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.

6712 Front Panel

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.

The appendices are:

• Appendix A, Menu Flowcharts

• 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

/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.

6712SR Refrigerated Sampler Section 2 Installation/Preparation

2.2 Installing Bottle Kits Teledyne Isco ships the refrigerator from the factory with the

sample bottles in place. When using the sampler for the first time, you will only need to remove the bottle lids. When installing cleaned bottles or a new kit, keep these guidelines in mind:

• Do not mix glass and plastic bottles together.

• Install all bottles to insure that they remain in place.

• Align the racks correctly. If the racks are misaligned, the sampler may miss the bottle mouth, or the sampler will deposit samples in the “wrong” bottle.

Each time you change from one size bottle to another, you must adjust the length of the distributor arm, install a discharge tube of the correct length, and possibly install a different distributor shaft extension.

Each time you install a bottle kit, check the program settings for the number of bottles and bottle volumes. Also rotate the distributor arm to each bottle position to ensure the arm is correctly positioned over each bottle. Use the controller to move the arm.

2.2.1 Installing Racks Install the bottle rack with bottles by sliding it into the cooling compartment until the rack drops over the two semicircular ramps which hold it in place (Figure 2-2).

The five posts and two ramps which position the rack under the distributor arm are adjusted at the factory. When you change bottle kits, you may need to readjust the stops and ramps and install a different distributor arm extension. Figures 2-3 and 2-4 show you how to install the bottle kits.

Check the kit’s alignment by rotating the distributor arm. Do

not rotate the distributor manually. Moving the arm manually damages the distributor drive. If you see any mis-

alignment, adjust the posts and ramps until the discharge tube at the end of the arm stops over each bottle.

Next, adjust the distributor arm to position D for the 12-bottle and 24-bottle kits, or to position B for the 8-bottle kit. Install the arm and stop. See Installing the Distributor Arm and Discharge Tube on page 2-2.

Slide the rack, with bottles installed onto the mounting plate. Adjust the stops and ramps on the plate so that the rack is centered and held firmly on the plate.

Finally, position the arm over each bottle. If the arm does not stop over each bottle, readjust the rack.

Install over the mounting plate at the bottom of the refrigerator, the locating base which holds the 2 lon polyethylene bottles.

Begin by loosening the ramps. Move them toward the front of the compartment so that they will fit under the ridge of the locating base. (You can also remove them completely.)

Remove the two front stops, and align the holes on the sides of the locating base with the holes for the stops in the mounting plate. Secure the base by replacing the stops.

Install the bottles, and position the arm over each bottle.

2.2.2 Removing Racks Before removing the rack, place the lids on the bottles so the samples do not spill. Remove the bottle rack by lifting the front edge of the rack slightly to disengage it from the two ramps. Then, pull it straight out of the refrigerator. Be careful not to catch the distributor arm against the bottles.

2.2.3 Installing Composite

Bottles

Remove the distributor arm and discharge tube. Remove the distributor arm stop. If using the two bottle locating base, remove it.

Slide the composite bottle discharge tube on the bulkhead fitting.

Composite bottle kits have two lids, one with a hole drilled in the center. Screw the lid with the hole in it on the bottle, and place the bottle in the center of the mounting plate.

Thread the discharge tube through the hole in the lid. Always use the lid to retain the discharge tube. It prevents the sampler from spraying liquid inside the sample compartment instead of the bottle.

6712SR Refrigerated Sampler

Section 2 Installation/Preparation

2.3 Suction Line The suction line is the tubing from the sampling point to the

pump intake. The 6712SR uses a

/8-inch ID suction line of

lengths 3 to 99 feet. Teledyne Isco offers vinyl or Teflon® suction lines. The Teflon® tubing has a polyethylene jacket to protect it from kinks and abrasions.

The vinyl line contains a very low parts-per-million level of phenols. If phenol content affects your sample analysis, use the Teflon suction line.

When installing the sampler, be sure the vertical distance between the liquid level and the pump is as small as possible.

2.3.1 Guidelines for

Measuring and Cutting the Suction Line

• Cut the line to the desired length but use the shortest length feasible for the installation.

• Cut the line in 1 foot increments. For instance, 4 feet,

/2. If using metric units of measure, cut the line in

not 3 increments of 0.1 meter. Do not include the length of the strainer in the measurement.

2.3.2 Attaching Suction Line to Pump Tube

Attach the vinyl suction line to the pump tube with the tube coupling. Use the black clamp for the pump tube and the white clamp for the suction line. Attach the line and tube to the coupling by pushing them onto each end of the coupling. Then tighten the clamps by squeezing the finger pads together. Loosen a clamp by twisting it until its teeth disengage.

Attaching Suction Line Tube Coupling

Attach the Teflon® suction line to the pump tube by inserting the line into the tube and secure with a suitable clamp.

2.4 Strainers Teledyne Isco offers three styles of strainer that help prevent

solids from clogging the suction line:

•

/8-inch standard weighted polypropylene strainer for

routine and priority pollutant sampling

•

/8-inch stainless steel low flow strainer

• Weighted, CPVC-coated strainer for acidic liquid sources

To select the right strainer for your application, see Table 2-2. To install the optional low flow strainer in Teflon suction line, heat the end of the suction line to make it more pliable, then carefully screw the strainer’s threaded connector into the suction line.

