Verify Az And El Hardware Limits; Figure 14: Verify Jog Direction Screen - Andrew OMACS3000 User Manual

11-APR-06
The operator must select the buttons to move in each of the directions allowed by the screen. If the pol drive
is not installed, only East, West, Up and Down jog directions will be displayed. The observer must let the
operator know if the direction commanded by the operator is the same that the antenna actually moves. If
any direction movement is incorrect, initialization must stop and the antenna wiring must be corrected before
restarting the initialization. If the direction selected moves as indicated (for example, Az West increments
the Az displayed at the top), the operator should select the appropriate check box to set the check mark.
Once all directions have been verified, the operator should enter Next to go to the next step.

Verify Az and El Hardware Limits

This step in the Initialization Wizard also requires an antenna observer who is in contact with the antenna
controller operator. The observer is needed to request emergency stop from the operator if any wires or wire
harnesses become entangled as the antenna moves or the antenna moves beyond its physical limits.
The observer must be in position to stop the hardware
from moving into obstructions, twisting wires, or moving
beyond physical limits.
The operator moves in each of the directions allowed by the screen. If the pol drive is installed, it will be
checked in later screens. The operator will jog each axis one at a time until that axis reaches the physical
limit. The operator will know that the limit is reached when that direction checkbox is checked. The operator
should also notice that the resolver counts (as displayed by the position status line) will discontinue counting
