ALC-600 Control Module
Platform Controls
The platform control box contains the ALC-600
platform Control Module. The platform Control
Module receives all signals from the platform
switches, joysticks and foot switch, and provides
operator feedback through an Indicator Module.
The joystick controllers at the platform controls
utilize Hall Effect technology and require no
calibration. Automatic calibration of center voltage
occurs on power up if the signal value is in the valid
range. Each joystick controller should operate
smoothly and provide proportional speed control
over its entire range of motion. The remaining
boom functions operate by on/off toggle switches.
