Starting the new season, I’m doing a lot of improvements in my system. Now I’m rebuilding the dish controller. The idea is get more mechanical precision and reduce the backslash. I hope improve the security too.<\/p>\n

The selection of the speed and motion of the linear actuators was controlled by a ADAM 4068 relay module. It has been changed by a ADAM 4052 Digital input\/output module, to reduce the reaction time and reduce the backslash. Now the ADAM 4068 relay module is used as watchdog to stop all if the comunication with the linux server is lost. I added a Emergency stop push button to the controller box.<\/p>\n

Finally I added a RFI EMI power line filter and some ferrite core filters to reduce the RFI noise that was generating the controllner in HF.<\/p>\n","protected":false},"excerpt":{"rendered":"
