In this case, the control unit opens the valves
in a carefully coordinated sequence so that
only one valve is activated at a time, while still
providing all feeders with lubrication. The re-
sult is that the pump cycle time for each zone
is maintained.
7.3.3.2 Semi-automatic control
In this operating mode, every lubrication cycle
must be started by a CAN 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 lines are opened after
a delay which was conigured as "interval
time." If interval times are the same in multiple
lines, 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 lines still overlap, the
control unit actuates the zones as described in
the preceding section.
The pump cycle time for each zone is time-
dependent and is conigured by entering a
time value in hours, minutes and seconds.
The pump cycle time for units with W1 ill
level control can also be set in pulses, i.e., the
number of agitator revolutions.
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.
7.3.3.3 Control via CAN commands
In this operating mode, both the pump mo-
tor and the lubrication zone valves can be
controlled as desired via CAN commands. Any
parameter values that have been programmed
for interval and pump cycle times 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.
