5.2 Physical Description
Refer to Chapter 4 for dimensional information.
5.2.1 Standard Items
Actuator Support
The actuator support is firmly clamped to the column. With the actuator support, you can adjust the height
of actuator housing above the fixture position. You can set the height as needed for your application, or to
facilitate servicing.
Actuator Base
Slide Mechanism
The slide mechanism is based on eight sets of preloaded, permanently lubricated bearings, providing con-
sistent, precise alignment of the horn, smooth linear motion, and long-term reliability.
Limit Switch
The optical Upper Limit Switch (ULS) signals the control circuits in the power supply that the carriage has
returned to the top of its stroke (home) and is ready to start another operating cycle.
The power supply uses the ULS signal to perform various control functions, as in the following example:
• Electronic Pretriggering: A 2000-series Power Supply can use the ULS signal to activate ultrasonics
before the horn contacts the workpiece. Pretriggering is used with large or difficult-to-start horns and in
specialized applications.
Mechanical Stop
The mechanical stop limits the downward travel of the horn. To prevent equipment damage, adjust the stop
so that the horn will not contact the fixture when no workpiece is in place. There is an indicator on the right
side showing the position of the stop block. It is not intended for use in welding by distance.
