2.2.4 Sensor Y (Working position)
The sensor Y (18) is connected to the tractor signal distributor (16) via the 3-pin socket. From this sensor
the working position of e.g. the three-point hydraulics on soil-tilling work or the
lifter
on beet-harvesters. If
there is a switch box or a machine adapter (e.g. field sprayer) the computer receives its information about
the working position via the machine plug (4); the sensor is in this case without significance.
The magnet is mounted with the V4A bolt supplied to a part of the machine, which changes its position
from transport to working position. The sensor is then fixed to a static part of the tractor opposite to the
magnet. When in operation, the magnet must be exactly in front of the sensor. The light diode „ACTION“
lights up on the computer.
Diagram 312 090.81.1
Whenever the part of the machine which is being monitored varies in working position by more than 4 cm
in front of the magnet sensor, a second is fitted in the direction of the movement of the magnet. When the
machine is brought into transport position, the magnet should move at least 40 mm away from the magnet
switch.
Example: Tractor - three-point hydraulics
