2.1 Overview of Digital Sonifier
The 250/450 Digital Sonifier is often used by laboratory personnel in the medical and chemical
process fields. The system consists of three core elements: the power supply, the controls, and
the converter and horn. The system can interface with customer equipment including a remote
computer or terminal, dot matrix printer, temperature probe, and User I/O.

Introduction to the Digital Sonifier
The 250 and 450 Digital Sonifiers differ only in their output power ratings, measured when the
output control is at maximum setting. The 250’s maximum available output power is up to 200
watts; the 450’s maximum available output power is up to 400 watts.
The digital controls on the Digital Sonifier allow for accuracy and repeatability of control set-
tings. You enter application parameters into the system either through the keypad on the front
panel of the unit, or remotely through a computer keyboard, and can save up to twenty (20)
sets of preset control parameters. You can view operating parameters through the twenty-char-
acter, four-line LCD display on the unit control panel and on a remote terminal if one is con-
nected. At System Setup, you can select a language for the display: English, German, French,
Italian, or Spanish.
The Digital Sonifier’s power supply converts AC line voltage to 20kHz electrical energy. This
high-frequency electrical energy is fed to a converter where it is converted to mechanical vibra-
tions. The heart of the converter is a lead zirconate titanate electrostrictive element which,
when subjected to an alternating voltage, expands and contracts. The converter vibrates in a
longitudinal direction and transmits this motion to the horn tip immersed in the solution,
which causes cavitation. The implosion of microscopic cavities in the solution results, causing
the molecules in the medium to become intensely agitated. The ultrasonic vibrations transmit-
ted through the horn can also be applied directly to a solid workpiece, such as tissue, through
a variety of different tips that can be attached to the horn.
The Digital Sonifier is a constant amplitude device. As the load or pressure on the horn face
increases, the power supply develops more power to maintain the amplitude for any given out-
put control setting. When the horn is operated in air, it is subjected to minimum pressure, and
minimum power is required to maintain amplitude.
The load increases when the horn is immersed in a liquid; the more viscous the liquid, the
higher the load and the more power developed. If a flow-through cell that can be pressurized
is used, thereby increasing pressure on the horn, even more power is developed. For any given
application, more power results when a horn of higher amplitude or larger radiating surface is
used, or when any horn is driven at higher amplitude by increasing the amplitude.
By setting various operation parameters, you can precisely control the way in which ultrasonics
are applied to the sample. You can:
• Specify the time duration of the experiment
• Adjust the amplitude setting between 10% and 100% of maximum amplitude
(microtip 70% maximum)
• Prevent excessive temperature increase in the sample by setting ultrasonics to
operate in Pulse m ode or in Pulse/Pause mode
• Bring a sample to a desired temperature an d hold it there, v ary ing by only a few
degrees, for a d es ired duration using the Pulse/Paus e mode
• Set the maximum allowable temperature in t he sample, so that ultrasonics will
stop automatically when the specified temperature is reac hed

