2-1

Platinum/Optima CVE Refrigerated Sampler

2.2 Positioning the Sampler

There are a few considerations when selecting a site for the sampler. The foremost concern should be personal safety.

The installation and use of this product may subject you to dangerous working conditions that can cause you serious or fatal injuries. Take any necessary precautions before entering the work site. Install and operate this product in accordance with all applicable safety and health regulations, and local ordinances.

WARNING

If this product is used in a manner not specified in this manual, the protection provided by the equipment may be impaired.

WARNING

This product has not been approved for use in hazardous locations as defined by the National Electrical Code.

WARNING

The sampler is heavy. When lifting, use a two-person lift from the right and left sides. When possible, move the sampler using a two-wheeled hand cart from the side. To prevent damage to the refrigeration system, do not tip the sampler more than 45°.

2-2

Section 2 Installation

Dangerous Locations – If you must enter a manhole, confined space, or other dangerous location to install the suction line and strainer, observe standard safety precautions.

Support – The sampler should be installed on a surface capable of safely supporting the sampler, full liquid containers, and personnel.

AC Power – The mains line cord is the disconnect device should you need to remove power. Therefore, the electrical power outlet should be accessible.

Environmental – The sampler is designed for outdoor use. Refer to Table 1-2 for environmental specifications. When possible, avoid subjecting the sampler to chemical attacks and direct sunlight.

Avoid Submersion – The sampler is rated NEMA 4x (IP66), which does not protect from submersion. In the event of submersion, liquid entering the refrigeration system could permanently damage the sampler; liquid entering the bottle compartment could contaminate the collected samples. Liquid entering the electrical compartment for the refrigeration system could result in a short circuit and possible shock hazard.

Liquid Sample Collection Point – It is best to keep the distance between the sampler pump and the collection point as short as possible. Also, the pump inlet should be located above the liquid surface to be sampled with no liquid traps. Gravity will aid suction line rinses and allow the line to drain, thereby reducing the

2-3

Platinum/Optima CVE Refrigerated Sampler

possibility of sample cross-contamination. Refer to Table 1-2 for maximum suction line lengths and suction head heights.

Security – The sample compartment and control panel have a padlock feature, but the location may need additional security to prevent tampering or vandalism.

Accessibility – The sampler must be installed in a location where personnel can easily exchange bottles and perform routine service.

The sampler requires about 2600 square centimeters (925 in

) of floor space. Additional space must be allowed in front of the sampler, at its left and right sides, and above the sampler. Do not block access to these areas. Obstructions will make routine servicing activities difficult or impossible.

The back of the sampler may be placed against a wall. Allow free air flow on both right and left sides of the sampler, particularly at the vents. Unrestricted air flow behind and around the sampler will allow the refrigeration system to work efficiently.

Level Surface – The sampler should be placed on a level surface and the feet on the refrigerator body should be adjusted to prevent tipping or spills. If the sampler is not level, the sample liquid may miss the bottle mouth.

To level the sampler, place a bubble level on the top of the refrigerated compartment.

2-4

Section 2 Installation

CAUTION

Do not tip the sampler on its side or back. Tipping the sampler more than 45° might cause oil to run into the compressor inlet, which can permanently damage the refrigeration system.

2.3 Connecting Power

WARNING

Before connecting the sampler to an AC power source, be familiar with the Electrical Requirements listed at the front of the Installation and Operation manual.

The factory assembles the sampler for either 115 VAC/60 Hz, or 230 VAC/50 Hz. The serial number label located inside the control cover identifies the AC power configuration of your sampler. You cannot convert the sampler in the field.

• The mains power cord for 115 VAC samplers is equipped with a NEMA 5-15P plug for standard North American outlets.

• The mains power cord for 230 VAC samplers is equipped with an EU 1-16P plug for standard CEE 7-7 European outlets.

• For other types of outlets that supply compatible AC power, convert the mains

2-5

Platinum/Optima CVE Refrigerated Sampler

power cord plug with a locally-purchased

adapter. Plug the mains power cord into the outlet. The sampler control panel will briefly show this start up display.

Note

The refrigeration system must sit for 24 hours before powering up. This allows the compressor oil to drain back into the compressor if the unit was tipped on its side any time dur ing shipment or during installation.

2-6

Section 2 Installation

2.4 Installing a Bottle Kit

The sampler can hold 1, 4, 12, and 24 bottles. Each of these bottle configurations are supplied as a kit (see Table 2-1), which is normally ordered with the sampler or when you desire to change the bottle configuration.

2.5 Attaching the Suction Line

Note

The suction line is the tubing from the sampling point to the sampler intake fitting. The sampler typically uses a

/8inch ID (9 mm) suction line of lengths from 3 to 150 feet. Teledyne ISCO offers vinyl or PTFE-lined suction lines. The PTFE-lined tubing has a polyethylene jacket to protect it from kinks and abrasions.The vinyl suction line contains a very low parts-per-million level of phenols. If phenol content affects your sample analysis, use the PTFE-lined suction line.

