backup generator transfer switch Frequently Asked Questions
Question DPDT relay, relay emergency generator?
Hello, I have a functional device DPDT relay RIB (relay in a box) Here is the link for the relay: http://www.functionaldevices.com/building-automation/display.php?model=RIB01P is what I do: We have a generator support our servers, but not the kind that you can use a TTY (automatic transfer switch) Basically all I want to do is use this relay switch automatically power utility generator power when the magnet loses its power. Then, when the power returns, the magnet is automatically enabled to return to food service. Please look at my wiring diagram to see if I have configured. Please me advice and opinions! Thank you! http://i108.photobucket.com/albums/n12/mattmo91/wiringdiagram.png?t=1299485134
Some terms used to photo photobucket mark is confusing. That's what you need: Blu N / C = Yel generator NTRL Com = output, connect to the battery empty APC NTRL120 backup input. Org N / S = / Switch Network foodservice NTRL Gry N / C = HOT = Com Prp generator output, connect to entry APC battery backup HOT120 empty. Brn N / O = Network / Switch Energy Services HOT N / C / D input output relay links. Connections output relays are Com. N / C connection is normally closed when the relay is energized. It opens when the relay coil is ENERGIX. N / O is normally open when relay coil is energized. It closes when the relay coil is energized. These terms can be confusing to someone who is not accustomed working with the relay. The (relay in a box) = two coil connections son who are white / black must be connected to the switch. When power primarily on, the relay (in a box) of the coil is energized. The Yel Com = output, connect to the server entry and NTRL Org N / O = NTRL switch connected network. The PRI Com = output connect to the server entry in red and BRN N / S = HOT network switch is connected. You 're running on AC power. If a power outage, the relay (in a box) of the coil is energized. Blu N / C = NTRL generator and Com Yel = output, connect to the server entry NTRL be connected. The N Gry / Red C = Com = PRI generator output, connect to the server being HOT input.will connected. You are powered by the generator. If the server takes less than 20 amps to operate the (relay in a box), which is rated at 20 amps should be fine. If you do not understand my explanation, I'll draw a picture and mailed to you can watch. If necessary, click on my photo "Avatar", go to my activity page and email me. Ben
