Quest M3 PID
af
one.
I am new to PID but very interest to have PID and SSR installation, I
read the diagram from Arpi and not sure about the wiring of the SSR
direct to the heating element. Would the power from SSR to heating
element by pass the Amp meter ?
zb
Sorry I could not answer earlier. The Amp meter is only for analog continuous readings. The output of the SSR is digital ON/OFF (max/zero) and should not be connected to the input of Amp meter. The SSR output should be connected after.

My region is 220V. I am aming for OMRON SSR G3NA-240B (40A) and FUJI
PXR4, I have question about the SSR and PID.
1. How hot is the SSR? Would it be possible for mounting it inside
the Quest M3 unit base plate and attach a heat sink under the base
plate? Or would it be functional without heat sink?
2. For the PID, there are few options for the RS485 interface,(Modbus,
ASCII, Digital input, etc...) Do I just need the "M" options ?
Thx

My SSR does not get hot at all and (in my case) does not need a heatsink. But is is mounted against the wall of the external enclosure (with the PID).
The Fuji PID would need the Modbus protocol (RS485 option) in order to work with the artisan software. No other requirement is needed.

Thx for your reply, For the RS485 interface. I know there is interface
between RS485 to RS232 OR RS485 to USB, it is quite difficult to find
serial port in notebook, does the Artisan software support USB interface?
I also find there are RS485 to radio signal and radio to USB (Arduino
module), does this combination also work ?

This is the model I use:
HXSP-2108G USB 2.0 To RS485/RS422 Converter (with USB)
I think (not sure) that all PXGs come equipped with an RS232 port (uses a mini-stereo jack at the bottom). But you won't be able to attach it to a second PID unless you purchase the RS485 option. The mini stereo jack (RS232) allows you to connect only one PID (not multiple) directly to the PC.

my region.
Are you using 2 PID ?
zb
Yes I have a second PID installed. My first PID (PXG4) controls ET, meanwhile my second PID (PXR3) reads BT. The second PID adds some convenience.
The second PID serves as a digital RS232 thermometer (with LCD) and it can also turn ON/OFF a second device (maybe like a fan). Both PIDs are connected to the artisan software but they can run on their own without connecting to a PC.
Contrary to popular belief, a PID does not convert the roaster to a fixed 'automatic' device unless wired to do so. In my setup, I have the option to run the roaster using the PID, or to use the same original manual controls that came with the Quest M3. All I have to do is to flip a mechanical switch. At any time I can turn the switch and run the roaster in manual mode.

between the timer switch and amp meter for selection of manual or PID mode.
The M3 I have ordered has 2 K-thermalcouple (BT and MET / ET ). I will get
a PXR4 (with RS485 as PID) and a 2nd hand E5CN (with RS-485 and
thermometer), a USB2RS485 convertor.
Do you know if the Artisan software support OMRON E5CN and the daisy chain
devices work with the USB convertor?
There is more interesting RS485 to radio and radio to USB modules, this
could be a later stage modification.
zb
Artisan only works with Fuji PXR and PXG (with modbus protocol). Others PIDs will not work. OMRON E5CN will not work.

I have question about SSR and ammeter. Did you add the SSR before or after
the ammeter ?
If I add the SSR before the ammeter, would the switching current from SSR
cause damage to the ammeter.
I found it phyiscally quite difficult to access to the nut of the ammeter
which is quite inside and blocked by the VR, do you take apart the upper
compartment to access to the wiring?
Thx
zb
The SSR needs to be connected after the ammeter. Otherwise it would swing full On-full Off and it would be meaningless. I use the second ammeter output bolt (with nut) as a tie point. It was a little tight. But if I remember, I used needle pliers to reach to the nut. To access the wires, I made a hole (same size as the electrical box connector) in the low part of the roaster (plate pulls out), paying attention not to touch the heater element supply wire (the hole was close). I used a cheap step drill bit (looks like a cone) to make the big hole through the stainless steel at the bottom. I had not problem making the whole.
Cheers

bolt, the nut cannot be taken out as it was blocked by the drum
motor. I used a U shape cable connector to attach the cable to the
output and tie it back with the nut. Next step is the SSR and PID
box.
