Pump units of the KFGC (CAN bus) series for rotary application
231-3034-EN
Pump units of the KFGC (CAN bus) series are
reservoir pump units (piston pumps) with an
integrated control unit for on-demand lubri-
cant supply to centralized lubrication systems
with progressive distributors or to single-line
systems. A special feature of pump units of
the KFGC (CAN bus) series is the integrated
LC-CAN5000 control unit, which is distin-
guished by the following characteristics:
CAN bus interface (SAE J1939, optional •
protocols available), which allows units to
be integrated into the CAN bus networks
of machines and systems. The lubrication
system is monitored, operated and config-
ured through the CAN bus, for example at
the process control level.
There is also the option of configuring and •
operating the pump unit without CAN bus.
The control unit is able to control and •
monitor up to four independent zones and
to supply them from a single pump unit.
Electric switch valves which are controlled •
based on the parameters set for each
individual lubrication zone are placed in
the main line. The control unit has up to
four solid-state switching outputs for this
purpose.
In addition to valve control, the outputs •
can also be configured as digital outputs
for other purposes.
In addition to the outputs, up to four digital •
inputs are available, e.g. for monitoring
piston detectors, pressure switches or
other switching contacts.
A detailed description of the electrical •
connections can be found in the operating
instructions for the KFG series of pumps.
The control unit's comprehensive monitoring
functions allow potential faults to be detected
early. This includes, among other things,
monitoring the fill level in the lubricant reser-
voir, monitoring the signal lines on attached
components for line breakage, and monitor-
ing the switching outputs for short circuits.
Important system events such as a low fill
level in the lubricant reservoir are saved by
the control unit and given a time stamp. This
allows the causes of operational faults to be
determined more easily.
The flexible parameters and configuration op-
tions allow custom lubrication concepts to be
implemented for each individual lubrication
zone in the system. The control unit can store
up to 16 sets of parameters. Each set of pa-
rameters contains all the information required
to control and monitor the lubrication process.
This means that different lubrication scenari-
os can be prepared and saved then called on
when needed.
