DANGER —MANY HAZARDS ARE ASSOCIATED WITH INSTALLING, USING, MAINTAINING, AND WORKING ON
OR AROUND TRIPODS, TOWERS, AND ANY ATTACHMENTS TO TRIPODS AND TOWERS SUCH AS SENSORS,
CROSSARMS, ENCLOSURES, ANTENNAS, ETC. FAILURE TO PROPERLY AND COMPLETELY ASSEMBLE,
INSTALL, OPERATE, USE, AND MAINTAIN TRIPODS, TOWERS, AND ATTACHMENTS, AND FAILURE TO HEED
WARNINGS, INCREASES THE RISK OF DEATH, ACCIDENT, SERIOUS INJURY, PROPERTY DAMAGE, AND
PRODUCT FAILURE. TAKE ALL REASONABLE PRECAUTIONS TO AVOID THESE HAZARDS. CHECK WITH YOUR
ORGANIZATION'S SAFETY COORDINATOR (OR POLICY) FOR PROCEDURES AND REQUIRED PROTECTIVE
EQUIPMENT PRIOR TO PERFORMING ANY WORK.
Use tripods, towers, and attachments to tripods and towers only for purposes for which they are designed. Do not
exceed design limits. Be familiar and comply with all instructions provided in product manuals. Manuals are
available at www.campbellsci.eu or by telephoning [phone] (UK). You are responsible for conformance
with governing codes and regulations, including safety regulations, and the integrity and location of structures or land
to which towers, tripods, and any attachments are attached. Installation sites should be evaluated and approved by a
qualified engineer. If questions or concerns arise regarding installation, use, or maintenance of tripods, towers,
attachments, or electrical connections, consult with a licensed and qualified engineer or electrician.
General
•Prior to performing site or installation work, obtain required approvals and permits. Comply with all
governing structure-height regulations, such as those of the FAA in the USA.
•Use only qualified personnel for installation, use, and maintenance of tripods and towers, and any
attachments to tripods and towers. The use of licensed and qualified contractors is highly recommended.
•Read all applicable instructions carefully and understand procedures thoroughly before beginning work.
•Wear a hardhat and eye protection, and take other appropriate safety precautions while working on or
around tripods and towers.

precautions to secure tripod and tower sites from trespassers.
•Use only manufacturer recommended parts, materials, and tools.
Utility and Electrical
•You can be killed or sustain serious bodily injury if the tripod, tower, or attachments you are installing,
constructing, using, or maintaining, or a tool, stake, or anchor, come in contact with overhead or
underground utility lines.
•Maintain a distance of at least one-and-one-half times structure height, or 20 feet, or the distance
required by applicable law, whichever is greater, between overhead utility lines and the structure (tripod,
tower, attachments, or tools).
•Prior to performing site or installation work, inform all utility companies and have all underground utilities
marked.

PVS5120-Series Portable Samplers
1. Introduction
The PVS5120-series samplers are automatic liquid samplers for water and
wastewater applications. These samplers gather fluid automatically from a
variety of sources including containers, open channels, sewers, pipes, and any
open source of water. They are lightweight, portable, battery-powered water
samplers designed for reliable unattended sample collection.
The PVS5120-series portable samplers use the VSC100 controller that allows a
Modbus® RTU master, SDI-12 master device, simple pulse input, or Campbell
Scientific PakBus® datalogger to control and communicate with the water
sampler. The PVS5120 can also run in a time-controlled, stand-alone mode.
The PVS5120C is a composite sampler that deposits its water samples into one
9 L container; the PVS5120D is a discrete sampler that deposits its water
samples into 1 to 24 containers.
2. Precautions
•READ AND UNDERSTAND the Safety section at the front of this
manual.
•CAUTION: Damage resulting from running the sampler under freezing
conditions will not be covered under the product warranty.
•Wiring to remote/external sensors 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.
•The intake hose should be 7.6 m (25 ft) or longer. Shorter hoses do not
provide sufficient back pressure to the metering chamber, allowing the
pump to efficiently expel all solids into the sample container.
•The liquid sensing rod and the volume control tube must be kept clean to
ensure the conductivity necessary to detect the presence of the fluid.
•CAUTION: Do not program the sampler using the generic SDI-12 sensor
option in Campbell Scientific’s Short Cut. The wiring diagram generated
by Short Cut is incorrect for connecting the PVS5120 to a datalogger. It
shows a power wire (12 V) connection that is not necessary for running the
sampler as an SDI-12 sensor. Connecting the control cable’s red wire to
the datalogger’s 12 V terminal causes problems in the sampler. See
Section 8.2.3, SDI-12 Control (p. 32), for more information.

