4.4.2 Oil + air lubrication systems with
control unit
Oil + air lubrication systems with a control unit
contain a programmable electronic control unit
that can be used to control and monitor the sys-
tem. Electronic control units for oil + air lubrication
systems are designed as pulse generators, i.e., they
set the interval time. Depending on the model
design, the electronic control unit allows configura-
tion of the interval time, pump delay time and the
number of pre-lubricating cycles. One or more
pre-lubricating cycles with short interval times can
be triggered prior to starting up the machine in
order to provide an adequate quantity of lubricant
for the bearings that require lubrication and/or to
build up a fully developed oil streak in the lubrica-
tion point line, before the machine starts running.
The pump cycle time is 60 seconds and cannot be
adjusted.
The electrical connection of the monitoring units is
established at the terminal strip of the compact
unit's electronic control unit. The control unit
directly monitors the operation of the oil pressure
switch, air pressure switch and fill level switch. Oil
+ air lubrication systems with an electronic control
unit are supplied with all internal wiring fully
connected. Depending on the electronic control
unit's model design, a signal line for fault monitor-
ing can be run outwards to connect to the machine
control unit via a cable fitting mounted on the
compact unit.
Details on the function and operation of the com-
pact unit and the control unit can be found in the
assembly instructions for the compact unit and the
operating instructions for the electronic control
unit which are included in the scope of delivery of
an oil + air lubrication system.
