Level Sensor Programming
The level sensor probe tells the feed center PLC what the powder level is in
the powder source. Follow these procedures to program the level sensor
probe to recognize the level of powder in the feed source.
There are two different kinds of sensor probes, identified by the number of
programming buttons on the probe.
Turn on the afterfilter exhaust fan and thoroughly fluidize the powder in the
hopper or box before you program the level sensor probe.
