Dukane Manual Part No. 403-583-00
Process Controller
Settings
This section of the manual helps the reader become
familiar with the operating modes, and illustrates some
typical programming steps.
There are three welding modes available. These
correspond to the three ways in which the welder can be
used: Automation, Time, and Energy.
Select the Welding Mode
Automation - In AUTOMATION mode the PLC
controls the weld cycle. The cycle starts, and the ultrasonic
signal (U/S) activates when Ultrasound Activate/Cycle
Start Input (Pin 12) is activated. When the Ultrasound
Activate/Cycle Start Input (Pin 12) is deactivated, the
ultrasonic signal stops and the cycle is complete unless
there is a hold time programmed.
Time - In TIME mode the operator sets a maximum
time (seconds) that the ultrasonic signal will be active for
each weld cycle. The cycle starts when the Ultrasound
Activate/Cycle Start Input (Pin 12) is activated. The U/S
stops when the programmed time is reached.
Energy - In ENERGY mode the operator sets a
maximum energy (Joules) the generator will reach
during the weld cycle. [A maximum weld time must be
set when welding by energy. If the energy level is not
reached, the preset for time will determine when the
U/S is deactivated.] When the preset energy level is
reached, the U/S will be deactivated. The cycle starts
when the Ultrasound Activate/Cycle Start Input (Pin 12)
is activated. When the programmed energy is reached,
ultrasound stops.