Installation and Setup
CAUTION
j DO NOT allow the horn or microtip to contact lab stands, beakers, test tubes
or simil ar objects. Microtip failure may result. Breakage of glassware may
result in the loss of a specimen.
Disruptor horns are the base for many microtip applications. Disrupter horns are threaded so
that they may also be inserted into a Flow-Thru chamber attachment (see page 4-6). When
threaded together, a closed chamber is formed between the Tissue Disruptor and the cavity of
the Flow-Thru Attachment. The Tissue Disruptor may also be used alone.
The Tapered Microtip attaches directly to a standard 1/2 inch tapped Disruptor horn. The
amplitu de at the end of a tap ered tip is thr ee and one- hal f times g re ate r tha n tha t of the sta n-
dard horn. The tapered tip is recommended for difficult applications such as spores, fungi,
yeast, muscle, and connective tissue. Excellent results can be achieved on volumes ranging
from 3 to 20 ml in a comparatively short period of time. The diameters of the tapered micro
tips are 1/8 inch (3.2 mm), 3/16 inch (4.8 mm), and 1/4 inch (6.4 mm).
The stepped microtip is a two-piece unit, consis ti ng of a Coupling Section and a lower double-
step tip. Because the coupling section is attached directly to the converter, the standard disrup-
tor horn must be removed prior to using the stepped microtip. Recommended for use on
extremely small volumes, the stepped microtip can be used to treat volumes ranging from 0.5
to 20 ml. Applications for this tip include red and white blood cells, tissue culture cells, HeLa
cells, and the complete range of cells that have low to medium resistance to breakage.
To prevent foaming or aerosoling while processing small quantities with the tapered or stepped
microtips, the us e of a conical-sh ap ed tube s uch as a reaction vial or a cut down centrifuge tube
is recommended.
CAUTION
j When u sing microtips, do not exceed a maximum Amplitude Control setting
of 70%. The microtip will break if driven at higher amplitu des .
Tissue Disruptor
Designed for disintegration of difficult tissues, this stainless steel accessory has a specially con-
structed cell bottom that holds up to six grams of tissue. A water jacket may be provided for
cooling.

System Component Desc ription
Digital Sonifier
Cup Horn
Cup Horns allow materials to be treated in small vials or test tubes without immersing the
ultrasonic horn or micro tip in the material, thereby providing completely sterile conditions. A
Cup Horn is attached directly to the converter, and the assembly is mounted upside-down on
the lab stand with the Cup Horn at the top. With chilled water in the Cup Horn, test tubes are
suspended in the Cup with the contents of the tubes just below the water level. Ultrasonic
energy is then conducted from the surface of the horn, through the water and test tube walls,
to the contents of the tube.
Some energy loss may occur when applying ultrasonics in this indirect way, and processing can
take longer than if the ultrasonic horn were immersed directly in the solution.
There are two types of Cup Horn, a high intensity unit that will accommodate a single test tube,
and a larger unit for multiple test tubes. The high intensity Cup Horn has a concave bottom
that focuses the ultrasonic energy on the bottom of the tube. The larger unit, with a diameter
of two or three inches, allows the immersion of multiple test tubes. The larger Cup Horns have
clear plastic walls, which permit easy viewing of the activity in the tubes during processing.
Both types of Cup Horn are designed to allow chilled water to circulate through the cup to
prevent heating of the solution as a result of the ultrasonic activity.
CAUTION
j The bottom of the t es t tubes should not be in contact with the surface of the
ultrasonic horn. Such contact c ould caus e break age and loss of samp le.

Installation and Setup
Flow-Thru Horn
The Flow-Thru Horn has two inputs or orifices at the non-vibrating, nodal point of the horn.
A pre-mixed substance is fed through one of the inputs while the horn is ultrasonically acti-
vated. Because two inputs are available, two different types of material can be treated simulta-
neously for mixing or emulsifying. The processed solution exits at the tip of the horn. The horn
can be used as a continuous-flow device to collect the solution in one large vessel.

System Component Desc ription
Digital Sonifier
This attachment, which is screwed onto the disruptor horn, permits continuous processing of
low-viscosity materials at rates of up to 38 liters per hour. Designed primarily for emulsifying,
dispersing, and homogenizing, the attachment will disrupt most cells, with the exception of the
more difficult species. The materials being treated can be passed through the attachment more
than once to obtain desired results. For cooling, a water jacket with input, output, and overflow
connections is provided.
Rosett Cell
The Rosett Cell, made of borosilicate glass, has a conical shape with three side arms, through
which the solution is driven by pressure produced from vibrations from the ultrasonic horn,
thereby exposing the substance to ultrasonic energy repeatedly during circulation. When the
Rosett Cell is immersed in a cooling bath, the enlarged glass surface area and circulation
through the side arms provide an efficient means of heat exchange.
The Rosett Cell is available in three sizes: 8-25 ml, 25-180 ml, and 35-300 ml.
Flow-Thru Rosett Cell
The Flow-Thru Rosett Cell is equipped with its own water cooling jacket, with intake and out-
put connections for continuous processing and a double chamber for cooling. Normally, ade-
quate cooling can be achieved by connection to the cold water tap or by using a closed circuit
system. An ice/salt water solution will maintain a temperature below 0
°
C. Since the double
chamber is made of glass, the substance can be easily observed during treatment. The Flow-
Thru Rosett Cell is not suited for difficult cells.