2.4.1 Alternative to Strainers When sampling from high velocity streams with heavy sus-

pended solids, some field investigations suggest that more representative samples are obtained without the strainer. Consider attaching a short piece of thin walled aluminum tubing to the end of the suction line; anchor the tubing so that the inlet opens upstream. The aluminum tubing’s thin wall will not disturb the flow stream, and most sample analyses disregard aluminum ions. Under most conditions, the pre-sample purge removes any debris over the tubing entrance.

2.5 How Does the Sampler Work?

When the sampler takes a sample, it draws liquid through the strainer and suction line to the pump tube. The liquid flows through the pump tube and past the liquid detector, which senses the liquid. From the detector, the liquid follows the pump tube through the pump to the bulkhead fitting and then through the discharge tube to the sample bottle.

A typical sampling cycle consists of:

1. The sampler moves the distributor arm over the bottle that

2. The pump reverses for the pre-sample purge.

3. The pump direction changes, filling the suction line.

4. When the detector senses liquid, the sampler begins mea-

5. After depositing the sample, the pump again reverses for

Sampling cycles vary somewhat according to program settings for distribution. The sampler can move the distributor arm clockwise and counterclockwise, making a number of distribution methods possible. (In this manual, the words “sample event” refer to a full sampling cycle for any distribution.)

6712SR Refrigerated Sampler

Section 2 Installation/Preparation

Figure 2-5 Identifying the Sampler Components

Other variations include extended-program settings for suction-line rinses and sampling retries. A sampler running a program with line rinses completes the pre-sample purge and then rinses the line. The suction line is purged after each rinse. When programmed for sampling retries, the sampler will attempt to pump a sample again if it fails on previous attempts.

2.5.1 Measuring Sample Volume

“Sample volume” refers to the amount of liquid delivered into a bottle. The volume is determined by the programmed value. The volume is dependent on the volume per revolution of the pump, which is dependent on the suction head. The 6712SR delivers the sample by counting the pump revolutions and automatically compensating for the suction head.

2-9

6712SR Refrigerated Sampler Section 2 Installation/Preparation

2.6 Installing the Sampler The following segment briefly describes initial sampler instal-

lation.

CAUTION

Tests indicate that the pump produces sound levels in excess of 85db at one meter. Prolonged exposure to this sound could result in hearing loss and requires the use of protective ear plugs.

CAUTION

When using the 6712SR sampler with a 750 or 710 module, transmitters such as cell phones or walkie talkies must not be operated within 3 meters of the sampler. If water level readings are fluctuating due to TV/radio station transmitter towers in the area, the sampler must be relocated.

WARNING

The 6712SR samplers have not been approved for use in hazardous locations as defined by the National Electrical Code.

WARNING

If you must enter a manhole or other dangerous location to install the sampler, observe standard safety precautions. Refer to Appendix C for a discussion of safety considerations.

2.6.1 Tips for Routing Suction Line

2.6.2 Intake Placement For representative samples, place the intake in the main current

2.6.3 Positioning a Sampler Place the refrigerator on a relatively flat, horizontal surface.

Route the line so that it runs continuously downhill from the sampler to the liquid source. This helps drain the line during pre-sample and post-sample purges. When the sampler is used in below freezing temperatures, there is a risk of the suction line being frozen. A suitably warm sampling source can usually prevent this, provided there are no loops in the suction line. Some situations may require more protective measures, such as insulation of the suction line, or heat tape. Thoroughly draining the suction line minimizes the possibility of frozen liquid clogging the line.

of the flow stream, not in an eddy or at the edge of flow. Placing an intake at the bottom may produce samples with excess heavy solids and no floating materials, while placement at the top may produce the opposite conditions.

Placing the refrigerator on a steep incline may cause the sample to miss the bottle mouth.

2-10

6712SR Refrigerated Sampler

Section 2 Installation/Preparation

When installing the sampler, be sure the vertical distance between the level of the liquid and the pump is as small as possible.

CAUTION

The refrigerator’s lower compartment is not watertight. Do not install in a location where the refrigerator’s lower compartment could become submerged.

2.7 Connecting External Instruments

2.7.1 Flow Meter

Flow Meter Connector Icon

The 6712SR sampler can be used in conjunction with several types of external instruments.

To connect the sampler to a teledyne Isco open-channel flow meter, 4100 series flow logger, 2100 series flow module, or 1640 Liquid Level Actuator, attach the sampler-to-flowmeter cable to the Flow Meter Connector. To connect the sampler to a closed-pipe flow meter, attach a teledyne Isco 4-20 mA Input Interface device to the sampler’s Flow Meter connector. Plug the line cord into an AC power outlet. Be sure it is connected to 120 volts AC (optional 230 volts AC). When using the sampler with an external instrument, remember these guidelines:

• Both the sampler and the flow instrument must be on and running a program.

• If using a flow meter, logger, or module for flow pacing, the sampler and the flow instrument must both run programs with flow pacing settings.

• If using a flow meter or flow logger for trigger pacing, the sampler must run a program with flow pacing settings, and the flow instrument must run a program with trigger pacing settings.

• When the sampler runs an event-paced program, it disregards pacing pulses from a flow meter or flow logger. However, the sampler continues to monitor for enable signals.

2.7.2 Rain Gauge Connector

Rain Gauge Connector Icon

Connect the rain gauge, SDI-12 Sonde, or Refrigerator Temperature Sensor connect cables to the nine-pin Rain Gauge Connector. When connecting a rain gauge and an SDI-12 Sonde, or rain gauge and a Refrigerator Temperature Sensor, use the appropriate Y-connect cable. See the Accessories appendix at the end of this manual.

