34 - Scrub System, Disc
Functional Description
The disc brush system can be started by the
operator.
The disc brush turn counter-clockwise.
The rotating brush system cleans the surface of the
oor. The main component of the brush system is
the deck where the brush or the pad holder with
pad suitable for the type of surface to be cleaned is
installed.
The brush deck is installed on a two lever frame with
pedal lifting for connection to the frame integrated
with the brush motor is coupled.
The pedal lever lifts and lowers the deck. The
operating and washing pressure depends on the
weight of the deck.
Brush rotation occurs only when the brush motor
(M1) is driven by the Main machine controller
(EB1) following activation of the operator’s presence
sensors (S1, S2).
The brush system uses the solution to wash the oor.
In case of brush motor overload, a safety system
stops the brush to prevent continuous overload.
The overload is detected by monitoring the current
ow on the brush motor. If the motor current reaches
the value stored in the parameter “VS1” and the
overload persists, the brush motor will stop following
a delay which varies on the basis of the extent of the
overload.
To start scrubbing again after a brush stop due to
overload, turn the machine off. Then restart the
machine by inserting the ignition key.
To work properly, the brush motor (M1) needs the
following:
• Brush function on.
• operator’s presence sensors on.
• Battery level not in critical condition with
ashing segments.
Brush Engage and Release System
To easily and successfully engage and disengage the
brush from the deck hub, there is a Main machine
controller control system which adjusts the brush
motor speed and stop.
Brush Engagement
When the machine is turned on (main button LED
on), if the vacuum button
and the main
button
is pressed simultaneously, the brush
motor is powered at the reduced voltage of 8V
for 3 seconds in order to facilitate the brush hub
engagement.
Brush Release
When the machine is turned off (main button LED
off), if the vacuum button
and the main
button
is pressed simultaneously, the brush
motor is powered for 3 seconds, then it will be
stopped allowing under inertia the brush release
from the hub.
