Power Supply Configuration
5.4.1
Selecting the Alarm Mode
The DCX S Power Supply activates ultrasonic power after receiving an External Start
signal. Ultrasonic power remains on until you turn off the power supply or the External
Start signal. The DCX S Power Supply response to alarm conditions can be configured to
operate in one of two modes:
• Latching: In this mode the DCX S Power Supply requires alarm conditions to be reset before a
new weld cycle can begin. To reset alarm conditions while in this mode, either press the front
panel Reset key or send an External Reset signal using the user I/O connector
• Non-Latching: In this mode the DCX S Power Supply does not require alarm conditions to be
reset, and new weld cycle can begin upon receiving an External Start signal
The alarm mode is factory-set to non-latching. For instruction on how to change the alarm

and to
your DCX S Power Supply Web Page Interface Instruction Manual (100-412-187).
5.4.2
Configuring the Power Supply
Certain power supply configurations can be modified from the factory setting if needed.
Although not usually requiring modifications from the factory setting, the following
features are selectable:
• Amplitude Control: Allows for varying the amplitude (10% to 100%) using the front panel LCD,
the web page interface, or by way of external controls (analog signal applied though the user I/O
analog input)
• Latching Alarms: Provides an option for selecting the power supply alarms to be latching (reset
required) or non-latching (reset by reapplying the start signal
• Start Ramp Time: Provides a selection for different start ramp times. This controls how fast the
amplitude of the horn rises from zero to the currently set amplitude. Long ramp times may be
useful when using large horns or high gain stacks
• End of Weld Frequency Store: Provides an option for selecting if the stack frequency is stored
at the end of each weld cycle
• Seek Ramp Time: Provides a selection for different power supply seek ramp times
• Timed Seek: Provides an option for monitoring, and storing the operating frequency at timed
intervals (60 seconds). Periodic frequency seeks may be helpful when welder is not used for long
periods of time. Seeks are timed from the moment sonics was last activated
• Seek Time: Provides an option for selecting seek duration
• Frequency Offset: Allows for varying the start frequency by way of external controls (analog
signal applied though the user I/O analog input) or setting a fixed value using the web page
interface. This is useful for certain applications, where the force imparted on the fixture or anvil
causes a frequency shift in the stack’s operation
For instruction on how to change the power supply settings refer to
and to your DCX S Power Supply Web
Page Interface Instruction Manual (100-412-187).
NOTICE
Consult with Branson before changing any default factory setting.
