SuperMount 1224 H-H Motor

bauderline

Folks,

Does anyone have any experience of setting the mechanical limits on one of these yokes ? I think mine is limited to 35/40 on the east west limits and I would like to set it to 60 at either end.

I have googled like a good thing but can find no information online and the prospect of searching the attic for the manual does not appeal to me in this weather so any help is appreciated !

Best Regards, Peter.

Take off the cover. Your should be able to to see a circular saw-toothed 2 piece cam which is spring-loaded. This cam moves in sync with the mount. The cam is split into two halves, upper and lower. There is a protrudence on each of the cams which hits the limit switches and activates them.


Pull the first cam up and rotate away from the switch to set one limit (can't recall east or west). Pull both cams up and rotate to set the other limit. You might need to readjust the upper one again to get the settings just right.

Some HH motors have fixed mechanical limits due to a limited arc of cogwheel on arm. These are usually max +/- 46 degrees which won't allow them to work on Midwest Ireland to get 42E.

Thats true...

But the Jaegar Supermount 1224 is a true horizon to horizon 36V motor capable of 70W to 70E not that many people are able to avail of it !

+/- 70 deg is a more than realistic limit. Beyond this, unless you are on a 500m mountain top all you will receive is thermal noise no matter how big the dish.

The 36V overcomes the feeble speed of a LNB feed powered Diseqc motor or allows larger (e.g. 3.7m) dish compared with 1.1m limit of most Diseqc motor. Motek have an adaptor to allow a Diseq Receiver (or indeed use a separate remote control if no motor support like Digibox) to control 36V jacks/ motors

I have the motek unit as well, the intention is to drive the dish using my dreambox 7020 (a really nice bit of kit!), however it is current being driven by the Technomate 5500 dapci I have downstairs, the motek/dreambox are on a long todo list.

First on the list is proper alignment of the dish. The 36V motor can handle the wind load factor of a 1.2m dish on a windy hill in Cavan without issue. My concrete foundations however could not...

As the pole is not dead vertical anymore I cannot track the belt. Once the warmer weather arrives I am going to tackle it with a kango and a considerable amount of concrete !
