1.1 Features and Applications

The Model 1057 analyzer offers three sensor inputs and four current outputs thus reducing the cost per loop and saving panel space. The pH signal input board supports pH, ORP, and Ion-Selective Electrode measurements. The conductivity signal input board supports contacting conductivity, resistivity, total dissolved solids, salinity and percent concentration curves for special 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. Standard features include isolated inputs, eight embedded local languages, four 4-20mA current outputs, four alarm relays and removable connectors for power and current outputs.

Quick Start Programming: Exclusive quick start screens appear the first time the Model 1057 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.

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

4-Electrode Conductivity: For applications requiring wide range conductivity measurements, use Rosemount Model 410VP 4-electrode sensor. It is not affected by fouling and is supported by the same contacting conductivity signal board as traditional 2-electrode sensors.

Three Sensor Inputs: The Model 1057 accepts one, two or three isolated inputs. Inputs are isolated from other signal sources and earth ground.

Four Current Outputs: Four 0/4-20 mA current outputs are electrically isolated. Outputs are fully scalable and can be programmed to linear or logrithmic modes. Output dampening can be enabled with time constants from 0 to 999 seconds.

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

Smart pH Sensors: Avoid buffer calibrations in the field. Use Rosemount SMART pH sensors to automatically calibrate the measurement loop when connected to Model 1057. Choose from a complete range of SMART pH sensors suited to most applications.

1.3 Contacting Conductivity (Codes -20, -30 and -40)

Measures conductivity in the range 0 to 600,000 µS/cm (600mS/cm). Measurement choices are conductivity, resistivity, total dissolved solids, salinity, and % concentration. The % concentration selection includes the choice of five common solutions (0-12% NaOH,0-15% HCl, 0-20% NaCl, and 0-25% or 96-99.7% H2SO4). The conductivity concentration algorithms for these solutions are fully temperature compensated. Three temperature compensation options are available: manual slope (X%/°C), high purity water (dilute sodium chloride), and cation conductivity (dilute hydrochloric acid). Temperature compensation can be disabled, allowing the analyzer to display raw conductivity. For more information concerning the use and operation of the contacting conductivity sensors, refer to the product data sheets.

Note: When contacting conductivity sensors are used for sensor 1 and sensor 2, Model 1057 can derive an inferred pH value called pHCalc. pHCalc is calculated pH, not directly measured pH.

Note: Selected 4-electrode, high-range contacting conductivity sensors are compatible with Model 1056.

Input filter: time constant 1 - 999 seconds, default 2 seconds Response time: 3 seconds to 100% of final reading Salinity: Uses Practical Salinity Scale

1.4 pH/ORP/ISE (Codes -22, -32, and -42)

For use with any standard pH or ORP sensor. Measurement choices are pH, ORP, Redox, ammonia, fluoride or custom ISE. The automatic buffer recognition feature uses stored buffer values and their temperature curves for the most common buffer standards available worldwide. The analyzer will recognize the value of the buffer being measured and perform a self stabilization check on the sensor before completing the calibration. Manual or automatic temperature compensation is menu selectable. Change in pH due to process temperature can be compensated using a programmable temperature coefficient. For more information concerning the use and operation of the pH or ORP sensors, refer to the product data sheets.

Model 1057 can also derive an inferred pH value called pHCalc (calculated pH). pHCalc can be derived and displayed when two contacting conductivity sensors are used as sensor 1 and sensor 2.

3.1 General

The Model 1057 is easy to wire. It includes removable connectors and slide-out signal input boards.

3.1.1 Removable Connectors and Signal Input Boards

Model 1057 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 1057 has three slots for placement of up to three

signal input boards and one communication board.

March 2020

Slot 1 – Left

Signal board 3

Note: If the UL option code has been ordered, a plastic insulator shield surrounds the entire power supply board (AC power supply only). The protective insulator shield does not appear in this photo.

3.1.2 Signal Input Boards

Slots 1, 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. Note: that signal input board 3 is inserted into slot 1. Board 3 is inverted in the slot to allow board components to face to the right. Board 3 uses a long ribbon cable to connect to the main PCB. Boards 1 and 2 use a split ribbon cable to connect both signal boards to a common connector on the main board.

