UNPACKING AND INSPECTION
NOTE: We recommend
keeping all carton(s)
and packing material in
case it might be
necessary to move the
equipment, or to ship it
for repair.
Before unpacking the equipment, check the shipping carton for any visible
damage. If you see any, be sure to follow the procedures described below
under “Visible Loss or Damage.” Otherwise, proceed to remove the equipment
from the carton. Before storing any packing material, check it carefully for
small parts. Then perform a visual inspection of the equipment to detect any
evidence of damage which might have occurred during shipment. Check the
following:
1. all components against the enclosed packing list,
2. all module plug-in units,
3. all wire plug-in connections.
The equipment was carefully packed and thoroughly inspected before leaving
our factory. All units are tested and checked for problems prior to shipping. It
is asked that when a problem does occur that all parts and components be
inspected for damage (especially when the unit is not in working order when
received). Responsibility for safe delivery was assumed by the carrier upon
acceptance of the shipment. Claims for loss of damage sustained in transit
must therefore be made upon the carrier, as follows:
VISIBLE LOSS OR DAMAGE
Any external evidence of loss or damage must be noted on the freight bill or
express receipt, and signed by the carrier’s agent. Failure to adequately
describe such external evidence of loss or damage may result in the carrier’s
refusal to honor a damage claim. The form required to file such a claim will be
supplied by the carrier.
CONCEALED LOSS OR DAMAGE
Concealed loss or damage means loss or damage which does not become
apparent until the merchandise has been unpacked. The contents might have
been damaged in transit due to rough handling even though the container
may not show external damage. When the damage is discovered upon
unpacking, make a written request for inspection by the carrier’s agent within
48 hours of the delivery date. Then file a claim with the carrier since such
damage is the carrier’s responsibility. The form required to file such a claim
will be supplied by the carrier. Do not destroy packing materials, or move
material from one location to another before the carrier makes their
inspection.
If the system or any unit is damaged, notify “Sonics.” “Sonics” will arrange for
repair or replacement of damaged equipment without waiting for the claim
against the carrier to be settled, provided a new purchase order is issued to
cover the repair or replacement costs. Should any damage, shortage or
discrepancy exist, please notify us immediately.

INTRODUCTION
The FM model power supply is an auto-tuned ultrasonic generator with a builtin Microprocessor that allows time and energy-based control. The
Microprocessor is programmed with a multi-function keypad and information
is displayed on the back-lit liquid crystal display (LCD). This power supply can
be used with a pneumatic actuator or with a stand-alone converter.
OVERVIEW OF ULTRASONIC PLASTICS
ASSEMBLY
WHAT IS ULTRASONICS?
Ultrasonics refers to vibrational waves with a frequency above the human
audible range which is usually above 18,000 cycles per second (Hz).
PRINCIPLE OF ULTRASONIC ASSEMBLY
The basic principle of ultrasonic assembly involves conversion of high
frequency electrical energy to high frequency mechanical energy in the form
of reciprocating vertical motion which, when applied to a thermoplastic,
generates frictional heat at the plastic/plastic or plastic/metal interface. In
ultrasonic welding, this frictional heat melts the plastic, allowing the two
surfaces to fuse together; in ultrasonic staking or insertion, the controlled flow
of molten plastic is used to capture or lock another material in place (staking)
or encapsulate a metal insert (insertion).
ULTRASONIC ASSEMBLY SYSTEMS
“Sonics” ultrasonic assembly systems are generally composed of the
following major elements: a power supply, converter, booster, horn, pneumatic
press and holding fixture, as detailed in the diagram on the next page. A
review of this diagram will help you understand the basic elements involved in
the assembly process and their relation to each other.

GLOSSARY OF ULTRASONIC TERMS
POWER SUPPLY/GENERATOR – The solid state power supply converts
standard 50/60 Hz electrical energy to 15,000 Hz, 20,000 Hz or 40,000 Hz
(15/20/40 kHz) electrical energy.
ACTUATOR/WELDING PRESS – The pneumatic actuator provides compressive force and mounting for the converter, booster and horn assembly.
The tabletop press consists of a base assembly, column and actuator (head).
CONVERTER – The converter changes the high frequency electrical energy
supplied by the power supply to high frequency mechanical vibrations.
BOOSTER – Successful ultrasonic welding often depends on having the right
amplitude at the horn face. Often it is not possible to design a horn which has
both the necessary shape and required gain (ratios of input amplitude to
output amplitude). In such cases, a booster is placed between the converter
and the horn to either increase or decrease the amplitude of the horn. In
addition to changing/maintaining the amplitude, the booster provides support
and alignment in the welding system.
HORN – The horn is a tuned component of the system which comes in
contact with the parts to be assembled. The horn 1) transfers the ultrasonic
vibrations produced from the converter to the parts being welded, and 2)
applies necessary force to the assembly while the material resolidifies.
HOLDING FIXTURE – The holding fixture or nest assures proper alignment
and support of the parts being assembled.

