Section 1. Product Overview

1.1 Introduction

The PVS4100, PVS4120 and PVS4150 Portable Samplers are automatic liquid
samplers for water and wastewater applications. PVS Samplers are capable of
gathering fluid automatically from a variety of sources, including containers,
open channels, sewers, pipes, and any open source of water.

Samplers are designed for reliable unattended sample collection. Portable units
are capable of keeping the temperature of the deposited liquid at 4ºC (39.2ºF)
for up to 24 hours using crushed ice or ice packs until the samples are gathered
and brought back to the laboratory for analysis.

There are a variety of methods for depositing samples. Composite sampling is
used where samples are deposited, over time, into one container. Discrete
systems are used when multiple bottles are needed. These are also called
“sequential” systems, and involve a stepper with distributor arm which
dispenses the liquid into a bottle, then moves to the next bottle.

Operating temperature for portable samplers is 10ºC to 50ºC (50ºF to 122ºF),
adaptable down to 0ºC (32ºF) upon request.

Samples can be triggered by a variety of means. The internal clock on the
controller can be set to sample based on time/day (e.g. sample every hour).
There are also a variety of external inputs that can be connected to control
sampling using the optional external signal cable. Pulse count is useful for
sampling after a certain number of pulses have been reached (e.g. using a rain
gauge to trigger sampling). The 4-20 mA option is useful for flow-based
sampling (e.g. using a flow meter to trigger sampling after a certain volume of
water has passed by). External contact is used to control the sampler from
another data logger or PLC, and is useful when full external control is desired.
Level control is the option to choose when the application has starts and stops
(e.g. using a float switch to trigger sampling when water is present, then stop
sampling when the water drops below the set level).

When sampling is initiated, liquid travels through the intake tube into the
metering chamber. The amount of water taken is set mechanically using the
liquid sensing rod and the volume control tube, which means sample accuracy
is precise every time, usually within +/- 2% or +/- 2ml.

Once the pre-set amount has been reached, all excess liquid is purged from the
system, and the sample is dropped into a container. Sample containers range
from 500 ml (500 cc or 2 cup) wedges in discrete systems, to 9 liters (2.3
Gallon) containers for composite systems.

Intake tube is offered in either 3/8” (9.5 mm) ID or 5/8” (15.9 mm) ID, and can
be either Nylon-reinforced PVC or Teflon-lined PVC. Transport velocity varies
depending on height and distance being sampled. For most situations the
sampler pulls at over 1.5 m/s (5 ft/sec). For an in-depth speed chart, refer to
Section 1.3.7 Sample Transport Velocity

on page 1-15.

sampling. On composite (single bottle) samplers, this is replaced

with discharge tube.
17 Sample Container(s) The container(s) that the sample is deposited in can be made

from a variety of materials, shapes, and sizes. In discrete

samplers, there is a distributor arm that deposits samples into

multiple containers.
18 Retaining Plate Holds sample bottles down tightly (discrete samplers only).
19 T-Bar This bar is needed to hold the retaining plate down. It is

imperative that the bottles do not lift up even a little bit, as they

can interfere with the mobility of the distributor arm (discrete

samplers only).
20 Bottle-Guide Notch This notch is the location of bottle number one. It lines up the

middle section of the sampler so that the distributor arm can be

placed at the same location.

TABLE 1-3. Vacuum System Features

Number Item Description

1 Solenoid Valves Control the air flow from pump to sampler, either purging or

sucking.

2 Pump Located behind a sheet of metal, the pump does not come into

contact with any liquid whatsoever. It does all the drawing and
purging through using a vacuum and compressor.

3 Touchpad Controller Controls sampler program and offers status feedback on LCD.

4 Sample Distributor Rotates distributor arm between multiple discrete containers.

5 Distributor Arm Dispenses liquid from metering chamber into discrete container.

6 Discrete Sample Containers Multiple containers, always in a quantity divisible into 24

1.3.7 Composite and Discrete Overview

Discrete Sampling (PVS4100 and PVS4120 only) is sampling wherein
samples are taken into more than one container. Inside of the cooling chamber
is a stepper assembly which revolves 360° and delivers samples into separate
containers, ranging from 8 to 24 bottles. Discrete sampling is beneficial in
situations where change over time needs to be measured, such as measuring
different water characteristics over 24 hours. Labs and monitoring personnel
tend to rely on discrete portable sampling.

1-14

Section 1. Product Overview

Composite Sampling is for drawing water samples into one large container.
This is the simplest way of taking samples and typical for most situations
where a sampler is set up to measure effluent in one location. It is also
significantly less expensive than discrete sampling.