3.1.3 Alarm Relays

Four alarm relays are supplied with the switching power supply (84 to 265 Vac, 03 order code) and the 24 Vdc power supply (20-30 Vdc, 02 order code). All relays can be used for process measure ments 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 acti vation 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 1057. (Note that four plugs are provid-

ed upon shipment.)

Note: Use watertight fittings and hubs that comply with your requirements. Connect the conduit

ub to the conduit before attaching the fitting to the analyzer.

3.3 Preparing Sensor Cable

The Model 1057 is intended for use with all Rosemount pH/ORP and contacting conductivity sensors. Refer to the sensor installation instructions for details on preparing sensor cables.

3.4 Power, Output and Sensor Connections

All field wiring must be rated for 75 °C or higher. Each instrument includes a printed label inside the enclosure stating this wiring requirement.

3.4.1 Power Wiring

Two Power Supplies are offered for Model 1057:

a. 24 Vdc (20 – 30V) Power Supply (-02 ordering code)

b. 84 – 265 Vac Switching Power Supply (-03 ordering code)

AC mains (115 or 230V) 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.

5.4 Configuring and Ranging The Current Outputs

5.4.1 Purpose

The Model 1057 accepts inputs from three sensors and has four 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 ouputs - 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 outputs 1, 2, 3, or 4.

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).

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

2. Identifying the preamp location (pH - see Section 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)

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

9. Entering a cell constant for a contacting sensor (see Section 6.4)

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

11. Creating an application-specific concentration curve (conductivity - see Section 6.4)

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 (Figure 5-5) to reconfigure the analyzer to display new measurements or measurement units.

7.1 Calibration - Introduction

alibration is the process of adjusting or standardizing the analyzer to a lab test or a calibrated

C 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 -

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 1057 successfully completes the calibration, it calculates and displays the calibration slope and offset. The slope is reported as the slope at 25 °C. This section describes how to calibrate

the model 1057 with a ph sensor. the following cali-

7.2.5 Standardization — pH

The pH measured by the Model 1057 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 volt age. 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.

7.4 Contacting Conductivity Calibration

7.4.1 Description

This section describes how to calibrate a Model 1057 with Contacting Conductivity Sensor attached.

Placing A New Conductivity Sensor In Service

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

Calibrating An In-Service Conductivity Sensor

After a conductivity sensor has been in service for a period of time, recalibration may be necessary. There are three ways to calibrate a sensor.

1. Use a standard instrument and sensor to measure the conductivity of the process stream. It is not necessary to remove the sensor from the process piping. The temperature correction used by the standard instrument may not exactly match the temperature correction used by the Model 1057. To avoid errors, turn off temperature correction in both the analyzer and the standard instrument.

2. Place the sensor in a solution of known conductivity and make the analyzer reading match the conductivity of the standard solution. Use this method if the sensor can be easily removed from the process piping and a standard is available. Be careful using standard solu tions having conductivity less than 100 µS/cm. Low conductivity standards are highly sus ceptible to atmospheric contamination. Avoid calibrating sensors with 0.01/cm cell con stants against conductivity standards having conductivity greater than 100 µS/cm. The resistance of these solutions may be too low for an accurate measurement. Calibrate sen sors with 0.01/cm cell constant using method 3.

3. To calibrate a 0.01/cm sensor, check it against a standard instrument and 0.01/cm sensor while both sensors are measuring water having a conductivity between 5 and 10 µS/cm. To avoid drift caused by absorption of atmospheric carbon dioxide, saturate the sample with air before making the measurements.

To ensure adequate flow past the sensor during calibration, take the sample downstream from the sensor. For best results, use a flow-through standard cell. If the process temperature is much different from ambient, keep connecting lines short and insulate the flow cell.

7.4.3 Zeroing The Instrument

This procedure is used to compensate for small offsets to the conductivity signal that are present even when there is no conductivity to be measured. This procedure is affected by the length of extension cable and should always be repeated if any changes in extension cable or sensor have been made. Electrically connect the conductivity probe as it will actually be used and place the measuring portion of the probe in air. Be sure the probe is dry.
