Divider block cycle time - The operator will need to set the lube system pumps
according to the recommended divider block cycle times. It is helpful for the
operator to have a display of divider block cycle time in seconds. This will be
used to adjust the lube pumps as the pumps wear out and when the pumps are
replaced to set divider block cycle times.
Time since last Pulse - It is helpful to have a display of the timer timing so the
operator can see a change and show that something is happening.
Average Cycle Time - Cycle time will vary a few seconds from cycle to cycle. It is
sometimes helpful to display a cycle time that has been averaged over 5 to 10
cycles.
Total Oil Consumed - Total oil consumed can be useful to the operator to know
how much oil is being used for the lube system and thus how much oil to order.

EXAMPLE FLOW DIAGRAM TO CREATE SHUTDOWN
Figure 4-7 flow diagram is a suggested method of creating a shutdown within
the PLC from a cycling digital input. This is only a suggestion as there is no way
of providing logic for all control systems.
