3.4.2 Frame and height inclination redundant control device
On the platform, there is an additional angle sensor which provides a 12V output
signal if the frame is within the limit value of 3°.
This sensor is connected in parallel to the limit switch that controls that the
platform is at a height lower than the transport height (the 12V output signal is
interrupted if the platform is lifted above the transport height).
These devices are part of another electromechanical safety ring that prevents
the movements of the machine, disabling the outputs of the control unit and
disconnecting the other block valves on the levelling cylinders.
