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. The tooling components are subject to wear and may require replacement 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.
