Power and Grounding Requirement

The power cord from the cabinet has a conventional three-prong plug. The
generator must be grounded through a third prong of the power cord or by use
of a conventional grounding lug adapter.
Generators are available for operation at nominal voltages of 100, 120, 200, 208,
220, 230 or 240; 50/60 Hz; single phase A.C. current.

Potentiometers

The level of output power delivered to the transducers is adjustable by a trim
potentiometer mounted on one of the generator circuit boards. This adjustment
changes the peak amplitude of the power delivered to the load, but it does not
change the duty cycle as a power intensity control would. It is particularly
useful when power reduction is necessary to protect fragile items during
cleaning.
The frequency of the power delivered to the load is also adjustable by a trim
potentiometer on one of the generator circuit boards. The factory set frequency
of 68 kHz, 40 kHz, or 25 kHz may be changed to eliminate standing waves in
the cleaning solution or to minimize resonances in the structure of the cleaning
system. These two adjustments are factory calibration procedures which should
not be performed without adequate instrumentation and technical assistance
from the factory.
