5.2 Physical Description
Refer to Chapter 4: Installation and Setup 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 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. 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.

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.