Installation and Setup
Soundproof Enclosure
Although ultrasound is above the normal range of human hearing, audible sound sometimes
occurs when liquids are treated ultrasonically, especially due to cavitation produced by ultra-
sonic vibration. The Soundproof Enclosure can be used to reduce this to an acceptable level.
It is especially useful when the Sonifier is used for extended periods of time.
The Soundproof Enclosure is also useful at minimizing splashing while the experiment is run-
ning. Cooling within the enclosure may be required for certain applications. Detail of the enclo-
sure may vary from those depicted below.

Installation and Setup
4.4.2 Connecting Tips, Horns, and Converters
Connecting the Horn to the Converter
To connect the horn to the converter, take the following steps:
A standard flat tip, recommended for processing liquids, is supplied with tapped horns. Other
tip configurations are available for experimental work on applications where the ultrasonic
vibrations are transmitted directly into the solution. The shape of the horn influences the direc-
tion in which the ultrasonic vibrations are delivered from the horn.
Connecting the Tip to the Horn
To attach the tip to the horn, take the following steps:
Step Action
1
Clean the c onta cting surfaces of the converter and horn, and remove any
foreign matter f rom the threa ded stud and threaded hole.
2
Coat one of the mating surfaces completely with a very thin film of silicone
grease (without additives), using an amou nt about the size of a paper
match head. Excessive silicone grease can diminish performance.
3
Thread t he horn stud into the converter and tighten, using spanner
wrenches. The recommended torque is 220 inch-pounds (24.85 Nm).
Step Action
1
Clean contacting surfa ce s of the horn and tip, and remove any foreign
matter fr om the threa ded stud and threaded hole.
CAUTION
j The t ip must be installed clean and dry, or the po wer supp ly
may not tune and operate correctly.
2
Hand-assemble the t ip to the horn.

Although the Digital Sonifier operates outside the normal range of human hearing, some appli-
cations can create audible noise above 85dB. If an uncomfortable level of noise is present, the
operator should wear ear protection for safe operation.
Appropriate eye protection should be worn when operating the Digital Sonifier, to prevent
possible splash injury originating in the solution.
WARNING
j TheUltrasonic Horn can cause injury and/or equipment damage during op er-
ation. To avoid injury or a cci dent, never touch the Ultrasonic Horn while the
System is t urned on, and do not allow the Horn to come in contact with solid
vessels or s upports.
The User I/O may be used to remotely control the System. If this is the case, you must design

