Pin 17 (Programmable Status Output 3)
Pin 17 is a digital active low status output that activates
when the system is regulating the amplitude level cor-
rectly. This output becomes an open circuit when the
system falls out of regulation. When that happens, it can-
not adjust the system output to the output level that was
programmed as the regulation set point.
This signal will be activated at the end of the ramp-up
time until the beginning of the ramp-down time. This
status signal will be active for the time the ultrasound is
at the programmed amplitude setting.
The output can be assigned to
Amplitude Regulation
Status , Servo Error Status, Home Servo Status or
Teaching Status .
[Pin 17 default output: Amplitude Regulation Status .]
Pin 18 (Not Used)
Pin 19 (System Power OK Status Output)
Pin 19 is a digital active low status output that activates
when no fault conditions are detected by any of the power
fault detection 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 active low status output that activates,
either momentarily or until the start of the next welding
cycle, when the welding parameters recorded during the
previous 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 active low status output that activates,
either momentarily 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 system
is ready to activate ultrasound or begin a weld cycle. Pin
22 is a digital active low 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 active low status output that activates,
either momentarily 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.
