Section 1 Basic System Information

An AquaTrend® Network System uses a single AquaTrend Module to interface a variety of instruments. The network is built by wiring a sensor, power supply, and any other peripheral device with LonWorks® digital Network capabilities or 4–20 mA network capability using the signal Input Module and establishing communications via the AquaTrend Interface. Power and network connections are required for all AquaTrend devices operating on the network.

After physically installing the devices, you must add each device to the AquaTrend network via the network menus in the Master AquaTrend. 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, you must instruct the sensor to attach its reading to a designated AquaTrend 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 Network System.

1.1 How To Use This ManualThis manual is intended to be used as a quick-start guide to efficiently get your system up and running. The instructions for installing the basic components of a single or two sensor system are presented in the main body of the manual with the instructions for optional accessory devices presented in the appendices. It is written to be followed sequentially, enabling all the tasks to be performed in the most efficient order.

Please take the time to familiarize yourself with the manuals supplied with the individual devices that comprise your system. Important safety information, additional detail on the tasks outlined in this manual, and other more advanced features are presented in the specific device manuals. Figure 1 illustrates the major steps for installing the system. Figure 2 shows the components of a basic Single Sensor System.

AquaTrend

• 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 network operations be performed.

• Remote AquaTrend — Any AquaTrend on a network that is not a Portable or Master AquaTrend. Remote AquaTrends can control and monitor all sensors on the network. Remote AquaTrends cannot perform network operations.

• Portable AquaTrend — Mobile device designed for set up and calibration of sensors already on the network. Portable AquaTrends can communicate with one sensor at a time and cannot perform network operations.

3.2 Power Supply to Power Supply Network Interconnect

Note: The steps that follow must be duplicated for each power supply. The only exception is the connection of the shield. When power supplies are connected in a series of two or more, the shield is connected at only one end for each pair of power supplies.

Each turbidimeter must have a PS1201 to provide ac power. The power supplies may be interconnected via a two conductor, shielded cable with a length less than 400 meters. Although these types of connections are usually made between two PS1201 Power Supplies, information for interconnecting between other modules is presented in the instruction manuals for those modules.

For connections between two Power Supplies, refer to Figure 20 and proceed as follows:

Figure 20 Power Supply Interconnect Wiring

1. Make sure no power is being supplied to either PS1201 Power Supply.

2. Unscrew the four screws securing each PS1201 face using a flat-bladed screwdriver.

3. Lift the faces off both of the Power Supplies and set them aside, or, store the front cover by screwing the right side of the front cover to the left side of the back enclosure.

4. If necessary, use a punch and hammer (from the outside of the enclosure) to remove one of the left three unused knock-outs on the bottom of each PS1201 enclosure. Center the punch on the knock-out for best results.

Power Supply to Power Supply Network Interconnect 52004-88 wiring the devices.fm

Section 3

5. Route the interconnect cable (Cat. No. 52157) to each PS1201 enclosure through the holes created in Step 4, using the strain relief fittings provided. Make sure the outer cable insulation is just captured by the strain relief fitting.


7. Strip ¼-inch of insulation from each wire and insulate the shield wire with appropriate tubing. Insulate the non-connected end of the shield wire with electrical tape.

8. Connect the ends of the cable as shown in Table 8. See Figure 20 on page 32.

Note: Connect the shield only at one end of the interconnect cable (choose either end). Insulate the non-connected end with tape or heat-shrink tubing.




11. Ensure the gaskets are properly seated and replace the faces on both power supplies. Replace the corner screws and tighten to 10 in-lb (1.1 n-m) maximum to maintain the NEMA rating.

3.3 Other Device WiringWiring information for the Serial Input/Output (SIO) Module is presented in Section 9.1 on page 53 or in the SIO Manual (Cat. No. 52074-18).

3.4 Network Termination

Note: To avoid damaging the instrument, remove power to the instrument before removing the front cover.

The network signals require a terminator for proper operation. As shipped from the factory, the terminator is disabled on all devices.

Important Note: Failure to properly terminate the network may cause total network failure. Only one device must have the network terminator enabled.

3.4.1 Network Termination at the AquaTrend/SOM or the SOM

1. Identify the AquaTrend/SOM or SOM the network termination will be performed on.

2. Remove the front face of the AquaTrend/SOM or SOM and locate J4 (a white, three-pin connector shown in Figure 21) on the circuit board in the back enclosure of the device. A jumper connected only to pin 2 should be present as shown in Figure 22.

3. To enable the terminator, lift the jumper off of pin 2 and move the jumper so that it connects pins 2 and 3 as shown in Figure 21.

4. Make sure all cable strain reliefs are tightened properly and replace the front panel.

Section 4 Plumbing the Turbidimeter

4.1 Hydraulic ConnectionsSample inlet and drain connections are made on the turbidimeter body. The sample inlet fitting installed in the body is a ¼-inch NPT x ¼-inch compression fitting. One additional fitting supplied with the instrument is a ½-inch NPT-to-hose fitting for use with ½-inch ID flexible plastic tubing on the drain.

Figure 24 Sample Flow

One-fourth inch OD rigid or semirigid tubing is recommended for sample lines. Run them as directly as possible between the turbidimeter body and the sampling point to minimize sample flow lag time.

The optimum flow rate is 250-750 mL/minute (4.0 to 11.9 gal/hour). Flow rate into the turbidimeter may be controlled with a flow restriction device on the inlet line. Flow rates below 250 mL/min. will reduce response time and cause inaccurate readings. Flow rates above 750 mL/min. will cause the turbidimeter to overflow into the drain. Inaccurate readings may be seen if the flow rate is too high.

4.2 Starting Sample FlowStart sample flow through the instrument by opening the sample supply valve. Allow the turbidimeter to run long enough for the tubing and body to become completely wetted and the reading on the display to stabilize. One to two hours may be required initially for complete stabilization.

Section 5 Power and Startup of the System

5.1 AC Input Power Please refer to the PS1201 Power Supply Manual for all necessary information for wiring the PS1201 Power Supply to AC power.

When all network and AC wire connections have been completed, make sure all modules are closed and enclosure gaskets and covers are securely in place to maintain the NEMA rating on the equipment. Supply sample to the turbidimeter and initially allow it to flush the turbidimeter body for one to two hours. Supply power to all PS1201 Power Supplies. Check the status of all modules and sensors. If the module or sensor has an external configure light, the light should be flashing. (The configure light is internal to the Signal Output Module (SOM) and AquaTrend with SOM.) The configure light on each module and sensor will be extinguished when the modules are configured by the software.
