Operation
Step Step Step
Move the antenna in azimuth to obtain a null, then move ± in elevation to obtain a large peak signal. If not, move the antenna in the opposite azimuth direction through the peak and again move ± in elevation to obtain a large peak signal. If a larger peak is not found, you were on the main lobe

and minus direction from the local control/motor drive controller at least once every three months during antenna down time. Check the mechanical limit switches provided at the end points stop the antenna and feed movement, and limit travel to prevent struc- tural interference and damage. Check the mechanical limit switches for corrosion and water entry and the arm on each feed limit switch for free movement without binding. Be certain both feed rotation limit switch arms are not distorted and ride centrally on the actuating cam to open their corresponding limit switch

Drive System Voltage and Current Checks Step Step
Step
Turn the AZIMUTH EAST/WEST switch to either position and while the antenna is rotat- ing, carefully use a clamp on ammeter in accordance with the ammeter manufacturer’s instructions to take current readings off each of the three conductors phases connect- ed to the load side of the azimuth drive motor circuit breaker. Record the current draw in the equipment log and compare the readings to the reference values entered in the installation/acceptance check off. If the readings differ by more than five percent, refer to appropriate troubleshooting information and perform applicable corrective action. Then take voltage readings off each of the three conductors; the readings should agree with each other—withintwo percent
