7.1 General Information
If maintenance is required, contact Branson Product Support. See Section 1.6:
How to Contact Branson for contact information.
If you have a problem operating your unit:
1. Refer to Table 7.1 to locate the symptom that most clearly
describes your problem.
2. See Appendix B Parts List for available replacement parts.
3. Refer to Chapter 1: Safety and Support for equipment return infor-
mation.
7.2 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 main-
tenance to ensure optimum performance. The tooling components are subject to
wear and may require replacement after a period of time, depending on the appli-
cations. If you have a problem operating your unit, refer to Table 7.1 Symptom/
Probable Cause on page 7-7 to locate the symptom that most clearly describes
your problem.
7.2.1 Tip Erosion
Horn tips can erode. Tip erosion is a side effect of the cavitation process that
occurs when liquids 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.
7.2.2 Power Output Loss
If you observe a loss in power, several factors can be the cause. Ensure that the tip
is not corroded and is polished, as noted in the preceding paragraph.If the horn has
a replaceable tip, remove the tip and clean its threads in alcohol.
