Sending the ASC1 into retirement?AJAK

[Magic Static]

Magic Static, maybe you could share scope captures of your current switch project so we can see the current cycle rates and noise levels? Maybe comparison with a G/V box in operation? Maybe other members might have observations on something that we have missed.

The current switch looks like this on the VBox X

With the ASC1 we see this.

My theory on this is: The difference here is the voltage to the motor supplied by the two controllers. The higher voltage from the ASC1 changes the load on the motor and the timing of the commutator changes. This increases the strength of the RF spikes produced by the collapsing armature coils. The ASC1 appears to enhance the noise issue here, but is not the cause.

You are probably right. It was face down in the dirt and I measured roughly across the back. I was sure it was more than 8'. It is a Model # AP2028

Yeh, probably an 8'-6er. I get excited whenever I see mention of one bigger than that, they were listed in the old BV literature (@9'-6) but must be pretty scarce.

Damn shame the one you found was bent, even at just 8'-6 the BV solids and perfs perform close to or better than some 10 footers.

That should be easy to check if you have a 4 ohm 36 watt resistor (or a rheostat) you can put in line to drop the voltage to 24 volts.

Were these scope captures taken with any capacitor filtering like your earlier post with 1, 2 or 3 capacitor designs?

Yes this has a cap on both circuits as seen in this picture http://www.satelliteguys.us/xen/attachments/andagain-002-jpg.98934/
So it is using the single cap design as you recommended after reviewing your installer notes. and one on the sensor circuit itself.

I love that you have setup the ASC-1 with its own accent lighting.

I say try a low pass filter next.

 

[ynnedibanez]

i would go the nuclear route and do the 3 cap setup on the motor and a r-c low pass filter on the sensor wires right next to the asc1

Hello

the entrance should be queried at least 2 times in a given time. If the pulse is too short it is not counted. So, we have solved the problem at controls of machines.

I'm still testing another solution with a reed relay.

I looked at that and while it seems a very simple thing to do, the mathematics involved to figure which resistor and cap to use is beyond me. And I wonder how the ASC1 will respond to a triangle wave.

Welcome Ponny to SatelliteGuys!

We look forward to your participation and input.

Hello

You can see my solution that works 100% excessive at this link. Here also the wiring diagram is included.

The converter can be used for optical sensors and also for the noise suppression of Reed sensor.

The Reed relay represents a galvanic isolation for the interference in this case.

In the shop of satshop24, you can find it at this http://www.satshop24.de/satshop24_s/wandler_von_optischensensor_auf_reedsens.html

Hallo

in der Anlage die komplette Datei in den Nachbau der Schaltung. Schaltplan und Vorstand wurden mit dem Programm "Eagle" erstellt.

Wow that's an expensive store! 298 euro for an ASC1 shipped? Must cost a fortune to ship over there. The reed relay looks good

Nice,Ponny,Brian ,care to comment on Poony"s response,as to the asc1 fix,dying to hear your response.

I haven't seen this optical adapter before, but it looks interesting!

Ponny is an owner of SatShop24 and has some very interesting projects and videos on YouTube. He hosts an annual satellite weekend that draws hundreds of hobbyists.

I was just wondering,Brian Thanks

Not sure what comment you wanted to hear, but I think it is very awesome that an optical sensor convertor was created specifically for the ASC1! Double credit for the same device addressing excessive noise on a reed switch circuit!

Maybe this simple circuit may be the answer for your AJAK with any type sensor.
