Solution
Release Switch 2 before pressing both
activation switches to start a cycle.
Verify wiring of both operating switches.
Remove active Auto-In signal.
Verify wiring to Auto-In signal.
Wait for initialization process to complete.
Cycle power on iQ generator.
If alarm persists, contact Dukane.
Change Weld Mode from Automation.
Disable Weld Method.
Adjust weld time to be greater than zero.
Adjust weld peak power to be greater than
zero.
Adjust weld energy to be greater than zero.
Adjust weld distance to be greater than zero.
Adjust weld position to be greater than zero.
Adjust maximum trigger time to be greater
than zero.
This alarm is for information only.
For servo press the distance from pre-trigger
to position of trigger is required to be less
than 0.25 inches or 6.35 millimeters.
For pneumatic press the distance from pre-
trigger to position of trigger is required to be
less than 0.75 inches or 19.05 millimeters.
Adjust Sensing Start Position to be above
contact with part. Account for variation of
heights of unassembled parts.
NOTE: Repeated occurrences of this alarm
may result in costly damage to servo actuator.
Increase maximum trigger time.
Start the weld process sooner.
