Braking and stopping distances as well as flush positions are then adjusted by shifting the
corresponding magnets in these lifts.

3.4.2 Teach-in procedure by lifts with incremental encoder

3.4.2.1 Lifts with more than 2 floors
Before starting the calibration process, it is essential to measure accurately switching-on-
zone of the leveling switch SGM on the 2nd floor and to enter this value in parameter "Vane
length" in the menu "General param.". By this setting the lift controller is able to determine
automatically the resolution of the encoder (parameter "Incr./m").
The lift must be leveled in the lowest floor when starting the teach-in procedure (level switch
SGM must be switched on). The teach-in starts through the menu item "Teach in trip" -
"Complete". The lift then moves upwards through the shaft to save the floor positions (center
between the two switching points of SGM). After that several trips with different speeds are
automatically carried out to determine the braking and stopping distances.
After the complete teach-in trip, the parameters can be saved by pressing ENTER; the lift is
then ready for operation. If the switching points of the leveling switch SGM were not set
exactly symmetrical to the level position, a flush correction is still to be done.
3.4.2.1 Lifts with 2 floors
For lifts with just 2 floors, the encoder resolution (parameter "Incr. /m") must be determined
manually before starting the teach-in trip.
The easiest way is to set the parameter "Incr./m" first to a value of 1000. Then the state
display 4 may be selected (home display, then selected with cursor keys) to notice the
current position (displayed at this time in brackets) . As next the lift has to be moved 1m as
accurately as possible (e.g. by inspection control; best done by markings the positions on
the guide rail). Then read the new position in the state display 4 and enter the position
difference as parameter "Incr./m".
After that, the learning journey can be carried out as described above.

3.4.3 Teach-in procedure by lifts with absolute encoder

3.4.3.1 Setting the floor positions
If the floor positions are known (e.g. from the shaft drawing), then these values can be
entered; either in the "Floor height" menu as an absolute value or the "Floor distances" menu
as a relative value.
If the values are not known, the floor position can be measured in the menu "Measurement".
For this purpose, the lift can be operated with either the emergency recall operation pushes
or inspection control pushes as well as with the sub menu "Travel movements" to the
individual floors. If the lift is well levelled (difference to floor level should not be greater than
50mm), then the floor number is entered and the menu item "Measure floor" is selected to
measure the floor position. This process can be performed in any order and repeated any
number of times; the important thing is that each level must be measured at least once.
