6712SR Refrigerated Sampler

Section 1 Introduction

The 6712SR Refrigerated Sampler is an integral part of Teledyne Isco’s comprehensive sampling system. The system includes the 6712SR and 6712SR Refrigerated Samplers, the 6712 Compact Sampler, and the 6712 Standard Sampler.
The 6712SR is ideally suited for permanent installation in a wide variety of indoor and outdoor environments. Constructed from durable, corrosion resistant materials, the 6712SR withstands the hostile environments of industrial and municipal monitoring sites. However, do not install in locations where the refrigerator’s lower compartment could become submerged.
The 6712SR accepts a variety of sequential and composite bottle kits. Like all samplers in the 6712 series, it is compatible with a variety of Teledyne Isco instruments.

1.1 About This Manual This manual contains the information you will need to install,

program, operate, and maintain a 6712SR refrigerated sampler. There are eight sections and five appendices:
Section 1, Introduction lists the features and specifica- tions of the 6712SR refrigerated sampler.
Section 2, Installation/Preparation steps you through installing the sampler and preparing it for use.
Section 3, Getting Started describes features that are common to both standard and extended programming modes.
Section 4, Standard Programming shows how to program your sampler using standard programming mode.
Section 5, Extended Programming shows how to program your sampler using extended programming mode.
Section 6, SDI-12 Sondes provides information on setting up sondes to work with the 6712SR.
Section 7, Remote Operation explains how the 6712 controller can be operated remotely from external devices.
Section 8, Maintenance covers the basic maintenance required to keep your sampler in top operating condition.

• Appendix B, Material Safety Data Sheets
• Appendix C, General Safety Procedures
• Appendix D, Replacement Parts
• Appendix E, Accessories List

1.2 About 700 Series Modules

The bay on the controller’s side accepts any of Teledyne Isco’s 700 Series Modules. The 700 Series includes:
• 701 pH Parameter Module for monitoring pH and temperature.
• 710 Ultrasonic Module for monitoring a flow stream’s level and flow rate with an ultrasonic level sensor.
• 720 Submerged Probe Module for monitoring a flow stream’s level and flow rate with a submerged probe.
• 730 Bubbler Flow Module for monitoring a flow stream’s level and flow rate with a bubbler system.
• 750 Area Velocity Module for monitoring a flow stream’s level, velocity, and flow rate.
• 780 4-20mA Input Module for interfacing to non-Teledyne Isco devices with 4 to 20 milliampere output signals.
The modules are optional accessories, and are not required for operation. However, the modules offer a number of advantages: they are an economical way to combine flow-rate or parameter monitoring with sampling, and you can program the samplers and modules as a single unit. Finally, the samplers store the readings in memory.

1.3 SDI-12 Sondes As an option, the sampler accepts up to 16 parameters from up to

ten sensors with SDI-12 addresses from 0 - 9 (refer to SDI-12 Sonde Readings, page 1-10, for specific parameters).
The data parameters used by the sensing device (sonde) and recording device (sampler) must match. Certain vendors’ sondes have enhanced commands that facilitate “plug and play” setup. These Teledyne Isco Ready sondes can tell the 6712SR what values they have, their order, and units of measure. Other sondes can be used, but require manual setup to identify proper data types for each data value reported.

1.4 Memory to Store Monitoring Data

1-2
The samplers contain enough memory to store five sampling pro­grams, sampling data, Teledyne Isco 700 Series Module readings, and SDI-12 parameter readings. You can view the readings on your sampler’s display.
You can also retrieve the readings and reports so the information can be processed on a personal computer. Readings and reports may be collected with a computer running Teledyne Isco’s Flowlink™ software. Flowlink can download the information through a direct connection, a modem connection (when the
6712SR Refrigerated Sampler
Section 1 Introduction
sampler is equipped with the optional dial-out modem), or from a 581 Rapid Transfer Device (RTD). The RTD is a quick and simple way to transfer the data from the field to your computer. Reports are easily collected with Teledyne Isco’s Samplink software.

1.5 Pump Requirements The pump requires a pump tube made specifically for the 6712

and 6700 Series samplers. These pump tubes are easily recog­nized by their blue alignment collars. The 6712 pump tubing is the same as that for Teledyne Isco’s 6700 Series samplers, but different from Teledyne Isco’s earlier model samplers, such as the 3700 Series. Other types of pump tubing will not work in the 6712SR. Refer to Replacing the Pump Tube on page 8-8.

6712SR Refrigerated Sampler

Section 2 Installation/Preparation

2.1 Preparing the Sampler The 6712SR is shipped to you with the controller mounted on the

refrigerator and a distributor shaft extension installed. Use Figure 2-1 for reference when removing the controller. You must remove the controller when:
• The internal desiccant needs recharging, the internal battery needs to be replaced or when the controller needs repair.
• You install a different bottle kit.
Each bottle kit has its own extension so that the distributor arm is positioned at the right distance above the bottles. You must remove the controller to replace the extension.

2.1.1 Installing the Distributor Shaft Extension

2.1.2 Mounting the Controller

1. Install the extension before mounting the controller on the refrigerator.
2. Select the extension of the correct length for the bottle kit, and screw it on the distributor shaft. Secure it with the set screw. See Figure 2-1.
BE SURE THE SET SCREW IS TIGHTENED INTO THE DISTRIBUTOR SHAFT’S KEY. YOU MAY HAVE TO LOOSEN THE EXTENSION SLIGHTLY AND ADJUST ITS POSITION.
1. Install the four mounting rods into the bosses on the bot­tom of the case.
2. Fit the mounting rods through the four holes drilled in the top of the refrigerator.
3. Slip a washer on each rod and secure the controller by tightening the wing nuts.
4. Install the distributor arm and discharge tube.
5. Thread the stop arm into the hole in the side of the exten­sion. Be sure the stop arm is directly above the distributor arm.
6. Connect the power cable to the controller.

2.1.3 Installing the Distributor Arm and Discharge Tube

Distributor Arm
The distributor arm is adjustable so that you can position the discharge tube over the bottles of each kit. Each bottle kit also uses a discharge tube of a specific length. Table 2-1 lists the correct discharge tube lengths for each bottle kit. If you are using bulk tubing to cut your own tubes, cut the ends of the tube square, not at an angle, and cut the length accurately.
The two-piece distributor arm has four positions, marked on the underside with the letters A, B, C, and D. Adjust the arm to the correct position for the bottle kit being used. Table 2-1 shows the correct position for each kit. Thread the discharge tube through the spring and arm so that the tube protrudes from the arm
1
/16
to 1/8 inch. If too much tube protrudes from the arm it can catch on bottles and jam the distributor arm.
Attach the arm to the distributor shaft extension. Secure the arm to the extension with the black plastic nut. Slide the free end of the discharge tube onto the bulkhead fitting. After installing the distributor arm and discharge tube, run the distributor to each bottle position to ensure proper installation.
