Emergency Stop - Nussbaum WAB 02 CCT Instrucciones De Uso

After having pressed the button, the core process begins. The
robots start traveling to the rear. They are searching for a wheel,
using an infrared detector. But, any object of more than 10cm
width would be interpreted as a wheel. Even though there are
safety mechanism in place, you should anyway make sure that
there is nothing put onto the lift.
If one of the robots will identify a toolbox that was forgotten on the
lift runway, it will first stop there. But, as soon as the second robot
passes that area without finding something on its side, the first
robot will go on to find the real wheel.
If none of the robots is moving, you should check first whether the
emergency stop button is depressed. If so, pull it out.
Also, you can check whether there is a hidden error message box,
by pressing ALT-TAB on the keyboard. You should only find two
programs: The alignement software and the SMI utility program.
If the robots are moving, but there is an obstacle in the way, and
if it is only a person standing in the way, the amperage limiter will
build up a certain, limited pressure. Should this pressure not be
sufficient to go on moving, there will be an error message after a
short while. But, if the obstacle is removed within a short time, the
process will directly continue.
With the emergency stop button, you can stop all
movement of the robots and the hydraulic system. We
recommend to use it only when really needed, as you
will have to repeat the entire process, and this costs
time.
Searching for the wheels, the infrared detector gets a signal as
soon as whatever object is found within the detection range,
which acts as a reflector. The center of the wheel is found, by
checking where the reflection begins and where it ends. After-
wards, the robot is positioned to the point exactly in the middle
between beginning and end of that object. Watching that
procdure, it will look as if the robot missed the wheel. But as soon
as the robot turns back at the end of the wheel, the situation gets
evident.

The first stop on the front axle is only for reference, measuring the
car's symmetry axis. On that stop, only the wheel centers are
being measured. As soon as the robot is placed correctly in front
of the wheel, the projector starts to beam a series of black and
white stripes onto the wheel (left). This ‚Graycode' is preparing
measurement. Continuous measurement takes place if the prepa-
ration succeeded. You will see coloured stripes continuously
displaye onto the wheel (right).
If there is a problem during measurement (e.g. too much ambient
light, no communication to the probes, wheel not visible for the
camera because of an obstacle, measurement frequqncey too
low etc.), you will see a message box that will tell you exactly, on
which side the problem came up. In many cases, the problem
cures itself within some seconds.
First of all, you will be able to tell whether the probe PCs are
switched on, and whether the projectors on both sides are ok.
In that case, the warning message will disappear, and the measu-
rement process is going on. If that does not work, you can choose
from the dialog options on that message box. One option is to
restart the gray code on the probe, simply by pressing ‚yes' on the
left bottom of the message box. This makes sense in case the
measurement process has not started in a probe, or it got stuck
