B.6. Operational limitation<br />
Elevation Limit<br />
OPERATIONAL LIMITATION<br />
There are two pre-limit switches and two final limit switches on the elevation housing. When the<br />
limit switch cam presses on one of the pre-limit switch’s plunger tip, the pre-limit switch sends a<br />
logic signal to the DCU. The DCU prevents the motor from turning forward, but does not<br />
prevent it from turning in the opposite direction. Once the limit switch cam presses on one of the<br />
final limit switch’s plunger tip, the final limit switch sends a logic signal to the DCU, which<br />
inhibits the elevation drive power amplifier output, to further stop the motor. Once the antenna<br />
elevation exceeds the up or down final limit, the two mechanical shock absorbing stops, mounted<br />
on the two sides of the elevation housing, gradually absorb the antenna motion kinetic energy to<br />
ensure the safety of the pedestal system.<br />
Elevation Limit Angles<br />
The elevation limit settings and tolerances (in degrees) are factory set and are as follows:<br />
Pre-limit (+): 90.2º±0.2º Pre-limit (-): -1.2º±0.2º<br />
Final limit (+): 94.0º±0.2º Final limit (-): -2.0º±0.2º<br />
Mechanical stop (+): 95.0º Mechanical stop (-): -3.0º<br />
