Problem Cause Solution
Moisture reading goes to
5%. Ground strap on
moisture sensor is not
getting a good
connection. Ensure the ground strap touches bare metal where
it contacts the sheet metal.
Moisture reading
decreases
drastically/suddenly. Determine if reading
decreases occur when
using a business-
band, two-way radio. Move the radio antenna and cable as far from the
moisture sensor and sensor cable as possible. If
the antenna wire must cross the moisture sensor
cable ensure it crosses at a 90-degree angle.
Erratic moisture sensor
signal with moisture
sensor installed in auger
tube. The flighting of the
combine grain tank
fill auger was not
completely cut down
to the shaft where the
moisture sensor was
installed. Remove flighting completely to auger shaft where
the moisture sensor installs
Moisture continually
reads 5% with elevator
mount. Buildup on proximity
switch causing auger
to run constantly
preventing the
chamber around
sensor from filling. Remove wing nut at top of moisture sensor and
remove sensor. Disconnect the power to the
electric motor by removing the fuse. With a dry
cloth, reach inside the slot for the moisture sensor
and wipe off the proximity sensor.
Proximity sensor is
out of adjustment. Remove the side cover on the elevator mount. Do
NOT attempt to remove the sensor. Locate the
potentiometer adjustment screw on the backside of
the proximity sensor. Using a small screwdriver,
turn the screw slowly clockwise until the unit turns
on without any grain. Then turn the screw
counterclockwise 4 full turns or 8 half turns. The
motor should stop running. Replace the side cover.
