DigiPower SG2100A Diseqc Motor - Hardware limits

[Burnham Beech]

I recently obtained a used DigiPower SG2100A Diseqc Motor.

Visually it is identical to various other diseqc motors - eg Moteck SG2100A, Jaeger SG2100A, Technomate TM-2600 & Alsat Dark motor. There are probably similar others as well.

I downloaded a user manual after a net search for SG2100 (generic - did not say DigiPower - did not say SG2100A). It says there are hardware limit stops which can be set when the stub arm is removed. These do not exist on my motor.

Does anyone know if these hardware limits were removed when they went from SG2100 to SG2100A (or the equivalent "upgrade" for the other brand names).

This confused me too when I first acquired such a motor: With the stub removed, you then have to lift the leading edge of the metallised foil label in order to expose the set screws for the hardware limits.

As I recall, it's not immediately obvious that you have to do that.

Just been up to the cave to look at my spare motor, a Fortec Turner, which is also a Moteck clone and it has access to the screws in the way I described.

That said, I very much doubt most people actually bother to adjust them from their preset value of, I think, +/- 65 deg.

I have looked at my motor again, but there is nothing underneath the stub arm.

I want to set hardware limits as an extra safety measure as it will swing over some tiles on a low roof. I can't see beyond 35°w so I might as well limit the swing (were it possible)

 

[Lazarus]

Well, that seems odd.

I'm sure you know you can set Software limits in most (All ?) proper Receivers.

?

Yes, that's the same diagram and information I have in the manual I managed to download from a net search.

The problem is that my motor does not have the limit sliders as shown in the diagram above.

I thought there might be something inside the housing that I could access to set hardware limits, but I don't was to take the housing apart unless I'm sure that the is something there to set limits.

As to setting software limits.

Yes, very easy to do, but I never trust anything software related when there is a risk of damage to a roof or a dish.

I think I have a motor in parts in workshop, I will have a look and post some pictures of any limit switches inside if there is any.

 

[blademedia]

This should be the same motor unsure where limit switch is, maybe @Trust1 will know

 

[Lazarus]

Well I can see from the most recent photo of Blademedia's spare Motor that there is indeed the fundamental difference between some Moteck clones that led to the original question above .....


..... The metallised foil label on variants (like mine) that do have adjustable hardware limits is much larger and has a tongue/flap which extends as far as the front under-edge of the casing. Clearly it does so in order to act as a cover for the set-screw access.

The motor above only has a minimal label and would seem to be the give-away that indicates a variant without the adjustment facility.

As they say in these parts, I'll go to the foot of our stairs.

 

[Lazarus]

I've managed to find the right sized Allen Key and taken the stub off my spare and will shortly post up pics showing the label in situ and then peeled back to reveal the adjusters.

Just got to figure out how the camera works on this Tablet!

Here tha goes

That's the best I can do.

At the little circuitboard in the yellow gear are 2 micro switches , one active at the east sector and opens at zero , the other one is the limit switch .
In this motor are only fixed end positions .

Es un clon del SG2100, tengo 2 originales.
Aparte de los límites fisicos, tienes más diferencias (me dieron un clon similar).
El original tiene un pulsador para mover, izquierda - derecha.
El clon tiene 2 pulsadores, uno para cada lado.
La goma / pulsador donde esta el led y tiene el reset, en el clon no tenemos reset, se realiza cuando apagas y enciendes el motor.

Si haces pruebas y lo cambias de sintonizador, cuidado, que toma la referencia donde este como posicion cero.

Como el original (con limites hardware/tornillos) tienes de FTE Maximal DIMO 120 y Dimo 120+.
Tambien de Satellite Rover Digiready H-H Motor SM-100 (con 2 pulsadores).

It is a clone of SG2100, I have 2 originals.
Apart from the physical limits, you have more differences (I was given a similar clone).
The original has a push button to move, left - right.
The clone has 2 buttons, one for each side.
The rubber / pushbutton where the LED is and has the reset, in the clone we do not have reset, is done when you turn off and start the engine.

If you test and change tuner, be careful, it takes the reference where it is as zero position.

Like the original (with hardware / screw limits) you have FTE Maximal DIMO 120 and Dimo 120+.
Also from Satellite Rover Digiready H-H Motor SM-100 (with 2 pushbuttons).

Had a very quick look at my Superior Dark motor this afternoon - no sticky label on the lower flat side and so I think I would have to dismount it and remove the complete metal cover to see what is underneath. Don't want/need to do that because the dish can't hit anything (except the thin branches of a small tree right next to it), but would be interested finding out what is underneath if anyone does take the cover off.

Great posts everyone, with some good information. Thanks to all.
