Scrub System, Cylindrical
Functional Description
The cylindrical brush system can be started by the operator
The cylindrical brushes turn in opposite directions towards the centre of the deck
The rotating brush system cleans the surface of the floor. The deck, where brushes suitable for cleaning the
particular type of floor are installed, is the main part of the brush system.
The brush deck is mounted on a “magic deck” pantograph system with an electrical actuator The “magic deck”
system also traverses the deck to the side if it collides with an obstacle
The electrical actuator, with limit microswitches, lifts and lowers the deck. The operating and washing pres
-
sure depends on the weight of the deck. The cylindrical brush system does not have extra pressure function.
The brushes rotate when the brush motors are activated by the function electronic board when the pedal is
pressed
The cylindrical brushes are driven by a belt and pulley transmission system
The brush system uses the solution to wash the floor.
The 2 side skirts direct the washing water towards the rear squeegee
There is also a removable box on the deck where the debris cleaned by the brushes collects.
In case of brush motor overload, a safety system stops the brushes after about one minute of continuous over
-
load. The overload is shown by the three battery warning leds flashing simultaneously.
The overload is detected monitoring the sum of current flow on the motors. The current is measured by a volt
-
age drop verification across the brush system fuse (F1). If the voltage drop become over the value stored in the
“VS2” parameter (default = 70 mV), the 3 battery leds start flashing simultaneously and if the overload persist,
after a variable delay depending on the overload amount, the motors will stop.
To start scrubbing again after a brush stop due to an overload, stop the machine by turning the ignition key to
“0” Turn on the machine by turning the ignition key to “I”
In summary, the brush motor running needs the following conditions/inputs:
•
Seat microswitch closed
•
Brushes function enabled
•
Drive pedal pressed
•
Battery level not in red light blinking condition
