2.7.1 FEEDER RUN-TIME SUMMARY
Stable and consistent operation of the feeders is important in achieving the best
possible performance from the sorter. The feed rate through the sorter should be
balanced with the output of the process so that the feeders do not stop to wait for
product any more than necessary. The objective is to run the feeders slightly faster
than product is being supplied to the sorter. The installation should include a surge
hopper above the sorter, so that when the hopper runs out of product, the feeders
can remain off and product can accumulate in the hopper. This will allow the
feeders to run for a longer time when they restart. There are several level control
strategies to stabilize feeder operation, but no matter how the level sensors are
configured, the most important factor is setting the feed rate to match the output of
the process. Information on the STATUS SCREEN is provided to monitor feed rate
adjustment.
For each feeder, TOTAL RUN TIME since the last reset, and PERCENT ON and NUMBER
OF STOPS during the last hour are shown. The TOTAL RUN TIME can be reset to zero
by touching the RESET TIME button. The PERCENT ON shows the fraction of time
that each feeder ran during the last hour. The NUMBER OF STOPS shows the number
of times that each feeder cycled off by the level control or was switched off.
Monitoring these statistics will help to optimize the feeder rate settings.
