Precautions

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.com or
by telephoning [phone] (USA). 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.

• Do not climb tripods or towers at any time, and prohibit climbing by other persons. Take

reasonable 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, 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.

• Comply with all electrical codes. Electrical equipment and related grounding devices should

be installed by a licensed and qualified electrician.

Elevated Work and Weather

• Exercise extreme caution when performing elevated work.

• Use appropriate equipment and safety practices.

• During installation and maintenance, keep tower and tripod sites clear of un-trained or non-

essential personnel. Take precautions to prevent elevated tools and objects from dropping.

• Do not perform any work in inclement weather, including wind, rain, snow, lightning, etc.

Maintenance

• Periodically (at least yearly) check for wear and damage, including corrosion, stress cracks,

frayed cables, loose cable clamps, cable tightness, etc. and take necessary corrective actions.

• Periodically (at least yearly) check electrical ground connections.

WHILE EVERY ATTEMPT IS MADE TO EMBODY THE HIGHEST DEGREE OF SAFETY IN ALL CAMPBELL SCIENTIFIC PRODUCTS,
THE CUSTOMER ASSUMES ALL RISK FROM ANY INJURY RESULTING FROM IMPROPER INSTALLATION, USE, OR
MAINTENANCE OF TRIPODS, TOWERS, OR ATTACHMENTS TO TRIPODS AND TOWERS SUCH AS SENSORS, CROSSARMS,
ENCLOSURES, ANTENNAS, ETC.

CS470/CS471 Compact Bubbler System

1. Introduction

The CS470 and CS471 are designed for general liquid level measurements.
They use SDI-12 or RS-232 communications protocols to communicate with a
SDI-12 or RS-232 recorder simplifying installation and programming.

2. Cautionary Statements

• READ AND UNDERSTAND the Precautions section at the front of this

manual.

• Remember that although the CS470/CS471 is designed to be a rugged and

reliable device for field use, it is also a highly precise scientific instrument
and should be handled as such.

• NEVER open the housing of the CS470/CS471. There are no user-

serviceable parts inside the sensor housing and any attempt to disassemble
the device will void the warranty.

• While connecting the tubing, keep contamination or moisture from

entering the tubing.

• Do not damage or kink the tubing during installation.

• Always use a sharp knife instead of scissors to cut the tubing.

3. Initial Inspection

• Upon receipt of the CS470/CS471, inspect the packaging for any signs of

shipping damage, and, if found, report the damage to the carrier in
accordance with policy. The contents of the package should also be
inspected and a claim filed if any shipping related damage is discovered.

• Care should be taken when opening the package not to damage or cut the

polyethylene tubing (if ordered). If there is any question about damage
having been caused to the tubing, a thorough inspection is prudent.

• The model number and serial number is printed on the housing. Check

this information against the shipping documentation to ensure that the
expected model number was received.

• Refer to Section 3.1, Shipping Kit and Accessories, to ensure you have all

of the components

adapter allows the bubble chamber to be connected to standard
plumbing materials.

4. Quickstart

Short Cut is an easy way to program your datalogger to measure the sensor and
assign datalogger wiring terminals. The following procedure shows using
Short Cut to program the CS470/CS471.

1. Install Short Cut by clicking on the install file icon. Get the install file

from either www.campbellsci.com, the ResourceDVD, or find it in
installations of LoggerNet, PC200W, PC400, or RTDAQ software.

2. The Short Cut installation should place a Short Cut icon on the desktop of

your computer. To open Short Cut, click on this icon.

3. When Short Cut opens, select New Program.

4. Select Datalogger Model and Scan Interval (60 second or higher scan

interval is recommended). Click Next.

CS470/CS471 Compact Bubbler System

5. Under the Available Sensors and Devices list, select the Sensors |

Generic Measurements folder. Select SDI-12 Sensor, click to move

the selection to the Selected device window. Enter the result names and
units. The default SDI-12 address is 0 and the default SDI-12 command is
aM!. The SDI-12 address should only be changed from the default when
more than one sensor is connected to the same datalogger channel. The
SDI-12 command can be changed by clicking the SDI-12 Command box
and selecting one of the other options.

6. After selecting the sensor, click at the left of the screen on Wiring

Diagram to see how the sensor is to be wired to the datalogger. The
wiring diagram can be printed out now or after more sensors are added.
