(back) Subject: Remote Blower control From: "Robert W. Taylor" <rtaylor@socket.net> Date: Mon, 3 Feb 2003 19:53:49 -0600   With all the recent chatter about blowers, I would like to hear from the group on various methods of low voltage blower control. I would like to control the blower from the console and two pipe chambers. Are there any systems readily available?   Bob Taylor

If you have a motor controller with magnetic contactors (and the associated ON and OFF buttons), then it might be possible to wire sets of those buttons in parallel (or series, as appropriate!); the contactor's "instruction = manual" may describe such a scheme.   I don't know if it would be necessary (or desirable) to have some sort of lock-out so that two people wouldn't be able to get into "remote control battling".   For a smaller situation (low hp blower, etc.), I've wondered if an RF remote control might not be workable. There are such devices rated for 240v and "enough" amperage (20-ish), and if a Variable Frequency Drive is used to power the blower (thereby gaining a slow-start mode), that might prove workable. For example, Woodworkers Warehouse lists remote controls for operating the shop dust collection system. They are rated for 110v/15amps and 220v/20amps (for a maximume of 3hp). They also sell extra transmitters. "One would think" that such a device would be useable with organ blowers (up to the rated capacity). Would one be correct?

If i am not mistaken it is based on the X-10 systems for a home. And it runs the 3phase dust collector.   Depending on the size of the blower, etc an electrician might be able to wire in or adapt an X-10 system to turn things on and off.   David

Any blower which = runs via a contactor relay should be able to have multiple stop/start stations, =   up to and including a wireless remote control such as X-10.   Personally, I don't think I'd want my home organ blower controlled by wireless remote...and I know I don't care for having the shop dust collector triggered that way. (Seems as though ever since we got that thing rigged into the dust collector, it occasionally just starts up by itself, without anyone having pushed a button...god only knows what stray signals it is picking up, or from where...!)   Tim (who takes pride in the way he runs wires, BTW. The world has too damn many remote controls. <g>)
