The iQ Generator Won’t
Cycle
Just before a weld cycle starts, the iQ generator waits for an initiating signal.
If an initiating signal is applied and the system does not begin to cycle,
check the following:
• Make sure the iQ generator’s Initiate Mode in the Process Control
menu is set to the appropriate setting:
Manual if using activation switches; Auto if the system is congured
for use with an automated system.
NOTE
The Initiate Mode selection must be set for each setup
used. This is extremely important in the case of Sequenc-
ing and setup selection.
• Remove all inhibiting inputs and check that no Cycle Start error mes-
sages are displayed.
• Ensure that cabling is connected properly and that user interface cir-
cuitry is operating.
No Ultrasound
• To verify that the generator is producing an ultrasonic signal, use the
acoustic stack test procedure described in Section 5, System Opera-
tional Testing.
• Verify at the Utilities page, that the OFFLINE box is empty (not
checked.)
• Verify pressure settings.
• Review the program. There should be a Weld Time P1 (and Weld Time
P2 if dual pressure is used). Set the weld characteristic to Display in
the iQ Explorer's Process Limits tab.
• Select Cycle Data, start the cycle, and view the reported Weld Time
shown on the display. This tells that the controller has directed the
generator to produce the ultrasonic signal for the programmed time.
• Verify that a time for the weld cycle is displayed.
• Verify that a value shows in Weld Peak Power, Method 1.
NOTE
If no value displays, there is a
problem. For help, go to Contact-
ing Dukane, Page 105.