2-13

Platinum/Optima CVE Refrigerated Sampler

Teledyne ISCO ships suction line in standard lengths of 3.0 m (10 ft) or 7.6 m (25 ft). Either length should be cut to the shortest length feasible for the installation. When installed, the line should run the shortest possible distance from the collection point to the sampler, preferably with a gradual upward slope. Excess suction line should be cut, not coiled. Coiled suction line will hold liquid between sample events which could cross-contaminate samples or freeze in cold climates. If the standard lengths are too short, or if you are cutting

compatible

/8inch ID suction line from a bulk

spool, you can use lengths up to 45 m (150 ft).

2.5.1 Vinyl Suction Line

The sampler inlet fitting is on the left side of the samplers. fittings are available to choose from. The sample line is

/4” clear PVC tubing which is connected to the

/2” and3/8” stainless steel barbed

/8”x5/8” (I.D. x O.D.) or1/2” and

a right-angle barbed fitting.

Figure 2-6 Left side of the sampler

2-14

Section 2 Installation

2.5.2 PTFE-lined Suction Line

Inserting a tube coupler into PTFE-lined suction line will damage the thin lining. Instead, refer to Figure 2-7 and the instructions below to attach PTFE-lined suction line to the sample tube:

1. Slide a short piece of silicone tubing over the inlet fitting and install a hose clamp (B).

2. Push about 20 mm of the PTFE-lined suction line into the end of the silicone tube (A).

3. Slide the clamp over the union and tighten. Do not overtighten; this might cause the tubing to collapse or restrict the flow.

To attach the strainer to the suction line, carefully screw the strainer’s threaded connector into the suction line. If attaching the strainer to an PTFE-lined suction line, heat the suction line end before threading the strainer

2-16

Section 2 Installation

into the line. Warming PTFE-lined tubing will make it more pliable to avoid damage.

2.6.1 Alternative to Strainers

When sampling from high velocity streams with heavy suspended 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, a pre-sample line rinse removes any debris over the tubing entrance.

2.6.2 Max Unanchored Length

During a pre or post-sample purge or line rinse, the suction line is filled with air which might cause the suction line and strainer to float. If the length of the suction line and strainer exceeds the listed value, securely anchor the strainer.

Even if the maximum length is not exceeded, it is a good idea to anchor the suction line and strainer when sampling from high velocity or turbulent flow streams.

2-17

Platinum/Optima CVE Refrigerated Sampler

2.7 Routing Suction Line and Strainer

Route the suction line so that it has a continuous slope from the liquid source to the sampler. This helps to drain the line during pre and post-sample line purges and rinses. If a suction line exposed to freezing climates does not fully drain, there is a risk of liquid in the suction line becoming frozen. Frozen liquid will cause the sample collection to fail. A warm sampling source can usually prevent this, provided there are no traps or low spots in the suction line. Some extreme situations may require more protective measures, such as insulating the suction line or applying heat tape or adding a pump heater.

For representative samples, place the strainer in the main current of the flow stream, not in an eddy or at the edge of flow. Placing a strainer at the bottom may produce samples with excess heavy solids and no floating materials, while placing it at the top may produce the opposite conditions.

2-18

Section 2 Installation

2.8 External Devices

You can connect the sampler to an external instrument (Figure 2-9) for a variety of reasons. Typical reasons include:

• Receiving flow pulses from a flow meter device for variable time.

Figure 2-9 External device connections are

located on the upper right side of the sampler

• Receiving an enable pin signal to enable sampler operation once site conditions warrant sample collection.

• Receiving a linear 4-20 mA analog or pulse representation of the flow rate for variable time.

• Sending alarm signals when sampling events occur.

2-19

Platinum/Optima CVE Refrigerated Sampler

These types of connections can be categorized as Standard ISCO device connections or other device connections. Each type is discussed in Sections 2.8.1.

2.8.1 Other Device Connections

You can connect the sampler to receive a 4-20 mA signal, 0-5 VDC, 0-10 VDC or pulses from an external device.

CAUTION

Risk of equipment damage. Only experienced electronic technicians should make the connections to an external device.

To connect the external device, refer to Table

and select the appropriate pins. Connect the

3.4 Sampling Program Overview

The sampling program controls how often sample events occur and what should take place at each event. A sample event may happen when:

• Starting a flow paced program that is programmed to sample after a delay (Section 3.5.13).

• A time paced program reaches the first sample time and date.

• The programmed time interval has elapsed.

• The programmed number of flow pulses has been reached.

