E-Stop Reset; Electrical Cabinet - Dukane VWA-4300 User Manual

Linear Vibration Welder 4000 Series, Model VWA User's Manual
DOOR OPEN. I've checked all the doors and cleared
the s and it still won't clear, and I can't run a
E-STOP
cycle. What is the problem?
A: If your machine is equipped with a
SET button, you have to push the
button to reset the safety circuit. If this does not clear
the problem, it is possible that one of the
door interlock switches needs replacement.
5. Q: There's a red box that says SENSOR 1 (or
SENSOR 2) on my screen and it won't go away,
and I can't run a cycle. What do I do now?
A: If you are using part-in-place detection, the part-
in-place sensor is not detecting a part loaded into the
tooling. If there are no part-in-place sensors in your
tooling, go to the UTILITIES >I/O Setup> Part
Present Put the sensors in BYPASS mode.
.
6. Q: What does it mean when I get an Autotune
Error?
A: There is either a serious problem with the ma-
chine, 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.
7. Q: There are a lot of tooling bolts. How many do I
really HAVE to install?
A: The best answer to that question is ALL of them.
There are some cases where you can use fewer. The
only legitimate reason for not using all of the bolts
is that some part of the tooling obscures some of the
holes. You must also torque the bolts to 100 foot-
pounds (136 Nt-m). If you do not, the upper tool
can become decoupled from the springs, resulting in
possible damage to the tool or machine. Similarly, a
loose lower tool will result in poor welding and can
damage the tooling or machine.
8. 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 prob-
lems. 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.
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.
why do I only have to activate one to start a cycle?
A: Machines equipped with light curtains are not
required to be equipped with two-hand anti-tie-down
cycle actuation, so as a convenience we allow the op-
erator to use either of the switches to start the cycle.
I do about it?
A: If the machine is slightly louder than 80db, it is prob-
ably running an application with a higher basic sound
level than we tested the machine for in our factory. If
you buy a Dukane machine with tooling, we always
check the total noise of the machine and tooling together.
Our standard sound insulation package is designed to
deal with the majority of vibration welding applica-
tions. Consult Dukane about the possible addition of
custom sound insulation. If the machine is significantly
louder than 80db, you probably have not installed the
fork tube covers that came with the machine (Figure
3-5, Page 19). When we ship a machine, the covers
are shipped in a corrugated box in the bottom of the

electrical cabinet.
