so in a previous video presentation Matt Gary and myself had a little look at wiring up a direct
online starter really helpful information especially for AM2 and AM2S so if you've
got that coming up go and check that other video out but what we're interested in this
video Matt is a little bit of a variation on the theme of the direct online starter
this is great this is fantastic if you've got a direct online starter exactly where it needs to be
close to the motor and you're going to operate it from that position but if we want multiple
positions of operation off we want to operate it from some distance away we need to start thinking
about wiring in a remote start stop connection yeah so how do we go about modifying our existing
circuit to connect up a remote start stop okay and Joe so it's it's really quite simple okay
so like you've said here you've got your remote stop starter thank you i've also put in a remote
stop and another remote stop down here brilliant okay okay just just just to basically show how
how it all um operates it's really important also to say that you can have a remote stop by itself
yeah but you can't have a remote start by yourself right simply because you must be able to stop it
from a position where you start where you can start you know on a convenor 10 meters away
and then something goes wrong you have to run that machine's going to the stop buttons can be
um can be placed anywhere fantastic so we have to slightly modify this only very slightly
basically we just disconnect this connection here that goes down to the stop button so it's
this link then we must it's only a small wire actually physically you just have to remove it
and that's absolutely critical isn't it if we don't remove that then actually this won't work
and you might be hitting the stop button particularly and it won't
yeah so again like we said with the retaining contacts number 13 and 14
they're in parallel with the start simply we just carry this on to be in parallel
with this one so again you just connect that one to there yep and then on this one
i'll come through here yeah so as you can see that's in parallel with this one yeah and so all
three connections are in parallel fantastic and even before we start wiring up the stop circuit
you can actually already see how that's going to work if you push that start button
it brings on the coil and if you press that start button that's going to bring up sources
as well however it's this connection here that's which is actually going to stop it from working
so like i said so this so we've got a permanent live connection up here we've got a permanent live
connection here and now we have a permanent live connection here sure the key is now we need to
link out the normally closed stop switch and that must be done on this side of the circuit yep okay
it's no good doing it from this side to there it has to be done on this side from the side that's
not normally live sure so again that link is just a small wire going straight down okay okay and
then from the stop button from the other side of the stop button that then just comes straight in
to there right and actually if you look at that the normally closed switch is wired in
series in series with that normally closed switch right so start buttons in parallel yeah and the
stop buttons in series like that and it's nice as well you can see if if this was very very remote
we've got three conductors that's what we're looking for between the two connections yes
in some cases you might you might think you need four conductors but you only need three conductors
because of that link wire yeah and like i said previously if you've got 10 amps of current
flowing through here and you you measure 10 amps there you're only going to have
milliamps flowing through this because this is only energizing the coil so it's only whatever
current this is drawing yeah which is pretty small which is small and that means this what
these remote stops starts can be quite a distance away with and only be wired up in small wires
so that's just the remote stop start button yep but i just want to bring in
really simply how you bring in the the additional additional stop buttons on there so you might
have multiple stopping points around a workshop or something like that a conveyor belt system
only start in one position that can can be stopped anywhere so again
this one everything is just wired up in series
okay got you so we've got one there the normally closed stop button here yep we just simply come
down to the another remote stop button here okay yep and then as it comes back in to the
direct online starter it then ah right just goes into there and again if we trace that round we can
see that we're going in series through that one in series through that one in series through that one
series through that one yeah yeah brilliant that's really clever i love that yeah so i've known
i've seen before 100 you know 100 meters of cable all just wired up in a very small sort of tri
tri-core flex cable and it's only one mil and it's controlling maybe a load of 10 amps something
else i'd just like to bring your attention to these contacts mystery contact we've not done
anything with that okay so what they're going to be for these are labeled uh numbered 97 98.
every every overload relay has them and these are for maybe if we had an indicator lamp oh okay okay
so in this case then we would need an indicator lamp somewhere yep so that can be situated um
anywhere anywhere you want basically so if we was to say have an indicator lamp down here yep okay
and what we need for that then we need a neutral obviously go into it
so again it's important that the neutral would be coming from
this connection yeah so again that would just link across all the way
down to there okay and then we take a live feed again a permanent live feed so it starts to become
a little bit messy with all the wiring in here but i think it's quite simple
yep goes into again it doesn't matter if it goes into 97 or 98 and then it comes out of 98
i see and then that goes then to the indicator lamp so let me make sure i've just got this right
so in the overload this contact is normally when the system is healthy yes when this hasn't tripped
that's connected and that's disconnected so if the overload should operate so if the motor jams or
starts to draw too much load for some reason the overload will trip that will disconnect the coil
which will obviously disconnect the contactor yeah but at the same time that will close
and connect that indicator lamp up so that would show the overload has tripped so it's not just
a case of the contactor has been turned off no no definitely not just turned off the overload
has actually tripped so you know there's a problem with the circuit and it's not just
someone pressing the stop button by accident or something right and like we said normally
closed normally open yep and they're both in reverse operation so as soon as that one
goes out that these are interconnected somehow and so that one will go from a closed position
to an open it goes from an open to a close fantastic and then the indicator comes on that's
brilliant it's really nice the way you built this up max we've gone from you know a fairly
simple circuit that we could trace and if if we'd started with this you'd sort of look at it and go
you know what's that all about but actually just by taking it one conductor at a time
you can very clearly see where it goes and i think that's quite an important tip actually
when it comes to wiring up direct online stuff so indeed any complicated circuits or control panel
pick a conductor and follow that conductor along then pick another one follow that conductor along
and that will help help you with your wiring as well yeah i mean it's it's in industry
there's other things that can go on with one of these and especially when you go up to one
and you can see multiple wires going all over to time switches as well but yeah
the basic operation of a to get a motor working is is through a direct online starter and yes it
looks more complicated but in reality in in actual it's not that complicated as long as like you said
you just take it one conduct at a time and you think about what you're doing as you're following
as you're following the circuit through break it down into stages yes fantastic well thanks
for sharing those variants with us matt really appreciate that that's good and i think we end
this video in the time-honored fashion yeah yeah okay we hope this video has been really
