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, pro-
viding consistent, 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 signals from the actuator to perform various control functions, as in
the following examples:
•
Indexing Control:
In automated systems, the Linear Encoder generates an Actuator Clear
signal at a preset distance along the travel of the horn. This signal can be used to trigger a
safety interlock switch, controlling movement of the material handling equipment (indexing)
before the horn is fully retracted.
•
Automatic Pretriggering:
A 2000X-series Power Supply can use the ULS signal, or
encoder distance, to activate ultrasonics before the horn contacts the workpiece. Pretrigger-
ing is used with large or difficult-to-start horns and in specialized applications.
