9. Q: When I push the test button on the Autotune screen
(Figure 6 - 2 7, Page 68), what am I supposed to hear?
A: You should hear a loud, clear, single-note tone
similar to that of a boat horn. If you hear any raspy or
buzzing sounds, or if you hear anything like a wow or
wow-wow-wow-wow sound, check the security of ALL
bolts and other fasteners in the upper tool, including
the ones securing it to the springs. If the strange sound
persists, call Dukane and ask us to listen to it over the
telephone.
10. Q: What happens if I accidentally run a cycle with the
stanchion pins extended?
A: Hopefully nothing. The stanchion assemblies might
survive a couple of cycles with the pins extended, but
they are not necessarily designed to resist damage in
this condition. You could damage the tooling or the
machine if you do this. Get into the habit of retracting
the stanchion pins immediately upon setting down
the wrench after tightening the tooling bolts. Also,
habitually looking specifically for retracted stanchion
pins prior to initiating the Autotune sequence and prior
to initiating the first cycle with a freshly installed tool
will give you two more chances to discover extended
stanchion pins before you risk damage by cycling the
machine with the pins extended.
11. Q: It is a problem that the coils are getting hot?
A: Yes. The bottom surface of the coils should not be too
hot to touch. It probably indicates that the machine has
not been Autotuned, the upper tool is outside of the
weight range for the machine, or there is something
loose in the upper tool. If you have checked all of these
issues and the problem persists, contact Dukane.
12. Q: What do you mean by acoustically coupled?
A: Acoustic coupling is a term we use to describe the
tendency of a multipart mass to vibrate as though it were
one piece. If the upper vibration tool has some loose
bolts in it, the individual pieces can vibrate relative
to each other, which causes significant problems. The
tooling is then said to be decoupled from the springs.
Both the machine and tooling can be damaged if this
condition exists for a prolonged period.

13. Q: When I try to Autotune the machine nothing
happens and then after a period of time I get an
Autotune error. What is the problem?
A: Press the HOME MACHINE button on the touch
screen display and follow instructions on the message
banner. Refer to Figure 8-1, Page 113.
14. Q: What does it mean when I get an Autotune Error?
A: There is either a serious problem with the machine,
or there is some decoupling occurring between the
machine and tool or within the upper tool or, more
likely, the upper tool is outside of the weight range of
the machine.
15. Q: Why do I have to Autotune the tooling?
A: 1. During an Autotune the machine seeks the
optimal operating frequency for that particular upper
tool/spring assembly. If an Autotune procedure is
not done, the machine will be fighting the natural
resonance of the tooling/frame assembly, which may
result in poor and/or inconsistent weld quality.
A: 2. Fighting the natural resonance of the tooling/
frame assembly results in wasted energy. Since you
cannot create or destroy energy, only change its form,
this wasted energy shows up as heat, especially in the
coils. Overheated coils will fail prematurely, resulting
in unnecessary downtime and expense.
16. Q: What should I do with the eight grease zerks on
the machine?
A: We recommend you grease these locations once
or twice a year (in severe environments it may be
necessary to do it more often) with a good general-
purpose industrial grease.
17. Q: Why do I have to reset the machine every cycle,
or quite often?
A: The most common cause of this is the operator
breaking the light curtain just prior to the sliding door
becoming completely open. Make sure the door has
lowered completely before breaking the light curtain.
18. Q: I've installed a tool, done the Autotune, the touch
screen indicates everything is OK, but when I push the
operate switch to start a cycle, the machine just sits
there. What is the problem?
A: You have probably not connected the machine
to an air line. The only part of the machine itself that
needs pressurized air is the sliding door.
