STAB HH120 Diseqc motor connection through a Diseqc switch

[el bandido]

What is the make/model of the lnb on the motorized dish?

Have you checked for proper operation of the motorized dish by using a barrel connector to temporarily eliminate the switch? In other words, does the motorized system work correctly without the switch installed?

The LNB is a GEOSATpro UL2PLL UNIVERSAL Phase Lock Loop Linear Ku LNBF. I will check that. I will test the system without the switch first. That is what I should have done from the beginning. I will test it and let you know about the results.

Hello,

Just for the records. I finally got the correct setup. This switch is a combination of committed and uncommitted switches. I found a recommendation from other switch manufacturer and "adapted" it to the DiseqC command sequence of mine. See attached pictures.

Excellent Work! Good to see that you found a solution! Hopefully your work will benefit someone else.

I hope so!!!

And I hope you put the motor before the switch or you may run into problems further down the road.

I have ran switches in front of Ku motors before and didn't have any problems with it. I also put a milliamp meter inline to see how much current the motor pulled when running. The motor running does not draw much current when running, something like 50-100 milliamps. But you may see a brief spike around 200-350 milliamps when the motor starts a 1.2 meter dish on the lowest end of the satellite arc. The bottom line is these types of motors just don't draw as much current as some think they do.

And I also agree that the motor should not have a switch between it and the receiver. But this is a hobby and things are not always done the way they are supposed to be.

Wondering. During motor activation does the lnbf power shut off?

Does the lnb power shut off when the actuator motor is moving on your c band dish? This stuff is setup the same and does not care about the band. So the answer is No.

Consumer lnb(f)s do not need much power to operate. Commercial DRO lnb types usually use less power than Commercial PLL types. Some commercial lnbs(2) may require more power than the receiver is capable of producing. Most fta satellite ku dishes will have a cheap dro or cheap homeowner type pll lnb. So no need to worry with turning lnb power off for motor moves. Turning lnb power off would just be something else that can go wrong in the system.
