(back) Subject: relay for blower From: "Kelvin Smith" <KelvinSmith@untraveledroad.com> Date: Sat, 24 Jun 2000 17:28:05 -0600   Hello,   I was just going to hook my blower to be turned on by a relay controlled = by a 5 v power supply instead of a normal light switch. So the coils on the motor starter are currently operated by current from one of the 220 leads which goes through a light switch on the console and back to the = connection for the coil on the motor starter. Now I have a small relay on a 110 circuit which is turned on by a message from the console. I want to use that 110 to run the starter motor, but I don't understand the connections for that. It seems like the current ought to go back through the circuit = it came on but it looks like it will go back through the blower's circuit somewhere. That is confusing enough, but someone may be familiar enough with this stuff to understand what I am trying to say.   Thanks, Kelvin

Normally, the way the starter is wired is that the coil = voltage is the same as the starter voltage. So, if the starter is = controlling a 220 volt circuit the coil voltage is generally 220. This = information ought to be able to be found somewhere within the starter; = generally on the coil itself.   The wiring from the coil that goes back into the starter is probably going = to a normally closed contact which is interfaced with the "Heater" = Elements. They are there so that if the blower overloads, the "Heater" = Elements will cause the NC contact to open and thereby disconnect the = blower by opening the coil in order to prevent damage (which is the = purpose of a Magnetic Starter). The wire from the other side of the NC = contact is then usually connected to the other incoming pole of the = starter.   If the starter is new, there are usually wiring diagrams included with it = which explain just how the various types of circuits which can control a = starter coil should be connected. One such configuration would be to use = push-button start/stop stations, while another, which is what you're = wanting, requires a maintained contact in order for the starter coil to = stay engaged.   This is probably somewhat cryptic, but hopefully sufficient in order for = you to be able to understand what you need to do.   Sincerely,   Richard Schneider

I took one lead from the power line that supplied the blower and hooked it with 1pair 14 gauge insulated wire to the switch. It =   turns the blower on and off just fine by supplying or cutting off the = power. I also have another light switch for the rectifier and a third one for = the power supply that runs the Z-tronics relay.   Bart Kleineweber prinzipal8@hotmail.com http://www.diyapason.pipechat.org/webpages/kleineweber/ ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