WARNING
j Do NOT t ouc h the vibrating horn, or place the vibrating horn against solid objects such as
beakers and cruc ibles. Touchingor ho lding the horn can result in burns or injury,a nd contacting solid mat erials with the vibrating horn or tip can cause breakage.
CAUTION
j DO NOT run t he microtip above an Amplitude setting of 70%. Doing so can cause dam age
to the microtip assembly.
System Modes
You can control the way in which ultrasonics are applied to your sample by setting the unit to operate in one of
several different modes. You determine the mode in which to operate by specifying parameters for your exper-
iment. There are five system modes, as described below:
• Continuous Mode: Ultrasonics are applied to the sample until you Stop or Pause the experiment.
• Timed Mode: Ultrasonics are applied to the sample for a period of time that you specify by setting the
Time parameter.
• Pulse Mode: Ultrasonics are turned on and off repeatedly during the experiment. Youspecify the length
of the interva ls in which ultrasonics are on and off. F or example, y ou can specify 0.5 seconds for the
Pulse On parameter and 2.1 seconds for the Pulse Off parameter. You c an also specify a time limit us ing
the Time parameter, and/ or a temperature limit using the Temperature parameter.
• Temperature Mo de: Ultrasonics are ap plied until the sample rea ch es a temperature that y ou specify by
setting t he Temperature parameter. The Temperature Mode requires the optional Temperat ure Probe,
and operates as f ollows:
• when no TIME or PULSE TEMP parameter is entered, the experiment stops wh en the MAX
TEMP value has been reached.
• When a TIME and MAX TEMP value have been entered , the experiment ru ns until the TIME has
elapsed. If the MAX TEMP is reached before the TIME parameter has elapsed, ultrasonic vibra tions will temporarily stop (and the timer will stop counting) until the Probe Temperature has
dropped by 3 degrees below the MAX TEMP setting, at which point the timer and the ultrasonic
vibrations resume. The front panel displa y shows the prope r ultrasonics active displays.
• Pulse/Pause Mode:Used for holding an experiment withina desired temperature range. Ultrasonics are
applied to t he sample while keeping the sampl e’s temperature between the Pulse Temperature value
and the Max imum Temperature values that you specify. This allows you to limit temperature buildup in
the sample w hile continuing ultrasonic treatment until you obtain the proc es s results that you want.
Page 50
100-214-239 Rev. A 6-3
Setup and Operation
Digital Sonifier
Pulse/Pause Process Cycle
In Pulse/Pause Mode, the system applies ultrasonics (either Pulsed or not) to the sample until it reaches the
Pulse Temperature. The system then adjusts (or sets) the Pulse On/Pulse Off times for this continuing process,
in order to slow the heating process of the sample. When the experiment reaches the Maximum Temperature,
ultrasonics are turned off temporarily until the sample’s temperature drops three degrees (either Celsius or Fahr-
enheit), at which point ultrasonic treatment resumes, using the Pulse On-time/Pulse Off-time ratio calculated
by the system, until the Maximum Temperature is reached and ultrasonics are once again turned off. This pro-
cess is repeated until you manually stop the experiment or until the Time that you specified as a limit has elapsed.
While the experiment is running, the current and Maximum Temperatures are displayed and updated every sec-
ond.
Limits
You may wish to set a Time or Temperature value as a Limit for some experiments. This will cause the experi-
ment cycle to Stop if either the indicated Time has elapsed or the maximum T emperature was reached. If a Limit
is not desired, the parameter should be set to OFF.

Operation
The following chart summarizes the System Mode options, including the use of Limits:
NOTE
i You must hav e a Temperature Probe attached to the un it to use the Temperature Mode, the
Pulse/Pause Mode, or to use Temperature as a Limit.
System States
Availability of the Digital Sonifier’s functions depends on the system state. The ‘normal’ state of the system for
most users is the Run or Ready mode. Some remote terminal commands are noted where appropriate (com-
mands have the format of an ‘!’ followed by upper-case letter or letters, i.e. !TS for the Test command). These
commands are also summarized in the Remote Terminal section found on page 6-35. The possible system states
include:
• Power-Up:The system enters the Power-Up state when the power switch is turned on. The fan starts to
run, and the system then enters the Self-Diagnostics state.
• Self-Diagnostics: In this state, the system performs hardware and software checks on itself. The front
panel display shows several diagn ostic displays (indicating which step in the self-diagnostics it is in) and
the front panel LEDs will illuminate as a visible test. After it successfully completes this system check, it
enters t he Ready state.
• Ready: In t he Ready state, the system is waiting to begin an experiment, and it can accept parameter
settings that y ou ent er through the keypad or the remote computer or terminal. The front panel display

