Pin 18 (Analog Amplitude Output (0-10 VDC))
Pin 18 is an analog output signal used to monitor the
system amplitude setting. The scaling on this output sig-
nal is 100% amplitude = 10.0 VDC, or 0.1 VDC per 1%
amplitude. Using this monitor output, the control system
can verify that the amplitude is set to the expected pro-
grammed amplitude level.
Pin 19 (Ultrasound Status Output)
Pin 19 is a programmable output that defaults to a digital
output that activates when the system is delivering ultra-
sonic power to the load attached to the ultrasound output
connector. This output will be an open circuit when the
ultrasound output is off.
Pin 20 (Any Fault Status Output)
Pin 20 is a programmable output that defaults to a digital
output that activates whenever any fault condition is
detected that terminates/inhibits ultrasound output and
normal system operation. This output will be an open
circuit when no system fault conditions are detected. Any
Fault output remains active until cleared by the System
Latch Reset input or by the start of the next weld cycle.
Generator faults that will activate the Any Fault output:
• Overload (Average, Peak, Frequency, Over Voltage)
• Over Temperature Fault
• System Power Fault
Pin 21 (Overload Status Output)
Pin 21 is a programmable output that defaults to a digi-
tal output that activates whenever any overload condition
is tripped. Activation of the overload status output sig-
nal could be caused by an Average, Peak Frequency, or
Over Voltage overload condition. After the overload status
output activates, it will remain active until cleared by the
System Latch Reset input or by the start of the next weld
cycle. This output will be an open circuit when no over-
load conditions have been detected.
Pin 13 (Isolated Ultrasound Common)
Pin 13 is the common connection for Pin 12 (Ultrasound
Activation/Cycle Start Input). Pin 13 is electrically iso-
lated from chassis ground. Using isolated sourcing (PNP)
output drivers, this common line would be connected to
isolated ground potential. Using isolated sinking (NPN)
output drivers, this common line would be connected to
the isolated positive supply voltage output. For correct op-
eration of the Ultrasound Activation/Cycle Start input it is
critical that this pin is connected to either isolated ground
or positive supply.
Pin 14 (Analog Input (0-10 VDC))
Pin 14 is an analog input used when connecting a distance
encoder. An encoder is used when using the weld methods
DISTANCE or POSITION. When using either of these
weld methods, it is also recommended using Dukane’s
Trigger by Power feature. Dukane recommends using the
MPS series analog encoder made by SICK or equivalent.
See Figure 3-3 for wiring information.
Pin 15 (Analog Input (0-10 VDC))
Pin 15 is an analog input used to remotely control the
generator amplitude setting. The input voltage range
defaults to 2-10 VDC with 2 volts representing a 20%
amplitude setting and 10 VDC representing a 100%
setting. This input is active when the Analog Inputs “J5
Pin 15” is enabled and the “Weld Amplitude Remote” is
enabled under the Amplitude menu screen.
Pin 16 (Analog Ground)
Pin 16 is the signal common (ground) connection for all of
the analog signals (on Pins 14, 15, 17, and 18). This signal
common pin is connected to system chassis ground and is
not isolated from the generator chassis. This is an analog
signal ground connection. Do not connect anything to this
ground connection, except the wiring to the inputs/outputs
of the analog devices.
Pin 17 (Analog Power Output (0-10 VDC))
Pin 17 is an analog output signal used to monitor the power
output from the welding system. The scaling on this output
signal is as shown below:
1 Watt = 0.001 VDC (1mV per Watt)
Example
: • 20kHz system measures 0.525 VDC on
Power Monitor Output = 525 Watts
