Overview
During a bi-annual maintenance work which was carried out on the 32m dish antenna at GRAO Kuntunse, the task was to investigate the following operational condition:
- Azimuth Wheel Grounding Brush
- Antenna Limit Switches
- Elevation Stow- Pin switch
The Azimuth wheel grounding investigations had to do with checking on the wearing status of the brushes so as to ensure that they meet the standard width for operation.
On the antenna limit switches, a multimeter was used to measure the switching status of the switch so they would be able to open and close, for controlling the operation condition of the antenna.
The Elevation stow pin is electrically driven by a motor to a mechanically bar which is coupled to the antenna through a hole which keeps the antenna at a 90 degrees position during maintenance work and also in an event of heavy storm which could endanger the antenna to rip off.
