Amperometric Cal - Sec’s 7.6, 7.7, 7.8)

11. Enter a manual reference temperature for temperature compensation of the process measurement

7.2 pH Calibration

7.2.1 Description

New sensors must be calibrated before use. Regular recalibration is also necessary. Use auto calibration instead of manual calibration. Auto calibration avoids common pitfalls and reduces errors. The analyzer recognizes the buffers and uses temperature-corrected pH values in the calibration. Once the Model 1056 successfully completes the calibration, it calculates and displays the calibration slope and offset. The slope is reported as the slope at 25°C.

7.2.5 Standardization — pH

The pH measured by the Model 1056 analyzer can be changed to match the reading from a second or referee instrument. The process of making the two readings agree is called standardization. During standardization, the difference between the two pH values is converted to the equivalent voltage. The voltage, called the reference offset, is added to all subsequent measured cell voltages before they are converted to pH. If a standardized sensor is placed in a buffer solution, the measured pH will differ from the buffer pH by an amount equivalent to the standardization offset.

New conductivity sensors rarely need calibration. The cell constant printed on the label is sufficiently accurate for most applications. The cell constant should be entered:

• When the unit is installed for the first time

• When the probe is replaced

• During troubleshooting This procedure sets up the analyzer for the probe type connected to the analyzer. Each type of probe has a specific cell constant:

7.5.4 Calibrating The Sensor In A Conductivity Standard (In Process Cal)

This procedure is used to check and correct the conductivity reading of the Model 1056 to ensure that the reading is accurate. This is done by submerging the probe in the sample of known conductivity, then adjusting the displayed value, if necessary, to correspond to the conductivity value of the sample. The probe must be cleaned before performing this procedure. The temperature reading must also be checked and standardized if necessary, prior to performing this procedure.

7.6 Calibration — Chlorine

With a Chlorine measurement board and the appropriate sensor, Model 1056 can measure any of four variants of Chlorine:

• Free Chlorine

• Total Chlorine

• Monochloramine

• pH-independent Free Chlorine

The section describes how to calibrate any compatible amperometric chlorine sensor. The following calibration routines are covered in the family of supported Chlorine sensors:

• Air Cal

• Zero Cal

• In Process Cal

7.6.1 Calibration — Free Chlorine

7.6.1.1 Description

A free chlorine sensor generates a current directly proportional to the concentration of free chlorine in the sample. Calibrating the sensor requires exposing it to a solution containing no chlorine (zero standard) and to a solution containing a known amount of chlorine (full-scale standard). The zero calibration is necessary because chlorine sensors, even when no chlorine is in the sample, generate a small current called the residual current. The analyzer compensates for the residual current by subtracting it from the measured current before converting the result to a chlorine value. New sensors require zeroing before being placed in service, and sensors should be zeroed whenever the electrolyte solution is replaced. Either of the following makes a good zero standard:

• Deionized water containing about 500 ppm sodium chloride. Dissolve 0.5 grams (1/8 teaspoonful) of table salt in 1 liter of water. DO NOT USE DEIONIZED WATER ALONE FOR ZEROING THE SENSOR. THE CONDUCTIVITY OF THE ZERO WATER MUST BE GREATER THAN 50 μS/cm.

• Tap water known to contain no chlorine. Expose tap water to bright sunlight for at least 24 hours. The purpose of the In Process calibration is to establish the slope of the calibration curve. Because stable chlorine standards do not exist, the sensor must be calibrated against a test run on a grab sample of the process liquid. Several manufacturers offer portable test kits for this purpose. Observe the following precautions when taking and testing the grab sample.

• Take the grab sample from a point as close to the sensor as possible. Be sure that taking the sample does not alter the flow of the sample to the sensor. It is best to install the sample tap just downstream from the sensor.

• Chlorine solutions are unstable. Run the test immediately after taking the sample. Try to calibrate the sensor when the chlorine concentration is at the upper end of the normal operating range.

7.6.2 Calibration — Total Chlorine

7.6.2.1 Description

Total chlorine is the sum of free and combined chlorine. The continuous determination of total chlorine requires two steps. First, the sample flows into a conditioning system (TCL) where a pump continuously adds acetic acid and potassium iodide to the sample. The acid lowers the pH, which allows total chlorine in the sample to quantitatively oxidize the iodide in the reagent to iodine. In the second step, the treated sample flows to the sensor. The sensor is a membrane-covered amperometric sensor, whose output is proportional to the concentration of iodine. Because the concentration of iodine is proportional to the concentration of total chlorine, the analyzer can be calibrated to read total chlorine. Because the sensor really measures iodine, calibrating the sensor requires exposing it to a solution containing no iodine (zero standard) and to a solution containing a known amount of iodine (full-scale standard). The Zero calibration is necessary because the sensor, even when no iodine is present, generates a small current called the residual current. The analyzer compensates for the residual current by subtracting it from the measured current before converting the result to a total chlorine value. New sensors require zeroing before being placed in service, and sensors should be

zeroed whenever the electrolyte solution is replaced. The best zero standard is deionized water.

The purpose of the In Process Calibration is to establish the slope of the calibration curve. Because stable total chlorine standards do not exist, the

sensor must be calibrated against a test run on a grab sample of the process liquid. Several manufac-

turers offer portable test kits for this purpose. Observe the following precautions when taking and testing the grab sample:

• Take the grab sample from a point as close as possible to the inlet of the TCL sample conditioning system. Be sure that taking the sample does not alter the flow through the TCL.

• Chlorine solutions are unstable. Run the test immediately after taking the sample. Try to calibrate the sensor when the chlorine concentration is at the upper end of the normal operating range.

Note this measurement must be made using the Model TCL total chlorine sample conditioning system.
