Re: [ExternalEmail] Re: [4x6bandsaw] which version to get
¿ªÔÆÌåÓýThose overload relays are intended to be used with an external contactor that actually controls the motor I would not really want to use that overload contact to control any motor drawing over ~1.5A @ full load. Even then for proper sensing you ought to run your current through all three legs. In particular I would not use this one, since the design is intended to have the realy mount directly into the contactor. The three ¡°legs¡± coming out the top are not terminals and there is no way for you to connect to them. They are intended to slide into the contact terminals of a matching contactor. Also this rather suspiciously does not show you the FRONT of the relay, where the real manufacturer of those images is, and I suspect you would actually get something rather lower in quality. ? Here is an image that shows that style of relay as it is intended to be used. ? Here are a couple more suitable type solutions ? ? ? no endorsement intended. These are probably not UL or anyone else listed, but is a reputable manufacturer. {If that is actually what you get} Notice its price tag, and you would still need an enclosure. ? ? ?

Good info, thanks Alan, I'll follow that up. Arduino is cheap enough if from China, but not $12-cheap.? Arron, if your blade comes off easily, although it's a 'safety feature' it must be very frustrating.? It's probably in need of some tracking adjustment.? The blade should just skim both rear guide rollers and I suspect the lower and maybe even the upper is pushed hard into the blade.? Back both away until both are visibly clear of the blade and then bring them forward. Unfortunately that will upset your squareness so that will have to be done afterwards. Maybe the safety feature is worth putting up with.... You've revised my opinion of UL Jim, thankyou for that - jv? ? ? ? On Tue, 2 Feb 2021, 3:31 am Alan Muller, <alan@...> wrote:
