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
specications 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 specications, 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 xture or part).
e. Verify that the REAR panel AC switch is ON.
The front panel AC button should be RED.
2. Push the generator front panel power button to ON.
The power button will start to ash RED on and
off for LESS THAN 20 seconds. It will then turn
GREEN. This indicates that the system is operating.
If the power button display stops ashing but re-
mains RED, do not go any further, there is a problem
with the input circuit.
3. Using iQ Explorer, go to the Utilities tab. Press the
TEST button. See Figure 5-1.
a. System Power Output:
• If the power output display remains less
than 20% of the power supply's rated out-
put (See Table 10-III, Page 113.) and the
horn frequency (ie: 220 Press) is within
19,500 Hz and 20,500 Hz, the stack is
operational.
(340 Press) within: 29,500-30,500 Hz, &
39,500-40,500 Hz.
• If the power output exceeds the 20% indica-
tion, there may be a problem with the stack.
