Operational Test of
the Acoustic Stack
The following test procedure is suggested before starting
the generator, to verify that the vibrational characteristics
of the stack fall within the range of the Digi-Trac. All
Dukane stack components are manufactured to tolerance
specifications within this range. A non-Dukane horn,
an improperly assembled stack, or a stack component
that is worn or damaged, can result in vibrational char-
acteristics outside these specifications, and will require
some adjustment. This test reveals the existence of any
problems and directs you to corrective action.
1. Check the following:
a. Make sure that the correct booster and horn for
the application are installed in the thruster.
b. Check the
iQ Series
system components for
proper grounding.
c. Check the ultrasound cable connections on the
generator and thruster for proper seating and
security.
d. Verify that the horn is not under load (not in
contact with a fixture or part).
2. Push the generator REAR panel AC breaker switch
to ON. Then the FRONT panel power indicator will
flash on start-up, and finally turn a steady GREEN.
This indicates that the system is operational.
If the power indicator stops flash ing, but remains
RED, do not go any further, there is a problem with
an internal power supply.
3. Using
iQ Explorer II
, go to the Utilities tab. Press
the TEST button. See Figure 7-1.
a. System Power Output:
• If the power output display remains less
than the typical 200 Watts and the horn
frequency is within the standard frequen-
cy range, the stack should be operational.
• If the power output exceeds 200 Watts,
there may be a problem with the stack.
b. If a frequency overload alarm is displayed, a
mismatch has occurred between the genera-
tor’s ultrasonic output signal and the stack.
See the
Press Alarm Messages, Appendix E
.
Also see Figure 7-3 that shows an example of an
alarm that caused cycling to stop.
