NOTE
Ramp Down Time
Ramp Down Time extends the service life
of complex acoustic stacks by minimizing
stresses encountered during the process
of shutting off the ultrasound. It is espe-
cially recommended for very large horns,
or when the ultrasound is shut off in air.

The scan takes place with Amplitude, Power and
Frequency values are shown. Figure 5-56 illus-
trates the screen view after a successful scan.
• Ramp Up Time
Although the Ramp Up time is factory set, it is vari-
able and can be adjusted to account for starting charac-
teristics of a particular stack.
The Ramp Up setting depends on the generator load at
the start of a cycle.
The Ramp Up time increases the amplitude
linearly ,
in the programmed time period at the start of the weld,
from zero to the programmed amplitude level. The
stack is brought up to the operating amplitude smooth-
ly, without shock stress.
• Ramp Down Time
Although the Ramp Down time is factory set, it is vari-
able and can be adjusted to account for characteristics
of a particular stack.
Ramp Down Time decreases the amplitude linearly to
zero in the programmed time period following the end
of the weld, when ultrasound is shutting off.
The stack is brought down from its weld amplitude,
reducing shock stress.
• Restore Advance Process Default
s
Activate this feature, and it will restore all of the ad-
vanced process settings to their factory defaults.
Buzzer
Use the Buzzer function to turn the internal generator
buzzer on or off.
Disabled - The buzzer will not sound.
Enabled - The buzzer can signal two different
events. When the buzzer in enabled, it beeps once
when a suspect part occurs, and it beeps twice
when a bad part occurs.
The default buzzer setting is Disabled.
See Figure 5-57.
• Buzzer Top of Stroke - When enabled, buzzer
sounds when top of stroke is reached.
• Buzzer at Trigger - When enabled, buzzer sounds
when the trigger point is reached.
