Machine description
3.4 Compressed air regulation unit
By default, the air regulators and pressure
gauges for the air inlet pressure of the pro-
portioning pump and the flushing pump are
installed in the compressed air regulation
unit (see Fig. 7). Depending on the configu-
ration of the machine, further air regulators
and pressure gauges can be added for
optional extensions and accessories.
The compressed air regulators and pres-
sure gauges in the compressed air control
unit are marked by symbols:
Proportioning pump
Flushing pump

The functional principle of all compressed air regulators
on the machine is the same:
➤
In order to increase the pressure, turn them clock-
wise,
➤
in order to decrease the pressure, turn them anti-
clockwise.
3.5 Pressure and metering monitoring
The 2 buttons and the selector switch on the control cabinet beside the com-
pressed air regulation unit as well as the contact pressure gauge belong to the
pressure and metering monitoring.
