Tm2600 motor not getting power after driving dish to 30w

[blackburnman04]

Hi all,

I am currently using a Skybox V8S with a motorised setup (TD110 dish and TM2600 motor). I had noticed some slight signal decrease over time on most satellites, and yesterday I went to do a channel scan on 30w. The dish started to move as usual, but when it reached 30w it made a horrible sound, which led me to believe that the satellite dish had fell off the bracket so I went out to inspect. The dish was still attached to the bracket and motor securely but it seems that the dish is at a position that is further west than 30w.

I tried to go to x to get the dish back to starting position,but there is no power no being received on my tm2600 and no green light being dispalyed either. I also tried to press the manual east/west button but nothing. The motor seems dead. I also tried to drive the motor using a friends dm800hd but there is still no sign of life from the motor.

My question is, is it possible that if the dish (TD110) is driven beyond 30w that it could cause the motor to break in some way or dislodge something inside the motor causing it to no longer power? I don't think the cabling is an issue as the motor was moving without issue until i tried to scan in 30w.

Many thanks for reading and to anyone who views this post or provides solutions

Ooh dear that doesnt sound good!

My first thought from your description was stripped gears and its swung round till its hit its end stop. One way or another you will have to dismantle the dish / motor assembly to see the extent of the damage inside the motor casing.

Sounds like either the gear has been stripped (no mean feat, TM2600 has all-metal drive) or shattered the drive mechanism, either way a new motor is probably in order.

Thanks for the advice everyone. I will buy a new motor and ensure that it does not go past 30w in the future.

Agree with other replies... Possibly whatever mechanical damage transpired also took out the electronics. 30w is not really am extreme, so odd for it to fail like that.

 

[blackburnman04]

Is it possible that it could have been that the dish is too heavy for the motor and that is what might have caused this, when driven towards 30w?

If this is the case, is there any other motors that would be able to support the weight of the dish, or is the tm2600 as good as it gets for Diseqc motors?

I'm using a 1.2M Laminas fibreglass dish on a Clark Tech motor. It's been up over 5 years now and has survived all the storms this area can throw at it. The dish is pretty light though...

OUCH! That does not sound very good at all! Motor replacement time.

 

[Captain Jack]

TD110 dishes are not the lightest but should be easily handled by DiSEqC motors - especially metal geared ones, such as the TM2600. I had a 1.2m Gibertini dish, which has very heavy mounting brackets, on an original Moteck SG2100 motor with nylon gears and that was up for years without issues (in a sheltered location), driving the dish from 30W to 53E.

How long has it been up?

Will be interesting to see what the issue/cause is.

Is definitely be interested to find out what's happened inside the casing!

It has been up for around 5 years now. I will post some photos of the inside of the casing when I get the new motor

 

[Captain Jack]

5 years... hmm... Not a short amount of time but I would expect them to last longer than that.

 

[blackburnman04]

Not sure if it might be a factor but my dish is mounted in quite an open area, not coastal but the Northern Irish wind does seem to hit it quite forcefully.

 

[Captain Jack]

More than likely. Dishes act as sails in the wind and put quite a bit of load on the motor.

Just for info, the Clark Tech looks like it's now a 'Powertech'...this is the place in Germany I bought mine from...

Well that motor is rated to move a 1.2 meter dish all day long without problems.

So what happened? Is 30W set as your furthest East/West satellite with the hard stops? (Mechanical stops)

Or does it have room to move beyond that satellite? (with no structures in the way)

Yes wind loading is a factor in this.

A 1.2 meter dish with a 50 mph wind (or higher) against it would have a substantial force pushing on it, this can overload the motor.

To calculate this you need the surface area of the dish in square feet. (don't remember how to do it in square meters)

A 1.2 meter dish would have a surface area of 12.566 square feet.

Then you need to calculate the total force of the wind against it, this is done by squaring the wind velocity and multiplying by .00256, (50 x 50 x .00256) this give us 6.4 pounds per square foot of extra force against the dish. (if the dish is facing the wind head on)

So take the 6.4 and multiply it by the square footage to get an additional push of 80.4 pounds against the dish. (again if the dish is facing the wind head on)


This can severely overload the motor to a point where the clutches give way or something else goes FUBAR.

If its in an exposed location then you will just have to accept that the motors will fail after a few years usage or after a decent gale. Strong winds put a tremendous turning force on big dishes, far in excess of what any motors are designed to stand. If you had installed one with nylon / plastic gears you would have found it inoperable due to stripped gears long ago.

The dish should realistically be able to move further than 30w, as there is no structures in the way, but I have never needed to go past 30w, so I have never tried.

Thanks for the calculation . It is amazing how much pressure can be put on the dish due to wind.

Thank you for the responses everyone.
