23Service Manual – SC6000 04 - Control System
Control Panel
The control panel (display) is an integral component with
the Main Machine Controller circuit board. The control
panel contains an LCD display, SmartKey reader for the
keyswitch, and a series of membrane switches for operator
control.
SmartKey Reader (A): The key reader provides a serial
connection between the SmartKey and the main machine
controller. The controller checks the serial number of the
key to determine if it is authorized to enable the machine’s
operation.
Different keys (operator-blue versus supervisor-yellow) have
different levels of access to the control system. Operator
keys can be authorized/de-authorized for the machine,
so that each operator may have his or her own uniquely
identied key.
Power Switch (B): When a key is in the key reader,
pressing the power button will boot up the controller and
turn the machine on. Pressing and holding the button for at
least 1/2 second will turn the machine off.
Display (C): The LCD display provides feedback to the operator
with various text messages and graphic icons. The main screen
shows scrub pressure, solution ow, detergent ow, speed, machine
hours, battery charge level, solution tank level, and any fault codes.
The display will change as necessary to convey the appropriate
information.
Information (D) and Menu Navigation (E): Pressing the information switch enters or exits the system
menus. The navigation switches provide navigation and entry for the menus, and will be discussed in greater
detail in “Programming Menu Outline” on page 27.
One-Touch Scrub (F): When the One-Touch Scrub is selected, the brushes and squeegee are lowered to the
oor, and the solution solenoid is briey activated to pre-wet the brushes. The scrub, solution, vacuum and
detergent (EcoFlex models) systems are all enabled and will start when the Drive Pedal is activated.
Solution Switch (G): The solution switch enables or disables the solution solenoid. However, the solution
solenoid isn’t energized unless the scrub system is engaged and the machine is in motion.
Vacuum Switch (H): The vacuum switch turns the vacuum on and off, and automatically lowers or raises
the squeegee. Because a hand operated vacuum wand is available as an option, the vacuum will operate even
when the operator is not in the seat and the seat switch is closed.
Speed Limit Switch (I): The speed limit switch sets the maximum speed of the machine to whatever the
current speed is in scrub mode to reduce driver fatigue. Allows full pedal deection at the set speed.
Detergent Switch (J): The detergent switch enables or disables the optional detergent pumps. However,
the detergent pumps aren’t energized unless the solution system is also active, and the machine is in motion.
Headlight Switch (K): The headlight switch controls the optional headlights on the front of the machine.
Brush Install Switch (L): The brush install switch lowers the deck and spins the brush motors briey to
aid in the installation of the brushes.
Dust Guard Switch (M): The side sweep switch controls the optional side sweep broom and optional dust
control pump and solenoid. However, the side sweep system won’t be active unless the broom is lowered
(proximity sensor closed) and the scrub system is active.
