4.2 Physical Description
Refer to Chapter 5: Installation and Setup for dimensional information.
4.2.1 Standard Actuator 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 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: 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 2000Xc Power Supply can use the ULS signal, or encoder distance,
to activate ultrasonics before the horn contacts the workpiece. Pretriggering is used with large or
difficult-to-start horns and in specialized applications
Table 4.8 Description of Controls on Base
Name Description
Start Switches
Activate the operating cycle through the actuator to the
power supply when pressed simultaneously.
Emergency Stop Button
Interrupts the operating cycle (through the power supply)
and causes the carriage to retract. Twist to reset.
Start Cable Connects base to START connector on actuator.
