Pin 17 (Amplitude/Power Regulation Status
Output)
(Contact your sales representative about
Power Regulation availability.)
This status signal is most useful when the power regula-
tion mode is selected. This Out of Regulation status signal
would indicate that due to inadequate pressure against the
ultrasonic horn, the power regulation level setting can
not be achieved when the amplitude level is set to the
maximum level of 100%.
In the amplitude regulation mode, this signal will be
activated at the end of the ramp-up time until the begin-
ning of the ramp-down time. This status signal will be
active for the time the ultrasound is at the programmed
amplitude setting.
Pin 17 is a digital status output that activates when the sys-
tem is regulating the amplitude or power level correctly.
This output becomes an open circuit when the system falls
out of regulation. When that happens, it cannot adjust the
system output to the output level that was programmed as
the regulation set point.
Pin 18 (Not Used)
Pin 19 (System Power OK Status Output)
Pin 19 is a digital status output that activates when no fault
conditions are detected by any of the power fault detec-
tion circuits included in the system. This output will be
an open circuit when any power related fault is detected
in the system.
Pin 20 (Bad Part Status Output)
Pin 20 is a digital status output that activates, either
momentarily or until the start of the next welding cycle,
when the welding parameters recorded during the previ-
ous welding cycle are outside of the programmed bad part
limits. This output will be an open circuit when a bad part
has not been detected.

Pin 21 (Good Part Status Output)
Pin 21 is a digital status output that activates, either momen-
tarily or until the start of the next welding cycle, when the
welding parameters recorded during the previous welding
cycle do not exceed the programmed suspect or bad part
limits. This output will be an open circuit after a welding
cycle when either a suspect or bad part has been detected.
Pin 22 (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 23 (Suspect Part Status Output)
Pin 23 is a digital status output that activates, either momen-
tarily or until the start of the next welding cycle, when the
welding parameters recorded during the previous welding
cycle are outside of the programmed suspect part limits.
This output will be an open circuit after a welding cycle
when a suspect part has not been detected.
Pin 24 (Isolated Common)
Pin 24 is electrically isolated from chassis ground. This
common line should be connected to negative output at a
user-provided isolated 24VDC power supply. The isolated
NPN status output signals can drive PNP inputs.
Pin 25 (Not Used)
Pin 25 is an open connection.