• Run: After s et ti ng parame ters for y our application, pressing the Start/Stop button or sending a !ON command will Startyour setup. Ultrasonic p ower is delivered to the horn (whether continuous or pulsed), and
the front panel display will show the runtime information, including the perc entage of power used on its
bottom line as a bargraph display, and the LED next to the Start/St op button rem ains lit while the application is runni ng. If you set Limits, your application will Stop automatica lly upon reaching thos e limits.
• Test: From t he Ready state, the system enters the Test state when you press the Tes t key or issue a !TS
command to enter the Test state, causing ultrasonics to be sent to the horn. After two seconds, the system returns to the Ready state.
• Print: If you have a printer connected, and after running a cycle or testing the setup you may print a
report of your experiment. Printing is started by pressing the Print/Send key or sending a !P comma nd.
After printing, the system returns to the Ready state.
• Report: If you are using the Remote Terminal option, and after running a cycle or testing the set up, you
may se nd a report of your experiment from the system to your terminal. After the report is sent, the system returns to the Ready state.
• Hold/Pause:When you press the Hold/Pause key or issue an !Hcommand during an experim ent ortest ,
the system stops operating, stops all timer functions, and enters the Hold/Pause state. To resume operation, press the Hold/Pause key again, or issue another !H command.
• Stop/Abort: When you p ress the Start/Stop button or issue an !OFF command, the system enters th e
Stop/Abort state. The experiment or test is stop ped.
6.2 Front Panel Controls
The membrane keypad on the front panel of the Digital Sonifier allows you to enter parameters for both
System
Setup
and
Operation
of the unit during a test or experiment. You can also use a remote computer or terminal to
enter operation parameters. If a remote computer or terminal is enabled, you can lock out the keypad on the
front panel of the unit if you want to operate the unit only from the remote computer or terminal. When the
keypad is disabled through the remote computer or terminal, all keys except the Start/Stop key and the Pause
key are disabled.
There are two additional controls (Amplitude Control and Power Switch) which work with the front panel con-
trols, but are not actually part of the front panel. The remote computer or terminal may be used to control the
system as well.
6.2.1 Power Switch
The Power switch for the system is located on the front of the unit, underneath the front panel controls. It is a
simple rocker switch, on/off operation. When turned on, the front panel LEDs will light (during the power-up
sequence), and the unit’s fan will run.

Operation
6.2.2 Temperature Probe
The optional Temperature Probe is required for the Temperature Mode, the Pulse/Pause Mode, or to use Tem-
perature as a Limit for your experiment.
6.2.3 Remote Terminal
An optional ‘Remote Terminal’ device may be used to setup and to run the experiment. The remote device can
fully control the Digital Sonifier using the built-in serial interface. Instructions for using the remote computer
or terminal and the Remote T erminal commands that you can use to enter parameters from your remote com-
puter or remote terminal are described in
Section 6.5, Remote Computer or Terminal,
beginning on page 6-35.
NOTE
i ‘Remote Terminal’commands apply to a R emote Computer or a Remote Terminal. The Setup
commands only indicate ‘Remote Terminal’ for simplicity.
6.2.4 Amplitude Control
The Amplitude control is found on the right side of the system chassis, it is a large circular control protruding
through the side of the Front Panel. It rotates up and down to regulate the Amplitude value from minimum to
maximum. The Amplitude value is displayed on the Front Panel display.
The Amplitude is displayed numerically on the bottom line of the Ready display in 1% units (to a system max-
imum of 100%), and after an experiment has been run. Amplitude may be adjusted while an experiment is run-
ning. An example of the Amplitude numerical display is shown in Figure 6.1 on page 6-7.
When the system is running, the Amplitude of the ultrasonic energy is displayed on the bottom line of the first
page of the runtime display as a bargraph, in 5% increments. An example of the bargraph display is shown in
Section 6.8, Displays During the Experiment
, on page 6-44.

