Operation modes and Commissioning

- 41 -

The order of learning is absolutely arbitrary - not only concerning the single floors, but also the order of learning
of the reference positions and the floors. So, it is possible to save time by optimizing the order of events:
If



first one reference positions is learned,



after this one floor after the other on the way to the other side of the shaft is learned



and then the other reference position is learned, the time for one travel through the whole shaft can be
saved (flow of events similar to Figure 17).

11.2.1

Activation of Teach Mode, Sub Mode „Manual“

On delivery, there is no shaft information in the LIMAX33 CP-00 (neither a floor table nor reference positions)
this is the pre-commissioning mode. LIMAX33 CP-00 must learn the floor table and/or the reference positions.
In order to do this, the technician requests transition into teach mode via CANopen-command:



LIMAX33 CP-00 will transit to teach mode, the sub-mode will be “Manual” (default)

If the floor table of LIMAX33 CP-00 is not empty (normal mode) and the floor table should be corrected or ex-
tended for some reason (e.g. add, delete or shift the position of a floor), the technician carries out the transition

into teach mode in an identical manner as from the pre-commissioning mode (described above). The existing
floor table and the reference positions will be kept at the transition into teach mode.

In teach mode, there is an acoustic signaling by buzzer: there is a short acoustic signal every 2 second.

11.2.2

Learning of the (Limit Switch) References

(Limit switch) reference positions are used as references for calculation of the final- and inspection-limit-switch
positions, the pre-triggered-stopping system limits and the distance to the assumptive buffer for ETSL-calculation,

13.2.8.

The technician moves the car to the lowest possible position (normally this is the position where the car is on the
buffer). He signals to the control that the current position has to be learned as the lower (limit switch-) reference
position. For this purpose, the cabin must be in stand still. The control passes on this signal via CANopen to
LIMAX33 CP-00
The technician moves the car to the highest possible position (normally this is the position where the counter-
weight is on the buffer). He signals to the control that the current position has to be learned as the upper limit
switch reference position. The control passes on this signal via CANopen to the LIMAX33 CP-00. For this pur-
pose, the cabin must be in stand still.

If the technician tries to learn an upper reference on a position below the lower reference, this command will be
refused. The same applies if he tries to learn a lower reference on a position higher than the upper reference.

If the technician gives a CANopen-command to learn an upper reference while an upper reference position is
already available, the old upper reference will be overwritten. The same applies for the lower reference position.

Reference positions will be erased when teach mode is left to pre-commissioning mode, but they will be kept if

teach mode is left to normal mode.

Reference positions will also be kept on power cycle starting from teach mode.

NOTE!

The lower reference can be learned before the upper reference or vice versa. It is also possi-
ble to learn one reference first, then learn the floor table and at last learn the 2

reference.

NOTE!

If a power cycle happens starting from teach mode and both reference positions have been
learned, LIMAX33 CP-00 will restart in teach mode for the case that LIMAX33 CP-00 needs
also a floor table , reference positions will be available, but floor positions may be learned up
to that moment will be lost. The teach process can be directly continued with learning of the
floor table.
