Solenoid Whack a Mole

Hi, I'm on day 4 with my Yardian Pro. Here's my experience so far, regarding Yardian's ability to scan and/or open/close solenoids:

Day 1: No solenoids found. I tried 20+ times and not once were any solenoids detected.

Day 2: 6 of 7 solenoids found. Only zone 3 missing. Scanned multiple time with same result

Day 3: No solenoids found multiple times. Had a maintenance guy replace solenoid for zone 3. Multiple scans with zero solenoids found, then magically all 7 show up successfully.

Day 4: 6 of 7 solenoids found, only zone 2 is missing now...

I have no idea what's going on, but I find it highly improbable that the issue is related to my wiring, because switching wires for zones still results in the wire plugged into zone 2 not detecting the solenoid, however, when the wire is moved to its original slot, it's detected again (at least when any solenoids are detected, but scary to me that half of the time none are detected).

Please advise, Yardian Pro Id is CA824D6A running latest firmware 6.12.220.

Thanks

  Hi Jeff,

  Please send an email to support@aeonmatrix.com with your mailing address. We will send you a replacement and see if it's the controller issue.

  Hi Jeff,

  Thank you for sending us 2 of your solenoids.
  I would like to post the test results here so it may help other people with similar issues.

  Solenoid #1 (2 wires with similar length) tested 54.1 ohm and it can be detected by the Yardian (Pro).
  It's been running well for 3 days.

  

   

  Solenoid #2 (1 shorter wire and 1 longer wire) tested 7.42 mega ohm and it can NOT be detected by the Yardian (Pro). However, the resistance is measured 46.9 ohm the second day and it can be detected now!

  

  The resistance changed from "open circuit" to within normal range.

  

  We also found that the wire splice cap is filled with mud and this might cause issues when it's buried.  

  

   

  I think this explains why you get different results while scanning.
  The resistance changes! It's recommended to replace those with issues.
  Thanks again for working with us to identify the issue.
  We believe the results can benefit other users as well.

  Best regards,
  Joseph
