thanks for the replies.
beavs2112, it did that a few times but that is not the problem now.it is in the center of the arc now so it is not the hardware limits either. er2 means no pulse detected , obviously since the motor terminals does not put 36V , the motor does not moves either in that specific direction.
richyrich, no 4dtv neither an analog receiver. How I which I had it since I help a co-worker install and aim a 12 ft mesh dish with a GI analog receiver as controller and that old rusty Von Weisse motor moves the "black monster" without making any noise and effortlessly while my "new" system makes 3 times more noise. I measured 10.9V DC between the sensor terminals in the back of the controller with the cables disconnected. Are you saying it is supposed to be only 5V DC between both sensor terminals in the VBoxx II?.
Yes, sensor voltage, in the correct form, is 5 v DC normally, although I have seen some higher and lower when the cables are hooked up. Check your sensor (reed switch) at the dish. When it is in open condition, the voltage there too should read 5vdc on the Sense line. It should read this voltage with the wires disconnected inside also as you have said. There is also a 5 vdc terminal on the box. This should be marked for a hall effect sensor, and is not used if you have a reed switch on the motor. Hall Effect sensors use 5, and pulse, and ground. The pulse is usually marked "sense" because it really is a "if ground" detected, count, placement; of the counting devices inside the V box, and has very little amperage applied. Reed switches only use the 5 and ground, and if you hooked 5 and ground, then you've only blown your reed sw out at the dish, and only need to replace it to be in "auto" again...
Whoops, I'm trying to think too hard here, again. The 5 volts is on the 5v-11v terminal, used by only hall effect sensors, not used by the darm with the reed switch open/closed type counter at the dish arm...the "pulse" is about the "o i forget" volts, detection of ground applied and a reed switch uses pulse, or sense; and ground (pls/gnd) terminals. Applying the 5 vdc to a reed switch type sensor will fry it, no doubt. I think the voltage is 5vdc on the sense line too, but if you try to read it, it will short the line slightly enough to go to 0 vDC, and give you a funny reading on your meter, because that is what it is supposed to do. Man, I almost gotta be there to figure myselfs mindy out...