1.3.8.1 Using Velocity to Calculate Purge Time

Purge time of the sampler needs to be programmed based on the length of hose
and the velocity at which the liquid will travel through the hose. The formula is
l / v = p (length / velocity = min. purge time). Adding a few second to the
purge time is recommended to ensure the line is fully cleared of any
obstructions.

Example: 100 ft of hose, at 5 ft/sec, requires a minimum 20 second purge time.
100 / 5 = 20 seconds. The number input for purge time should be a minimum
of 20, but preferably 24.

Standard purge time for 25 ft of intake tube is 10 seconds. Although a standard
25 ft hose will sample in less than 4 seconds, 10 seconds is the minimum
recommended for proper clearing of the line.

1.3.8.2 Horizontal/Vertical Combinations

The velocity charts above measure only horizontal or only vertical. Most
applications will have combinations of both. With 200 feet of intake tubing,
PVS Samplers are capable of drawing a sample above 2 ft/sec at 20 feet of
vertical. At 23 feet of vertical with 200 feet of intake tubing, sampling may or
may not be successful, depending on altitude and other factors. For more

1-16

detailed information for your specific application, please contact a Campbell
Scientific applications engineer.

1.3.9 Special Systems

1.3.9.1 5/8 Systems

In applications with large particles or materials in the source liquid, a 5/8” ID
system will help prevent clogging. The added diameter adds 66% more volume
to the entire system. As of 2010, both composite and discrete samplers are
available in 5/8”. Smaller pump systems (PVS4120) have minimal capacity
running the larger volume of the 5/8” ID so the larger pump systems
(PVS4100) are recommended.

For a sampler to increase to a 5/8” ID, the following parts and components are
changed to allow for more volume: intake tube, volume control tube, all
fittings, metering chamber, metering chamber lid, discharge tube, sample
container cover, sinker or strainer, and the distributor assembly (for discrete
models).

1.3.9.2 MISA Systems – Teflon and Glass

Section 1. Product Overview

In applications wherein the water sample must be prevented from coming into
contact with any plastics, a MISA system is recommended. For example, when
testing for acid/base/neutral extractable organics and pesticides, the MISA
system will keep the final sample clean from any contaminants.

MISA stands for “Municipal/Industrial Strategy for Abatement,” and includes
changing all “wetted” components of the sampling system, i.e., everything that
comes in contact with the final sample. The chart below outlines the key
changes made to the sampler for a MISA system.

1.4 Portable Sampler Model Selection Guide

PVS Samplers come in a variety of models designed for variations in weight,
pump strength, battery, larger intake hose (5/8” ID), ease-of-transport, fitting in
manholes, discrete or composite sampling, protection rating for dust and water,
signal options, and budgets.

1-18

Section 2. Installation

2.1 Cabinet Positioning

Place the sampler on a level surface as close as practical to the sample source.
Refer to the speed charts for maximum expected lift and draw. Manhole
installation may require 3-point suspension harness.

Sampler must be located above sample source, or liquid will flood the machine.
For situations where this is not possible, please contact a Campbell Scientific
application engineer for solutions on pressurized sources.

FIGURE 2-1. Sampler Installation

2-1

Section 2. Installation

2.2 Intake Hose

Ensure the intake hose is submerged at all times throughout different flow
velocities.

CAUTION

Twenty-five feet of intake hose is provided with the
sampler. Shortening the hose is not recommended since
this length of hose provides sufficient back pressure to the
metering chamber, allowing the pump to efficiently expel all
solids into the sampler container. Coil any excess intake
hose in a manner to provide natural drainage away from
the sampler. To install intake hose, heat the end in hot
water and slip over volume control tube. Secure with hose
clamp provided.

Sample line should be routed so that it has a near continuous slope from the
sampler to the source liquid. This will help keep the sample line cleared and
fully drained. All excess line should be coiled neatly and without any vertical
loops.

2.3 Sinker / Strainer

Sinker or sinker/strainer is intended to keep sample line fully submerged in the
source liquid. A sinker/strainer should be used in situations with material that
clogs up a normal sinker, or where the standard sinker could stir up bottom
sediment.

Lead Sinker: SAM-23-28-01 Stainless Steel Sinker/Strainer: SAM-23-28-11

2.4 Storage

If the sampler is not to be used for an extended period of time, store the unit in
an upright position in a warm, dry location. If the unit has an integral battery,
recharge the unit prior to storage.

Acceptable storage temperature: -30ºC to +60ºC (-22ºF to +140ºF)

2-2

2.5 Signal Wiring

External input capabilities of the sampler are implemented by the use of an
optional external signal cable plugged into an external receptacle on the side of
the sampler. External inputs of different types can be used by choosing the
appropriate pair of wires in the cable.

