Subject: 1 idiot trying to hook up a pid controller.
|
Here is my problem. I am an idiot when it comes to electronics.
I can build you a pc from sctratch no problem.
Wiring and diagrams and such not a clue.
So I had a fuji pxr3 controler hooked it up to a power cable and it
blew up.
Not wanting repeat the same mistakes again I refer to the more wiser of
you in the group.
I thought you could hook up a regular power cable to a pid and plug it
into the wall and it should power on.
Also I have an ssr. I understand one end of the ssr needs to be wired
to the pid that is all fine. There are 2 wires coming from my heating
element I understand they need to be wired to theother side of the ssr
as well. Can I connect them directly to the ssr? If so how does the ssr
get power from the pid? I know the thermal probe is hooked to the pid
input I am good with that.
Just missing some pieces. Someone please help a moron here trying to
get this right. I ordered a new controller with fuzz logic do I need
the ramp soak features yes no.
The cotroller can be configured reverse action so i do know what that
is about.
Thanks Jason Casale

That is good news.
Terminals on Auber will be numbered differently, but the idea is the
same.
If you are getting the LED to illuminate as it should, then the odds
are pretty good that the SSR is going to switch the heating element for
you.
But if it is still not working, there are a couple of additional checks
you can do on the SSR with a multimeter - keeping in mind that you are
dealing with line voltage that will at best give you a very nasty
shock, or at worst pay off the mortgage.
At least one of the AC terminals should always be at 115V (measured
relative to neutral). If neither is at 115V, or thereabouts, then you
are not getting power to the heating circuit for some reason that is
unrelated to the PID.
When the SSR is closed (LED on), the AC voltage across terminals L1 and
T1 should be more than zero, but no more than 1.6V. If you are getting
zero voltage drop across the terminals when the LED is on, then there
is no current flowing, suggesting a problem downstream in the heater
circuit.

Okay Jim here is what I have so far.
I bumped the temp on the controller higher that the read temp from the
probe.
The led lit up on the ssr remained there. The temp never went up on the
probe boiler reamins cool to the touch.
So the load part is not working.
Wondering what to do thanks jason

Jim thanks,
I bought an aubins controller this time
So I am not sure if the instructions you give will apply to the
controller I have now.
I did bump the controller temp up and the light did come on on the
relay ahh haa
Not sure if it will turn the heating element on or now I hope so.
I did wire. The the heating element wires to the ssr output one wire to
t1 one wire to l1
Does this sound right thanks jason

Well, a non-fried PID upon power-up is a good start!
If you have a multimeter, check the DC voltage across terminals 5 and 4
of the Fuji PXR3 (5 is the positive side). Should be at least 5V.
Drop down to *** if you are seeing 5V or more.
If you are not getting 5V or more here then check to see if lamp C1 on
the front of the PXR3 is illuminated. If C1 is illuminated, yet no
voltage across 5 and 4, then there is a problem with the controller,
perhaps configuration, perhaps hardware failure.
If C1 lamp is not illuminated, then confirm that setpoint (SV) is above
the thermocouple reading on the display and that configuration of the
controller is correct (I think heating mode is "reverse" action on
output 1 for the Fuji).
*** If you read 5VDC across output terminals 5 and 4, and if those
terminals are correctly wired to A1 and A2 (or whatever the DC
terminals are on your SSR), then LED should illuminate regardless of
whether line/load terminals on the AC side of the SSR (T1, L1) are
energized.
Let us know what you find out.

Thanks to the group for the help.
I am on my way but missing something.
I am extemley appreciative of everyone's comments and assistance.
I believe i have taken all the required precautions for safety and I am
following Jim's
exact order for hookin everything up.
I got a new pid connected it to power same cable it powered on and did
not blow up this time so that is good. I connected the omega probe
powered the pid it displayed the correct tempature. On to the next step
I took my 16 gauge wire and wired it to the pid ssr dc output + - To
the A1+ A2- on the ssr. I then plugged the pid into power again and the
ssr led did not lite up so I am assume for whatever reason it is not
powering on.
I then connected the 2 plain black wires coming directly out of the
heating element to the the T1 L1 side of the ssr. Powered on the pid
again and no led light on the ssr.
Any Ideas. Thanks Jason

JC -
You said:
"I then connected the 2 plain black wires coming directly out of the heating
element to the the T1 L1 side of the ssr. Powered on the pid again and no
led light on the ssr. Any Ideas. Thanks Jason"
This does nothing and, in fact, would have blown your SSR and opened the
circuit breaker (hopefully) if your pstat were still operative and/or hooked
up.
With the machine and PID unplugged, reconnect the wires to the heater. At
this point there should be nothing connected to the load side of the SSR
(terminals L1, T1).
Set the Auber PID up properly following its instruction manual. There
should have been two wires going to the old pstat. Assumming this is
correct, connect one of these wires to L1 and the other to T1 on the SSR.
If you need to extend the wires, use the same gage wire or larger.
Plug the PID in with the machine still unplugged. The LED on the SSR should
be constantly lit. Plug the machine in and turn on. Heating element should
power up. Set Sv on the Auber PID to desired value.

Have you programmed the PID to turn on the heat? If the PID isn't
calling for heat, it won't turn on the heat.
Once you have the PID powered up, the TC wired correctly, and the low
voltage side of the SSR running, you should start entering the
programming of th PID, consult your manual and swich it on/off
manually via the keyboard to check that everything works.

