Operation modes and Commissioning
11.1.2 Teach Mode
11.1.2.1 General
In order to reach the normal mode (for normal lift operation), it is necessary to teach a valid floor table and/or
reference positions using a commissioning process. This can only be done in teach mode.
There are two kinds of teach procedures: manually and automatically. Therefore, the teach mode provides two
sub-modes:
teach sub-mode manual, refer to 11.1.2.2
and teach sub-mode auto, refer to 11.1.2.3
Concerning the safety output states both modes behave in the same way.
Reference positions can always be learned in teach mode regardless of the sub-mode.
If reference positions are needed but not available, the behavior of the safety outputs is the same as in pre-
commissioning mode 11.1.1.
If reference positions are available, the behavior of the safety outputs will have the following states:
Table 6: Safety output states in teach mode or teach auto mode when reference positions are available
Open if a (pre-tripping-) overspeed-function trips*) or in EN81-21 state outside of the range
between the (direction dependent) inspection limit switches (provided inspection functions are
not disabled). Otherwise closed.
If a (final-tripping-) overspeed-function trips*) or pre-triggered stopping system trips*) or safety
function “working platform” trips *), the (solid state-) contact is open. Otherwise closed.
*) provided these safety functions are not disabled 14.1.2
Teach mode (regardless of the sub-mode) can be left to normal mode by CANopen command, refer also to
CANopen specifications.
If the teach process was not successful (e.g. because no floor or only one floor has been learned, or because
floor positions are not in an increasing row according to their numbering), LIMAX33 CP-00 will refuse a demand
to enter normal mode and will stay in teach mode. If the teach process was successful LIMAX33 CP-00 will ac-
cept the demand to enter normal mode and the floor table will be stored in a non-volatile way.
Afterwards the mode changes to “normal”.
Teach mode (regardless of the sub-mode) can also be left to pre-commissioned mode by another CANopen
command, refer also to CANopen specifications. In this case an existing floor table will be erased. Reference
positions which may be available in teach mode, are also erased in this case.
If a power cycle occurs during teach mode or if a RESET command by CANopen was given all floors positions
learned up to that moment will get lost.
In opposite to this, reference positions will be kept at power cycle or a RESET - provided both of them are avail-
able (they are stored in a non-volatile way as soon as both reference positions have been learned).
LIMAX33 CP-00 will restart in pre-commissioning mode after power cycle happened in teach mode when no –
or only one reference position has been learned. If both reference position have been learned in teach mode, a
power cycle in teach mode will cause immediate re-entering of teach mode or direct entering of normal mode if
no floor table is needed due to the configured safety function.
