This Is News To Me. Stab HH100

[Captain Jack]

He seemed like a nice enough chap when I visited him in Bristol maaaany years back and had good service from him. But it looks like he has some bad publicity generally...

 

[RustySpoons]

Ok, my dish is on the bracket now and messing around with the motor.
If I use my satellite finder to send it to its limit, east or west. One of those it will send it back to it's last position if I let it go all the way and leave it.

I think this might be how they work then, here is a video of mine:

 

[RustySpoons]

Can confirm, since I "Cleared Limits" the motor will go to 70 East, hit the hardware limit and return to centre.
If I set a limit of say 65 East/West it wont do that and it saves it.

I have the motor off the bracket and on the bench, hope this clears everything up.

Yes the Stab rotor does do the return if the receiver is running USALS (official or otherwise), though return to zero (or last position) it is not within the DiSEqC 1.2 Eutelsat protocol and should not occur.

Did you try it on both options as per TJs tests ?

The serial number on the base of the actuator is more concerning though, nobody should be palming off old stock as brand new unless it is clearly stated on the advert.

I only tried USALS, I'll try the other test.

I'm not defending the seller but there isn't an age limit on stock. And they haven't misled anyone. If someone is trying to palm a different model number off then that's a different story.

Just out of curiosity, what is the serial number on the motor you took delivery of last week ?

It's not quite clear from the image you posted

It's older than TJs, mine doesn't have the satfinder option which his has. I'll have a look when I get home.

But it was new and the box was sealed.

 

[RustySpoons]

Just done a test, if I clear the Limits it does it in USALS and DiSEqC 1.2

These motors are set to 65e-65w out of the factory, if you clear the limits it hits a physical hardware limit and sends it home.
Set the limits back to 65e-65w and it saves them and will not return to home regardless of what receiver you put it on, unless you delete them again.
The manual says this:



I'm happy that mine is performing exactly how it should, if you want something that goes outside of 65e-65w then you need a different motor.

 

[Channel Hopper]

I don't understand what (pretend) USALS software has to do with the problem?
USALS software generates specific Diseqc 1.2 commands (GotoX) for the motor, nothing special about that. The hard limits are not affected by USALS commands or by other diseqc 1.2 commands.

USALS or non-USALS: the weird behaviour of this motor is still unexplained.

Unexplained, though perhaps not isolated. This link appears to have detail that is so close to TJs, #3, #4, and is dated around a year after the motor date of manufacture.

I have a Stab motor working perfectly on my Technomate 5403 M3. Every time I try to run the same Stab motor on my old Technomate 6800 non super, it will go to any orbital position I send it to, then it returns the dish back to 0. If I unplug it and put back my Technomate 5403 M3 it works fine. I am trying to learn what I can do to make my old Technomate receiver work perfect like my newer Technomate receiver.

 

[Channel Hopper]

Allegedly (and this is from a site I don't look at very often), the Technomate receivers should be compatible with the motor.

See attached.

The 6800 is a very capable receiver, (I have a couple of those in the field, still working flawlessly) but from memory predates the Stab rotor, by a year or two.
Perhaps it is not compatible with the command programme required for the motor?

That maybe the case. I think in the summer I will try again but first put limits in the old receiver of 65 degrees to see if that stops it from being sent back to 0.

 

[Channel Hopper]

I just recalled something from around that era, were there not two firmware upgrade processes for the higher spec Technomates ( and Humaxes) owing to hardware differences from the factory ?

My situation with motors is that I used a Jack arm working ku band satellite for around 28 years. The last few years of that time I used analogue receivers to move my dish namely the Nokia 1700 then the Nokia 1800. I have only had my Stab 100 motor for around two years.
It was a pain changing channels on the Technomate 6800 and having to move the dish using the Nokia / jack arm drive. Two years ago I threw a perfect working jack arm and polar mount in the bin so I could at last have everything in sync pressing one button on my Technomate 5403 M3 which works great with the Stab motor. I will add that William1's channel list has breathed great life into my 5403 M3 and it feels like when you get a new receiver in the house.

I would have to.check which motors I have installed on the TM installs, they are all at least nine years old though, some of the larger ones have a v-box converter but the rest are working with a horizon mount ( almost certainly Motecks or Jaegers)

 

[RustySpoons]

From what I understand USALS won't allow you to go past 60 degrees so most people don't notice this happening. The factory have electronically set these to 65 degrees so you won't see it happening when using diseqc 1.2 or manually move the dish with the receiver or satfinder. This only happens if you delete the limits, which includes the ones you set and the factory one. Returning back to 0 must be a failsafe to stop it getting damaged as a last resort, might be there to protect it if the dish is sat right on the limit either end of scale and it's blowing a gale or something too and the wind is banging the dish on its limit. They were never meant to go past 65 degrees so just run them east and west and set both limits to 65 and it should save.

I might try hooking up my old technomate and select Diseq 1.2. I haven't tried that with the Stab, it might have a greater compatibility. I prefer to do my second receiver install experiments in summer when the weather is better in case my dish finishes up wrapped around the pole support and locked there ! Ha !

@TJExcalibur
Can you try setting the limits at 60-65 east and west with a diseqc or USALS command and see if the problem is solved when doing a sweep looking for a signal?

(That would be a diseqc command.
USALS is just the software part in the receiver that calculates from site latitude and longitude and satellite longitude to the needed "Hour Angle", needed for the diseqc GotoX command, as I understand it all.)

I thought about that too, as a "solution".

The weird symptom isn't explained by that, though.
Is it because the limit switch elicits a motor stop command, a reset command, or something else? By the receiver, or by the motor itself?
And were the sent motor commands really identical?
You'd need a diseqc command reader, to test this, at the receiver/satellite-finder end.
Was no LNB attached to the motor, while testing? That could have had an effect, too.
Would it be possible to think of a testing setup (modifying the motor), where the symptom could switch to the other limitswitch? Which would make it clear that is really is a motor problem, not a receiver problem?

I wish the paypall complaint committee lots of wisdom.....

Does it with and without LNB, motor logic does it not the receiver. As long as the motor has 12/18v it carries on going back.

As I mentioned they really should have hard coded limits as well, if no one does a delete this won't happen. So the way to put it back to factory is set them 65/65.
