the vehicle it is necessary to put the wedge under the rear wheel.
If you use the external traffic lights option (o4), the RED light trips
after the wedge is inserted. Then it is possible to control the
loading ramp system (shelter, door, loading ramp).
If you use a microswitch (closing contact), terminals Y5/8 (J20 +) and
Y5/10 (J20 S) produce an 8.2 kOhm resistance. The microswitch
(closing contact) is connected to terminals Y5/9 (J20 -) and Y5/10
(J20 S).
If you use an electronic sensor, the brown wire of the sensor (+) is
connected to terminal Y5/8 (J20 +), the blue wire (-) to terminal Y5/9
(J20 -) and the black wiring wire (S) to terminal Y5/10 (J20 S).
Attention!