SETTING UP
The power supply is a free-standing assembly. It should be installed in a clear,
uncluttered location that is free from excessive dirt, dust, corrosive fumes, and
temperature and humidity extremes. The selected installation site should be
near the electrical power source and away from equipment that generates
abnormally high electrical transients. Observe the following additional
instructions when installing the equipment:
a. Allow at least 6 inches (152.4mm) at the rear of the power supply for cable
connections.
b. Position the power supply so that the front panel controls are visible and
readily accessible.
NOTE: If power supply is
to be run continuously, air
cooling of the converter
and horn is required. Use
clean, dry compressed air
filtered down to 5 microns
(supplied to converter
fitting – see page 12).
c. The power supply is air cooled; allow sufficient space around the assembly
to ensure adequate ventilation. If the power supply must be housed in a
confined space, forced air cooling may be necessary to keep surrounding
air within acceptable ambient temperature limits. Periodically check the
ventilation grille and clean as necessary.

ELECTRICAL CONNECTIONS
The standard cable supplied with a “Sonics” press is 10 feet. Optional
extension cables are available up to 15 feet without modification.
NOTE: Do not plug
the power supply into
an electrical outlet
until all other
connections have
been made.
When making the initial electrical connections, make sure the power is
disconnected and follow these precautions.
1. Do not strain or kink the cables. When going around corners, allow as wide
a bend as possible. Do not run the cables parallel to any power line within
a distance of less than 1 foot (305mm).

BASIC MODES OF OPERATION
The FM power supply’s built-in microprocesor allows the use of either timebased or energy-based cycles in four basic modes, as follows:
1. Time-based cycle with time delay triggering or pre-triggering.
2. Time-based cycle with variable force triggering.
3. Constant energy-based cycle with time delay triggering or pre-triggering.
4. Constant energy-based cycle with variable force triggering.
TIME-BASED MODES
In a Time-Based Cycle with Time Delay Triggering, the Weld and Hold
timers are actuated following the termination of a pre-determined delay
period. This delay period is initiated when the horn contacts the part to be
welded.
In a Time-Based Cycle with Variable Force Triggering, the Weld and Hold
Timers are actuated after a pre-determined coupling force is exerted on the
components.
For both of these time-based modes of operation, upper and lower tolerance
limits in energy (Ws) can be adjusted.
ENERGY-BASED MODES
In a Constant Energy-Based Cycle with Time Delay Triggering, the weld
cycle follows the termination of a pre-determined delay period. The weld cycle
continues until a pre-selected amount of energy in Watt seconds (Ws) is
delivered to the components. The duration of the weld cycle may vary, but the
energy delivered is constant.
In a Constant Energy-Based Cycle with Variable Force Triggering, the
Weld cycle is initiated after a pre-selected Trigger Force is reached. Once
again, the duration of the weld cycle is dependent upon the pre-selected
amount of energy delivered to the components.
In the case of energy-based modes of operation, the upper and lower
tolerance limits are adjustable in time (seconds).

Pre-triggering is accomplished by setting T1 to 0.00 sec, thus continuing the
calibration pulse until T2 is actuated by the horn contacting the workpiece.
NOTE: T1 should be
selected and set at 0.00
seconds only when pretriggering is required. Pretriggering during normal
welding operations can
result in surface marking.
The Delay Timer (T1) can only be set or changed when Delay Timer
Triggering (T1) has been selected. The Delay Timer is not operational when
the Force Triggering function (FT) has been selected. Attempts to access T1
when the Force Trigger function has been selected will result in the following
display:
TIMER 1 MODE IS OFF!
The Weld Timer (T2) can only be set or changed when Time-Based operation
(ZT) has been selected. The Weld Timer is not operational when the Constant
Energy function (EN) has been selected. Attempts to access T2 when the
Constant Energy function has been selected will result in the following
display:
US-TIME MODE IS OFF!
If no timer values are to be changed, press the ENTER key twice (providing
that a time value is displayed) to return to system status READY.
SELECTING AND SETTING THE AFTERPULSE TIMER
In some applications involving staking, spot welding, or a vacuum horn, the
completed assembly may remain attached to the horn. In such instances, the
Afterpulse Timer (T4) can be used to actuate the ultrasonics briefly to release
the assembly as the press retracts to rest position.
NOTE: If the Afterpulse
Timer is not in use, (which
is the case if the Mode
Code function “U” is not
displayed), T4 should be
cleared so that the
displayed value is 0.00 sec.
Although the Afterpulse
Timer is not operational,
any value set for T4 will
extend the Hold Timer (T3)
duration by that value.
To use the Afterpulse Timer (T4), press the INFO key four times to display the
current Mode Codes, for example, T1 ZT NB IS 1 48 M. Press the numerical
key 5 and the letter “U” will appear in the fifth position of the LCD display

