2.6.6.5 DRIVING AROUND CORNERS
The two proximity switches 1B9 and 1B10 are mounted on the steering axle for sensing the steering lock.
They are actuated when the steering lock is accordingly.
The two proximity switches are supplied with 24 VDC from the voltage converter via X6:1 or X7:1. The sensors
are connected to battery negative via terminals X6:3 or X7:3. They are activated by the steering cylinder.
When travelling straight ahead, both sensors are activated and battery negative is applied to terminals :6
and :20 in connector 1X13 of the electronic traction control unit. When the steering lock is over 40°, the sensor
in question (1B9 = left-hand sensor, 1B10 = right-hand sensor) is no longer actuated and the battery negative
signal at 1X13:20 (left) or 1X13:6 (right) is cut off. As a result, the motor on the inside curve is turned off by
means of the directional contactors.