At each event, the sampler:

1. Resets the programmed flow or time pacing interval after initializing a sample.

2. Purges the suction line (see Section 3.3.3).

3-16

Section 3 Programming

3. Sends a closed contact while sample is taken. The sampler deposits the programmed sample volume into the bottle.

If programmed to deposit a sample volume in more than one bottle, the sampler:

a. Moves the table to the next bottle.

b. Deposits the programmed sample

volume into the bottle.

c. Repeats steps 3a and 3b until the

programmed number of bottles per event is reached.

4. Purges the suction line (see Section 3.3.3

There are five categories of sampling program instructions that control the above actions in an event. These categories include:

• Cycle: Parameters that configure the sampling cycle, purge, sample time, post purge, rinse, recycle, and consecutive samples.

• Sample Interval: Define what controls the sample collection interval based on Time or Flow.

• Bottle Option: Define which sampling type (discrete/composite) and the bottle configuration.

• PGM Run Options: Configure program run options including auto rerun, delay start, float, fault, timed stop, and bottle limit.

3.4.6 Program Events

Each program’s scheduled events are defined by a list that can be accessed via the P

ROGRAM

EVENTS group. Each event on that list has three associated values:

• The type of event (start, stop, pause, halt,

resume or manually sample).

• The days of the week on which the event

will be executed.

3-27

Platinum/Optima CVE Refrigerated Sampler

• The time of day on those days at which the event will be initiated.

Select the “End List” event when you have programmed all the desired program events. You can remove events by disabling the event for each day of the week.

3.5 Programming Steps

To begin programming from the PGM READY screen, use the menu F3 (SEL) button to select

ROGRAM. Press the F3 button to display the

P first programming screen P

3.5.1 Sample Pacing

There are two pacing methods for sampling programs, Time Paced and Flow Paced.

• Time Paced sampling programs use the sampler’s internal clock to collect samples at a constant time or variable time interval. When you program the sampler for time pacing, the sampler will prompt you to enter the time between sample events in minutes.

• Flow Paced sampling programs require an electronic signal from a flow measurement device. This electronic signal is typically a dry contact (pulse) that indicates some user-programmed volume interval has passed through the flow channel. Because each pulse represents a volume interval, flow pacing rates are proportional to the volume of

ROGRAM #1.

3-28

Section 3 Programming

water flowing through the channel. This is sometimes called “Constant Volume Variable Time (CVVT) sampling.” When you program the sampler for flow pacing, the sampler will prompt you to enter the number of pulses to count before

collecting a sample. All Teledyne ISCO flow meters provide a compatible flow pulse. Non-ISCO flow measurement devices may be used to paced the sampler. Refer to Section 2.8– External Devices for more details.

Use the F3(S flow option, then press the E

EL) button to select the time or

NTER button.

3.5.2 Time Paced

Time Paced Only – Use the number buttons to enter the time interval in minutes. The sampler collects a sample each time this interval elapses while the program is running.

3.5.3 Flow Paced

Flow Paced Only – Use the number buttons to enter the flow interval as a number of pulses. While the program is running the sampler counts the flow pulses until this number is reached. At this time the sampler collects a sample and resets the interval to begin counting again.

The volume that each flow pulse represents is a fixed volume. Refer to the instruction manual of the flow measurement device.

3-29

Platinum/Optima CVE Refrigerated Sampler

For example, consider an ISCO 4250 Flow Meter programmed to send a flow pulse every 100 gallons. If you are required to collect a sample every 10,000 gallons, you would enter 100 flow pulses. 10,000 gallons  100 gallons = 100 pulses.

If the flow measurement device sends flow rate data via a 4-20 mA current loop instead of flow pulses. The sample program needs to be changed in the SMPL. I

NTERVAL menu. The

sampler assumes that the current is linear from 4 mA at zero flow to 20 mA at the full-scale flow rate.

1. Select the flow input type to 4-20mA.

2. Enter the maximum flow rate (MAX. LPM).

3. Enter the liters between each sample (SMPL

LITERS).

Example: Consider a flow meter output to 20 mA at 1,000 liters per minute, the peak flow rate of the channel. If you are required to collect a sample every 5,000 liters, you would enter 5,000 in the SMPL. L

ITERS menu. The sampler

would totalize the flow base on the MAX LPM and the flow signal. The sampler will totalize the liters based on the flow signal. There are no flow calculations needed, the sampler does that for you.

3.5.4 Bottles per SampleEvent

Multiple Bottles Only – The sampler places a sample volume in one bottle or sets of bottles at each sample event. Use this screen to enter the

3-30

Section 3 Programming

number of bottles to repeat the sample volume at each sample event. The effect of this number is illustrated below.

Distribution scheme with one bottle per sample event. Samples events are numbered.

Distribution scheme with two bottles per sample event.

Distribution scheme with three bottles per sample event.

3.5.5 Switch on Time Indexing

Multiple Bottles Only – The sampler can switch bottles at regular time intervals. Use timed indexing to switch Bottles/Sets based on time.

