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. S t andard 0/4-20 m A
current outputs ca n b e programm ed 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.

1.3 Contacting Conductivity (Code -20 and -30)

Section 1.0: Description and Specification

April 2017

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 two contacting conductivity sensors are
used, Model 1056 can derive an inferred pH value
called pHCalc. pHCalc is calculated pH, not directly
measured pH.(Model 1056-0X-20-30-AN required)

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

Measures conductivity in the range of 1 (one) µS/cm to
2,000,000 µS/cm (2 S/cm), Measurement choices are
conductivity, resistivity, total dissolved solids, salinity,
and % concentration. The % concentration selection
includes the choice of five common solutions (0-12%
Na OH, 0-15% HCl, 0-20% Na Cl, and 0-25% or
96-99.7% H2SO4). The conductivity concentration
algorithms for these solutions are fully temperature
compensated. For other solutions, a simple-to-use
menu allows the customer to enter his own data. The
analyzer accepts as many as five data points and fits
either a linear (two points) or a quadratic function (three
or more points) to the data. Two temperature compensation
options are available: manual slope (X%/°C) and neutral
salt (dilute sodium chloride). Temperature compensation
can be disabled, allowing the analyzer to display raw
conductivity. Reference temperature and linear temper­ature slope may also be adjusted for optimum results.

1.5 pH/ORP/ISE (Code -22 and -32)

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 1056 can also derive an inferred pH value called
pHCalc (calculated pH). pHCalc can be derived and
displayed when two contacting conductivity sensors are
used. (Model 1056-0X-20-30-AN)

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 digit al 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.

Figure 3-1

24 VDC Power Supply (-02 ordering code)
is shown below:

This power supply automatically detects DC power and
accepts 20 VDC to 30 VDC inputs.

Four programmable alarm relays are included.

Figure 3-2

Switching AC Power Supply (-03 ordering
code) is shown below:
