hi everyone. thanks in advance for the help. I'm an electric noob, but I've built a an electric rims tube/natural gas hybrid system.
i was brewing yesterday and I ran into a problem with the reading from my RTD in my RIMS tube. It was reading really high. at first only about 30 degrees high, then after connecting and reconnecting the cable it read in the 600s or 700s.
Here is what i'm using
1. Auber pid - 2352 for SSR. It is set correctly for RTD instead of thermocouple. Set with parameters from here: https://www.homebrewtalk.com/f170/auber-2352-settings-programming-instructions-305710/
reds are connected to 3/4 and white to 5 per instructions
2. Liquid tight RTD - http://www.auberins.com/index.php?main_page=product_info&cPath=20_15&products_id=246
3. RTD cable and connector - http://www.auberins.com/index.php?main_page=product_info&cPath=7_35&products_id=269
I contacted auber and the first step of trouble shooting was to put a jumper between 4 and 5 on the PID and reset Sn to 0 to set it back to thermocouple. It read at about ambient - around 70F. Does this eliminate the PID as the problem?
The second thing they had me do was to test the resistance on the RTD. I took it out of the RIMS tube. I used the continuity function on the ohmmeter to see that pins 1 and 3 are red, 2 is white. I get the beep for continuity and when i test resistance across the 2 and 1 or 2 and 3 I get resistance in the 150-180 range depending on how good of a connection I can keep with the probes. The setting on the ohmmeter i used was 200ohm.
Am I correct to assume that this rules out the RTD as a problem?
Next I tested the connector part that connects to the PID and the male connector that goes on the outside of the control box. I confirmed that there is continuity between all three pins and the leads that connect to the PID.
Am I correct to assume that this rules out the male connector and the cable that connects to the PID as the problem?
Lastly I tested the cable. I pulled back the female connectors to expose the pins and the cable that was soldered. I used the continuity function to test if there are maybe breaks in the cable or something wrong with the connector. I tested pin 2 (white) and got continuity. I then started to test pin3. when I tried pin 3 to pin 3 (both through the connector and just via the soldered joint on the inside of the connector I did NOT get the beep to signal continuity. But when I touched pin 1 to pin 3 on the other side of the cable I got the beep. This was true on both sides of the cable.
Does this mean that the cable is bad? It is a steel cable with a teflon coated white/red/red cable inside. It has definitely been rolled up and possible kinked. What type of continuity is this cable supposed to have?
Thank you all for the help. I want to make sure my thought process is right before I start ordering new stuff from Auber.
