8.1.11. Sequence PB: Lockage function for the photo-cells
Drawing 19
When using photo-cells in connection with the automatic closure for both wings, a lockage
function is possible. To activate this function use the learning sequence.
- The lockage function is only activated when the gate is opened.
- When the gate reaches the end position OPEN, the lockage function is initialised.
This means: when a vehicle passes through the gate from the outside, a signal from
LSA (photo-cell outside) blocks the automatic closure function. Only the signal from
LSI (photo-cell inside) removes the blocking and starts the stay-open time. When a
vehicle passes through the gate from the inside, a signal from LSI blocks the
automatic closure function. Only the signal from LSA removes the blocking and
starts the stay-open time.
When sequence
PB
is activated by button
LERN
, the present selection is displayed. With
the button
BT
the value can be selected (see table).
Return to the learning sequence using button
LERN.

When the photo-cell is interrupted, closing of the gate wing / wings is only
possible, when the vehicle / person has passed both (LSA and LSI) photo-cells.
