6.3.2.2 Semi-automatic control unit
In this operating mode, every lubrication cycle
must be started by a CAN START command.
When the control unit receives the START
command, the lubrication scenario conigured
in the selected parameter set is loaded and
processed.
The valve for the lubrication zone conigured in
the parameter set as the start zone is opened.
The valves for the other zones are opened
after a delay, which is conigured as "interval
time." If interval times are the same in multiple
zones, the valves are actuated according to the
numerical sequence conigured. This prevents
the pump from having to supply multiple lu-
brication zones at the same time. If the pump
cycle times for multiple zones still overlap, e.g.,
in block operation, the control unit actuates the
zones as described in the preceding section.
The pump cycle time for each zone is based on
time or pulses and is conigured by entering
the time in hours,
minutes and seconds or a number of pulses
(corresponding to revolutions of the pump's
agitator).
The lubrication cycle can only be aborted using
a CAN STOP command. If a new lubrication
cycle is started by a CAN START command
while another lubrication process is ongoing,
the ongoing process is aborted and the new
process is started.
The system stops after completion of the lubri-
cation cycle. The next lubrication cycle must be
initiated by another CAN command.
6.3.2.3 Control via CAN commands
In this operating mode, both the pump motor
and the lubrication zone valves can be con-
trolled as desired via CAN commands. Interval
and pump cycle times which are conigured in
the parameter sets are ignored.
When multiple lubrication zones are used,
care must be taken that multiple valves are
not opened at the same time during a pump
cycle, as this can result in undersupply of the
lubrication points.
