Periodic and Preventive Maintenance
The following preventive measures will help ensure long term operation of your Branson
Ultrasonics Corporation 2000X Series Actuators.
7.2.1
Periodically Clean the Equipment
Periodically disconnect the unit from power, remove the cover and vacuum out any
accumulated dust and debris. Remove material adhering to the circuit boards, cooling
intake vents and exhaust ports. Periodically disconnect the airline from the air supply,
open the air filter and clean the element and bowl with mild soap and water. External
covers may be cleaned with a damp sponge or cloth using a solution of mild soap and
water. Do not allow cleaning solution to enter the unit. Exposed steel surfaces, such as
handles, hardware and the main column may require a very light film of oil, such as WD-
40, to prevent rust in areas of high humidity.
7.2.2
Recondition the Stack (converter, booster, and horn)
Stack components function with greatest efficiency when the mating interface surfaces
are in proper condition. For 15, 20, and 30 kHz products, a Branson Ultrasonics
Corporation Mylar washer should be installed between the horn and the booster, and
booster and converter. Replace the washer if torn or perforated. We recommend that
stacks using Mylar washers be inspected every three months.
Stacks used with silicone grease, as with certain 20 kHz installations and with all 40 kHz
products, should be periodically reconditioned to eliminate fretting corrosion. We
recommend that a stack using silicone grease be inspected every two weeks for corrosion.
The inspection interval can then be adjusted longer or shorter as required, when
experience is gained for specific stacks. See the Branson Ultrasonics Corporation
instruction manuals for correct stack interface reconditioning procedures.
NOTICE
To recondition the interfaces:
1. Remove the stack from the actuator.
2. Disassemble the converter, booster, and horn stack. Observe the following rules:
In the event that you must disassemble a Stack, always use the correct spanner wrench
and a suitable soft-faced vise to remove a horn or booster, and reverse the procedures
described earlier in this Section.
CAUTION
1019571 REV. 03
The operating efficiency of the equipment will be greatly affected if
the mating interfaces of the converter, booster, and horn are not flat,
make poor contact with each other, or become corroded. A poor
contact condition wastes power and makes tuning difficult. It may
also affect the noise level and damage the converter.
NEVER attempt to remove a horn or booster by holding the converter
housing or booster clamp ring in a vise.
