Power
To verify operation of this feature perform an acoustic stack test.
If no power is displayed, contact Dukane.
The electronic pressure regulator and pressure transducer are components of
the same system. The electronic pressure regulator accepts commands from
the iQ generator and sets the air pressure to the desired user-selected value.
The pressure transducer senses the pressure and transmits it to the iQ genera-
tor via a 4-20mA current loop. To check the pressure components:
1) On the Process Settings page, verify that a Weld Pressure 1 setting
has been made.
2) Go to the Process Limits page, and make sure the parameter, Contact
Pressure has been set to be displayed
3) Cycle the machine. Then, go to the Cycle Data screen and see that the
pressure reading is shown for the cycle just completed.
Force Transducer (Load Cell)
The force transducer senses force exerted on the part and controls when the
ultrasound signal is applied. Check the force transducer by looking at the
FORCE measurement on the View Parameters menu. The measurement
should change when upward pressure is applied to the acoustic stack.
1) On the Process Settings page, select FORCE as the Trigger Type,
and make sure Trigger Method is Normal.
2) Enter a FORCE value, perhaps 10 lbs for purposes of this check.
3) Go to the GRAPH page. Select an axis, and dene it as FORCE.
4) Go to the GRAPH DISPLAY page.
5) Cycle the machine, then look at the graph to verify that the FORCE
was at or near 10 lbs (the programmed FORCE setting).
Electronic Pressure Regulator and the Pressure Transducer
Avoid injury when touching the acoustic
stack! Wear proper hand protection, and
grasp the acoustic stack in areas that are
smooth or dull. Then, carefully apply upward
pressure until a change in the Force mea-
surement is seen on the iQ Explorer display.
