Greetings to all of you today, Professor REYNER, I am again on our platform
to bring and share with you one more exercise in CADE SIMU in version 4 and
today we are going to do a motor starting exercise in this case because the The working conditions
are the ones presented below when pressing gear, that is, a plus button s 1, the three-phase motor
starts 10 seconds later, it makes the investment, it automatically performs the reversal of rotation,
so what we are doing right now here or what is going What we intend to do is the reversal
of turns automatically well the second point says that we are going to signal the directions
of rotation of the motor The third point says that we are going to signal the engine faults in this case when
we are going to use a light signal and a sound signal here in our software what we are going to
have the elements that we are going to be using are going to be the following here we are going to find it
next in this case we are going to be useful raise a thermal magneto suite in this case we
will also use a thermal from the real one there are 12 contactor is a three-phase motor a plus button
suite normally enclosed and a push button suite normally open a pilot signal in this
case they will be good they will make two signals here we are going to rectify because there will be two signals and
we will also need an intermittent signal for the fault and a buzzer that is the sound signal
is for the fault and a timer which are the elements that we previously will be
using in our operating system so now we come here we are going to start making
force for it because we are going to look for our food in this case we are going to be using
power for strength and before I forget because I am going to leave
the power supplies over there the control scheme when we have to make that diagram so now
we come here we are going to look for the thermal magnet suite and in this case p ues here we are also going to
find our fourth heat engine and in here it is but I forget we are going to be using
more towards here it is here so we are going to leave it well here to make the reversal of rotation we are going
to need 2 contactors so we are going to go to the to the area to the icon the gallery where we are going
to find the contactors and we are going to have as that reversal of rotation we are going to have the need
that we are going to need the contactors to perform the typical reversal of rotation that we
already believe and consider Well, most of them already know how to do it, they can already do it and because we have already
practiced it on several occasions, now we come here in Cali to the icon where we have
the motors and in this case we are going to use the three-phase motor by common that we When
we have this that they attack well, here we have strength, we are going to start, we are going to go to the gallery
where the connection lines are, and we are going to make the connections that we already know
about our line. supply to our circuit breaker with circuit breakers suite then we
go to our contactor which is our first direction of rotation and we are going to go directly to the thermal relay
and the good relay we are going to the motor now we are going to do the reversal of rotation in the case with
this The other contactor that we have here, which is the one that we have considered for forgiveness for this
reversal of rotation here and well, we are going to do it this way, I am going to do it this
way, then we are going to do it here and in fact we are doing it and I try to go a little light
but I am not that fast with the machine and therefore maybe you are bored there
but I am not doing it this way because some subscribers have always written me who
say that the video class presented it He presented it already in the order and when it is finished and that he
did not execute it from scratch this I will do it from scratch we will start to name
here well first we will make the connection of the polarity ky the earth well now here we have
strength now we are going to begin to appoint in this case our directors of a
single director because I do not need to name him but if you want you can do it there in the
case of contactors as I have two contactors is the one number one for 0 km we are going to leave it like this
and the next one in the reversal of the turn will be a fall 1 a fourth motor as we only have one
motor because there is no problem well then now we will start with the control scheme we
will start with here around here at some point we turned the elements and then now
we start using or looking for the auxiliaries that we have in force in this case the auxiliaries
of the contactor drop me the km 1 and the auxiliaries of it the thermal relay also then we begin with
the protection the fourth engine looking for those auxiliary auxiliaries we will find them
here we come and I always use this double because here it presents me with the ease of contacting
the control act or the auxiliary 95-96 that is closed 97-98 that I have opened to simulate the beach
so now I will also look for the button that I will use to start and stop that this
scarce we will have the button closed to stop and the Open button for the ignition here now
we are going to look for the coils then we are going to look for some auxiliaries there but right now we are going to go to the
gallery of coils and signals and we are going to search well we are going to occupy a timer that
we are going to use we are going to occupy two coils this fact I am going to leave a coil here the
other coil here we are also going to use two signals two signals to simulate indicating
what is the ignition of each of the turns then we are going to use intermittent signals
for the light failure and a sound in that way here we have it here
then here I am going to put the signal of the relay the caem then I have about
me we are going to leave it here the lamp you are now it will be the lamp 1 green color here Now we are
the second of the second turn, this will be the m1 and a signal will indicate it, the lamp h 2
, we will leave it blue, it is all the colors, it should be green, but we are going to put
different colors there so that it can be seen. different and here we are going to leave the timer on hold that we are going
to explain the timer and these signals that indicate the faults we are going to proceed to put the auxiliary
in this case we need an auxiliary to retain for the interlocking we are going to put it here and now
we are going to start to put certain names in this case because this is the stop because it is the one that we are going
