1.2 General Precautions
Take the following precautions before servicing the Touchscreen Controller:
• Be sure the power switch is in the Off position before making any electrical connections
• To prevent the possibility of an electrical shock, always plug the Touchscreen Controller into a
grounded power source
• Power supplies produce high voltage. Before working on the Touchscreen Controller module, do
the following:
Turn off the Touchscreen Controller;
Unplug main power; and
Allow at least 5 minutes for capacitors to discharge
• High voltage is present in the Touchscreen Controller. Do not operate with the cover removed
• High line voltages exist in the ultrasonic Touchscreen Controller module. Common points are tied
to circuit reference, not chassis ground. Therefore, use only non-grounded, battery-powered
multimeters when testing these modules. Using other types of test equipment can present a
shock hazard
• Be sure power is disconnected from the Touchscreen Controller before setting a DIP switch
• Keep hands away from the horn. Force (pressure) and ultrasonic vibrations can cause injury
• Do not cycle the welding system if either the RF cable or converter is disconnected
1.2.1 Intended Use of the System
The Branson Touchscreen Controller and Actuator are components of an ultrasonic welding
system. These are designed for a wide variety of welding or processing applications.
CAUTION Loud Noise Hazard
Sound level emissions of up to 84.9 dB have been measured using a
standard test load. To prevent the possibility of hearing loss, use
appropriate hearing protection.
NOTICE
Sound level emissions of up to 84.9 dB have been measured using a
standard test load. To prevent the possibility of hearing loss, use
appropriate hearing protection.
Sound level and frequency of the noise emitted during the ultrasonic
assembly process may depend upon a. type of application, b. size,
shape and composition of the material being assembled, c. shape
and material of the holding fixture, d. welder setup parameters and
e. tool design. Some parts vibrate at an audible frequency during the
process.
Some or all of these factors may result in sound levels of up to 84.9
dB. In such cases operators may need to be provided with personal
protective equipment. See 29 CFR (Code of Federal Regulations)
1910.95 Occupational Noise Exposure. For all other countries, follow
your local regulations.