On the PVS4150 the signal cable is combined with the AC Power cable, thus
limiting the number of connections possible.

FIGURE 2-2. External Signal Cable for PVS4100 and PVS4120

Section 2. Installation

IMPORTANT

Wiring to remote/external functions should AVOID ALL AC
POWER LINES if possible and/or be run in shielded cable
terminating the shield at the AC ground terminal at the remote
site.

2-3

Section 2. Installation

2.6 Installation Checklist

Check the following items prior to use of sampler:

1) Sampler is mounted securely and level.

2) Intake Hose: - Free of kinks.

- Properly installed into liquid.

- Properly connected to volume control tube on
metering chamber.

3) Discharge hose: - Free of kinks.

- Natural downward slope to sample container.

- Properly connected to (or in) sample container.

4) Power requirements: - Check battery electrical condition.

- Recharge if necessary.

2-4

Section 3. Operation

3.1 Operating Sequence

3.1.1 Sampling Sequence

SAMPLING PROCESS:

1. High pressure air purge of intake hose.

2. Liquid is drawn into the metering chamber, up to the liquid sensing rod.

3. All excess liquid is purged from the system down to the level set by the

volume control tube.

4. The sample is then released into either one composite container or one of

several discrete containers.

The sampling sequence begins with a high pressure air purge of the intake
assembly to remove residual liquid and obstructions. Upon completion of the
pre-purge cycle, the system converts to a vacuum state, drawing the sample
through the intake hose into the metering chamber. The system then
pressurizes, ejecting excess fluid back through the intake line until the
predetermined sample volume is achieved. The sample is then deposited under
pressure into the sample container while the post purge again clears the intake
line of any residual liquid.

3-1

Section 3. Operation

3.1.2 Line Voltage Failure

Should the sampler, for any reason, not be able to draw a sufficient volume of
fluid to obtain a sample, the unit automatically initiates a second attempt.
Should a sample still not be delivered, the sequence will be abandoned and the
unit will await the next initiation. Upon two consecutive failures, the sampler
will suspend the sampling program until manually RESTARTed.

If programmed with the FAULT SHUTDOWN “disabled”, the sampler will
not make a second attempt to draw the sample, but will simply abandon it and
await the next sample initiation. Neither will the unit suspend the sampling
program after consecutive failures. This function is provided for use in the
event that the sample source may be lacking sufficient fluid from which to
draw, for a period of time , yet allows the sampler to continue operating
without a “FAULT SHUTDOWN” occurring. The second attempt is not made

to prevent unnecessary wear on the sampler.

Should the sampler have a factory installed internal battery or have an external
battery connected, the sampler will continue operating. The duration of
operation will depend on the capability and charge level of either battery. The
frequency and the length of each sample cycle will also have an impact on how
long the batteries will last.

3.2 Operating Instructions

3.2.1 Sample Volume Adjustment

Setting the desired sample volume is accomplished by adjusting the height of
the volume control tube within the metering chamber. The tube is mounted
through the top of the chamber with a gland nut fixing the position. To adjust
the sample volume, loosen the nut until the volume control tube may be moved
freely. Raise or lower the bottom end of the tube to the desired volume using
the lines provided on the side of the chamber as a guide (lines are spaced at 100
cc intervals with the exception of one at 50 cc). Tighten the gland nut to hold
the volume control tube at the desired position.

3-2

Section 3. Operation

IMPORTANT

NOTE

The volume control tube should always be located below the
liquid sensing rod.

Hold the bottom nut while loosening / tightening the top nut, or it
may become loosened from the metering chamber cover and
create an imperceptible leak in the vacuum system.

3.2.2 Liquid Sensing Rod

This probe, also called the “level control rod”, is used to stop the sample
intake. Always ensure that its lower end is located above the volume control
tube. Approximately 1” difference is sufficient. If the fluid intake is turbulent
within the metering chamber, more than 1” may be required to ensure
splashing of fluid does not trigger probe.

In applications with substantial oil or grease, the rods can become coated and
lose their conductivity. This is prevented by cleaning the rods regularly. In
extreme cases, extra SS wire can be wrapped around the liquid sensing rod to
increase its surface area.

IMPERATIVE: THE LIQUID SENSING ROD AND VOLUME CONTROL
TUBES MUST BE KEPT CLEAN TO ENSURE CONDUCTIVITY
NECESSARY TO DETECT THE PRESENCE OF THE FLUID.