Ok, perhaps that is true. But anyone with burning curiosity won't be
put off by this sort of warning. Why not give some advice and help the
guy out?
I usually tell the difference between high and low voltage by whether
or not I can hear the corona discharge. That doesn't matter. It isn't
the voltage that kills. But of course everyone here knows that.
JC, it is true that you should be careful and take the necessary

Thanks Jim I did not even get that far.
I hooked an external power cable to the controller to verify it powered
on at the appropriate power terminals I believe 8 and 9 on he fuji and
boom.
That was where I was going to start as you reccomended.
my ssr is a rs1a23d40 standard zero switching ssr I believe
Solid-state relay (230v/40A out, DC in, zero switching)
I think I should be okay where would one perporate to get a safe power
cable for a pid?
there are four post on the ssr relay A1+ A2- is that the side where the
heating element needs to connect? The other side of the ssr is lables
L1 T1 That would logically seem to be the side that connects to the dc
ssr out on the controller do I have this correct.

JC -
No, you do not have it correct.
The terminals on the SSR that are polarity labeled get connected to the PID
controller in a "polarity correct" manner.
As the switching side of the SSR will be carrying the same amperage as your
old pstat and heating element, the wire gage size should be at least equal
to what exists on the machine at present.

In that case the unit was defective and you should send it back under

Nice loud explosive sparkling and scorched or vaporized wires usually
mean a complete short, hot to ground or neutral. If that is what
happened and you did have terminals 8 and 9, you need to remember the
most basic 2 rules of wiring anything:
1. Give every wire a very hard tug after attaching it to make sure it
is well connected and stays put.
2. Make sure the power is unplugged, physically disconnected, or
interrupted at the breaker (not just switched off at a wall switch)
when doing any wiring.

On the Carlos Gavazzi relays, A1 and A2 are the low voltage side, L1
is the AC line, T1 is the load.

It's nice to see someone sharing their knowledge freely. Maybe we can't all
be electrical engineers, but with insight like Jim offers & my trusty

randy thanks again for the advice.
I looked at that kit but it was meant for a sylvia not an astra.
You see I recently took appart my astra put it back together and am
ready for the pid part I have the probe installed where the pressure
stat used to be.
I can wire that to the controller no problems. I am just wanting to
make sure I get the power and ssr wired right this time any other
helpful suggestions would be appreciated.

Wow, you always see it in movies; I didn't know it could happen for
real ;-)
You probabluy connected one of the 10 volt DC outputs fronm the PID to
the SSR to the AC power and smoked the op amp.
The SSR is a four terminal device. The two AC terminals (switching
side) are connected like a light switch, interrupting the hot wire to
the heater you're controlling:
AC Hot SSR1 SSR2 Heater hot
o-----------------o o------------------o
The other two terminals of the SSR go to the approipriate terminals on
the Fuji -- do not connect them to the AC.
Finally, the PID is powered by an AC hot and common to the power in
terminals.
Hook the stuff up in the following order:
1. Power to the PID and check that it powers up
2. TC to the PID and check you get a correct temperature reading
3. SSR control side to the PID and check the SSR is switching
4. Finally hook the heater to the power side of the SSR.

I seem to recall that some SSRs will not switch unless the "switching"
side is connected at least to power. Does that sound right? If so, I
guess if step 3 fails one might connect power to SSR output before
retrying step three, then finally connect the load?

You can't do multimeter tests on the load side of an ssr, all you can
do is see that it switches a load. Once the control side is hooked up,
you can check that the current to it is switching using a multimeter.
The Gavazzi SSRs have an LED that indicates the control current.

Without a multimeter refreshing in tenths of a second, how can one
test whether an SSR is switching if the SSR does not have an LED like
the Gavazzi you mentioned?

You confirm that the low voltage/control side is working by measuring
that. Then hook up the load (or a light bulb etc) and see if it works.
My instructions were just on how to wire the thing step by step and
check the connections. One assumes the actual components are working
(at least until they don't).
That being said, I don't get the same "he's clueless" vibe as some
others from the OP. It sounds like hemay have hooked the PID to the ac
correctly and the unit itself had a short.

I'm sorry, let me elaborate:
Without an LED on the SSR, how could one confirm that the SSR is
switching without having gone through your "step four" first?
Thanks,

Right, many relays that switch AC switch on zero-crossings and require
power, or at least more of one than a multimeter provides. Also why
AC-switching relays are usually cheaper.

The problem is, someone reading this might do just that, and blow up
their SSR as a result.
Remember that the SSR is a switch, and you know what a switch does if
connected between hot and neutral, right? It is necessary for there to
be both power *and* a load, with the switch in series.
While helping people is commendable, I sure share Jack Denver's
reservations about doing it in an online forum.

Of course. But if the switch is just connected to hot like I
suggested, with nothing (no load, no neutral) connected to the other
side of the switch (SSR output) then I don't see a problem. But I am
no EE and am frequently wrong on my assumptions when it comes to
electricity, so would appreciate very much an explanation of why what
I said is wrong, if in fact it is.
(which I wouldn't doubt, I just would appreciate an explanation.)
Thank you,

Not only no problem, but nothing at all; with only hot connected, there
is no circuit, and the SSR will not be able to be activated. You must
complete the circuit with, as someone mentioned, a light bulb (as the
load) and a wire going to the other SSR terminal on the secondary side.

The above puts you in the category of folks who should not be doing

(review on my website). It comes with EXCELLENT, step-by-step

If you hook the wires to the proper connections, and if it is rated
