Pin 16 (+22VDC Power Ground)
Pin 16 in the 22VDC return and is tied to the system chas-
sis ground.
Pin 17 (+22VDC Power Ground)
Pin 17 in the 22VDC return and is tied to the system chas-
sis ground.
Pin 18 (+22VDC Power Ground)
Pin 18 in the 22VDC return and is tied to the system chas-
sis ground.
Pin 19 (Ultrasound Active Status)
Pin 19 is a digital NPN/PNP status output that activates
when the system is delivering ultrasonic 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
(System Ready Status Output)
This status output signal will activate only when the sys-
tem is ready to activate ultrasound or begin a weld cycle.
Pin 22 is a digital status output that activates when a weld
processing cycle is completed and the welding process
control system is ready to start the next welding cycle. This
output will be an open circuit when the welding process
controller determines that the next welding cycle cannot
be started. This includes system faults or off line active,
but not a process fault like Overload.
Pin 21
(Any Fault Status Output)
Pin 21 is a digital NPN/PNP status output that activates
whenever any fault condition is detected that inhibits ul-
trasound output and normal system operation. This output
will be an open circuit when no system fault conditions
are detected.
In the case of an overload, this output stays
active until the start of the next cycle or until cleared us-
ing the front panel keypad or system input Pin 12 (System
Latch Reset input).
Faults that will activate the Any Fault output:
• Overload (Average, Peak, or Frequency)
• Overtemperature Fault
• System Power Fault
Pin 22
(Output Common)
Pin 22 is electrically isolated from chassis ground. This
common line should be connected to the negative output
of a user-provided isolated 24VDC power supply for a
PLC sourcing input card. For a PLC Sinking input card
this line is connected to the positive output of the isolated
24VDC power supply.
Pin 23
(Output Common)
Pin 23 is electrically isolated from chassis ground. This
common line should be connected to the negative output
of a user-provided isolated 24VDC power supply for a
PLC sourcing input card. For a PLC Sinking input card
this line is connected to the positive output of the isolated
24VDC power supply.
Pin 24
(Ultrasound Activation/Cycle Start
Common)
Pin 24 is electrically isolated from chassis ground. Using
sourcing (PNP) output drivers, this common line would
be connected to the automation system ground potential.
Using sinking (NPN) output drivers, this common line
would be connected to the automation system positive
supply voltage output.
Pin 25
(Ultrasound Activation/ Cycle Start
Input)
Pin 25 is used to start a weld cycle. Depending on the
welding process controller setup, this input signal could
be activated momentarily to start a welding cycle.
