The new controller for the rotator

New Controller (Driver) the rotator is finished. Compared with the original electromechanical controller from the manufacturer has the advantage of accuracy natočení see antenna, Silent running, size and visibility at night. Measurement natočení antenna – azimuth – is realized with a circular display 36 LED diodes, which gives foursome integrated circuit LM3914. Sensor is a potentiometer desaťotáčkový, which is mechanically connected with the transfer of the rotator.

Change is also in how rotator. Of the original controller is used only a transformer and capacitor. Clamant electromechanical switch and indicator natočení was replaced by a simple switch. After one or pushing on the other hand, triggered the contacts and the rotator will rotate.

Inside are placed two more printed circuit boards – single source of LM317 and two desaťotáčkové calibration potentiometers for precise setting between 0 ° and 360 °.

Because of a simple and rapid engagement are not used terminals. Towardontrolér rotator is connected with 5-wire cable culminating DIN connectors.
