The control electronics covers all control and monitoring functions in the machine
except for drive control.
Operation of drive controller is independent from the other electronics and only the
release signal and the signal for speed reduction are transmitted via control
electronics to drive controller. Beyond that, a signal is transmitted from drive controller
to control electronics for forward and reverse ride.
Upon occurrence of a defect on the drive controller, an error code is not output since
this controller has its own diagnostic indicator (see chapter 10).
The buttons for scrubbing, suction, scrubbing and suction and the green Hako button
for combined cleaning may be switched arbitrarily such that the selected function is
activated. Pre-sweeper/side broom and /or side brush function can be activated or de-
activated disregarding of the selected cleaning mode, if present in the machine.
The remaining functional buttons (water, brush ground pressure) allow activating or
de-activating the related functions in addition to the cleaning procedure without effect
on the running function.
