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 antenna and feed movement, and limit travel to prevent structural 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 cer- tain both feed rotation limit switch arms are not distorted and ride centrally on the actu- ating cam to open their corresponding limit switch
Preventive Maintenance
Drive System Voltage and Current Checks Step Step Step
Preventive Maintenance
tain all electrical grounding connections including cross-axis grounding straps are intact and secure, not corroded or broken. Thoroughly clean any noticeable corroded portions of grounding cables, unplated portion of universal terminals and corresponding mounting surfaces using a wire brush. Replace rather than tighten any loose A-325 structural hardware. The hardware distorts at initial installation and once loosened will not maintain the required high strength friction connection. All other assembly and instal- lation hardware should be tightened to its original torqued condition. When installing new structural hardware, do not use a wrench with a lever arm longer than two feet
Step Step Step Step Step Step
Preventive Maintenance
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-within two percent. Turn the AZIMUTH switch to OFF
Lubrication
Preservation of Component Parts Aluminum Parts Galvanized Surfaces
Preventive Maintenance
Remove all loose paint and corrosion by scraping, wire brushing, or using steel wool. If using steel wool near the feed window, make sure that none remains on the feed horn window. Edges of existing paint can be blended with the metal surface by using a fine grit sandpaper. Wipe the surface to be painted with a soft rag dampened in trichlorethyl- ene, lacquer thinner or equal. Be certain to remove all loose paint, corrosion, imbedded dirt, grease, and oil deposits or the paint will not adhere to the surface. Lacquer thinner will dissolve paint if applied heavily and rubbed vigorously. The reflector may be washed with plain water if necessary. Do not use bleach, soap solutions, or kerosene as it is dif- ficult to remove the residue. Allow the cleaned surface to dry thoroughly before priming