3. Initial Inspection
•Upon receipt of the sampler, inspect the packaging and contents for
damage. File damage claims with the shipping company.
•Immediately check package contents against the shipping documentation.
Contact Campbell Scientific about any discrepancies.
4. Overview
The PVS5120-series can have a standard or a large pump. At sea level, the
standard pump takes samples at 1.6 m/s (5.1 ft/s) for horizontal draws of 7.6 m
(25 ft), and the large pump takes samples at 2.2 m/s (7.1 ft/s) at 7.6 m (25 ft).
When sampling is initiated, liquid travels through the intake hose to the volume
control 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 ±2 ml.
Sample accuracy increases when you have set the volume control rod and
tested the collected sample at setup. Once the pre-set amount has been
reached, all excess liquid is purged from the system, and the sample is dropped
into a container.

4.1.1.1 Manual Control Button
The blue Manual Control button is located at the top right of the control panel.
This button allows the user to Service the sampler, collect a Manual Sample, or
run the Auto Deploy routine. A label on top of the sampler shows the button’s
function (FIGURE 4-3).
FIGURE 4-3. Manual Control Button

PVS5120-Series Portable Samplers

1. Service the sampler: Push the button once and release. Servicing the
sampler tells the controller to zero all the sample counts and return to the
first bottle or home position. It assumes the user has emptied or replaced
the bottles. The next sample collected and logged by the datalogger is
bottle 1, sample number 1.
2. Manual Sample collection: Push the button twice and release. This
directs the sampler to collect a manual sample into whichever bottle the
sampler is currently on independent of the datalogger. This sample is
logged by the controller. The next time the datalogger tells the sampler to
collect a sample, the count increments by two.
For example, if the sampler is collecting only one sampler per bottle and it
is on bottle two, the manual sample drops in bottle 2 and the arm moves to
bottle 3. The next time the datalogger initiates a sample, the sampler
deposits it into bottle 3. The controller then returns to the datalogger the
following status values: bottle 3, sample 1, response code 0, and the
sampler battery voltage.
3. Auto Deploy routine: Push and hold the button until the sampler begins
running and then release the button. The Auto Deploy routine runs the
sampler through an entire sampling sequence while keeping track of the
time to move water from the water source to the metering chamber. It uses
this information to set the purge and the vacuum times within the
controller. The user can see these times and keep them or change them by
connecting to the VSC100 with our Device Configuration Utility
(DevConfig).
4.2 Composite and Discrete Overview
4.2.1 Discrete Sampling
The PVS5120D is a discrete system that places samples into more than one
container. It has a stepper assembly that moves a distributor arm. The
distributor arm revolves 360° and can deliver samples into 24 separate
containers. An encoder senses the distributor arm position. The PVS5120D
samplers can have 500 mL or 1 L bottles (FIGURE 4-1). Available bottle
configurations are 1, 2, 3, 4, 6, 8, 12, and 24.
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 sampling.
4.2.2 Composite Sampling
The PVS5120C composite sampler draws water samples into one 9 L container
(FIGURE 4-4). Composite sampling is the simplest method for taking samples
and is often used when the sampler is measuring effluent in one location. The
composite sampler is also less expensive than the discrete model.
