PID showing ORAL and no heat

[beersohard24]

Hello.

See photos attached for reference
My problem is kind of two fold - Right PID showing HOLD/ORAL -343 and I cannot get my system to heat.

Background: I purchased this setup from someone who had never used it. I am also new to electric brewing and by no means an electrical guru.. hence my post.
First batch I was successful up until I shut off the heater, and once I attempted to turn on again immediately after shut off, heater would not heat back up.

Troubleshooting I have done:
The 2 RTD wiring harnesses I have work on the left PID. (I get a temp reading).
I re-soldered the PID wiring to the 3 pin xlr that enters the control panel, as I noticed it had broken.
Verified continuity from xlr male end up to wires in terminals at the PID.
Removed and reseated the PID.
Read up on and double checked PID settings. (see below).

Alm1 280
Alm2 0
Hy1 9999
Hy2 9999
Hy 0.3
At 3
L 350
P 0
d 3
t 2
Sn 21
dP 0
P-SL 0
P-SH 2500
Pb 0
oP-A 0
OutL 0
OutH 100
Al-P 17
Cool 10
A M 1

Thank you for any help! Hoping something easy that makes me feel like an idiot and ready to brew!

What are the manufacturer and model of your PIDs?

I know for some PIDs, the "ORAL" indication means that you do not have a properly connected temperature probe on that PID. So, I would focus on temp probe connections on the PID that is showing "ORAL".

Brew on

The PIDs are AUBER SYL-2342P.

I can use each temp probe on the left PID and get a temp reading. The right PID shows HOLD/ORAL -343 regardless which probe I try. I also verified continuity on the 3 pin connections all the way to terminals 3 4 5 on the PID itself.

So I am wondering where to look next if I have a good connection and good temp probes but the PID still shows HOLD/ORAL -343?

Verify that the correct input device is selected, like RTD, TC, 4-20 mA, etc.
Edit: You selected the correct input device #21=PT100
I downloaded the manual, and the last page has some interesting info.
Compare all the parameters from the working PID with the non-working.

Yes compare the Sn values between both PIDs.

Also, I would guess that when you tested the temp probes and wires against the left PID, that you used the same panel port connected internally to the left PID. You could try disconnecting the two red and one white wire at 3, 4, 5 and switch those to the right PID. The order matters. On your right PID, there are red, white, and blue wires, it seems a different bundle of wires was used there between the port and PID. (Maybe thermostat wires.) It's possible those red, white, and blue wires are not connected properly or perhaps soldered not so good. I would also trace the R, W, B wires to the connector on the panel and make sure they match the configuration exactly as the other one. I think the two red ones are interchangeable but not the white one with the reds.

If the panel port is female, it could be gunked up or the connection is worn and/or slightly loose. I have the cheapest ones from Auber and these issues have affected readings. I've cleaned them with a little isopropyl alcohol in the past. If you bought a new port, it would have the correctly colored wires preattached. You just have to be careful ordering from Auber as there are slight variations, I'm not sure if the panel connectors are always female for instance.

Well it was the PID.. I did swap the wires and the issue did not move PIDs. Kinda verified it for me. I emailed Auber directly and I was instructed to check the resistance of the wires. Quoted from Auber for measuring resistance between the RTD wires "you should get around 100 Ohms between A & B, A & C, about 0 between B and C. Then connect A to pin 5, B to pin 3 and C to pin 4." My left PID was in that range, and the right not. I installed a new Auber SYL-2352 SSR and it works. Although it does show a quickly varying temp 84F-87F moving kinda quick. Wondering if that is a programming thing? I also did not do a wet test with heat but will shortly.
Thank you guys for all the help here, much appreciated.

Likely a poor connection or loose wire/hardware. Check for corrosion on the connectors, poor or loose connections with the wires. Small variations in circuit impedance will cause the PID to indicate temperature swings. It's possible, but not as likely, that the RTD itself is faulty.
