8.5.2 Pressurelimiting valveswith microswitch
The maximum operating pressure in the lubrication system can be electronically monitored by a micro switch which is
attachedat thepressure limitingvalve.
The micro switch is operated when the pressure in the lubrication system exceeds the value set at the pressure limiting
valve (see fig. 30). The emitted signal of the micro switch can be used customer specifically, e.g. for switching off the
device, or it is evaluated by the integrated control unit PICO-tronic (see chapter 9.2.8 „Function System pressure
monitoring“).