Most PVS Samplers incorporate a Barrier Valve in the metering chamber
cover, where the tubing from the pump enters. It consists of a cage containing a
ball that will float if the sample should rise to the top of the chamber without
detection. Should rod conductivity fail, the fluid brings the float into contact
with an O-ring surrounding the pressure / vacuum port, sealing the entry to the
tubing and the pump (where the fluid may cause serious damage). This O-ring
Barrier Valve should be inspected regularly and replaced as necessary.

Due to the restriction of Wetted Materials (i.e. stainless steel, glass and
fluorocarbons etc.), some models of the sampler do not contain this barrier
valve. In these units, a secondary liquid-sensing circuit may be added as a
precaution. This circuit is connected to the pump tubing fitting on the Metering
Chamber cover.

3-3

Section 3. Operation

3.3 Battery

3.3.1 Battery: Operating and Backup (optional)

CHARGING AND REVERSE POLARITY PROTECTION

The sampler will charge ONLY the factory installed internal battery. This
charging takes place continually as long as there is incoming line power.
Should the need arise to only charge the internal battery, as would be required
to store the sampler for an extended period of time, simply place the “ RUN /
OFF “ toggle switch in the OFF position, and leave the sampler power breaker
on. Twenty-four (24) hours should be sufficient to fully charge the battery.

The sampler is equipped with REVERSE POLARITY PROTECTION for
checking the connection of an external battery. When attaching an external
battery, be sure to check the reverse polarity indicator. If it is ON, reverse the
connections at the battery.

3-4

FIGURE 3-1. Battery Performance Curve

3.3.2 Battery: Microprocessor

SAMPLER CONTROLLER BACKUP BATTERY

The controller contains a 1/2AA, 3.6V lithium backup battery to maintain user
settings during loss of system power. If power is removed for any reason, the
controller will start a planned shutdown procedure which will save all user
settings while its operating voltage is reduced from 5V to approximately 3.3V.
The rate at which this voltage drops is slowed by the presence of a
supercapacitor. By the time the voltage has reached 3.3V, the controller has
safely stored all user settings and entered a “sleep” mode. This is an extremely
low-power mode which is maintained by a trickle of current from the lithium
battery, and can be maintained for many years under normal circumstances.

The battery is located on the top left hand side of the controller. It is accessible
by the removal of the clear cover, and should be changed under powered
conditions. Since the controller is a low-power device, this uncovering can be
safely done, taking care that no conductive implement contacts sensitive circuit
components.

If the controller starts to exhibit certain operating anomalies such as loss of
user settings after sustained power outages or an inability to “wake up” after a
normal shutdown, it may be due to a low or totally discharged backup battery.
To predict the probability of these events, regular examination of the battery
condition is encouraged. The battery status is easily determined while the
controller is active. The process will not affect a running program. Battery
status can be checked by use of the following touchpad sequence:

Section 3. Operation

VIEW, OTHER OPTIONS,

select MAINTENANCE, ENTER, then select B/U BATTERY TEST, ENTER

The display will then show “PASSED”, “LOW” or “FAULT”. The latter two
require battery replacement.

TO REPLACE BATTERY

1. Make sure the controller is powered.

2. Remove touchpad (clear) cover from the controller, remembering to

handle internal ribbon cable and connector with care.

3. Locate the battery holder on the normal left side of the circuit board. The

battery is a 1/2” cylinder about 1” in length. The positive (+) end of the
battery has a raised button. Note the button’s relative position in the
holder. It should be pointing away from the display side of the board.

4. Place new battery in holder, noting position of button with respect to the

polarity indicators in the holder.

5. Check battery status, as above. If necessary, locate small white button at

top of the control board (under display) and push to restore factory
defaults.

6. Replace cover securely and re-enter user settings.

Section 4. Maintenance

The following maintenance procedure should be performed at regular
intervals:

4.1 General Maintenance

1. Disconnect power.

2. Open metering chamber by removing wing nuts and chamber cover.

3. Clean volume control tube and level sensing probe with mild detergent.

Alternatively, exchange tube and probe with clean set. Do not use any
cleaner which may be harmful to the metering chamber cover. Do not use
solvents such as acetone, benzene, carbon tetrachloride or lacquer thinners.
Grease and oil may be removed with kerosene or aliphatic naphtha (non­aromatic).

4. Check and clean O-rings in metering chamber cover.

Replace if damaged, worn or brittle.

5. Clean metering chamber using mild detergent.

Do not use any cleaner which may be harmful to the clear acrylic, (e.g.
petrochemical solvents, as noted above.) Do not use abrasives or
“scouring” compounds.

6. Check discharge tubing for wear and replace as necessary.

7. Check pinch valve to ensure free movement.

8. If possible, run sampler through several sampling sequences in clean

water.

