Hello everyone, I am Professor REYNER, I am again on our YouTube platform,
let's learn together to continue with the tutorial videos on the use and management of the simulation
software that we say on this occasion, we are going to do exercise number 8 and well, we are not going
to We are going to continue with all of you here and I hope I look forward to all those who
wish to ask so they join the platform and share the content to reach more people
on their social networks and today we are going to make the video of this This time we are going
to read the problem statement which says the following situation elaborated an electrical
diagram of three lamps with the following working conditions when pressing on
two seconds after it is turned on we are going to change the time here we are going to put three seconds
remember that The examples are the times that I am stimulating perhaps for practices are
well let's say this only for stimulation but the reality d because the times
could be different and then the ignition sequence will be repeated in this is what it
raises in the second working condition where it says that the lamp will automatically turn
off after ten seconds and then the ignition sequence will be repeated again
and off because you have to add these here I had not added them so that means that
they will be turning on and off turning on after three seconds ten seconds turned on
turns off and this sequence of on and off repeats then here we have it they
say that They are wrong for emergency in the previous video we explained the importance of what
the emergency stop was, this for emergency takes away the energy in the entire system in the case
of the switch the stop button is a push button and well he only turns off the system
but ceasing to press for the mechanism in how it is physically manufactured since it returns
to its initial position in the case of the push-button and by Therefore, there is electric current
to the whole system, even if it is not turned on, but there is electric current and the presence of
electric current, so we are going to see this exercise number 8 well, we are going to put number 8
here, we are going to configure this situation well and we have here on the stop is the day
the lamps are paid and on off timed lamps we are now going to make a continuous cycle a continuous
sequence of on and off so in the previous exercise we were looking at
our command that we already explained why we have this order of in the case of command in the case of
control the coil turns on the timer 1 the timer boe turns on this sequence we already explained well
in the previous video now what we are going to do practically is this good we are going to add one
more coil in such a way that when it is turn off the lamps not the shutdown does not come here
until the power on to this control but we are going to add here a line of work with a
coil that does not turn off momentarily for three seconds and the sequence repeats
then we are going to see us come here are the coils we are going to locate our our relay
relay coil call it as you consider and this one because we are going to put the mark the
name below we already have each one because then we are going to locate each two this coil
is going to turn on when we activate the relay that is going to take care of that because it will be the
cable then we are going to locate here this is going to be the relay that is going to be in charge of the ignition
of the status ok then now the coil k 2 is the one that is going to be in charge of sending the
timers to turn on and well here it would be green so now we are going to start the interconnections I
still need it but let's go to go slowly then we leave this interconnected here we are going to connect
the new coil that we have, well, most of the connections were already there but most of them were also
explained in the previous video so I was not doing it so much in this, in this second video
of turning the lamps on and off, we are going to say so automatically and in this case,
the cycle will be repetitive, that is, here we have it, the lamps are going to turn on but now that There is
a small detail that we do not see, we have not prepared it in this case when the timer stops
working where are you going to send that timer to pay in the previous video we explained that we had it
on the command line and this time we are going to put in this relay that we have added
to the scheme of our work today and there we are going to put our auxiliary contact
of that of that timer which is going to be because the timer timer 2 so here it is very close to
this situation. Put here the only thing that now is going to generate the work that I have to
move all the other components that I had already created then it does not matter we are going to do it right
in the coil I did not pay attention it does not matter we take it out again and we are going to put it here again and Then
the problem this is going to be the coil here two that we had already configured and well let's see now
if we can delete the point without deleting the line, the problem could not be done and it also took me in the
deletion what it said on and off of the lamps well I am not going to erase all these
errors that I am making so that they remain there true so that they see that it is not easy to also be
here manipulating the software to the deficiencies because they can happen to anyone the
errors exist and well one has to live learning from mistakes well here it is here
we have we are going to say this way this interconnection now we are going to do this again and nothing I think
that now it is going to look good like this one I like it to be left out of line and
out of range here we have the lamps we are going to interconnect them right now these three
lamps that we have been using in this exercise and this timer we are going to associate with
this auxiliary contact this auxiliary contact it will belong to timer 2 the times here we had
3 seconds here we had 10 seconds everything is fine so now we are going to see what is going to work
how it is going to work this we descend is retained each one is retained and activates the second coil
the second coil commands to extend the timer one counts the timer one of the three
seconds finish counting the three seconds the timer commands the second timer
to be turned on and the lamp is to be turned on the second timer is responsible for measuring the time they will
be on the lamp and then he will send with this auxiliary contact to turn off here
but since I was energized, check the control it will be energized so when the timer returns
to its initial position it will close and the system will recharge energy
and the cycle is going to restart again, well now we are going to do the simulation prior to
this, I had already done a simulation that he had not given me, it did not work for me simply and simply because
this contact or this contact had it, it had an auxiliary contact but from a timer to disconnection,
so you have to be very careful and look carefully so as not to make a mistake, so now
fix that now let's do the simulation and well let's see how the situation is There,
as we can see, there, it lights up later when the count ends, it sends the second
timer to activate and followed by the lamps when the new seconds end, it will send to cut here
and that is that power cut, let's say it that is the way it is for now, because how it was here the
control source the entire control line is activated it is re-energized the
lamps are turned on again after time they are paid again from here with this auxiliary contact but as it
is energized here the whole system is turned and in that way it is flowing current is understood by
turning off the system as we can observe well as I always recommend everything there is in
safety at work and right now in the diagram when it is We are working because we have to be very
careful with the elements in this software, the elements come separately and well the
auxiliary contact that works for a connection is not the same that works for the disconnection timer
if we make a mistake in one of those five that Even the terminals will not work for us, these points
also sometimes have to be put because that is why it does not work these are some faults that
the timers give if the timers are named with a capital t and the auxiliary we have it with the term
hoola it will not work There are some little houses that one is learning to say the faults
that can be given to us then how we can observe the turning on and off of the lamp it
will be intermittent it will be turning on and off the cycle is continuous until the
operator arrives by saying so The machine stoppage or it is not true, we are going to say so that there is an
accident emergency or an emergency of something that happens in the work plant and requires
this va We are going to say this way, cut the current and the operator must press the emergency stop, they already
know that the emergency torque is deactivated as it is anchored and that of the entire system is
really going to be bled out, it will be without current because we have the torque emergency
activated well without anything else to say because here we have shared another video of configuration
and management of what is said I thank everyone who has joined this YouTube
platform and this well as a motto tells us that we are going to learn together anything from my comment
that I keep learning that I continue to always follow true with the initiative of helping to learn
and teach the little that one knows because I know that on the internet in advanced countries there
are also true people who know a lot about In fact, I have also learned from those people and well,
I do not hope they share the content on their social networks, the process
reigns as always, wishing you the best you have. lucky everyone in their daily activities and
you
