REMARK!
After the learning the operator has to check each photoelectric barrier for functioning.
REMARK!
When a faulty photoelectric barrier is detected during the testing or when an obstacle is
present within the photoelectric barrier, the gate can be opened and closed in emergency
mode.
10.7.11 Sequence
pb
: Lockage function of the photoelectric barriers
Drawing 29
A lockage function by photoelectric barriers is possible in connection with the automatic closure. To
activate this function use the learning sequence.
The lockage function is only activated when the gate is open.
When the gate reaches the end position OPEN, the lockage function is initialised, which means it is in
its initial state “Automatic closure by lockage function approved”.
When a vehicle first passes the photoelectric barrier LSA and then the photoelectric barrier LSI, then
the interruption of LSA blocks the automatic closure and the interruption of LSI unblocks it and starts
the stay-open time. When driving in the opposite direction, the blocking and unblocking occur
accordingly.
