7.3. Functional description in single-line
systems with KFGC (CAN bus)
pump unit
The general functional description for single-
line systems with a KFG pump unit also applies
for the design with CAN bus pump control.
7.3.2 Multiple lubrication zones
Using the integrated LC-CAN 5000
control unit, a single-line system can be
divided into up to four individually controllable
lubrication zones. This is performed using
electric switch valves which separate the indi-
vidual lubrication zones from each other.
Four conigurable digital inputs/outputs are
available to control each lubrication zone. This,
as well as the type of valves used, provides
various possibilities for setting up lubrication
zones.
7.3.1 Systems with directional
solenoid valves
Directional solenoid valves can be used to
create a single-line system with up to four
lubrication zones. The system can be equipped
with or without functionality to monitor pres-
sure build-up and reduction.
Note
Depending on the ield of application and the
system design, a compact 5/4 directional
solenoid valve can be used in place of individual
3/2 directional solenoid valves.
