Alarm Code
Alarm Message
Explanation
Solution
U100
Configuration Fault
Default Setup corrupted, Model Number in-
correct, Serial Number incorrect, Feedback
Scaling incorrect, etc.
This is a disabling condition for the generator; contact
Dukane.
U101
Bad Parameter Alarm
Internal generator fault.
Contact Dukane.
U102
Watchdog reset Alarm
Internal generator fault.
Contact Dukane.
U103
Hardware Fault
Hardware configuration or options were
changed since last generator power up.
This is a disabling condition for the generator; contact
Dukane.
U104
Frequency Overload Fault
1 (PLL Lock Fail)
The generator did not obtain a frequency
lock by the end of ramp up period.
Press Test button on the power supply. Verify that the
ultrasonic stack will operate in a test condition.
Verify that the stack is operating at proper Frequency
and Power draw.
reduce trigger pressure, force, and/or down speed.
If stack will not operate in test perform stack care and
maintenance.
Follow this link to stack care and maintenance proce
-
dure.
If Stack will not operate in test condition, remove horn
and re-inspect.
Enable “Advanced Process Settings” to adjust free run
frequency to the “in air” operating frequency that results
from a test.
Enabling a pre-trigger source that allows for full ramp-
up time to elapse still “in air” before contacting the
part should eliminate all “Frequency Overload Fault 1”
occurrences for a properly maintained stack.
If the above steps do not resolve problem, contact
Dukane.
U106
POS Peak Overload Fault Generator ultrasound overload.
Check if one of the stack components is defective.
Check if one of the stack components is loose.
Check if the IQ generator's system frequency settings
are set correctly.
U107
NEG Peak Overload Fault Generator ultrasound overload.
Check if one of the stack components is defective.
Check if one of the stack components is loose.
Check if the IQ generator's system frequency settings
are set correctly.
U108
Average Overload Fault
Generator ultrasound overload.
Reduce the force being applied to the part (on a
pneumatic press) or reduce the weld speed (on a servo
press).
U109
Bad Current Loop Fault
4-20 mA current loop is not connected to
the remote amplitude card, or 4-20 mA
current loop is defective (poor electrical).
Check for proper connection to remote amplitude card.
Check for damage to wiring.
This is a disabling condition for the generator; contact
Dukane.
