Low Voltage Transfromer Question
I bought a hosue that has a low voltage outdoor lighitng in the
backyard. The wire connects to a Toro transformer that has an eye on it to sense when it is dark and turn on the lights. There is a switch on the transformer with the settings DD 4 6 and 8. Does anyone know what those settings mean? Right now, it is set to 6 and when it gets dark (or I put my hand over the eye) the lights initially blink on for a second or two before they go out. thanks! |

DD would be dusk to dawn and the numbers are probably settings for how many
hours it should stay on after dusk wrote in message oups.com... I bought a hosue that has a low voltage outdoor lighitng in the backyard.

hmmm... I was hoping that the switch had something to do with voltage
and that's why it was shutting off; If that's not it, what would be causing this behavior? It goes on for 2 seconds then off. If I unplug it wait a minute and plug it back in, it again goes on for 2 seconds, then off. Any idea? thanks! |

If this is during daylight, that would make sense. When you first apply
power to a photocell, (the thing that turns the lights on and off by sensing light) it is in the closed or on position, it then senses light and turns off. wrote in message oups.com... hmmm...

According to :
No, it's at night, pitch black out... You've left it alone for a full 24 hour cycle, and it doesn't come on and stay on (according to the DD/2/4/8 setting) consistently on its own? [I ask, because sometimes the electronics in these things will act wierd if you try to "by hand" activate the sensor - time delays, hysteresis etc.] You may be seeing an overcurrent trip. Count up the number of fixtures, and, after multiplying by the wattage levels of the lamp, is it less than the rating of the transformer? [Most LV bulbs/fixture/transformer "kits" use 4W bulbs, and can be upgraded to 7W. High wattage units (10, 20 and even 50W) are available, but these are usually pretty obvious (usually "pro grade" metal fixtures, sometimes different bases, more serious enclosures to deal with heat etc). Most "kit" transformers are around 60W.] The other possibilities a - short in the LV circuit. Try pulling all the bulbs (leaving one in) and see if it still trips. - defective transformer. The electronics in these things sometimes fries. -- Chris Lewis, Una confibula non set est It's not just anyone who gets a Starship Cruiser class named after them. |
