I had a call last night from a company using Gizmos in their business. Last night, it got a little cool here in Minesota; down to 40-50 deg.F. *All* their Gizmos refused to run. Contactors pulled in, but moving the potbox produced no output at all from the Alltrax controllers. But if the car was left on for a while (30-60 minutes), something warmed up and they started working!
That's a weird one. I've seen things like contactors that got wet, and when it went below freezing they "froze" in the off position -- but it wasn't below freezing. I've seen electronics get erratic at very low temperature because they used 0-70 deg.C parts -- but these failures are occurring much warmer than this.
Anyone (particularly with Alltrax controllers) have any ideas? The cars aren't physically here, so I can't check things myself, but we could suggest ideas to try to get them going.