2.8 Locking the Sampler The refrigerator is equipped with a lockable latch for the top

cover and a lockable catch for the door handle. To lock the refrigerator, use two padlocks, one for the top cover and one for the door.

2.9 Servicing the Sampler Servicing the sampler includes:

• Collecting the filled sample bottles and replacing them with clean bottles;

• Collecting the data recorded by the sampler during the program.

Samplers are usually serviced after they complete a sampling program. When working up a service schedule, you will need to estimate the program completion time. You should also be familiar with the program’s settings for the start time or if the sampler is programmed for continuous sampling.

Continuous sampling is controlled by the distribution setting entered at the “RUN CONTINUOUSLY?” screen. A “YES” response directs the sampler to reset the distribution sequence and continue the countdown to the next sample event. Appropriate service intervals will prevent overfilled bottles.

3.1 Initial Operation

Before programming the 6712SR, you should become familiar with its keys and how to use the screens.

The 6712SR Sampler has two sets of programming modes. The first mode, Standard Programming, lets you set up typical sampling programs easily and efficiently. The second mode, Extended Programming, lets you create sophisticated programs for complex sampling applications.

All of the sampling features available in standard programming mode are available in extended programming mode. However, extended programming provides many additional features.

Standard and extended programming features are explained in separate sections. This section focuses on some basic features that are common to both programming modes, such as using the menus and setting the clock.

Turn the sampler on by pressing the On/Off key. It is labeled with this icon: . The start-up screen appears first.

The sampler is programmed at the factory so that the standard programming screens appear when you first turn the sampler on. You can switch between programming modes by typing in a numerical command at the main menu:

• At the main menu type 6712.2 to show the extended programming screens.

• At the main menu type 6712.1 to show the standard programming screens.

6712SR Refrigerated Sampler Section 3 Getting Started

The sampler will continue to use the program mode you selected, even if the sampler is turned off and on again, until you manually switch to the other programming mode.

With the display backlight activated, the screen will glow for several seconds following your last keystroke.

If you press a key and the screen text does not change, it is probably because the keystroke turned the backlight on, instead of performing its function. Press the same key again.

3.5 Menu Screens: Site Descriptions and Program Names

The sampler has two text-entry menus, one for site description and another for an extended-program name. They work in the same way. A site description is commonly a number, address, or other short note that helps identify the monitoring site. Extended programming has a similar screen that lets you enter program names for stored programs.

The example to the lower left shows how to change the site description from FACTORY01 to SITE 29. Line 1 contains text between two quotation marks. Lines 2 and 3 contain the menu options — numbers, letters, and punctuation marks — used to spell out the description. In line 3, the space between the ampersand (&) and the double quotes (") is a space character. Line 4 contains two additional options:

• BACK-UP, an option that moves the cursor on the text line to the left one character.

• DONE, an option that tells the sampler to save the text.

The cursor is the blinking rectangle that identifies the current field. When the screen first appears, the cursor blinks on the first character of the text in line 1. The matching character in line 2 or 3 also blinks.

When you press ↵, the cursor on line 1 moves to the right one position, and, at the same time, the sampler blinks on the matching character on lines 2 or 3.

To change any character in the text line:

1. Press the left or right arrow until the replacement character on lines 2 or 3 blinks.

2. Press ↵. The replacement character will appear on the first line, and the cursor will move to the next character.

Repeat steps 1 and 2 until the text in the top line is complete.

3. Finish the entry by selecting DONE. Then, press ↵.

Some additional tips for using the text-entry menus:

• Hold an arrow key down for faster movement.

• If your description uses all ten spaces in the text line, the sampler automatically moves to the next screen as soon as you add the tenth character.

• You can enter numbers by pressing the number keys.

• Erase characters by replacing them with a space character.

• Select the BACK-UP option to move the cursor to the left.

• To leave the menu before completing the entry, press Stop. The sampler will display this menu:

•Press the Down-Right arrow until DONE blinks. Press

WARNING!

STANDARD BOTTLE

VOLUME EXCEEDED!

The 6712 does accept nonstandard volumes because you might use a nonstandard container occasionally. For a list of recommended volumes for Teledyne Isco bottles press the ? (Help) key at the “Bottle Volume Is” screen, or refer to the Technical Specifications.

The 6712 uses the bottle and sample-volume settings to determine the maximum number of samples that can be deposited without overfilling the bottles. Entering a volume that exceeds the standard volume may cause the sampler to overfill the bottle.

3.6.4 Operation Messages An operation message reports the sampler’s status as it runs a program. An example is shown below.

3.7 Menu Trees Selecting a menu option will take you to a number-entry screen

or another menu screen. The screens are organized in a branching structure that resembles a tree. Refer to Figure 3-1 for a simple chart of the menu tree for standard programming. The standard programming structure is different — much simpler — than the extended programming structure. Charts that show you most of the sampler’s screens appear in Appendix A.

The entire structure changes a little when a module is attached because the sampler adds a set of screens for a module as soon as it detects the module’s presence. The manuals for each module contain menu trees for its programming screens.

