When turned ON and the seat switch closed, all units of the machine are set to „initial
position“.
This means that the control electronic triggers all units (lifting elements and motors).
Lifting elements will be lifting up as long as they are not switched off by the micro-
switch controlling the upper limit position and integrated in the lifting element.
This means that the outputs for the lifting elements are powered for approx. 6 sec
every time the machine is switched on. During this time a voltage can be measured at
the outputs for the lifting elements.
Motors are off and the cleaning unit LED indication in the operator panel extinguishes.
The drive controller is transmitted the release signal.
Should the seat switch not be activated, the motors will also be turned off - for safety
reasons - but the lifting elements will not be lifting and the travel drive controller will
not be released either.
The only exception: water suction by hand hose (B1100).
