7.4.1 Position detection in the brush head lifting element

The lifting element for the brush head features integrated position detection.
The position detection is supplied with 24 V via the machine control unit A01.X13:1
(+) and A01.X13:7 (-). The reference signal for the brush head position can be
measured against supply plus or minus at the central control unit at A01.X15:5.
This signal must be between 0.3 V and 2.3 V. Voltage values outside this range are
detected and output as errors (message 1.2.6.3.).
This message is also output if the "ACTUAL" signal of the position detection does
not correspond to the "TARGET" value within a defined time.
The power output of the lifting element is A01.X11:1 and 4.