4.2 Testing System Vacuum

Using the (optional) built-in pressure / vacuum gauge, take a reading to ensure
system has no leaks. Optimal pressure is above 28 psi. Optimal vacuum should
be 12 psi or better.

If the system is not performing at its peak, try the following:

1. Check intake hose for leaks/kinks.

2. Check discharge tube, ensure it has no leaks and is in good shape.

3. Check all fittings to ensure they are tight.

4. Make sure when tightening and loosening the gland nuts on the top of the

metering chamber that the bottom nut is held secure and does not move on
the cover. Ensure the top nut is securely tightened, and use a wrench if
necessary.

Section 4. Maintenance

5. If still system is still not performing at its peak, inspect pump and all

pump tubing.

Section 5. Programming

5.1 General Programming

5.1.1 Guidelines

Controller settings may be changed at any time. Changes are termed NEW
ENTRIES. No NEW ENTRIES will be acted upon unless the controller is
RESTARTed. Once RESTARTed, all NEW ENTRIES become ACTIVE
SETTINGS.

Every time the controller is RESTARTed, all accumulators (i.e. SAMPLES
TAKEN, TIME REMAINING, REMAINING PULSES, etc.) are cleared

and the ACTIVE SETTINGS are reloaded unless NEW ENTRIES have been
made.

Remember - Start Delay is reloaded too !!

5.1.1.1 Flashing Text

Flashing text is the system wide prompt that indicates an input is required from
the user. Flashing words or duel flashing digits prompt for arrow keys to be
pressed to scroll through available options. A single flashing digit prompts for
a numeric key to be pressed. When the desired option or number is shown on
the display, press the ENTER key.

5.1.1.2 Real Time Clock

The controller has two basic timing modes. The simplest of these requires no
maintenance; it simply provides a “heartbeat” for various timed functions. The
other timing mode is the REAL TIME CLOCK that is used in several functions
and must be correctly set. This is likely the first item requiring

programming. Although time may have been set at the factory, time zone shifts
may require adjustment of the Real Time Clock.

5.1.1.3 Total Bottles

Since the number of bottles is usually determined by customer requirement at
the time of purchase, this variable will normally be set at the factory to match
the actual container hardware. Choices are restricted to a single container (as in
composite) or 2, 3, 4, 6, 8, 12 or 24. These all form instructions to the stepper
motor in how it will behave when the internal command is given to step to the
next container (as each step increment is 15°).

TABLE 5-1. Touchpad Button Descriptions

Button Description

MANUAL PURGE. Purges the intake line independent of program control, as long as a
programmed cycle has not started. Sampler starts its pump, creating pressure in the sample intake
tube to purge it of any excess material that may be present. Button must be pressed twice to purge
line. Sustained pressure on the key during the second press will cause purging to continue until the
key is released.

MANUAL ADVANCE. Distributor arm advances one position (e.g. to next bottle), dependent on
the equipment available (discrete samplers only). This action is NOT updated to any current
sampler program. Button must be pressed twice to initiate manual advance.

MANUAL SAMPLE. Initiate a single Sample Cycle. Sampler must not be engaged in a sampling
event at the time. This action and any resulting sample collected are NOT updated to any current
sampler program. The Bottle Position is NOT advanced. Program will continue uninterrupted.
Button must be pressed twice to initiate manual sample. Whether successful or not, the display will
read “MANUAL SAMPLE Completed”.

5.1.3 General Terms

Many of the functions available on the Touchpad have a variety of options to
enhance their capabilities. These options are programmable from the Touchpad
and require only that the sampler have the correct equipment configuration to
utilize them.

DISABLE

The display showing disabled will reflect the status of any function not being
used.

TIME/DAY

The basis for several timed functions is the Real Time Operating System. Time
(of) Day will be a means of setting the timing period for the START DELAY
function. The format is on a weekly basis, requiring hour, minute, AM/PM and
day inputs (HH:MM AM SUN). This means the Start Delay can be set to any
particular minute in a week.

INTERVAL TIME

Sampler operation can be controlled by fixed time intervals which do not
require Time/Day setting. SAMPLE INITIATION has an option whereby an
interval time can be set between sample cycles. The controller will cause
samples to be taken on a timed interval basis, continuing until the sample
program is completed by a full jar or operator intercession.

5-4

PULSE INPUT

This option will allow the controller to determine the sampler operation based
on external criteria. Pulses fed to an internal accumulator in the controller will
be compared to the setting entered by the operator and will cause a sample
cycle to start. The accumulator will reset immediately and counting of pulses

Section 5. Programming

will begin again. There is no loss of count the sample cycle. Pulse requirements
of the system are detailed in the specifications.

