Lightening? maybe a bad sensor on the SW. Mice? You might be able to Meg the Xformer. (Be careful). might be a bad contact. good luck

Subject: [RE-wrenches] Overcurrent error SW4024
From: mac Lewis <[email protected]>

Hello wrenches,I have a customer that I have been working with over the phone. He has a SW 4024, with a T240 transformer feeding a 2 HP well pump on a timer. The system has worked well for years, but recently, he has been getting overcurrent errors when the well pump starts. It's not every time, but about every other time. He also did an experiment where he turned off the well pump, and gets the overcurrent error just energizing the transformer. Does this indicate the transformer is failing? What are other explanations for this behavior?Thanks for any advice--Mac Lewis"Yo solo sé que no sé nada." -Sócrates
