11.3.1
Activation of Teach Mode “Auto”
The technician first enters teach mode by CANopen command. The default sub mode is “Manual”. Optionally,
he can teach the reference positions. Chapters
11.2.1 and
11.2.2 are here applicable as well.
Remark: reference positions can also be learned later, after change to sub mode “Auto”.
Now that the device is already in teach mode (sub-mode “Manual”), the sub-mode can be changed to “Auto“.
This can be done by a CANopen command.
11.3.2
Learning of floors in Teach Mode, Sub-Mode “Auto”
The technician carries out a teach trip. The direction is arbitrary. It is only important that the car passes by all
floor positions.
During this teach trip LIMAX33 CP-00 passes by the single floors and detects the positions of the floor magnets
using the floor detection sensor(s).
Whenever a floor magnet is detected in teach mode auto, LIMAX33 CP-00 learns the new floor at the position.
In case of lift installations with double-sided entries normally two floor sensors are necessary: one of them de-
tects the floor magnets on the first (front) side, the other on the second (rear side).
NOTE!
When the learning trip is carried out at a high speed, the individual floors are not learned
with the same precision as during a slow learn trip.
Like in manual Teach
11.2.3 the floor table will be filled with the single floor positions. But in Teach, sub-
mode “Auto”, the LIMAX33 CP-00 determines the respective index under which a certain floor is stored on its
own (in such a way that floor positions are increasing with an increasing index).
The floor sensor (of first side or of second side), which detected the floor magnet, determines the side. The side
information will also be stored in the floor table.
In case the first- and the second side sensor each detect a floor in between a distance of ±
“Door minimum dis-
tance”
1
, LIMAX33 CP-00 will store this as one floor with two sides; if the position where the first side is detected
and the position where the second side is detected are not exactly the same, first side takes the leadership con-
cerning the position entry in the floor table (by definition).
The same applies if e.g. a floor is already in the table on the first side and later a floor magnet is added on
second side (may be because a new door is added). In order to learn this second side of the floor, teach mode
Auto will be re-entered and LIMAX33 CP-00 will add the second side as soon as the second side floor magnet is
detected in between a distance of ±
“Door minimum distance”
around the already existing first side floor. After this
the floor will be double-sided (1
st
and 2
nd
side). In case the distance is bigger than ± “Door minimum distance
”
an own floor (only one side: on 2
nd
side) will be added.
Figure 18 and Table 8 (on next page) illustrate the learning of double sided floors.

„Door minimum distance” is a settings parameter, refer to Table 25