6.4 Entering Operation Parameters
You can enter Operation parameters through the keypad or through the remote terminal, if the terminal is
enabled in the System Setup menu. Only the Amplitude value (using the Amplitude knob on the side of the
chassis) may be changed when an experiment is running.
When the System is in the Ready mode (e.g. after power-up or after a test or experiment is performed) it displays
the first page of the Parameter Entry menu. In the Parameter Entry menu, you can enter parameters for your
test or experiment. When a Line Select key for a parameter is available and may be selected, its LED is lit.
Entering Parameters from the Keypad
When in the Ready mode, you can press any available
Line Select
key on the front panel to select a parameter
for modification. There are a total of two (2) pages of parameters; use the Arrow Up or Arrow Down keys to
see more parameter choices on the display.
Use the number keys to key in a parameter value, and press
Enter
to store the value or accept the choice, or
press
Clear
to clear a stored numeric entry or to disable a choice and then press
Enter
to store the cleared or
disabled parameter value. The System will not accept parameter values that are out of the range of the system.
Once the parameters have been changed and stored, the experiment is ready to run with the new values.
6.4.1 Presets
Once you have a set of parameters stored for a given experiment, you can save that setup as a Preset. Up to 20
Presets may be saved, using the Save and Recall functions described in the following sections. Presets are saved
and recalled using a number, 01 to 20. Presets save all parameters for the setup except for the Amplitude param-
eter. Presets are saved until they are over-written or cleared, and are maintained in memory even if the system
is turned off or unplugged.
6.4.2 Remote Terminal entry
The Remote Terminal may be used to change any of the operation parameters (except for Amplitude). Instruc-
tions and commands that you use to enter parameters from the remote terminal are described in
Section 6.5,
Remote Computer or Terminal,
beginning on page 6-35.
Reviewing Parameters on the Remote Terminal
If you have disabled the front-panel keypad by sending a !KL from the remote terminal, only the
Start/Stop
and
Pause
keys are active. If both the keypad and the remote computer or terminal are active, the parameters
displayed on the front panel will be similar to those described in this section, but any values you enter on the
keypad will be updated at the remote computer or terminal only when you request them by issuing the Recall
Parameters (!RP) command. See
Section 6.5, Remote Computer or Terminal,
beginning on page 6-35 for more infor-
mation.

7.1 Maintenance and Troubleshooting
The Digital Sonifier is a self-contained system that requires no internal servicing, except for a
protective fuse, and there are no user serviceable parts inside the unit. The ultrasonic tooling
(horns and tips) may require periodic inspection and maintenance to ensure optimum perfor-
mance. T h e tooling components are subj ect to wear and may require re pl ac ement after a period
of time, depending on the applications.
If you have a problem operating your unit, refer to Table 1:
’System Trouble Analysis Chart’
on
page 7-7 to locate the symptom that most clearly describes your problem.
Tip Erosion
Horn tips can erode. Tip erosion is a side effect of the cavitation process that occurs when liq-
uids are exposed to ultrasonic energy. The rate of erosion depends on the intensity of power
applied, the corrosiveness of the liquid being treated, and the amount of use.
Periodically inspecting the tip will help you recognize erosion early. As erosion progresses, the
color of the tip changes from its original polished appearance, first to light grey and then to
dark grey. Concentric rings begin to appear, and finally the tip becomes rough and pitted,
resulting in loss of power output. As it erodes, the tip can also introduce metal particles into
the solution, causing it to darken or discolor.
Eventually, erosion may become significant, at which point the tip will require replacement.
Page 93
7-2 100-214-239 Rev. A
Maintenance
Power Output Loss
There are several conditions that can cause a decrease in or loss of power output, including
• operating with a faul ty power supply or poor electrical connection
• operating with a loos e horn-c onv erter connect ion, and
• operating w ith a cracked or corroded horn/tip assembly.
If your unit indicates a decrease in power output, first check the Converter Cable connections,
then take the following steps to ensure that the horn/tip assembly is not loose or cracked or
corroded.
Fretting corrosion refers to a black, crusty build-up, resulting from friction between metal parts
that appears on the mating metal surfaces. Corrosion can reduce or alter system performance.
Examine all mating surfaces (microtip to converter, disruptor to converter, tip to horn) and
wipe the surfaces clean with a clean cloth or paper towel.
The 250/450 Sonifier does not require tuning. Tuning is done in the factory and cannot be per-
formed by the operator.
7.2 Reconditioning the Stack Interface
Ultrasonic system components work most efficiently when the mating surfaces of the Con-
verter-and-Horn combination (also called a “Stack”) are flat, in solid contact, and free from
fretting corrosion. Fretting corrosion refers to a black, crusty build-up, resulting from friction
between metal parts, that appears on the Stack mating surfaces. Poor contact between mating
surfaces wastes power output, makes tuning difficult, increases noise and heat, and may cause
damage to the converter.