Section 4 Standard Programming

4.4 Pacing Sample pacing is the rate at which the sampler takes samples.

Standard Time Pacing and

Flow Pacing Screens for

Samplers without Flow

• When programming, you will be asked to select time or flow paced sampling. Depending upon your choice, you will see one of the following screens:

Samplers with Flow Modules

Modules

TIME PACED

FLOW PACED

TIME BETWEEN

SAMPLE EVENTS:

__ HOURS, __ MINUTES

FLOW BETWEEN

SAMPLE EVENTS:

____ PULSES (1-9999)

Flow Pacing Screen for

FLOW BETWEEN

SAMPLE EVENTS:

____ Mgal

(0.001 -99999)

Depending on the type of pacing you select, the rate is controlled by the sampler’s internal clock or by inputs received from connected instruments.

Standard programming provides time pacing and flow pacing (refer to Step 7 in the previous two programming examples). In time-paced sampling, the interval between samples is a constant time interval. When you program the sampler for time pacing, the sampler prompts you to enter the time between sample events in hours and minutes. Time paced programs always take a sample at the start time.

Flow paced sampling requires a flow meter, flow logger, or a module. A flow meter or flow logger paces a sampler by sending an electronic signal to the sampler after measuring a specified volume of liquid. Because each pulse represents a volume interval, flow pacing rates are proportional to the volume of water flowing through the channel.

When you program the sampler for flow pacing and are using a flow meter or flow logger, the sampler prompts you to enter the interval between sample events in pulses. The sampler initiates a sample event when the set number of pulses is received. Programs that are flow paced do not take a sample at the start time.

After setting the program start time, you will be prompted to enter a maximum run time of zero to 999 hours. If you would like the program to run indefinitely, enter 0 (zero) for maximum run time.

The flow pacing screens change when you attach a flow module (see example to the left). Because the sampler is more closely integrated with the modules, the standard flow pacing screen prompts you for the flow volume between sample events instead of pulses between events. The flow volume units displayed are what you had previously programmed.

4.4.1 Trigger Pacing Teledyne Isco 4200 Series Flow Meters and 4100 Series Flow Loggers send pulses for trigger pacing. The flow meter or flow logger sends pulses at two different time intervals when trigger pacing a sampler. Trigger pacing, for example, lets you sample less frequently when the trigger condition — a condition based on level, flow, or rainfall — remains below a set point. The intervals are determined by the flow instrument’s program settings for trigger pacing.

When conditions change and readings pass the set point, triggering the new rate, you can sample more frequently. Or, when the trigger condition is a clock setting, the instrument changes the pacing interval according to the time of day. Using a clock trigger condition, for instance, the flow meter or flow logger can pace the sampler slowly at night and more frequently during the day. (For more information about trigger pacing, see your flow meter or FLOWLINK manual.)

4-5

6712SR Refrigerated Sampler Section 4 Standard Programming

The flow meter or flow logger sends the same pulse for both flow and trigger pacing, and the sampler cannot distinguish between them. Therefore, to program a sampler for trigger pacing, simply program it for flow pacing.

4.5 Distribution Distribution describes how the sampler is to deposit samples. A

sample is the volume of liquid deposited in a bottle. A sample event includes the full sampling cycle and may deposit a sample into more than one bottle.

In standard programming, you can program the sampler for these different distribution methods:

• Sequential

• Bottles Per Sample

•Samples Per Bottle

•Composite

4.5.1 Sequential In sequential distribution, the sampler deposits one sample in each bottle. A sequential sample represents a “snapshot” of the flow stream at a point in time.

4.5.2 Bottles Per Sample In bottles per sample distribution, the sampler deposits a sample in each of a set of bottles. A bottle set includes at least two bottles but may include all bottles. Use bottles per sample when the volume to be collected is larger than the amount one bottle can hold or when you need identical samples.

4.5.3 Samples Per Bottle In samples per bottle distribution, the sampler deposits samples from several sample events in a single bottle before moving to the next bottle. Use samples per bottle distribution to collect a series of small composite samples.

4.5.4 Composite For single bottle configurations, samples per bottle distribution is known as composite sampling. A composite sample represents an average of the flow stream’s characteristics during the sampling period.

4.5.5 Continuous Sampling Sample programs can be run indefinitely by selecting “YES” at the “RUN CONTINUOUSLY?” screen. Continuous sampling resets the distribution when the distribution sequence is complete. That is, when the last bottle/set is reached, the next bottle/set is the first bottle/set. All pacing modes except RANDOM are supported.

When running a program continuously, the bottles must be serviced at regular intervals to prevent overfilling the bottles. The sampler assumes that the next bottle/set is empty and ready to receive samples.

The figure on the next page steps through the programming screens for sequential, bottles per sample, and samples per bottle distribution.

4.6 Start Times It is important to understand the difference between the time at

which you run a program and the program’s start time. Running a program simply means selecting RUN from the sampler’s main menu. The start time is the time at which the sampler begins the program’s first sample interval countdown. The start time is controlled by your selections from the start time screens.

Each program contains start-time settings that tell the sampler when to begin the program. When programming the sampler, you can select one of four start time options: NO DELAY TO START, DELAYED START, CLOCK TIME or WAIT FOR PHONE CALL.

• Select NO DELAY TO START when you want the sampler to start as soon as you select RUN.

• Select DELAYED START when you want the sampler to delay from 1 to 999 minutes before starting the program.

• Select CLOCK TIME when you want the sampler to begin the program at a specific time on at least one day of the week.

• Select WAIT FOR PHONE CALL when you want the sampler to begin the program after receiving a remote command to start.

