Cleaning programmes (FPV)

The cleaning programmes are used to specify the behaviour of the water supply to the
brushes, the brush motors in relation to the position of the driving direction switch and
the drive potentiometer (forwards, neutral, reverse) as well as the squeegee.
A GND signal via XS11 is set to the input of the driving direction switch at A02.X6:4 via
the drive potentiometer switch in B03. When driving direction 'forwards' is selected on
the control panel, this signal is set from A02.X6:2 to inputs A01.X10:12 and A04.A1 via
potential distributor XS04. When driving direction 'reverse' has been selected, the
signal is set from A02.X6:3 to potential distributor XS05 and thus to inputs A01.X10:13
and A04.A2. If no GND signal is present at A01.X10:12 or 13, the cleaning units are
not activated. If this signal is missing at A04.A1 or A2, the machine cannot be driven.
The behaviour of the cleaning functions is described in Table 5.1.
In order to select a cleaning programme, the programming level must be accessed as
described in Chapter 2.2.4. The available cleaning programmes are listed in Table 5.2.
Press tip switch 3 for at least 3 seconds to save the programme change.
Subsequently, disconnect the diagnostics plug from A1.