Multiple Bottles Only – If you selected Switch on Time, use the number buttons to enter the desired time interval for bottle set switches.

3.5.6 Real Time Indexing

3.5.8 RunContinuously

Sample programs can run indefinitely or stop by going to P

GM RUN OPTS and then to BOTTLE

LIMIT. Select PGM.CONTINUE to run the program continuously or P

GM STOP to stop the

program when complete. 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.

In this mode, the sampler assumes that any filled bottles are replaced and ready to receive samples while the program is running, thus the pacing interval is never interrupted.

If you select PGM S

TOP, the sampler will run

until it completes the distribution sequence, at which time it stops the program and reports

ROGRAM DONE. The sampler will wait in this

P state until the bottles have been emptied and the program is restarted.

If your sampler is configured for composite sampling, refer to Section 3.5.14 for instructions on continuous sampling.

3-33

Platinum/Optima CVE Refrigerated Sampler

3.5.9 Sample Second

Enter the number of seconds it will take to fill the sample chamber and touch the liquid-sensor electrodes. The sample seconds must exceed the number of seconds to fill the chamber. When the liquid-sensor is activated, the timer stops and the program goes to post purge.

3.5.10 Flow Pulses, Analog Input

Time Paced Only – If you are collecting sample volumes dependent on flow (Section

3.5.11), select which type of flow rate input is provided by the external flow measurement device (see Section 2.8).

3.5.11 CompositeSamples

Single Bottle Only – Use the number buttons to type the number of composite samples to take. Press the E

NTER button to accept the

value. The sampler does not calculate the maximum

number of samples. Use caution when selecting the maximum number of samples per bottle so they do not overfill.

• If you selected continuous in the B

OTTLE

LIMIT menu, the sampler collects samples without regard for the total number of samples.

• If you enter continuous, keep in mind that the sampler might overfill the bottle.

3-34

Section 3 Programming

• If you enter STOP, the program will stop

when the program is done.

• The full bottle switch stops the sampler

from taking samples when the container is full.

3.5.12 Pressurized Line

4.1.2 Start Time Delay

If the program is set for NO DELAY TO START (Section 3.5.13), the sampler immediately begins to operate according to its C

ONFIGURE

and PROGRAM settings. If the program is set to use a start time, the

sampler will wait for the specified time and date. During this delay, the display shows the current time/date and program delay time/date.

When the programmed start time and date match the sampler’s time and date, the sampler program begins to run.

4.1.3 The Run State

Because the sampler operation is fully automated, no user intervention is required. Should there be a need to check on the running program, you can view the sampler display. It always reports the current state or operation and the refrigerator temperature.

4.3 Post Sampling Activities

Post-sampling activities include:

• Viewing the Log (Section 4.3.1)

• Retrieving the Refrigerator Temperature Log (refer to the Installation and operation guide)

• Removing the sample bottles (Section

4.3.3)

4.3.1 View the Log

The sampler records events during the running program and summarizes them in a log. This log is held in the sampler memory under ARC:LOG:1. The current log file that is running would be L stopped or program done the current log file goes to L

OG #2. The sampler will record and

display multiple log files. To view the log after the completion of a

program, or in the run mode press the #5 button. To view different log files scroll using the up and down arrows to access different file numbers.

Section 4 Operation

While viewing the log, you can:

• Step forward through the L

OG screens by

pressing the up or down buttons.

• Pressing the M

ORE and DETAIL buttons

will access the sampling data.

• Exit the log by pressing the B

ACK button.

The log generally contains the following information:

1. The number of samples collected (rc appears only if some samples required recycling)— this example indicates the sampling run that commenced at 11:01 AM on July 24 collected 2 samples].

2. If recycle was activated, the log reports the number recycles and the alarm output is activated.

3. That archived data can be reviewed from the user interface panel by pressing the 5 key when the selected program is running

(or waiting to be started), but not while the

DMINISTRATION or PROGRAM menu is

A active. The first line of the resulting display will indicate you are viewing log file 1, in which data for the current (or pending) sampling run is being (or will be) recorded.

4. Bottle type, number and size of the containers to which those samples were discharged.

5. If a log file’s fourth screen indicates one or more exceptions were encountered, pressing

ETAIL [F3] key will display the

its D timestamp and type of the first such exception detected during that program run. For example:

Section 4 Operation

If power was lost during the program, the log reports the time of the power failure event and the time the power was restored.

6. Pressing the D

ETAIL [F3] key while viewing

any sample container’s screen will display the timestamp, as well as, the time needed to collect the first sample that was discharged to that container. You could then display the same information for each of the other samples in that container by pressing the up and/or down keys.

The refrigerated cabinet temperature is logged with each sample.

7. The log reports the average refrigerator temperature and the minimum and maximum recorded temperatures.