4.6.1 How Do Start Times Wor k?

As soon as you select RUN from the main menu, the sampler checks the program’s start time settings. With a “DELAYED START” setting, the sampler starts a countdown to the start time. The period between the time you select RUN and the start time you’ve specified in the program is called the “delay to start time.”

When you run a program with “CLOCK TIME” settings, the sampler also starts a countdown to start time until the day of week and clock times are met.

The sampler may not collect a sample at the start time. The sampler must be enabled, and the pacing selected must call for a sample at start. In any event, the sampler checks the pacing settings and begins the pacing-interval countdown.

4.6.2 Sampler Enable/Disable

Teledyne Isco flow meters and flow loggers have a programmable sampler-enable feature that lets them enable (start) or disable (stop) a program according to certain monitored conditions. For example these conditions can be level, flow rate, pH, temperature, percent, rainfall, I/O; or a combination of two conditions.

The 1640 Liquid Level Actuator can also be used, as well as any other instrument that can ground the input to pin F. Grounding the input disables the sampler.

The sampler disregards disable signals during the delay to start time. However, when the sampler detects a disable signal at the start time, it suspends the program until it is enabled. The diagram in Figure 4-2 shows the sampler’s responses.

4.7 Running Programs To run a program, select RUN from the main menu. You may also

select YES at the RUN THIS PROGRAM NOW? screen at the end of the programming screens.

4.7.1 Run Time Screens While running a sampling program the sampler displays a

variety of messages that report the program’s status. For example, if the sampler has not yet reached the programmed start time, it displays the scheduled start time as well as the current time.

Once the program reaches the start time, you can determine the time of the next sample, the next bottle to receive a sample, sample distribution, and other information. Other messages appear while the sampler runs through a sampling cycle and takes a sample. When the sampler needs to report multiple messages, it alternates them, displaying each for one to three seconds.

4.7.2 Module Readings Samplers with an attached module display the module’s

readings: pH and temperature for the pH module; level, percentage, or flow rate for the 4-20 mA module; level, flow rate, and flow volume readings for the flow modules; level, velocity, flow rate, and positive flow volume readings for the area velocity module.

An * (asterisk) appears next to the reading if the module was unable to take a reading. If an asterisk appears, the reading displayed is the last available reading. Flow rates will be reported as zero flow if the error persists for more than five minutes (for a level or velocity reading that flow is calculated from).

If an entire reading is filled with asterisks, the value exceeds the number of characters that can be displayed. The sampler stores the actual reading in memory, so it may be collected later.

For those programs that have delayed or scheduled start times, the readings will be displayed while waiting for the start time. Keep in mind that any totalizer values will be reset at the start time. Module and sonde readings are also displayed after a program is complete, until a key is pressed.

It is not necessary to run a program to view module or sonde readings. Real time data can be viewed on the display by selecting “VIEW REPORT” from the main menu.

4.8 Interrupting a Running Program

You can interrupt a sampling program by pressing the Stop key while the sampler is waiting for the next sample event. Pressing Stop places the sampler into Manual Paused operation and records a manual pause in the sample event log.

In this state, the sampler allows you to access several functions. You can modify the program, reset alarms, take a grab sample, etc., without adversely affecting the running program. Modifying the program is limited to adjusting the pacing intervals, enable conditions and sample volume. The basic program structure, such as the type of pacing, can not be changed.

While in the manual paused state, the sampling program continues to operate as normal, with the exception of taking samples. If a sample was to be taken, it is skipped. The sampler records “sample skipped” in the sample event log and continues to operate as normal.

The manual paused state displays a scrolling menu with several options (see example below). Use the Arrow keys to scroll through the manual paused options and the ↵ key to make a selection. Return to the running program by selecting resume program or pressing the Stop key. If you do not make a selection, the sampler automatically resumes the original sampling program five minutes after the last key was pressed.

4.8.2 Resume Program Selecting this option will cause the sampler to exit the manual paused state and return to normal program operation. A manual resume event will be logged.

4.8.3 View Data This option allows you to view the data recorded by the sampler. See Reports on page 4-19 for more information.

4.8.4 Grab Sample When selected, you will be asked to enter the volume to be pumped. A sample will then be taken as if it is to be placed into a container outside the sampler base. Do this by removing the pump tubing from the bulkhead fitting. See Grab Samples on page 4-15. A grab sample event will be logged.

4.8.5 Pump Tube Alarm If the pump tube is changed, this option should be selected to reset the pump counts on the counter. This will remove the “WARNING: REPLACE PUMP TUBING” message that may appear while the program is running. A pump tube replaced message is logged. See Replacing The Pump Tube in Section 7, Maintenance.

4.8.6 Calibrate Volume When selected, you will be asked to enter the volume to be pumped. A sample will then be taken as if it is to be placed into a container outside the sampler base. Do this by removing the pump tubing from the bulkhead fitting.

After the sample has been pumped, you will then be asked to enter the amount actually delivered. Once you have entered the delivered volume and accepted the calibration, a volume delivered event will be logged.

4.8.7 Cal/Adj Parameters When the sampler is configured for operation with a module, this option becomes available. Selecting this option will display the appropriate level adjustment screens and/or the calibration screens. If the level is adjusted, an adjusted level event is logged. If a parameter is calibrated, an appropriate event is logged.

Calibrating a parameter probe will temporarily “turn off” the partition data storage and the sample enable/disable functions. These functions are disabled during the calibration and for five minutes after the program is resumed. During this time, parameter data normally collected at the data storage interval will be logged as a 252 error message.

