[TowerTalk] Prosistel 61D

[tony.kaz at verizon.net]

Hi Dave,Jeff? At Green Heron? If this is whom you mean, I agree that he gives excellent advice. The controller is fine. By bypassing the controller and feeding 12V direct to the rotator motor, I proved most likely the problem is in the rotator.By the way I use GD Everywhere in several situations here. They work well and Keff was very helpful to get me set up properly.
Merry ChristmasN2TK, Tony

I have had the 61D for several years and it was worked well. It is turning an original SteppIR MonstIR. I have a Green Heron RT-21 with the GH pot in the 661D. The other day when I went to turn the antenna nothing happened.I tried using a 12V supply. Same problem.When I try to turn the antenna, I get an "ERROR  NO MOTION" .Current draw is 400mA.I am feeding the rotator with three #14 wires for CW, CCW and GND.Since this problem occurred, the antenna has been slowly moving in the wind from 280 degrees to 231 degrees - both actual movement and reading on the controller match. My thought is the motor's worm gear is not engaged so therefore it can't act like a bake.  Is it possible the motor is running fine but not engaged with the pinion gear?  Is 400mA the correct current?
Any thoughts or ideas before I climb?ThanksN2TK, Tony
