The service menu of the Control Terminal (see description in chapter 3.)
can be used to check the metering wheel sensor.
The pulses of the metering wheel sensor can be tested individually in the
service menu in the "Inputs" line. The numeric characters 7 and 8
change between “1” and “0” in a given pattern, which allows to identify
the sense of rotation of the metering wheel.
To this end, slowly rotate the metering wheel and watch the display in
the Control Terminal. The tables show an extract of the numeric
character sequence which is repeated while the metering wheel rotates.

When the numeric character sequence is displayed in this order, the
sensor is OK.
If the display does not change when the metering wheels is rotated, the
cabling to the metering wheel sensor may be checked as follows:
1. When the plug has been removed from the metering wheel, both
digits must show “0”.
2. When pins 2 and 4 of the plug are connected, digit 7 must be “1”.
3. When pins 3 and 4 of the plug are connected, digit 8 must be “1”.
4. The tractor system voltage (approx. 12V) must be measured
between pin 1 (power supply) and pin 4 (earth) of the plug on the
metering wheel sensor.
In addition, a bale length of 1.28 m should be displayed after one
rotation of the metering wheel (reset the display to zero by one tying
process before this check).
The bale length is now displayed in the service menu under “L=”.
If the length is not shown properly although the sensor and its cabling
are faultless, the problem is in the program of the modules. In this case,
the baler must be newly configured.
