13.2.4.1 Door bridging levelling
The conditions for door bridging levelling are:
1. Door bridging command for levelling has been given by CANopen.
2. Actual position is in the door zone for levelling of that floor, the door bridging levelling has been ena-
bled for

13.2.4.3. The door zone extends from the flush position of the relevant floor (due to CANo-
pen-command) MINUS door zone size for levelling to flush position of the relevant floor (due to CANo-
pen-command) PLUS door zone size for levelling. Concerning door zone size for levelling see

14.2 .
3. Actual speed < 0.8 m/s
If all three conditions listed above are fulfilled, SR(1/2) closes due to door bridging levelling.
13.2.4.2 Door bridging re-levelling
The conditions for door bridging re-levelling are:
1. Door bridging command for re-levelling has been given by CANopen.
2. Actual position is in the door zone for re-levelling of that floor, the door bridging re-levelling has been
enabled for

13.2.4.3. The door zone extends from the flush position of the relevant floor (due to
CANopen-command) MINUS door zone size for re-levelling to flush position of the relevant floor (due to
CANopen-command) PLUS door zone size for re-levelling. Concerning door zone size for re-levelling re-
fers to

14.2 .
3. Actual speed < 0.3m/s
If all three conditions listed above are fulfilled, SR(1/2) closes due to door bridging relevelling.
13.2.4.3 Door bridging Command by CANopen
Door bridging is enabled by CANopen-command. This Command contains
1. Information if door bridging should be enabled for levelling or for re-levelling
2. Number and position of that floor, the door bridging should be enabled for
3. (entry-) side (1
st
side, 2
nd
side or both sides) of the floor.
If one of the conditions mentioned above does not fit, LIMAX33 CP-00 will not accept the door bridging-
command and neither SR1 nor SR2 will close.
In case the three conditions mentioned above do apply and the additional conditions concerning speed and
zone do apply, SR1 or/and SR2 will close. Concerning the details about the dependency SR1/SR2 from 1
st
side/2 nd side / both side floor and bridge command 1 st side/2 nd side / both sides refer to the table in the Appen-
dix “bridging operations for double sided floors” in the CANopen Specification. In this table it can be also
found, how LIMAX33 CP-00 deals with the situation that there is only one SR, but a double-sided door.
The following list specifies for accepting/not accepting a CANopen door bridging command.

Door bridging cannot be enabled for more than one floor at the same time.

It is possible to switch directly from door bridging levelling to bridging re-levelling
(concerning one and the same floor)

It is not possible to switch directly from door bridging re-levelling to bridging levelling

It is not possible to switch directly from door bridging re-levelling or levelling to door bridging re-levelling
or levelling of another floor

In case of a double-sided floor it is possible to switch directly from one side to the other, from one single
side to both sides or from both sides to one single side.

door bridging (levelling or re-levelling) will stay enabled until it is
a.)
disabled by CANopen-command or
b.) until an invalid CANopen-levelling/re-levelling command is received (e.g. wrong floor position) or
c.) until CANopen-levelling/re-levelling command is received which is indeed valid, but for another floor
than a CANopen-levelling/re-levelling which is already pending
