with dry contact, signal smoothing,
max. 24 VDC, for greases of NLGI Grade ≥ 2
The following functions are integrated for the
KFG pump unit with signal smoothing:
Possible isolation of power supply voltages
between fill level monitoring and pump
power.
Fill level information can be accessed even
during interval time.
Reverse voltage protection provided in the
pump supply line.
Optional timeout times.
The various functions are realized internally
using jumpers, according to the custom-
er-specific pump design.
The monitoring device is connected via a
4-pin circular connector, which is plugged into
the base of the pump unit.
