Service
Loss sensors require regular service. Their surfaces must be kept clean. In damp conditions dirt may accumulate
on the sensor surfaces. Remove the dirt while still damp. Do not use a sharp tool, as the surface is a microphone
cover.
Check the condition of the pulse sensors and the secure fastening of the magnets from time to time.
The sensor for the amount of returns may also get dirty. It can be cleaned through the service door on the
housing of the returns threshing machinery.
Check the sensor operations on a regular basis by running the ”TEST” function of the equipment. Knock lightly on
the cover of each loss sensor to change the display reading of the pulse counter to show the sensors are intact.
The left and right side sensors have parallel connection. Therefore they produce pulses in the same counter!
To test the forward speed sensor, drive the combine forward.
Test the pulse sensors by running the machinery. A regular increase in the pulse reading shows that the sensors
are intact.
If there is something wrong, check for loose cable connections.
If the sensor mode remains at HI all the time, the sensor is ”open” or the cable is broken
the connector loose.
If the sensor mode remains at LO all the time, the sensor is ”closed” or the cable is short-circuited.
In case of combines with a pick-up reel driven by belt variator, the following shall be kept in mind:
When adjusting the belts, make sure that after the adjustment of the mechanical limiter the electrical limiter
switches are adjusted to stop the servomotor shortly before the limiter nut stops the screw. This ensures that
automatic adjustment cannot damage the servomotor.
