3.4 CONTROLS AND INDICATORS
Ground Control Station
DO NOT OPERATE FROM GROUND CONTROL STATION WITH PERSONNEL IN
THE PLATFORM EXCEPT IN AN EMERGENCY.
PERFORM AS MANY PRE-OPERATIONAL CHECKS AND INSPECTIONS FROM
THE GROUND CONTROL STATION AS POSSIBLE.
NOTE: When the machine is shut down for overnight parking or
battery charging, the emergency stop and power select
switches must be positioned to off to prevent draining the
batteries.
1. Platform/Ground Control Switch
A three position, key-operated power select switch
supplies operating power to the platform or ground
controls, as selected. When positioned to platform, the
switch provides power to the emergency stop switch
at the platform controls. When positioned to ground,
the switch provides power to the ground control. The
ground control emergency stop switch provides
power to the key switch. With the power select switch
in the center off position, power is shut off to both
platform and ground controls.
2. Platform Lift/Lower Switch - A three position, momen-
tary contact Lift control switch provides raising and
lowering of the platform when positioned to up or
down.
3. Emergency Stop Switch - A two-position, red, mush-
room-shaped emergency stop switch, when posi-
tioned to ON with the power selector switch
positioned to ground, furnishes operating power to
the ground control station. In addition, the switch can
be used to turn off power to the function controls in
the event of an emergency. Power is turned on by pull-
ing the switch out (on), and is turned off by depressing
switch.
