8 PNEG-1640 Smart IR Sensor
4. Basic Operation
The Smart IR Sensor will detect when the last feeder is full and immediately shut the Flex-Flo system off,
the yellow “Product Detected” LED will be lit and the display will read “Full”. When the feed falls away from
the sensor, it will count down a pre-determined delay time and then turn the Flex-Flo system back on.
It also includes a maximum run timer that will shut the system down if the auger runs too long in case of
an empty or bridged feed tank or a feed spill. Alarm contacts are available to provide remote notification
of a maximum run situation.