4-20mA INPUT

Where external devices do not themselves generate pulses in any relation to
their process but generate a current signal of 4-20 mA, this input option will
generate internal pulses proportional to the incoming 4-20 mA signal. These
can then be treated the same as the Pulse Input option and accumulated in the
controller to determine when a sample cycle will occur.

EXTERNAL CONTACT

The sampler controller can react to an external dry contact, otherwise known as
a zero-voltage contact, to activate a sample cycle on demand. This will
generally be when external conditions have caused a relay to close, requiring a
sample be taken at that time.

LEVEL CONTROL

The START DELAY function is a special case of the external contact option.
where the contact signal is required to be present for a pre-programmed time.
This enables verification of the signal where fluctuations may occur in the level
which would trigger samples at unwanted times. This is the only case in which
the START DELAY is not a single timed event. The operation of the sampler
after the level signal is verified will be controlled by whatever function is set in
the SAMPLE INITIATION. It will continue until the level drops or the
function is terminated by the controller. If the level drops before the function is
finished, any sample cycle already in progress will be completed and then the
system will shut down until the next verified level control signal.

COMPOSITE

A program option which determines that all the samples that are gathered will
be placed in a single container. The sample program terminates after a specific
number of samples.

MULTI-COMPOSITE

This option is used for discrete sampling applications, to deposit multiple
samples to one container before advancing the distributor mechanism to the
next container. The interval between each sample is controlled by the
SAMPLE INITIATION options. The multi-composite setting is
programmable up to 99 samples per container, for up to 24 containers
depending on the hardware configuration.

CONSECUTIVE

This option is used for discrete sampling applications, to successively deposit
one sample to each of a programmed number of containers on any given
sample initiation. The consecutive setting is programmable up to 99 containers
per sample initiation, although this may be severely limited by hardware
configuration.

5-5

Section 5. Programming

DAILY CYCLE

Allows the sampler to deposit equal sample volumes into a predetermined
number of containers per programmed day. Each day may have any number of
samples taken, dependent on the SAMPLE INITIATION mode chosen.
Deposits are made to as many as 9 containers per day, to a cumulative total of
24 containers. (e.g. Choosing a 24 bottle format, the sampler may be
programmed to deposit to Three (3) bottles on any six days of the week,
together with up to Six (6) bottles on the seventh). Timing is dependent on the
crystal-controlled Real Time Clock in the controller. The first program day will
be the current day the programming is done, unless the START DELAY
option is chosen to determine when sampling will begin.

TIMED STEP (Override)

This option will cause the sample distributor to step to a new container
regardless of the status of the SAMPLE INITIATION setting. For example,
the actual sampling may be under the control of a flowmeter and taking
samples based on the flow rate as determined by pulses or 4-20mA input to the
controller. When the user-programmed Timed interval has elapsed, the
controller will Step to a new container. The Timed Step can be set for any
interval up to 99 hours 59 minutes. Progress of the step timer can be viewed by
selecting View, Program Type and pressing ENTER twice. Thus you may
view the REMAINING TIME or the step timing.

To modify any of the settings individually
press the “SET” button followed by the
appropriate button based on what parameter

START DELAY is the function which will delay the beginning of a sample
program until certain external conditions are met. Upon meeting those
conditions, the sampler will initiate a sample cycle and then operate based on
the SAMPLE INITIATION parameters. Under START DELAY, flashing
text prompts the user to scroll through available options by pressing arrow
keys. These options only require that the correct equipment is present to utilize
them. The last option selected in previous programming will be the first to
appear on the display.

is being changed.

The display showing disabled will reflect
the fact that the function is not being used.

The basis for several timed functions is the
Real Time Operating System. Time (of) Day
will be a means of setting the timing period
for the START DELAY function. The
format is on a weekly basis, requiring hour,
minute, AM/PM and day inputs (HH:MM
AM SUN). This means the start of a sampler
program can be delayed up to seven days.

This option will allow the controller to
determine the sampler’s start of operation
based on external pulses. Pulses fed to an
internal accumulator in the controller will be
compared to the setting entered by the
operator. Pulse requirements of the system
are detailed in the specifications.

Where external devices do not themselves
generate pulses in any relation to their
process but generate a current signal of
4-20mA, this input option will generate
internal pulses proportional to the incoming
4-20mA signal. These can then be treated
the same as the Pulse Input option and
accumulated in the controller to determine
when a sample program should start.

5-8

Section 5. Programming

The sampler controller can react to an
external dry contact, otherwise known as a
zero-voltage contact, to activate a sample
program on demand. This will generally be
when external conditions have caused a
relay to close, requiring a sample program
be started at that time.

