2 SAFETY INSTRUCTIONS
2.1 Types of Notices
Throughout this manual you will find various types of safety
notices. Their meanings are defined as:
Warning –Indicates the possibility of a hazardous situation which,
if not avoided, could result in injury or substantial property
damage.
Caution –Indicates the possibility of a hazardous situation which, if
not avoided, may result in minor injury or damage to the
equipment, or property.
Note –Emphasizes points, reminds you of something, or indicates
minor problems in the outcome of what you are doing.
2.2 General Safety Guidelines
CAUTION
Do not attempt to operate the Resonator with damaged or suspect vessels.
Note: Changes in noise level or frequency are common during
mixing operations. If you experience rattling, metal-on-metal, or
obnoxious noises, turn off the machine and examine equipment for
the cause.
WARNING
Do not attempt to override the SAFETY INTERLOCK SWITCH located on the Top Ring
of the Resonator. During operation, the Resonator Top Plate, Fixture, and Vessel,
vibrate up to 100 G’s. Serious bodily injury can occur if you come in contact with these
moving surfaces.

3 DEFINITIONS
RAM. ResonantAcoustic®Mixing
SMT. Smart Mixing Technology; closed loop resonance tracking
where the Power / Control Supply senses feedback from the mixer
and controls the resonant response.
RAMWare. Control software that runs on a Personal Computer
(P.C.) and provides control to, and feedback from, the mixing
process.
Damping. A measure of the instantaneous amount of energy
absorbed by your mix media while mixing.
Resonance. The point at which the system vibrates in the most
efficient manner.
Mix Media. A volume of fluid, powder, emulsion, or combination
thereof.
Mixing Regime. A description that identifies certain modes of
mixing. For example, a fluid will change regimes as it undergoes
acceleration, from an incompressible liquid with few headspace
bubbles in it, to a fluid that is fully integrated with the compressible
headspace such that the two are indistinguishable from each other.
Headspace. The volume of compressible air or gas space, above
the fluid in the vessel, that is un-occupied by the fluid.
G’s. A measure of acceleration expressed as a multiple of the
gravitational acceleration applied to the vessel and mix media
during mixing. For example, 10 G’s is 10 times the force of gravity.
Acceleration. A change in velocity with respect to time. Your mix
media mixes at different accelerations that are expressed in G’s.

Intensity. A non-dimensional unit of Driver energy applied to the
Resonator.
Vacuum. Some pressure less than atmospheric.
4 INTRODUCTION TO THE LabRAM
Your LabRAM mixer is based on Resodyn Corporation’s
ResonantAcoustic®Mixing (RAM) technology. RAM mixing is
distinctly different than conventional mixing methods such as
impeller agitation. Conventional methods work by producing bulk
fluid flow in a mixture. RAM brings to you a new paradigm in
mixing that is based on using acoustic energy to create flow in
liquids, slurries, and powders.
At the heart of your new RAM mixer is a resonant mechanical
system. The system creates high-intensity, low-frequency acoustic
waves in your mixing vessel that result in mixing.
This manual will provide you with the knowledge necessary to:
Understand the major components of your LabRAM
Introduce you to the theory of RAM mixing
Set up the LabRAM equipment
Operate the equipment
Trouble shoot common problems
Clean and maintain the equipment
Attach custom vessel fixtures and power requirements
Get your equipment serviced
Obtain additional accessories
Not covered in this manual are:
Repair of the mixer
Use of RAMWare
Note: RAMWare is a software package that runs on a P.C. and is
networked to the LabRAM. It is used to control multiple RAM units,
collect data and store mixing profiles. A separate user manual
describes the use of RAMWare.

5 MAJOR COMPONENTS
5.1 Overall Assembly
The overall assembly comprises: the Resonator, Cover, Umbilical
Cables and Power Supply.
Note: An optional Vessel Hold-down Fixture and a variety of vessel
sizes are available from Resodyn Acoustic Mixers; see the
ACCESSORIES Section 14 at the end of this Manual.

5.2 Resonator
The Resonator is the primary driver in your RAM mixer system.
Your vessel, containing your mix media, attaches to the Top Plate.
The Resonator, a powerful unit in a small package, works in a
resonant mode to provide efficient energy transfer to the mix media
in your vessel. Precise control over different mixing profiles is
provided through the user interface panel on the front of the unit.
Additional control, and feedback from your process, is available
using RAMWare software and a P.C.
CAUTION
The Resonator weighs approximately 130
lbs. The Lab Bench must be capable of
solidly supporting the Resonator. Use
care when moving.

Cover. The Cover is cast acrylic. Its purpose is to contain fluid and
debris if a vessel breaks during operation. A second purpose is to
prevent a person from touching moving parts while the mixer is
operating. It activates the safety interlock switch. The mixer will
not operate without the interlock switch activated and the Cover in
place.
User Interface. The User Interface is a membrane keypad with a
clear window revealing a Liquid Crystal Display (LCD). The LCD is
used to display the operating status of your mixer. The keypad is
used to start and stop the machine, and input operating parameters
such as Driver intensity and Frequency.
Power Switch. The Power Switch cycles power to the Resonator. It
is redundant to the power switch on the back of the power supply.
So, you may leave the power supply on continuously and turn
power on and off at the Resonator using this switch. Note: Both
power switches must be in the ON position for the machine to
operate.
Safety Interlock Switch. The Safety Interlock Switch prevents you
from operating the machine without the cover in place. When the
cover is installed properly, it depresses the Safety Interlock Switch
allowing the machine to run.
Enclosure. The Enclosure protects you from moving parts inside
the machine.
Input/Output Connectors. The Input/Output Connectors are used
with a cable harness to connect power and transmit signals
between the Resonator and the Power Supply. The Power
connector holds 7 pins; the I/O connector holds 16 pins.
Leveler Feet. The Leveler Feet may be adjusted to level the
Resonator Top Plate. They also provide additional vibration
isolation to your work bench.

5.3 Power Supply and Control
The Power Supply and Control is separate from the Resonator and
can be located remotely, in order to minimize space occupied on
your lab bench. The Power Supply provides power to the
Resonator. It is connected to the Resonator through two cable
harnesses and has its own power switch. Using precise closed
loop controls, The Power Supply also automatically holds the
Resonator in resonance while mixing.
CAUTION
The Power supply weighs
approximately 40 lbs and must be
located in a secure area away from
potential liquid spills.
CAUTION
The Power supply operates at 115
VAC, 15 amps, 50 to 60 Hz.

Main Power Switch. The Main Power Switch cycles power from the
A.C. Power Entry socket. The switch may be left ON continuously.
Power may then be switched ON or OFF at the Resonator switch.
Note: Both power switches must be in the ON position for the
machine to operate.
Resonator Fuse Holder. This holds a 10 amp, slow blow fuse, 3 Ag,
250 V.
Main Fuse Holder. This holds a 15 amp, slow blow fuse, 3Ag, 250
V.
A.C. Power Entry. This is a standard A.C. Power Entry socket. It is
rated for 115 VAC, 15 amps, 50 Hz to 60 Hz.
RS-232 Connector. This is a standard RS-232 port. It is used to
connect your mixer to a PC. RamWARE software, used on your PC,
is available to monitor and control your mix process from the PC.
Resonator Power Connector. This is a 7 pin connector. It is used
with a cable harness to connect power from the Power Supply to
the Resonator.
Resonator I/O Connector. This is a 16 pin connector. It is used
with a cable harness to connect I/O data between the Resonator
and the Power Supply.