4.8.8 Adjust Pacing This option is available when the running program is paced by Time, Flow Pulses or Flow Volume. If you select this option, you are asked to enter a new pacing interval. The sampler logs an interval changed event.

The original pacing interval continues to count down until you return the sampler to the running program (select resume program). If the new pacing interval is less than the original count remaining, the new interval is used.

4-13

6712SR Refrigerated Sampler Section 4 Standard Programming

If the original count remaining is less than the new pacing interval, the original count will continue to count down to the next sample event. Subsequent samples are then paced by the new interval.

4.8.9 Adjust Volume Select this option to change the sample volume within the limits of the currently programmed sample distribution. If you change a sample volume, a volume changed event is logged.

4.8.10 Power Used The 6712 has a “fuel gauge” that gives an indication of power usage. The controller keeps track of how much power has been consumed since the last time it lost power. If the controller is powered by an external battery, this fuel gauge can help you estimate the condition of the battery.

Keep in mind that the sampler has no idea as to how much charge was originally stored in the battery (or even if a battery is being used), and therefore has no idea as to the remaining capacity of its power source.

4.12 Calibrate Volume The sampler delivers accurate sample volumes without cali-

bration. If you find that sample volumes vary significantly from the programmed values, first check the suction line for proper installation. Be sure it slopes continuously downhill to the liquid source and drains completely after each sampling cycle. Then, compare the actual length of the suction line to the suction line length settings in the program to see that they match. Also check the pump tube for excessive wear and replace it if necessary.

You may want to calibrate when:

• A new pump tube is installed. Run the pump for five minutes before calibrating.

• The sample source is above the sampler.

• Sampling from pressurized lines (15 PSI Maximum).

4.12.1 Calibration Tips • For the best results, calibrate the sampler after it’s installed on site.

• Use a graduated cylinder for volume measurement.

• The sampler clears the previous calibration setting when you reinitialize the sampler.

• You cannot calibrate while the sampler is running a program.

• When the sampler delivers the sample, it runs through a complete sampling cycle, using the current settings for volume line rinses and retries. If it is a two part program, the sampler uses the volume setting for part A.

To calib rate:

1. Disconnect the pump tube from the bulkhead fitting.

2. Place the end of the tube over a collection container.

3. Follow the steps in Calibrating Sample Volumes in the margin.

4. Reconnect the pump tube to the bulkhead fitting.

4.15.1 Collecting Reports There are a number of ways to collect the reports:

581 RTD

event times with rainfall or module data.

• The Summary report, listing daily summaries of data collected. The Summary report may be rainfall and/or module data.

The sampler stores the data for each report in memory where they remain until you select RUN. Selecting RUN clears the memory so that it can store the data from the next program.

View reports (program settings, sampling results, and abbreviated summary reports) on the sampler’s display.

Collect the reports (except for summary reports) with a teledyne Isco 581 RTD and use a computer running flowlink or samplink to transfer the reports from the RTD to a file on the computer.

Collect the reports (except for summary reports) with an IBM PC or compatible computer running flowlink.

Collect the reports with and IBM PC or compatible computer running samplink.

4.15.2 Viewing the Data Because the display area is small, the data on the reports will be displayed a little differently from the data that is transferred to and viewed on your computer.

• For the Sampling Report, the sampler displays each program event, one at a time.

• For the Module and Rainfall Data reports, it displays daily summaries, instead of the full reports available with the rtd, Flowlink, or Samplink.

If you select Sampling Report or Rainfall (step 3 in Viewing Data, shown in the margin), the sampler begins displaying the report data. The sampler advances automatically through the report items, displaying each item briefly. While the sampler advances automatically through the displays:

• Stop the automatic displays by pressing Stop once. Then, use the arrow keys to move manually through the report.

• Return to the main menu by pressing Stop twice.

At the end of the report, the sampler leaves the last item displayed until you press:

• the arrow keys to move forward or backward manually through the report.

• Stop to return to the main menu.

4.15.4 Sampling Results Report

4.15.5 Combined Results Report

As the sampler runs a program, it records the program’s events. Program events include such items as sample events, program enables and disables, power losses, and so on. Table 4-3 lists each event with a short description. You can view the report by following the steps in Viewing the Data on page 4-19 or print the log as the Sampling Results report.

In the text file version of the report, sample-event entries include the time of the event as well as the sample and bottle numbers.

The sample column contains the sample number deposited into the bottle. This information reflects the distribution selected for the program.

The letters in the Source columns are codes for the cause of the event. The letters in the Error column are codes for the causes of missed samples. The source and error codes appear with explanations at the end of the report. A list of codes appears in Table 4-3.

The last column in the Sampling Results report records the pump counts for the sample event. Large variations in pump counts from event to event indicate fluctuating heads, a relocated suction line, or a temporarily clogged strainer.

At the time of each sample event, the sampler records the readings from each connected module, rain gauge, or SDI-12 sonde. The Combined Results Report presents the event time, sample and bottle number, and the respective readings from the device.

For flow modules, the readings are level and flow rate. For the pH module, the readings are temperature and pH. For the rain gauge and SDI-12 Sonde, the readings vary according to the selections enabled during the hardware setup in extended programming. When recording four or more sonde parameters, the Combined Results report will exceed the standard 40 character width. To read the additional columns, the data must be collected with Flowlink 4 for Windows software.