This option is a special case of the external
contact option. The key difference is that
the contact closure must be present for a
pre-programmed time, thus enabling
verification of the signal. This will
accommodate fluctuations as seen in a level
switch, thereby avoiding triggering of
samples at unwanted times. This is the only

case in which the START DELAY is not a
single timed event. Should the contact open

for the same pre-programmed time, the
sampler will (after completing any sample
cycle already in progress), halt the sampling
initiation and await the next verified signal.
At this time, the sampling program will
resume.

programmed in the steps above.

5.4.1 SAMPLE INITIATION Overview

SAMPLE INITIATION is the function that will determine the frequency that
samples are drawn. There is available on the Touchpad a variety of options to
enhance the capabilities of this function. When the Sample Initiation has been
chosen to be set, a list of options is presented as flashing text below the main
heading of the function selected. The list is advanced using the ARROW keys
(any direction) until the desired option is displayed. These options are
programmable from the Touchpad and require only that the sampler have the
correct equipment configuration to utilize them. The last option selected in
previous programming will be the first to appear on the display.

The display showing disabled will reflect
the fact that the function is not being used.

Sampler operation can be started at uniform
intervals. This option allows an interval time
to be set between sample cycles.

5-16

Section 5. Programming

This option will allow the controller to
determine the SAMPLE INITIATION
based on external pulses. Pulses fed to an
internal accumulator in the controller will be
compared to the setting entered by the
operator and will cause a sample cycle to
start. The accumulator will reset
immediately and counting of pulses will
begin again. There is no loss of count during
the sample cycle. Pulse requirements of the
system are detailed in the specifications.

Where external devices do not themselves
generate pulses in any relation to their
process but generate a current signal of
4-20mA, this input option will generate
internal pulses proportional to the incoming
4-20mA signal. These can then be treated
the same as the Pulse Input option and
accumulated in the controller to determine
when a sample cycle should occur.

The sampler controller can react to an
external dry contact, otherwise known as a
zero-voltage contact, to activate a sample
cycle on demand. This will generally be
when external conditions have caused a
relay to close, whose contact will cause a
sample to be taken.

5.4.2 SAMPLE INITIATION using Interval Time

The following sequence of entries are made
on the Touchpad to form a basic operating
parameter for operation of the sampler. This
will determine the time from the start of a
sample cycle to the start of the next sample
cycle. No time is lost during the actual
sample cycle. The ACTIVE SETTINGS are
not being altered.

1. Press the SET key.

2. Press the SAMPLE INITIATION key.

5-17

Section 5. Programming

3. Press an ARROW key. Continue until
Interval Time is shown on the display.

4. Press the ENTER key.

When setting the time, a flashing digit
prompts for input from a numeric key. To
set the time, press a numeric key to enter a
value and advance to each digit in
succession. The format is HHH:MM. The
minimum time can be set to 1 minute,
however, practical considerations, such as
equipment duty cycle, maintenance and
service life suggest times of 3 minutes or
longer.

When the five digits are entered, press
ENTER. Any wrong entries will require
re-entry. There are two methods of
correcting a mistake. The digit flashing
“wraps around” and begins again, at which
time the correct entry may be pressed.
Alternately, the arrow keys can be used to
reposition the flashing prompt over the error,
which can then be replaced with the correct
value.

5-18

The display will echo the last entry with
<ENTERED>.

The controller has now been given a new
value for SAMPLE INITIATION. The new
values reside in the NEW ENTRIES area of

5.5 Programming PROGRAM TYPE

5.5.1 PROGRAM TYPE Overview

PROGRAM TYPE is the function which determines how the sampler will
perform its program. A variety of options are available. These options are
programmable from the Touchpad and require only that the sampler have the
correct equipment configuration to utilize them. The basic function of the
Program Type is to determine the movement of the distributor.

The program option which determines that
all the samples that are gathered will be
placed in a single container. The sampler
program terminates after the specified
number of samples have been taken.

This option is used for discrete sampling
applications, to deposit one or a number of
samples to one container before advancing
to the next container. The interval between
samples is controlled by the SAMPLE
INITIATION function. The
multi-composite setting is programmable up
to 99 samples per container, for up to 24
containers depending on the hardware
configuration.

Section 5. Programming

This option is used for discrete sampling
applications, to successively deposit one
sample to each of a programmed number of
containers on any given sample initiation.
The consecutive setting is programmable up
to 99 containers per sample initiation.

