Introduction
1 Introduction
1.1 Overview
Multi-function instrument
The UDA2182 Universal Dual Analyzer is the next level of dual channel analyzers
providing unprecedented versatility and flexibility.
The UDA2182 can accept single or dual inputs from Honeywell Direct pH, pH from
preamp, ORP (Oxidation Reduction Potential), Contacting Conductivity and Dissolved
Oxygen sensors. Measurements for Dual channel units can be arranged in any
combination of measurement.
User interface
“Process Information at a Glance” is a unique feature of the UDA2182 graphical
backlit LCD.
Two PV values with corresponding UOM (unit of measure), temperature, alarm state,
scales, and limits, tagging, and status messages can be displayed simultaneously.
Ten dedicated keys provide direct access to Setup configuration menus and sub-menus
and Calibration.
Easy to configure
Menu-driven configuration of the UDA2182 is intuitive, fast and easy. A Setup menu is
provided for every configuration task. You will be permitted to configure only those
parameters relevant to your application and supported by the Analyzer model you
purchased.
In fact, Setup configuration screens will contain only prompts and menu choices that
apply to your application.
Multi-language prompts guide the operator step-by-step through the configuration
process assuring quick and accurate entry of all configurable parameters. Nine languages
are available via configuration: English, French, German, Spanish, Italian, Russian,
Turkish, Polish and Czech.
Inputs
Analytical measurements of Direct pH, pH from preamp, ORP, Conductivity and
Dissolved Oxygen (ppm or ppb) can all be done in one analyzer. The unit can be used as
a single input or dual input instrument – you decide what measurements are included.
The input boards are factory calibrated and easily replaced. Addition of additional relays
or an analog output is done with a single board. The “Mix –n- Match” design reduces
inventory and increases flexibility. You can purchase a basic unit and then add input and
output boards as needed.
January 2009 UDA2182 Universal Dual Analyzer Product Manual 1
Introduction
Outputs
Two standard Analog outputs 0 –20 or 4–20 mAdc, 750 ohms maximum, isolated from
inputs, ground, and each other, and independently assignable to any parameters and
ranges Proportional to user-set output range(s) of selected parameter(s).
One optional Analog output 0 –20 or 4–20 mAdc, 750 ohms maximum, isolated from
inputs, ground, and each other, and independently assignable to any parameters and
ranges.
Relays
Two 4A SPDT alarm/control relays are standard; with an additional two 4A relays
available as an option.
Infrared Communications
The infrared connection provides a non-intrusive wireless connection with the instrument
and maintains its weather tight integrity when combined with the optional PIE (Process
Instrument Explorer).
No need to get access to the back of the analyzer to communicate with the instrument, no
need to take your screw driver to wire the communication cable, no wiring mistake
possible. You can now duplicate an instrument’s configuration, upload or download a
new configuration in a matter of seconds, just by pointing your Pocket PC in the direction
of the instrument.
Communications Card (Optional)
The Communication card provides one Serial Port and one Ethernet Port.
Serial port provides
RS422/RS485 multi-drop
Modbus RTU protocol to read signals and read/write variables
Ethernet port provides:
Multi-language web pages to monitor readings, alarms, statuses, events
Multi-language web pages to setup Ethernet port settings
Multi-language email to send alarm status changes
Modbus TCP protocol to read signals and read/write variables
Both ports can communicate to a PIE tool

Introduction
1.2 Features
Standard and solution temperature compensation
Measured pH temperature is compensated in one of two ways. Electrode temperature
sensitivity is automatically compensated to display the correct pH value at temperature.
In addition, displayed pH can be optionally normalized to a solution temperature of 25°C
as determined by the current Solution Temperature Coefficient, which is expressed in
units of pH/°C with precision to the hundredths decimal place. The parameter “Solu
Temp Coeff” allows the selection of Pure Water, Ammonia, Phosphate, Morpholine, and
Custom or None (User Entry).
Measured Conductivity and Resistivity can optionally be temperature compensated to
25°C for a specific solution type. TDS and concentration are always measured based on a
specific solution type. The cell constant and measurement type determines which solution
types are available for selection.
Dissolved Oxygen accurately measures the concentration of dissolved oxygen in water.
The Analyzer energizes the probe and receives dissolved oxygen and temperature signals.
Optional salinity compensation is provided. The Analyzer provides for Air or Sample
calibration with ambient temperature and atmospheric pressure compensation.
Calculated pH
High purity water pH can be calculated from Specific and Cation conductivities to be
used as a check on in-line high purity water pH measurements.
Automatic buffer recognition
“Buffer Group” types NIST/USP, USA, or Europe determines the set of standard pH
buffer values to be used for Zero and Slope calibration by automatic buffer recognition.
Each of the available Buffer Groups is a set of 5 or 6 pH buffer standards.
Solution Temperature Compensation
For high purity water measurement you can select pre-set compensations or configure
custom values.
USP26 Alarm Capabilities
Relays can be configured to alarm on conductivity values as determined by the USP26
standards.
Computed Variables
The availability of calculated variables in the list of available sources for alarms, math
and control and for status display is determined by similarity of units of measure between
the two input boards. For example with Dual Conductivity, %Rejection/Passage,
Difference, or Ratio can be displayed and assigned to the outputs or alarms.
CO2 concentration in ppm can be calculated from de-gassed conductivity measurement.

