THEORY OF OPERATION

Limit switches

There are two types of limit switches which are
found in various locations on the machine: drive
speed limit switches and a drive enable limit
switch. The function of a drive speed limit switch is
to limit the raised or extended drive speed to 0.6
miles per hour (1 km/h) when the primary boom is
raised more than 2 feet (0.6 m) OR when the
primary boom is extended more than
18 inches (45.7 cm). The function of the drive
enable limit switch is to limit the ability of the
machine to drive when the boom is rotated beyond
the non-steer wheels.

Machine Controls

The Genie S-60 and Genie S-65 machines are
equipped with operational controls which are found
in two locations: the ground controls, located on
the tank side of the machine, and the platform
controls, located in the platform. All lift and drive
functions are available at the platform controls.
Only boom functions are available at the ground
controls.
Ground controls are activated by holding the
function enable toggle switch to either side, then
moving a boom function toggle switch in the
direction indicated on the control panel decal.
This will determine which boom function will
operate and its direction of travel.
Platform controls use toggle switches and boom
function controllers (joysticks) to operate the boom
functions. The drive controller (joystick) regulates
the drive pump displacement through the EDC in
direct relation to the drive controller position. A
thumb rocker switch on the top of the drive
controller is used for steering.
