4 Operation
4.1 Overview
This section contains instructions for starting and operating the ultrasonic power supply and
covers the following:
• Using the U/S switch to activate ultrasonics.
• Setting the power level.
• Using Power modulation mode to remove dissolved gases from the tank liquid.
• Using Sweep mode to select the sweep speed and bandwidth.
• Using the Rate switch to set sweep speed.
• Using the Reset switch when tuning and when clearing a fault condition.
The order of the topics above is the most common sequence used to operate the ultrasonic power
supply.
4.2 Key Concepts
The following defines key concepts used when operating the ultrasonic power supply:
Line/load regulation – compensates for the tank liquid level and temperature changes as well as
line and load variations. This maintains power to less than 3 percent change for consistent
cleaning.
Auto frequency tracking – maintains optimum operating frequency around your application.
Dynamically adjusts to your preset conditions regardless of changes in your operating
environment.
Sweep mode – modulates the operating frequency above and below the ultrasonic power supply’s
tuned frequency by approximately 1000 Hz. This feature products a random wave-length pattern
in the tank to improve energy distribution and cleaning effectiveness.
Power modulation – Changes the ultrasonic waveform to provide high amplitude to assist in
cavitating viscous or difficult to cavitate liquids. The average power level is unchanged. Power
modulation may be used to improve degassing in difficult to degas liquids.
4.3 U/S Mode Function
The U/S control switch activates ultrasonic power to the ultrasonic tank or immersible transducers.
Notes You can operate the U/S control switch at the front panel when in operating the ultrasonic
power supply in Remote position.
Note: Before pressing the U/S control switch, make sure the ultrasonic power supply is powered up
and the connection to the ultrasonic tank or immersible transducers is secure.