4.15.6 Summary Report This report summarizes the rain gauge or module data. The

types of readings are the same as those available to the Combined reports. The sampler compiles the data to present a daily total, the day’s average, maximum, and minimum reading, and a listing of hourly averages. The sampler then graphs the day’s readings.

In addition to viewing report data and configuring reports, the View Report option on the main menu lets you view system identification information.

The sampler reports the sampler model number, ID (identification number), and software version number as system identification notes. The sampler also reports the same information for an attached module.

The model and ID numbers remain unchanged through the life of the sampler. The ID numbers appear on the sampler’s reports and in files created by flowlink and samplink when they interrogate the sampler. The software packages use the ID number to make sure that data from different samplers is not combined in the same file.

The software version number changes when your sampler’s software is updated.

The system will also list any software options that you have activated on your unit. These software options are discussed in Section 5.

4.17 Programming for 700 Series Modules

The bay on the controller’s side accepts any of Teledyne Isco’s 700 Series Modules. These modules are optional accessories that are not required for operation of the 6712. However, the modules offer an economical way to combine flow-rate or parameter monitoring with sampling.

The programming of these modules is integrated with the programming of the sampler, so attachment of a module will cause different screens to be displayed, depending on the type of module and the selections you make while programming.

Two modules that are commonly used are the 730 Bubbler Module, which monitors a flow stream’s level and flow rate, and the 750 Area Velocity Module for monitoring a flow stream’s level, velocity, and flow rate. The following sets of screens give you an example of what screens you might see while programming the sampler and module. Refer to Table 4-1 (which does not have a module attached) at the beginning of this section to compare the sequence of screen displays.

Section 5 Extended Programming

All of the sampling features available with standard programming screens, discussed in Section 4, are available with extended programming screens. However, the extended screens provide several additional features and some screen display differences which are discussed in this section. The menu flowcharts for both sets of programming screens are in Appendix A, Menu Flowcharts.

Note

This section assumes that you have read, and are familiar with, the instructions in Section 4, Standard Programming!

5.1 Extended and Standard Mode

5.2 One-Part and Two-Part Programs

The sampler is shipped with factory default settings in standard programming mode when you first turn the sampler on. The start-up screen tells you which programming mode the sampler is currently using. You can switch between programming modes by entering a numerical command at the main menu:

At the main menu type 6712.2 to enter extended programming mode.

At the main menu type 6712.1 to enter standard programming mode.

RUN “EXTENDED 1”

PROGRAM

VIEW REPORT

OTHER FUNCTIONS

Main Menu for Extended Mode

Extended programming lets you set up a “one-part” program or a “two-part” program. One-part programs let you fill all bottles of the tub with one set of pacing, distribution, and enable settings. Two-part programs add an additional set of extended pacing, distribution, and enable screens to the sampling program. Each set of screens is called a program part. The program parts are simply called part ‘A’ and part ‘B’. Both parts share the program settings for suction-line length, suction head, and rinses and retries. They also share one start-time setting.

5-1

6712SR Refrigerated Sampler Section 5 Extended Programming

Each part has its own group of bottles. Because settings for each part are independent of each other, the sampler, when running a two-part program, fills each bottle group as if they were being filled by two different programs. Two-part programs finish when both parts are done.

Two-part programming is ideal for sampling storm events. Many storm-water run-off monitoring permits require a first-flush grab sample within the first 30 minutes of the storm event and flow-paced samples during the remainder of the event. With a two-part program, you can set up part ‘A’ for the first-flush sample and part ‘B’ for the remainder. Table 5-2 shows a storm-water sampling program.

5.3 Storage for Extended Programs

5.3.1 Selecting a Stored Program

The sampler stores five sampling programs: one standard and four extended. Program storage eliminates the need to reprogram the sampler with frequently used settings. This feature is especially useful for complex extended programs such as two-part programs or programs with many nonuniform-time settings.

Teledyne Isco ships the sampler to you with factory programs that you can modify to suit your own needs. All four extended programs are identical to each other.

The stored programs will also save your 700 Series Module program settings and any sampler enable conditions using rain gauge data or SDI-12 sonde parameters. These program settings remain as long as you do not change the type of module, or change the rain gauge or SDI-12 Hardware Setup.

When the sampler is in extended programming mode, it always has one current and three noncurrent programs, each occupying a permanent location in memory. The first time you access the extended mode, the current program is “EXTENDED 1,” one of the factory extended programs. The name of the current extended program appears in quotations on the first line of the main menu.

The factory programs are named “EXTENDED 1,” “EXTENDED 2,” “EXTENDED 3,” and “EXTENDED 4." You can rename them with more descriptive names, making them easier to identify. The program name is one of the extended program’s settings.

After selecting a stored program, review the settings with the quick view screens. Each sampling program stores all the settings required by the sampler to run a program. These settings include the bottle-kit information (number of bottles and the bottle volume), the suction-line length, the site description, start times, and so on.

If you use the same program at two sites — each requiring different bottle configurations, suction line lengths, or other details — always check these settings before running a program. You may need to make minor changes to the program to make sure the settings match your equipment.

5-2

6712SR Refrigerated Sampler

Section 5 Extended Programming

The current program is the program you see when you select PROGRAM from the main menu and page through the programming screens. It is the program the sampler uses when you select RUN from the main menu.

You cannot delete programs, but you can modify them as often as necessary. To run a program with different settings without losing the settings in your current program, select a stored program and modify its settings.

For example, assume you have been running the current program, named “EXTENDED 1,” at site A for several weeks. This program contains all the settings you need for site A, and you don’t want to lose those settings.

