Pressure switch for minimum air pressure (8)
The pressure switch for minimum air pressure (8)
is used to continuously monitor the air pressure
set on the pressure control valve. As soon as the
air pressure set on the pressure control valve falls
below the minimum value set on the pressure
switch, the pressure switch issues an electrical
signal that can be evaluated as a malfunction
notification by the machine control unit or the
compact unit's control unit. The minimum air
pressure must be monitored, as insufficient com-
pressed air supply carries a risk of underlubricating
the lubrication point because the lubricant in the
lubrication point lines is no longer reliably trans-
ported to the lubrication point.
