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.

1.5 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

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.

4.1 Alarm to Relay Connections

Sensors allow you to set up a number of alarms for various conditions. If a
sensor measurement is attached to a channel on the AquaTrend
and an alarm is activated on that sensor, a number appears at the bottom of
the display. That number corresponds to the channel with the active alarm
(see number 4 in Table 5 on page 14).

After setting up the sensor alarm parameters as specified in the sensor
manual(s), the next step is to attach the alarm signals to an electrical relay in
a Signal Output Module (SOM). The AquaT rend Interface system allows you
to attach one alarm from a sensor to one relay on any SOM on the network.
See section 4.1.1 and section 4.1.2 below.

Each SOM (stand-alone unit or built into the AquaTrend Interface) provides
two analog outputs and two relays to the network. As many as eight SOMs
can be added to the network.

5.5 Interconnecting other Devices on the Network

If all of the available access holes and/or wiring terminals in a PS1201 or
sensor’s power supply have been used, preventing the connection of other
new devices into the AquaTrend Interface network system, it may be possible
to use an existing device (AquaTrend Interface or Signal Output Module) to
provide network and/or power connections for a new device.

Before connecting a new device to an existing device instead of directly to a
PS1201 consider the following questions:

1. Is the total power consumed by the existing devices, plus the new device,
within the capabilities of a single PS1201? (Refer to the PS1201 manual
for instructions on calculating this.) Failure to confirm this could result in
failure of the existing PS1201 due to thermal overload. Such failure is
NOT covered by warranty.

2. Is there an unused knockout on the existing device, so that the new
connections can be made while preserving network integrity?

If the answers to BOTH of the above questions are yes:

The new device can be connected to an existing device using its existing
PS1201. To connect both power and network signals to the new device via an
existing device, proceed as follows:

Section 5

1. Procure the required length of 4-conductor, shielded cable

(Cat. No. 52158) to make both the power and network connections.

2. Route the cable in accordance with local building codes. Remove AC
input power from the PS1201 that supplies power to all of the devices
involved.

3. Strip approximately six inches of insulation from the 4-conductor cable.

4. Insulate the shield using Cat. No. 40825-00 heat-shrink tubing.

5. Remove about ½ inch of insulation from each of the remaining wires.

6. Remove, one at a time, each wire from the terminal block of the existing

device. Match that wire with the same color wire from the new device.

7. Twist the ends of the two wires together and insert them both into the
terminal block position where the original wire originated.

8. Connect the other end of the new cable to the new device, following the
instructions in the manual supplied with that device.

9. After all connections have been verified, reapply input AC power to the
PS1201, and follow the instructions in the new device’s manual for
configuring the new device to function on the network.

If the answer to question 1 was no, but the answer to question 2 was yes:

Connect only the cable which sends network signals from the existing device
to the new device. Connect the new device power connections to an additional
PS1201 or sensor power supply. Follow the instructions in the PS1201 or
sensor manual.

Page 69

51350-18 Hardware Installation.fm Interconnecting other Devices on the Network

Section 5

To connect AC power to the new device, proceed as follows:

1. Procure the length of 4-conductor, shielded cable (Cat. No. 52158)

needed between the new power supply and the new device.

2. Using a Cable Termination Kit (Cat. No. 52156-00), install this cable
between the new power supply and the new device in accordance with
their respective manuals.

To connect the network signals to the new device from the existing de vice, proceed as follows:

1. Determine the length of cable needed between the new device and the

existing device which will provide network signals. Procure this length of
2-conductor, shielded cable (Cat. No. 52157) plus a Cable T ermination Kit
(Cat. No. 52156-00).

2. Route the 52157 cable in accordance with local building codes, and
proceed as follows to connect one end of this cable at the existing device:

a. Remove input AC power from the PS1201 or sensor that is powering

the existing device.

b. Connect the white and green wires in the new cable to the correct

terminals in the existing device, if the device has the white and green
wires. Refer to the existing device’s manual for which terminals get
which color wire.

IMPORTANT NOTE: DO NOT connect the shield of the new cable to any
terminal in the existing device. It must only be connected at the new device.

3. Connect the other end of the 52157 cable to the new device as follows:
a. Refer to the new device’s manual for proper terminal connections.

b. Connect the white and green wires to the correct terminals in the

new device.

c. Insulate the shield using the tubing supplied in the Cable Termination

Kit, then connect it to the appropriate terminal in the new device.

After all connections have been verified, apply input AC power to both the
existing and new PS1201, and follow the instructions in the new device’s
manual for configuring the new device to function on the network.

Appendix A Use of Subnets

The AquaTrend system allows multiple AquaTrend systems to communicate
on one set of network wires. The largest advantage to installing multiple
systems on one set of network wires is the need for fewer wires (particularly
for long wire runs between the sensors and the control room). The number of
systems which can be installed on one set of wires is installation dependent,
but typically is limited to 5-6 systems. Contact Hach Customer Service for
specific applications.