Introduction
Password protection
Keyboard security protects configuration and calibration data. A password (up to four
digits) can be configured. If the security feature is enabled, the password will be required
to access configuration and calibration software functions.
Auto Clean/Auto Cal
Built-in real time clock is used to set-up versatile cycles that can be used to initiate
automatic sensor cleaning and then calibration.
Diagnostic/Failsafe Outputs
Continuous diagnostic routines detect failure modes, trigger a failsafe output value and
identify the failure to minimize troubleshooting time. The UDA2182 Analyzer performs
extensive self-diagnostics as a background task during normal operation. If a problem is
detected, a message is displayed on the Message stripe to alert the operator. In addition,

4.1 Overview
Introduction
This section contains instructions for installing ac power wiring for the Analyzer, in
preparation for performing configuration setup as described in Section 6.
We recommend that you wait to install input and output wiring (See Section 7) until after
Configuration Setup. During configuration the software will determine for you, which
relay to use for each feature.

Power Wiring
4.2 General Wiring Practices
WARNING
Safety precaution
Qualified personnel should perform wiring only.
WARNING
A disconnect switch must be installed to break all current
carrying conductors. Turn off power before working on
conductors. Failure to observe this precaution may result in
serious personal injury.
WARNING
An external disconnect switch is required for any hazardous
voltage connections to the relay outputs.
Avoid damage to components
ATTENTION
This equipment contains devices that can be damaged by electrostatic discharge (ESD). As
solid-state technology advances and as solid-state devices get smaller and smaller, they
become more and more sensitive to ESD. The damage incurred may not cause the device to
fail completely, but may cause early failure. Therefore, it is imperative that assemblies
containing static sensitive devices be carried in conductive plastic bags. When adjusting or
performing any work on such assemblies, grounded workstations and wrist straps must be
used. If soldering irons are used, they must also be grounded.
A grounded workstation is any conductive or metallic surface connected to an earth ground,
such as a water pipe, with a 1/2 to 1 megohm resistor in series with the ground connection. The
purpose of the resistor is to current limit an electrostatic discharge and to prevent any shock
hazard to the operator. The steps indicated above must be followed to prevent damage and/or
degradation, which may be induced by ESD, to static sensitive devices.
Wiring for immunity compliance
In applications where either the power, input or output wiring are subject to
electromagnetic disturbances, shielding techniques will be required. Grounded metal
conduit with conductive conduit fittings is recommended.
Connect the AC mains through a fused disconnect switch.
Conform to code
Instrument wiring should conform to regulations of the National Electrical Code.
16 UDA2182 Universal Dual Analyzer Product Manual January 2009
Power Wiring
4.3 Power Wiring Considerations
Recommended wire size
Observe all applicable electrical codes when making power connections. Unless locally
applicable codes dictate otherwise, use 14-gauge (2.081 mm
including protective earth.
Power supply voltage and frequency within specs
The power supply voltage and frequency must be within the limits stated in the
specifications in Section 2.
4.4 Installing Power Wiring
Procedure
WARNING
Turn power off at mains before installing AC Power Wiring.
Do not remove boards with power ON.
WARNING
The ground terminal must be connected to a reliable earth
ground for proper operation and to comply with OSHA and
other safety codes. If metal conduit is used, connect a bonding
wire between conduits. Do not rely upon the conductive coating
of the instrument case to provide this connection. Failure to
observe this precaution may result in serious personal injury.
