2.2 Network SetupThe network setup consists of three steps:

1. Adding the Digital Display Module to the AquaTrend Network (Section 2.2.1).

2. Assigning the Digital Display Module to a sensor (Section 2.2.2).

3. If necessary, assigning a sensor measurement to the Digital Display Module (Section 2.2.3).

The Digital Display Module must be added to the AquaTrend Network before the AquaTrend Network can recognize and route data to the module. After the module is added, it must be assigned to a particular sensor and, in the case of multi-parameter sensors, assigned a parameter (measurement) from that sensor.

The following illustrations show the menu path required to configure the Digital Display Module using the AquaTrend Interface.

Note: If the Digital Display Module has just been added to the network and its yellow LED does not flash when first plugged in, the module must be unconfigured (see Section 3.2.3).

The yellow LED on the front of the Digital Display Module flashes when the module is initially plugged in to indicate the module is not configured. After the module is configured by the AquaTrend, the yellow LED turns off. (The light only shines steadily while the CONFIGURE button is being pushed.)

If the yellow LED does not flash when the Digital Display Module is plugged in, the AquaTrend Interface will not be able to configure it. Unconfigure the

Page 1952400S2.FRM Network Setup

Section 2

module as in Section 3.2.3. (See the same section for a discussion of the configured vs. the unconfigured state.)

If, during the following procedures, the AquaTrend Interface reports that no Digital Display Modules are found on the network, check the physical connection between the module and the sensor and repeat the procedure.

Figure 8 shows the display window of the AquaTrend Interface Module with menu keys and screen.

4. Select the category DISPLAY. Press ENTER.

5. The AquaTrend Interface will list the available, configured Digital Display Modules. Select the module you wish to remove. Press ENTER.

6. The AquaTrend Interface will ask for confirmation. Press ENTER.

2.3.2 Replacing the Digital Display ModuleUse this procedure when you want to transfer the settings of one Digital Display Module to another. This procedure works best if both modules are physically connected to the network. If not, use the REMOVE DEVICE procedure to remove the current Digital Display Module, then physically unplug it from the network and use the ADD DEVICE to add the new module (after physically plugging it into the network). If the first module already has been physically unplugged from the network, and the REMOVE DEVICE procedure was not used, it will need to be unconfigured before it can be used again (see Section 3.2.3, Unconfiguring the Digital Display Module, on page 28).

This option will take you through all the steps necessary for completely removing the Digital Display Module and adding a new module—with the settings and sensor assignment of the original module—to the network as in sections 2.2.1, Adding the Digital Display Module to the Network, on page 20 and 2.2.2, Assigning the Digital Display Module to a Sensor, on page 22.



3. Select REPLACE DEVICE. Press ENTER. The AquaTrend Interfacewill prompt you as necessary.

2.3.3 Detaching the Digital Display Module from a Sensor

Note: The REMOVE DEVICE procedure (Section 2.3.1) automatically detaches the Digital Display Module.



3. Select SENSOR TO DDM. Press ENTER.

4. Select DETACH, press ENTER and follow the AquaTrend’s prompts.

5. If two or more Digital Display Modules exist on the network, the AquaTrend will list each with its location. Select the module you wish to detach and press ENTER.

To assign the display to a new sensor, follow the procedure for attaching the Digital Display Module to a sensor in Section 2.2.2.

2.3.4 Editing the Display NameThe display name of each Digital Display Module may be changed at any time:


2. Select OTHER DEVICE MENU. Press ENTER.

3. Select DISPLAY MODULE. Press ENTER.

4. The AquaTrend will list all available Digital Display Modules. Select the DDM of interest. Press ENTER.

5. Press ENTER to select EDIT NAME.

6. Use the arrow keys (right or left arrows to move to another character space in the name and the up or down arrows to scroll through the available characters) to create a unique device name (up to 12 characters). Press ENTER to accept the name.

Note: To distinguish between devices on the network, create a unique and descriptive name consisting of up to 12 characters.

Section 3 Maintenance and Troubleshooting

3.1 MaintenanceThe Digital Display Module is watertight and needs little maintenance. Use warm water and soap to clean the outside; avoid harsh solvents.

3.2 TroubleshootingThe Digital Display Module contains built-in diagnostics and a self test to assist with problems.

3.2.1 Configure LEDThe configure LED provides information about the state of the Digital Display Module. When powering up the module, the configure LED lights for a half second to indicate the LED is working properly. The configure LED also lights when the CONFIGURE button is pressed.

The following table describes the state of the device after power up and assumes the CONFIGURE button is not being held down.

3.2.2 Power-On Display TestThe power-on display test is started automatically after powering up a configured Digital Display Module (the test will not run if the device is unconfigured). During this test, each segment of the LED display is lighted to ensure no segments are defective. Each of eight messages are displayed for approximately 1 second, sequentially:

If a segment fails to light during the power-on display test, call Hach Service.

Section 3

3.2.3 Unconfiguring the Digital Display ModuleUse this procedure only if the AquaTrend Interface will not remove the Digital Display Module in Sections 2.3.1 Removing the Digital Display Module on page 23 or 2.3.2 Replacing the Digital Display Module on page 24.

Restore the factory defaults in the Digital Display Module (and erase all network-applied parameters) with the following procedure:

1. Unplug the Digital Display Module from the sensor or network.

2. Press and hold the CONFIGURE button on the module.

3. While holding the CONFIGURE button in, plug in the module again.

4. Release the CONFIGURE button after ten seconds.

The Digital Display Module is now ready to be added to the AquaTrend network with the ADD DEVICE procedure in Section 2.2.1.

3.2.3.1 Configured vs. Unconfigured StateDevices on the AquaTrend Network can be in three different “states”:

• Unconfigured devices have no network information stored in their memory. They can only respond to a network manager such as the AquaTrend Interface as unconfigured devices.

• Configured devices have been assigned a name and address by the AquaTrend network and respond to the system as configured devices. Device settings are recorded in the AquaTrend Interfaces’s network management database and in the device’s memory.

These settings must be erased in both the network management database and the device memory if the device is to be re-configured at any time. Normally, the AquaTrend Interface will take care of this when performing network functions such as REPLACE DEVICE or REMOVE DEVICE. If the device, however, is physically unplugged from the network before it is unconfigured by the AquaTrend Interface, it will retain certain settings in its memory.

If the device is physically re-connected to the same network, it will immediately function as it was originally setup. If, however, the REPLACE DEVICE or REMOVE DEVICE procedure is used to remove or replace the device while it is unplugged, the AquaTrend Interface will remove that device from the network management database and will no longer treat the device as a functioning (configured) device on the network if the device is plugged in again.

Also, when that same device is plugged back into the network, it will not respond to the AquaTrend Interface as an unconfigured device because of the device settings still resident in its memory. The AquaTrend Interface can only perform the add device or similar procedures on unconfigured devices.

Devices that are physically removed from the network before being unconfigured by the REPLACE DEVICE or REMOVE DEVICE procedure must be unconfigured (see Section 3.2.3) before being used on any network again.

• Attached devices are configured devices that have been assigned tasks. They receive and send data.

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® LonWorks® technology.

The network software may configure up to 35 devices including: one Master AquaTrend Interface, 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 Interface. The AquaTrend Interface 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 AquaTrend Interfaces.

Digital Display Module (DDM) - An eight-character display device 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 and 30.5 meters (100 feet) from a PS1201 power supply.

Echelon® technology - communications technology used by the AquaTrend Network System and developed by Echelon Corporation, producer 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 Interface. Only through the Master AquaTrend Interface 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 Interface.
