3 Storage of upper cut-out points
4 Lifting carriage positioning run
5 (not used)
6 Storage of safety stop position and additional acoustic
signal on further lowering of support arms
7* Potentiometer test
8* Activation / diagnosis function
9 PC mode in conjunction with PC diagnostic software
Tab. 2: Encoding switch positions
* If a fault occurs during the test, this is encoded and stored in
the EEPROM. The control system can then no longer be set to
operating mode. If operating mode is selected after a fault has
occurred resulting from this test, both LEDs flash alternately
(green/orange). This fault can only be reset by successfully
implementing the activation/diagnosis function procedure
(eliminate any faults or replace defective components).