Allows the sampler to deposit equal sample
volumes into a predetermined number of
containers per programmed day. Each day
may have any number of samples taken,
dependent on the SAMPLE INITIATION
mode chosen. Deposits are made to as many
as 9 containers per day, to a cumulative total
of 24 containers. Timing is dependent on the
crystal-controlled Real Time Clock in the
controller. The first program day will be the
current day the programming is done.

5-23

Section 5. Programming

5.5.2 PROGRAM TYPE - Composite

This option will cause the sampler to step to
a new container regardless of the status of
the SAMPLE INITIATION setting. For
example, the actual sampling may be under
the control of a flowmeter and taking
samples based on the flow rate as
determined by pulses or 4-20mA input to the
controller. When the user-programmed
timed interval has elapsed, the controller
will step to a new container. The Timed
Step can be set for any interval up to 99
hours 59 minutes. Progress of the step timer
can be viewed by selecting View, Program
Type and pressing ENTER twice. Thus you
may view the step timing and the amount of
time until the next step occurs.

The following sequence of entries are made
on the Touchpad to describe how the
Sampler controller is to store the samples it
takes, in the hardware specified in its
configuration. The ACTIVE SETTINGS are
not being altered.

1. Press the SET key.

2. Press the PROGRAM TYPE key.

3. Press an ARROW key. Continue until
Composite is shown on the display (for
storage in single container).

5.6 Programming OTHER OPTIONS

5.6.1 OTHER OPTIONS Overview

SET or VIEW

This feature allows the user to SET or
VIEW the internal Real-Time clock of the

microprocessor.

This feature allows the user to SET or
VIEW the duration for which the sampler
will purge the intake line prior to drawing in
a sample to the chamber. The maximum
allowable setting is 99 seconds.

This feature allows the user to change how
the pinch valve will operate during sampling
cycles. Depending on which generation of
sampler the controller is to be used on
determines the setting. If this is a new unit,
the pinch valve action will have been factory
set. Should the controller be used as a
retrofit into an older model, the setting may
have to be changed. If the sampler has a
pinch valve that squeezes shut the discharge
tube even during an inactive state, this
model is termed as normally closed. Should
the tubing be shut only when the pinch valve
is energized, it is termed normally open.

This is the ONLY setting for the
PVSsamplers.

This feature will enable or disable the ability
of the controller to cease operations when it
encounters repeated difficulties in the
drawing of samples. The controller normally
will attempt to obtain a valid sample by
repetition of its programming with extended
purge times and vacuum cycles, also
extending the time allowed for the
acquisition of the sample. When a sample is
not obtained, this fact is noted in the
controller memory and the program resumes.
If after two (2) successive attempts have
failed, the controller will Shut Down, halting
sampling until operator intervention clears
any reason for fault and RESTARTs the
program. This is not always a required
course of action. If FAULT SHUTDOWN is
disabled, the program will record all failures
to obtain samples and without further

attempts being made to obtain the failed
sample, will wait until the next sample
initiation.

The controller will remember conditions
encountered during normal operation.
Reasons for premature ending of a set
program will also be saved in memory. By
VIEWing this feature, this information can
be obtained at the time the sampler is
checked.

Values retained by the controller to indicate
number of missed samples.

When equipped with the appropriate
hardware and with the controller running the
proper program (i.e. Multi-Composite), the
current position of the distributor arm can be
determined by VIEWing this option. The
position information is relative to the
original position of the arm at the beginning
of the program start. Note: There is no

physical “Bottle 1”, any bottle can be
determined to be #1 at the beginning of a
sample program.

Appendix C. Programming 4-20mA for Flow Proportional Sampling

In order to use the 4-20mA interface with a PVS Sampler, calculations must be
made based on flow. The 4-20mA input is a signal that corresponds to the flow
meter’s output. 20mA is equal to the maximum flow, and 4mA is equal to the
minimum flow. The controller requires a number which reflects the maximum
flow going through the sampler.

The PVS Controller generates 100 pulses per minute internally at the
maximum flow. This number decreases with the amount of flow proportional
to the 4-20mA scale. The Controller requires the number of pulses at maximum
flow. In order to calculate this, use the following formula:

1. Calculate Q. Q = Average flow rate divided by the maximum flow rate.

Rate Flow Average

Q =

RateFlowMaximu

2. Calculate t.

t =

samplesbetween Volume

minuteper volumeAverage

t is the number of minutes per sample you would like for an average flow rate.
Either choose how long between samples you’d like for average flow, or
calculate based on volume above.

3. Multiply Q x t x 100 (100 pulses at max flow)

This is the number you will input into the Controller at the 4-20mA dialogue.

Example

You want to collect samples every 30 minutes. On average 175gal/min flows
by. Maximum is 300gal/min.

1. Calculate Q.
