ELECTRICAL SYSTEM
FUNCTIONAL OVERVIEW OF MAIN CONTROL BOARD
The primary function of the main control board A1 is to position the scrubbing brush(s) with respect to the
fl
oor surface using a lift actuator motor to maintain the
correct brush pressure and current draw of the brush motor(s). When the scrub ON switch is depressed this will lower the scrub deck to the operating position and by
activating the drive paddle start the brush motors. The controller is continuously monitoring the current to the brush motors and when it senses a current draw out of
the desired range it automatically raises or lowers the brush deck by turning on the brush actuator motor. This process is repeated until the brush motor is shut off.
The controller also manages the other supportive systems such as the solution on/off, and vacuum motor. Note: See the Know Your Machine system in this manual
for a complete explanation of the machine’s operation.
The secondary function of the main control is to detect any system failures and display an error code on the display LED panel or store it in the main control board’s
recall memory mode. The error code(s) are used to help the serviceperson determine the fault and to quickly guide in repairing a speci
fi
c 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 speci
fi
c
machine functions. See the
Main Control Board Special Program Options
section in this manual for further information.
TROUBLESHOOTING GUIDE
Any error codes detected by main control board will be displayed on the LED display panel as they occur. If more than one-error exists the display will sequence
through the error codes at one-second intervals. The error display will show on the display LED panel as a mechanical wrench symbol followed by a two-digit
code. EX: 03 would be a drive system fault. When troubleshooting any “Fault Description” noted with a double asterisk (**) follow the instructions for entering
the SERVICE TEST MODE in the control boards special programs. See the
Main Control Board Special Program Options
section in this manual.
