Titanium Satellite Titanium ASC1 Positioner Troubleshooting

[jdavid22]

After receiving the shielded cable, I made the connections and I can say that the problem has been solved. I can go from 135W to 55W without losing count. I didn't insert the capacitor. I tested it and it worked fine, so I left it as it was, but I'm attaching an image of how I planned to connect it. Could you please tell me if it's correct? Thank you all.

Titanium, could you please help?

Post #9 should be a good ballpark. If you say your count errors are minimal or nil then no worries.
Here's a sketch to maybe help. I'm taking it you have shielded sensor wire.
Is the terminal on the motor assigned as ground? Is there a wire in it that at least goes to the motor case?
If the terminal is empty, use the ground terminal on the back of the ASC1. Use one or the other. I wouldn't use both.
The distance of cable could cause a "ground loop" and that wouldn't be good.

Post #9 from KE4EST:
"If not try putting oh maybe a 250-500pF capacitor across S1 and S2."
S1 and S2 are the sensor terminals. Where you just installed the new sensor wire. C2 in the sketch.

"and put a 0.1µF cap across the motor leads."
Explains itself. C1 in the sketch. Use non-polarized ceramic capacitors. NOT electrolytics.

"and maybe one of each to ground from the motor terminals."
Probably not really needed if you're getting no errors now. But he means in addition to C1, also add the same value capacitor from each terminal that motor power and C1 are populated with to the ground terminal.

My actuator gearbox had no ground wire in the empty terminal block screws. So I used the back of the ASC1 ground terminal to hook the sensor shield wire to. Currently the gearbox is grounded using a screw that goes into the casting and then is inserted in the once-empty terminal block cavity. And the sensor wire shield unhooked from the ASC1.
