9.3.3. Micro switch at pressure relief valve:
The micro switch at the pressure relief valve is used for
monitoring the maximum operating pressure in the central
lubrication system.
If a malfunction occurs in the system, the micro switch is
actuated.
The micro switch signal can be processed by any already
existing signal encoder, e. g. an on-board controller, or by
an external or integrated control unit.
The lubricant comes out under high pressure (250 bar)!
Wear safey goggles and also do not stay otherwise within the area of the pressure
relief valve in the case of a malfunction of the central lubrication unit!
Never work when the voltage (ignition) of central lubrication system or pump is
connected! Relieve the central lubrication system before you start the works!
