Control Panel
Main Controller
The Main controller
(A1)
, which includes the control board
and the display, is the primary electronic control for the
machine and its functions (except drive control). The control
board is the basic input/output device and contains a micro-
contoller chip to regulate function. The controller receives and
interprets user inputs, sensor inputs, and even some motor
amperage readings, and controls device output for the user
display, solenoid operation, and motor control. Most low and
medium power outputs are controlled with power MOSFET
transistors, with some moderately high power devices
controlled with micro-relays, and very high power devices
(vacuum and brush motors) controlled with external motor
contactors.
Another function of the main controller is to detect any system failures and display an error code on the display
panel or store it in the main control board’s memory. The error code(s) are used to help the service person determine
the fault and to quickly guide in repairing a specific system malfunction. Note: See the Troubleshooting Guide for
further information. An additional special feature of the main control board is to change program settings for a set of
specific machine functions. See the
Main Control Board Programing
section in this chapter for further information.
Main Control Board Programming
The Main controller is programmable for machine specific functions and parameters. This is a required task when
replacing the controller with a new controller. The table below and following sections describe the parameters to be
programmed.