to occupy for the shutdown here we have the start of the system that is the ignition we are going to put it
as start and well this auxiliary will belong here m so that it does the interlock the electrical retention
of each m this would be the one that I join very well now the time that is going to be the time
well, we are going to use two auxiliary of the timer in this case we are going to look for
an auxiliary that is c I have been asked to do two jobs for me and we are going to do it this way then
this is going to be one and the other is going to be one that we are going to put here both will belong to timer 1
and we are going to explain how it is going to do the I work the timer in fact we are going to name the
timer that we have not named and well we are going to start making the connections to see the
shape of the scheme that we are making, which is the power scheme, then here we come to
our shutdown then we come to the push button On and here we come to the auxiliary switch
of the timer and in the timer because we are going to close the circuit here in being the neutral but it should be noted
that this timer is the one we are going to use we are going to use this coil to make the change of
direction turn then it means how good we are going to leave it here this also at the time
of the timer bbva is going to do the work of ordering to turn off one coil and command to turn on
the other coil when this contact is opened this coil is turned off It turns off the first direction
of rotation and when it closes in this other direction with 58, then the other coil will turn on and
in that way it will be doing the on and off work and well, we are going to
make these connections here From the signals we come here to signal the two directions of
turns that we have here in the case of the good timer we are going to make the electrical retention we are going to make
the connection of the electrical retention here we are going to make this other connection up to here from now on
to make the first tests because we are going to connect the timer to the timer and we are going
to connect it in this way we are going to leave the failures last to make a
previous simulation at this time I am checking to see if we have no situation there we are going to
see if the simulation does not give me a failure, we close the director so that there is electrical power
to the contactors, the main contacts of the km and well, let's see here then now
we come and We press gear, the first direction of rotation with its lamp turns on, but logically
we could see that I clarified because here I forgot to put the electrical retention here so it would
never work for me but now we are going to work for me I did not notice that simulation see
why you have to do preliminary simulations to make some adjustments well, having
in fact made that adjustment, although we do not need it yet we have not finished it we are going to carry out
a small preliminary simulation to see if we already have the most important thing we close our
director and now we are going to do a small demonstration we turn on as we can see
we have the first direction of rotation here we have the first lamp after the count passes at
10 minutes it should be turned off it should be kms dsk m 1 through this change through that
change that is here when that happens we owe this contact that is here helps us retain
the retention of this other of this other direction of rotation because if This retention ends
the moment we turn it off, the same timer turns off, the timer commands to turn off in the first
direction of rotation, the interlock is deactivated, so we have to send it to interlock with the
same timer, so here I think we already have it we are going to now simulate the different faults
we are going to put the controls further here we are going to simulate the faults that we have not connected
then we are now going to come straight to where we are going to connect the elements that
and we are going to use you for the simulation of the faults which in this case is a sound signal and
a light signal in this case we have these two situations here then we are going to see the controls
we are going to draw them here we have two pushbuttons just a stop pushbutton which in this case
is the stop is It is red and we also have a green start button and it
is the one we have called start here we are going to close the box so that we already have the
controls the controls c Complete now there this but now we are going to see if to simulate the fault h1 h2
this would be h 3 and well the color we are going to put it to the light signal that is red then
we are going to do a simulation now we are going to close the circuit breaker we come here In our
control box we press gear and as we can see the first receptive turn has been turned on,
some time goes by so that when that time is over it makes the change and to the next direction of
turn as we can see it has worked correctly now we come and stop the
system we are going to do another simulation we turn on and the time for the direction of rotation has not passed,
then we simulate a fault as we can see the system turns off automatically the system
must turn off now we are going to simulate we are going to turn on again we are going to simulate a
fault when already The following direction of rotation has been turned on, which is what we will always
do the simulations we must do different simulations in different It is events
to do the different tests all the possible failures that may occur in the system
now here the other direction of rotation is already on we have to simulate each failure and
as we can see the system has stopped well I think that Here it is working well but I do not know
the director now here and I think it is working well for us and we can see the time as
we can see time goes by when time passes the change of turn is made here and everything is
correctly where we have the system Well here the whole scheme is working correctly
so I thank all those who are following our tutorials at home
in one way or another and man I thank you for joining our youtube platform
and in one way or another because you are supporting us here We leave this exercise so that
you can see there if there is any situation that is different from the one you are raising here.
I would appreciate it because you let me know it with pleasure. Is this if I can help with pleasure
help you say goodbye to you professor Rainer as always wishing you all have a good day
