Topic: new to me PID second time sent (4 msgs / 129 lines)
1) From: petzul
Wow, the email I sent next got there last night. THis one was sent first.
The Postal Service just delivered a new, to me ,Fuji PXW-5.
The seller never answered me as to it's configuration, but I was able to 
get the codes off the side of it. It is a PXW5-RAY1-5V-D. This was on 
the label on the side, but there was another unreadable label stuck on 
over this one. Also it was manufactured in 1997, and has another 
marking- No. 727857T
I think this means that it needs a 24V ac power supply to run it, and 
that the control output 1 is Relay Contact, reverse action.
Does this sound correct?
Well, it would be better if I could just run 110 V AC to it, but I can 
handle using a transformer if that is what it takes.
I do not know exactly what is meant by the control output description.
Does this mean I can not use a SSR?
And I am not sure what reverse action means? Sounds scary, like perhaps 
things will be turning off instead of on. Do I need another relay to get 
it so I can use an SSR to turn on my heater ?
Right now it seems like I need to buy a whole bunch more stuff to use this.
Gosh.. so much to learn.
It seems like a nice unit though. It is in a rectangular box with 18 
screws on the back. They are all labeled by a diagram on the side. Now I 
just need to interpret everything.
Any ideas or suggestions will be humbly appreciated.
Respectfully,
PeterZ
Probably in way over my head, here in LHC.

Hi Peter,
I don't actually know anything about these things, but I was just talking
to Dwight of ttiglobal this morning about the various output options.
Reverse acting means for use with heating rather than cooling and is
really just a configuration default.  Relay contact means it actually has
a mechanical relay inside the unit, probably 2 or 3 amp, so it would have
to be used to control a beefier relay if you're going to drive a ~1500W
heater.  I wonder if that beefier relay could be an SSR?  Seems unlikely.
In any case, Dwight was very helpful.  Apparently tti even ships
controllers preprogrammed with bean profiles!  How can I resist?  But
first, I must disable that damned dirty thermostat...
Cheers, Clark

Hi Clark,
I only know about them what I have read on here. Never knew there was 
such a device before this list.
Thanks for the tip on calling ttiglobal. I will do that tomorrow. 
Honestly, someone else had suggested that, but these allergies have my 
head in a fog.
I need some definite tab A to slot A directions to hook this up. I will 
report back what I learn, and it may be lengthy because I need 
absolutely everything explained.
The vendor reported back to me what the part number is (PXW5-RAB1-5V), 
and it is different than the one I determined. Apparently that illegible 
tag stuck on over the one I read had significance. The only difference 
though is it has 2 control outputs instead of one (whatever that means). 
I thought it was raY1.
Mechanical relays are cool! Lots of clicking :( May have to rig it 
somehow to drive a SSR. Will learn that from ttiglobal. Maybe they have 
something I can use!

Still scratching my head, here in LHC.

Peter,
If you need lots of guidance, look at Murph's website http://home.flash.net/~jfmurphy/pidsilvia/. He has lots of pictures, great 
descriptions and a shopping list.  It helped me a lot when I PID's my 
Silvia last year.
Murph also has a "if I was doing it again" section with some good 
thoughts.  Based on those, I went with a 42" thermocouple.  I mounted the 
PID in a Radio Shack plastic box, which is stuck to the side of Silvia 
using doublestick tape.  A couple other goodies from Radio Shack -- I added 
an inline quick-action fuse, as recommended in the Fuji manual, and some 
spade lug adapters to the main power distribution point in the 
Silvia.  That way, power and everything came from the inside of Silvia -- I 
didn't have to run a power cord from the PID to the wall socket.  I went 
with the Fuji PXR3 from TTI Global, as many others have done.
On the Radio Shack website, the spade lug adapters are mslabelled as 
"Crimp-On Quick-Disconnects $1.69 Catalog #: 64-3064", but they've got a 
good description (1 female to 2 males quick disconnects).  The push 
on;  they don't crimp on.  This is a package of 8, 2 each of 4 different 
styles/shapes.
My Silvia runs 24/7 most weeks.
If I was doing it again:  I'd probably pay the additional $30 for the 
"optional digital input".  You can use this to activate a second 
temperature setpoint.  As I've read in alt.coffee, this would let me wire 
that input point to the Silvia's steam switch.  By flipping the steam 
switch, the PID would control the steaming temperature also.  Right now, my 
brewing temperature is controlled, but steaming is still controlled by the 
thermostat.
