Section 1 General Description
Read this section of the manual to determine the appropriate system
configuration for your operation, and to familiarize yourself with basic
operating instructions before installing the AquaTrend
A Glossary of terms is provided on page 81 to help you understand the
AquaTrend Network.
1.1 Introduction
Hach’s AquaTrend Interface network system is designed to meet the needs of
small and large water analysis facilities alike. Unlike using a dedicated
controller for every instrument, the AquaTrend Interface network system uses
a single AquaTrend Module to interface a variety of devices. This enables
customization of systems to meet a variety of analytical testing needs. The
AquaTrend Interface network system utilizes a digital fieldbus communication
protocol called LonWorks to perform network operations and data
management tasks. Every device on an AquaTrend Interface network must be
identifiable in order to communicate with other AquaTrend Interface
network devices.
An AquaTrend Interface network system is built by adding an AquaTrend
Module to a sensor with a power supply and any other Hach peripheral
devices. Power and network connections are required for all AquaTrend
Interface devices operating on the network. After physically installing the
devices, you must add each device to the AquaT rend Interface network via the
network menus in the Master AquaTrend Interface. After adding all devices to
the network, you must designate which devices communicate with one
another. For example, once a sensor is attached to an AquaTrend Interface,
you must instruct the sensor to attach its reading to a designated AquaTrend
Interface display channel. Because many underlying network connections
occur when performing network operations, it is important to have all existing
devices on the network powered and operating normally when network
operations are conducted. Careful attention to network management
operations and the interconnection of devices will ensure successful operation
of the AquaTrend Interface network system.

1.2 Using This Manual
This manual includes setup and operating instructions for AquaTrend
Interface, AquaTrend/SOM with integrated Signal Output Module, and
Portable AquaTrend Interface. If you are installing an AquaTrend/SOM and
want to include relay and analog output connections, see the Signal Output
Module (SOM) manual for information on making electrical connections.
Once you have gathered the necessary information to set up the AquaTrend
Interface and related sensors, read all instructions and warnings in Section 5
then proceed with the installation.
After making electrical and mechanical adjustments, read Section 2 to decide
which devices to include on the network. Then read and follow instructions in
Section 3 to set up communications between the AquaTrend Interface and
other network devices.

1.5 AquaTrend Interface Menu Organization
The AquaTrend Interface main menu can be accessed at any time by
pressing the MENU key. The main menu categories are described in the
following sections.
1.5.1 Alarm Log
The alarm log menu provides a historical account of sensor specific alarm
information as well as AquaTrend Interface network alarm information.
1.5.2 AquaTrend Interface Menu
The AquaTrend Interface menu provides access to AquaTrend Interface
display and status settings. Display settings, language selection, time and
date settings, and security settings all reside in the AquaTrend Interface
menu. Access this menu to change the way information appears on the
AquaTrend Interface screen.
1.5.3 Sensor Menu
The sensor menu contains all sensor specific information including
calibration, alarm and recorder setup, measurement options, and sensor
diagnostics. The contents of this menu will change based on the sensor you
are working with. Since all of these menu items are stored within the sensor,
they are designed to be sensor specific. Access this menu to change sensor
settings or information.
1.5.4 Other Device Menu
1.5.5 Network Menu
The other device menu contains information specific to accessory devices
that are not sensors. Such examples include Signal Output Modules, Serial
I/O Modules and Digital Display Modules. Access this menu to change
settings or information for non-sensor devices.
The network menu contains information specific to performing network
operations. This includes adding, removing, and replacing devices on the
network. In addition, it contains menu items needed to establish
communications between devices. For example, once a sensor and Digital
Display Module are added to the system via the AquaTrend Interface, you
must instruct the sensor to attach its reading to the Digital Display Module.
Because many underlying network connections occur when performing
network operations, it is important to have all existing devices on the network
powered and operating normally when network operations are conducted.
Section 3 and Section 4 of this manual describe how to use these menus
together to build and configure your network.

Section 2 Aquatrend® Interface Network
2.1 Network Description
This section describes requirements and options for setting up the AquaTrend
Interface Network System. A “network” is the connection of one or more
devices (of which at least one is a sensor) to a Master AquaTrend Interface.
This Master AquaTrend Interface serves as the network control panel.
Devices can include Signal Output Modules (SOM), Digital Display Modules
(DDM), Serial I/O Modules (SIO), Remote AquaTrend Interf aces and
Portable AquaTrend Interfaces.

