5. Design and function
5.6 KFGC (CAN bus)
Pump units of the KFGC series are pump units
from the KFG series with an integrated CAN
bus control unit.
The integrated LC-CAN 5000 control unit of-
fers the following special features:
CAN bus interface (SAE J1939), which
allows units to be seamlessly integrated
into the CAN bus networks.
The lubrication system can be monitored,
bus.
and operated via the IrDA interface.
Moreover, the control unit is able to control
and monitor up to four independent zones and
to supply them from a single pump unit.
To achieve this capability, 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 above-mentioned outputs,
up to four digital inputs are available, e.g., for
connecting piston detectors, pressure switches
or other switching contacts. A detailed de-
scription of the electrical connections can be
found in
Chapter 4 in the assembly
instructions.
The control unit's comprehensive monitoring
functions allow potential faults to be detected
early. This includes, among other things, moni-
toring the fill level in the lubricant reservoir
(minimum), monitoring the signal lines on at-
tached components for line breakage, and
monitoring the switching outputs for short
circuits.
Important system events such as a low fill level
in the lubricant reservoir (minimum) 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 scenarios
can be prepared and saved then called on
when needed.
Chap
t er 4 in the assembly instructions con-
tains instructions on configuring the system.
