welcome to industrial challenge what we're looking at today
Hayers eFIXX we're looking at control stations from Hylec
key switches etc and from personal experience I noticed this box here at the front and what
size holes would you need to drill in this box in order to facilitate stop buttons start buttons and
key switches Routledge eFixx well that would be uh 22 millimetres Gary it would be 22 millimetres
and why is that such a painful experience possibly to electricians because 22 millimeters is the size
you're not likely to find in an electrician's hole saw kit now you're likely to find 20
25 mil and you're probably walking around looking for a plumber to get a 22 mil one
that can be a painful situation we don't want uh we don't have to go to the world of plumbing and
if anyone knows why all push buttons regardless of the range we've got this range from Hylec but why
they're all 22 millimeters drop a comment below i'm sure there's an interesting bit of history
but we can make your life a little bit easier today because we're not going to be drilling holes
we're going to be showing you some of this range from Hylec that's pre-assembled
and what can you get gary you can so if you look here they've already put the 22 mil holes in
and put a stop button and a start button in there already for you or in this one you can put your
own buttons in which can you have yeah well you can have you can have the four buttons in there
but you're right there come a lot of them come pre-labeled you've got start and stop you can have
up or down all right i can have forward or reverse and obviously you can have a popular emergency
stop all pre-label but perhaps you've never you've never experienced the world of industrial control
stations before so let's have a look inside to see what's in there we've got a rotary activator
switch here good thing on the highlight range it comes with two contact blocks are normally open
and are normally closed so here's our normally open one you see the green flag appears when
the contact is made and we get continuity and then obviously goes open circuit when we
turn the actuator to the other way and there's our normally closed contact block with the red flag
okay so what happens if i wanted to replace that or take it out guard now easy is that
i remove the switch assemblies it's just a case of simply moving that operating lever at the top
and then you just pull them off and yeah so a lot of these units have
an older designs you might find a screw there that obviously that is a little bit more complex
what about terminating conductors into those themselves okay standard across all sort of
uh industrial control stations there's normally room for two uh two conductors per uh per terminal
no doubt there'll be a bit of feral action coming up here isn't it here we go that sounds like a
feral so there's our first conductor there's a little metal tab across that uh across the screw
conductor so it's quite not liable to damage the conductor so again two ferrules in there
and then just tighten them up with the screwdriver okay so makes a nice uh firm connection and
ferrules are always better we do like a fairly efficient i'm sure as we pan back now we're gonna
have a bit of feral action are we oh there you go thank you very much why would you wanna take
me next time okay so let's have a look how you might have to change the actual actuator itself
so here's an emergency stop you notice there's a tab on the side quite important that because
obviously when you reset an emergency stop you've got to rotate it and that stops it
rotating unintentionally so again just drop that through and tighten up the lock ring on the back
and here if we want to actually replace a contact so a lot of the time it's very easy
just unhinge the contact from the top bit like a din rail component oh wow bring in
a replacement clip it in at the bottom and just click that into place and that was simple then
so we took a look at an emergency one now with a contrast colour of yellow with a red stop button
what are the colours they come in routely g-fix can get them in gray and black combination or a
grey on gray or a black and black if you want to go absolutely wild okay let's see how we fix these to
the fabric of the building so i'm going to mount the back of the enclosure to in this case the
wooden wall you notice that the four fixing points gordon are on the outside of where the ip rating
needs to be kept for the enclosure yeah it's a a great feature that's what means obviously your
mounting arrangements are outside of the IP rated area so you're not going to interfere with that
as you mount it to the wall so mounted in all four corners before then we look at obviously
installing the gland into the box itself afterwards so next up we've got a gland what's
really important about the gland gordon okay we've got the all-important o-ring seal on there as well
so we're going to make a good ip rating it's threaded and it's going into a threaded entry
that you've pre-drilled out with the required 20 millimeter hole yeah it means you don't need a
lock nut or a lock ring and then just nip it up remember you want to maintain that ip rating of
the enclosure before we go on to the the next bit which is having a look at this raised edge
here gordon what's so important about this well so that's the two parts of the gasket
so you've got your raised edge and then you've got that nice gasket silicon gasket at the front
and they just go nicely together four screws to keep it in place they're held reasonably
well in place they're not going anywhere okay and then yeah just tighten up all four
before we'll have a look at the um stop button itself so just nip these down and these go down
relatively easy and maintain the ip rating as the two uh front and back marry each other together
and just finish it off with the last one and then got the stop button i got good
thumb with this so you know what's gonna happen now gordon you're gonna push it
yeah and you see it locks down in order to release it have another go gary i'll have
another go treat yourself treat myself yeah here we go bam yes i like that standard arrangement
so you mentioned ip writing there but what ip rating are they available in
Hayers eFIXX uh ip56 and ip66 nice brilliant answer and obviously, that depends on the type of switch
you got obviously the difference between just the regular push buttons and those turn switches
as well well a bonus question since you've got that one right and what material are they made
um we're going with abs oh well done you must have he must have read this data she
even experienced the product gary so your next bonus question gary what does ABS stand for we'll
need to confer i haven't got glue it's a long chemical name can you remember it that's very
long chemical name really we don't care okay uh we don't know that's the right answer okay
thank you you've seen we've had some fun with these buttons aren't we gordon but
what can they actually be used for okay this is apart from pub quizzes actually and uh yeah
industrial challenge yeah this is actually a palm switch so say you had a gloved hand or something
like that but you can also use them with your foot okay so they're a foot and a hand switch okay
so turning on and turning off obviously identified by color as well and black as well you can never
you can have a black button okay what if i don't want a button on it well you can't just buy the
the box itself and we have looked at the hylic enclosure range of this forms part of it so you
can have this yeah blank you can you can drill it yourself if you want to get your whole saw kit out
and obviously they come in two different depth options as well so depending on the wiring system
if you want a bit of extra room to put some other components in there the control system
for highlight we've had a small look at it today we're always interested in your feedback which
type of emergency stop buttons key switches and start buttons are using are you using the
one from HYLEC please leave them comments below and we'll try and get back to as many as we can