2.2 Device Descriptions
2.2.1 AquaTrend Interface Module
The two primary functions of the AquaTrend Interface are network
management and data display. Network management functions are required
only when performing modifications to the network such as adding or
removing devices. Multiple AquaTrend Interfaces (up to nine) can exist on a
network at any given time. Remote AquaT rend Interfaces serve to display data
from one or more sensors and access sensor menus.
• Master AquaTrend Interface – Acts as the main network data control
center for setup and operation of the network. The network can contain as
many as nine AquaTrend Interfaces but only one can be the Master
AquaTrend Interface. Only through the Master AquaTrend Interface can
network operations be performed.
• Remote AquaTrend Interface – Any AquaTrend Interface on a network
that is not a Portable or Master AquaTrend Interface. Remote AquaTrend
Interfaces can control and monitor all sensors on the network. Remote
AquaTrend Interfaces cannot perform network operations such as adding
and removing devices.
• Portable AquaTrend Interface – Mobile device designed for set up and
calibration of sensors already on the network. Portable AquaTrend
Interfaces can communicate with one sensor at a time and cannot
perform network operations. See section 2.2.3 and 5.2 for more
information about the Portable AquaTrend Interface.
All AquaTrend Interfaces have the capability of functioning as a Master or
Remote however, only the Master AquaTr end Interface is allowed to perform
network management functions. All AquaTrend Interfaces are shipped from
the factory in an undefined (neither Master or Remote) state. When an
individual AquaTrend Interface is defined as the Master, any other AquaTrend
Interface on the network must be defined as a Remote. An AquaTrend
Interface can be redefined (i.e., Remote to Master or Master to Remote);
however , e xisting network connection information will be lost. After changing a
Remote to a Master AquaTrend Interface, you must rebuild the network and
reestablish communications between devices.
2.2.2 AquaTrend/SOM with Integrated Signal Output Module
The AquaT rend/SOM Module is a combined AquaTrend Interface and SOM in
one enclosure. See section 2.2.1 for information concerning the functions and
options for the AquaTrend Interface portion of the combined AquaTrend/SOM
and section 2.2.5 for more details about the SOM.

51350-18 Aquatrend Interface Network.fm
2.2.3 Portable AquaTrend Interface Module
The Portable AquaTrend Interface can access sensor menus for setup and
calibration but cannot perform network management functions. The Portable
AquaTrend Interface communicates directly to the sensor that it is attached to
without interpreting network commands from the Master AquaT rend Interface.
Once a network is configured using a Master AquaTrend Interface, the
Portable AquaTrend Interface can be used to display and log data from that
sensor in the absence of a Master AquaTrend Interface.
2.2.4 Sensor
The sensor, such as the 1720D Turbidimeter (shown at left), is the
device that analyzes the sample. Sensors may or may not contain an
AquaTrend Interface.
Section 2
2.2.5 Signal Output Module (SOM)
Each SOM provides two relays, each with normally open and normally closed
contacts rated at a maximum of 5A/250 VAC, and two analog outputs,
selectable through the AquaTrend Interface keypad at either 4-20 or 0-20 mA.
Signal Output Module functionality can be provided either in an
AquaTrend/SOM or in a separate Signal Output Module. See the
Output Module Manual
2.2.6 Signal Input Module
The Signal Input Module (SIM) is configured as a sensor on the network
system and provides two 4-20mA analog inputs. These inputs can be used to
bring measurements from non-networked sensors into the network. The SIM
allows the user to set the value for zero and full-scale inputs and to define the
measurement names, units, and species. Two configurable setpoint alarms
can be set to trigger relays in a Signal Output Module. Refer to the
Input Module (SIM) Manual
2.2.7 Serial I/O Module (SIO)
The AquaTrend Interface allows the review of data collected over the last 60
minutes, 24 hours, or 30 days. To download the data to a computer or printer,
a Serial I/O (SIO) Module must be installed. The SIO provides two-way
communication with a computer (PC) or one-way communication with a
printer. Use an SIO to permanently log measurement and diagnostic data to a
printer or computer. See the
for detailed information.

2.2.8 Digital Display Module (DDM)
The Digital Display Module (DDM) is an eight-character display that can be
attached to sensors to provide a local digital reading. Once the display is
added to the network and assigned to the sensor by the Master AquaTrend
Interface, it will automatically display data from the sensor. For sensors that
have multiple parameters (measurements), you can choose which parameter
you want to display on the DDM. See the
detailed information.
2.2.9 Repeater Module
The AquaTrend Repeater module is a physical layer repeater used to extend
the length of the AquaTrend Network by a maximum of 500 meters. A total of
three such devices can be installed on the AquaTrend Network to extend the
total length of the network to 2000 meters.

Section 3 Initial AquaTren d Setup
3.1 Identifying the Master AquaTrend
Every AquaT rend® Interface Network System requires a network manager
to perform network operations, such as adding or removing devices.
The AquaTrend and AquaTrend with SOM can perform network
management functions when set to Master AquaTrend status through the
AquaTrend software; however, only one Master AquaT rend can be present on
the network at a time. All other AquaTrends must be set to Remote AquaT rend
status. Care should be taken when determining the location of the
Master AquaTrend Interface.
Every AquaT rend Interface is shipped in an undefined state. When connecting
only one AquaTrend Interface to the network, it must be designated as the
Master AquaTrend Interface.
Set the system AquaTrend Interface to Master status as follows:
1. Upon initial power-up, select MASTER and press the ENTER key.
2. Press Enter to select Network Manager to ON. After a brief delay, the
display will show the data display screen (CHANNEL NOT ASSIGNED).
3. Press the Menu key to proceed to the Main Menu.
3.1.1 Adding Remote AquaTrend Interfaces to the Network
Upon power up, new AquaTrend Interfaces on the network will search for a
Master AquaTrend Interface. (The exception is when installing an AquaTrend
Interface that has previously been installed as part of another AquaTrend
network. In this case, the AquaTrend that is new to this network will not
automatically check for a master. To force it to check, press the EXIT key
when instructed to install the remote from the network manager.)
Once a master is identified, the additional AquaTrend Interfaces will assume
remote AquaT rend Interface status and can be added to the network using the
instructions in section 3.4.2, Adding a Device to the Network.
The Master AquaTrend Interface should not be changed to a remote unless
you want to change the location where network operations are performed.
A change from Master to Remote AquaTrend Interface status will erase all
network information, requiring you to restore network connections.