Note: An AquaTrend system is
defined as 1 Master AquaTrend and
up to 8 sensors , 8 SOMs , 8 DDMs , 8
Remote AquaTrends, and 2 SIOs.

When multiple systems are installed on a single set of network wires, each
system (and each device within that system) must have a subnet address
assigned to it. The instructions below explain how to change the subnet.

Changing the Subnet Address

1. Start with all of the devices unconfigured.

2. Select the AquaTrend that is to be the Master for the first system. Install

this AquaTrend as a Master (see section 3.1 on page 23).

3. From the Network Menu choose SELECT SUBNET.

Note: This entry will only appear if there have not been any devices added by this

AquaTrend.

4. Change the subnet number (2-9) to an unused number and
press ENTER.

Note: Record this subnet number to avoid installing an additional Master AquaTrend

on the same subnet.

5. Install other devices (sensor, etc.) on this AquaTrend system in the usual
way (see section 3.4.2 on page 26).

6. Repeat this procedure for additional AquaTrend systems.

Glossary

AquaTrend Network System - A system which provides a digital interface

link between sensors and communication devices and can receive data from
these devices at a maximum distance of up to 500 meters (1640 feet.). The
fieldbus communications that makes such configuration possible is provided
by Echelon

The network software may configure up to 35 devices including: one
Master AquaTrend, as many as two Serial I/O Modules, and up to eight
sensors, eight Signal Output Modules, eight Digital Display Modules, and
eight Remote AquaTrends.

channel - Where data is displayed and logged on the AquaTrend. The
AquaTrend has eight channels (represented by the letters A through H) to
which you can attach measurements from sensors.

configure - Setting up a Hach network device for operation after hardware
installation is complete. This involves selecting various software options and
establishing communications between devices.

device - Any of the Hach network instruments, including sensors,
communications modules, display modules, outputs, and AquaTrends.

®

LonWorks® technology.

Digital Display Module (DDM) - An eight-character display that can be used
with sensors or analyzers to display a single measurement. It can be mounted
as far away as 400 meters (1310 feet) from the sensor.

Echelon

®

technology - communications technology used by the AquaTrend
Network System and developed by Echelon Corporation, producers of
LonWorks

®

fieldbus technology.

fieldbus - Any of several techniques allowing multiple devices to be
connected on a single set of wires.

LonWorks - The fieldbus protocol used by the AquaTrend Network System.
Master AquaTrend - Acts as the main network data control center for setup

and operation of the network. The network can contain as many as nine
AquaTrends but only one can be the Master AquaTrend. Only through the
Master AquaTrend can you perform network operations.

network - The connection of one or more devices (of which at least one is a
sensor or analyzer) to a Master AquaTrend.

pop-up box - Refers to a selection or message box at the end of a menu
chain. This box either provides a choice of options, selectable by moving the
cursor and pressing ENTER, or allows you to use the arrow keys to enter an
alphanumeric response, or it states the status of the current operation. These
three possibilities are respectively shown below.

Portable AquaTrend - Mobile device designed to setup and calibrate sensors

already setup on the network. Portable AquaTrends can access all menus
except the network menu and can not perform network operations.

PS1201 - A power supply that provides 25 watts to AquaTrend
network devices.

Remote AquaTrend - Any AquaTrend on a network that is not a Portable or
Master AquaTrend. Remote AquaTrends can display all sensor readings and
access all sensor menus.

repeater - A device capable of amplifying signals when total cable distance is
exceeded in order to extend the network’s capabilities.

SCADA - Supervisory Control and Data Acquisition. General term for any
automated (and usually PLC or computer-controlled) system for control and
data acquisition.

sensor - Any one of the Hach devices designed to take measurements for
specific parameters and for use with the AquaTrend Network System
(

e.g.

the 1720D Turbidimeter)

Serial I/O Module (SIO) - Communication device for two-way communication
with a PC or one-way communication with a printer.

Signal Input Module (SIM) - The Signal Input Module (SIM) provides two
4-20mA analog inputs which can be used to bring measurements from
non-networked sensors into the network.

Signal Output Module (SOM) - Network device that 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
keypad at either 4-20 or 0-20 mA. Sensor alarms can be configured to trigger
one the relays in the SOM and/or a recorder or controller signal from a sensor
can be attached to the analog outputs of the SOM.

The SOM can either be a stand-alone device (model 51250) or can be internal
to the AquaTrend/SOM (model 51350).

terminator - Impedance stabilizing component that maintains network signal
integrity. One terminator is required for proper network operation, either on an
AquaTrend (without SOM) or on a stand-alone SOM.

topology - Any wiring configuration. See Figure 26 for examples.

and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user
will be required to correct the interference at his own expense.

The following techniques of reducing the interference problems are
easily applied:

1. Disconnect the AquaTrend Interface from its power source to verify that it

is or is not the source of the interference.

2. If the AC power supply for the AquaTrend Interface is connected into the
same outlet as the device with which it is interfering, try another outlet.

3. Move the AquaTrend Interface away from the device receiving the
interference.

4. Reposition the receiving antenna for the device receiving the interference.

5. Try combinations of the above.