keys 1 and 2 to select the alternate functions FT and EN. The new mode
codes (in the first and second positions of the LSD display) will now appear
as follows:
T1 ZT NB IS U
1 48 A
The Delay Timer (T1) and Weld Timer (T2) are not active in this mode
(because triggering is initiated by the piezoelectric load cell and weld cycle
duration is determined by the pre-selected level of energy delivered to the
components being assembled). The Hold Timer (T3) is active and can be set
in the usual manner.
Force Trigger (FT) and the quality control tolerance limits (+LIM/-LIM) are also
active in this mode and can be set in the usual manner.
TIMER 5
Timer #5 is an abort cycle timer that can override the hard coded value of 9.99
seconds as an absolute time out when in the Energy mode.
Timer 5 is set in the same manner as the other timers l through 4. If the abort
cycle feature is not to be used, Timer 5 should be set to 9.99 sec. If Timer 5
were set to zero (0), then welding in the Energy mode could not occur
because the counters start simultaneously. The weld cycle will be terminated
by whichever applicable time limit is reached first. Again, timer 5 can only be
used when welding in the Energy mode. Timer 2 and Timer 5 cannot be
utilized simultaneously.
SELECTING AND SETTING THE MAXIMUM WELD TIME (in
Constant Energy Mode)
In the Constant Energy Mode, the Abort timer (T5) overrides the actual weld
cycle time and can therefore limit the maximum ultrasonic weld time permitted
for an assembly. That is, if the value set for the Abort timer (T5) is reached
before the programmed energy value is met, sonics will be terminated and the
hold cycle will be initiated.

JOB SEQUENCE
Once jobs have been stored, they can be sequenced in accordance with
application requirements. Saved jobs can be sequenced in any order and
may be repeated in the sequence up to a maximum of 9 steps. Each job in
the sequence is considered one step, with a maximum of 9 steps in a
sequence before the sequence is repeated. The weld line report to the
printer/CRT will include the step number in the sequence. The LCD screen
display will indicate the step in the sequence that will be performed in the next
weld operation.
To use the job sequence feature, press the INFO key 7 times (from the
READY 1 mode). The LCD display will show the following:
SEQUENCE OFF
To sequence, first press the CE key. The LCD display will change to:
SEQUENCE
Use the numerical keypad to enter in the numbers corresponding to the
sequence of stored jobs to be utilized. For example, a display of “SEQUENCE
1324182” will sequence Job l, then Job 3, Job 2, and so on. If the system
does not respond to (and display) an entry, it is because there is no job saved
under that number.

NOTE: Sequence repeats, going back to first cycle.
CAL PULSE
The microprocessor controlled welder calibrates itself prior to each weld
cycle. The use of the calibrator (cal) pulse enables the machine to
automatically monitor the idle losses in the converter/ booster/horn assembly
just as the head begins its descent to the part. The system adds the energy
necessary to vibrate the horn in air, to the total energy programmed to weld
a part. The cal pulse is utilized only in the Constant Energy mode, although
it is activated during all modes of operation. Occasionally, it is necessary to
turn the cal pulse off. For example, in order to place a part into the horn prior
to welding (i.e.; vacuum horns), the cal pulse can be turned on and off from
the front panel.
Press the INFO key 8 times from the READY 1 mode. The display will read
either “CAL PULSE IS ON” or CAL PULSE IS OFF.” Press the CE key, (which
will act as a toggle) and the cal pulse will be either turned on or turned off.
The system will acknowledge by showing the new (on or off) setting on the
LCD display.

KEYPAD SECURITY
The keypad can be “locked” so that all operating parameters that are selected
and set with the keypad are locked in, preventing unauthorized cancellation
or adjustment.
To activate the security feature, first press the INFO key 4 times to display the
current Mode Codes (i.e., T1 ZT NB IS 1 48 M, or other variation). Then,
press the numerical keys 0 and 7 in sequence within one second to lock the
keypad. When the keypad is secured in this manner, all parameter values
can still be displayed, but the CE key is not functional (the red LED will not
light up and parameters cannot be cancelled or changed). Any attempt to
change or enter parameters with the CE key will result in the following
message being displayed on the LCD screen:
K E Y B OA R D I S L O C K E D
To return to normal operation and unlock the keypad, repeat the lock
procedure - press the numerical keys 0 and 7 (within one second) while the
Mode Codes are displayed. The red LED in the upper corner of the CE key
will be illuminated again to prompt and permit cancellation.

