Lubricators CONCEPT4
Advance fill level warning The lubricator is equipped with a sensor that signals an advance
fill level warning when a remaining fill quantity of 80 cm
3
grease is
reached (20% usable cartridge volume remains). The replacement
sourcing or substitution of the cartridge can be planned without time
pressure within the remaining running time.
The visualisation of the advance fill level warning via an external
controller (PLC) should only take place after three consecutive signal
indications.
The advance fill level warning is a purely informative signal.
The lubricator continues to process all control signals until the empty
cartridge level is detected.
