Platform Controls
The platform controls contains two printed circuit
boards:
The LED circuit board is mounted to the underside
of the control box lid which contains the LEDs. The
LED circuit board sends the input from the operator
to the platform controls circuit board (PCON). The
circuit board (PCON) sends the data to the
turntable control box (TCON) for processing.
The platform controls ECM circuit board
communicates with the turntable controls. The
joystick controllers at the platform controls utilize
Hall Effect technology and require no adjustment.
The operating parameters of the joysticks are
stored in memory at the turntable controls. If a
joystick controller error occurs or if a joystick is
replaced, it will need to be calibrated before that
particular machine function will operate. Refer to
Repair Procedure,
How to Calibrate a Joystick
Controller .
Each joystick controller should operate smoothly
and provide proportional speed control over its
entire range of motion.