PRINTER INTERFACE AND OPERATION
PRINTER OPERATION
NOTE: Use of a
printer causes the
cycle to be extended
by approximately
200 ms.
If a printer is to be used for documentation of the dynamic process conditions,
it must have an RS232 serial port interface, a buffer of 2K bytes and be
capable of accepting a transmission rate of 4800 Baud. Following completion
of an assembly cycle, the assembly number, percentage of maximum power
used, energy level, weld cycle duration and reject status can be printed.
When the number of welds or number of rejects is displayed on the LCD, as
a result of pressing the INFO key the requisite number of times, that same
information can be printed.
The green LED in the upper corner of the PRT key must be illuminated for a
printout of process conditions to occur. Press the PRT key to obtain a printout.
Refer to the printer displays shown on the next pages for examples.
PRINTOUT OF THE WELD ENERGY CURVE
A graphic display of the actual weld curve can also be printed out if a printer
with a serial port interface and a buffer of 2K bytes, such as an Epson Model
LX-810 or comparable, unit is used.
The printout of the weld curve plots the actual pattern of instantaneous
loading as a function of time. The vertical line at the beginning of the printout
indicates the idle losses of the converter, booster and horn in air; and the area
under the curve corresponds to the energy delivered throughout the cycle.
(Refer to the sample printer displays on the next page for examples.)
The printout of the weld curve is initiated by pressing the ENTER key for
approximately 1 second until an audible alarm sounds and the following
message appears on the LCD screen:
* DATA TO P R I N T E R *
The printout requires approximately 70 seconds to complete, with a Baud rate
of 4800.

REJECT PRINTOUTS
The reason for a reject, such as ± LIM or T5, will be printed out for each weld.
If the Timer 5 limit is exceeded, then the printout will read as follows:
25 76/o 176.6 ws 0.40 sec. **** Reject T5
For the example above, the printout indicates that this cycle was rejected
because the Timer 5 setting (0.40 sec.) was exceeded. In this case, the red
LED’s in the corners of both the +LIM and -Lim keys will be illuminated.

COUPLING FORCE MEASUREMENT (Model 1098 only)
To measure the actual horn coupling force, turn the head down key switch
clockwise. Then, as the head is descending, press the F TRIGGER key and
keep it depressed until the horn contacts the parts.
The F TRIGGER key must
be depressed before the
horn makes contact or an
invalid force measurement,
or the value “0%,” will be
displayed.
The coupling force will be displayed on the LCD screen as a percentage of
the maximum available force. (100% = 50 Psig = 245 Ibs. =1,090 Newtons)
Release the head advance control(s) to terminate measurement.
Because of the characteristics of the piezoelectric load cell, the display will be
accurate only if the temperature remains constant and the period of
measurement does not exceed 30 seconds. If a 30 second duration is
exceeded, release the head advance control and repeat the procedure above.
CLEAR PARAMETERS
To cancel all variable parameters and release keypad security, press the
INFO and F TRIGGER keys simultaneously when “SONICS & MATERIALS”
appears on the LCD screen at start-up. The power supply will return to normal
Force Trigger Operation with Delay Triggering mode.
All keypad LED’s will light up and stay illuminated until the INFO and F
TRIGGER keys are released and the unit is turned Off.

OVERLOAD PROTECTION
The overload protection circuit will terminate sonics when the system is
operated under adverse conditions, i.e., improper tuning, excessive power
supply loading, loose or failed horn or booster, thereby protecting the power
supply and other system components. When an overload condition exists, the
RESET button will illuminate and remain lit until the button is pressed
(regardless of whether the condition is corrected or not). If a repeated
overload condition exists, resolve the problem before a failure of the power
supply occurs.
If an overload condition exists, try the following:
— decrease horn force
NOTE: System will still
cycle even though the
power supply is in
overload condition, but
sonics will not be
delivered.
— decrease amplitude (change booster or decrease output control)
— decrease downspeed
— check for loose or broken studs
— check the coupling surfaces between horn/booster and booster/converter
— check for cracked horn or booster
— check to see if the load meter exceeds 100% during weld process (if so, a
higher powered unit is needed)
If you cannot remedy the situation, contact Sonics’ Service Department at
1-800-745-1105.
