Tower Path Control System
The Tower Path Control System uses the envelope control sensors
to enhance the control of the tower boom for increased user effi-
ciency and is used as an integral part of the envelope control sys-
tem.
Both the ground and platform control panels use one function
switch to control the tower. User commands for tower lift up or
tower lift down causes the control system to automatically intro-
duce the correct combination of tower telescope and tower lift
for the tower boom to follow a pre-described path or trajectory of
the tower nose.