7.2.1 Refacing the Mating Surfaces
NOTE
i Never clean the Convert er or Horn mating surfaces with a buffing wheel.
1. Disassemble the Converter / Horn Stackand wipe the mating surfaces with a c lean
cloth or paper towel.
2. Examine all mating surfaces. Ifany m ating surface shows co rrosion or a hard, dark
deposit, rec ondition it.
3. If nec es s ary, remove the threaded stud from the part.
4. Tape a clean sheet of #400 (or finer) grit emery clot h to a clean, smooth, flat surface (suc h as a sheet of plate glass).
NOTE
i Be careful to avoid tilting the part and losing flatness of the surface. Doing so
may make t he s y stem inoperat ive, du e to improper mating surfaces.

Lapping Procedure
5. Holding the part to recondition, place the interface surface on the emery cloth.
Grasp the part at the lower end, with your thumb over the s panner-wrenc h hole,
and lap the part in a straight line across the emery cl oth.
NOTE
i Do not apply downward pressure. The weight of t he part alone provides suf-
ficient pressure.
6. Rotate the part 120 degrees (1/3) to the next hole.
7. Stroke the part an equal n umber of times at each rotation (2 or 3).
8. Pick up the part and lap it once or t wice in the same direction.
9. Rotate the part 120 degrees, placing your thumb over the spanner-wrench hole,
and lap t he part the same number of times as described above.
10. Rotate the part another 120 degrees to the next spanner-wrenc h hole, and repeat
the l apping procedure.
Re-examine the mating surface. If necessary, repeat steps 5 through 10 until you remove most
of the contaminant. This should not require more than two to three complete rotations for an
aluminum horn or booster; a titanium component may require more rotations.
7.2.2 Horn Tip Cleaning
Take the following steps to clean the horn’s tip threads:
1. If the horn has a replaceabl e tip, remove it and clean its threads in alcohol.
2. Swab out the end of the horn threads with a cotton swab and alcohol.
3. Make sure both the horn and the tip are clean and completely dry before you reassemble them.
Refer to the Tip installation procedures for information on tightening the Tips. This is found
in
Section 4.4, Assembling the Equipment,
beginning on page 4-9.
4. Use a s panner wrench on the horn and an open-end wrench on t he t ip toi ns tall the
tip u sing the following torque specifications:
1/4-20 — tighten at 90-inch-lbs/10.16 Newton-meters
3/8-24 — tighten at 180 inch-lbs/20.33 Newton-meters

7.2.3 Stud Reinsertion
The Stud is intended to be a use-only-once part, as it has knurls on its end which ‘bite’ into the
relatively softer horn material. The studs are also specially designed to withstand ultrasonic
stresses. If you must temporarily re-use a used stud, especially with an Aluminum horn, it is
very important to clean the threads and the horn of the previous shavings.
1. Using a file card or wire brush, clean any chips from the knurled end of the stud.
2. Using a clean c loth or towel, clean the threaded hole.
3. Examine the knurled end of the s tud. If worn, replace the stud. Examine the stud
and threaded hole for st ripped threads . Do not use a damaged ultrasonic horn or
converter.
NOTE
i Threaded studs cannot be re-used in titanium horns.
4. Clean t he s tud and the threaded hole before reinserting it.
5. Apply one drop of Loc t ite to the stud and insert it into the horn.
6. Retighten the stud. Use the following torque specifications:
After the Stud has been reinserted, you can reassemble the Horn to the Converter. Follow the
same procedure as found in the Installation section of this manual. See
Section 4.4, Assembling
the Equipment,
beginning on page 4-9.
