A main card runs all the functions of the
machine, traction, brush base, vacuum
and water. The main card receive as in-
put, all the information from the control
card, the safety micro and all the elec-
tronic devices of the machine. These sig-
nals are translated from the main card
to run correctly the scrubber dryer and
to prevent any safety problem to the op-
erator. The dash board can be used
also as a programmer console to mod-
ify the parameter of all the machine’s
functions (traction, vacuum and wash-
ing) and, also, to check the consumption
of all the motors and batteries.