Nevertheless, you need another program because you want to move the sampler to site B, so you select “EXTENDED 2” and modify it for site B. The settings in “EXTENDED 1” are preserved automatically. When you return the sampler to site A, you won’t need to reprogram the sampler. Merely select “EXTENDED 1” again, double-check the program settings, and run the program. To select an extended program, follow the steps in Table 5-1.

5.4 Programming for 700 series Modules

5.5 Programming SDI-12 Sondes

The bay on the controller’s side accepts any of Teledyne Isco’s 700 Series Modules. These optional accessories are not required to operate the 6712. However, the modules offer an economical way to combine flow-rate or parameter monitoring with sampling.

Two modules that are commonly used are the 730 Bubbler Module, which monitors a flow stream’s level and flow rate, and the 750 Area Velocity Module for monitoring a flow stream’s level, velocity, and flow rate. Section 4 contains two examples of programming for modules. Module programming is the same in Extended as it was in Standard programming.

As an option, the 6712 accepts up to 16 parameters from up to ten sensors with SDI-12 addresses from 0 - 9. The data parameters used by the sonde and sampler must match. Certain vendors’ sondes, such as Hydrolab and YSI, have enhanced commands that facilitate “plug and play” setup. These Teledyne Isco Ready sondes can tell the 6712 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.

For more information about programming SDI-12 sondes, refer to Section 6.

5.6 Programming Examples

In addition to the features available with standard programming, and discussed in Section 4, extended programming offers:

• Nonuniform time pacing

• Random interval pacing

•Event pacing

• Multiple bottle compositing

• Time switched bottles or bottle sets

• Programmable sampler enable

• Pauses and resumes

• Two-part programming

• Automatic or user-defined suction head

• Suction line rinses

• Sampling retries

This manual provides several programming examples. Some, demonstrating simple tasks, appear in the margins. Others, demonstrating more complex tasks, appear as examples. Table 5-2 on the following pages steps you through a storm water runoff sampling using extended programming.

5-4

6712SR Refrigerated Sampler

Section 5 Extended Programming

5.6.1 Storm Water Runoff Sampling

Storm water runoff sampling is an ideal application for two-part programming. Typical monitoring permits require that a series of timed samples be taken during the initial portion of the storm event, followed by flow paced samples during the remainder of the event.

This example assumes that a Rain Gauge and a Bubbler Flow Module are connected to the sampler.

Note

To enable the Bubbler Module programming screens, insert the module before turning on the sampler

Using a 24-bottle kit, it divides the bottles into two groups, with six bottles assigned to part ‘A’ and 18 to part ‘B.’ The sampler will begin taking samples after being enabled according to programmable enable controls; that is, when the rain gauge detects 0.15 inches of rainfall in 30 minutes, and the module detects a flow stream level of more than 0.25 feet. Because both program parts use the same enable settings, the sampler will enable both parts at the same time. A list of settings for the program follow:

• Program type: Extended.

• Program name: STORM.

• Site description: SITE 54.

• Units: Length – Ft, Flow Rate – gpm, Flow Volume – gal

• Mode of Operation: Flowmeter, Flow-Insert, Round, 12"

• Bottle kit: 24, 1000-milliliter bottles.

• Suction-line length: 5 feet.

• Suction head: Auto suction head.

• Line rinses: None.

• Sampling retries: None.

(0-3)

Suction head is the vertical distance between the surface of the liquid source and the sampler’s pump. At each sample event, the sampler determines the suction head automatically.

In extended programming, you can manually enter the suction head if you want. Select ENTER HEAD only when the head remains stable and you can measure it accurately.

Rinses and retries are extended programming features. You can program the sampler to rinse the suction line automatically. During a line rinse cycle, the sampler draws liquid through the line to the liquid detector. As soon as it detects liquid, the sampler reverses the pump to purge the line.

The sampling retries feature lets you set the number of times, from 0 to 3, that the sampler tries to detect liquid in the line before skipping the sample.

5.9 Pacing

Sample pacing is the rate at which the sampler takes samples.

EVENT PACED

NONUNIFORM TIME

5.9.1 Event Pacing To program the sampler for event pacing, select event paced.

5-12

Depending on the type of pacing you select, the rate is controlled by the sampler’s internal clock or by inputs received from connected instruments.

Standard programming provides time pacing and flow pacing, which are described in Section 4. Extended programming provides additional pacing types, so its pacing screen (see example in margin) has four items listed instead of two.

“Uniform time” pacing is identical to “time” pacing in standard programming. “Flow paced” is the same for both types of programming. Event paced and nonuniform time pacing are described below.

Refer to Table 5-3 for an example of event paced sampling that uses three event conditions.

Up to fourteen event conditions can be defined (for two-part programs, up to fourteen event conditions can be defined for each part). An event will occur when any of the programmed event

4.5 Distribution Distribution describes how the sampler is to deposit samples. A

4.5.1 Sequential In sequential distribution, the sampler deposits one sample in each bottle. A sequential sample represents a “snapshot” of the flow stream at a point in time.

4.5.3 Samples Per Bottle In samples per bottle distribution, the sampler deposits samples from several sample events in a single bottle before moving to the next bottle. Use samples per bottle distribution to collect a series of small composite samples.

4.5.4 Composite For single bottle configurations, samples per bottle distribution is known as composite sampling. A composite sample represents an average of the flow stream’s characteristics during the sam­pling period.
