b. If an overload fault is displayed, a mis-
match has occurred between the genera-
tor’s ultrasonic output signal and the stack.
Refer to the next section, Troubleshooting, and see
the Press Error Message tables.
Also see Figure 5-3 that shows an example of an
error that caused cycling to stop.
4. While pressing the TEST button, lightly touch
the side of the horn to check for ultrasonic vi-
brations. If any vibrations are felt, the stack is
operational. If there is no vibration, there may
be a problem with the stack.
If all the indicators pass their tests, the stack is within
the Digi-Trac range.
The generator is operating at the optimum setting
for this stack when the Watts displayed on the graph
(after the test) is between 10 and 20 percent of the
power supply's available output. The vibration
amplitude of the horn and booster and the mass of
the horn determine the amount of energy needed to
vibrate the stack.
• If the system passes the tests of these four steps,
proceed to the section called Procedure for Cy-
cling the System, on the next page.
• If one or more of these tests have failed, go to
the next step.
