Chapter 6: Operation
Initial Actuator Settings
The 2000X ao Actuator is controlled by the Power Supply. The Actuator sends operating cycle
data (such as velocity and force), status information, and alarm information to the Power Supply.
The Power Supply sends operating parameters to the Actuator, determining how and when weld
cycles are initiated and terminated. The Actuator passes distance, force, and pressure informa-
tion continuously to the Power Supply while in Setup mode. Refer to your 2000X-Series Power
Supply manual for tuning, testing, setup, and operating instructions.
WARNING
!
When using larger horns, avoid situations where fingers could be pinched
between the horn and the fixture. Contact Branson for information on an optional
guard.
6.2 Initial Actuator Settings
The Actuator is controlled by the Power Supply, however there are several functions that are part
of the Actuator. These include:
• Factory Air Source
• Regulated Air Pressure and Air Pressure Gauge (located on the rp)
• Downspeed Control (located on the rp)
• Mechanical Stop
• Actuator Position and Height above fixture (Horn travel)
• Emergency Stop (on Base, and provided as a User I/O signal for automation)
Each of these will affect the operation of the Actuator.
6.2.1 Regulated Air Pressure and Air Pressure Gauge
When factory air is present, it is delivered to the regulator, located on the rp box. The regulator
knob is a push-to-lock knob to prevent undesired changes in your air pressure settings.
CAUTION
!
When factory air is removed from the system, or the dump valve is activated, the
Actuator may “settle” to a lower position, since it is held up by the constant air
pressure. Be sure to keep your hands and fingers from under the Horn or other
pinch points, and use a block of wood or other soft material to block the Horn up
to prevent damage to the tooling.
